A new subsystem requires separate evidence and a separate proposal. - -Status meanings: - -- `[ ]` not started or not proven -- `[x]` implemented and verified -- `DEFERRED` deliberately outside the current implementation sequence - -## Current summary - -- [x] Fresh primitive-oriented design written and repeatedly reviewed. -- [x] Product UI changes explicitly excluded. -- [x] Current orchestration skill now teaches setup-run for new worktrees, batch processing, - `agentTerminalHandle` preference, and the custom-argv setup-policy limitation. -- [x] Phase 0 command/skill compatibility work complete. -- [x] Phase 1 local Run, mailbox, lifecycle, and idempotency primitives complete. -- [x] Phase 2 same-server composed worker lifecycle complete. -- [x] Phase 3 connected-server federation complete. -- [x] Revalidate Phase 3 after the 2026-07-24 post-rebase dogfood exposed a renderer-adoption - process-identity regression. -- [x] Phase 4 structured worker output is implemented with passing automated coverage and physical - local, mixed-version, restart, disconnect, and Windows-home to Mac-worker evidence; optional - symmetric acceptance checks remain tracked below. -- [x] Hard-cutover migration fence implemented and locally verified; branch-head CI remains the - final remote check. - -## Scope invariants - -- [x] Agents choose decomposition, topology, placement, parallelism, and recovery strategy. -- [x] Low-level worktree, terminal, setup, and handoff commands remain independently usable. -- [x] Every composed mutation with external effects returns explicit effects and an honest outcome; - control-plane-only mutations return their exact resource receipt. -- [x] Worker assertions remain labeled as worker reports, not Orca-verified correctness. -- [x] Silence alone never proves worker death or triggers replacement. -- [x] Multi-server Runs use one authoritative Run home and connected worker servers. -- [x] Runtime/server/host identity mechanics remain hidden from ordinary agent commands. - -Explicit non-goals: - -- [x] No product dashboard, Run UI, badges, or coordinator chat UI. -- [x] No scheduler, automatic placement, capacity allocator, fairness, or priority aging. -- [x] No automatic retry or replacement based on silence. -- [x] No commit, branch, merge, integration, or target-ref tracking. -- [x] No filesystem read-only/writer enforcement. -- [x] No generalized ACL, organization, role, or worker-profile system. -- [x] No replicated Run database, leader election, or automatic Run-home failover. -- [x] No dead-letter/poison-message workflow. -- [x] No universal provider-session or transcript framework. - -## Phase 0 — Vocabulary and current-agent ergonomics - -### Command compatibility - -- [x] Remove or rename the existing scheduler-like `orca orchestration run --spec` before shipping - lightweight `run-*` commands. -- [x] Publish the canonical command map in CLI help. -- [x] Define aliases or explicit deprecations for any renamed current command. -- [x] Keep current flat task commands unless a separately justified CLI migration changes them. -- [x] Require explicit destructive reset scope; bare reset must not imply reset-all. - -### Skill and recipes - -- [x] Teach that `check --wait` returns a message batch, not one message. -- [x] Teach processing every returned message and waiting until expected Dispatches settle. -- [x] Document crash-safe explicit acknowledgment and redelivery of an unacknowledged batch. -- [x] Prefer `agentTerminalHandle`, then legacy `startupTerminal.handle`, then exact terminal-list - resolution. -- [x] Pass `--setup run` for new worktrees by default. -- [x] State a concrete reason before using `--setup skip` or `--setup inherit`. -- [x] Preserve `start-immediately` as the normal setup/agent startup policy. -- [x] Warn that the two-step custom-argv launch cannot preserve explicit `wait-for-setup`. -- [x] Add executable current-version recipes for local fan-out, new worktrees, completion/failure, - questions, timeout recovery, and restart limitations. -- [x] Ensure installed, bundled, repository, and generated orchestration skill copies stay in sync. - -### Phase 0 acceptance - -- [x] An agent reading only CLI help and the skill can select current versus new worktree correctly. -- [x] The agent starts all independent workers before blocking. -- [x] The agent cannot mistake the old scheduler Run for a lightweight namespace Run. -- [x] Recipes contain only commands supported by the matching shipped CLI version. - -## Phase 1 — Run, mailbox, lifecycle, and durable mutation receipts - -### Lightweight Run - -- [x] Add a Run table with stable Run ID, objective, created/updated timestamps, and home database. -- [x] Add mandatory Run association to new Tasks, Dispatches, Messages, deliveries, and questions. -- [x] Migrate pre-Run orchestration rows into one unbound, inspect-only legacy Run. -- [x] Keep old scheduler-run storage distinct from lightweight Runs. -- [x] Implement `run-create`, `run-use`, `run-current`, `run-list`, and `run-show`. -- [x] Bind a coordinator pane explicitly; never infer a Run from a worktree or sole candidate. -- [x] Store one active mailbox consumer generation per Run. -- [x] Rebinding fences the old consumer and cancels its active waiter. -- [x] Do not implement Run archive/delete in V1. - -### Logical routing and prompt safety - -- [x] Add stable `run:` and exact `dispatch:` message recipients. -- [x] Do not add a task-recipient retargeting rule in V1. -- [x] Make send, ask, reply, completion, heartbeat, and runtime notices inbox-only. -- [x] Ensure only explicit dispatch injection and terminal-send operations can modify terminal input. -- [x] Define send success as durable acceptance, not observation or action. -- [x] Rename or remove `check --inject` if its name implies remote delivery. -- [x] Reject explicit Run/recipient targets from federated workers when the only valid destination is - their authenticated Run home. - -### Crash-safe inbox consumption - -- [x] Add one FIFO mailbox sequence. -- [x] Bound each actionable delivery to 50 messages. -- [x] Allow one outstanding Delivery and one active actionable waiter per Run mailbox. -- [x] Return the identical Delivery ID and batch until acknowledgment. -- [x] Implement whole-batch idempotent acknowledgment. -- [x] Bind Delivery acknowledgment to the current consumer generation. -- [x] Implement atomic `ack -> check -> register waiter`. -- [x] Keep peek/all/history modes read-only. -- [x] Treat type filters as wake predicates only; return the oldest full actionable batch. -- [x] Return typed timeout, cancelled, connection-lost, waiter-exists, stale-delivery, and - consumer-fenced outcomes. -- [x] Preserve unacknowledged mail across client and Orca process restart. - -### Truthful lifecycle - -- [x] Require `outcome=succeeded|failed` on terminal worker reports. -- [x] Map authenticated succeeded reports to Dispatch succeeded and Task completed. -- [x] Map authenticated failed reports to Dispatch failed and Task failed. -- [x] Persist stale/foreign reports as history without lifecycle mutation. -- [x] Reject malformed lifecycle transitions with typed missing/invalid fields. -- [x] Label result provenance as `worker_report`. -- [x] Apply every terminal transition as one transactional compare-and-set. -- [x] First committed completion, stop fence, or abandon wins. -- [x] Make duplicate identical completion idempotent. - -### Questions - -- [x] Model a question as durable message/thread state, not a task gate. -- [x] Default ask from an active Dispatch to its owning Run mailbox. -- [x] Record one idempotent first answer from the current Run consumer generation. -- [x] Reject conflicting later answers. -- [x] Resume by original message ID after timeout or disconnect. -- [x] Recover a lost ask-acceptance response through the same mutation retry receipt. -- [x] Close pending questions when their Dispatch stops or is abandoned. -- [x] Wake closed question waits with `dispatch_inactive`. - -### Narrow pane authority - -- [x] Mint an unforgeable per-Dispatch capability at lifecycle injection. -- [x] Carry the capability outside user-controlled request parameters on native, WSL, and SSH CLI - bridges. -- [x] Persist only its verifier or secure-store reference. -- [x] Verify capability, exact managed pane, Dispatch ID, and process incarnation for lifecycle calls. -- [x] Revoke/fence the capability on stop, abandon, or replacement. -- [x] Do not generalize this into user/role access control. - -### Durable mutation ledger - -- [x] Let clients retain/reuse one opaque retry request ID after unknown acceptance. -- [x] Before effects, persist authenticated caller/peer, request ID, canonical payload hash, - operation state, and receipt. -- [x] Join concurrent identical mutations or return the recorded result. -- [x] Return `request_mismatch` for the same request ID with a changed payload. -- [x] Cover Run/Task creation, send, ask, reply, acknowledgment, start, stop, and abandon. -- [x] Persist dedupe receipts across Orca restart. - -### Phase 1 acceptance - -- [x] Two Runs on the same runtime never mix tasks or mail. -- [x] An old coordinator cannot acknowledge or reply after `run-use` fences it. -- [x] A returned but unacknowledged batch is replayed after client/runtime restart. -- [x] Success, failure, stale completion, malformed completion, and duplicate completion tests pass. -- [x] Ask timeout/resume, same reply replay, conflicting reply, and stopped-Dispatch tests pass. -- [x] A forged pane/handle field cannot mutate lifecycle state. - -## Phase 2 — Same-server composed worker lifecycle - -### Command grammar and topology - -- [x] Implement `worker-start`, `worker-show`, `worker-read`, `worker-stop`, and - `worker-abandon` for workers owned by the Run home. -- [x] Current worktree creates one fresh agent terminal unless `--terminal` is explicit. -- [x] Named existing worktree creates one fresh agent terminal unless reuse is explicit. -- [x] Current/existing worktrees do not rerun creation-time setup or configured tabs. -- [x] New child worktree uses agent-first creation and reuses its returned agent terminal. -- [x] New top-level worktree uses agent-first creation with independent Orca lineage. -- [x] Reject child/top-level creation for folder projects before effects; use current/existing folder - workspaces instead. -- [x] Pass the supported exact repo, base, lineage, display/comment metadata, and setup options to - the existing worktree primitive rather than duplicating policy. `--on` owns connected-server - placement; project/host convenience selection remains on low-level `worktree create`. -- [x] Require a configured agent launcher before any mutation. -- [x] Reject selector/option conflicts before effects for current/existing worktrees. - -### Setup and startup - -- [x] Omitted setup on a new worktree resolves to `run` for orchestration starts. -- [x] No configured setup hook resolves to `not_configured`, not failure. -- [x] Preserve repository `setupAgentStartupPolicy`. -- [x] Preserve whether setup came from an explicit request or Orca's orchestration default across - connected-server starts. -- [x] Default `start-immediately` launches setup and agent side by side. -- [x] Under `start-immediately`, setup outcome never gates Dispatch readiness regardless of when - it is observed. -- [x] Track the setup command's exit code without waiting for its interactive terminal shell to - exit or closing the setup tab. -- [x] Register the completion observer before replaying bounded recent output so fast local setup - commands cannot finish in an observation gap. -- [x] Carry the exact created setup terminal handle; never infer setup identity from a display - title shared with configured tabs or split panes. -- [x] Scope completion signals to a private per-invocation token and preserve uncertain terminal - outcomes as running rather than converting a disconnect into setup failure. -- [x] The return receipt contains the latest setup state. -- [x] Only post-return setup state changes emit a typed setup notice. -- [x] Setup failure never automatically stops or fails an already-ready worker. -- [x] Explicit `wait-for-setup` completes setup successfully before agent launch and task injection. -- [x] Under `wait-for-setup`, setup failure produces start failure before task delivery. -- [x] Custom-argv two-step launch is rejected or clearly unsupported under `wait-for-setup`. - -### Start operation and receipts - -- [x] In one transaction, create a starting Dispatch, move the Task, and record the mutation request. -- [x] Persist the accepted Dispatch ID in a pending start receipt so restart recovery returns an - exact `worker-show` command. -- [x] Persist before/after stage receipts around irreversible effects. -- [x] Return only `ready`, `failed`, or `outcome_unknown`. -- [x] Define ready as TUI idle, durable Dispatch attachment, and accepted lifecycle/task input. -- [x] Echo effective timeout, setup startup policy, defaults, and resolution sources. -- [x] Enumerate every effect: worktree, setup, agent terminal, setup terminal, each configured - terminal pane, and dispatch input; include exact tab/leaf identity when available. -- [x] Persist accepted dispatch input atomically with the ready transition so later setup refreshes - cannot erase it. -- [x] Tag every terminal effect with role and created/reused action. -- [x] Report setup as running only after its exact PTY spawn receipt is durable. -- [x] List every residual resource on failure or unknown outcome. -- [x] Never claim an effect was created before it exists. -- [x] Do not add a background provisioning executor; intentionally launched setup may continue as - its receipt states. - -### Dispatch and Task state machine - -- [x] Implement starting, ready, start-unknown, failed, succeeded, stopping, stop-unknown, stopped, - and abandoned Dispatch states. -- [x] Block the Task while start/stop outcome remains unknown. -- [x] Allow semantic `--retry-of` only from explicit failed, stopped, abandoned, or proven no-effect - states. -- [x] Require the replacement to repeat its intended placement and agent/terminal choice; do not - silently inherit a prior attempt's topology. -- [x] Reject unsafe retry without mutation. -- [x] Completed Tasks require a follow-up Task rather than retry. - -### Show, read, stop, and abandon - -- [x] Route operations by Dispatch ID after start; do not require resource IDs again. -- [x] Implement V1 `worker-read` as a thin route to bounded terminal-read. -- [x] Preserve cursor, limit, terminal status, and limited/truncated fields. -- [x] Stop fences lifecycle and blocks the Task in one home-side compare-and-set. -- [x] Stop affects only the supervised agent terminal/process. -- [x] Never delete the worktree, setup terminal, configured tabs, or unrelated processes. -- [x] Return stopped, already-settled, failed, and stop-unknown receipts truthfully. -- [x] Abandon performs no remote/process action, retains possibly-live resources, and enables a - warned replacement. - -### Same-server recovery tests - -- [x] Current, existing, child, top-level, explicit-terminal, and configured-tab starts pass. -- [x] Setup run/skip/inherit and start-immediately/wait-for-setup combinations pass. -- [x] Trust/update prompt, setup failure, terminal failure, and task-input failure receipts pass. -- [x] Crash before effect, after possible effect/before receipt, and after durable receipt are - distinguishable as failed/no-residual, outcome-unknown, and failed-with-residual respectively. -- [x] Stop/completion races preserve the first committed terminal transition. -- [x] Restart never adopts a same-looking pane or process incarnation. - -## Phase 3 — Connected Orca server federation - -### Placement and identity - -- [x] Add worker-only `--on ` without changing global `--environment` meaning. -- [x] Default worker placement to the Run home. -- [x] Require `--on` for remote existing worktree/terminal selectors in V1. -- [x] Resolve remote resources through explicit read-only discovery; never guess by name/path. -- [x] Return `server_required`, `worktree_not_found_on_server`, and - `terminal_worktree_mismatch` before related worker effects; treat a mismatched remote - Dispatch/home receipt as `resource_server_mismatch` and never adopt it. -- [x] Pin each remote Dispatch to the authenticated worker-server public-key fingerprint. -- [x] Store runtime ID only as a process epoch, never durable server identity. -- [x] Return `peer_changed` with no effect if a saved environment is re-paired to a different server. -- [x] Preserve a routing tombstone when an environment with nonterminal Dispatches is removed. - -### Remote Dispatch attachment - -- [x] Persist a narrow attachment on the worker server before task input. -- [x] Store home peer identity, Dispatch capability verifier, stable pane/process incarnation, - resource receipts, protocol version, and relay cursors. -- [x] Do not copy the Run DAG/database to the worker server. -- [x] Protect attachment credentials/database/WAL/SHM as current-user-only on macOS, Linux, and - Windows. - -### Bidirectional relay - -- [x] Use the existing authenticated saved-environment connection; require no public callback or - reciprocal pairing. -- [x] Run a Run-home subscription/pull service for active remote Dispatches. -- [x] Persist worker-to-home lifecycle/questions until home import acknowledgment. -- [x] Persist home-to-worker replies/control mail until worker import acknowledgment. -- [x] Route coordinator `send --to dispatch:` through that same durable relay and wake the - exact remote worker's local `check --wait`. -- [x] Key relay items by pinned peer, Dispatch ID, direction, monotonic sequence, and a - 128-bit-or-stronger message ID. -- [x] Import only contiguous source sequences; buffer/reject gaps. -- [x] Acknowledge only the highest contiguous committed sequence. -- [x] Assign ordinary Run-mailbox order only at home import. -- [x] Apply lifecycle transition and message import in one transaction before acknowledgment. -- [x] Enforce per-message and per-Dispatch count/byte quotas. -- [x] Coalesce heartbeats and reserve room for one terminal lifecycle report. -- [x] Return `relay_quota_exceeded`; do not add a dead-letter system. - -### Federated control and recovery - -- [x] Route show/read/stop/retry by Dispatch receipt; agents do not repeat `--on`. -- [x] Forward the same application retry request ID across home and worker server. -- [x] Return typed unknown outcome with last durable stage and exact next commands. -- [x] Reconcile a lost federated stop response from a later authoritative stopped receipt. -- [x] Treat abandonment of a superseded Dispatch as a no-op for the replacement Task. -- [x] Preserve and relay post-return federated setup evidence without changing worker lifecycle. -- [x] Recreate active relay subscriptions after Run-home restart. -- [x] Preserve worker attachment and relay state after worker-server restart. -- [x] Report running only when pane and process incarnation match after restart. -- [x] One disconnected worker server must not block local or other-server inbox delivery. -- [x] No automatic worker replacement on disconnect or silence. - -### Capability negotiation - -- [x] Advertise one aggregate `orchestrationFederationV1` control-plane capability. -- [x] Pin peer fingerprint and protocol version in the durable operation record. -- [x] Revalidate them inside the worker-side mutation, not only in a preflight probe. -- [x] Return `capability_unsupported` before Dispatch/resource/prompt effects. -- [x] Keep host/Git/setup validation inside existing primitives rather than a generalized capability - matrix. - -### Federation scenario matrix - -- [x] Post-rebase physical Mac Run home -> Windows worker preserves exact process identity through - renderer adoption, routed read, heartbeat, question/reply, completion, and stop. -- [x] Mac Run home -> Windows worker: start, completion, failure, question/reply, read, and stop. -- [x] Windows Run home -> Mac worker: the same flows through a saved Mac pairing. -- [x] Native, WSL, SSH, and relay-backed execution-host paths preserve ownership and CLI capability. -- [x] Run home restarts alone; worker server restarts alone; both restart. -- [x] Disconnect before send proves no effect. -- [x] Disconnect after possible acceptance returns unknown and deduplicates exact retry. -- [x] Duplicate and reordered relay frames/acknowledgments converge without loss or duplication. -- [x] Re-pair/key change cannot retarget an active Dispatch. -- [x] Same-looking handles/resources on two servers never cross-route. -- [x] Mixed server versions fail before effects. -- [x] Windows PowerShell quoting, Windows paths, WSL environment propagation, and SSH bridge - allowlists pass. - -## Phase 4 — Structured worker output - -- [x] Reuse Orca's exact pane/process-to-provider-session association; do not create a second status - system. -- [x] Keep bounded terminal-read as the universal fallback. -- [x] Read only Codex, Claude/OpenClaude, and Grok transcripts supported by the existing - Native Chat decoders. -- [x] Never guess the latest session by current working directory, terminal title, logo, or agent - type. -- [x] Pin Dispatch, process, source, and provider session for the full opaque cursor chain. -- [x] Preserve the existing structured native-chat message/block representation and emit bounded - parsing/clipping warnings. -- [x] Label terminal fallback and its reason explicitly. -- [x] Read transcripts on the worker-owning server and never serialize their filesystem paths. -- [x] Fall back to the legacy federated terminal-read RPC when a connected server lacks the additive - structured-read method. -- [x] Cover exact selection, sibling-session isolation, source changes, malformed input, limits, - path privacy, CLI rendering, and mixed-version fallback with automated tests. -- [x] Physically verify local Codex, two same-worktree Codex sessions, cursor continuation, - provider-session replacement, explicit terminal selection, and safe Run-home restart behavior. -- [x] Physically verify Mac Run home -> older Windows worker terminal fallback, including an opaque - continuation cursor and explicit transcript-required failure. -- [ ] Physically verify hooks-disabled automatic fallback and disconnect/reconnect. -- [ ] Physically verify exact structured Mac-to-Windows and Windows-to-Mac reads after both worker - servers run the new additive method. -- [x] Do not add resume, live-stream control, session exclusivity, or a universal transcript ontology. - -## Migration — Hard cutover from pre-Run orchestration - -### Contract and effect fence - -- [x] Add one orchestration contract version and one advertised runtime capability without changing - the global runtime protocol. -- [x] Keep one shared mutation/read classifier for CLI, runtime dispatch, durable receipts, and - connected-server calls. -- [x] Require the contract before parameter parsing, mutation receipts, database writes, prompt - injection, process actions, or connected-server mutations. -- [x] Preflight local and paired runtime capabilities before a new CLI sends a mutation. -- [x] Carry the contract through native Unix/named-pipe, WebSocket, and connected-server envelopes. -- [x] Retire `coordinator-start`, `coordinator-stop`, `run`, and `run-stop` before RPC effects. -- [x] Do not add a compatibility executor, automatic rewrite, legacy scheduler, or in-flight drain. - -### Agent recovery and legacy inspection - -- [x] Return `effectsApplied=false`, structured guide metadata, and executable argument-only - `skills get orchestration --full` recovery. -- [x] Attach the same guide recovery to no-bound-Run and missing worker outcome errors. -- [x] Preserve explicit read-only Run, task, inbox, Dispatch, gate, and terminal inspection. -- [x] Allow `task-list --run run_legacy_local` without binding the legacy Run. -- [x] Keep default/actionable check and acknowledgment fenced; only explicit peek/all history reads - may inspect legacy mail. -- [x] Document that active pre-upgrade agents keep running as processes but are unsupervised and - must be inspected before replacement. -- [x] Remove the legacy scheduler recipe from the version-matched full orchestration guide. - -### Migration acceptance - -- [x] Missing/wrong contract rejects every classified mutation before parsing, receipt, and effect. -- [x] Current-contract mutations still execute and retain durable retry receipts. -- [x] Read-only inspection works without a contract and does not consume legacy data. -- [x] Local and remote clients reject a runtime missing the contract capability before mutation. -- [x] Native and encrypted WebSocket transports preserve the contract field. -- [x] Old `worker_done` leaves message, Task, and Dispatch state unchanged. -- [x] Human and JSON errors preserve no-effects and guide-reload recovery. -- [x] `skills get orchestration --full` remains runtime-independent and generated guides stay in - sync. -- [ ] Branch-head CI passes after the verified migration commit is pushed. Local orchestration, - repository tests, typechecks, reliability gates, and production builds pass. - -## Cross-cutting quality gates - -### Persistence and transactions - -- [x] Define process-crash durability separately from sudden-power-loss durability. -- [x] Keep SQLite WAL + `synchronous=NORMAL` for the documented process-crash guarantee; require a - separate policy change before promising sudden-power-loss durability. -- [x] Keep lifecycle import, terminal transitions, and acknowledgment transaction boundaries explicit. -- [x] Exercise migrations from existing task/message/dispatch/scheduler-run data. - -### Cross-platform - -- [x] Native macOS, Linux, and Windows tests cover each new CLI/RPC contract. -- [x] WSL and SSH host identity/capability state is scoped to the actual execution host. -- [x] Paths use platform utilities; examples are PowerShell/cmd/POSIX safe. -- [x] Named-pipe, Unix-socket, WebSocket, WSL, and SSH bridges carry Dispatch capabilities safely. - -### Documentation - -- [x] CLI help owns exact flags, selectors, defaults, outcome fields, and exit-code behavior; typed - RPC errors remain the machine-readable error contract. -- [x] The skill owns short decision recipes and common misuses, not protocol internals. -- [x] Every shipped phase updates this checklist and adds a progress-log entry. -- [x] The ignored HTML proposal and this tracked checklist remain semantically synchronized. - -## Findings and decision log - -### 2026-07-22 — Phase 2 closure without option-surface creep - -- `worker-start` passes exact repository, base, child/top-level lineage, display/comment metadata, - and setup choices into the existing worktree primitive. It does not duplicate `worktree create`'s - project/host convenience resolver: `--on` already names the connected Orca server and `--repo` - names the repository on that server. -- A gated setup receipt becomes `succeeded` only after the agent wrapper proves setup completed. A - confirmed spawn/script failure fails before task input; timeout keeps `running` because silence is - not failure. -- The existing single durable worker row is the operation stage journal. A pre-effect failure has no - residuals, possible acceptance before receipt is unknown, and later failure after a durable effect - lists exact residual resources. No background saga executor or general effect engine was added. -- This earlier Phase 4 deferral was based on an incomplete audit. Orca already retained an exact - pane-scoped provider-session association from agent hooks; the narrow implementation now exposes - it to the worker-owning runtime and still falls back when that evidence is absent. - -### 2026-07-22 — Final setup/startup review - -- Keep setup-run as the new-worktree orchestration default. -- Preserve Orca's existing `start-immediately` default: setup and agent run side by side. -- Only explicit `wait-for-setup` gates agent launch/task delivery. -- A custom-argv two-step terminal launch cannot preserve wait-for-setup and must not silently bypass - it. -- Receipts must enumerate role-tagged agent, setup, and configured terminals; a boolean - `setupSpawned` is insufficient. -- Setup outcome never gates readiness under start-immediately, regardless of observation timing. - -### 2026-07-22 — Federation robustness review - -- Multi-server operation is a core requirement, not a later optional product feature. -- Use a single authoritative Run home with narrow remote Dispatch attachments and bidirectional - relay; do not replicate the Run database. -- Pin active Dispatches to authenticated peer identity so re-pairing cannot redirect work. -- Use contiguous, scoped relay sequences and bounded storage. -- Hide peer fingerprints, relay cursors, process incarnations, and capabilities from normal agents. - -### 2026-07-22 — Validation and scope boundary - -- Phase 0 and Phase 1 are complete: their command, recipe, Run, inbox, lifecycle, question, - authority, and mutation-ledger acceptance rows now have focused passing tests. -- Phase 2 remains open until the full existing-worktree/explicit-terminal/setup-policy/failure-stage - matrix is covered. Passing current/new-worktree and recovery slices are not enough to claim it. -- Phase 3 remains open until the named Mac/Windows, WSL, SSH, relay, restart, disconnect, and quoting - matrix runs on those actual paths. The in-process federation harness proves protocol behavior but - is not a substitute for cross-platform acceptance. - - At this point Phase 4 stayed deferred pending proof of an exact association. The later - structured-output audit found the existing pane-scoped hook association and superseded this - decision without adding a universal provider framework. - -### 2026-07-21 — Simplification decision - -- Replace the original broad orchestration redesign with four public concepts: Run, Task, Dispatch, - and Message. -- Keep agent-owned strategy and strong control-plane primitives. -- Remove UI, scheduler, capacity allocation, access enforcement, commit/integration tracking, - generalized provider/session abstractions, and other speculative product machinery. -- Retain Run because it provides a durable namespace and home mailbox across connected servers, not - because it schedules work. - -## Progress log - -Append new entries chronologically. Do not rewrite older entries except to correct factual errors. - -### 2026-07-22 — Checklist initialized - -- Changes: - - Created this tracked implementation ledger from the reviewed orchestration proposal. - - Recorded all phases, acceptance tests, non-goals, and review-derived invariants. - - Updated the current orchestration skill to prefer setup-run, preserve start-immediately, process - message batches, prefer `agentTerminalHandle`, and reject custom-argv wait-policy bypass. -- Files: - - `ORCHESTRATION_IMPLEMENTATION_CHECKLIST.md` - - `skills/orchestration/SKILL.md` - - `docs/orchestration-primitives.html` (ignored design source) -- Verification: - - HTML parsed successfully with balanced tags and unique IDs. - - Final review Task completed without an architectural blocker. -- Findings: - - Implementation may begin with Phase 0. - - Phase 2 readiness/receipt work depends on the explicit setup and role-tagged-effect contracts - recorded above. -- Next: - - Finish Phase 0 command compatibility and version-matched recipes. - -### 2026-07-22 — Phase 0 command safety and vocabulary - -- Changes: - - Renamed the scheduler-like command surface to `coordinator-start` and `coordinator-stop` while - retaining `run` and `run-stop` as documented deprecated aliases. - - Updated root help and both orchestration skill sources to distinguish the legacy automatic loop - from the proposed lightweight Run namespace and to prefer the explicit task/dispatch/wait loop. - - Made `orchestration reset` require exactly one of `--all`, `--tasks`, or `--messages` before it - contacts the runtime. - - Synchronized setup, worker-terminal selection, and message-batch guidance into the canonical - guide and regenerated the bundled CLI guide. -- Files: - - `src/cli/specs/orchestration.ts` - - `src/cli/handlers/orchestration.ts` - - `src/cli/help.ts` - - `src/cli/handlers/orchestration.test.ts` - - `src/cli/index.test.ts` - - `src/main/runtime/orchestration-cli-subprocess.test.ts` - - `skill-guides/orchestration.md` - - `skills/orchestration/SKILL.md` - - `src/cli/bundled-skill-guides.ts` -- Verification: - - `pnpm vitest run --config config/vitest.config.ts src/cli/index.test.ts src/cli/handlers/orchestration.test.ts` — 199 tests passed. - - `pnpm verify:bundled-skill-guides` — passed. - - `pnpm typecheck:cli` — passed. - - `git diff --check` — passed. -- Findings: - - Keeping hidden compatibility aliases preserves existing scripts without advertising the old - scheduler noun as the normal agent path. - - Truthful success/failure recipes depend on the Phase 1 explicit lifecycle outcome; do not - document the current behavior as if a failed `worker_done` failed the Task. -- Next: - - Implement explicit succeeded/failed worker-report semantics and then finish the version-matched - Phase 0 recipes without lying about failure behavior. - -### 2026-07-22 — Truthful worker terminal outcomes - -- Changes: - - Added the structured `--outcome succeeded|failed` worker-report field to local and SSH fallback - CLI payload construction and injected preambles. - - Added one transactional compare-and-set that settles the Dispatch and Task together, promotes - dependents only on success, and replays an identical terminal outcome idempotently. - - Persisted worker result provenance, message identity, summary, files, and report path as a - labeled `worker_report` rather than an Orca-verified result. - - Converted missing, invalid, unknown, stale, mismatched, inactive, and foreign reports into - typed, high-priority audit rows without mutating lifecycle state. - - Updated the legacy automatic coordinator loop to record failed worker reports as failed tasks. -- Files: - - `src/cli/specs/orchestration.ts` - - `src/cli/handlers/orchestration.ts` - - `src/main/ssh/ssh-remote-orchestration-send.ts` - - `src/main/runtime/orchestration/types.ts` - - `src/main/runtime/orchestration/db.ts` - - `src/main/runtime/orchestration/lifecycle-reconciliation.ts` - - `src/main/runtime/orchestration/preamble.ts` - - `src/main/runtime/orchestration/coordinator.ts` - - Corresponding CLI, SSH, preamble, DB lifecycle, coordinator, and RPC tests/snapshots - - Both orchestration skill sources and the generated bundled guide -- Verification: - - Five focused CLI/lifecycle/preamble/coordinator/SSH test files — 124 tests passed. - - `src/main/runtime/rpc/methods/orchestration.test.ts` — 114 tests passed. - - `pnpm typecheck:node` — passed. - - `pnpm typecheck:cli` — passed. - - `pnpm verify:bundled-skill-guides` and `git diff --check` — passed. -- Findings: - - The old subject-based failure convention was not merely confusing: it irreversibly completed a - failed Task. Requiring a tiny enum is a robust primitive, not workflow policy. - - Stop and abandon still need to share this terminal-transition fence before the broader - first-writer-wins checklist item can be marked complete. -- Next: - - Add the lightweight Run schema and explicit coordinator binding, then key new Task/Dispatch/ - Message state to that Run without changing agent placement policy. - -### 2026-07-22 — Lightweight Run foundation and inbox-only mail - -- Changes: - - Added schema v7 with lightweight Runs, stable explicit pane binding, consumer generations, and - an inspect-only legacy Run for all migrated pre-Run rows. - - Kept legacy automatic coordinator-loop storage in its existing `coordinator_runs` table. - - Added `run-create`, `run-use`, `run-current`, `run-list`, and `run-show` across CLI/RPC, with - explicit binding and no worktree or sole-candidate inference. - - Scoped new Task creation/list/update/dispatch operations to an explicit or currently bound Run; - Dispatches and decision gates inherit their Task's Run. - - Removed structured-mail prompt injection from send and ask.

lifecycle sends from an active Dispatch - now default to its Run and no longer require agents to carry a coordinator terminal handle. - - Added schema v8 Deliveries: one FIFO batch of at most 50 rows, one outstanding batch per Run, - exact replay until whole-batch acknowledgment, and consumer-generation fencing. - - Made `check --ack --wait` perform ack, check, and waiter registration without an - intervening async gap; type filters are wake predicates and never split the FIFO batch. - - Added typed timeout, cancellation/connection-loss, second-waiter, stale-Delivery, and fenced- - consumer outcomes, plus persisted Delivery replay after an Orca database reopen. - - Added schema v9 question threads keyed by the original message ID, with active-Dispatch Run - defaulting, timeout-safe resume, current-consumer first-answer authority, idempotent replay, and - conflicting-answer rejection. - - Updated injected worker guidance and the orchestration skill so normal lifecycle and question - commands omit internal Run/server identity and coordinators explicitly process/ack each batch. -- Files: - - `src/main/runtime/orchestration/types.ts` - - `src/main/runtime/orchestration/db.ts` - - `src/main/runtime/orca-runtime.ts` - - `src/main/runtime/rpc/methods/orchestration.ts` - - `src/main/runtime/rpc/methods/orchestration-runs.ts` - - `src/main/runtime/orchestration/preamble.ts` - - CLI specs/handlers, RPC error mapping, skill sources, snapshots, and focused tests -- Verification: - - DB/RPC/runtime/CLI/preamble focused suite — 1,190 tests passed after the expected preamble - snapshot update. - - Delivery tests cover 50-row bounds, FIFO replay, idempotent ack, filter wake semantics, - consumer fencing, and reopen recovery. - - Question tests cover create/answer, same-answer replay, answer conflict, timeout persistence, - resume, unrelated wakes, and Dispatch closure storage behavior. -- Findings: - - A Run inbox needs only one durable Delivery row plus immutable message IDs; no dead-letter, - selective NACK, or second Event subsystem is necessary. - - Question answers belong in thread state rather than inbox-read state, so replying never - accidentally acknowledges the coordinator's whole Delivery. -- Next: - - Replace caller-supplied pane claims with a narrow Dispatch capability and add the durable - mutation ledger needed to recover unknown acceptance without replaying effects. - -### 2026-07-22 — Narrow Dispatch lifecycle capability - -- Changes: - - Minted a 256-bit per-Dispatch secret for injected workers while persisting only its SHA-256 - verifier. - - Bound lifecycle/question authority to the exact runtime-observed pane and PTY process - incarnation in addition to the Dispatch ID. - - Carried the secret in the authenticated RPC envelope across local socket, WebSocket, - shared remote-runtime, and SSH fallback transports rather than orchestration payload fields. - - Revoked the capability when worker completion/failure settles the Dispatch and stopped trusting - caller-supplied pane metadata in the SSH fallback. -- Files: - - `src/main/runtime/orchestration/db.ts` - - `src/main/runtime/orchestration/types.ts` - - `src/main/runtime/orchestration/preamble.ts` - - `src/main/runtime/rpc/core.ts` - - `src/main/runtime/rpc/dispatcher.ts` - - `src/main/runtime/rpc/methods/orchestration.ts` - - CLI and remote transport implementations plus focused tests -- Verification: - - Ten focused DB/RPC/runtime/CLI/SSH files — 1,238 tests passed. - - Capability cases cover missing token, wrong token, wrong pane, changed process incarnation, - success, and post-settlement revocation. - - `pnpm typecheck:node` and `pnpm typecheck:cli` — passed. -- Findings: - - Terminal handles and environment-provided pane strings are useful routing metadata but are not - lifecycle authority. - - Stop, abandon, and replacement must use the same revocation fence before that remaining - checklist item can be completed. -- Next: - - Add the durable mutation ledger and use it to recover unknown acceptance without repeating - external effects. - -### 2026-07-22 — Durable mutation receipts - -- Changes: - - Added schema v11 mutation receipts keyed by an authenticated-caller fingerprint and opaque - request ID, with canonical payload hashing and pending/completed state. - - Replayed completed results across retries and restart, joined concurrent identical mutations, - rejected changed input as `request_mismatch`, and surfaced orphaned pending work as - `operation_unknown`. - - Added request IDs to local socket, named-pipe, WebSocket, saved-environment, and SSH fallback - envelopes;

future worker start/stop must instead return and preserve typed unknown outcomes - around external effects. - - The ledger infrastructure covers every existing V1 mutation; worker start/stop/abandon will be - added to the same policy when those commands exist. -- Next: - - Implement the same-server worker lifecycle and its first-writer-wins stop/abandon fence. - -### 2026-07-22 — Same-server worker lifecycle foundation - -- Changes: - - Added schema v12 composed-worker state and created the starting Dispatch plus Task transition - before terminal effects. - - Added synchronous `worker-start` for the current or an exact existing worktree, with fresh-agent - default, explicit-terminal reuse, TUI readiness, capability attachment, lifecycle injection, and - honest failed receipts with residual resources. - - Added Dispatch-routed `worker-show` and bounded `worker-read`. - - Added first-writer-wins `worker-stop` and `worker-abandon`;

current/existing workers are the verified slice. -- Next: - - Add agent-first child/top-level creation with setup-run default and startup-policy receipts, then - extend the same Dispatch routing across connected Orca servers. - -### 2026-07-22 — Agent-first new-worktree workers and setup receipts - -- Changes: - - Added child and top-level agent-first worktree creation to `worker-start`, reusing the exact - startup agent terminal and listing setup/configured terminals as role-tagged effects. - - Made omitted setup resolve to `run`, preserved explicit run/skip/inherit and repository startup - policy, and returned `not_configured` when no setup hook exists. - - Kept `start-immediately` setup non-gating, persisted later setup success/failure, and emitted a - typed Run notice without changing a ready worker's lifecycle state. - - Narrowed setup receipts to callers that explicitly await terminal provisioning so ordinary - worktree creation does not report renderer-delegated setup as a false spawn failure. - - Added typed unknown-start recovery when worktree creation may have been accepted before a - connection failure. -- Files: - - `src/main/runtime/orca-runtime.ts` - - `src/main/runtime/rpc/methods/orchestration-workers.ts` - - `src/main/runtime/rpc/methods/orchestration-workers-new-worktree.test.ts` - - `src/main/runtime/rpc/methods/orchestration.test.ts` - - `src/shared/types.ts` -- Verification: - - New-worktree worker scenarios — 8 tests passed. - - Worker RPC plus runtime worktree suites — 911 tests passed. - - `pnpm typecheck:node` — passed. -- Findings: - - A setup status is only truthful after the supervised caller awaits the runtime's terminal - provisioning result; normal renderer-delegated creation should retain its existing launch - payload instead. - - The generic mutation receipt and starting Dispatch are still separate commits, so atomic start - acceptance and crash-boundary reconciliation remain open. -- Next: - - Make worker-start acceptance one transaction, then add restart reconciliation that never adopts - a same-looking pane or process. - -### 2026-07-22 — Atomic worker acceptance and conservative restart recovery - -- Changes: - - Moved the worker-start retry request insertion into the same SQLite transaction that creates the - starting Dispatch and moves its Task to dispatched. - - Added a process runtime epoch to composed Dispatches so interrupted starts/stops become explicit - unknown outcomes after restart instead of remaining indefinitely in transitional states. - - Made worker show/read/stop verify the persisted stable pane plus exact PTY process incarnation; - a same-looking replacement is reported as changed and is never read or closed. - - Restricted semantic retry to the Task's latest failed, stopped, or abandoned Dispatch. -- Files: - - `src/main/runtime/orchestration/db.ts` - - `src/main/runtime/orchestration/types.ts` - - `src/main/runtime/rpc/core.ts` - - `src/main/runtime/rpc/dispatcher.ts` - - `src/main/runtime/rpc/errors.ts` - - `src/main/runtime/rpc/methods/orchestration-workers.ts` - - Focused DB, mutation-ledger, new-worktree, and recovery tests -- Verification: - - Atomic acceptance and recovery suite — 231 tests passed. - - Follow-up DB/recovery/new-worktree suite — 93 tests passed. - - `pnpm typecheck:node` — passed. -- Findings: - - Runtime ID is useful only as a process epoch. It is not a durable server identity and must not be - used to route federated Dispatches. - - After restart, preserving uncertainty is safer than adopting a restored pane: the prior worker - may still exist, but only explicit stop/abandon/retry recovery may replace it. -- Next: - - Audit and close the remaining same-server acceptance rows, then implement saved-environment - placement and the narrow federated Dispatch attachment. - -### 2026-07-22 — Connected-server federation and crash-safe relay - -- Changes: - - Added worker-only `--on ` placement while keeping Run/Task authority on the - current server and routing later show/read/stop operations solely by Dispatch ID. - - Pinned remote Dispatches to the saved server public-key fingerprint and stored runtime identity - only as a replaceable process epoch; re-pairing returns `peer_changed` before effects. - - Added a narrow worker-server attachment with protocol version, capability verifier, exact - pane/process identity, effects, setup state, and bidirectional relay cursors—without copying the - Run DAG. - - Added durable worker-to-home lifecycle/question relay and home-to-worker reply relay with - contiguous sequence checks, source acknowledgment, quotas, heartbeat coalescing, and reserved - terminal-report capacity. - - Made home import commit the message, question/lifecycle transition, and source cursor in one - transaction before acknowledgment. - - Added federated show/read/stop, stop/completion ordering, timeout/resume after worker restart, - relay restart, exact-process checks, ack-loss replay, gap rejection, peer-change fencing, and - POSIX database/WAL/SHM permission coverage.

Remaining unchecked rows are the real connected-platform Phase 3 matrix - and cross-platform transport evidence. -- Next: - - Exercise federation disconnect/reorder/restart semantics, then run branch-head Mac/Windows - acceptance without replacing either production Orca runtime. - -### 2026-07-22 — Native Mac-to-Windows acceptance gaps - -- Changes: - - Built and launched branch-head Mac and Windows servers on isolated profiles and paired them over - the existing authenticated WebSocket transport. - - Used a temporary, exact Tailscale TCP proxy because Windows Firewall correctly blocked the new - test-binary port; production Orca and firewall policy were left unchanged. - - Added explicit dev-CLI provenance so custom profile paths still generate `orca-dev` worker - commands. - - Increased only the Windows ConPTY bracketed-paste render gap before Enter from 500 ms to 1.5 s. -- Files: - - `config/scripts/orca-dev.mjs` - - `src/cli/handlers/orchestration.ts` - - `src/shared/agent-prompt-injection.ts` - - Focused wrapper, CLI, and prompt-injection tests -- Verification: - - Native Windows discovery, exact worktree routing, pre-effect failure, retry, ready receipt, - worker-read, and remote worker-stop all returned truthful branch-head receipts. - - Focused dev-provenance and prompt-injection suite: 160 tests passed. -- Findings: - - A fresh Windows agent profile surfaces trust/login/update prompts as typed `agent_readiness` - failures with residual terminals, as designed. - - The first authenticated Windows worker proved that 500 ms could leave a long preamble in the - Codex input buffer, and that a custom dev profile could incorrectly call the production CLI. - - Phase 3 remains open until the fixes are rebuilt on Windows and the full completion/question/ - failure/restart matrix succeeds without a manual Enter or CLI substitution. -- Next: - - Rebuild both branch servers with these fixes and repeat the real Mac-home to Windows-worker flow. - -### 2026-07-22 — Headless Windows dev-worker CLI routing - -- Changes: - - Made every `orca-dev` entry path install profile-scoped `orca-dev` and `orca` terminal wrappers, - including Windows `.cmd` wrappers and headless `orca-dev serve`. - - Kept the wrapper generation shared with the Electron dev runner so interactive and headless dev - servers expose the same exact CLI and user-data profile to worker terminals. -- Files: - - `config/scripts/dev-cli-terminal-wrapper.mjs` - - `config/scripts/orca-dev.mjs` - - `config/scripts/run-electron-vite-dev.mjs` - - Focused cross-platform wrapper tests -- Verification: - - Wrapper, CLI provenance, dev-runner, preamble, and orchestration handler suites: 55 tests passed. - - Focused oxlint and formatting checks passed. -- Findings: - - The rebuilt prompt submitted automatically on Windows, but the worker then found no - profile-scoped `orca-dev` command because headless serve bypassed the Electron dev runner and the - runner itself had never written Windows wrappers into the PATH directory used by Orca terminals. - - This is a dev/acceptance launcher defect, not a new federation primitive or production routing - requirement. -- Next: - - Rebuild and restart the Windows branch server, then repeat the same Dispatch and require an - automatically relayed `worker_done` before checking any federation acceptance row. - -### 2026-07-22 — Mac-home to Windows-worker federation accepted - -- Changes: - - Fast-forwarded and restarted the isolated Windows branch server with the profile-scoped wrapper - fix while preserving its authenticated server key and saved-environment binding. - - Exercised separate success, intentional failure, and blocking question/reply Dispatches from the - isolated Mac Run home to native Windows Codex workers. -- Files: - - `ORCHESTRATION_IMPLEMENTATION_CHECKLIST.md` -- Verification: - - Success `ctx_f982ddb1bdf9` submitted without manual input, relayed `worker_done`, and atomically - settled its Task/Dispatch as completed/succeeded. - - Failure `ctx_5f28665cf04a` relayed `outcome=failed` and atomically settled its Task/Dispatch as - failed without treating failure prose as success. - - Question `ctx_4aec24c47e30` relayed a typed question to the Mac Delivery, carried the `blue` reply - back to the blocked Windows ask, then relayed a successful terminal report. - - Routed bounded read and exact-agent stop were also exercised against Windows Dispatch receipts; - stop closed only the accepted agent terminal. -- Findings: - - Windows ConPTY prompt submission, profile-specific CLI selection, authenticated lifecycle - acceptance, contiguous bidirectional relay, whole-batch acknowledgment, and terminal-state - reconciliation now pass together in the real Mac-to-Windows path. - - This completes only the named Mac-home to Windows-worker row; reverse direction, restart with an - active Dispatch, disconnect/unknown-outcome, WSL/SSH/relay-host, and transport coverage remain - open. -- Next: - - Pair the isolated Mac server into the Windows test profile and run the same acceptance flow with - Windows as the Run home. - -### 2026-07-22 — Windows-home to Mac-worker federation accepted - -- Changes: - - Added a reciprocal saved Mac environment to the isolated Windows profile without exposing its - pairing credential in terminal history. - - Exercised separate success, intentional failure, blocking question/reply, bounded read, and exact - stop Dispatches with Windows as Run home and native macOS as worker server. - - Made worker observations report `exited` for the exact disconnected terminal instead of - misleadingly projecting `running`;

the observation regression suites pass 36 tests. -- Findings: - - One reciprocal pairing is sufficient for a Windows-owned Run to route Mac worker control while - preserving a single Run database on Windows; no replicated scheduler or failover layer is needed. - - Stable process identity and live process status are separate facts. A disconnected terminal can - still be the exact historical worker, but it must not be labeled running or closed again. -- Next: - - Validate active-Dispatch restart/disconnect and exact-retry behavior, then exercise WSL/SSH/relay - execution-host propagation without broadening the federation protocol. - -### 2026-07-22 — Federated restart and pre-acceptance disconnect accepted - -- Changes: - - Restarted the Windows Run home alone, the macOS worker server alone, and both servers while each - had an active federated Dispatch. - - Stopped the macOS worker server before a Windows-home start request could be accepted. -- Files: - - `ORCHESTRATION_IMPLEMENTATION_CHECKLIST.md` -- Verification: - - Home-only restart preserved `ctx_f0693ff30c27`; `worker-show` found the same exact running macOS - worker under the unchanged worker epoch, and routed stop succeeded. - - Worker-only restart preserved `ctx_3bbb0142f9aa` at its Run home while the new macOS epoch - truthfully reported the missing terminal as non-exact; routed stop returned `stop_unknown` - without adopting or closing another process. - - Restarting both sides preserved `ctx_d46f68fa1400` and its attachment; inspection used the new - worker epoch, reported `missing` with `exactWorker=false`, and stop again returned - `stop_unknown` safely. - - With macOS already unreachable, retry request `disconnect-before-send-01` created neither a - Dispatch nor an attachment for `task_04fd0dc61065`; the Task remained ready. -- Findings: - - Durable home state and worker identity fencing survive independent epochs without requiring Run - replication or authority failover. - - A failed connection before remote acceptance is a clean no-effect result; it must not be - promoted to an ambiguous outcome or consume the Task. -- Next: - - Disconnect the worker route after possible acceptance, then follow the returned exact recovery - command and prove that retry deduplicates to one remote effect. - -### 2026-07-22 — Post-acceptance disconnect deduplicated - -- Changes: - - Cut the Windows Tailscale proxy while a Mac-home `worker-start` was provisioning remotely, then - restored the same route and replayed the exact application request ID. - - Allowed an explicit `worker-stop` to fence `start_unknown` locally and on the worker server; - exact pane/process observation still decides whether a terminal may actually be closed. -- Files: - - `src/main/runtime/orchestration/db.ts` - - `src/main/runtime/orchestration/orchestration-worker-dispatch-db.test.ts` - - `ORCHESTRATION_IMPLEMENTATION_CHECKLIST.md` -- Verification: - - The lost response left `task_bb86c87bdc60` attached to one pending Dispatch, - `ctx_6580d07d9006`, rather than creating a replacement. - - Replaying request `disconnect-after-start-01` returned the same Dispatch with - `state=outcome_unknown` and `mutation.replayed=true`. - - Remote inspection found one `disconnect-after-acceptance-01` worktree, one exact agent - terminal, and one expected setup terminal; no duplicate topology was created. - - Worker Dispatch DB, federated control, and recovery suites passed 29 tests; node typecheck and - focused oxlint passed. Branch-head CLI and Electron builds succeeded on macOS and Windows. - - Relay tests reject an out-of-order sequence without advancing the cursor, later accept the - missing and retried frames contiguously, treat the repeated frame as a duplicate, and preserve - exactly two messages. Lost-ack retry and mailbox delivery suites passed with it (24 tests). -- Findings: - - The acceptance run exposed one narrow recovery inconsistency: `worker-show` could prove an exact - worker existed while `worker-stop` rejected the durable `start_unknown` state. Explicit stop now - enters the same fenced stopping path from `ready` or `start_unknown`; unattached, missing, or - identity-changed workers still become `stop_unknown` without a process action. - - No scheduler, automatic retry, adoption, cleanup, or general distributed-operation framework is - needed for this recovery path. -- Next: - - Exercise duplicate/reordered relay convergence and the native/WSL/SSH transport matrix, then - synchronize the HTML proposal with the implemented contract. - -### 2026-07-22 — Cross-platform capability transport verified - -- Changes: - - Added an SSH compatibility-bridge test that carries the opaque Dispatch capability in the RPC - envelope and settles only the matching pane/process Dispatch. - - Added a composed worker-start test that binds the host-resolved `orca-ide` command and the - Dispatch capability into one WSL worker preamble. - - Updated the built-CLI reset fixture to recreate its required coordinator Run after a task reset. - - Updated the HTML recovery contract so explicit stop from `start_unknown` remains fenced and - process-identity checked. -- Files: - - `src/main/ssh/ssh-remote-orca-cli.test.ts` - - `src/main/runtime/rpc/methods/orchestration-workers-new-worktree.test.ts` - - `src/main/runtime/orchestration-cli-subprocess.test.ts` - - `docs/orchestration-primitives.html` (ignored design source) - - `ORCHESTRATION_IMPLEMENTATION_CHECKLIST.md` -- Verification: - - Native macOS Unix-socket worker control, native Windows named-pipe lifecycle reporting, and - bidirectional authenticated WebSocket federation passed in the real Mac/Windows matrix. - - On the real Windows host, the PowerShell/SSH launcher, SSH command allowlist, host passthrough, - WSL/native command selection, and multiline Windows quoting suites passed 31 tests; 13 - Unix-socket-only runtime-client tests correctly skipped on Windows. - - Platform-neutral SSH capability, WSL command selection, preamble, worker-start, and CLI envelope - suites passed 94 focused tests on macOS. - - The rebuilt CLI plus every orchestration, composed-worker, federation, and SSH regression file - passed together: 25 files and 456 tests.

The setup terminal remained present, the Dispatch - became stopped/failed, and the Task became blocked for explicit recovery. - - An unconfigured agent failed locally. A missing remote repo produced a typed failed Dispatch - with `effects=[]` and no residual resources. -- Findings: - - The first repeated failure was a stale Windows build artifact, not a failed fix: the source - checkout was at `b09c635ec` while `out/main/index.js` still had the old generation fence. - Relaunching the branch dev process produced a new runtime epoch and the fixed behavior. - - Omitted setup correctly resolved to Orca's `run` default. Its independent Windows install later - failed in `windows-native-registry`, but that did not delay task delivery and remained isolated - from exact agent stop. - - From an unmanaged shell, a coordinator mailbox check must name `--terminal`; a CLI running - inside the bound coordinator terminal continues to infer that identity normally. -- Next: - - Resolve only concrete findings from the independent ergonomics/federation re-review, run the - final local verification set, and reconcile PR review threads and CI. - -### 2026-07-24 — Post-dogfood recovery and ergonomics hardening - -- Changes: - - Made lost remote stop responses reconcilable and prevented stale Dispatch abandonment from - blocking an active replacement. - - Persisted setup completion as evidence only, preserving settled lifecycle state locally and - relaying the same outcome from a connected worker server. - - Rejected misleading explicit targets from federated workers and consumed `ask` answers exactly - once while retaining their durable thread record. - - Stored the accepted Dispatch in pending worker-start receipts so a post-restart retry returns the - exact inspection command. - - Rejected new-worktree placement for folder projects before effects. - - Restored the generated skill-history ledgers that the branch had accidentally truncated. -- Verification: - - The full orchestration DB/RPC/CLI/SSH regression selection passed 516 tests; its focused - recovery, setup, messaging, and mutation slice passed 239 tests. - - The earlier physical Mac-home to Windows-worker lifecycle covered ready/read/heartbeat, - ask/reply, completion, exact request replay, and exact stop. -- Findings: - - These were narrow truthfulness and recovery gaps; none required a scheduler, automatic retry, - access-control framework, replicated Run database, UI, or provider-session abstraction. - - The release-contract test failure is already present on `main`; it is separate from this - orchestration change.

However, coordinator mail addressed to that remote worker remained - queued at the Run home because only question replies used the home-to-worker relay. - - The injected worker's local `check --wait` also looked only for a same-server Dispatch, so even - an imported generic message could not wake it. -- Changes: - - Route stable `dispatch:` coordinator guidance through the existing per-Dispatch durable - relay; terminal-handle targeting remains a legacy/local path. - - Import control mail idempotently on the worker server, tolerate a replay after a lost import - acknowledgment, and wake only the exact attached worker process. - - Return a direction-aware relay receipt and teach CLI help, the versioned skill, and the - cross-server cookbook to use the Dispatch ID for follow-ups. -- Verification: - - Focused Node/CLI typechecks and 184 orchestration/federation/CLI tests passed before physical - revalidation. -- Next: - - Regenerate the bundled skill guide, re-review the narrow change, then repeat Windows-home to - Mac-worker follow-up, completion, exact transcript continuation, and disconnect/reconnect. - -### 2026-07-24 — Federated control-mail race hardening - -- Changes: - - Fence already-imported relay sequences before parsing or applying message side effects. - - Require the remote attachment to remain ready before accepting each new coordinator message. - - Recheck the Run-home worker state after importing worker lifecycle mail and do not push queued - guidance after the worker settles. - - Wake filtered worker waiters with the imported message's real type instead of always using - `status`. - - Negotiate a narrow control-mail capability and reject the send before queueing when an older - worker server supports base federation but not the new relay kind. -- Verification: - - Regression tests prove a replayed sequence with a different message ID creates no duplicate. - - A waiter registered before `worker_done` receives no stale control mail after completion, and a - direct late import is rejected as inactive. - - An imported escalation wakes an escalation-filtered waiter while a status-filtered waiter times - out normally. - - A new Run home connected to a prior worker build can still start the worker, but control mail - returns `capability_unsupported` and leaves no undeliverable relay row. - - The focused federation suites passed 24 tests; the broader orchestration/CLI selection passed - 475 tests. - - Full typecheck, lint, bundled-skill verification, CLI build, Electron/Vite build, - `git diff --check`, and the design-document reference-name audit passed. -- Findings: - - Relay ordering and worker settlement are control-plane guardrails, not agent policy: the - coordinator still chooses what to send and when. - - Terminal worker state is authoritative for delivery; queued guidance is retained at the Run - home but never injected into a completed worker. -- Next: - - Complete the final read-only review, then repeat the physical Windows-home to Mac-worker - follow-up, completion, exact transcript continuation, and disconnect/reconnect proof. - -### 2026-07-24 — Physical control-mail acceptance and dogfood fixes - -- Changes: - - Restarted the physical Windows runtime from branch head and confirmed both federation - capabilities before creating a fresh Windows-home Run. - - Fixed `check --ack --peek` so the exact Delivery is acknowledged before the - read-only history projection; the previous early return silently ignored `--ack`. - - Preserved the existing structured remote transport codes through the Run-home RPC boundary - instead of collapsing disconnect, timeout, and malformed-response failures to `runtime_error`. -- Verification: - - Run `run_074503e3edc6`, Task `task_8a07840e7aad`, and Dispatch `ctx_d6bac1ee6409` started a fresh - Codex worker in the existing Mac worktree with setup `not_applicable`. - - The worker relayed `ORCA_MAC_CONTROL_INITIAL_7C31`, blocked on its Dispatch inbox, received - coordinator guidance addressed to the stable Dispatch as `ORCA_MAC_CONTROL_FOLLOWUP_A842`, and - returned one authenticated successful `worker_done` containing both markers. - - The Windows home settled the Task and Dispatch once. `worker-read --source auto` returned - `source=transcript`, `provider=codex`, an opaque cursor, both markers, and no capability token or - transcript path. - - Removing the Mac listener left the Windows Task completed. Reconnecting with the wrong leftover - profile was rejected as unauthorized; reconnecting with the original profile preserved the - settled Dispatch and correctly returned `worker_identity_changed` for transcript reads after the - exact worker process was gone. - - The focused RPC suites passed 163 tests; formatting, diff checks, full typecheck, CLI build, and - desktop/web builds passed. - - After the Windows generated main bundle was verified at `8dd0d1b16`, Delivery - `delivery_888f972841d6` was acknowledged by `check --ack ... --peek`; the response echoed the - exact acknowledged ID and returned zero unread rows. - - With that build running, removing the Mac listener returned - `remote_runtime_unavailable` while the Task stayed completed. Reconnect preserved the succeeded - Dispatch, produced no duplicate Run mail, and returned `worker_identity_changed` rather than - attributing the old transcript to a replacement process. -- Findings: - - Delivery acknowledgment must compose with inspection modes explicitly; a successful command may - not silently ignore the acknowledgment effect. - - Remote transport already had narrow error codes. Preserving them is enough; no federation error - hierarchy or retry engine is needed. - - Saved peer identity fencing prevented accidental adoption of a server started from a different - profile.

The intended steady-state workflow is: + +- a feature developer adds a stable message ID and current English copy once; +- extraction discovers new and changed messages automatically; +- feature work does not wait for every target locale; +- translation automation processes only missing and stale units; +- humans review a small, risk-prioritized delta rather than whole catalogs; +- missing or stale translations safely fall back to current English; and +- deterministic, offline runtime bundles ship with the app. + +## Decision + +Use gettext PO as Orca's canonical bilingual translation source, under a +constrained profile: + +- `msgctxt` — the stable Orca message ID; +- `msgid` — the English source, current as of the entry's last + reconciliation; +- `msgstr` — the target translation; +- `#, fuzzy` — not approved for runtime, whether stale or newly + machine-translated; never compiled into runtime bundles; +- `#| msgid` — the prior English source associated with the retained + translation; +- `#.` — translator context and notes; +- `#:` — source references (optional, informational); and +- `#~` — retired entries, kept only under the retention policy below. + +Product source owns stable message IDs and current English defaults. Maintained +extraction produces the current English translation source. Each target locale +owns a sparse PO file containing only translations that exist, each carrying +the English source it is keyed against. + +Responsibilities are split so target catalogs never change in feature work: + +- **Feature PRs** change English only: source code, inline defaults, and the + extracted English source. +- **A read-only compiler** joins the current English source with each target + PO file by `msgctxt` and generates the existing i18next JSON bundle shape. + An entry whose stored `msgid` differs from current English is stale; one + whose `msgid` is current but fuzzy is pending approval. Both are omitted so + i18next falls back to current English. + The compiler never writes to PO files. Generated runtime JSON is disposable + and must not be hand-edited. +- **Post-merge localization automation** owns all PO mutations. Reconciliation + finds entries affected by merged English changes, updates `msgid` to current + English, preserves the old source in `#| msgid`, and sets `#, fuzzy` — so + translators and tools see the current source, the previous source, and the + prior translation in one unit. Reconciliation lands in localization-only + changes, never in the originating feature change. + +The reconciler — not gettext's own merge tooling — owns the join. `msgmerge` +keys entries on the `(msgctxt, msgid)` pair, so under stable IDs a source +change orphans the entry instead of marking it fuzzy. Reconciliation must join +by `msgctxt` alone. + +Absence of `#, fuzzy` means approved to ship, whether approval came from a +human or an explicitly configured low-risk automation policy. Machine or human +provenance is recorded separately in a documented comment or flag; it must not +be conflated with runtime eligibility. + +PO is an authoring and translation-workflow boundary, not a runtime +dependency. Orca must not require network access or a translation service to +display localized UI. + +## Why this solves the work problem + +The system is organized around translating only the delta: + +```text +feature change: stable ID + English + | + v + extraction and validation + | + v + missing/changed translation queue + | + v + machine translation + glossary/context + | + v + placeholder and policy validation + | + v + sparse locale bundle or English fallback +``` + +Feature developers do not synchronize target catalogs, copy English into +untranslated locales, run whole-catalog repair, or wait for translation +completion. A source change invalidates only the affected target units. +Unchanged translations remain byte-stable. + +The bilingual source gives the compiler enough information to distinguish: + +- **missing**: the locale has no entry for the ID; +- **stale**: the stored `msgid` differs from current English — true the + moment the English change merges, before any reconciliation runs; +- **pending approval**: the stored `msgid` is current, a target exists, and + `#, fuzzy` is set; and +- **current/approved**: the stored `msgid` is current, a target exists, and + `#, fuzzy` is absent. + +Missing, stale, and pending-approval entries are omitted from generated +target bundles so i18next uses current English. Staleness must not be inferred from Git history, +file timestamps, copied-English ratios, or a second hand-maintained database. + +## Constrained PO profile + +Orca will support only the subset needed for its message model. PR B must +define and validate that subset rather than accepting arbitrary PO documents. + +Each supported entry must carry: + +- one stable Orca message ID (`msgctxt`), unique within the file; +- the English source (`msgid`), current as of the entry's last + reconciliation; +- an optional target value (`msgstr`) in a target-locale file; +- translator notes or UI context when provided (`#.`); +- runtime workflow state (`#, fuzzy`), with provenance recorded in the + documented separate comment or flag; and +- the information needed to validate interpolation placeholders. + +Plurals use Orca's existing per-key convention: each i18next plural-suffixed +key (`…_one`, `…_other`) is its own PO entry. The profile must not use +`msgid_plural`/`msgstr[n]`, which would collide with i18next's own CLDR plural +selection and gettext's `nplurals` model. + +The compiler must reject: + +- duplicate or unstable IDs (including two entries sharing a `msgctxt`); +- empty targets represented as completed translations; +- unsupported states or constructs; +- malformed source/target entries; +- nondeterministic ordering or output — the profile must document exact + serialization normalization (entry order by `msgctxt`, fixed line folding, + LF endings, escaping rules) so every tool in the pipeline emits identical + bytes for identical content; and +- locale files whose declared language headers are incorrect. + +Placeholder validation is state-dependent (an entry is current only when its +stored `msgid` matches current English and it carries no fuzzy flag): + +- **stale or pending-approval entries**: a placeholder mismatch is expected + mid-flight; the entry is already omitted from bundles, so validation + reports it without failing; +- **current/approved entries**: a placeholder mismatch is a hard validation + failure; and +- **automation and import pipelines**: a produced target with mismatched + placeholders is demoted to fuzzy rather than committed as current. + +Source comparison is a semantic comparison of parsed source strings after +documented text normalization. Line folding, wrapping, and PO escaping are +serialization concerns and must never affect comparison. Reconciliation must +never update an entry's stored source without either confirming or replacing +the target, or marking the entry fuzzy. + +If translator notes or placeholder semantics can change the required +translation without changing visible English, the source-signature contract +must include that information or explicitly invalidate the entry. + +Retired entries (`#~`) are kept only while they provide useful translation +memory for automation; a deterministic cleanup policy removes them rather than +letting them accumulate indefinitely. + +## Message ID and placeholder policy + +The current catalog undermines the stable-ID premise in two ways the format +alone cannot fix: 8,981 of 11,564 keys (77.7%) are codemod-generated content +hashes, and 825 of 954 interpolated strings use positional placeholders +(`{{value0}}`) that carry no meaning for a translator or a machine-translation +prompt. + +Policy: + +- hashed IDs already in the desktop catalog as of this decision (2026-07-30) + are grandfathered as opaque stable IDs; the generating codemod must not be + rerun against existing keys, and no mass rename happens during this + migration; +- newly minted hash IDs — including in-flight bridge catalogs not yet merged + or merged after this decision — are **not** grandfathered: they are renamed + to intent-named IDs in a dedicated change adjacent to their landing, before + PO becomes canonical for that surface, never buried inside an otherwise + reviewed feature PR; +- new keys must use intent-named IDs and named interpolation placeholders; +- converting positional placeholders to named ones requires per-message + semantic judgment (the name is part of the translatable contract), not a + mechanical rename; and +- legacy IDs and positional placeholders are improved opportunistically when + the copy itself is touched, never in bulk. + +## Runtime and source ownership + +The ownership chain is: + +```text +product code and explicit dynamic declarations + | + v + extracted current English source + | + v + sparse canonical target-locale PO files + | + v + deterministic i18next JSON bundles + | + v + lazy-loaded offline app resources +``` + +Inline English defaults remain readable at call sites and provide extraction +input. Static extraction and explicit declarations for genuinely dynamic keys +must reconcile to one current English translation source. CI must reject +missing declarations and incompatible defaults rather than creating a +permanent exception database. + +Renderer, Electron main, web, SSH, WSL, and packaged execution continue to +consume the same logical runtime bundles. The compiler and build paths must use +cross-platform path handling and deterministic line endings. + +Two additional surfaces are in scope: + +- **Mobile.** The mobile app is acquiring its own catalog tree with its own + key scheme. Mobile must adopt the same canonical contract, ID policy, and + compiler — with its own PO files — rather than a second bespoke pipeline. + Mobile keys must not be folded into the desktop catalogs, and in-flight + mobile catalog JSON is a bridge the migration replaces, not a canonical + source. Mobile requires **two deterministic projections** from the same PO + source: the mobile i18next JSON bundle, and the native metadata resources + (iOS `InfoPlist.strings`, Android resources) that render before the JS + runtime exists. i18next fallback cannot cover pre-JS surfaces, so for a + missing, stale, or pending-approval native entry the compiler must either + omit the locale-specific native key with proven OS/base-locale fallback on + both platforms, or emit current English under a documented platform rule. + The intentional locale-ID mapping (JS `zh` vs native `zh-Hans`) is part of + the projection contract. The migration covers both projections. +- **Plugin language packs.** Language packs remain external overrides + validated against compiled core keys. They are consumers of the contract, + not another canonical source, and the compiler must leave their runtime + path intact. + +## Translation automation + +The architecture is incomplete until translation work is delta-driven. +After the compiler and migration are stable, automation should: + +1. reconcile entries affected by merged English changes (update `msgid`, + preserve `#| msgid`, set fuzzy) and find target entries that are missing + or stale; +2. batch only those entries into a translation change; +3. supply translator notes, glossary terms, placeholder rules, the previous + source from `#| msgid`, and relevant existing translations; +4. preserve all unaffected target entries byte-for-byte; +5. mark runtime eligibility and provenance honestly; +6. run placeholder, terminology, formatting, and catalog validation, demoting + invalid output to fuzzy; and +7. fall back to English rather than shipping an invalid target. + +Human review should be risk-based. Destructive actions, authentication, +billing, privacy, security, legal copy, OS permission prompts (camera, +microphone, photos, local network), native app metadata, and other sensitive +flows require review. Routine labels and descriptions may use validated machine translation +under the adopted release policy. A model-provided confidence score alone is +not sufficient release evidence. + +Catalog QA should include an identical-to-English guard implemented as a +ratchet with reviewed exemptions, not a blanket prohibition: brand names, +commands, and terms that legitimately remain English live in the exemption +inputs, and the untranslated ratio for everything else must not rise. + +Glossary and forbidden-translation rules belong in stable QA inputs. The +existing repair-script policy data (glossaries, never-translate lists, +per-locale overrides) is converted into those inputs. They must replace +historical whole-catalog repair scripts rather than coexist with them as +another source of product behavior. + +## Rollout + +### PR A: decouple feature copy — merged + +PR #8512: + +- permits sparse target catalogs; +- makes English runtime fallback authoritative for missing values; +- makes catalog synchronization update English only; +- preserves existing target values and rejects placeholder incompatibility; +- adds maintained extraction and CI verification; and +- removes whole-catalog translation and repair commands from ordinary product + workflows. + +PR A is independently useful and format-neutral. It stops new parity work, but +it does not permanently model reviewed or stale translation state. + +PR A also created a deletion ratchet: extra target-locale keys hard-fail +verification and sync no longer edits targets, so an English key cannot be +retired without hand-editing every target catalog. Orphaned English keys +(2,055 unreferenced at time of writing) grow with every rename until PR C +lands. PR C should not wait long. + +### PR B: define the source and compiler + +PR B must remain a small architecture and implementation proof. It should add: + +1. the constrained PO profile and its serialization normalization; +2. extraction into the current English source; +3. sparse source/target parsing via maintained PO tooling; +4. deterministic, read-only i18next bundle compilation, omitting entries + whose stored source mismatches current English or that are fuzzy — with a + compiler shape that admits additional per-locale projections (the mobile + native-resource output) even though PR B implements only the i18next + bundle; +5. a separate reconciliation command owning all PO mutations (`msgid` + update, `#| msgid` preservation, `#, fuzzy`); +6. state-dependent placeholder validation; +7. representative fixtures for interpolation, plural-suffixed keys, multiline + copy, translator notes, and source changes; and +8. packaged-build integration across local and remote execution boundaries. + +Acceptance tests must assert every workflow field — state, previous source, +notes, retirement — field-by-field through parse → modify → serialize cycles. +Byte-identical round-trip alone is not evidence: a lossy parser faithfully +reproduces its own losses, so a round-trip gate can pass while the fields that +justify the format are silently destroyed. This failure mode was demonstrated +against the dominant XLIFF library during the format review. + +It must not migrate the complete locale inventory. That keeps the format and +compiler independently reviewable and makes rejection inexpensive. + +### PR C: migrate existing translations once + +The migration must: + +- export all current stable English IDs and values; +- import real target values without retranslating them; +- preserve known reviewed corrections; +- mark unproven values as pending approval, with imported provenance — + bridge catalogs in particular mix reused desktop translations, machine + translation, and manual corrections, and must be classified rather than + assumed approved; +- remove copied-English parity filler unless it is intentionally English, + seeding the identical-to-English exemption inputs from the existing policy + data; +- turn terminology and known mistranslations into glossary and QA inputs; +- drain the orphaned-English-key ratchet and delete the retired bootstrap and + repair script files; and +- explain every difference between current and compiled runtime bundles. + +Every existing target value must be byte-preserved, explicitly retired, or +classified as filler. No Git-history inference should remain in the permanent +runtime or verification path. + +### PR D: switch ownership and delete the bridge + +After bundle equivalence is proven: + +- PO becomes the only editable target translation source; +- generated runtime JSON stops being a canonical input; +- development, test, build, and packaging compile the bundles + deterministically; +- a JSON→PO importer ships for contributors, so existing full-catalog + community PRs can be converted instead of abandoned; +- legacy bootstrap, repair, override, and migration-only bookkeeping is + removed; and +- ordinary CI runs one focused extraction and compile verification path. + +### Translation automation + +The first automation follow-up should create or update localization-only +changes containing only missing and stale entries. It should not rewrite a +whole locale, modify feature code, or block the originating feature change. + +## Alternatives considered + +### Constrained XLIFF 2.0 — original choice, reversed 2026-07-30 + +XLIFF 2.0 has the best abstract schema fit: stable IDs, source and target in +one unit, standardized workflow state, and categorized notes. The decision was +reversed when the stated uncertainties resolved against it: + +- the dominant JS XLIFF library silently discards `state`, `subState`, and + note categories — the fields that motivate the format — while reporting a + clean round-trip, so the planned acceptance gate would have passed + vacuously; the only spec-faithful JS alternative has ~90 weekly downloads, + a single maintainer, and EPL-1.0 licensing; +- XLIFF 2.0 core defines no previous-source mechanism, so the "what changed" + payload for translation automation requires a custom extension that breaks + the interoperability that justified the format (leaving the old `` + in the target file and comparing against a separate current-English file is + possible, but then translators and tools see the wrong current source + unless another projection is built — PO represents the joined working state + natively); +- tool and platform support for XLIFF 2.x remains weaker than 1.2 more than a + decade after standardization; no verified case of XLIFF 2.0 as an in-repo + canonical source was found, and the closest public precedent for this exact + compiler design chose 1.2; and +- XML is the format most likely to let a hand-edited community PR fail on a + malformed entity, and there is no cross-tool XML formatting convention, so + external editors produce whole-file diffs; Orca's translation contributions + arrive overwhelmingly as direct catalog PRs. + +If a translation provider requires XLIFF, Orca should add a deterministic +import/export adapter at the boundary rather than change the canonical +representation. + +### XLIFF 1.2 + +Broader legacy tool support than 2.0, but more tool-specific dialects and a +less coherent data model, and it shares XML's contributor and formatting +costs. Adapter-only, as above. + +### Direct JSON or TypeScript catalogs + +These are simple runtime inputs, but they do not standardize source snapshots, +translator context, or review state. Meeting Orca's requirements would require +custom sidecars or object schemas and synchronization rules. That recreates +much of a bilingual standard while retaining the parity and stale-state risks +the migration is intended to remove. + +### Bespoke bilingual JSON — the current fallback + +A JSON schema with embedded per-locale state, source snapshots, and notes is a +proven model (a major platform vendor ships exactly this shape, with per-key +extraction state including staleness and per-locale review state) and would +add no parsing dependency. It is second to PO because PO's workflow fields are +standard rather than bespoke, existing translation editors and open tooling +understand them, and its diffs are the smallest of the three formats. If the +PR B PO proof fails, adopt this — not XLIFF — before PR C. + +### Platform-native catalogs + +Platform-native string catalogs provide strong translation state on their +own platform but are not a suitable authority for Orca's macOS, Linux, +Windows, web, WSL, and SSH surfaces. + +### Proprietary translation platform + +A translation platform may later operate on the PO boundary, but it should +not become Orca's sole source of truth or a runtime dependency. Selecting one +before the repository contract exists would create premature vendor coupling. + +### Peer practice + +Inspectable applications validate the architecture more strongly than any one +format: + +- mature systems use stable keys or source messages, authoritative English, + sparse targets, and runtime fallback; +- applications that keep canonical translations in-repo with PR-based + contribution use PO or stateful JSON catalogs; none inspected uses XLIFF + 2.0 as a canonical source, and the only XLIFF observed was 1.2 as + interchange into an external pipeline; +- the delta-driven machine-translation model this document targets is already + shipping in peer practice, keyed by per-entry source tracking; +- structural key parity is not a completeness signal — peer catalogs exist + with perfect parity and majority copied-English content, which is what the + identical-to-English ratchet detects; and +- gates that are written but not enforced decay — every verification in this + plan must run in CI from the PR that introduces it. + +Closed-source applications do not publish enough of their authoring pipelines +to establish a format decision. Orca therefore chooses based on its own +requirements rather than presumed competitor internals. + +## Confidence and decision gate + +Confidence is: + +- **97%** in the overall sparse-source, source-snapshot, deterministic-compiler, + and English-fallback architecture; +- **90%** in PO over constrained XLIFF 2.0; +- **85%** in PO over bespoke bilingual JSON; and +- **95%** that a migration-free PR B prototype on PO is the correct next step. + +The remaining PO uncertainty concerns exact serialization normalization +(folding, escaping) across the tools contributors use, the provenance +convention recorded alongside `#, fuzzy`, and the `#~` retention policy. + +PR B closes the decision gate only if its representative fixtures preserve +every workflow field through parse → modify → serialize verified +field-by-field, output is deterministic, diffs remain reviewable, and the +compiler/build integration is maintainable. If that proof fails, adopt bespoke +bilingual JSON before PR C. Do not fall back to XLIFF 2.0, add compatibility +layers, or create custom sidecar state merely to preserve a format choice. + +This is a deliberate, reversible senior-engineering decision — and it has +already been exercised once: the original XLIFF 2.0 selection was reversed +when evidence resolved its stated uncertainties, at zero migration cost +because the staged rollout deferred format commitment until PR B. + +## Explicit non-goals + +The completed system must not: + +- require every target locale to contain every English key; +- copy English into target catalogs to simulate coverage; +- infer permanent translation state from Git history; +- retranslate or rewrite complete catalogs for ordinary copy changes; +- make generated runtime JSON another hand-edited source; +- rename existing hashed message IDs in bulk; +- treat plugin language packs as a canonical source; +- block feature PRs while translations catch up; +- require runtime network access; or +- maintain multiple canonical translation databases. diff --git a/i18next.config.ts b/config/i18next.config.ts similarity index 100% rename from i18next.config.ts rename to config/i18next.config.ts diff --git a/config/knip.json b/config/knip.json new file mode 100644 index 00000000000..c5b96b5a87d --- /dev/null +++ b/config/knip.json @@ -0,0 +1,46 @@ +{ + "$schema": "https://unpkg.com/knip@5/schema.json", + "entry": [ + "src/main/index.ts", + "src/preload/index.ts", + "src/preload/browser-window-close.ts", + "src/main/daemon/daemon-entry.ts", + "src/main/plugins/plugin-host-entry.ts", + "src/main/computer/sidecar-entry.ts", + "src/main/speech/stt-worker.ts", + "src/main/warp-themes/warp-theme-parser-worker.ts", + "src/main/ai-vault/session-scanner-opencode-sqlite-worker-entry.ts", + "src/main/ports/port-scan-command-worker-entry.ts", + "src/main/ipc/parcel-watcher-process-entry.ts", + "src/main/hang-watchdog/main-thread-hang-watchdog-entry.ts", + "src/main/codex/codex-app-server-grant-entry.ts", + "src/main/agent-hooks/managed-agent-hook-controls.ts", + "src/main/claude-accounts/keychain.ts", + "src/renderer/src/main.tsx", + "src/renderer/src/popout.tsx", + "src/renderer/src/web/main.tsx", + "src/renderer/src/**/*.worker.ts", + "src/cli/index.ts", + "src/relay/relay.ts", + "src/relay/wsl-agent-hook-relay.ts", + "config/scripts/**/*.{mjs,cjs,js,ts}", + "config/build-plugins/**/*.ts", + "electron.vite.config.ts", + "vite.web.config.ts", + "config/vitest.config.ts", + "config/i18next.config.ts", + "config/electron-builder.config.cjs", + "config/oxlint-plugins/**/*.{js,mjs,ts}", + "tests/**/*.{ts,tsx,mjs}", + "**/*.test.{ts,tsx}" + ], + "project": [ + "src/**/*.{ts,tsx}", + "config/scripts/**/*.{mjs,cjs,js,ts}", + "config/build-plugins/**/*.ts" + ], + "ignore": ["mobile/**", "out/**", "dist/**", "node_modules/**", "resources/**"], + "ignoreDependencies": ["electron", "@types/*"], + "ignoreExportsUsedInFile": true, + "includeEntryExports": false +} diff --git a/config/localization-audit.md b/config/localization-audit.md index 2090dcbb7b4..437ecc6facf 100644 --- a/config/localization-audit.md +++ b/config/localization-audit.md @@ -4,6 +4,9 @@ This is the pre-work artifact for migrating Orca to a localized UI.

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

ANSI/DEC compatible parser described by\n * Paul Williams (https://vt100.net/emu/dec_ansi_parser).\n *\n * To implement custom ANSI compliant escape sequences it is not needed to\n * alter this parser, instead consider registering a custom handler.\n * For non ANSI compliant sequences change the transition table with\n * the optional `transitions` constructor argument and\n * reimplement the `parse` method.\n *\n * This parser is currently hardcoded to operate in ZDM (Zero Default Mode)\n * as suggested by the original parser, thus empty parameters are set to 0.\n * This is not in line with the latest ECMA-48 specification\n * (ZDM was part of the early specs and got completely removed later on).\n *\n * Other than the original parser from vt100.net this parser supports\n * sub parameters in digital parameters separated by colons. Empty sub parameters\n * are set to -1 (no ZDM for sub parameters).\n *\n * About prefix and intermediate bytes:\n * This parser follows the assumptions of the vt100.net parser with these restrictions:\n * - only one prefix byte is allowed as first parameter byte, byte range 0x3c .. 0x3f\n * - max. two intermediates are respected, byte range 0x20 .. 0x2f\n * Note that this is not in line with ECMA-48 which does not limit either of those.\n * Furthermore ECMA-48 allows the prefix byte range at any param byte position. Currently\n * there are no known sequences that follow the broader definition of the specification.\n *\n * TODO: implement error recovery hook via error handler return values\n */\nexport class EscapeSequenceParser extends Disposable implements IEscapeSequenceParser {\n public initialState: number;\n public currentState: number;\n public precedingJoinState: number;

They assert one atomic store publication clears only exact-target PTY indexes, null-PTY activation remains unchanged, relay identity survives, Git and folder panes retry symmetrically, another target/local/WSL/runtime panes remain byte-identical through target snapshot hydration and reconnect, only an accepted exact failure or timeout starts the second attempt, two 31-second timeouts cannot start a third settlement-triggered attempt, rejected stale/mismatched acknowledgements preserve every store map, and concurrent split-pane spawn and reattach callbacks both commit under the same attempt ID after the first success replaces pending state with live shared authority. A sibling failure revokes that shared authority and starts exactly one second attempt; duplicate failures and late first-attempt PTY callbacks preserve the second attempt and every state map. Attempt-two failure retains continuation authority for later siblings, primary exit promotes a bound survivor or preserves the lease until a late sibling binds, and primary plus non-primary detach retain exact authority and history on both resulting tabs. Both remount callbacks consume split-count activity suppression, intentional dispose emits no failure/timeout, and a same-attempt StrictMode remount still owns one timeout. Hydration clears an untrusted PTY hint without clearing its current pending owner, healthy current-authority bindings suppress correction, hydration finalizes once, and reconnect emits no paired close lifecycle. A provider-level session-ID reattach returns an incarnation, then a legacy exit without an incarnation must resolve to that returned identity rather than minting a fallback identity.

Diagnosis split it into a regression and a pre-existing class gap: - -- The **regression** was a title-normalization change (PR `7447`) that stopped idle OMP - titles from producing the sidebar's title-derived fallback row. Decision: the sidebar is - moving to **hook-driven rows only** (fallback removal in flight, separate PR), so the - fallback was not restored. -- The **class gap** is that agent hooks have never worked from inside WSL for any agent. - Two scoped PRs fixed it for OMP alone (merged, live-validated on a Windows+WSL2-NAT rig): - - PR `7642` — Orca-managed WSL shells wrap interactive `omp` invocations with - `--extension "$ORCA_OMP_STATUS_EXTENSION"` (the env var is WSLENV `/p`-translated so - the WSL process reads the extension out of the Windows filesystem via `/mnt/c`). - - PR `7641` — when the extension's loopback POST cannot connect, it delivers via - Windows-side `/mnt/c/Windows/System32/curl.exe` (a Windows process, so *its* - `127.0.0.1` is the loopback Orca actually binds). Fire-and-forget spawn, - `--noproxy 127.0.0.1`, memoized WSL/curl probes, load-tolerant timeouts - (`--connect-timeout 3 --max-time 10`; 0.5s dropped events under load). - -This document is the full context for the general fix: every other hook client is still -dead from WSL, and the hooks-only sidebar change makes this work the gate for the -Windows+WSL story. - -## Why hooks don't work on Windows+WSL — two independent gaps - -### Gap A — transport - -The hook listener binds `127.0.0.1` only, deliberately (`src/main/agent-hooks/server.ts`, -`listen(0, '127.0.0.1')`; auth via `X-Orca-Agent-Hook-Token`, 403 otherwise). Every hook -client POSTs to a hardcoded `http://127.0.0.1:$ORCA_AGENT_HOOK_PORT/hook/`. - -WSL2 under default **NAT** networking is a VM with its own network namespace. Microsoft's -localhost forwarding is **one-way (Windows→WSL only)**: `127.0.0.1` inside WSL is WSL's -own loopback, so every POST dies `ECONNREFUSED` — silently, because hook clients are -deliberately fail-open. Reaching Windows from WSL would require the host vNIC IP (changes -per boot) + a non-loopback listener bind + a firewall rule — all three conflict with the -loopback-only security posture. - -The env coordinates DO cross correctly (`src/main/pty/wsl-orca-env.ts` -`addOrcaWslInteropEnv`: WSLENV `PORT/u TOKEN/u ENV/u VERSION/u` plus -`ORCA_AGENT_HOOK_ENDPOINT/p` path-translated; called from `src/main/ipc/pty.ts` and -`src/main/daemon/pty-subprocess.ts`). The address is simply unreachable. - -Opt-in **mirrored** networking (Win11, `.wslconfig`) shares loopback and makes plain fetch -work — the fix must not fight it. No `wslinfo` probing is needed: under mirrored mode the -relay's preferred-port bind collides with the Windows listener and the `EADDRINUSE` -fallback (below) handles it, while clients that go straight to the shared loopback reach -the Windows listener directly. Both delivery paths stay valid. - -### Gap B — installation - -Hook configs and scripts are written to the **Windows** home by every hook service: -Claude `settings.json` + managed scripts, Codex config, Gemini/Cursor/Droid/Devin/Grok/ -Copilot scripts, Amp/OpenCode plugin files, the Pi/OMP extension file. An agent inside WSL -reads the **WSL-side** `$HOME` and sees none of it. There is zero WSL-targeted install -code in `src/main/agent-hooks/` or any hook service. SSH remotes have the exact precedent -needed: dedicated remote installers (`src/main/ssh/ssh-relay-session.ts` remote -settings.json handling; PR `7744` installed Droid/Copilot hooks over SSH). - -Consequence: even mirrored-networking users get no hooks — transport fine, configs absent. -OMP escapes Gap B by *pointing across* the boundary (`/mnt/c` path via `/p` translation) -rather than installing WSL-side; that trick can carry file *content* for some clients, but -shell hooks still execute inside WSL and then hit Gap A regardless. - -## Transport map — every client, how it posts - -Endpoint file contract: `writeEndpointFile` (`src/shared/agent-hook-listener.ts`) emits -exactly four keys (`ORCA_AGENT_HOOK_PORT/TOKEN/ENV/VERSION`) to `endpoint.env` (POSIX) / -`endpoint.cmd` (Windows) — **no host field**. Shell clients source it to refresh stale -coords after an Orca restart; node clients parse it. It is never executed as a delivery -script. Clients prefer endpoint-FILE coords over env (restart re-coordination) — any -transport change must preserve that property. - -| Client | Mechanism | Runtime that POSTs | -| --- | --- | --- | -| Claude, Codex, Gemini, Cursor, Droid, Devin, Grok | managed shell script | `curl` (POSIX) / `curl.exe` (Windows), built in `src/main/agent-hooks/installer-utils.ts` | -| Copilot | managed script | `curl` (POSIX) / PowerShell `Invoke-WebRequest` (Windows) | -| command-code | managed script (parse-not-source hardened) | `curl` | -| Amp, OpenCode | in-process node plugin | `fetch` | -| Pi / OMP | bundled in-process extension (`src/main/pi/agent-status-extension-source.ts`) | `fetch`, now with the WSL curl.exe fallback | - -All of them target `127.0.0.1`. - -## Status quo + why this gates the hooks-only sidebar - -Today the worktree-card rows still have a title-derived fallback producer -(`src/renderer/src/components/sidebar/worktree-title-derived-agent-rows.ts`), so WSL users -DO currently see rows for title-rich agents (Claude `✳`/spinner titles, Gemini glyphs) — -degraded (generic text, no prompt/last-message preview, no notifications) but present. -Title-poor agents are dark (Codex — hence GH `6907`). When the hooks-only change removes -that producer, **every non-OMP agent in a WSL worktree loses its card row entirely until -this work ships**. Hook fidelity adds: prompt + last-assistant-message previews, -waiting/blocked precision, completion notifications, AI Vault / native chat session -integration. - -## Solution design — WSL relay + WSL-side installation - -### Transport (Gap A): guest-resident relay, host-owned stdio - -Run a small receiver **inside WSL on WSL's own loopback, listening on the very port the -clients were already given** (`$ORCA_AGENT_HOOK_PORT` — free inside WSL, since that port -only exists on the Windows side). Unmodified clients then deliver successfully with -**zero client changes**; the reporter's diagnostic relay in GH `7565` proved this shape -live. Forward each parsed envelope to the Windows host over the relay's **own stdio** -(Orca spawns it via `wsl.exe`, so it owns that pipe). Ingest through the existing trust -boundary: `agentHookServer.ingestRemote` (`src/main/agent-hooks/server.ts`), envelope -shape `src/shared/agent-hook-relay.ts` — identical to the SSH relay, which runs a -loopback-only receiver on the remote box and forwards over the SSH control channel. - -**Port binding.** Bind the inherited `$ORCA_AGENT_HOOK_PORT` first — it keeps every -already-crossed coordinate (env and the `/p`-translated endpoint file) truthful with zero -divergence. On `EADDRINUSE` inside the guest, fall back to the SSH relay's own pattern: -bind `127.0.0.1:0`, write a **WSL-side endpoint file**, and point WSL PTYs' -`ORCA_AGENT_HOOK_ENDPOINT` at it (clients already prefer endpoint-file coords over env). -The relay writes that WSL-side endpoint file in **both** modes so restart re-coordination -never depends on `/mnt/c` translation being readable. - -Lifecycle: one relay per distro **per Orca instance** (concurrent instances have distinct -ports, so guest listeners never collide); **ensure** — not just start — whenever a WSL PTY -exists: first spawn *and* daemon-PTY reattach after an Orca restart (WSL PTYs survive in -the daemon; the new instance has a new port + token and must respawn the relay before -surviving agents re-coordinate). The relay **exits when its stdin closes**: a lingering -guest listener would let WSL's own Windows→WSL forwarder grab the freed Windows-side port -and blackhole stale Windows-side hook posts. Restart if WSL restarts; token still -validated at the relay's HTTP receiver; harmless under mirrored networking (bind -fallback) and inert on non-WSL platforms (ensure only fires from WSL PTY spawns). - -Reliability contract (invariant class `agent-session.hook-transport`): hook clients are -fail-open silent, so the relay must not be — spawn failures, `EADDRINUSE` fallback, and -forward errors each leave a diagnosable breadcrumb; the `wsl.exe` "Catastrophic failure -(E_UNEXPECTED)" retry is **bounded** with backoff, never a spawn loop. Oracle: provider- -contract tests with fault injection (stdin close → exit, occupied port → fallback + file -rewrite, envelope round-trip to `ingestRemote`) rather than end-to-end flows only. - -Design notes from a survey of comparable WSL-capable tools (kept nameless per policy): -- Guest-resident component + host-owned channel + guest-side installation, explicitly - reusing the tool's SSH-remote machinery, **is the established pattern**. No surveyed - tool makes guest processes dial back to a Windows-localhost listener — the merged OMP - curl.exe stopgap is the outlier as a primary path (but see the round-4 revised - stance below: it survives as the no-node fallback). -- Prefer host-owned **stdio** over Windows→WSL localhost port forwarding (wslhost - forwarding is known-flaky under load; one surveyed tool dials the distro vNIC IP just to - avoid it — stdio sidesteps the question entirely). -- WSL offers no persistent control channel between separate `wsl.exe` invocations — - collapse the relay's ensure-installed + launch into **one idempotent script per spawn**. -- Install into the guest from inside the guest (download/extract in WSL) or stream the - binary through `wsl.exe` stdin — not by copying through `/mnt/c`. - -### Installation (Gap B): WSL-side hook installers - -Write agent hook configs/scripts into the WSL-side home, per agent, analogous to the SSH -remote installers — via `wsl.exe`-executed scripts (preferred, mirrors SSH most closely) -or `\\wsl.localhost\\...` writes. Without this half, the relay receives nothing: -the hook clients themselves are absent from the WSL filesystem. - -## Alternatives considered (and why not) - -1. **Endpoint-file host/URL field** — the file already crosses into WSL (`/p`-translated), - but clients read only PORT/TOKEN and hardcode the host, so all ~13 still need edits; - and a WSL-reachable listener bind breaks the loopback-only posture (LAN exposure, - firewall prompts). -2. **Replicate the curl.exe bridge per client** — the shell clients share ~2 generated - builders so it is cheaper than it sounds, but it is N point fixes, requires WSL interop - enabled (`/etc/wsl.conf` can disable it), pays a per-event process spawn (load-sensitive, - see validation facts), and keeps the ecosystem-outlier direction. -3. **Listener-side bind changes / rely on mirrored networking** — posture conflict / - opt-in only. -4. **OSC 9999 in-band status** (`src/shared/agent-status-osc.ts`, parsed per-pane in - `pty-transport.ts` and `orca-runtime.ts`) — zero-network and pane-attributed, but only - viable for in-process clients and carries status payloads, not the full hook event - vocabulary (prompts, tools, completion) — cannot replace the pipeline. - -## Facts + gotchas from the 2026-07-08 Windows-rig validation - -- curl.exe interop delivery works under NAT (shipped for OMP), but per-event process spawn - is load-sensitive: `--connect-timeout 0.5` dropped 3/3 events to a *healthy* listener - under load; fine at 3s. A resident relay avoids per-event spawns entirely. -- `wslinfo --networking-mode` distinguishes NAT vs mirrored. -- Clients prefer endpoint-FILE coords over env. Testing gotcha: unset - `ORCA_AGENT_HOOK_ENDPOINT` in synthetic tests or events go to the real running app. -- Server ingest silently drops paneKeys that are not `uuid:uuid`-shaped — use real-shaped - keys in synthetic validation. -- OMP is a Bun single-file binary; Bun's `node:child_process`/`fetch` compat held. Other - in-process clients run inside their agents' runtimes — verify per runtime. -- Environmental: fresh WSL 2.7.10 intermittently threw "Catastrophic failure - (E_UNEXPECTED)" from `wsl.exe -d -- bash -lc` under concurrent spawn load - (cleared by `wsl --terminate`). The relay spawn path should tolerate/retry this. -- Fork-PR CI runs sit in `action_required` until approved: - `gh api repos/stablyai/orca/actions/runs//approve -X POST`. - -## Acceptance - -On a default-config Windows 11 + WSL2 **NAT** machine: launch **Codex or Claude** -(explicitly not OMP) in a WSL worktree → live hook-driven worktree-card row with status -transitions and a completion notification; hook listener still bound to Windows loopback -only; zero per-client transport changes; hooks installed WSL-side automatically (no manual -config); harmless under mirrored networking and inert on non-WSL platforms. After an Orca -restart with the WSL agent still running (daemon-surviving PTY), status events resume -without relaunching the agent. - -## 2026-07-09 Windows-rig validation follow-ups - -The first live GUI run proved every mechanism in isolation but failed end-to-end, yielding -two fixes: - -1. **Link death must be handled, not just child death.** A mux protocol error or timeout - can kill the host↔guest link while the guest process (and its 204-returning receiver) - stays alive — the exact observed signature: hooks POST 204, store never populates. - `wsl-hook-relay-link.ts` now guarantees exactly-once death handling from either signal; - the manager breadcrumbs it, kills the child, and self-restarts after a short cooldown - (a live agent session produces no new PTY spawns to re-trigger ensure). - `ORCA_WSL_HOOK_RELAY_DEBUG=1` traces every received envelope pre-ingest so a live rig - can pinpoint any residual drop. The full host chain is pinned by a live integration - test (real bundle over real child stdio through the real manager into a real - `ingestRemote`). -2. **(Round 2) The renderer's SSH-era ownership gate dropped `wsl:*` events.** With the - link fixed, envelopes reached `ingestRemote` and the durable cache, but - `useIpcEvents.applyAgentStatus` compares the stamped connectionId against the owning - repo's — `"wsl:" !== null` for a local repo, so every WSL-relayed status died - before `setAgentStatus`/notifications. Fix: `wsl:*` ids are transport provenance, not - ownership — the gate normalizes them to local (null) via - `isWslHookRelayConnectionId`, while still rejecting WSL-stamped events against - SSH-owned repos. Provenance stays stamped (it made the drop diagnosable in the first - place). -3. **Codex reads a redirected home.** Orca launches WSL Codex with `CODEX_HOME` pointed at - the managed runtime home (`~/.local/share/orca/codex-runtime-home/home`), so installing - hooks to `~/.codex` left Codex dark. The installers now accept an explicit codex home; - the trust write into `config.toml` is deferred while that file doesn't exist (the - launch path seeds it only-if-absent — creating it first would cancel the seed), and the - manager re-runs the idempotent installers on later ensures (throttled) to upsert trust - once the seed lands. Consequence: the very first WSL Codex session after a cold relay - may miss hooks; the next one has them. - -## 2026-07-09 adversarial-review hardening (pre-rig round 3) - -Four independent review lenses over the full diff; confirmed findings fixed: - -- **Endpoint identity (all 4 reviewers)**: the guest endpoint dir was keyed by the - ephemeral Windows hook port, so a daemon-surviving agent kept sourcing the DEAD - `port-P1` file after an Orca restart — breaking the restart-resume acceptance criterion - and regressing shipped OMP recovery. Now keyed by a restart-stable instance key - (hash of the Windows endpoint file path = userData + namespace, crossed via - `ORCA_WSL_HOOK_INSTANCE`): the restarted instance's relay REWRITES the same file, which - is exactly what re-coordinates survivors. -- **Restart policy**: every failure now arms the restart timer (one failed relaunch no - longer ends self-recovery), and the timer probes `wsl --list --running` first — `wsl -d` - BOOTS a stopped distro, so recovery must never resurrect a VM the user shut down; a - stopped distro's state is dropped instead (next WSL terminal re-ensures). Failure - counters only reset after 2 min of stable uptime, so connect-then-die loops escalate to - the 10-min cap instead of cycling every 10s. -- **Install-dir versioning**: the guest install dir is namespaced by bundle version, so - concurrent Orca instances with different bundles (dev + prod) never reinstall over each - other; tmp files carry the guest PID. The install spawn also gained the 30s timeout it - was missing (a wedged wsl.exe could previously pin the state machine at 'starting' - forever). -- **Guest node resolution**: candidates (PATH, nvm glob, fixed paths) are each - version-probed, first pass wins — an apt node 12 on PATH no longer masks an nvm node 20 - into a false "no node >= 18" 10-minute cooldown. -- **wsl.exe text handling**: `WSL_UTF8=1` on all spawns + NUL-stripping on stderr, so the - "Catastrophic failure" transient-retry matcher and breadcrumbs survive UTF-16LE output. -- Smaller: ordered post-sentinel chunk handoff (frame-decoder desync race), port-fallback - breadcrumb now reaches host logs via the home handshake, bad home reply fails the - connect (was: silently 'running' without installs), missing-bundle warn-once, distro - map keys case-normalized, `disposeAll` wired to app `will-quit`, single-spawn Codex - trust catch-up via a one-shot 60s reinstall timer. - -Accepted gaps (reviewed, deliberately not addressed here): old version-namespaced -install dirs accrete across upgrades (~200KB each); an outdated running daemon -/p-translates the guest endpoint path until it restarts (hook scripts fall back to env -coords, which same-port binding keeps correct); default-distro resolution caches the -first non-empty answer for the app run. - -`wslDistroCache` no longer caches a transient empty list for the app run — an empty -result is re-probed after a short window, so a distro registered mid-session is picked -up. `isWslAvailable` likewise re-probes instead of latching a failure. - -## 2026-07-09 round-4 external adversarial review - -A second adversarial sweep (five independent lenses: guest relay + fs bridge, host -lifecycle state machine, app integration + renderer gate, design-vs-alternatives, and a -platform fact-check of every WSL claim). Design verdict: the guest-resident relay over -host-owned stdio is the right architecture — the zero-per-client-change chokepoint is -what the curl.exe alternative cannot match, and the lifecycle weight is inherent to any -guest-resident helper. Confirmed findings, all fixed on this branch: - -- **`dropState` identity race (major)**: the recovery timer re-checked state identity - only BEFORE the async `wsl --list --running` probe; an ensure() landing during the - probe could get its fresh state deleted by key — orphaning a live relay child outside - the map (unkillable by `disposeAll`, duplicate relay on next ensure). Fixed: identity - re-check after the probe await + identity-guarded delete in the manager. -- **Distro-running probe failed OPEN**: any probe error (including its 10s timeout) - reported "running", so recovery could `wsl -d` — and thereby BOOT — a distro the user - shut down, in exactly the wedged-wsl.exe failure mode where the probe errors. Now - fails closed: drop the state; the next WSL PTY spawn re-ensures. -- **Spawn form hardened to `--exec`**: `wsl.exe -- ` routes through the distro's - default login shell (Microsoft docs: only `--exec` runs "without using the default - Linux shell"), so a fish/nushell chsh could mangle the launch; `--exec sh -c`/-`s` - bypasses it and passes argv verbatim (no `$`-preprocessing, escaping shim dropped) — - same form as the Codex WSL login spawn. -- **Post-sentinel handoff microtask**: pending chunks flushed synchronously inside the - mux constructor, before the manager could register notification handlers — an - envelope arriving in the trailing bytes dispatched to zero handlers (recovered only - by the later replay request). Flush now rides a microtask: after the caller's - synchronous wiring, still ahead of any subsequent stdout IO event. -- **Relay process posture**: the guest relay now mirrors the SSH relay's - `uncaughtException` (log + exit → manager respawns) / `unhandledRejection` (log + - survive) handlers. -- **Replay cache recency cap**: the WSL relay has no per-pane teardown signal, so the - per-pane replay cache grew for the relay's lifetime; now capped at 256 panes, - evicting longest-idle first (meta map kept in lockstep). Backstop for SSH too. -- Smaller: guest launch script derives the stale-exit code from the shared contract - constant (was a hardcoded 42 twin); one-shot reinstall timer refuses to arm after - dispose; fs-bridge scope comment states the lexical (symlink-following) bound - honestly. New oracles: sentinel unit suite (chunk splits, overflow kill, timeout, - microtask handoff), fs-bridge scoping suite, 403 + fallback endpoint-file rewrite, - cache-cap eviction, and the recovery/manager race regressions. - -**Revised stance on the OMP curl.exe bridge — keep it, do not retire.** The relay -requires node ≥ 18 in the distro; a fresh WSL Ubuntu ships none, Codex CLI is a native -binary that brings none, and Claude Code's native installer no longer implies a system -node. A distro running only Codex would hit the no-node cooldown and stay dark — the -exact GH `6907` shape. The interop bridge is the one delivery path with no guest -runtime requirement, so it stays as the documented no-node fallback (currently wired -for OMP; extending it to the shared shell-script builders is the tracked follow-up if -no-node distros show up in telemetry). The relay remains the primary path: resident -(no per-event spawn cost) and interop-independent. - -## Implementation map - -- Guest: `src/relay/wsl-agent-hook-relay.ts` (entry; exits on stdin close), - `src/relay/wsl-hook-fs-bridge.ts` (home-scoped fs RPCs for installs), - `src/relay/agent-hook-server.ts` (`token`/`preferredPort` options + `EADDRINUSE` - fallback).

The in-memory reservation prevents Orca-internal concurrent collisions; an external process can still create the same path after the check, so this remains best-effort at the filesystem boundary. - -2. **Set the destination during `will-download`** - - In `BrowserManager.handleGuestWillDownload`, compute and reserve the path, then call `DownloadItem.setSavePath()` immediately while still in the `will-download` call stack. Do not pause for renderer approval, do not open `dialog.showSaveDialog`, and do not use `setSaveDialogOptions()` for this flow because that still preserves dialog behavior. If destination resolution or `setSavePath()` fails, release the reservation, cancel the item, and send or queue a failed terminal event with a specific, non-secret error. - -3. **Track downloads from start to finish in main** - - Replace the approval-centric state with browser download state: - - - `downloading`: save path is already assigned; item is progressing, waiting on network, or temporarily interrupted. - - `completed` / `failed` / `canceled`: terminal states sent to the renderer. - - Register `updated` and `done` listeners immediately in `will-download`, store latest received-byte count plus any terminal result, and keep the existing guest-to-tab queue so downloads that start before registration still surface when the tab binds. Queue state snapshots, not every progress event: if a download finishes before the tab registers, flush a started row followed by its terminal state so the renderer does not drop an orphan progress/finish event. If an unregistered guest is destroyed or retired before the tab binds, cancel its queued active downloads and release their reservations instead of only dropping the pending queue entry. Send exactly one terminal event per download, detach only this feature's listener references during cleanup, and release the reserved path on every terminal path and on explicit cancel. - -4. **Update IPC shape for browser-like status** - - Keep the existing renderer event channels if that keeps the diff smaller, but change the payload contract from "approval requested" to "download started" semantics. Include `browserPageId` on start/progress/finish when the tab is known, include `savePath` on start and terminal data, and keep progress payloads to `downloadId`, byte counts, and transient state. Remove the renderer `acceptDownload` path for normal browser downloads and delete the save-dialog IPC test; `cancelDownload` remains useful while an item is active. - -5. **Render browser chrome, not an approval prompt** - - In `BrowserPane`, replace the `Save` / `Cancel` prompt with a compact download row/list under the toolbar: - - - active row: filename, origin, progress label, `Cancel`; - - completed row: filename, "Downloaded" status, `Open`, `Show`, dismiss; - - failed/canceled row: filename, concise failure/cancel reason, dismiss. - - Track more than one download per pane so a second download does not hide the first. Cap visible recent completed rows to a small number, such as three, to avoid growing the browser surface. This is a per-pane transient list, not persisted history. - -6. **Use existing shell bridges for actions** - - Use `window.api.shell.openFilePath(savePath)` for `Open` and `window.api.shell.openInFileManager(savePath)` for `Show`. `openPath` is a legacy reveal wrapper whose `void` return type prevents the preload bridge from reporting success or failure back to the renderer. If either action fails or the file has been moved/deleted, show an inline or toast failure that does not claim the file opened. - -## Data Flow - -```text -Browser session will-download - -> BrowserManager computes and reserves ~/Downloads/name.ext - -> DownloadItem.setSavePath(path) during will-download - -> BrowserManager tracks item and sends/queues browser download-started - -> BrowserPane renders progress row - -> DownloadItem updated/done - -> BrowserManager sends progress/finished - -> BrowserPane shows completed row with Open / Show -``` - -## Edge Cases - -- Duplicate filenames must not overwrite existing files. -- Simultaneous same-name downloads in the same Orca process must not choose the same path before either file exists. -- Same-name reservation checks must respect platform path identity, including case-insensitive collisions on Windows. -- External filesystem races between path selection and Chromium's file creation are unavoidable with `setSavePath()`; treat them as residual risk, not a guarantee. -- Path traversal or separator-like filenames must collapse to a safe basename. -- Empty filenames fall back to `download`. -- Unknown total bytes should show received bytes or a generic "Downloading" state without broken math. -- Multiple simultaneous downloads from the same tab must render independently. -- A download that starts, progresses, or finishes before the webview registers must still appear once the tab binds. -- A queued download whose guest is destroyed or retired before registration must be canceled and release its reserved path. -- Since this design intentionally avoids a global persistent download manager, closing the owning browser tab must cancel active downloads rather than leaving hidden file writes with no chrome. -- `setSavePath()` failure should not leave a hidden, still-running download. -- `updated` events with `interrupted` state should keep the row honest without treating them as terminal; `done` is the terminal source of truth. -- Explicit cancel and Electron's eventual `done` callback must not produce duplicate terminal UI events. -- Completed file actions may fail if the file was moved/deleted after download; UI must report that honestly. -- On Windows, Linux, and macOS, all paths are built with Node/Electron path APIs. -- In SSH/remote workflows, the file is saved on the machine running the browser runtime; UI copy must not imply cross-machine transfer. -- Web clients keep their existing "handled by server browser" behavior unless the server-side browser implements equivalent events. - -## Test Plan - -- Unit: destination builder sanitizes names, preserves extensions, picks collision-free paths, respects active path reservations including platform path identity, releases reservations, and stops at a bounded suffix limit. -- Unit: `BrowserManager.handleGuestWillDownload` calls `setSavePath()` during handling, does not pause/resume for approval, registers listeners immediately, sends started/progress/finished events exactly once, and cancels cleanly on destination failure. -- Unit: queued download-started/progress/finished state flushes after guest registration with the latest state. -- Unit: multiple download events for one browser page are tracked independently. -- Unit: guest cleanup cancels queued-but-unbound active downloads and releases reserved paths. -- Unit: tab unregister cancels every active download for that tab and releases reserved paths. -- IPC: remove `browser:acceptDownload` and its native save-dialog test for normal downloads; keep `browser:cancelDownload` authorization coverage. -- Renderer: download list state covers active, completed, failed, canceled, unknown-size, multiple same-tab downloads, bounded recent rows, and missing-file action failures. -- Shell IPC/preload: `Open` uses `openFilePath`; `Show` uses `openInFileManager` and surfaces structured failure. -- Electron validation: from a local test page, click a download link and verify a file appears in the OS Downloads folder without a save dialog. - -## UI Quality Bar - -The changed browser chrome should be quiet and dense, matching the toolbar area around it.

Run targeted unit tests, typecheck, lint, then Electron validation with screenshots. - -## Lightweight Eng Review - -- Scope: Kept to local built-in browser download behavior. Reduced by excluding a preferences UI, persistent download history, and remote-to-local transfer. The smallest useful normal-browser behavior is automatic save to Downloads plus transient progress/completion chrome. -- Architecture/data flow: Main owns destination choice and file writes because Electron requires `setSavePath()` during `will-download`. Renderer owns only display and user actions (`Cancel`, `Open`, `Show`, dismiss). Existing session policy installation remains the entry point; existing shell bridges handle file actions. Browser web clients remain unchanged. -- Failure modes covered: - - Late `setSavePath()` is removed by assigning the path synchronously in `will-download`. - - Duplicate filenames use existing-file checks plus active path reservations instead of overwriting each other inside Orca. - - Unsafe or empty filenames are normalized before `path.join`. - - Downloads starting or finishing before tab registration are snapshotted and flushed in order. - - Queued downloads are canceled if their guest is destroyed or retired before registration. - - Multiple downloads no longer overwrite a single pane state. - - Tab close/app shutdown cancels active items rather than leaving hidden downloads without chrome. - - File action failures after external deletion are surfaced without overclaiming. -- Test coverage required: - - Unit: `src/main/browser/browser-download-destination.test.ts` for basename/suffix/collision/reservation behavior and bounded failure. - - Unit: `src/main/browser/browser-manager.test.ts` for immediate `setSavePath`, listener registration, queued snapshots, progress/finish, cancellation, path-reservation release, and failure. - - Unit/IPC: `src/main/ipc/browser.test.ts` removes the native save-dialog accept path and keeps cancel authorization. - - Renderer: focused tests around download notice/list state if an existing seam is available; otherwise cover formatting helpers and rely on Electron validation for BrowserPane DOM behavior. - - Electron: local server download verifies file creation in Downloads without save dialog. -- Performance/blast radius: No startup cost. Per-download synchronous filesystem checks are bounded by the collision limit and happen only during `will-download`; this is acceptable for one user action but must not walk unbounded directories. Renderer IPC volume stays proportional to Electron download progress events already emitted. No migration. -- UI quality bar: Validation should judge a neutral browser-toolbar-adjacent download row/list against `docs/STYLEGUIDE.md`: no amber error styling for ordinary progress, compact button sizes, no overlap/wrapping, honest copy, clear active/completed/failed hierarchy, and stable layout while progress changes. -- Required review screenshots: - 1. Active download in progress with no save prompt. - 2. Completed download row with `Open` / `Show` actions. - 3. Repeat same-name download completed with distinct filename. - 4. Multiple downloads visible or capped as designed. - 5. Browser toolbar after dismissing download chrome. -- Residual risks: Headless Electron may not reliably prove absence of a native save dialog; validation should instead verify no Orca `Save` prompt appears and the file lands in Downloads. If the OS Downloads path is redirected or unavailable, behavior depends on Electron's `app.getPath('downloads')` result. diff --git a/docs/bug-reproductions/8979-screenshots/after-fable-visible.png b/docs/bug-reproductions/8979-screenshots/after-fable-visible.png deleted file mode 100644 index 0e8d49a8e34..00000000000 Binary files a/docs/bug-reproductions/8979-screenshots/after-fable-visible.png and /dev/null differ diff --git a/docs/bug-reproductions/8979-screenshots/before-fable-hidden.png b/docs/bug-reproductions/8979-screenshots/before-fable-hidden.png deleted file mode 100644 index 4100383237e..00000000000 Binary files a/docs/bug-reproductions/8979-screenshots/before-fable-hidden.png and /dev/null differ diff --git a/docs/claude-fable-weekly-usage-meter.md b/docs/claude-fable-weekly-usage-meter.md deleted file mode 100644 index ae7bcc0f909..00000000000 --- a/docs/claude-fable-weekly-usage-meter.md +++ /dev/null @@ -1,75 +0,0 @@ -# Claude Fable Weekly Usage Meter - -## Problem - -Claude Code now exposes weekly subscription usage alongside the 5-hour window, and its live `/usage` panel can show an explicit Fable-specific weekly bucket.

The existing open-tab list only combines browser and simulator matches in `WorktreeJumpPalette.tsx` (`browserItems`, `simulatorItems`, `openTabItems`). Terminal/editor activation exists elsewhere, notably the shortcut activation path in `src/renderer/src/lib/tab-number-shortcuts.ts`, but Cmd-J has no searchable row for those tab kinds.

Add a focused tab-search helper, likely `src/renderer/src/lib/workspace-tab-palette-search.ts`, modeled after `simulator-palette-search.ts`. It should build searchable entries from `unifiedTabsByWorktree` for terminal tabs and editor-family tabs (`editor`, `diff`, `conflict-review`, `check-details`; markdown preview is an `editor` tab whose `OpenFile.mode` is `markdown-preview`). Do not fold browser/simulator into this helper unless tests prove their current scoring, empty-query comparators, rendering data, and activation behavior are unchanged. - -2. Resolve displayed titles through existing sources: - - Terminal: map the unified terminal tab's `entityId` to `tabsByWorktree[worktreeId]`, then use `resolveTerminalTabTitle` from `src/shared/tab-title-resolution.ts:3` with `settings.tabAutoGenerateTitle`. - - Editor-family tabs: map the unified tab's `entityId` to `openFiles`, then use `getEditorDisplayLabel`, with relative path/full path as secondary searchable text. If the backing `OpenFile` is missing, do not create a searchable editor row; `setActiveFile` cannot safely restore it. - - Terminal fallback: use `resolveUnifiedTabLabel` from `src/shared/tab-title-resolution.ts:17` only when a terminal's legacy `TerminalTab` record is missing but the unified terminal tab still exists. - -3. Add agent-session keywords only from bounded structured state: - - `agentStatusByPaneKey`: `prompt`, `agentType`, `state`, `providerSession.key/id`, `terminalTitle`, and capped `stateHistory[].prompt`. - - `retainedAgentsByPaneKey`: the retained `entry` fields above plus the retained terminal tab title snapshot. - - `sleepingAgentSessionsByPaneKey`: `prompt`, `agent`, `providerSession.key/id`, `state`, and `terminalTitle`. - Attach metadata to a terminal row only when it matches that terminal by explicit `tabId`, by retained `tab.id`, or by pane-key prefix `${terminalTabId}:`, where `terminalTabId` is the legacy terminal id (`unifiedTab.entityId`). The worktree must also match when the record carries one. Do not include terminal scrollback, full assistant messages, `lastAssistantMessage`, `toolName`, or `toolInput`. Keep rendered snippets trimmed/capped even though hook payloads and history length are already bounded. - -4. Rank with predictable field weights: - - Displayed tab title: highest priority. Terminal title precedence must match `resolveTerminalTabTitle`: custom title, quick-command label, generated title only when enabled, raw title, then fallback. Editor title precedence must match `getEditorDisplayLabel`. - - Agent prompt/session metadata: next, shown as supporting text when it caused the match. - - Worktree name and repo name: lower priority, matching browser/simulator ordering. - - Empty query: preserve current behavior by showing open tab rows. Existing browser/simulator helpers compute context-first scores, but `WorktreeJumpPalette` currently merges all open-tab item types by `result.score` and then item id; do not replace that final merge comparator unless tests deliberately cover the browser/simulator ordering change. New terminal/editor rows should encode deterministic context-first ordering in their scores: current tab, current worktree, worktree order, then group/tab order. Browser/simulator already index across all worktrees, including archived/default-hidden worktrees; terminal/editor rows may follow that open-tab behavior, but only for rows backed by existing unified tabs. - -5. Integrate in `WorktreeJumpPalette.tsx` with a small new `WorkspaceTabPaletteItem` type and helper import. Add explicit store selectors for the new inputs (`openFiles`, `retainedAgentsByPaneKey`, `sleepingAgentSessionsByPaneKey`, `activeTabId`, `activeTabIdByWorktree`, `activeFileId`, `activeFileIdByWorktree`, and `activeTabTypeByWorktree` for current-row detection). Replace `openTabItems` with browser + simulator + workspace tab items sorted by the existing combined open-tab ordering, keeping the existing `OPEN TABS` section and caps. - -6. Add a generic tab activation helper, likely `src/renderer/src/lib/workspace-tab-palette-activation.ts`, that mirrors `activateTabNumberShortcut` (`src/renderer/src/lib/tab-number-shortcuts.ts:57`) and existing simulator selection (`src/renderer/src/components/WorktreeJumpPalette.tsx:1090`). Re-resolve the target from `useAppStore.getState()` at selection time before mutating state: - - `activateAndRevealWorktree(worktreeId)`. - - Verify the target worktree, group, and unified tab still exist; the tab must still have the expected content type and still belong to the target worktree/group. Return with the same toast pattern before mutating state if any of those checks fail. - - Terminal: activate web runtime session when needed using `getRuntimeEnvironmentIdForWorktree`, `isWebRuntimeSessionActive`, and `activateWebRuntimeSessionTab`; set `activeTab` to terminal `entityId`; set active type to `terminal`; then `focusTerminalTabSurface(entityId)`. - - Editor-family tabs: verify `openFiles` still contains `entityId`; focus the target group, set active file to `entityId`, activate the unified tab id, then set active type to `editor`. Activating after `setActiveFile` preserves the specific split tab and is required for `check-details`, which `setActiveFile` does not implicitly re-find. - - Simulator/browser behavior should remain unchanged unless the shared helper explicitly preserves existing semantics. - -7. Render terminal/editor rows with the existing open-tab row density and tokens near `src/renderer/src/components/WorktreeJumpPalette.tsx:1697`: icon, highlighted title, current-tab/current-worktree chip, supporting text, worktree, host badge, and repo badge. Use existing icons (`SquareTerminal`, `FileText` or file-type icon if cheap and already available). Update the no-results subtitle at `src/renderer/src/components/WorktreeJumpPalette.tsx:1385` to include tab title/agent prompt without making it verbose. - -8. Keep generated lists computed in `useMemo`; all required source data already exists in the renderer store, but `WorktreeJumpPalette` must subscribe to the slices it does not currently read. No new IPC, polling, filesystem reads, persistence fields, or shared mutable cache are needed. Search work should stay proportional to open unified tabs plus the small in-memory agent maps. - -## Data flow - -- Store slices expose `unifiedTabsByWorktree`, `tabsByWorktree`, `openFiles`, worktrees/repos, live agent statuses, retained agents, sleeping sessions, active group ids, and active terminal/editor ids. -- `buildSearchableWorkspaceTabs(...)` produces one entry per open terminal/editor tab with resolved labels and bounded agent keywords. -- `searchWorkspaceTabs(entries, query)` returns scored/highlighted results. -- `WorktreeJumpPalette` maps results to open-tab rows. -- User selects a row. -- Selection re-resolves the target from the live store, activates the owning worktree/group/tab, and focuses terminal/editor as appropriate. - -## Edge cases - -- Custom title, quick-command label, generated title, and raw title should follow the same precedence as the tab bar. -- Generated titles disabled: do not make generated terminal/unified labels the displayed title or a title-weighted match. It is acceptable to search bounded agent prompt/session metadata regardless of this setting. -- Split groups: activate the result's `groupId`, not just the worktree's last active group. -- Terminal unified tab missing its legacy terminal record: still show a fallback title from the unified tab and navigate if the unified tab exists. -- Editor-family unified tab missing its `OpenFile`: omit the row and treat selection as stale if it disappears after search. -- Markdown preview tabs: include them through `contentType: 'editor'` and `getEditorDisplayLabel`; do not look for a separate unified content type. -- Current-row detection is type-specific: terminal active ids are legacy terminal ids, editor active ids are file ids, while unified group state stores unified tab ids. -- Agent pane keys are composite `${tabId}:${leafId}`; only attach agent metadata when it is attributed to the result tab by explicit `tabId`, retained `tab.id`, or pane-key prefix and does not conflict with record `worktreeId`. -- Multiple agent panes in one terminal tab: include all bounded agent prompts/metadata, but show only the best matching supporting snippet. -- Sleeping sessions: search metadata only when tied to an existing terminal tab; selecting the row must navigate to that tab and must not call resume/launch logic, regardless of `origin`. -- Archived/default-hidden worktrees: preserve current open-tab search behavior by indexing open tabs across all worktrees. -- SSH/web runtime tabs: activation must call the existing runtime activation path where terminal/browser tab shortcuts already do. -- One-character query: keep the existing two-character minimum only for settings/actions; open-tab search follows current browser/simulator tab search behavior and may match one character. -- Stale records: ignore agent records whose tab id cannot be tied to an existing open tab; do not create standalone agent-session rows. -- Duplicate metadata from live + retained + sleeping records: de-duplicate by pane key and prefer live, then retained, then sleeping for keywords/supporting snippets. -- External mutations during selection: if the target tab, backing `OpenFile`, group, or worktree disappeared after search, close nothing and show the same toast-and-return pattern used for missing browser/simulator rows. Validate all of these before calling `focusGroup`, because `focusGroup` itself will stamp the requested group id even if the group was removed. - -## Test plan - -- Unit: add `workspace-tab-palette-search.test.ts` covering terminal title precedence, generated-title disabled behavior, editor label/path search for every editor-family content type and markdown preview mode, agent prompt/session search, retained/sleeping metadata attribution by legacy terminal id, stale/orphan metadata exclusion, split-group current-tab detection, and deterministic ordering. -- Unit: update/add `WorktreeJumpPalette` tests only if there is an existing lightweight component harness; otherwise cover integration behavior through pure helper tests and targeted activation helper tests. -- Unit: add activation tests for a helper if extracted from `WorktreeJumpPalette`, including terminal web-runtime activation, editor-family activation for `editor`/`diff`/`conflict-review`/`check-details`, missing tab/group/backing-file/worktree failures, and split group focus. -- Regression: ensure existing `simulator-palette-search.test.ts` and `palette-results.test.ts` still pass. -- Validation: Electron golden path for searching a terminal tab title/agent prompt and selecting it, plus an editor-family tab selection; adjacent smoke for existing browser/simulator open-tab rows. - -## UI Quality Bar - -User-visible. The new rows must look like the existing Open Tabs rows: same spacing, typography, selection state, highlight weight, badges, truncation, host/repo badges, and row density.

Dispatch wiring — both layers - -- **Main** (`src/main/window/createMainWindow.ts`): instantiate a - `ModifierDoubleTapDetector` per window. In `before-input-event`, feed every - `keyDown`/`keyUp` to the detector (it only consumes bare-modifier events). On - emit, build the synthetic input `{ doubleTapModifier: M }`, run the existing - `resolveWindowShortcutAction(syntheticInput, platform, keybindings, - terminalShortcutContext)`, and if an allowlisted action resolves, dispatch via - the current IPC + `preventDefault()` path. `resolveWindowShortcutAction` needs - no per-action change; the implicit numeric-index shortcuts are guarded on - `input.key`, which is undefined for a double-tap input, so they cannot match. - Only the emitting second-keydown event is `preventDefault()`-ed — never the - first tap's down/up (those bare modifiers are harmless and the keyup is needed - by the detector). -- **Renderer** (`src/renderer/src/App.tsx`): extract the body of the window - `onKeyDown` handler into `dispatchShortcutInput(input: ShortcutDispatchInput)`, - where `ShortcutDispatchInput` exposes the modifier/key fields plus - `doubleTapModifier?`, a `preventDefault()` (no-op for synthetic input), - `defaultPrevented`, and the focus/target context. The real listener wraps the - `KeyboardEvent`; a renderer `ModifierDoubleTapDetector` (fed by both a keydown - and a **new** keyup window listener) produces a synthetic input on emit with - `context` derived from `document.activeElement`, and calls - `dispatchShortcutInput`. - -#### No double-fire between layers - -This reuses the exact disambiguation normal shortcuts already rely on: - -- For an **allowlisted** action, main detects the double-tap on the second - modifier keydown, resolves it, and calls `preventDefault()`.

The - suppressed second keydown never arrives, but its keyup still does — a keyup of - the armed modifier with no intervening second keydown clears the armed state, - so a later lone press of the same modifier cannot phantom-complete the gesture.) -- For a **non-allowlisted** action, main's detector still emits but - `resolveWindowShortcutAction` returns `null`, so main does not call - `preventDefault()`. The second-keydown DOM event reaches the renderer, whose - detector completes and fires via `dispatchShortcutInput`. - -### 5. Recorder UX — `ShortcutBindingRow.tsx` + `ShortcutsPane.tsx` - -The recorder currently captures on the first keydown, which makes a bare -modifier error with "Press a key, not only a modifier."

Without that, a closed row can remain visible until a later refetch. - -## Edge Cases - -- Duplicate target is blank, zero, negative, decimal, or the same issue number: keep the picker open and show inline validation after Enter. -- Duplicate target can be a different repository's issue only when the implementation accepts a URL; this pass takes a loaded same-repository issue or number, so validation and copy should describe it as an issue in the same repository. -- The row refreshes while the menu is open: reconcile the optimistic draft before paint as the current status cell already does. -- Rapid repeated choices: retain the existing request id guard so stale responses cannot revert a newer choice. -- SSH/runtime target: payload must remain serializable and use the existing runtime method. -- Multi-window consistency: do not assume another window's in-memory `workItemsCache` observes the optimistic patch.

Add an `applyZoomChange(fn)` wrapper inside `ImageViewer` that uses functional `setZoom`, and reset `zoom` to `1` when `filePath`, `mimeType`, or `cleanedContent` changes. `EditorContent` can reuse the same `ImageViewer` component position across image files, so local zoom must not accidentally carry across file switches or external reloads. -3.

The target ID is immutable; ownership and active-last ordering are resolved again from current state immediately before cleanup. - -### 2. Keep daemon shutdown semantics, then close the snapshot - -Call the existing `window.api.pty.management.killAll()` once. After it settles, resolve the still-present targets and deduplicate their current `ptyIdsByTabId` entries. These are the renderer's current binding ownership records, not independent liveness proof; do not pull IDs from `tab.ptyId`, deferred SSH restore state, or `terminalLayoutsByTabId.ptyIdsByLeafId`, which can be restore hints rather than current ownership. - -Force-close every snapshotted surface through `closeTerminalTab(id, { force: true })`, then await one existing `window.api.pty.kill(id)` call for each captured non-`remote:` PTY ID. Run both phases for management success, partial success, and IPC rejection because the confirmation explicitly covers closing the terminal surfaces. Use per-target/per-PTY settlement so one unexpected store or provider failure does not stop the remaining cleanup. Already-gone PTYs are successful no-ops in the main handler; other exact-kill rejections are reported separately. - -Close targets outside the cleanup-time `activeWorktreeId` first and targets currently owned by it last. A tab moved into the active worktree or a workspace selected while the daemon call was pending must therefore move to the last partition. Let `closeTerminalTab` choose the existing post-state for the last local terminal: editor, then browser, then `setActiveWorktree(null)`. Do not pre-clear `activeWorktreeId`; the sleep flow needs that ordering because it leaves tab records mounted while clearing PTYs, whereas this flow removes the tabs. Add active-switch and active-last regression tests and only adopt sleep-intent/deactivate-first if those tests prove a respawn. - -This is not one backend call end-to-end. The coordinator issues one daemon-management IPC, one renderer close per unique target, and at most one exact kill IPC per unique current non-runtime PTY binding. The explicit exact kills make local/SSH shutdown requests settle before caller refresh instead of relying on React unmount timing. A mounted transport may race that request and issue an idempotent duplicate during unmount; count that separately in live performance evidence. A still-bound daemon session can receive the exact retry after the management poll, so daemon toast counts remain the management handler's earlier reported snapshot, not final process truth. Runtime-hosted tabs additionally issue one `session.tabs.close` flow per tab. - -The coordinator must live outside the hook (for example, `kill-all-terminal-surfaces.ts`) and must not gate cleanup on `mountedRef`. Navigating away or unmounting the invoking popover/settings component while IPC is pending does not revoke an already confirmed destructive action; only React callbacks and hook state updates remain mount-gated. - -### 3. Do not add a post-kill orphan sweep - -Do not call `pty.listSessions()` and kill everything returned after the management call. Exact kills captured from `ptyIdsByTabId` for the immutable target surfaces are allowed and required; they do not discover or cross into unrelated sessions. - -The management handler already targets daemon orphans in its initial snapshot. A later broad sweep would cross the confirmation boundary by killing local/SSH sessions or fresh sessions created while the existing poll was running. It would also add provider inventory fan-out to a recovery action and conflict with the main handler's initial-ID accounting. - -The existing explicit **Kill orphan terminals** action remains separate. - -### 4. Make completion and failure copy honest - -Have the renderer cleanup return a bounded summary: target count, targets absent at completion, failed close attempts, exact PTY kill requests accepted/rejected, and daemon result/error. Verify absence in both terminal and unified state after each close attempt. Toasts must report renderer cleanup separately from daemon counts; do not show **No sessions running** when terminal tabs were closed. - -Because the management API suppresses adapter-list failures, copy must describe daemon counts as reported, not claim that every daemon process was verified dead. Returning adapter errors is a follow-up unless this PR chooses to widen the API. Exact `pty.kill` rejection counts may be stated as failed shutdown requests, not as proof that the processes remain alive. - -Examples of states, not required wording: - -- all daemon targets were reported exited, exact shutdown requests were accepted, and tabs closed: success; -- `remainingCount > 0`: warning that management reported daemon processes not exited before exact binding cleanup; -- management IPC rejected: error that tabs closed, with daemon shutdown unverified and any exact PTY kill failures called out; -- no daemon sessions and no terminal tabs: existing informational state. - -Run `onKillAllSettled` only after surface removal and exact PTY kill settlement. `closeTerminalTab` returns before React unmount effects run, so surface removal alone is not a sufficient boundary for Resource Manager's `pty.listSessions()` refresh. Keep one confirmation dialog and update its description to say that terminal tabs across workspaces close and unsaved terminal work is lost. - -### 5. Provider limits - -`closeTerminalTab` synchronously prunes host-backed local mirrors but currently returns `void` and discards the promise from `closeWebRuntimeSessionTab`. The underlying helper is already awaitable: its close request has a 15-second timeout and, after success, it awaits an eager list refresh with another 15-second timeout. Its boolean can therefore settle after roughly 30 seconds, while close-intent suppression expires after 10 seconds. This change must not claim verified runtime-host completion unless the bulk helper propagates that existing result and aligns the intent lifetime. - -For this Windows/local bug, runtime-host cleanup is best-effort and an explicit accepted gap. A follow-up may propagate the existing async close result through terminal-tab actions and align the RPC timeout/intent lifetime. SSH must be exercised if the fixture is available; otherwise record live SSH process absence as an accepted gap. No provider-specific local filesystem or process assumptions are added. - -## Data flow - -```text -confirm - → snapshot unique terminal surface IDs - → pty.management.killAll() daemon current + legacy; existing polling - → resolve current target ownership + bound PTY IDs - → close snapshotted tabs, active last renderer/xterm cleanup; runtime-host close starts - → await exact non-runtime pty.kill IDs local/SSH acknowledgement; no provider sweep - → toast daemon result + surface/exact-kill summary - → caller refresh -``` - -## Concurrency and consistency - -| Case | Required behavior | -| ----------------------------------------- | ----------------------------------------------------------------------------------------------------------------- | -| No daemon sessions; dead/empty tabs exist | Close target tabs and report tab cleanup, not “No sessions.” | -| Daemon session refuses to exit | Close the confirmed tab; report that management saw it remaining before the exact retry.

Provider inventory absence is live validation, not the renderer-unit oracle. -- **Diagnostics:** emit one content-free bounded summary with target/absent/failed-close counts, exact-kill accepted/rejected counts, and the daemon result or error.

The existing management call can wait for 65 sleeps plus adapter latency. The coordinator adds at most one existing exact-kill IPC per unique current non-runtime PTY binding; record both those calls and any idempotent unmount duplicates as part of the performance evidence. - -Repeated `closeTerminalTab` calls are not O(tabs): target resolution and store cascades scan/clone multiple maps per close, so worst-case renderer work is superlinear. Measure the synchronous close phase with a representative high-tab fixture (at least 100 terminal tabs). Record close attempts, Zustand writes, duration, and long tasks. If it creates a >50 ms renderer task, add a focused bulk reducer or yield-safe batching rather than declaring the rare action free. - -For resource reclamation, prefer deterministic counts: zero target `TerminalPane`/xterm instances, released listeners/transports, and no initial PTY IDs. A repeated open/kill cycle may supplement this with heap/working-set evidence, but absolute memory deltas are not a stable pass/fail oracle. - -## UI quality bar and screenshots - -No new layout or visual token is needed. Keep the existing shadcn `Dialog`/destructive `Button`, compact typography, dismissal lock while busy, and accurate consequence-first copy. The post-state must never be a blank/crashed TerminalPane or a wall of dead empty panes. - -Required review screenshots: - -1. Resource Manager before kill with an empty terminal and an established terminal visible in the workspace. -2. Resource Manager kill-all confirmation with updated close-tabs copy. -3. Matched post-kill workspace showing target terminal tabs gone and refreshed counts. -4. Manage Sessions confirmation or post-state, proving the second entry point uses the same behavior. - -## Lightweight Eng Review - -- **Scope:** renderer surface cleanup layered on the existing daemon management action; no daemon redesign and no broad orphan/provider sweep. -- **Architecture/data flow:** main owns its initial daemon-session shutdown; renderer owns the confirmed terminal-surface snapshot, exact current-binding shutdown, and tab/xterm disposal; runtime-host close remains behind existing routing. -- **Failure modes:** partial/rejected daemon kill, exact provider-kill failure, no-session cleanup, pinning, splits, cleanup-time active selection, new/moved/disappeared tabs, same-tab rebind, overlapping actions, invoking-component unmount, stale runtime snapshots, adapter-list uncertainty, and future multi-window ownership are explicit above. -- **Tests:** deterministic state/coordinator and main-handler tests plus Windows Electron proof; a new experimental partial reliability gate records provider gaps. -- **Performance/blast radius:** one existing management IPC, bounded exact per-PTY kill IPCs, no new listing/polling, but N close cascades require measurement because current helpers are not linear or atomic. -- **UI quality bar:** existing dialog primitives and truthful copy; screenshots prove both entry points and the terminal-free post-state, not memory reclamation. -- **Residual risks:** daemon adapter listing can stall until client timeouts and failures are treated as empty; terminal-tab actions discard the runtime-host close result and its 10-second intent is shorter than the possible two-request close flow; a binding created after exact-ID capture is killed only by transport unmount; live SSH/WSL/mobile behavior may remain accepted gaps until fixtures prove it. - -## Rollout - -1.

Do not let the renderer cache a request under limit 72 while the backend silently serves 50. - - Main `listIssues` should clamp/floor its own `first` value too, so direct callers and future RPC paths cannot send unbounded GraphQL reads. - - Keep project/custom-view clamps unchanged unless this feature explicitly expands those lists too. - -3. Compute `hasMore` accurately. - - For each workspace result, set `hasMore` from the connection `pageInfo.hasNextPage`. - - For any multi-workspace plain-list read, also set `hasMore` when the merged, sorted list is clipped to the effective limit.

The current shared in-flight type is `Promise`, which will be wrong once only list reads return an envelope. - - Keep cache identity based on workspace, filter, and the effective clamped limit. Compute that effective limit before request signatures and cache keys; do not key a request by an unclamped value that the backend will silently reduce. - - Existing generation and in-flight entry checks protect cache writes for the same key, but different limits are different keys. `TaskPage` still needs a latest-request guard so a slower 36-row promise cannot replace a newer 72-row window in component state. - - Update `getCachedLinearIssues` or add a collection-aware cached read so `TaskPage` can keep existing rows visible while a larger window loads. - - If plain lists keep using `linearSearchCache`, update every array-shaped consumer of that bucket, including `findTaskPageLinearIssue` and its `LinearSearchCache` alias in `task-page-cache-selectors.ts`, `patchLinearIssue`, and any `LinearSearchCache`/`LinearIssueReadArgs` test helpers.

Fix team-list completeness. - - `src/main/linear/teams.ts` currently calls `entry.client.teams()` once per workspace. The SDK query is paginated, so this can omit teams in larger workspaces. - - Fetch all pages before the selector relies on team absence as a meaningful signal. Use `teams({ first })` plus `fetchNext()` until `pageInfo.hasNextPage` is false, or an equivalent raw GraphQL query. Keep the existing `MAX_CONCURRENT` limiter and do not set `includeArchived`; retired teams should stay absent. - -2. Invalidate caches when a Linear key is connected or replaced. - - Replacing a team-limited key with a full-access key must not leave the old `linearTeamCache` visible for up to `TEAM_CACHE_TTL`. - - On successful `connectLinear`, synchronously clear Linear issue/search/team caches, in-flight issue/search/list/team requests, and metadata. Do this before publishing success, then await a forced status refresh before resolving so callers see the selected workspace and workspace list that came from the new key. The renderer `linearConnect` result is typed as `{ viewer }` only; do not rely on the main-process-only `workspace` field. - - Guard `fetchLinearIssue()` and `listLinearTeams()` cache writes with a request generation or entry identity check. Clearing their in-flight maps is not enough today: those promises write unconditionally after resolution and can repopulate old issue/team data after key replacement. `searchLinearIssues()` and `listLinearIssues()` already use in-flight entry identity checks for forced refreshes; keep them covered by the same generation if connect/disconnect clears their maps. - - Force a team refetch for the selected/connected workspace if the Linear Tasks view is open. - - Issue list caches also need invalidation because changing key scope can add or remove visible issues. - -3. Handle auth-driven token removal explicitly. - - Backend calls can clear a workspace token on auth errors. In `all` workspace mode, `listTeams()`, `listIssues()`, and `searchIssues()` may return partial results instead of throwing. - - After any auth-driven clear, the renderer must get a forced Linear status refresh or a typed signal so disconnected workspaces disappear without waiting for a later manual check. The current array-returning issue/search/team APIs have no signal for `all`-mode partial auth clears, so either add an auth-cleared result envelope end-to-end or force a metadata-only status refresh after `all`-workspace issue/search/team reads. Do not set `linearStatus` to globally disconnected from a single request error; refresh status because multi-workspace failures may only remove one workspace. - - Strengthen `checkLinearConnection()` status equality. It currently compares workspace count, effective selected id, connected state, and viewer email. It misses active workspace id and workspace metadata changes when the count is unchanged. Compare a stable workspace signature including id, organization id/name/url key, display name, and email. - - When a forced status refresh observes a changed selected workspace or workspace signature, clear issue/search/team caches, in-flight issue/search/list/team requests, and metadata. `checkLinearConnection()` currently only updates `linearStatus`, so removed workspaces can leave stale rows in `all` caches. - -4. Be honest about team filtering. - - Current Linear issue reads do not accept team IDs; team selection filters the already-limited issue/search result in the renderer after the `LINEAR_ITEM_LIMIT` page arrives. In `all` workspace mode, each workspace may fetch up to the limit, but the backend aggregates and trims back to `LINEAR_ITEM_LIMIT` before the renderer filters by team. - - This UI change should not imply exhaustive server-side team scope. Empty task states must say no fetched/current issues match the selected teams. True server-side team scoping needs a separate change to add team IDs to cache keys, runtime RPC params, and Linear GraphQL filters. - -## Design - -1. Add URL helpers in `src/shared/linear-links.ts`. - - `buildLinearPersonalApiKeySettingsUrl(organizationUrlKey?: string | null)` returns `https://linear.app//settings/account/security` when a slug exists, otherwise `https://linear.app/settings/account/security`. - - `buildLinearWorkspaceApiSettingsUrl(organizationUrlKey?: string | null)` returns `https://linear.app//settings/api` when a slug exists, otherwise `https://linear.app/settings/api`. - - Encode path segments consistently with `buildLinearTeamUrl`. - -2. Add `LinearApiKeyDialog` in `src/renderer/src/components/linear-api-key-dialog.tsx`. - - Props: `open`, `onOpenChange`, optional `workspace`, optional `title`, optional `description`, optional `connectLabel`, optional `onConnected`, optional `overlayClassName`/`contentClassName`. - - Own input, connecting/error state, Enter-to-submit, and `connectLinear`. Fire `onConnected` only after `connectLinear` resolves with refreshed store status. - - Use org-specific URLs only when a single workspace context is known. For `all`, use the global fallback and copy that tells the user to choose the intended Linear workspace. - - Guidance: - - Create a Personal API key from Account > Security & Access. - - Prefer full access when Orca should show every team the account can access in that workspace. - - If member API keys are blocked, ask a workspace admin to allow them from workspace API settings. Do not imply the workspace API page creates the personal key. - - A key never grants teams the owner cannot access. - - Make storage copy runtime-aware. Local runtime keys use the local OS keychain when Electron encryption is available; SSH/remote-runtime keys are stored by that runtime, not necessarily on this machine. - -3. Replace the Tasks toolbar Linear controls with `LinearScopeSelector`. - - Suggested file: `src/renderer/src/components/linear-scope-selector.tsx`. - - Keep state updates in `TaskPage`: workspaces, selected workspace id, teams, selected team ids, callbacks for workspace select, team select, select-all teams, open selected team URL, and open API-key dialog. - - Trigger label examples: - - One workspace + sticky-all: `All teams` - - One workspace + subset: `ENG, STA +1` - - Multiple workspaces + `all` + sticky-all: `All workspaces` - - Multiple workspaces + one workspace + sticky-all: ` / All teams` - - Multiple workspaces + subset: ` / ENG, STA +1` or `All workspaces / ENG +1` - - If the active scope is `all` and selected team keys are duplicated or span multiple workspaces, prefer `All workspaces / 2 teams` over an ambiguous key list. - - Popover content: - - Search filters team rows by team name, team key, and workspace name. - - Workspace section appears only when more than one workspace is connected. It includes "All workspaces" and each workspace. - - Selecting a workspace must call the existing `selectLinearWorkspace` flow, clear selected issue/list/error/loading state the same way `TaskPage` does now, and must not mutate `defaultLinearTeamSelection`. - - Team section includes "All teams" and selectable team rows. "All teams" persists `defaultLinearTeamSelection: null`; explicit subsets persist an array. Normalize a selection equal to all available teams back to `null`, even if the user selected teams one by one. Never persist an empty array; keep the last team selected or save `null`. - - Team rows show name, key, and workspace name when active workspace is `all` or when multiple workspaces exist. - - Footer has "Add team access" with a key/link icon. Close the popover before opening the API-key dialog. - - Keep the external-link button as an icon-only sibling. It remains an action, and should stay enabled only when exactly one selected team has a URL. - -4. Keep team selection reconciliation, but document its limits. - - `reconcileLinearTeamSelection()` preserves sticky-all and drops stale team IDs. - - Because the saved team subset is global, switching workspaces may temporarily select all teams in the new workspace while preserving the old saved subset for later. Do not introduce per-workspace persistence here. - -5. Update Settings and onboarding to use `LinearApiKeyDialog`. - - Rename "Add workspace" to "Add Linear access" when disconnected and "Update access" or "Add workspace access" when connected. - - Replace "Each workspace uses its own locally stored API key" with copy that says each connected Linear workspace has one key stored by the active runtime; a full-access key can cover all visible teams in that workspace, and a restricted key can be replaced any time. - - Keep existing per-workspace Test and Disconnect controls. - -## Edge Cases - -- No Linear workspaces connected: no Tasks selector; Settings/onboarding still show Connect. -- One workspace connected: hide the workspace section, but keep "Add team access" visible. -- Multiple workspaces + `all`: team keys/names can repeat across workspaces; always show workspace names in rows. -- Empty team result: show an empty state plus footer action. Do not claim the key is the only possible cause; absence can also come from private-team membership, archived teams, permissions, or a fetch failure. -- Empty issue result after team selection: say no fetched/current issues match the selected teams. Do not imply Linear was queried exhaustively for those teams. -- Legacy or missing `organizationUrlKey`: use global Linear settings URLs and keep the paste flow usable. -- Replacement key for an existing workspace: select that workspace, invalidate caches, refresh status, and refetch teams immediately. -- Auth errors: a backend call may clear a token. The selector must tolerate stale rows during the refresh, then drop disconnected workspaces when status updates. -- Multi-window/external mutations: there is no real-time renderer broadcast. Force `checkLinearConnection(true)` after connect/disconnect/test flows and when opening the selector if stale status would be visible. Forced refresh must still update state and invalidate caches when workspace metadata changed but the workspace count did not. A same-workspace key replacement with identical viewer/workspace metadata is invisible to status today; do not claim that case is handled unless this change adds a non-secret credential revision or a renderer broadcast. -- Remote runtime/SSH: continue routing through `connectLinear`, `selectLinearWorkspace`, `listLinearTeams`, and runtime RPC. Do not call local Electron APIs directly except for opening Linear URLs. -- Accessibility: trigger is a combobox-style button, rows are keyboard-selectable, icon buttons have labels/tooltips, and the dialog traps focus. - -## Tests - -- `src/shared/linear-links.test.ts`: URL helpers, fallback behavior, and path encoding. -- `src/main/linear/teams.test.ts`: paginated team fetching and `all` workspace aggregation. -- `src/renderer/src/store/slices/linear.test.ts`: successful connect invalidates issue/search/team caches, drops stale in-flight writes, awaits refreshed status, and does not mark all Linear disconnected for one workspace auth failure. -- `src/renderer/src/store/slices/linear.test.ts`: forced status refresh detects changed workspace ids/metadata with the same workspace count and invalidates Linear caches when the scope signature changes. -- Component-independent label and selection-persistence helper tests for `LinearScopeSelector`, including selecting every visible team persisting sticky-all (`null`) rather than a frozen full-team array. -- Avoid brittle popover DOM tests unless matching an existing selector test pattern. - -## Rollout - -1. Fix backend/store correctness: team pagination, connect invalidation, and auth-clear status refresh. -2. Add Linear settings URL helpers and tests. -3. Add `LinearApiKeyDialog`; migrate Settings, onboarding, and the existing Tasks connect dialog. -4. Add `LinearScopeSelector` and replace only the Linear toolbar selector block in `TaskPage`. -5.

Verified end-to-end causal chains + +### S1 — Resume dead-ends on the host index page + +1. Home renders the Resume card only once `hostStates[lastVisited.hostId] === 'connected'` + (`app/index.tsx:488`); over relay that is seconds after the host list paints, and the card + inserts **above** the Tasks card in the same footer (`app/index.tsx:733-780`) — a layout shift + under the thumb. +2. Tap → bare `router.push(createMobileSessionHref(...))` (`app/index.tsx:740-746`) targeting + `/h/[hostId]/session/[worktreeId]`. +3. With the `h` group cold (cold start, or host never visited this session), Expo Router resolves + the push to the host stack's **index route with no `hostId` param**. This exact failure mode is + documented twice in-repo ("cold Expo deep links resolve to index" — + `src/transport/host-edit-navigation.ts:52`, `src/tasks/mobile-task-navigation.ts:90`) and is the + root cause named by PR #12001. +4. `app/h/_layout.tsx:64` reads `hostId` via `useGlobalSearchParams` → `undefined`. + `HostProtocolGate` gets `hostId: undefined`; `useHostClient(undefined)` returns + `state: 'disconnected'` (`src/transport/client-context.tsx:344`) → **grey dot**. +5. The host index screen renders the fallback title `'Host'` (`app/h/[hostId]/index.tsx:821`), and + every fetch no-ops on `!client || connState !== 'connected'` + (`app/h/[hostId]/index.tsx:298,364,418,520`) → **empty list**. The Filter/Recent/Repo chips are + static toolbar UI, so the page looks "real" but dead. +6. "Sometimes": a warm host stack resolves the same push correctly, so the bug is intermittent by + navigation history. + +Corrections to the preliminary sweep: the empty page is primarily the missing `hostId` param, not +the connection-gated fetches or the cold 30s worktree cache (those matter only when landing *with* +a valid `hostId`, e.g. the mistap-strand case). Also, the Resume target "validation" is weaker than +it looks: `getCachedWorktrees` is seeded from the persisted home snapshot at hydration +(`app/index.tsx:264-277`) and the 30s TTL is stamped at seed time (`src/cache/worktree-cache.ts:20`), +so a worktree deleted while the phone was off still passes until a live `worktree.ps` overwrites it. + +**Fix**: PR #12001 ("open the Resume workspace through a mounted host stack") routes Resume through +the same mount-then-replace mechanism Tasks uses, extracted to `src/navigation/host-stack-navigation.ts`. +Reviewed and validated per Jinwoo; **merged to main as `7948e46db855`** after final validation +(see §4, F0). Residual S1 items it does not cover: bare notification/accounts/deep-link pushes (F4), +catalog validation + not-found bounce (F7), Resume-card layout shift (F8), gate unmount hazard (F9). + +### S2 — grey blink when focusing a healthy relay host + +1. Every focus of the host screen fires `notifyForeground()` + (`app/h/[hostId]/index.tsx:512-517`, deliberately empty deps). +2. `openHostLogicalClient` wraps that into `endpointLifecycle.setForeground(true)` + (`src/transport/host-logical-client.ts:31-33`); the lifecycle forwards without dedupe + (`src/transport/mobile-endpoint-lifecycle.ts:62-64`). +3. `MobileEndpointSupervisor.setForeground(true)` computes `wasForeground = true` and calls + `RelayReconnectController.handleForeground` (`src/transport/mobile-endpoint-supervisor.ts:115-119`). +4. `handleForeground` with `wasForeground && state === 'connected'` **suspends the healthy session** + (`src/transport/mobile-relay-reconnect-controller.ts:53-60`). `suspendActiveRelay` early-returns + unless the active path is `'relay'` (`:77-84`) — which is why LAN hosts never blink. +5. `suspendActiveSession` closes the physical session, disposes all subscriptions, and publishes + `'disconnected'` (`src/transport/stable-logical-rpc-client.ts:164-180`) → grey dot + (`src/components/StatusDot.tsx:11`), worktree queries blocked. +6. `onRetry()` → `recoverRelay()` → `openRelay` + `migrateTo`. During the dial the logical state + **stays 'disconnected'**: `migrateTo` only binds the new session's state after + `waitForAuthenticated` resolves (`src/transport/stable-logical-rpc-client.ts:188,213`), and the + dialing session's own `connecting`/`handshaking` publishes (`src/transport/mobile-relay-rpc-session.ts:43,74`) + fire with no listeners attached. Grey persists the full 1–2s (happy path has no artificial + delays; any failure adds ≥250ms full-jitter backoff, `src/transport/mobile-relay-retry-delays.ts:3-5`). +7. `migrateTo` completes → `'connected'` → green; subscriptions replay; gated fetches rerun. + +Second trigger for the same path: OS network-revival nudges call `notifyForeground()` on every live +client (`src/transport/client-context.tsx:286-292`, `src/transport/connection-revival-triggers.ts`) +— any Wi-Fi↔cellular transition or came-online event grey-blinks every connected relay host. + +Design context: the suspend-on-repeat-foreground is pinned by the supervisor test as the +network-handoff half-open case (`src/transport/mobile-endpoint-supervisor.test.ts:~160-197`). The +asymmetry is that **direct sockets probe instead of tearing down** — `notifyForeground` on a +connected direct client runs an activity probe that detects a half-open socket in ≤8s +(`src/transport/rpc-client.ts:1119-1124`) — while relay sessions have a no-op `notifyForeground` +(`src/transport/mobile-relay-rpc-session.ts:106`) and the supervisor's only tool is +suspend-then-redial. There is also an in-repo make-before-break precedent: lease rotation calls +`recoverRelay(forceReplacement = true)` and migrates a **live** session with zero visible blink +(`src/transport/mobile-endpoint-supervisor.ts:56-59,146,249`). + +Divergent mount defaults (secondary): home renders `hostStates[id] ?? 'connecting'` (amber, +`app/index.tsx:707`) while `getState()`/`useHostClient` return `'disconnected'` (grey) for a +missing store entry (`src/transport/client-context.tsx:221,344`) — so host screens flash grey +during the async client acquire (Keychain read) that home never shows. + +### S3 — silent 5–10s relay-forced pairing + +Pairing phase: + +1. `pair-confirm.tsx` / `pair-scan.tsx` pass `connectOptions.onLog` into `startPreProfilePairing` + (`app/pair-confirm.tsx:91-99`, `app/pair-scan.tsx:135-143`). +2. The coordinator threads it **only to the direct candidate** + (`src/transport/pre-profile-pairing-coordinator.ts:152-157`). The relay candidate + (`:161-187`) gets nothing: `connectMobileRelayForPairing` has no log parameter at all + (`src/transport/mobile-relay-physical-client.ts:22-30`), nor do the director resolution, + journal writes, or the recovery loop in `src/transport/pairing-relay-candidate.ts`. +3. With LAN unreachable, the visible "Pairing log" shows only the direct dial stalling toward its + 12s connect timeout while the relay path does the real work silently: cell WebSocket + E2EE + handshake + `pairing.provisionRelay` + `pairing.getEndpoints` + credential-bundle write + (`pre-profile-pairing-coordinator.ts:206-233`). The error copy even says "see log below for + where it stalled" (`app/pair-confirm.tsx:138`) — the log cannot show it. +4. Un-logged waits in the relay recovery loop: each of up to 3 attempts wraps a 5s director + resolution (`src/transport/mobile-relay-invite-director.ts:16`) plus full-jitter sleeps capped + at 100/200/400ms (`src/transport/pairing-relay-candidate.ts:58-59,70-71`) — worst case ~15s of + silence. (Correction: the preliminary "~3×2s of backoff" was wrong; the sleeps are small, the + director resolves dominate.) The relay E2EE layer itself has **no timers**: a pairing relay + request is unbounded except the screen's 25s cap (`app/pair-confirm.tsx:27`). +5. Pairing logs also never reach `connectionLogStore` (single producer: + `src/transport/client-context.tsx:132`), so the Connection Log screen shows nothing about a + pairing that just failed. + +Post-pairing phase: + +6. `pair-confirm` calls `closeHost(hostId)` then replaces to `/h/` + (`app/pair-confirm.tsx:118-123`). +7. The destination re-acquires a client asynchronously (grey `'disconnected'` default during the + Keychain read, `src/transport/client-context.tsx:221`), then dials the **LAN endpoint first** + (`src/transport/host-logical-client.ts:12`) — amber for up to `CONNECT_TIMEOUT_MS = 12s` + (`src/transport/rpc-client.ts:126`) on a black-holed LAN. +8. Relay recovery cannot start earlier: `needsRecovery` treats `connecting`/`handshaking` as live + progress (`src/transport/mobile-relay-reconnect-controller.ts:73-75`), checked at supervisor + start and on every retry (`src/transport/mobile-endpoint-supervisor.ts:106,146`). +9. When the direct dial finally fails, the relay dial runs invisibly (same `migrateTo` mechanism + as S2) → green. Worst case with a director resolution failure and grace-credential retry: + ~29–58s under the old session's labels. +10. The "Orca Relay" path label only renders once `state === 'connected'` + (`src/components/MobileHostCard.tsx:23,47`) — the user learns the phone is using relay only + after the wait ends, and `classifyConnection` has no relay-aware branch + (`src/transport/connection-health.ts:45-100`). + +## 3. Anti-pattern sweep + +### (a) Uncoordinated deep pushes into `/h` from outside the host stack + +Coordinated today (mount-then-replace): host edit (`src/transport/host-edit-navigation.ts`) and +Tasks (`src/tasks/mobile-task-navigation.ts`). Note host-edit's predicate is weaker — it checks the +root route only and can fire its `replace` while the nested stack is still gated/unmounted; Tasks +proves the nested stack exists (`mountedHostStack`, `mobile-task-navigation.ts:53-70`). + +Bare pushes remaining (host stack plausibly cold at each): + +| Call site | Target | Cold scenario | +|---|---|---| +| `app/_layout.tsx:127` via `src/notifications/notification-routing.ts:58,64` | `/h//session/` or `/h/` | **Coldest path** — `getLastNotificationResponse()` after launch from a killed app, plus the warm listener | +| `app/index.tsx:740-746` (Resume) | `/h/[hostId]/session/[worktreeId]` | Fixed by PR #12001 | +| `app/index.tsx:835` (Account-usage card) | `/h//accounts` | Home is the root route | +| `orca://` deep links (scheme in `app.json:9`, no linking config) | any `/h/...` | Default filesystem linking, zero coordination; `app/_layout.tsx:52-58` only intercepts pairing codes | +| `app/h/[hostId]/history/[worktreeId].tsx:15`, `pr/[worktreeId].tsx:16` | redirect to source-control | A cold deep link to these hits the same cold-navigator resolution first | + +Shallow index-only pushes (`app/index.tsx:723,803`, onboarding/pair flows) don't need coordination. +No ``, `navigationRef`, or `router.navigate` anywhere in `mobile/`. + +Related hazard: `HostProtocolGate` **unmounts the mounted HostStack mid-connect** for a first-visit +host — stack mounts while `connecting`, is replaced by a spinner when `status.get` goes in flight +(`statusPending` true only when connected: `src/transport/host-status-gates.ts:111`), then remounts +(`src/components/HostProtocolGate.tsx:34-44`). A deep navigation that resolved into the first mount +can be destroyed by the gate cycle. + +### (b) Surfaces that render grey 'disconnected' during expected transients + +Store defaults: every read API on the canonical store defaults to `'disconnected'` for a missing +entry — `getState` (`src/transport/client-context.tsx:221`), `useHostClient` seed/re-seed/unbound +fallback (`:343-345,377,393`). Exactly one call site defaults to amber instead: the home screen's +`hostStates[id] ?? 'connecting'` (`app/index.tsx:707,903`), whose reconciliation effect also +refuses to write `'disconnected'` for a never-tracked host (`:378-394`) — home already solved +locally what every other surface gets wrong. + +The grey window is not one frame: `openEntry` awaits `loadHosts()` (a Keychain/SecureStore pass) +**before** inserting the store entry (`client-context.tsx:87-161`, insert at `:153`), so a cold +start or deep link into `/h/[hostId]` shows grey for the whole Keychain latency. The physical +client is not the cause — it already reports `'connecting'` synchronously by the time `connect()` +returns (`rpc-client.ts:302,967`). Additionally, `forceReconnect` deletes the entry then awaits the +async reopen (`client-context.tsx:201-218`), so **every Retry button drives the UI grey before +amber**. + +Surfaces that show grey / "disconnected" copy for a healthy host during these transients (all via +`useHostClient`): host header dot (`app/h/[hostId]/index.tsx:819`); host toolbar + FAB disabled +(`:850-860,941-1000,1063-1078,1209`); the workspace list body renders **nothing at all** for +`disconnected` — `selectHostWorkspaceListState` falls through to `null`, not even a spinner +(`src/worktree/host-workspace-list-state.ts:17-24`); tasks header dot + "Connect to a host" empty +state (`app/h/[hostId]/tasks.tsx:8681,8661-8663`); session dot (no `verdict` prop at all, +`session/[worktreeId].tsx:4434`) and the literal "Disconnected" chip (`:4246-4255`); native-chat +composer lock (`src/session/MobileNativeChatView.tsx:427-432`); source-control / git-history / +diff-review / file-explorer / agent-history "Waiting for desktop…" states; the connection-log +screen prints the raw enum (`app/connection-log.tsx:113-117`); home's Resume/Accounts/Tasks/Quick +Action gates all read `=== 'connected'`; voice settings goes fully inert +(`app/voice-settings.tsx:50-55`). Counter-examples that behave well: home host card, the accounts +screen ("Connecting to {host}…" + cached snapshot, `app/h/[hostId]/accounts.tsx:366-370`). + +Deliberate transients that publish `'disconnected'` while healthy work proceeds: relay suspend on +focus/network nudges (S2); background suspend (`src/transport/mobile-endpoint-supervisor.ts:123` — +correct per billing, but state stays grey through the entire foreground re-dial rather than +flipping to `'connecting'`); post-migration cleanup (`:251-253`); `closeHost` during the +pair-confirm handoff (`src/transport/client-context.tsx:83`); three open-failure paths +(`:107,114,135`). + +Destructive companion pattern — state flips don't just recolor, they **wipe loaded data**: +`host-status-gates.ts:32,100-112` wipes cached host capabilities on every disconnect; +`tasks.tsx:2774-2800` resets the whole screen's hydration and force-closes ~15 sheets; +`session/[worktreeId].tsx:2043,2432-2439,3713-3716` clears diff comments/capability flags/agent +lists; the PR sidebar hides entirely (`src/session/use-mobile-pr-branch-context.ts:59-66` → +`use-mobile-pr-sidebar-controller.ts:113-118`); git history blanks rows on the **reconnect** branch +(`src/source-control/MobileGitHistoryList.tsx:63-68`); the repo cache survives disconnect but is +wiped by the rejected in-flight call (`NewWorktreeModal.tsx:330-333`); the worktree cache is read +only at mount/hostId change (`app/h/[hostId]/index.tsx:129,330`), never on reconnect, so a >30s +entry means an empty remount. + +Same bug class in a second enum: `workspaceSshStatusLabel` defaults a `null` SSH status to +"Disconnected" (`src/tasks/workspace-ssh-gate.ts:14-37`, rendered in `NewWorktreeModal.tsx:863` +and `tasks.tsx:10970`). + +### (c) Invisible relay establishment phases + +- `connectMobileRelayRpcSession` (normal relay connects) has **no onLog** — the entire relay + session lifecycle emits nothing (`src/transport/mobile-relay-rpc-session.ts:30-39`); the + supervisor logs only coarse post-hoc lines (`mobile-endpoint-supervisor.ts:185-188,261`). +- `migrateTo` structurally discards the dialing session's `connecting`/`handshaking` states + (`src/transport/stable-logical-rpc-client.ts:182-223,267-299`). +- Direct→relay upgrade path has no sink at all (`src/transport/mobile-endpoint-lifecycle.ts:49-58`, + `mobile-relay-direct-upgrade-controller.ts:19`). +- Pairing relay path fully silent (S3 above); pairing logs never reach `connectionLogStore`. +- Path label ("Orca Relay") gated on `connected` (`src/components/MobileHostCard.tsx:47`); + `classifyConnection` collapses `connecting`/`handshaking`/`reconnecting` and has no relay branch. +- Regression suite for connect-label stalls exists for the direct path only + (`src/transport/cellular-connecting-label-stall.test.ts`); no relay equivalent. + +## 4.

Audit the §3(b) "wipe" sites for any that +key on `'disconnected'` specifically. +Tests: `client-context.test.ts` known-vs-unknown host defaults + forceReconnect state sequence; +host screen test for the stale-list fallback under `'connecting'`. + +### F3 (S3, quick win) — give the pairing relay path a log sink ✅ IMPLEMENTED (this branch) + +Approach: add an optional `onLog` to `connectMobileRelayForPairing`, +`createRecoveringPairingRelayCandidate`, and `resolvePairingInviteThroughDirector`; thread +`connectOptions.onLog` from the coordinator to the relay candidate; emit phase lines ("relay: +resolving director…", "relay: cell connected", "relay: E2EE handshake…", "relay: authenticated", +"relay: installing credential…"). Optionally also append pairing logs into `connectionLogStore` +under the resolved host id so the Connection Log screen has a record post-pairing. +Files: `src/transport/mobile-relay-physical-client.ts`, `pairing-relay-candidate.ts`, +`mobile-relay-invite-director.ts`, `pre-profile-pairing-coordinator.ts`. +Risk: none (additive, phone-local). Old desktops: unaffected — logging only. +Tests: coordinator test asserting relay-path log entries arrive through `connectOptions.onLog`; +extend `pairing-relay-candidate.test.ts` for per-attempt lines. + +### F4 (S1 class, quick win after F0) — coordinate the remaining bare deep pushes + +Approach: route notification taps (`app/_layout.tsx:127` + `src/notifications/notification-routing.ts`) +and the Account-usage card (`app/index.tsx:835`) through `src/navigation/host-stack-navigation.ts` +once #12001 lands; migrate host-edit onto the same stricter mechanism (#12001's own noted +follow-up). `orca://` deep links can follow later via a route-level guard. +Risk: notification cold-start ordering (push before root nav ready) — the mechanism already +tolerates that by waiting for state commits. +Tests: reuse the `host-stack-navigation.test.ts` harness for a notification-shaped target. + +### F5 (S2/S3, deeper) — make relay dials visible through `migrateTo` + +Approach: while the logical client is `suspended`/`'disconnected'`, have `migrateTo` forward the +dialing session's state publishes (`connecting`/`handshaking`) to `publishState`, unbinding on +success (normal bind takes over) or failure (restore `'disconnected'`). Guard: never downgrade a +still-`'connected'` previous session (make-before-break migrations must stay green). Follow-on UI: +show the path being dialed ("Connecting via Orca Relay…") by exposing the pending path, and let +`MobileHostCard`/`classifyConnection` render it while not yet connected. +Files: `src/transport/stable-logical-rpc-client.ts` (+ its test), `src/transport/connection-health.ts`, +`src/components/MobileHostCard.tsx`, `src/transport/mobile-connection-path-label.ts`. +Risk: state-ordering regressions in the pinned stable-client and connecting-label suites; keep the +forwarding strictly gated on suspended/disconnected. +Tests: add a relay-path analog of `cellular-connecting-label-stall.test.ts`; stable-client cases: +forwarded states during suspended dial, no forwarding during live-session replacement, failure +restores `'disconnected'`. + +### F6 (S3, deeper) — happy-eyeballs relay start post-pairing + +Approach: when a relay credential bundle exists and the direct dial has not authenticated within a +short grace (2–3s), start the relay dial in parallel instead of waiting for the 12s direct failure; +first authenticated path wins via the existing `migrateTo`/hysteresis machinery. Scope initially to +the first connect after pairing (or hosts whose last success was relay) to avoid pointless relay +sockets on healthy LANs. +Files: `src/transport/mobile-endpoint-supervisor.ts` (start/needsRecovery gating), possibly a +phone-local `HostProfile` hint field (no protocol impact; old desktops never present `relay`, so +the path is naturally guarded). +Risk: racing direct is exactly what `needsRecovery`'s design avoids — needs the mutex +(`operationInFlight`) audit and dwell/hysteresis respect; billed relay data on LANs if scoped too +broadly. +Tests: supervisor fake-timer cases: black-holed LAN converges in ~3-5s; healthy LAN never opens a +relay socket; relay loser closed after direct wins. + +### F7 (S1, deeper) — catalog-validate resume targets + not-found bounce + +Approach: (1) on Resume tap with the host connected, validate the target against the freshest +`worktree.ps` result (not the snapshot-seeded cache); if absent, open the host index instead. +(2) In the session screen, once connected and the catalog is known, bounce unknown `worktreeId`s +(exempting `folder:` and floating-workspace sentinels, `app/h/[hostId]/session/[worktreeId].tsx:852-854`) +to the host index with a notice. (3) Use the validating reader in +`src/worktree/last-visited-worktree-repo.ts` on home instead of the raw `JSON.parse` +(`app/index.tsx:315-322`), and import the storage-key constant at both literal call sites. +Risk: false bounces during slow catalog loads — only bounce on a *confirmed* fresh catalog miss. +Tests: repo tests for the validating reader on home; session-screen bounce cases incl. sentinel +exemptions. + +### F8 (S1 aggravator, cheap) — stop the Resume/Tasks layout shift + +Approach: reserve the Resume card's slot (fixed-height placeholder or render-below-Tasks) so its +late arrival cannot move the Tasks card under the thumb; alternatively render the card immediately +from the snapshot in a disabled state until the host connects. +Files: `app/index.tsx` footer. +Risk: none. +Tests: render test asserting footer order/height stability across `resumeWorktree` arrival. + +### F9 (S1 class, deeper) — HostProtocolGate should not unmount a mounted stack + +Approach: once the HostStack has mounted for a host, keep it mounted and overlay the pending +spinner instead of replacing children, preserving in-flight nested navigation; keep the hard +replace only for the `blocked` verdict. +Files: `src/components/HostProtocolGate.tsx`. +Risk: the gate exists so child routes don't call too-new RPCs while compatibility is unknown — an +overlay must still block interaction until resolved; verify child mount effects don't fire gated +RPCs pre-verdict before choosing overlay vs. current behavior. +Tests: gate test asserting no unmount across `statusPending` for an already-mounted host. + +### F10 (S2 class, deeper) — stop wiping loaded data on transient state flips + +Approach: audit the §3(b) destructive-clear sites and make each preserve data across a +not-`'connected'` blip, clearing only on host change or explicit sign-out. Top offenders by felt +impact: git history blanking rows on the reconnect branch +(`src/source-control/MobileGitHistoryList.tsx:63-68` — refetch without `setRows(null)`); the repo +cache wiped by the rejected in-flight call (`NewWorktreeModal.tsx:330-333` — keep last-good on +error); the diff-review "ready-state preserved" branch that is dead code because it sits after the +early return (`src/session/use-mobile-diff-review-controller.ts:85-89`); host capability wipe +(`src/transport/host-status-gates.ts:32`); the tasks-screen full re-hydration +(`app/h/[hostId]/tasks.tsx:2774-2800`); worktree-cache re-read on reconnect, not only at mount +(`app/h/[hostId]/index.tsx:129,330`). +Risk: showing stale data as if live — pair each preservation with the existing staleness verdicts +rather than inventing new indicators. The in-repo reference pattern is +`src/worktree/home-worktree-info.ts:27-47`: counts older than a 10min TTL render as +"Last known: N worktrees" instead of being dropped, and `markHomeWorktreeCatalogUnavailable` +preserves proven counts across a failed refresh, flagging only `staleCounts`. +Tests: per-surface "data survives disconnect→reconnect" cases; F1 largely removes the *trigger* +(suspend blips), so this is hardening, not the primary fix. + +## 5. Backward compatibility (old/new phone × old/new desktop) + +- Every fix above is phone-app-local; no RPC methods, close codes, credential formats, or pairing + steps change.

Orca orchestration proposal

-

Strong primitives. Little magic. No orchestration product inside the product.

-

- Orca should make it intuitive for a coordinating agent to start workers, communicate, - wait, observe output, and recover safely. Orca supplies dependable building blocks; - the agent decides the orchestration strategy. -

- -
- CLI and runtime only - agent-directed - multi-server capable - explicit effects - no commit tracking -
- -
- -
- The common agent loop -

- Create and bind one Run for the coordination effort; after that its ID is carried - automatically. Create tasks, start workers on this or another connected Orca - server, send messages, wait for inbox mail, and read or stop workers. Options - refine those operations without adding policy. -

-
-
- -

- The test for the design is simple: after reading a few examples, an agent should be - able to predict what every command creates, reuses, blocks on, and returns. -

-
- -
-
-

What we learned

-

The current problems are coordination problems, not missing product surfaces.

-

- The research found real reliability gaps, but the earlier proposal responded by - adding a scheduler, integration subsystem, dashboard, and large control-plane model. - Those additions would make the common agent workflow harder to understand. -

-
- -
-
-

Current

-

Lifecycle mail arrives through prompt injection

-

- Messages persist, but coordinator delivery may wait for the agent to pause. If it - keeps polling or working, messages can collect and flood the editable input after - a manual interruption. -

-
- -
-

Needed

-

A structured, blocking inbox call

-

- Typed worker lifecycle messages return from a pending tool request or the next explicit - read. Routine lifecycle delivery never writes into the coordinator's prompt. -

-
-
- -
-
-

Current

-

Starting a worker is assembled from low-level pieces

-

- Creating a worktree may already create a terminal, but an agent can miss that and - create another terminal before launching the worker. -

-
- -
-

Needed

-

One composed start operation with full topology and setup choices

-

- The operation composes existing worktree, setup, terminal, and agent creation and - returns exactly which resources it created or reused. -

-
-
- -
-
-

Current

-

Terminal scrollback is treated as agent history

-

- Full-screen TUIs can redraw or discard the useful conversation, making terminal - reads incomplete or misleading. -

-
- -
-

Implemented

-

Exact structured output with a truthful fallback

-

- Orca reuses its pane-scoped hook association to read a supported Codex, Claude, - OpenClaude, or Grok transcript. When it cannot prove that source, it returns - labeled bounded terminal output instead of guessing a session. -

-
-
- -
-
-

Current

-

Results are mostly worker assertions

-

- Orca verifies that the active dispatch reported worker_done, but the - summary, changed files, tests, and report path come from the worker. -

-
- -
-

Needed

-

Be explicit about what Orca observed

-

- Keep lifecycle authority separate from worker-reported content. Do not add commit, - test, merge, or integration tracking merely to make the report appear stronger. -

-
-
-
- -
-
-

Design rules

-

Reliability should live underneath a small interface.

-

- Strong primitives have narrow, testable contracts. They do not need to expose every - mechanism used to make the contract safe. -

-
- -
-
- 01 -

The coordinator owns strategy

-

- The agent chooses decomposition, ordering, parallelism, placement, review, and when - to wait. Orca does not schedule ready tasks automatically. -

-
-
- 02 -

Every effect is visible

-

- Responses say which connected server, worktree, setup, terminal, execution host, - and agent were created or reused. Defaults are reported, not hidden. -

-
-
- 03 -

Simple default, explicit escape hatch

-

- The common path needs few arguments and preserves worktree/setup choices. Uncommon - custom launches stay on the existing low-level commands instead of bloating start. -

-
-
- 04 -

Observation is honest

-

- Orca distinguishes observed process state from worker-reported claims and labels - the source of transcript or terminal output. -

-
-
- 05 -

Remote ambiguity stays ambiguous

-

- A disconnect after a remote mutation returns outcome_unknown. Orca - does not silently repeat a command that may have succeeded. -

-
-
- 06 -

Safety is not orchestration policy

-

- Stable identity, stale-worker fencing, and owner routing prevent corruption. They - do not choose what work should happen next. -

-
-
- -

- A feature belongs in the core only if it makes an existing primitive safer or clearer. - Tracking extra domain facts—commits, merges, budgets, priorities, or organizational - roles—is not automatically a stronger primitive. -

-
- -
-
-

Primitive 1 · Scope and identity

-

Four public concepts, each with one job.

- A Run prevents unrelated coordination efforts from mixing. Tasks describe work, - Dispatches authorize workers, and Messages communicate. Existing worktree and - terminal resources remain independently usable. -

-
- -
-
-

Run

-

A lightweight namespace and stable coordinator mailbox. It never schedules work.

-
-
-

Task

-

A durable description, status, and optional dependencies. Creating it starts nothing.

-
-
-

Dispatch

-

One supervised worker assignment and its current lifecycle authority.

-
-
-

Message

-

Durable communication or a typed lifecycle report returned through the inbox.

-
-
- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Persisted worker stateTask state and allowed next action
starting / readyTask is dispatched; only show, read, message, or stop may act on it.
start_unknownTask is blocked; recover the same request receipt, inspect, stop, or abandon.
failed - Confirmed start failure and authenticated worker failure both leave Task - failed. Either permits an explicit --retry-of replacement. -
succeededTask is completed; create a follow-up Task rather than retrying it.
stopping / stop_unknown - Task is blocked and lifecycle authority is fenced; inspect termination or - explicitly abandon before replacement. -
stopped / abandonedTask is blocked and permits an explicit --retry-of replacement.
-
- -
- - - - - - - - - - - - - - - - - - - - - -
Run operationExact effect
run-create - Creates a run and stable coordinator mailbox on the coordinator's selected - Orca server—its Run home—then binds the current coordinator terminal as its - active consumer. -
run-use --id run_123 - Explicitly binds or rebinds the current terminal to that run. Rebinding fences - the prior consumer generation and cancels its waiter. A terminal has at most - one active run binding. -
run-current / run-list / run-showReports bindings and state without changing tasks, workers, or mail.
-
- -
-
-

Run IDs stay out of the common path

-

- A command resolves the run only from explicit --run or the current - terminal binding—never from a worktree or an “exactly one candidate” guess. - Commands return the resolved Run or runId where it is needed for later - control; agents do not carry a separate resolution-mode field. -

-
-
-

Low-level commands remain run-free

-

- Ordinary worktree, terminal, and full-handoff commands do not create or require a - Run. Runs exist only for supervised coordination that needs durable grouping. -

-
-
-

One home, workers anywhere

-

- A Run has one home server that owns its tasks and inbox. A Dispatch may point to a - worker on any connected Orca server; Orca relays that worker's messages back to the - home automatically. -

-
-
- -

- ELI5: a Run is a folder label plus a return address. It keeps one coordination - effort's tasks and mail together and gives workers on your Mac or Windows server the - same stable place to reply. - Create or select it once, then ordinary orchestration commands inherit it. It does - not create resources, choose workers, schedule tasks, or group projects. -

- -

- If a supervised command has neither --run nor a terminal binding, return - run_required with exact run-create and run-use - examples. Never silently create or infer a Run. -

- -

- V1 does not archive or delete Runs. run-list and run-show keep - old coordination state inspectable; retention administration waits for a demonstrated - clutter or storage problem instead of complicating the common lifecycle now. -

- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Canonical commandCompatibility decision
run-create/list/show/use/currentNew lightweight scope commands. They never decompose or schedule tasks.
task-create/list/updateKeep the current flat command names and add Run association.
dispatchKeep as the low-level binding to an exact existing terminal.
worker-start/show/read/stop/abandonNew composed supervised-worker operations.
send/ask/reply/checkKeep and strengthen the current message operations.
Current scheduler-like orchestration run --spec - Must be removed or renamed in Phase 0 before run-* can ship. It is - not an alias for a lightweight Run and is not part of this scheduler-free - design. -
-
- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
IDWho normally carries it
runIdThe terminal binding carries it; agents pass it only to override context.
taskIdThe coordinator uses it for dependencies and worker start.
dispatchId - Receipts and worker preambles carry it; show, read, stop, abandon, retry, and - lifecycle reports use it. -
deliveryIdThe current mailbox consumer carries only its last unacknowledged delivery.
messageId / threadId - reply takes a message ID and infers its thread. Agents do not - manage a separate question identifier. -
Resource IDsReceipt data until an agent explicitly reads, stops, or reuses that resource.
RPC request ID - The client transport creates it automatically. Agents only echo the returned - retry token after an unknown outcome; they never invent one. -

Primitive 2 · Supervised worker start

-

One request, predictable behavior for every topology.

-

- worker-start is one synchronous composition of existing worktree, setup, - terminal, and dispatch operations. It is not a background executor, external - transaction, or placement engine. The coordinator chooses the topology; Orca returns - only after the composition is ready, failed, or honestly unknown. -

-
- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
TopologyDefault terminal behaviorSetup behavior
Current worktree - Create one fresh agent terminal. Never reuse the coordinator terminal or an - arbitrary idle terminal. Reuse requires explicit --terminal. - not_applicable; do not rerun setup or configured tabs.
Named existing worktreeCreate one fresh agent terminal; reuse only an explicitly selected terminal.not_applicable; creation-time setup is not replayed.
New child worktree - Use agent-first worktree creation and reuse its returned agent terminal. Never - create a second shell/agent terminal. - - Default to run. Setup and agent launch start side by side unless the - repository explicitly uses wait-for-setup. skip or - inherit must be explicit. -
New top-level worktreeSame agent-first behavior, with top-level Orca lineage. - Same setup default: run a configured hook; use an explicit escape hatch only - for a concrete reason. -
-
- -
-
-

Worktree option parity means pass-through

-

- The exact repository selector, name, base branch, child/top-level lineage, setup, - and display/comment metadata are validated and passed to the existing worktree - primitive. --on already chooses the connected Orca server, so V1 does - not add a second project/host placement vocabulary to worker-start; - agents may use low-level worktree create when that convenience selector - is important. -

-

- Folder projects have no distinct Git worktree to create. New-child and - new-top-level therefore fail before effects; use current or an exact existing - folder workspace. -

-
-
-

Choose a connected server only when needed

-

- The default is the Run home. Use --on windows (a saved Orca environment - name or ID) only to place a worker on another connected server. V1 resource IDs - are server-scoped, so every remote existing worktree or terminal also requires - --on. Orca never guesses an owner from a same-looking ID and echoes the - resolved server name in the receipt. -

-
-
-

Agent selection is honest

-

- When creating a terminal, V1 requires an explicit --agent that resolves - through Orca's configured launcher before any effect. Composed start does not - promise custom model, environment, or arbitrary command arguments that agent-first - worktree creation cannot actually pass through. -

-
-
-

Setup is the safe default

-

- For every new worktree, omitted --setup resolves to - run. If a setup hook exists, Orca launches it; if none exists, the - receipt says not_configured. Preserve the repository's existing - setupAgentStartupPolicy: its default is start-immediately, - so setup does not delay agent launch or task delivery. Only an explicit - wait-for-setup policy gates the agent. An agent may choose - skip or inherit only for a specific reason it states in its - work log. Orca trusts that judgment and adds no approval gate. -

-
-
-

Supervised means lifecycle injection

-

- Task and dispatch input is delivered only after agent readiness. Ordinary - worktree/terminal commands remain the full-handoff path without lifecycle duties. -

-
-
- -

- worker-start --on windows is deliberately different from Orca's existing - global --environment windows. --on keeps the command and Task on - the bound Run home while selecting only the worker server. The global flag still means - “send this whole CLI command to that environment” and must not silently change meaning. -

- -

- Validate conflicts before effects: --terminal requires a current or named - existing worktree and cannot combine with --agent, setup, or new-worktree - creation options. New worktrees require a name and accept only options supported by - the selected underlying worktree command. Custom agent argv stays on the explicit - low-level worktree create → terminal create --command → - dispatch path, but that two-step path is legal only with - start-immediately; it cannot preserve an explicit - wait-for-setup policy because the later terminal is not the creation-time - startup. Use an agent-first configured launcher or stop and ask rather than bypassing - that policy. current always means the coordinator's current - worktree on the Run home and cannot combine with remote --on. A remote - existing worker needs an exact worktree/terminal selector or an explicit server so - same-looking resources are never guessed. Every resolved default includes its source. - Discover a remote selector with an explicit read-only command such as - orca --environment windows worktree list --json, then copy the returned - opaque worktree ID into worker-start --on windows. -

- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Placement/federation errorMeaning
server_requiredThe selected runtime cannot provide connected-server orchestration.
worktree_not_found_on_serverThe exact worktree does not exist on the selected worker server.
terminal_worktree_mismatchThe exact terminal is not owned by the selected worktree.
resource_server_mismatch - A worker-server receipt names a different Dispatch or authenticated Run home; - Orca never adopts that attachment. -
agent_unconfiguredThe requested launcher is unavailable; no worktree or terminal was created.
-
- -
- - - - - - - - - - - - - - - - - - - - - -
Task acceptanceWorker-start effect
First start - Requires a ready Task with no current Dispatch. The runtime creates the - Dispatch and moves the Task to dispatched in one local transaction before - running the composed effects. -
Replacement attempt - Requires --retry-of naming the Task's current failed, stopped, or - abandoned Dispatch while the Task is failed or blocked. Start creates the next - Dispatch generation and moves the Task back to dispatched atomically; the agent - never performs a preparatory task-update. -
Anything else - Return task_not_startable naming the rejected Task/Dispatch and - perform no worker effects. Completed work gets a new follow-up Task; an unknown - or nonterminal Dispatch must first be inspected, stopped, or abandoned. -
-
- -

- ready has one testable meaning: the selected agent terminal reached - tui-idle, the local or remote Dispatch attachment is durable, and the - lifecycle preamble plus task input was accepted. Under the default - start-immediately policy, setup may still be running and its exact state is - returned in the receipt; its outcome never gates readiness, even if failure is observed - before the agent reaches tui-idle. Under an explicit - wait-for-setup repository policy, setup must complete successfully before - agent launch and task injection. Agent-first worktree creation launches without the - task prompt so Orca can establish authority before injection. The effective timeout - and startup policy are echoed in every receipt. - A successful gated receipt reports setup succeeded. A confirmed setup - spawn/script failure reports failed before task input, while a timeout may - honestly retain running rather than inventing a failure. -

- -

- Underneath the call, one transaction creates a starting Dispatch, moves the - Task, and records the retry request before effects. Orca journals each irreversible - stage and resource receipt before advancing. Restart recovery can therefore prove - no-effect, return a durable remote result, or remain honestly - outcome_unknown. A pending accepted start retains its Dispatch ID, so - repeating the exact request after restart returns that ID and its - worker-show command instead of inviting a second start. Orca does not - resume unfinished orchestration stages in the background; a setup process - intentionally launched under - start-immediately may continue exactly as its receipt states. -

- -

- With start-immediately, the start receipt carries the latest observed setup - state. Only a setup state change after that receipt updates worker-show and - emits a typed notice; setup never rewrites Dispatch readiness or decides whether the - worker should stop. With explicit wait-for-setup, setup failure is a start - failure before task input is sent. -

-
- -

- Receipts enumerate every created or reused terminal with a role—agent, setup, or each - configured terminal (including each tab/split pane), with exact tab and leaf identity - when available. Setup may be reported running only after its exact - PTY spawn receipt is durable. These role-tagged effects are also the authoritative - residual-resource list used by restart inspection and failure recovery. -

- -
- - - - - - - - - - - - - - - - - - - - - -
Start stateMeaning and next action
ready - Agent is ready and lifecycle input was accepted. The return receipt contains - every created or reused effect; no separate startup notice is required. -
failed - Return the failed stage, last error, residual resources, Task/Dispatch state, - and the durable mutation receipt. The composition itself has returned, but any - surviving setup, terminal, or agent process is listed honestly as a residual - resource; Orca never implies that failure cleaned it up. The coordinator - chooses the matching recovery branch below. -
outcome_unknown - The connection failed after an effect may have happened. Return the operation - stage, mutation.requestId, durable effects/residuals, and exact - worker-show/worker-abandon commands. A replacement is - rejected until inspection proves it safe or the coordinator explicitly - abandons the old Dispatch. -
-
- -
- - - - - - - - - - - - - - - - - - - - - - - - - -
Unknown-start recoveryExact contract
Query and reconcile - worker-show --dispatch dispatch_7 routes from the Run home to the - owning worker server and execution host. If its durable receipt proves the - original worker became ready, failed, or stopped, the home reconciles that same - Dispatch; no separate adopt operation exists. -
Safe retry - --retry-of dispatch_7 links a new attempt but does not silently - reuse prior placement. The coordinator repeats an explicit valid topology and - agent/terminal choice, which may deliberately differ from the old attempt. A - new Dispatch is allowed only after the prior one is failed, stopped, abandoned, - or reconciled as no-effect. While it remains unknown, return - task_not_startable without mutation. -
Explicit stop - worker-stop --dispatch dispatch_7 may fence a - ready or start_unknown Dispatch. The owning server - closes a terminal only when its durable attachment still matches the exact - pane and process incarnation. Unattached, missing, exited, or identity-changed - workers become stop_unknown with no process action. If the remote - server durably stopped the exact worker but its response was lost, a later - worker-show reconciles that authoritative stopped receipt. -
Explicit abandon - worker-abandon --dispatch dispatch_7 fences future lifecycle - mutations from that Dispatch and records every possibly-live resource. It sends - no remote command, claims no process stopped, deletes nothing, and warns that a - concurrent worker may remain. The coordinator may then start a replacement. - Abandoning an older superseded Dispatch is a no-op and cannot block or rewrite - the replacement Task. -
-
- -

- The Dispatch ID is the worker identity. Do not add another agent-facing start ID. - Every mutating CLI result includes one opaque mutation.requestId for - recovering that exact request after a lost response; agents never invent it. A - transport failure exposes the same value as orchestrationRequestId in its - error recovery data. Semantic retry - explicitly names the prior Dispatch ID and never replays an unknown effect. After a - remote start, show, read, stop, abandon, and message routing use the Dispatch receipt; - the agent does not repeat --on for those controls or carry server IDs. A - replacement worker-start is a new placement decision and names its target - again. -

- -

- Transport retry and semantic retry are different. If the response itself was lost, - reissue the identical mutation with --retry-request req_7 to recover its - durable receipt; a changed canonical payload returns request_mismatch. Once - that receipt says outcome_unknown, inspect by Dispatch ID instead of - replaying it repeatedly. --retry-of dispatch_7 creates a new worker attempt - only after the old attempt is safe to replace. -

Primitives 3 and 4 · Message and wait

-

Structured mail is inbox-only, durable, and explicitly consumed.

-

- The inbox is an agent API, not product UI and not terminal input. It strengthens - Orca's existing message store and check --wait; it does not add an Event - subsystem or a second orchestration engine. -

-
- -

- send, ask, reply, completion, heartbeat, and runtime - notices only persist structured state and wake a pending tool waiter. Only explicit - dispatch --inject and terminal send may modify terminal input. - From an active Dispatch, lifecycle send and ask default to that - Dispatch's owning Run mailbox. “Sent” means durably accepted—not pasted, observed, or - acted upon. -

- -
-
-

run:run_123

-

The stable coordinator mailbox stored with that Run in the Orca runtime.

-
-
-

dispatch:dispatch_7

-

The exact supervised worker generation, independent of terminal handle changes.

-
-
- -

- V1 deliberately has no task: message recipient. Use the Run for guidance - that survives reassignment and the exact Dispatch for attempt-specific control. This - avoids a hidden acceptance-time retargeting rule. -

- -

- Orca authenticates lifecycle reports automatically. The worker supplies only the Task - and Dispatch IDs injected in its preamble; it never supplies Run, runtime, host, - terminal, capability, or attestation IDs. At injection, Orca gives the managed pane a - narrow unforgeable Dispatch capability through its CLI bridge. The worker server - verifies that capability and its local pane; the Run home accepts the relayed report - only from the pinned paired peer for that Dispatch. Stop, abandon, or replacement - revokes it. Other reports remain stale history and cannot change Task state. This is - lifecycle integrity, not a general permission system. -

- -

- A federated worker omits --to and --run; its authenticated - Dispatch already identifies the only valid Run home. Explicit targets are rejected - instead of being silently ignored or redirected. -

- -
-
-

One Run home

-

- The coordinator's server stores the authoritative Run, tasks, inbox ordering, and - acknowledgments. Worker servers do not replicate the Run database or elect a new - home. -

-
-
-

Remote mail waits safely

-

- A worker server durably retains messages for its remote Dispatch until the Run - home imports and acknowledges them. Replies wait at the home until the worker - server reconnects. This is a narrow relay queue, not a replicated global inbox. -

Inbox ruleV1 contract
Ordering and sizeFIFO by mailbox sequence, bounded to 50 messages per delivery.
Outstanding batch - One per mailbox. Until acknowledged, return the same Delivery ID and batch; - newer mail waits behind it. -
Acknowledgment - Whole-batch and idempotent. Repeating an acknowledged Delivery ID returns the - recorded result and does not consume newer mail. A Delivery is bound to the - consumer generation that received it; a fenced coordinator gets - consumer_fenced and cannot consume the replacement's mail. The same - current-consumer check applies to coordinator replies and other mailbox - mutations. -
Waiters - One active actionable waiter per mailbox. A second returns - waiter_exists; it never races to consume the batch. -
Crash safety - Receiving a batch never marks it consumed. Unacknowledged mail survives client, - mailbox-consumer, and runtime restart. -
Atomic continuation - check --ack delivery_81 --wait commits ack, checks queued mail, - then registers the waiter as one runtime operation. -
-
- -
-
-

History modes do not consume

-

- check --peek, --all, and type-filtered history reads are - read-only debugging surfaces. Legacy consume-on-check behavior is deprecated. - Rename local formatting flag check --inject so it cannot imply delivery. -

-
-
-

Timeouts are typed checkpoints

-

- Wait returns timedOut, cancelled, or - connectionLost distinctly. None means worker failure, none consumes - mail, and transport keepalive output is not a worker heartbeat. -

-
-
- -

- Actionable check, acknowledgment, and wait never create separate filtered - deliveries. A type filter may decide when a waiter wakes, but the returned Delivery is - always the oldest full FIFO batch, including earlier nonmatching mail. History modes - may filter freely because they do not consume. -

Lifecycle inputAtomic state effect at message acceptance
Authenticated active Dispatch reports worker_done outcome=succeededSet Dispatch settled/succeeded and Task completed.
Authenticated active Dispatch reports worker_done outcome=failedSet Dispatch settled/failed and Task failed. Coordinator chooses recovery.
Stale or foreign Dispatch reportPersist as stale history; do not change current Task or Dispatch state.
Malformed lifecycle reportReject the transition and return the missing or invalid field.
worker-start returns failedSet Dispatch and Task failed with an explicit recovery reason.
Confirmed worker-stopSet Dispatch stopped and Task blocked; never claim task completion.
worker-stop accepted, termination unknown - Fence lifecycle authority, set Dispatch stop_unknown and Task - blocked, and retain the process/terminal in residualResources as - possibly live. A new start remains unsafe until inspection confirms termination - or the coordinator explicitly abandons with the concurrent-worker warning. -
Confirmed worker-abandon - Set Dispatch abandoned and Task blocked, fence its later reports, and retain - possibly-live resource IDs; never claim process termination. -
-
- -

- Inbox acknowledgment confirms recipient consumption only. Lifecycle reconciliation - happens once, atomically, when the Run home imports an authenticated message. Every - terminal Dispatch transition is a home-side transactional compare-and-set: the first - committed completion, stop fence, or abandon wins; later conflicting input is retained - only as stale history. -

- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Question stateAsk/reply behavior
pending - ask from an active Dispatch defaults to its owning Run mailbox. The - first reply from the current authenticated Run consumer generation records the - answer at the Run home, relays it to the exact worker server, and wakes the - local asking call. -
answered - The pending ask or an explicit resume by the original Dispatch - returns the recorded answer. Repeating the same reply is harmless; a later - different answer conflicts. -
Wait timed out or client disconnected - Return the original question message ID and an exact - ask --resume msg_question_7 command without closing or duplicating - the question. Resume is allowed only for the original Dispatch. There is no - separate Question ID or durable expiry/deadline state machine. -
Acceptance response was lost - Retry the identical ask with its returned transport retry receipt - to recover the original message ID. A changed question conflicts; a blind new - ask is never the recovery path. -
Dispatch stopped or abandoned - The Run home atomically closes its pending questions, wakes local or resumed - waits with dispatch_inactive, and rejects later replies. -
-
- -

- Question threads are message primitives, not task gates. Use message type - question; its target-side delivery follows normal inbox acknowledgment, - while the answer lives only on durable thread state. Keep separately managed task - gates outside this proposal. -

- -
- 
# Worker: target defaults to the owning Run mailbox.
-orca orchestration ask --question "Should I preserve the legacy format?" --json
-# → question message msg_question_7
-# After a disconnect/timeout: orca orchestration ask --resume msg_question_7 --json
- 
# Coordinator: reply to the returned message ID.
-orca orchestration reply --id msg_question_7 --body "Yes; preserve it." --json
-
- -

- Blocking is a coordinator decision. The runtime must make waiting race-free, but it - must not decide that the agent has exhausted all parallelizable work. -

-
- -
-
-

Worker observation

-

Read a supervised worker by Dispatch, regardless of server.

-

- worker-read --dispatch resolves the worker server and exact process from - the Dispatch receipt. Its default auto source returns the exact - hook-reported Codex, Claude, OpenClaude, or Grok transcript when Orca can prove that - association; - otherwise it returns bounded, explicitly labeled terminal output. Agents never - choose a server, provider session ID, or transcript path, and task authority never - comes from transcript prose. -

-
- -
-
-

Default path

-

Automatic exact selection

-

- --source auto uses a proven supported transcript and falls back to - the existing bounded terminal reader with a typed reason such as - session_not_reported or - remote_capability_unavailable. -

-
-
-

Explicit policy

-

Transcript or terminal

-

- --source transcript requires exact structured output and returns a - typed error rather than falling back. --source terminal always uses - the retained terminal snapshot. -

Source-pinned continuation

-

- The returned cursor pins the Dispatch, process, source kind, and opaque source - identity. auto selects only on the first page. If the process or - provider session changes, Orca returns - worker_identity_changed or source_changed. -

-
-
-

Narrow provider readers

-

- Structured reading reuses the existing bounded native transcript decoders only - for exact Codex, Claude, OpenClaude, and Grok associations. Other providers and - mixed-version peers retain terminal fallback; no resume, live-stream control, or - universal transcript framework is added. -

-
-
- -

- Every response labels source, sourceIdentity, - cursor, status, fallback reason, and bounded warnings. Terminal fallback - preserves the existing terminal fields and accepts legacy numeric cursors; new cursors - are opaque and never expose a transcript path. The worker-owning server performs the - read, and neither local nor federated selection may guess “latest session in this - directory.” -

Hidden guarantees for one Run home and many worker servers.

-

- A coordinator on one Orca server must be able to supervise workers on another—for - example, a Run on a Mac with Dispatches on both that Mac and a connected Windows - server. The minimum federation contract routes commands and durably relays messages; - it does not replicate the Run or add scheduling policy. -

-
- -

- Agent rule: choose a remote worker once with --on. After that, keep the - Dispatch ID and follow the returned inspection commands. Reuse - mutation.requestId only to recover the same request after a lost response. - Peer identity, sequencing, capabilities, and relay acknowledgments below are Orca - implementation details—not fields agents choose or copy. -

- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Internal factV1 contractWhat agents see
Run home - The server where run-create executes owns the only authoritative - Run database: tasks, Dispatch state, inbox order, dedupe receipts, and consumer - generation. - The terminal binding routes ordinary commands home; no Run-home ID is typed.
Connected environment - The Run home stores its existing saved environment ID/name and authenticated - pairing for each worker server. Each Dispatch pins the authenticated peer - fingerprint captured at attachment, so re-pairing the saved environment to a - different server cannot retarget existing work. That relationship survives the - same remote server process restarting; the observed runtimeId - remains only an epoch. - --on windows when placement is explicit; receipts echo the name.
Remote Dispatch attachment - Before prompt injection, the worker server persists a verifier for the opaque - Dispatch capability, pinned Run-home peer identity, stable local pane and - process incarnation, effect receipts, and relay cursors. Credential material - is stored through current-user protected storage, not plaintext in a general - Run row. The worker server does not receive a copy of the Run DAG. - Nothing extra; the worker receives only Task and Dispatch IDs.
Caller pane - Each server's native, WSL, or SSH CLI bridge attaches the minted Dispatch - capability outside user parameters. The worker server verifies capability, - pane, and process incarnation; the Run home verifies the pinned authenticated - peer and Dispatch on relay import. - Orca authenticates lifecycle reports automatically.
-
- -
-
-

Home-bound coordination

-

- run-use/current, Task changes, check/ack, and replies go to the Run - home. Workers never choose or mutate the home, and there is no automatic home - failover. -

-
-
-

Server-owned resources

-

- The selected worker server owns its worktree, terminal, process, and any nested - native/WSL/SSH/relay host. The Run home stores opaque receipts and routes show, - read, stop, and retry back to that owner. -

-
-
-

Durable relay, not replication

-

- Worker-to-home lifecycle mail and home-to-worker replies remain queued at their - source until the destination imports and acknowledges them. Each item has a stable - ID, so reconnects are at-least-once on the wire and once in each inbox. -

-
-
-

Home-initiated connection

-

- The Run home uses the same saved, authenticated environment connection already - used for remote RPC. It subscribes or pulls by cursor; the Windows server does not - need a separate pairing back to the Mac or a publicly reachable callback. -

-
-
-

Dispatch generations

-

- Replacing a worker creates a new Dispatch ID; that ID is the generation. A report - from an older Dispatch or different pane remains history and cannot change current - Task state. There is no second agent-visible generation number. -

-
-
-

Idempotent control operations

-

- Before effects, both home and worker server durably record authenticated peer, - request ID, canonical payload hash, operation state, and receipt. Identical - concurrent or later attempts join or return that record; a changed payload returns - request_mismatch. Receipts expose the opaque retry ID needed after an - unknown outcome. -

-
-
-

Typed unknown outcome

-

- If a remote effect may have happened but Orca cannot prove it, return one - outcome_unknown shape with stage, mutation request ID, durable - effects/residuals, and exact inspection commands. -

-
-
-

Stop and replace

-

- Stop first commits one home-side compare-and-set that fences new lifecycle changes, - blocks the Task, and closes pending questions, then best-effort stops only the - supervised agent process/terminal. If completion already won, stop returns - already_settled; if stop won, later completion is stale history. Orca - never deletes the worktree, setup output, or unrelated configured tabs. -

-
-
- -

- The durable request receipt applies to every mutating control-plane call—Run and Task - creation, send, ask, reply, acknowledgment, start, stop, and abandon—not only remote - worker start. Read-only show, list, and output paging do not need mutation dedupe. -

- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Federated relay ruleExact contract
Worker send acceptance - Success means the worker server durably stored the authenticated message in - that Dispatch's outbound relay. The worker may finish even while the Run home - is offline. -
Home import and lifecycle - The Run home stores the message and applies any valid lifecycle transition in - one transaction before acknowledging it to the worker server. Until import, - the authoritative Task honestly remains dispatched. -
Replies and control mail - The Run home durably queues them for the exact remote Dispatch; the worker - server stores them before acknowledging the home and waking a local waiter. -
Ordering and duplicates - Each direction uses a scoped key of pinned peer, Dispatch ID, direction, and a - monotonic source sequence, plus a 128-bit-or-stronger message ID. A receiver - imports only the next contiguous sequence, buffers gaps, and acknowledges only - the highest contiguous commit. The home assigns normal inbox order at import, - without pretending simultaneous servers have a global clock. -
Bounded storage - Enforce per-message byte limits and per-Dispatch pending item/byte quotas, - coalesce heartbeats, and reserve space for one terminal lifecycle report. A - full relay returns relay_quota_exceeded; V1 adds no dead-letter or - retention workflow. -
-
- -
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Remote edgeV1 behavior
Worker server unavailable before send - Return remote_runtime_unavailable before creating a Dispatch or any - remote effect. No remote Dispatch attachment exists, so the caller may retry - normally after reconnecting. -
Connection lost after send - Return outcome_unknown, mutation.requestId, last durable - stage, and exact inspection commands. Repeating the request ID returns the - worker server's original receipt or accepts it once; it never duplicates an - effect. -
Run-home restart - Run state, dedupe receipts, and unacknowledged mail survive. The process runtime - ID is only an epoch. Reconnect resumes relay cursors for every active remote - Dispatch; if the coordinator pane cannot be safely reminted, - run-use explicitly rebinds it. -
Saved environment re-paired or removed - If its authenticated peer fingerprint differs from the Dispatch attachment, - return peer_changed with no effect; never adopt the replacement - server. Removing an environment with a nonterminal Dispatch retains a routing - tombstone for inspection and abandon rather than erasing ownership evidence. -
Servers disconnected after start - The worker may continue. Its server retains lifecycle mail and questions while - replies remain queued at the home. Silence is not failure, no worker is - automatically replaced, and other servers continue delivering normally. -
Worker-server restart - Remote Dispatch attachments, effect receipts, and unacknowledged relay items - survive. The process runtime ID may change; the Run home routes by its saved - environment relationship and pinned peer. worker-show reports - running only when the stable pane and process incarnation match; it never - adopts a same-looking pane or newly launched process. -
Mixed server versions - Before effects, both servers must advertise one aggregate - orchestrationFederationV1 contract. Missing support returns - capability_unsupported; - it never silently degrades to prompt injection, terminal scraping, or - consume-on-read mail. The worker-side mutation revalidates the pinned peer and - advertised protocol recorded for the operation, closing the probe-to-effect - race. -
Structured worker output - The worker-owning server reads an exact hook-reported Codex, Claude, - OpenClaude, or Grok transcript when supported. If the additive federated read - method is absent, auto returns bounded terminal output labeled with - remote_capability_unavailable; - transcript returns transcript_required. -
-
- -

- Capability checks cover only the new federation contracts, not every platform or host - feature. Existing worktree, setup, terminal, Git, WSL, SSH, and relay primitives keep - their proven compatibility behavior; optional, truthfully labeled observation may - degrade. -

- -

- In this proposal, “durable” means committed state survives a client or Orca process - crash and ordinary restart. Power-loss durability depends on the receiving database's - documented SQLite synchronization policy; lifecycle import and acknowledgment must use - the stronger policy if Orca promises survival across sudden host power loss. -

- -
- - - - - - - - - - - - - - - - - - - - - - - - - -
MechanismWhy it staysWhy it is not a scheduler
Server ownershipPrevents commands from acting on a same-looking resource on the wrong host.The agent chooses --on; the owner only determines routing.
Dispatch identityPrevents stale workers from overwriting current task state.It does not retry, replace, or start anything automatically.
Unknown outcomePrevents duplicate remote effects after a disconnect. - The receipt gives last durable stage and inspection command; the coordinator - chooses inspect, reconcile, retry, or abandon. -
-
- -

- Safety may reject stale, wrong-pane, or wrong-server control-plane mutations. It does - not police worker filesystem access, invent new work, choose a worker, or decide that - waiting is the coordinator's best next action. -

- -

- This federation is deliberately hub-and-spoke per Run: one home, explicit worker - servers, and per-Dispatch relay queues. It does not create a global cluster, replicate - Run state, elect leaders, fail over the home, schedule placement, or require agents to - carry server IDs after start. -

Agent ergonomics

-

The skill should be a cookbook, not a second help page.

-

- orca --help already owns syntax and exhaustive flags. The skill should - teach judgment: which topology to choose, how to preserve parallelism, what the - command returns, and what not to create afterward. -

-
- -
-
-

Parallel fan-out

-

Start every independent task first. Only then call check --wait.

-
-
-

Shared-worktree review

-

Use the current worktree when sharing its exact state is useful.

-
-
-

Independent writers

-

Create separate worktrees when a concrete checkout conflict calls for isolation.

-
-
-

Ask and reply

-

Use a threaded question; continue other work while only that worker is blocked.

-
-
-

Read a full-screen agent

-

Use worker-read --dispatch; Orca routes to the owning server.

-
-
-

Replace safely

-

Inspect the stop result before deciding where to start a replacement.

-
-
- -

- Restart recovery · home and worker server are independent -
-

- A Run-home restart preserves the Run, retry receipts, and the same unacknowledged - Delivery; run-use is needed only when Orca cannot safely remint the - previous coordinator pane. A worker-server restart preserves its Dispatch - attachment and relay queue but does not pretend the agent process survived. - Misuse: starting a replacement merely because a runtime ID changed. -

-orca orchestration worker-show --dispatch dispatch_7 --json
-# running/ready → keep waiting; gone/failed → explicit retry-of; unknown → inspect or stop/abandon.
-
-
- -

- The skill must say that check --wait returns a batch. Process every message - before acknowledging it. -

-

Scenario tests matter more than keyword checks

-
-
    -
  • Reuse the terminal returned by worktree creation.
    • -
  • Start three independent workers before waiting.
    • -
  • Omit runId only when the coordinator terminal is explicitly bound.
    • -
  • Use current-worktree collaborators without unnecessary worktrees.
    • -
  • Fence an old consumer's acknowledgment after run-use rebinds.
    • -
  • Import duplicated and out-of-order relay frames only in contiguous order.
    • -
-
    -
  • Never treat a worker report as verified integration.
    • -
  • Never replay terminal input after unknown acceptance.
    • -
  • Page terminal output by Dispatch; use a session source only when exact.
    • -
  • Inspect an ambiguous remote stop before choosing the next action.
    • -
  • Let the first committed stop/completion transition win transactionally.
    • -
  • Reject a re-paired peer and never adopt a same-looking restarted process.

Complexity audit

Keep only the machinery required by Orca's concrete failure modes.

Observed Orca needKeepDeliberately defer
Lifecycle messages can be lost, injected into prompts, or consumed before a caller receives them.Durable typed mail, explicit acknowledgment, and race-free blocking waits.Dead-letter workflows, priority schedulers, watchdog policy, or a second queue product.
Terminal scrollback is not always the best available source, but session identity can be ambiguous.Terminal output as the baseline and an optional exact, source-pinned adapter.A universal session ontology, resume layer, or global provider exclusivity.
Remote acceptance, process exit, and worker claims provide different levels of evidence.Explicit lifecycle, fenced replacement, and typed unknown-outcome handling.Automatic retry, inferred success, rollback, or generalized recovery policy.
A Run home must coordinate workers across restarts and connected Orca servers.Stable Run, Task, and Dispatch identity with authenticated server relay.Role simulation, worker scoring, organization models, or integration queues.
-
- -
-
-

Tests prove the contract

-

- Scenario tests must demonstrate durable messages, authenticated relay, lifecycle - fencing, and truthful recovery. Design analogy is never a substitute for an - Orca-local executable contract. -

-
-
-

Complexity requires local evidence

-

- A generalized scheduler, fairness policy, dead-letter workflow, or integration - system should be proposed only after Orca users demonstrate that the simpler - primitives cannot solve a recurring problem. -

-
-
- -

- Blocking wait, crash-safe acknowledgment, and connected-server relay require - Orca-local implementation and tests. Structured output reuses Orca's exact - pane/process-to-provider-session association and existing bounded transcript decoders; - it does not introduce provider-session control or a universal transcript model. -

-
- -
-
-

Implementation order

-

Each phase should remove one concrete source of agent confusion.

-

- There is no UI phase. Each runtime change ships with a version-matched example and a - misuse test so the skill and behavior cannot drift apart. -

-
- -
-
-
Phase 0
-
-

Rewrite the orchestration skill as recipes

-

- Teach correct fan-out, current versus new worktree selection, startup terminal - reuse, --setup run for new worktrees unless the agent states a - concrete reason to skip or inherit, while preserving the existing - start-immediately default, current batch behavior, and blocking only - after useful parallel work is exhausted. Correct the one-message claim and - document today's delivery limits. - Rename or remove the existing scheduler-like orchestration run --spec - command before the lightweight run-* vocabulary can ship. -

-
-
-
-
Phase 1
-
-

Run mailbox, truthful completion, and crash-safe consumption

-

- Add explicit Run-home binding, stable logical recipients, strict - inbox-only structured mail, succeeded/failed worker outcomes, one outstanding - FIFO batch, explicit acknowledgment, typed timeout results, ask/reply state, - a narrow runtime-minted Dispatch capability carried by the CLI bridge, and - resume-by-message-ID after a disconnected ask. Migrate existing global rows to - one unbound inspect-only legacy Run; do not infer bindings. Do not add separate - Question IDs or expiry policy. -

-
-
-
-
Phase 2
-
-

Local synchronous worker start and control

-

- On the Run home, compose existing worktree, setup, terminal, and dispatch - primitives with setup-run as the new-worktree default, a durable request/stage - receipt, side-by-side setup/agent startup by default, startup-terminal reuse, - exact readiness, and Dispatch-routed - show/read/stop/abandon. Prove current, existing, - child, top-level, failure, restart, and unknown-outcome behavior before adding a - network boundary. Do not add a background provisioning executor. -

-
-
-
-
Phase 3
-
-

Connected-server Dispatch and relay

-

- Extend the same primitives with saved-environment placement, pinned peer identity, - remote Dispatch attachments, paired-server calls, and bounded bidirectional relay - with contiguous cursors and idempotent acknowledgment. Validate Mac-home/Windows- - worker and Windows-home/Mac-worker completion, question/reply, read, stop, - either-side restart, re-pairing, disconnect, and mixed versions—without Run - replication, failover, or scheduling. -

-
-
-
-
Phase 4
-
-

Exact structured worker output

-

- Reuse Orca's existing pane-scoped hook association and bounded - Codex/Claude/OpenClaude/Grok transcript decoders. Add - auto|transcript|terminal selection, - path-free source identity, opaque source-pinned paging, and labeled terminal - fallback without adding provider control or a universal transcript layer. -

-
-
-
- -
-
-

Success looks like

-
    -
  • Agents start all independent work before waiting.
    • -
  • Lifecycle messages never flood editable coordinator input.
    • -
  • One Run can supervise Mac and Windows workers through one home inbox.
    • -
  • Remote completion and replies survive either server temporarily disconnecting.
    • -
  • No delivery is consumed before explicit acknowledgment.
    • -
  • Failed worker reports set failed—not completed—and remain worker assertions.
    • -
  • Worker start never reports a resource created before it exists.
    • -
  • Full-screen agent output remains readable when an adapter supports it.
    • -
  • Stale, wrong-pane, or wrong-server workers cannot mutate current task state.
    • -
-
-
-

Complexity budget

-
    -
  • No new concept without a common recipe that needs it.
    • -
  • No automatic action whose trigger an agent cannot explain.
    • -
  • No provider field that an adapter cannot actually observe.
    • -
  • No hidden default omitted from the operation receipt.
    • -
  • No control-plane fact derived from untrusted transcript prose.
    • -
  • No future feature included merely to keep the architecture open-ended.
    • -
-
-
-
- -
-
-

Explicit boundaries

-

What this proposal intentionally does not build.

-

- These are not hidden later phases. They require separate evidence and a separate - proposal if Orca eventually needs them. -

-
- -
-
-

No product UI

-
    -
  • No dashboard or run/task view
    • -
  • No global inbox, badges, or queue screen
    • -
  • No coordinator chat surface

- Could Orca add these things later? -
- Yes, but strong primitives do not need speculative abstractions for them today. A - future feature should compose the same start, message, wait, read, stop, identity, - and ownership contracts. It should justify its own concepts from observed Orca use. -
-
- -
- Does removing commit tracking make worker results less trustworthy? -
- It makes the contract more honest. Today Orca verifies who is authorized to report a - result, not that every claim inside the result is true. A coordinator may explicitly - ask another worker to review or run validation. That is agent-directed orchestration, - not an implicit integration subsystem. -
-
- -
- What about connecting multiple Orca runtime servers? -
- It is a core requirement. A Run stays authoritative on one home server while remote - Dispatches execute on saved connected environments such as a Windows machine. - Authenticated routing plus a small durable relay carries lifecycle mail and replies - across disconnects. This intentionally stops short of a global cluster: no Run - replication, leader election, automatic failover, distributed scheduler, or lease - manager is required. -
-
- -

- Phases 0–4 of this contract are implemented. Structured output is verified locally, - through a mixed-version terminal fallback, and across a Windows-home to Mac-worker - Dispatch; the remaining physical symmetry checks stay in the acceptance ledger. The - proposal makes no Orca product UI changes. -

The handler then chooses the first truthy scope and treats zero truthy scopes as `all`, so `{}` wipes everything and contradictory inputs such as `{ tasks: true, messages: true }` partially apply the first truthy branch. - -## Non-goals - -- Redesign orchestration storage or reset semantics. -- Add confirmation prompts to the RPC protocol. -- Change `resetAll`, `resetTasks`, or `resetMessages` database behavior. -- Change unrelated orchestration commands or provider-specific behavior. - -## Design - -1. Enforce exactly one truthy reset scope at the `ResetParams` schema using `superRefine`. -2. Remove the handler fallthrough to `db.resetAll()` so only validated explicit scopes can mutate state. -3. Preserve the existing CLI no-flag shortcut by having [src/cli/handlers/orchestration.ts](/Users/jinwoohong/orca/workspaces/orca/bug-orchestration.reset-wipes-all-orchestration/src/cli/handlers/orchestration.ts:440) pass `all: true` when no reset scope flag is present.

Duplicating scope validation in the CLI is unnecessary because all CLI calls already pass through this RPC method. -5. Add RPC regression tests that seed one message and one task, call invalid reset params, assert rejection, and assert both seeded records remain. -6. Add CLI parser tests that `orca orchestration reset` calls RPC with `all: true`, and that explicit flags are passed through unchanged for RPC validation. - -## Data Flow - -- CLI no-flag path: `orca orchestration reset` -> CLI handler sends `{ all: true }` -> RPC schema validates -> handler calls `resetAll`. -- CLI explicit-flag path: CLI handler forwards the provided flags -> RPC schema validates exactly one truthy scope -> handler calls one database reset method or rejects before side effects. -- Direct RPC path: caller params -> RPC schema validates exactly one scope -> invalid params fail before handler side effects. - -## Edge Cases - -- `{}` rejects and leaves messages and tasks unchanged. -- `{ all: false }` rejects and leaves messages and tasks unchanged. -- `{ tasks: true, messages: true }` rejects and leaves messages and tasks unchanged. -- `{ all: true, tasks: true }` rejects and leaves messages and tasks unchanged. -- `{ all: false, tasks: true }` is valid and resets tasks only; false values are not selected scopes. -- Non-boolean values such as `{ all: "true" }` are transformed to `undefined` by `OptionalBoolean` and must reject unless exactly one real boolean `true` is present. -- Explicit `{ all: true }`, `{ tasks: true }`, and `{ messages: true }` continue to work. -- Remote and SSH callers are covered because the validation sits behind the shared RPC method, not local CLI process state. -- Unknown keys do not select a scope.

CLI no-flag compatibility remains a CLI concern by passing `all: true`. -- Failure modes covered: - - Empty reset params cannot mutate state. - - Contradictory scopes cannot partially apply the first truthy branch. - - Failed validation happens before any database reset method runs. - - CLI shorthand cannot rely on a dangerous RPC fallback. - - CLI multi-flag input fails through the same RPC validation as any other caller. -- Test coverage required: - - `src/main/runtime/rpc/methods/orchestration.test.ts`: reject empty, false-only, and multi-scope params while preserving seeded message/task state. - - `src/main/runtime/rpc/methods/orchestration.test.ts`: existing valid single-scope tests continue passing. - - `src/cli/index.test.ts`: no-flag CLI reset passes `all: true`; explicit flags and multi-flag input remain directly represented. -- Performance/blast radius: No material concern. One tiny schema refinement and branch simplification run only when reset is invoked. -- UI quality bar: Not UI-visible. -- Required review screenshots: None; final validation notes should explain that screenshot capture is skipped for headless RPC/CLI behavior. -- Residual risks: CLI users may still accidentally clear all state with `orca orchestration reset` because the compatibility shortcut remains, but direct RPC callers can no longer do so accidentally and CLI behavior is now explicit in the caller. -- Concurrency/consistency: This change prevents invalid reset requests from entering the mutation path, but it does not make the existing multi-statement reset methods transactional or coordinate concurrent reset/create/send calls across windows. That is acceptable for the issue scope because valid resets are still destructive administrative operations; adding reset serialization would be a separate storage-level change. diff --git a/docs/persist-tree-view-source-control.md b/docs/persist-tree-view-source-control.md deleted file mode 100644 index c377c9b82ca..00000000000 --- a/docs/persist-tree-view-source-control.md +++ /dev/null @@ -1,93 +0,0 @@ -# Persist Source Control Tree View Choice - -## Problem or Goal - -The Source Control sidebar lets the user toggle changes between list and tree views, but the choice is session-local.

A sink `write(false)` accepts its frame exactly once. No ordinary frame is - written again before drain. PTY admission stops before a reserved - control/liveness capacity is consumed. -5. A spawn/attach token remains `activating` until its metadata-only response - crosses the relay sink fence. Main may receive source frames after its - synchronous provisional install, but they remain lease-private and cannot - project. A validated reconnect contract transfers that lease into the - attempt's private recovery quarantine; final commit, model, and desktop - admission remain fenced until all recovery `pty.data` and the exact - completion fence agree. -6. Data is ordered within a token. `pty.exit` follows every accepted data frame - and cannot bypass the sink gate or activation fence. Publishing exit seals - new data but does not retire an uncredited suffix. -7. Every open token-owned span and consumer obligation ends exactly once in - `settled`, `transferred`, or `canceled`; a transfer may pass through the - non-terminal `transferring` state only while its named replacement fence is - outstanding. A canceled `restoreRequired` delivery remains addressable until - its exact response settles and retires only if the map still names that - record. Records are never merely abandoned while their relay token can live. -8. Desktop, mobile, web, and agent-session consumers follow the explicit - settlement policy below. A stalled recoverable desktop projection cannot - freeze a healthy lossless remote view. -9. One slow additional subscriber cannot retain unbounded data or stop a - healthy subscriber. The negotiated session owner is not torn down for one - PTY's backlog; constructor position never grants that role. -10. When every delivery for a PTY is blocked, pause the native PTY. Resume only - when both local and relay-wide low-water predicates hold. -11. An unexpected client loss transfers outstanding output to a bounded - reconnect-grace owner. Normal subscriber absence retains only the existing - replay tail and no live queue. -12. Decoder work, decoded bytes, model admission, and activation-hold turns are - bounded. A self-imposed read or local-write pause rebases both liveness - clocks. Main-to-relay drain reselects liveness, then control, ahead of - ordinary PTY input; four consecutive control selections force one ordinary - selection when both lanes remain non-empty. -13. Disconnect, provider replacement, renderer reload, exit, disposal, and - workspace removal have explicit bounded cleanup. After their required - publication, transfer, cancellation, or generation-close proof, they leave - no open span, token, writer callback, drain waiter, timer, cursor, or paused - PTY. Recovery-cancellation publication failure or rejected proof fails - closed by closing only the owning provider generation and disposing its - mux, provider, publishers, transferred activation state, and registration - once. -14. All counters are finite safe integers. A transformed frame requires a - valid `rawLength`; malformed, excessive, stale, and cross-client values - cannot create credit or crash either process. -15. The session owner is elected by an authenticated session grant and - identified by an owner generation. It is never inferred from dispatcher - construction, stdout, socket order, a path, `.git`, or a worktree. -16. Recovery and serialization control responses contain metadata only. - Source-ranged recovery or snapshot bodies use bounded producer lanes and - explicit completion fences before live delivery. -17. The required main model has bounded asynchronous admission. Relay credit - cannot advance while data waits outside that charged admission or after an - emulator failure. -18. Negotiated V1 has one upstream ACK owner. Renderer projection progress and - remote encoded-byte ACKs settle ledger obligations but never emit legacy - SSH ACK deltas. -19. Required obligations becoming terminal, cumulative ACK queueing, and ACK - publication are three monotonic states. A write callback publishes already - eligible credit; it never creates eligibility. -20. Desktop admission carries immutable span identity through model reserve, - projection queue, renderer send, ACK, salvage, reload, and replacement. - Failure either rolls back an uncommitted transaction or transfers a - committed obligation with proof. Exit timeout acquires cancellation proof - without mutation, transfers published projections, commits proof - reclamation, prepares/finalizes exit once, and rechecks the provider - generation before each post-proof mutation. -21. Projection drop, thinning, salvage, restore, and replay preserve current - main's ordered terminal side-effect facts and bounded scanner state, - including DEC mode 2031 subscribe/withdraw decisions. Pre-commit rollback - restores the prior scanner snapshot, committed transfer moves projection - state exactly once, and an explicit source gap resets cross-chunk state; - none of these facts creates source credit. -22. The immutable delivery identity is exactly `(id, providerGeneration, -clientGeneration, ownerGeneration, ptyIncarnation, deliveryToken)`. Each - admitted source span additionally fixes `spanId`, source/display half-open - ranges, transform metadata, and model-sequence end where required. -23. Receive activation begins at `checkpointSourceEndSu`. Every recovery - `pty.data` frame is contiguous from that cursor through `recoveryEndSu`; - only the exact `pty.recoveryComplete` writer settlement opens live output. -24. A reentrant cumulative ACK may reserve only the exact pending send - boundary for the same delivery identity. Failed send settlement retains - that boundary and permits only an exact same-token retry. -25. A fixed `fs.streamChunk` keeps the protocol's 256 KiB payload and offset - semantics. It may use the fixed-frame lane only from an empty, - unsaturated producer epoch; ordinary PTY and reshapable bulk frames still - obey the non-reserved capacity. -26. A lossless remote stream may advance its cumulative encoded-byte ACK to an - interior byte offset. Exact byte budget is released immediately, while the - covering immutable source frame remains unsettled until its complete - encoded boundary is crossed. -27. A lossless remote stream accepts an in-place source-token rotation only - when PTY ID, provider generation, and incarnation match; both client and - owner generations strictly increase; the token changes; and source/display - coordinates remain contiguous. Old or partially increasing identities are - rejected. -28. Snapshot replacement commits are idempotent and never synthesize byte or - source credit. Duplicate/closed ledger commits are no-ops; if cancellation - proof already reclaimed a reserved span, source replacement commit rejects, - rollback skips the absent span, and settle/detach prune cached mappings. -29. Exact exit seals a provisional or private-recovery receive lease before - any later same-token frame can reserve or project. Exit publication waits - for the held contiguous prefix to admit or for cancellation proof whose - sent end covers every privately observed exact-token frame. -30. Transfer does not consume rollback authority until the ledger proves the - lease is still current and installs the private recovery sink. A stale - transfer can still retire and cancel only its own token. -31. Canceled-frame suppression retains at most one latest ordered delivery - identity per relay PTY. Transport ordering makes earlier token records - obsolete when a later cancellation is observed; exact next activation, - PTY exit, or provider teardown clears the remaining record. - -## Protocol - -### Architecture decision record - -Decision: `PtyConsumerSession` is a shared semantic state machine, not a -universal transport protocol. The architecture gate is closed and is no -longer waiting for exact wire/API names: the SSH adapter implements -`sourceActivation`, source-bearing `pty.data`, `pty.recoveryComplete`, -cumulative `pty.ackData`, and token-scoped cancellation. Current-working-tree -deterministic validation is an engineering gate; unexecuted live topologies -remain separate promotion gates. A relay-only -`pty.getCapabilities` followed by `pty.negotiateClient` remains rejected -because it would create a second readiness authority beside the existing -authenticated handshakes. - -The 2026-07-28 architecture/terminal review closed its three blocking -findings as follows: - -| Finding | Implemented resolution | -| ------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -| Exited delivery removed while uncredited spans remain | Native exit seals the token; logical state survives until cumulative ACK, exact transfer, token-scoped cancellation proof, or generation close. | -| Terminal obligations depended circularly on ACK publication | Obligation terminality advances `obligationsTerminalEndSu`; the coalescer independently queues `ackQueuedEndSu`; only mux write settlement advances `ackPublishedEndSu`. | -| Desktop projection admission lacked immutable range identity and rollback | Model, source span, projection range, and scanner snapshot reserve atomically; pre-commit failure rolls back, while post-commit replacement transfers with proof. | - -Later adversarial review also required exact recovery continuity, stale-attempt -isolation, session-grant fallback semantics, and idempotent remote detach -after token reclamation. Those are incorporated in the activation, lifecycle, -cleanup, tests, and compatibility sections below. - -The final 2026-07-28 architecture/terminal re-review found and closed three -additional interleavings: - -| Finding | Implemented resolution | -| --------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -| Failed exit publication could discard a sealed delivery before its suffix was credited | Failed publication retains the sealed delivery; late cumulative ACK and exact owner recovery can still settle it, and exit is republished without reopening source admission. | -| Recovery-response cancellation authority ended at enqueue rather than writer settlement | The request remains cancellation-authoritative until its response settles; retry reuses the same provisional replacement identity instead of creating an unfenced owner. | -| Snapshot replacement transferred every pending remote span at one sequence fence | Each immutable span retains its model-sequence end; replacement transfers only spans covered by the authoritative `SnapshotEnd`, while trailing spans remain live and replay in order. | - -Current-working-tree adversarial reconciliation closed these additional integrated -failures without widening the approved topology: - -| Finding | Implemented resolution | -| ---------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -| Invalid-checkpoint `restoreRequired` left a canceled delivery blocking retry | Keep the exact canceled record through response settlement, then delete it only if it is still current; retry mints a fresh activation token. | -| Recovery cancellation publication/proof rejection left ambiguous authority | Raise a typed recovery-cancellation failure and close the exact provider generation, disposing its mux, provider, publishers, lease, and registration exactly once. | -| Remote partial ACK or higher-generation token rotation detached the stream | Release exact cumulative byte credit at any valid interior offset without source settlement; admit only contiguous strictly higher client/owner generations with a new token. | -| Snapshot cleanup raced cancellation-proof reclamation | Make ledger replacement commit idempotent and make remote replacement commit reject reclaimed spans while rollback, settle, and detach prune them without dereference or new credit. | -| Drain resumed the main mux's old ordinary FIFO ahead of control | Select liveness, control, and ordinary from separate FIFO lanes; prioritize control after drain and force one ordinary write after four controls. | -| Same-turn source data escaped a provisional activation | Queue data privately under the provisional lease; commit publishes in order, while rollback drops it, restores only the active predecessor, and awaits exact cancellation proof. | -| Exit cancellation proof reclaimed spans before projection transfer | Acquire proof first, transfer projections, commit proof, prepare/finalize once, and fence every post-proof step against provider-generation close. | -| Exit during private recovery could publish before held frames settled | Seal the private lease immediately, wake the exact recovery fence, then either admit the ordered prefix before exit or retire it only after exact token-cancellation proof. | -| A superseded transfer lost its cancellation authority | Keep the outer lease unsettled until transfer ownership is verified; a stale transfer can still roll back and request cancellation for its exact token. | -| Recovery proof watermark skipped rejected or post-restore frames | Observe every exact-token private frame before retention or restore checks and reject any cancellation proof whose sent end is below that immutable high-water. | -| Canceled-token tombstones grew once per token | Retain only the latest ordered canceled token per relay PTY, replace it on later cancellation, and clear it at exact next-activation, PTY-exit, or provider-teardown boundaries. | -| Reconnect checkpoint raced a running raw model callback | Freeze the exact provider-generation/PTy admission, cancel only queued work, and await the bounded running callback before exporting a checkpoint. | -| Migration-owned callback failure closed the shared provider | Contain failure to the exact migrating PTY, reset only its model, preserve siblings and transport, and retain the ordinary generation-fatal policy outside migration. | -| Closed-generation telemetry omitted active gaps | Compact exact closed ranges and expose the count of allocated but unclosed provider generations below the closed high-water. | - -The final exact-implementation-head architecture/lifecycle review was clean -across 27 files and 296 tests. The transport/topology review confirmed the -exact-PTY containment fix and found no remaining code blocker; its sole -evidence finding was the stale artifact record replaced by the -provenance-bound build and Docker run above. - -The common state machine accepts only: - -- an authenticated principal and owner-eligibility decision from the adapter; -- a consumer generation and optional capability offer/grant; -- a subscription/delivery identity and close reason; -- an adapter-provided publication fence. - -It does not authenticate sockets, parse frames, own sentinel/residue bytes, -wait for stream drain, prove reconnect credentials, or define remote-runtime -encoded-byte ACKs. Those remain adapter responsibilities. The semantic input -and output may be represented as: - -```ts -type PtyConsumerSessionHello = { - clientInstanceId: string - requestedRole: 'session-owner' | 'subscriber' - resume?: { - ownerGeneration: number - ownerLease: string - } - capabilities?: { - outputFlowControl?: { versions: [1]; requestedWindowSu: number } - } -} - -type PtyConsumerSessionGrant = { - serverBuildId: string - clientGeneration: number - role: 'session-owner' | 'subscriber' - ownerGeneration?: number - ownerLease?: string - capabilities?: { - outputFlowControl?: { version: 1; windowSu: number } - } -} -``` - -These types are not wire schemas. Authentication produces a transport-bound -principal and `allowSessionOwner` before the state machine sees the offer. A -request field cannot self-promote a client. The state machine performs -generation allocation, owner replacement, capability intersection, -publication fencing, and close cleanup; the adapter proves identity, carries -the semantic fields, and calls the fence. - -The reviewed decision preserves the existing connection machinery: - -| Path | Authentication and identity | Binding in this PR | -| --------------------------------------- | ---------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------- | -| Local in-process provider | trusted main-process construction | unchanged; it does not negotiate SSH V1 | -| Local daemon | token-authenticated `HelloMessage`, stable `clientId`, paired control/stream sockets, and `daemonIdentity` | unchanged; an exact-version daemon remains outside the SSH wire contract | -| SSH relay socket/named pipe | existing authenticated relay endpoint and dispatcher client identity | first framed `pty.openClient`; response settlement is the readiness fence | -| Primary relay stdio and WSL child stdio | no authenticated dispatcher principal in this PR | bounded legacy transport only; an unproved client cannot become session owner | -| Remote-runtime server | paired-device/E2EE identity and connection ID | source-range reserve/commit/rollback only; never receives an SSH owner lease | - -The implemented owner path is the authenticated detached relay endpoint used -by the SSH provider. After extracting the exact sentinel and residue, main -sends `pty.openClient` before spawn, attach, or ordinary dispatch. The relay -adapter queues later decoded frames behind the session response's write -callback, so an eager next request cannot race activation. Main marks the -provider ready only after receiving the valid response. - -Detached `--connect` first reads the version-scoped endpoint credential and -authenticates its Unix-socket/named-pipe bridge before emitting its sentinel. -The adapter converts that proof into a principal and -`allowSessionOwner = true`; `pty.openClient` carries no secret to the generic -RPC handler. The primary relay stdin/stdout dispatcher identity remains -explicitly unproved and therefore subscriber-only; there is no launch nonce in -this implementation. WSL child stdio shares the bounded decoder/writer -transport changes but does not negotiate an SSH V1 owner in this PR. A manual -relay without the version-scoped endpoint credential is also subscriber-only. - -POSIX hosts may expose different shell and SFTP home namespaces. While the -install lock is held, a per-launch marker maps the canonical shell credential -path to the matching SFTP-relative path; the credential write uses that -mapping before the lock is released. If the marker is unavailable or its -creation fails with confirmed termination, main generates the credential -remotely with the selected Node binary at the canonical shell path. System SSH -keeps its shell-path writer, Windows keeps its native secure writer, and the -remote CLI launcher receives the same credential-file path. An unconfirmed -marker teardown retains the lock rather than authorizing a competing writer. - -The review compared sentinel extension and the single request against one -readiness authority, no first-spawn race, authenticated owner replacement, -response publication fencing, reconnect idempotency, exact residue transfer, -and deterministic testability. The single request wins for the authenticated -deployed-relay bridge. A separate capability probe, two-step negotiation, and -a generic cross-transport wire API are not approved. - -The local daemon adapter is deliberately not changed in this PR. Its existing -sequential control/stream hello, authentication, exact-version fencing, and -prior-version isolation remain authoritative. Reusing the semantic state -machine there is a later design decision and is not required to ship the SSH -bound. - -Every new SSH session offers V1, and every relay from the same build advertises -V1. The server intersects the offer with its supported versions and clamps -`windowSu`; an older client that omits the capability receives bounded legacy -delivery while still establishing the role and generation. Main accepts only -a returned version it offered and a finite safe integer satisfying -`0 < windowSu <= requestedWindowSu`. An absent or invalid V1 grant after -`pty.openClient` succeeds closes that connection attempt rather than silently -downgrading it. - -For compatibility with a legacy relay that does not implement -`pty.openClient`, main permits token-free bounded legacy delivery only for the -narrow same-build-validated JSON-RPC method-not-found result. Other errors, -missing grants after a successful method call, and unproved version skew fail -closed. This fallback does not change the normal same-build contract: the -session offers V1 and the relay advertises and grants it. - -“Bounded legacy” is transport backpressure, not a hidden source-credit mode. -It creates no delivery token, source window, or cumulative ACK obligation, and -the relay continues to ignore legacy `pty.ackData`. Slice 3 retains at most -2 MiB of ordinary publications per client and 32 MiB across the relay, with -1 MiB/24 MiB low waters, plus at most one 128 KiB producer-held frame per PTY. -At a cap, `PtyHandler` pauses the PTY; accepted write callbacks/drain remove -transport publications, and crossing both low waters resumes it. Slice 2/4 -read pauses propagate through SSH until the relay writer saturates, so stalled -model admission remains bounded without pretending renderer ACKs reached the -relay. - -Legacy exit waits only for preceding transport publications and the exit write -callback; main's receive-exit barrier below still waits for its admitted model -and projection work. Transport close cancels the connection's retained -publications and reconnect uses the existing replay/restore behavior. It may -pause all legacy subscribers behind one slow connection because legacy mode -has no authenticated source-owner role, but it neither drops output nor grows -without bound. These mechanics remain available to negotiated legacy peers. - -The session hello creates no PTY token. A later V1 spawn/attach returns a fresh -`deliveryToken` and creates a subscription only for the authenticated -transport client and installed generation. `pty.attach` must receive request -context just as `pty.spawn` does. Spawn failure, identity mismatch, stale -context, and response cancellation create no active V1 subscription. A legacy -spawn/attach returns the current identity/replay shape and creates only the -bounded transport subscription above—no token or source coordinate. A live V1 -token never rotates into legacy service; disconnect closes it before any -separately negotiated legacy fallback connection can open. - -Session ownership is granted by the authenticated session hello, not -constructor-assigned: - -- fresh relay deploy writes one endpoint credential beside the versioned - endpoint, reusing the local daemon's token-authenticated-hello pattern rather - than inventing a second claim protocol. It has mode `0600` on POSIX or a - current-user ACL on Windows. `--connect` proves it; a plain dispatcher socket - without the credential is subscriber-only. Primary relay stdio and WSL - child stdio remain unproved bounded-legacy transports. The adapter converts - proof into `allowSessionOwner = true` and does not expose the credential to - RPC handlers; -- the main creates one opaque `clientInstanceId` for its relay-session - lifetime. The first authenticated owner hello when no owner exists binds - that identity, returns a lease, and starts owner generation 1; -- until that first grant crosses its write fence, a retry with the same - authenticated identity is idempotent and any competing identity is rejected. - Once fenced, replacement requires both the current lease and expected - generation; -- an unexpected owner disconnect retains that lease and its PTY grace cursors - for 30 seconds. A reconnect presenting the lease and expected owner - generation atomically increments the generation, rotates the lease, replaces - the old client, and transfers grace ownership before any new token activates; -- a same-generation retry is idempotent only for the same live client. - Competing, stale, lease-less, or unauthenticated identities cannot replace - the owner and may connect only as ordinary subscribers; -- after grace expiry, the old owner lease is invalidated and the next - owner-authorized session hello can elect a new owner at the daemon's next - monotonic owner generation; generations are never reused. Ordinary - subscribers never inherit owner teardown protection merely by arriving first. - -Source activation, `pty.data`, recovery completion, ACK, and cancellation -carry client/owner generations and the delivery token. `pty.exit` retains its -existing PTY ID plus incarnation shape and resolves against the already -installed delivery identity; it cannot create or rotate one. Main rejects a -generation other than the one installed by its synchronous response hook. The -constructor stdout client is never implicitly a session owner. Production -launches detach on POSIX and Windows, invalidate stdout, and connect the -desktop bridge through `attachClient` over the versioned Unix socket or named -pipe. Unproved direct stdio remains subscriber-only. - -Capability support is negotiated on every SSH session. `SshRelaySession` -always offers V1 during initial connection and automatic reconnect, and POSIX -and Windows relays always advertise it as an unconditional capability. Sink -drain, writer ordering, decoder bounds, and header-ACK hardening remain -unconditional correctness fixes. - -Production deployment does not form arbitrary mixed-build main/relay pairs. -`computeRemoteRelayDir` content-hash-scopes the install directory and its -socket/named-pipe endpoint, and the `.version` handshake is a second fence, so -the desktop bridge and daemon reached at that endpoint share a build. The -normal same-build mode is session-granted V1. A missing mandatory session grant -fails readiness except for the narrow method-not-found compatibility fallback -above. Protocol tolerance for unknown fields remains for direct/manual relay -launches, but an absent session contract outside that fallback is diagnostic -`unsupported-version-skew`, not a deployment cohort. - -The reachable upgrade skew is an orphaned prior-version daemon in its old -version directory with live PTYs while the new main connects to a new endpoint. -It retains its old behavior until its own grace/cleanup completes and is not -reachable by a new same-build session. Upgrade diagnostics enumerate -these versioned orphan processes; V1 neither adopts their PTYs nor claims to -bound their memory. - -Unknown fields are never capability proof. Place the transport-neutral state -types with the narrowest shared session package, while relay/daemon/runtime -wire types remain in their current protocol packages. Do not make the local -provider depend on relay framing for code reuse. - -### Data and ACK schema - -Flow-controlled output is: - -```ts -// relay -> one subscribed client -{ - jsonrpc: '2.0', - method: 'pty.data', - params: { - id: string, - ptyIncarnation: string, - data: string, - deliveryToken: string, - clientGeneration: number, - ownerGeneration?: number, - sourceEndSu: number, - sourceLengthSu: number, - seq?: number, - rawLength?: number, // required and equals sourceLengthSu when transformed - transformed?: true - } -} -``` - -For untransformed frames, `sourceLengthSu = data.length` and `rawLength` is -absent or equal. For `transformed: true`, `rawLength` is required, finite, -safe, non-negative, and equals `sourceLengthSu`; display length is never used -as source credit. A violation cancels the token as malformed. `sourceEndSu` is -the monotonic cumulative coordinate within one opaque `ptyIncarnation`, not a -display offset. A new token starts with `sentEndSu == creditedEndSu` at its -declared checkpoint, so its absolute coordinate still satisfies the window -equation. The source interval is -`[sourceEndSu - sourceLengthSu, sourceEndSu)`. It is independent of `seq`, -which remains the terminal-model source sequence. - -The wire does not send `providerGeneration` or `spanId`. Main supplies its -locally allocated provider generation and derives -`spanId = deliveryToken:sourceStartSu:sourceEndSu`; together with `id`, -client/owner generations, incarnation, token, source/display ranges, and -transform metadata, that forms the immutable admission identity. No later -queue, snapshot, ACK, detach, or replacement path may reconstruct identity -from PTY ID, byte count, or display length alone. - -ACKs are cumulative and coalescible. Main holds the latest settled end per -token and emits at most one batched notification per SSH session every 8 ms, -or immediately when any token frees at least 64 Ki su: - -```ts -{ - jsonrpc: '2.0', - method: 'pty.ackData', - params: { - acknowledgements: Array<{ - id: string, - deliveryToken: string, - clientGeneration: number, - ownerGeneration?: number, - creditedEndSu: number - }> - } -} -``` - -One frame contains at most 64 latest-value entries; another turn handles the -remainder. Replacing a queued entry for the same token is lossless because the -value is cumulative. ACK frames use the reserved control lane and never one -frame per data frame. - -The relay normally accepts an entry only from the owning dispatcher client and -only when `creditedEndSu` is a finite safe integer satisfying -`previousCreditedEnd <= creditedEndSu <= sentEnd`: - -```text -if creditedEndSu > previousCreditedEnd: - creditedEnd = creditedEndSu -``` - -Negative, non-finite, unsafe, fractional, over-credit, wrong-client, wrong-PTY, -unknown-token, and stale-token values are rejected and counted diagnostically; -they never clamp into valid credit. Duplicate and regressing values are -no-ops. Token generation, not PTY ID reuse, defines the credit lifetime. - -The writer callback is not guaranteed to run before main processes and ACKs an -accepted frame. If an ACK reaches the relay while that exact same-token send -reservation is pending, the ledger records only its exact source-end boundary; -`sentEndSu` and `creditedEndSu` do not advance yet. Successful send settlement -commits the boundary and immediately applies the reservation. Failed -settlement rolls back the send but retains the reserved boundary, so the next -send must reproduce that exact boundary and cannot admit a shorter or later -slice. Cross-token, interior-boundary, and excessive early ACKs remain errors. - -Explicit cancellation is a request so main receives proof: - -```ts -// main -> relay -{ - method: 'pty.cancelDelivery', - params: { - id: string, - deliveryToken: string, - clientGeneration: number, - ownerGeneration?: number - } -} -// result -{ canceled: true, sentEndSu: number, creditedEndSu: number } -``` - -The relay validates client/PTY/token ownership, changes the token to `closing`, -removes its cursor and activation/exit fences, then responds through the control -lane. Duplicate cancellation of the same recently closed token is idempotent. -Main may discard open obligations only after this response drains back through -the mux or the client-generation close proves equivalent cleanup. - -Every relay-initiated token close emits this metadata-only control -notification before the token record is forgotten: - -```ts -{ - method: 'pty.deliveryCanceled', - params: { - id: string, - deliveryToken: string, - clientGeneration: number, - ownerGeneration?: number, - reason: string, - sentEndSu: number, - creditedEndSu: number, - remainingStartSu: number, - remainingEndSu: number, - replacementDeliveryToken?: string - } -} -``` - -It covers supersession, activation/exit timeout, reconnect-grace expiry, and -explicit delivery cancellation. `remainingStartSu == creditedEndSu` and -`remainingEndSu == sentEndSu` state the exact source interval still unsettled -at the relay. If the sink cannot drain the proof, its generation close is the -proof. Without a replacement, main cancels the matching remaining obligations -and schedules restore/reattach. With a replacement, it keeps those obligations -in `transferring` until replacement `pty.data` and its fence prove exact contiguous -coverage, then atomically transfers the covered suffix. Any prefix already -included in the proved model checkpoint is canceled as superseded without -re-ingestion; an uncovered or mismatched remainder cancels with -`restoreRequired` instead of being credited. Every source subrange therefore -settles once. Stale generations are ignored. - -### Activation, replay, and idempotent spawn - -Token creation and response publication are one fenced operation. The exact -activation metadata carried by V1 spawn and attach responses is: - -```ts -type PtySourceReceivingActivation = Readonly<{ - status: 'pending' - clientGeneration: number - ownerGeneration: number - ptyIncarnation: string - deliveryToken: string - checkpointSourceEndSu: number - recoveryEndSu: number -}> - -type SpawnResult = { - id: string - incarnationId: string - sourceActivation?: PtySourceReceivingActivation -} - -type AttachResult = { - incarnationId: string - replay?: string - sourceActivation?: PtySourceReceivingActivation - sourceRecovery?: - | PtySourceReceivingActivation - | Readonly<{ status: 'restoreRequired'; reason: string }> -} -``` - -The dispatcher places the metadata-only response on the response lane and -invokes the request's `onResponseSettled` callbacks only from the exact writer -settlement. Success clears relay activation; failure cancels a fresh token or -leaves the exact recovery attempt available to its proved replacement. -Enqueue, `write(true)`, and `write(false)` alone are not activation proof. - -The main mux supplies the receive fence. Spawn and attach requests register a -synchronous `beforeResolve(result)` hook in their pending-request record. -`handleResponse` parses the whole response and provisionally installs -`sourceActivation` before resolving the Promise. The lease captures the exact -prior receive state, candidate token, and a private ordered list of same-turn -source frames. Spawn and non-recovery attach commit only after operation-ID -result, incarnation, claimed-owner, attach identity, stale-attempt, and exit -validation. Reconnect first validates the owner, incarnation, token, -checkpoint, and recovery end, installs the exact private quarantine, then -transfers the lease to its private sink before awaiting the body/completion -fence. That transfer cannot update ordinary provider listeners or -`livePtyIds`, and it cannot reach the model, runtime, desktop, or remote -consumers. Final commit switches future exact-token frames to ordinary -publication only after the body, fence, model admission, and activation -validation succeed. Any failure before transfer -retires the candidate and drops its held data, restores only the nearest -non-retired predecessor, then waits for a valid `pty.cancelDelivery` response -from the originating mux. After transfer, recovery cancellation or -provider-generation close owns cleanup; rollback is no longer authoritative. -It cannot erase a newer revision or cancel a newer token. An identical -already-committed activation is an idempotent no-op; an identical provisional -activation is stale. Fresh-spawn rollback that cannot prove cancellation -surfaces `execution_owner_unavailable` rather than claiming the old token -retired. - -The receive cursor starts at `checkpointSourceEndSu`, not -`recoveryEndSu`. Source-bearing notifications for the installed identity may -then advance only contiguously. Frames through `recoveryEndSu` stay -quarantined as recovery; later frames stay held until the exact completion -fence commits. Unknown or mismatched source identities are rejected before -`livePtyIds`, runtime, renderer, or source obligations change. Exact -source-bearing frames carry their immutable `ptyIncarnation` directly and do -not invoke or mutate the legacy incarnation resolver. - -Every exact-token private frame advances a monotonic observed-source high-water -before quarantine retention or `restoreRequired` checks. If exact exit arrives, -main wakes the recovery fence and seals the private lease immediately. It may -publish exit only after the held contiguous prefix is admitted, or after -`pty.cancelDelivery` proves `sentEndSu` covers that high-water and the accepted -checkpoint remains the credited end. Capacity-rejected and post-restore frames -therefore cannot disappear below the cancellation proof. - -Output produced while a token is activating is retained by its bounded shared -cursor and can pause the native PTY; it is never sent early. Output arriving -after main's synchronous install but before authority commit is bounded by the -provisional lease and is not visible to runtime, desktop, remote consumers, or -`livePtyIds`. Main drops unknown-token notifications before any side effect. - -Before issuing attach or any same-client replacement, main serializes each -`(providerGeneration, appPtyId)` through a migration fence: freeze new -old-generation intake, cancel queued-but-unstarted model entries, await the one -in-flight emulator callback, then record the last completed receipt. A later -overlapping reconnect preserves and awaits an earlier fence for the same PTY; -an empty newer generation cannot expose the earlier checkpoint. Before the -deadline, every old callback remains owned by its admission and generation -until raw completion settles. Stale-owner retry invalidates the checkpoint -value but retains the same fence, then requests restore after it settles. If -the 10-second migration deadline expires or the callback fails, admission -checks the exact active migration before its generation-fatal default. Main -cancels only that admission, detaches that PTY's old headless model, prefers -provider/renderer snapshot restore, and requests `checkpointUnavailable`; -recovery reports `restoreRequired` instead of replaying a guessed gap. The -shared mux, sibling PTYs, filesystem, and Git traffic remain live. Outside an -active exact-PTY migration, the same callback failure still closes its provider -generation. Late raw completion stays on the detached model and cannot advance -the canceled source checkpoint. - -Attach sends `sourceRecovery: { status: 'checkpoint', clientGeneration, -ownerGeneration, ptyIncarnation, deliveryToken, acceptedSourceEndSu }`. A -queued, in-flight, or merely rendered span is not a checkpoint. Without a -proved fence it sends `{ status: 'checkpointUnavailable' }`. - -The relay accepts the checkpoint only for the same incarnation and within -`[oldCreditedEndSu, retainedLiveEndSu]`. It never clamps a value forward, -trusts a value beyond sent/retained data, or replays freed pre-credit source; -an invalid or uncovered checkpoint cancels the attempted delivery and returns -the token-free `restoreRequired` arm. The canceled record remains installed and -cancellation-authoritative until that metadata response settles. Settlement -deletes it only if the delivery map still points to the exact record and wakes -capacity; a retry can then mint a fresh token. It does not activate a -subscription or stream a partial gap; main either restores an authoritative -model generation before retry or surfaces the gap. - -The reconnect coordinator consumes `restoreRequired` and owns snapshot-backed -replacement. A generic existing-session provider reattach has no such recovery -owner, so it maps `restoreRequired` to `SSH_SESSION_EXPIRED` instead of -returning an outputless live PTY; the existing renderer fallback may then -replace that stale session. - -Recovery bodies use the ordinary source-bearing `pty.data` schema. The new -token initializes `sentEndSu = creditedEndSu = checkpointSourceEndSu`, and -the retained gap covers exactly -`[checkpointSourceEndSu, recoveryEndSu)`. Each frame consumes the normal -window and bounded model admission; there is no separate recovery body method, -stream ID, or replacement-only snapshot kind on this SSH wire. - -Only after the last recovery `pty.data` writer callback succeeds does the relay -attempt this metadata-only control notification: - -```ts -{ - method: 'pty.recoveryComplete', - params: { - id: string, - clientGeneration: number, - ownerGeneration: number, - ptyIncarnation: string, - deliveryToken: string, - checkpointSourceEndSu: number, - recoveryEndSu: number - } -} -``` - -`recoveryCompletionPending` permits one admitted attempt at a time. If control -capacity rejects it before admission, the record retains both range ends and -the capacity callback retries; repeated capacity signals cannot enqueue -duplicates. Only the completion notification's successful writer settlement -clears recovery state and permits buffered live `pty.data`. A failed -settlement leaves recovery fenced for exact owner replacement or cleanup. - -Notification-style `pty.replay` remains the legacy attach compatibility path. -`pty.serialize` remains its existing bounded metadata response; neither is a -second V1 source-recovery body channel. - -Main quarantines the entire candidate recovery transaction until it can prove -the fence. The first source-bearing recovery range must start at the accepted -checkpoint, every later range must be exactly contiguous, and the final end -must equal `recoveryEndSu`. Empty recovery is valid only when the checkpoint -already equals `recoveryEndSu`; main retains that end as the required start of -the first later live frame even after activation. The first live frame and -every successor must also be exactly contiguous. Gap, overlap, incomplete -suffix, missing body, bad empty recovery, or bad live handoff reaches neither -the model nor desktop projection. - -A failed or stale recovery attempt cancels only its own replacement token. -It never sends cancellation on a newer mux, clears a newer checkpoint, shuts -down the physical PTY/process, deletes PTY ownership, or expires the owner -lease. A valid matching token-scoped cancellation proof is applied locally and -leaves the lease detached and retryable. If the current attempt cannot publish -cancellation or local proof application rejects, the session fails closed: -it closes the exact provider generation with -`ssh_source_recovery_cancellation_failed`, disposes that generation's mux, -provider, ACK/cancellation publishers, provisional lease, and registration -once when still provisional, or its transferred activation state after -quarantine ownership begins, and reconnects without clearing physical PTY -ownership. If the attempt is already stale, it performs no cleanup against the -replacement. A fresh -relay that no longer retains the cached owner returns typed error `-32041`; -main clears only the cached owner/checkpoints and retries `pty.openClient` -exactly once without `resume`. - -Idempotent agent-session spawn has two layers. The cached -`agentSessionCreateOperationId` promise returns only the physical PTY -identity/outcome. After that promise resolves, every current, non-stale outer -`pty.spawn` request creates its own requesting-client subscription and -activation fence. Creating a token for an existing -`(clientId, clientGeneration, ptyIncarnation)` is one atomic supersession -transaction: create the replacement cursor first, move the old token to -`closing`, cancel its outstanding activation/exit work, emit -`pty.deliveryCanceled(reason='superseded')`, and return the old token in the -new response. The cancellation names the replacement token and exact remaining -old span. Main transfers that span only after matching recovery completes; -otherwise it cancels it and restores. The pair therefore has at most one -active token and no range is both canceled and replayed as new model input. A -retry served from the cache receives one fresh token, never a duplicate live -subscription. If the client becomes stale after physical commit, no token -survives; the next retry can subscribe to the retained PTY. - -## Relay output architecture - -Split policy from lifecycle and transport: - -- `pty-source-credit-ledger.ts`, `pty-source-credit-record.ts`, and - `pty-source-replay-index.ts` own cumulative token state, immutable retained - source records, exact replay ranges, rotation, and reclamation. -- `relay-pty-source-publication.ts`, - `relay-pty-source-activation.ts`, - `relay-pty-source-send-scheduler.ts`, and - `relay-pty-source-exit-publication.ts` own activation/restore settlement, - 16 Ki-su publication, recovery, exit barriers, budgets, and subscriber - scheduling. -- `dispatcher-client-writer.ts` owns the one writer per sink, activation - fences, lane queues, drain callbacks, and close settlement. - -`PtyHandler` retains PTY lifecycle, the 8 ms initial/1 ms continuation cadence, -immediate interactive/transformed publication, replay tail, streaming -transform state, and idempotent native `pause()`/`resume()`. It publishes -immutable source spans rather than broadcasting notifications. - -### Cumulative span ledger - -Each PTY ledger is append-only until every cursor has passed a span: - -```ts -type RelaySourceSpan = { - spanId: number - sourceStartSu: number - sourceEndSu: number - data: string - splittable: boolean - retainedBytes: number -} - -type PtyDelivery = { - state: 'activating' | 'recovering' | 'active' | 'sealed-unsettled' | 'closing' | 'closed' - clientId: number - clientGeneration: number - ownerGeneration?: number - deliveryToken: string - cursor: { spanId: number; displayOffset: number; sourceOffsetSu: number } - sentEndSu: number - creditedEndSu: number -} -``` - -Different subscribers may stop at different offsets in one span. A cursor -contains both display and source offsets, so no global chunk split can lose or -repeat a suffix. Data storage may coalesce adjacent splittable spans for a -frame or slice one span per cursor; the immutable source boundaries and -cumulative ends do not change. Reclamation requires every live, activating, -sealed-unsettled, closing, or reconnect-grace cursor to pass the complete -span. Native process exit seals admission but does not weaken reclamation. - -The transform publisher cuts source input into scalar-safe pieces, never -between a surrogate pair, and records each display result against its source -interval. An untransformed span may be 16 Ki su and is sliced per sink. -A transformed span is indivisible after publication, so its publisher reduces -the source slice until the encoded span is at most 8 KiB, below the token -window, and no larger than the sink's empty non-reserved capacity. An -implementation that cannot stream a transform must pause before the hard limit -and request model restore; it may not over-credit, truncate, or send an -oversized or permanently inadmissible frame. - -The existing 100 Ki-su replay-tail policy and the chunked -`RecentPtyOutputBuffer` representation from `79ec57d04` remain. -`PtySourceReplayIndex` now provides the bounded parallel source-range index -without restoring the former rolling-string re-slice. Legacy replay still -materializes the same display tail. V1 restore additionally preserves -incarnation, exact source ranges, and transform metadata. Index eviction -follows the buffer's exact retained prefix and never fabricates a mapping; the -existing append-path equivalence/performance contracts remain in force. - -### Scheduling and fairness - -The relay scheduler uses deficit round-robin over PTYs, then rotates subscribed -clients for the selected PTY. One scheduling turn admits at most: - -- two PTY frames; -- 32 Ki su; -- 2 ms of scheduler work. - -Requeue work with `setImmediate` after any limit. Input and control requests can -therefore interleave with output. A recent-input PTY may move to the front once -per round, but repeated interactive classification cannot consume another -PTY's quantum. Preserve the existing bounded interactive fast path: after any -already-queued liveness/control frame, if its token is active, has no earlier -backlog, remaining window covers the exact slice, and the writer admits it -without reserve use, publish one echo frame of at most 4 Ki su immediately -instead of waiting for the 8 ms timer or DRR. Allow at most one such frame per -input epoch; it advances the same cursor once and then yields to normal -priority selection. - -For each live/interactive candidate, all gates must be open: - -```text -frameSourceLengthSu <= windowSu - (sentEndSu - creditedEndSu) -client writer admits PTY bytes without consuming its control reserve -token state == active -``` - -For a splittable span, the admitted slice is at most -`min(16 Ki su, remainingWindowSu)`. An indivisible transformed span is admitted -only when its entire source length fits. There is no one-frame window -overshoot. Dispatcher admission creates one pending send reservation. A -`write(false)` still gives Node that frame exactly once, but the cursor and -`sentEndSu` commit only on successful writer settlement; failure rolls back -the reservation. No later ordinary frame is admitted meanwhile. Unsent frames -remain ledger-owned. Liveness, control, interactive PTY, ordinary source PTY, -and bulk are reconsidered on every writer turn. Recovery and live output use -the same source-bearing `pty.data` producer; recovery additionally requires -`token state == recovering`, exact continuity, byte capacity, and -remaining-window capacity. - -The V1 source owner and additional subscriber projections use independent -publication transactions: -`projectPtyDataToMatchingClients`/`projectPtyExitToMatchingClients` exclude -the `source-owner` and reserve each remaining client separately. If one -additional subscriber cannot reserve bounded writer/publication capacity, -close only that client and continue the healthy subscriber and source-owner -sends; never pause or tear down the native PTY solely for that projection. A -legacy-fallback primary is different: it remains a required bounded-legacy -backpressure participant and is not evicted for saturation. Constructor -position still grants no session-owner role. - -Pause when every remaining delivery is blocked or either retained-byte hard -cap is reached. Resume only when: - -```text -perPtyRetainedBytes <= 1 MiB -relayRetainedBytes <= 48 MiB -at least one delivery can advance, or no delivery remains -``` - -Both predicates are required; the per-PTY low water cannot immediately resume -while the relay-wide budget remains exceeded. Calls are idempotent because a -last `node-pty` callback may re-enter pause/exit handling. - -### Exit - -On native exit, seal the PTY's output stream after publishing the last ingress -emissions. The source-owner delivery changes to `sealed-unsettled`; additional -subscriber exits use their independent bounded projection transactions: - -1. write all preceding data within normal window and drain rules; -2. once that data is accepted by the sink, write `pty.exit` without waiting for - the final data ACK; -3. record the exit write callback as `exitPublished` only on explicit success; - on error, generation-close/cancellation proof owns cleanup. Retain the - delivery, token ledger, cursor, cumulative ACK state, and timeout while any - `[creditedEndSu, sentEndSu)` suffix remains; -4. close only when the outstanding suffix becomes terminal through cumulative - ACK application at the relay, exact transfer to a replacement, explicit - cancellation, or client-generation close proof. - -Never force a final tail past the credit window. An additional subscriber that -cannot admit its projected `pty.exit` is detached without changing the source -owner. For the session owner, cancel only this PTY token after its bounded -deadline, keep the sealed record until ACK, transfer, cancellation, or -generation-close proof, and do not tear down unrelated PTYs. A late valid ACK -against a sealed token remains valid and may complete cleanup. Sealed records -are excluded from the 50-live-native-PTY spawn admission count but remain -charged to retained-data budgets. Relay disposal generation-closes all -records and clears their scheduled work exactly once. Exit listeners and -native PTY disposal run at physical exit; logical delivery cleanup waits for -proof. - -Main has a matching receive-exit barrier. Receiving `pty.exit` seals the token -against later data but does not immediately call `runtime.onPtyExit`, retire -the headless emulator, clear desktop ranges, close remote subscriptions, or -send renderer exit. It retains every preceding model receipt, projection ID, -remote mapping, and ACK publication record. In order, it: - -1. waits for preceding model receipts; -2. publishes or exactly transfers committed desktop ranges and required - remote mappings; -3. advances/queues the terminal cumulative source ACK; -4. then invokes runtime and renderer exit cleanup while retaining ACK - publication state until success or generation-close proof. - -The barrier has the same charged 30-second deadline. At expiry, main first -sends token-scoped `pty.cancelDelivery` and waits up to 10 seconds for its -proof without applying it. If the exact barrier/generation still owns the -exit, main transfers published desktop projections to -`ssh-exit-delivery-canceled`, commits the proof to reclaim source spans, -prepares exit once, rechecks generation ownership, finalizes exit, rechecks -again, then closes the projection. This order prevents proof commit from -reclaiming a span before its published projection transfers. - -If provider-generation close wins while proof is pending, it rejects and -removes the barrier plus its preparation ownership; cancellation ownership is -operation-local rather than retained in a process-lifetime tombstone. The late -proof performs no transfer, commit, preparation, final exit, or projection -close. If cancellation publication or proof fails while the barrier remains -current, main closes the provider so generation cleanup proves cancellation; -unrelated PTYs are not torn down on the ordinary successful timeout path. A -late emulator callback cannot mutate the reset generation. Thus relay sink -ordering and main asynchronous model ordering are both proved. - -Provider generations come from one process-wide monotonic allocator and are -never reused. Main rejects closed generations through sorted, merged inclusive -ranges rather than one retained entry per reconnect. Sequential closes compact -to one range; out-of-order closes preserve exact live-generation gaps until -those generations close, then merge. This keeps stale-generation rejection -exact while retained range count follows live gaps instead of process uptime. - -## Dispatcher and transport drain - -Every dispatcher client is constructed with one bidirectional transport: - -```ts -type SinkWriteResult = 'accepted' | 'saturated' | 'closed' -type SinkWriteSettlement = { ok: true } | { ok: false; error: Error } - -type RelayClientTransport = { - write(data: Buffer, onSettled: (result: SinkWriteSettlement) => void): SinkWriteResult - writableLength(): number - writableHighWaterMark(): number - onDrain(cb: () => void): () => void - pauseReads(): void - resumeReads(): void - close(): void -} -``` - -Adapters map Node `true` to accepted, `false` to saturated, known-dead to -closed, and map the `stream.write(data, callback)` callback's optional error -to explicit success/failure settlement. Only `{ ok: true }` is a publication -fence. A callback error or thrown error closes the client, cancels the -generation, and cannot activate a token, publish ACK state, or release a source -obligation. A saturated or closed transport is never called again for ordinary -traffic before drain/replacement. -One 13-byte keepalive may bypass a saturated epoch; no second liveness bypass -is allowed until that write callback or drain, so the exemption is constant -space rather than an unbounded queue. - -`DispatcherClientWriter` is the only encoder/writer for a client. It owns: - -1. a coalesced liveness lane, at most two 13-byte frames; -2. a FIFO control lane, at most 256 frames and 1 MiB encoded; -3. producer-scheduled interactive PTY, ordinary source PTY, and bulk lanes, - whose frames remain with their producers until the writer admits them. - -It reserves -`min(64 KiB, max(1 KiB, floor(highWaterMark / 4)))` below the stream's -high-water mark for liveness/control. PTY, recovery, and bulk admission all -require -`writableLength + frameBytes <= highWaterMark - effectiveReserve`; the -scheduler reduces source slices and reshapable bulk before publish. The -`fs.streamChunk` wire contract is the exception: its fixed 256 KiB raw chunk -and sequence-offset math are preserved, and the `fixed-bulk` lane admits one -encoded frame only when the producer queue and writable sink are empty and -unsaturated. It then obeys ordinary callback/drain settlement before another -producer frame. No producer writes around these gates. -Every transport accepted for a PTY subscription must expose at least 8 KiB of -empty non-reserved capacity. A lower-capacity subscriber is rejected before -token creation, so an already-published indivisible transformed span cannot -become permanently inadmissible. -Liveness is selected first, then control FIFO, interactive PTY, ordinary source -PTY, and bulk; after one producer frame the writer re-runs selection. The -physical stream is still FIFO—V1 does not claim a second SSH channel—but the -finite burst and byte reserve bound head-of-line delay. Control overflow closes -an additional subscriber; overflow on the negotiated session owner is a -transport failure and reconnects that owner generation. - -Drain registration is one-shot per saturated epoch. `close`, `error`, -`attachClient`/`detachClient`, owner-generation replacement, and dispose -cancel every outstanding write callback and producer fence exactly once. -`setWrite` remains a test/compatibility seam; production reconnect ownership is -the socket/stdin construction plus `attachClient` and `detachClient`. - -In detached relay startup, immediately invalidate the synthetic stdout client -when `stdoutAlive` becomes false. A no-op writer must not look like successful -delivery. The first valid session-owner grant on an `attachClient` -socket/named-pipe client elects the owner; reconnect resume replaces its -generation atomically. Constructor identity and connection order confer no -role. - -One `DrainAwareStdoutWriter` owns every byte written to `process.stdout`, -including the initial relay sentinel, handshake residue, dispatcher frames, -and connect-mode forwarding. `runConnectMode` performs -`sentinel -> residue -> socket data` through that writer and pauses the source -socket after stdout saturation; it never mixes ad-hoc `stdout.write()` with -`sock.pipe(stdout)`. The same state contract wraps Unix sockets, Windows named -pipes, and the initial stdio client. - -Keepalive frames are independent of PTY credit, use reserved capacity, and have -the single-frame saturated-epoch exemption above. A decoder self-pause or -local writer-saturation epoch suspends dead-link evaluation. Resume calls the -same `rebaseHealthClocks(now)` used after a wake gap: set `lastReceivedAt` and -every existing `unackedTimestamps` entry to `now`, then allow a full timeout -window. Rebasing only received-data age is insufficient because the -outstanding-header-ACK conjunct would remain stale. During a suppressed -interval, keepalive intent coalesces behind one outstanding probe and the -header-ACK timestamp map has a hard entry cap; at 4095 entries it stops -ordinary main-to-relay admission and reserves the final coalesced entry for -cancel/liveness. -No pause fabricates an ACK. Tests sustain both states past 20 seconds and prove -zero reconnect oscillation or timestamp growth. - -## Main-process credit ownership - -`SshRelaySession.wireUpPtyEvents` remains the provider listener but stops -calling `runtime.onPtyData` and `webContents.send` itself. It validates the -provider generation/token and hands each notification once to a main-only -`SshPtyOutputDelivery` intake installed by `src/main/ipc/pty.ts`. This intake is -the only SSH owner allowed to ingest runtime output, mutate delivery state, or -send `pty:data`. - -### Main cumulative ledger - -The intake appends immutable wire spans: - -```ts -type PtySourceDeliveryIdentity = Readonly<{ - id: string - providerGeneration: number - clientGeneration: number - ownerGeneration: number - ptyIncarnation: string - deliveryToken: string -}> - -type PtySourceSpan = PtySourceDeliveryIdentity & - Readonly<{ - spanId: string - sourceStartSu: number - sourceEndSu: number - displayStart: number - displayEnd: number - data: string - splittable?: boolean - indivisible?: boolean - transform: { - transformed: boolean - rawLengthSu: number - scalarSafe: boolean - } - }> - -type SourceSpanRecord = { - span: PtySourceSpan - obligations: Map -} - -type SpanObligation = - | { state: 'open' } - | { state: 'transferring'; to: ConsumerId; reason: string } - | { state: 'settled'; reason: string } - | { state: 'transferred'; to: ConsumerId; reason: string } - | { state: 'canceled'; reason: string } - -type TokenAckPublication = { - obligationsTerminalEndSu: number - ackQueuedEndSu: number - ackPublishedEndSu: number -} - -type DesktopProjectionSpan = Readonly< - Omit & { - splittable: boolean - projectionSemanticsId: string - } -> -``` - -The ledger is separate from `PendingPtyData`. Queue merge, split, remainder, -drop sentinel, query salvage, thinning, and interactive bypass receive no -delivery token and cannot rewrite source spans. At SSH intake, -`SshPtyLegacyProjectionLedger` keeps per-PTY cursors and admits the complete -immutable `DesktopProjectionSpan`; it never receives only `data` plus source -length. -`PendingPtyData` continues to store display batching fields plus an opaque -projection admission ID, not mutable source accounting. - -`projectionSemanticsId` addresses an immutable per-admission record containing -the accepted chunk's ordered main-authoritative terminal facts and the -projection queue's before/after bounded scanner snapshots. This preserves -current main's dropped-output DEC mode 2031 subscribe/withdraw salvage without -putting mutable scanner state in the source ledger. A source gap resets the -recorded cross-chunk state before later bytes are admitted. - -When the data queue sends a display prefix, drops a pending entry, or replaces -it with salvage, it asks the range queue to consume the same operation. The -range queue—not mutable `rawLength` fields—returns the exact source length and -transform metadata for the renderer payload and consumer obligation. -Admission is transactional: - -1. reserve model bytes and create the source span; -2. stage the main terminal facts and before/after projection scanner snapshots; -3. reserve the exact desktop range by `spanId` and `projectionSemanticsId`; -4. enqueue display data and publish only after every reservation succeeds; -5. commit model ownership, main facts, and projection admission together. - -If model reservation fails, remove every uncommitted reservation. If -projection admission or `webContents.send` fails, roll back the uncommitted -range selection and restores the prior projection scanner snapshot without -publishing staged facts. After model commit, main facts remain published once -and a send failure atomically transfers the desktop obligation plus committed -projection state to a model-restore marker. Queue merge/split preserves the -ordered admission IDs, salvage/drop transfers exact superseded ranges and DEC -mode 2031 decisions, renderer reload transfers committed desktop obligations -before clearing, and token replacement rejects stale IDs by generation while -exact replacement coverage transfers their ranges. Untransformed source may -split only at a recorded display/source offset; a transformed range stays -indivisible. No rollback fabricates an ACK or destroys a live relay -obligation. Renderer ACK retirement reserves both range and ledger mutations, -validates both, then performs one no-throw commit; neither side becomes -terminal before that commit. - -Development assertions enforce: - -```text -receivedSu = openSu + transferringSu + settledSu + transferredSu + canceledSu -obligationsTerminalEndSu = - largest contiguous end whose required obligations are terminal -ackPublishedEndSu <= ackQueuedEndSu <= obligationsTerminalEndSu -``` - -Only `SshPtyOutputDelivery` may call the V1 cumulative ACK coalescer. The -generic `IPtyProvider.acknowledgeDataEvent(id, delta)` API remains for local -and daemon behavior. Legacy-fallback SSH may still emit its current delta, but -the relay ignores it and no legacy bound depends on it; it is a hard no-op for -negotiated V1 PTYs. At every shared `pty:ackData`, resync, heal, -write-off, drop, salvage, and reload call site, V1 routes renderer display -progress through -`SshPtyLegacyProjectionLedger`: parsing settles exact mapped source ranges and -heal/write-off atomically transfers them. These projection transitions may -advance ledger eligibility already earned by the model, but never emit legacy -`{ id, charCount }` wire traffic or manufacture source progress from a display -count. - -ACK eligibility and ACK publication are separate transitions. Terminal -obligations advance `obligationsTerminalEndSu` without waiting for a write -callback. The coalescer independently queues the latest cumulative eligible -end and advances `ackQueuedEndSu`. The mux write callback advances -`ackPublishedEndSu` and permits cleanup only on explicit success; it never -creates eligibility. A synchronous throw, callback error, or close leaves the -cumulative value queued for a generation-aware retry or reaches cancellation -proof on provider close. Coalescing replaces only with a greater cumulative -value, so retries cannot lose an eligible prefix. - -### Bounded asynchronous model admission - -The charged FIFO per PTY and global scheduler replace the unmetered -headless-emulator `writeChain` contract. `acceptPtyData` returns a Promise -receipt: - -1. before capturing the frame, reserve its charged retained bytes against the - per-PTY and global model-admission budgets; -2. the per-PTY budget covers one full token window and the global budget - matches the relay retained-data cap, so a conforming owner reaches token - backpressure before routine admission denial. If a transient frame still - cannot fit, keep that current decoded frame in a separately charged intake - slot and leave its model obligation open. Enter selective pressure mode: - quarantine at most 1 MiB or 64 later PTY data frames in wire order while - continuing to apply transport liveness, unrelated RPC control, and - cancellation proofs. Keep `pty.exit`, `pty.recoveryComplete`, activation - fences, and other source-ordering lifecycle frames behind all preceding - quarantined data for their token. A same-token cancellation proof may bypass - only by atomically canceling those quarantined obligations first. Do not - admit quarantined data out of order. If the reserve fills before capacity - returns, pause reads and start a 10-second provider-close deadline; -3. enqueue only after capacity is owned. Snapshot all consumer memberships and - allow bounded desktop/remote fan-out at that point; neither projection - progress nor queue ownership settles the required model obligation. - Preserve per-PTY order while allowing fair turns across PTYs; -4. resolve the receipt only from the emulator write callback. Then release the - queue charge, settle the model obligation, and advance eligible credit; -5. resume admission only after both low waters hold. Rejection cancels the - token and schedules restore; it never passes through the current - best-effort swallowed-error path. - -The relay writer rechecks control priority after every PTY frame, so the -receive reserve needs to cross only a bounded already-written PTY burst, not an -unbounded producer stream. If no control can be reached within the reserve and -deadline, provider close supplies generation cleanup proof. Selective pressure -never settles, drops, or reorders a data frame and never lets a model stall -silence cancellation indefinitely. - -Provider close, token supersession, PTY exit, and runtime disposal cancel -queued-but-unstarted entries and reject their receipts exactly once. An -in-flight emulator callback owns its entry until completion or failure and -must pass its captured token/generation check before committing. Reconnect and -supersession use the migration fence above rather than letting that callback -race a replacement checkpoint. Failure dispatch consults the exact -`(providerGeneration, ptyId)` migration owner before invoking generation close; -this does not suppress the ordinary non-migrating failure policy. The old -Promise chain may remain as the per-PTY execution primitive only after each -link is charged by this scheduler; it is no longer an unbounded owner. - -### Desktop, mobile, web, and agent policy - -Consumer membership is snapshotted when each span arrives: - -- The main terminal model is always required. - `runtime.acceptPtyDataBounded` returns the asynchronous receipt Promise - above; it resolves only after the emulator accepts the span. - Status and agent-session observers derived from that model add no duplicate - obligation. -- The desktop renderer is a recoverable projection. Parsing settles its - obligation. Hidden thinning, reload, destroyed-window, send failure, - pending-cap replacement, or delivery heal atomically transfers the - obligation to the already-accepted main model and emits a model-restore - marker before settlement. A transfer requested before the model receipt - remains pending and commits only when that receipt succeeds. Once the model - receipt exists, desktop obligations - remain tracked for main-to-renderer bounds but are not required for upstream - ACK eligibility. -- A mobile/web/raw agent terminal subscriber that negotiated lossless ACKs is - required while attached and settles independently from its bounded delivery - cursor. At its ACK cap it stops sending and remains required; a stall cannot - auto-transfer itself out of upstream backpressure. On explicit detach or - replacement, transfer to a snapshot/resubscribe marker if supported; - otherwise cancel that consumer and close only its stream. -- A legacy or observational remote subscriber is best-effort and creates no - upstream obligation. It receives bounded fan-out and is dropped/resynced on - overflow. - -Current mobile notification replay remains a separate runtime method and -identity space. Its notification epoch and post-local-delivery watermark prove -notification catch-up only; terminal obligations require the stream generation -and immutable encoded-byte/source-range mapping below. - -The token ACK advances when the main model and every currently required -lossless consumer for the contiguous prefix have terminal obligations. A -desktop stall therefore cannot freeze a healthy mobile/web consumer, while an -actually lossless remote subscriber still participates explicitly. - -Each lossless remote stream owns an immutable encoded-byte/source-range ledger: - -```ts -type LosslessRemoteSendRange = { - streamGeneration: string - encodedStartByte: number - encodedEndByte: number - providerGeneration: number - ptyIncarnation: string - deliveryToken: string - sourceRanges: ReadonlyArray<{ - spanId: string - sourceStartSu: number - sourceEndSu: number - indivisible: boolean - }> -} -``` - -Existing `terminal.multiplex` `ackOutput: 1` remains a byte-delta flow-control -mechanism and creates no SSH source obligation. A required source-mapped stream -must separately negotiate `ackOutputSourceRanges: 1`. The server allocates an -opaque `streamGeneration` in the subscribed control frame; every cumulative -ACK carries that generation and `ackedEndByte`. A reused `streamId`, old -client, legacy `{bytes}` ACK, or stale generation cannot settle the new stream. - -The mapping is recorded only when the remote writer accepts that exact encoded -output payload, in the same byte unit used by its ACK window. Batching flushes -on provider generation, PTY incarnation, or delivery-token change. When one -encoded frame contains multiple same-identity source spans, it records their -ordered composite list rather than collapsing them into a proportional range. -An ACK must be a finite safe integer in -`previousAckedEndByte <= ackedEndByte <= lastAcceptedByte`; excessive values -are rejected and counted, never clamped into full settlement. An in-range -partial-frame ACK advances the byte watermark and releases exactly that byte -budget, but retains the covering frame's immutable source mapping and settles -no source units. Only complete recorded frame boundaries settle their exact -ordered source ranges. UTF-8 width, JSON escaping, `rawLength`, and display -transforms are never converted proportionally. - -The same attached stream may cross a source-token rotation without transferring -its older unsettled frame. Admission requires the same PTY ID, provider -generation, and incarnation; strictly greater client and owner generations; a -different delivery token; and exact source/display continuity. The ledger then -rebinds future frames to the new identity while older frames retain their own -immutable identity and settle at their encoded boundaries. Equal, lower, -partially advanced, cross-provider, cross-incarnation, or same-token rotations -are rejected. Before stream replacement, snapshot recovery, or detach, create -the replacement owner and atomically transfer every remaining mapping; -otherwise cancel that consumer and its bounded stream. Old stream generations -cannot settle new mappings. - -The main registry stores the immutable source identity with each admitted -remote mapping, not only its `spanId`. A replacement reservation moves the -named consumer obligations to `transferring`; only an accepted headed or -headless `SnapshotEnd` publication at or beyond the reservation's required -sequence commits them. Stale generation, failed publication, disconnect, or -explicit rollback restores the original live-stream obligation. If -token-scoped cancellation proof has already reclaimed the authoritative span, -late ACK/settle prunes the cached mapping, detach skips absent spans, and a -replacement commit returns false without dereferencing the reclaimed record. -Rollback then deletes the exact reservation and skips already-absent spans. -These paths are idempotent and create no credit. - -ACK-pending output overflow uses the same transaction. For a source-mapped -stream, serialize the bounded snapshot, reserve only immutable spans whose -model-sequence end is covered by its `seq` through -`reserveRemoteTerminalSourceRangeReplacement`, publish every snapshot frame, -then call `commitRemoteTerminalSourceRangeReplacement` against the exact -current stream generation, snapshot source identity, and sequence. Only after -commit may the server trim queued chunks with -`chunk.seq <= snapshot.seq` and clear the overflow marker. Serialization, -publication, or commit failure calls -`rollbackRemoteTerminalSourceRangeReplacement`, preserves the live -obligations, reports the stream error, and detaches that stream. One -`ackRecoverySnapshotInFlight` flag bounds the operation to single-flight. -At the encoded-byte ledger, snapshot replacement commit is itself idempotent: -duplicate commits and commits after close are no-ops, preserve cumulative byte -coordinates, and remove only source mappings covered by the authoritative -snapshot sequence. - -The stall policy is deliberately split. Desktop-only parse failure reaches its -bounded projection cap, transfers to model restore, and lets upstream credit -continue. A stalled model receipt or attached lossless remote has no automatic -projection transfer: its required obligation stays open, the token window -exhausts, and the relay pauses the native PTY when every remaining delivery is -blocked. Only an explicit, capability-proven snapshot/resubscribe transition -can transfer a lossless remote obligation. - -### Exactly-once lifecycle - -`settle`, `beginTransfer`, and `cancel` are compare-and-set operations from -`open` for both the upstream token span and each consumer obligation. -`transferring` becomes `transferred` only after the named replacement fence or -becomes `canceled` on mismatch/failure; duplicates are no-ops with diagnostics. -Required obligations becoming terminal advances -`obligationsTerminalEndSu`. That transition makes the cumulative ACK eligible; -it does not wait for ACK publication. The coalescer advances `ackQueuedEndSu`, -and only the later mux write callback advances `ackPublishedEndSu` and allows -record reclamation. A token span begins transfer only when the relay atomically -moves reconnect-grace ownership to a new token and the attach response -declares the new cumulative boundary, or cancels after -explicit/connection-close proof. The transaction creates the replacement -owner before marking source `transferring`; only exact recovery-complete -coverage terminally transfers it. - -| Event | Mandatory transition | -| ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -| spawn/attach response decoded | install provisional `sourceActivation` in synchronous `beforeResolve`;

keep at most one admitted completion attempt | -| stale/overlapping recovery attempt | cancel only that attempt's token; never mutate the replacement mux, checkpoint, PTY ownership, physical process, or owner lease | -| current recovery cancellation publication/proof fails | after quarantine ownership transfer, close the exact provider generation and release its mux, provider, publishers, and registration once; retain physical PTY ownership for reconnect | -| partial remote cumulative byte ACK | advance/release exact byte credit; retain the covering source frame and obligation until a complete recorded boundary | -| contiguous higher-generation source token | keep the stream attached, bind later frames to the new identity, and preserve unsettled older-token frame mappings | -| remote snapshot replacement | reserve immutable span IDs/ranges, commit only after current-generation `SnapshotEnd` coverage, otherwise roll back | -| snapshot commit after proof reclaimed a span | reject commit without dereference;

Desktop/remote fan-out may begin after -the admission budget owns the frame, but the model obligation settles only -after the emulator callback. Admission wait leaves it open and pauses reads at -the charged limit; rejection triggers token cancel rather than acknowledging -data the model did not own. Renderer progress is always display-side input to -the range queue and is never interpreted directly as source units. - -## Incremental frame decoding - -The actual main transport contract is extended as follows: - -```ts -type MultiplexerTransport = { - write(data: Buffer, onSettled: (result: SinkWriteSettlement) => void): SinkWriteResult - writableLength(): number - writableHighWaterMark(): number - onWriteDrain(cb: () => void): () => void - onData(cb: (data: Buffer) => void): () => void - onClose(cb: () => void): () => void - pauseReads(): void - resumeReads(): void - close(): void -} -``` - -`waitForSentinel` constructs these hooks from the real `ClientChannel`: -`channel.stdin.write(buf, callback)`, writable length/high-water mark, and -`on('drain')` for output, plus -`channel.pause()/resume()` for relay stdout. This covers ssh2 and -`SystemSshCommandChannel`, whose stdout-facing channel implements the same -Readable contract. WSL child stdin/stdout exposes the same metrics, -callback/drain, and pause/resume adapter. The startup residue is delivered once -before later data. - -`SshChannelMultiplexer` also owns one main-to-relay writer with exactly three -bounded FIFO lanes: - -1. `liveness` for the coalesced probe, including the one saturated-epoch - bypass; -2. `control` for source ACK, cancellation, exit, RPC request, and response - frames; -3. `ordinary` for `pty.data`, including PTY input/paste traffic. - -The scheduler rechecks priority after every frame and whenever drain reopens -the writer. Liveness wins first. Control wins over queued ordinary traffic -until four control frames have been selected while ordinary remains queued; -the next selection must be one ordinary frame and resets the counter. FIFO is -preserved within each lane. All non-bypass writes still wait for their -per-write callback and `onWriteDrain` after saturation. Producer-side bulk -shaping and fixed filesystem-frame admission remain with their existing -owners; they do not create a fourth mux-writer lane. Thus control cannot remain -behind an old ordinary backlog after drain, ordinary input cannot starve under -a sustained control stream, and V1 ACK settlement has a concrete write fence. - -On the relay, the initial client uses `process.stdin.pause()/resume()` and each -accepted Unix-socket/named-pipe client uses `socket.pause()/resume()`. -`attachClient` accepts those hooks; `detachClient` releases them. Handshake -decoders retain synchronous first-frame behavior and transfer both exact -residue and pause ownership to the dispatcher. - -Both protocol copies then use this state machine: - -1. `feed()` appends buffer views without copying and charges bytes. -2. Drain at most 64 frames or 4 ms. -3. If another complete frame remains, acquire one idempotent decoder pause - epoch and continue with `setImmediate`. -4. Release the pause only when complete-frame backlog and queued bytes fall - below low water. -5. `reset`, handshake `drain`, transport close, and dispose cancel the - continuation and release exactly the epoch they own. - -Main model-pressure mode is the one bounded exception to immediate read pause. -It may classify complete frames into the charged 1 MiB/64-frame data -quarantine while dispatching only eligible control/liveness frames, then -either drains data and token-ordering fences in original order or closes the -provider at the deadline. Exit, recovery completion, and activation cannot -overtake a preceding quarantined frame for the same token. It does not scan -past an incomplete or oversized frame and cannot expand the ordinary decoder -input cap. - -Handshake consumers require the first complete frame synchronously. Preserve -that behavior, then yield before later frames. `drain()` must cancel a scheduled -continuation and return all unread handshake residue in exact byte order so the -next consumer receives it once. - -The decoder permits one advertised valid 16 MiB frame plus 1 MiB input slack. -A partial valid frame keeps reads enabled until that cap; exceeding it closes -the offending transport rather than retaining back-to-back maximum frames. -Oversized payloads are discarded incrementally without full retention. -Sender-side finite PTY bursts and the reserved control lane bound how far a -keepalive/control frame can sit behind PTY data. While paused by this decoder, -the mux suspends both dead-link conjuncts. Resume rebases `lastReceivedAt` and -all outstanding header-ACK timestamps exactly like the existing wake-gap -handler; outgoing keepalives still run. - -In `SshChannelMultiplexer.handleFrame`, clamp header `ack` to -`nextOutgoingSeq - 1` and delete only keys already present in -`unackedTimestamps`. Never iterate a dense integer range toward an untrusted -32-bit value. This remains independent from PTY credit. - -## Cleanup and reconnect - -Every dispatcher client has a generation, and the negotiated session owner has -a separate transferable owner generation. Socket close/error, -`attachClient`/`detachClient`, and dispose invalidate or advance the client -generation atomically. Unexpected disconnect retains the owner generation and -lease through grace; only a proved replacement increments it, and grace expiry -invalidates the lease so a later election starts a new generation.

It retains at most -512 Ki su and 2 MiB charged bytes per PTY; reaching either cap pauses that PTY -instead of dropping more output. A valid owner resume atomically installs the -new owner generation, transfers each cursor to a new token, and returns only -activation and recovery-range metadata. Source-ranged `pty.data` then drains -before the completion fence and live activation. Expiry invalidates the owner -lease, -emits `pty.deliveryCanceled` when possible, releases the gap, resumes the PTY, -and records restore-required/data-gap telemetry. Ordinary subscriber loss or -no-subscriber state outside owner grace retains only the existing replay tail. - -`SshRelaySession.reattachKnownPtys` waits for session-grant readiness and each -PTY's model-migration fence, then runs at most eight attaches concurrently. -Each PTY has its own 10-second attempt deadline and `try/catch`; one failure -cannot abort later PTYs. `notFound` and identity mismatch keep their existing -stale-lease behavior. Other errors are recorded, retried once with bounded -jitter while the same reconnect attempt is current, then surfaced per PTY -without tearing down successful siblings. Time-to-last-reattach is therefore -bounded by waves rather than `N × RTT`. - -Reconnect and replay always create new tokens even when IDs are reused. Old -ACKs and callbacks fail generation/token checks. The attach response declares -the exact checkpoint and recovery end; ordinary source-bearing `pty.data` -proves the gap and the completion fence establishes the live boundary, so main -never double-ingests old obligations. Replace -`SshRelaySession.forwardReattachReplay` with this tokenized intake and delete -`RECONNECT_REPLAY_DUPLICATE_WINDOW_MS`/`shouldForwardReattachReplay`: a -wall-clock fingerprint can suppress legitimate identical output, while the -source checkpoint is authoritative. Exit before reattach may still synthesize -`code: -1` after `notFound`; retaining remote exit tombstones is a separate -behavior change and is not required for the memory bound. - -Recovery receipt is transactional. Main retains quarantined recovery `pty.data`, -the candidate mux, token, checkpoint, and `recoveryEndSu` until the exact -completion fence validates. It commits no partial body to the model. On -failure it requests cancellation only through the candidate mux and accepts -only matching proof; a stale attempt may not touch current mux state. A -quarantine-only attempt may not yet have a main-intake token identity, so -`SshRelaySession` first requires `canceled: true`, finite safe cumulative -ends, `creditedEndSu` equal to the recovery checkpoint, and `sentEndSu` -covering the highest exact-token source range observed privately. Only then is -the intake's no-identity application an intentional no-op; malformed, -under-covering, or checkpoint-mismatched proof fails closed. A -current attempt whose cancellation publication or proof rejects closes the -exact provider generation and its registered resources once, rather than -leaving ambiguous authority. After a successful empty recovery it keeps -`recoveryEndSu` as a live continuity anchor until the first live frame arrives. -A proved recovery failure marks the existing PTY lease detached and retryable -rather than deleting ownership or terminating the physical process. - -For an operation-ID spawn replay, physical result lookup completes first; the -current request then creates and fences a new subscription as specified above. -Disconnect after physical commit/before response leaves the PTY retained but -no stale token. - -PTY shutdown and natural exit cancel native pause state before disposing -node-pty. Natural exit may still leave a charged sealed-unsettled delivery -record; only its native process is gone. Relay disposal generation-closes those -records and clears scheduler/exit timers before walking PTYs. A folder -workspace removal follows the same PTY teardown path; no design step assumes a -Git worktree. - -### SSH producer-pause intent - -Negotiated V1 implements `SshPtyProvider.pauseProducer` and `resumeProducer` -with a token/generation-scoped `pty.setDeliveryPaused` request; window size is -not renegotiated to zero. Relay marks that owner delivery ineligible and pauses -the native PTY only when all required deliveries are ineligible, while another -healthy subscriber may continue. Resume restores eligibility under the -original window. `setPtyBackgrounded` is a separate token-scoped scheduling -hint; it does not itself drop source data or silently convert a lossless model -obligation into keep-tail behavior. - -For V1, desktop pending-cap pressure transfers the recoverable projection and -does not call producer pause.

Cap per-client and aggregate - publication bytes.

A macOS client can attach to a native ConPTY owned by a paired Windows runtime, so -renderer-side local/SSH/remote heuristics can transfer OSC 10/11 authority to the wrong responder. - -The PTY-owning process now classifies the backend from its own platform and the shell that actually -won spawn: `windows-conpty`, `windows-wsl`, or `posix-pty`. Native ConPTY consumes complete OSC 10/11 -queries before model, replay, or view delivery. During the bounded startup window it replies once -when validated theme colors are available; after the deadline, or without colors, it consumes the -query without replying. A consuming-view handshake does not transfer this authority. Split query -candidates remain bounded and private across authority-close, expiry, and snapshot barriers; a -candidate that proves malformed is released unchanged. - -WSL and POSIX PTYs continue to transfer authority to the normal visible/hidden responder after the -startup window. The same owner-side rule applies to local, daemon, SSH-relay, and paired-runtime -PTYs. This amendment supersedes contrary transfer/fallback language below; the echo projection is -selected only by the authoritative owner backend, never by renderer or connection metadata. - -## Problem - -On native Windows ConPTY sessions, a new agent can sometimes show terminal protocol bytes as user -text: - -```text -]10;rgb:2e2e/3434/3434\]11;rgb:ffff/ffff/ffff\ -``` - -An independent symptom can prefix user input with `[I`, the printable tail of the standard terminal -focus-in report `CSI I`. - -The OSC text is an Orca-generated reply to the agent's OSC 10/11 foreground/background query. The -agent can issue that query before a daemon-backed `spawn()` resolves to the renderer, and waits only -about 100 ms for the answer. Orca therefore has a short-lived main-side startup responder in -addition to the normal renderer/model query authorities. On affected ConPTY timing, the reply sent -to the PTY is returned as cooked output with its ESC bytes removed. The current ingestion order -records that cooked echo in the authoritative runtime model before any renderer-bound filtering. - -The focus symptom must not be treated as the same bug without evidence. ConPTY deliberately emits -DECSET 1004 (focus reporting) and DECSET 9001 (Win32 input mode) at startup. A direct native -PowerShell ConPTY capture consistently produced the bootstrap pair, while an injected `CSI I` was -consumed as a focus event and did not render as `[I`. The bootstrap is valid transport protocol; -the failure requires an additional agent, timing, input-mode, or replay condition. - -## Root Cause - -OSC responders downstream of the PTY owner do not know whether the bytes came from native ConPTY, -WSL, or a POSIX PTY. `LocalPtyProvider` calls the runtime before its public data listeners -([`local-pty-provider.ts`](../../../src/main/providers/local-pty-provider.ts)), while daemon `Session` -advances sequence state, writes its emulator, persists pending output, and fans out data before -Electron main receives it ([`session.ts`](../../../src/main/daemon/session.ts)). A renderer-only -filter can therefore misclassify paired runtimes and hide the symptom without removing it from the -authoritative model, daemon history, snapshots, or remote delivery. - -The corrupted echo is timing-dependent but its ordering failure is deterministic: any sanitizer -downstream of an authoritative consumer is too late. The independent `[I` symptom has not yet met -that evidentiary bar, so this design fixes the proven OSC path and adds the real focus-path harness -without pre-approving a speculative focus workaround. - -## Data Flow - -```text -node-pty / remote relay PTY - -> shell-ready marker scan - -> source-owned serialized ingress transaction - -> consume an early OSC query and write one canonical reply - -> match or losslessly release the measured native-Windows echo projection - -> authoritative emulator + persistence/history - -> runtime side effects and mobile/remote stream - -> renderer delivery or hidden-drop decision - -> live terminal / snapshot restore -``` - -Raw sequence spans travel beside cleaned strings through every downstream hop. Empty transformed -spans advance sequence and flow-control state without writing bytes into an emulator or view. - -## Rejected Prototype - -The current working-tree prototype is not the implementation of this design: - -- It removes ConPTY's leading `?1004h` in the renderer. This changes valid native-console focus - semantics for every Windows PTY, including programs unrelated to agents. -- It filters OSC echo text only after runtime/model ingestion. The live pane can look clean while a - hidden restore, reconnect, mobile view, or CLI snapshot still contains the garbage. -- Its echo state activates only after both color slots are answered. An echo of the first response - can escape if it arrives before the second query. -- Its partial-match buffer can be lost on timeout, and its substring search can remove a later - legitimate string that happens to equal a reply. - -Implementation starts by removing the prototype's bootstrap output filter and renderer-only cooked -echo filtering. Existing unrelated Windows focus-idle safeguards remain. - -## Existing Contracts Preserved - -This design extends, rather than replaces: - -- [`terminal-model-view-contract.md`](../terminal-model-view-contract.md), especially singular query - authority, authoritative model restore, and raw sequence ordering; -- [`terminal-query-authority.md`](../terminal-query-authority.md), especially delivered-versus- - hidden-dropped ownership and replay silence; -- [`terminal-side-effect-authority.md`](../terminal-side-effect-authority.md), especially parsing PTY - bytes once in main before renderer delivery. - -The startup responder is a bounded exception needed before normal delivered/dropped ownership can be -established. It must join the same ingestion decision, not operate as an unrelated renderer scrub. - -## Decision 1: Source-Owned PTY Ingress Transaction - -Sanitization must run on the host that owns the PTY, before that host mutates any authoritative -model or persistence. Electron main is too late for daemon sessions: `Session` has already advanced -its sequence, written its emulator, recorded pending output, and broadcast the data before main's -provider callback runs. - -The transaction therefore has three installations of the same shared state machine: - -- in `LocalPtyProvider`, before its configured runtime callback and data listeners; -- in daemon `Session`, before `outputSequence`, emulator writes, pending/checkpoint records, and - attached-client fanout; -- in relay `PtyHandler`, before relay replay/history buffering and `pty.data` fanout. Main's - `SshPtyProvider` is only an RPC proxy and never sanitizes relay output. - -Electron main receives already-classified daemon data. A remote-runtime desktop client does not -reinterpret the stream; the remote Orca host owns its transaction. WSL sessions follow their actual -provider owner but never enable the native-Windows compatibility projection. - -Fresh-session creation carries startup-transaction intent atomically. Daemon `createOrAttach` -receives the recognized-agent intent, execution-host kind, deadline, and validated renderer-pushed -color attributes. It first decides fresh versus reattach; only a fresh result constructs the -transaction before releasing the subprocess's already-buffered early output. A reattach discards -the intent without arming state. Cancellation, spawn failure, and teardown clear intent before any -PTY id can be reused. - -Local creation installs the transaction before subscribing to node-pty output. Relay `pty.spawn` -carries the same fresh-session intent and installs it before releasing relay PTY output; relay -`pty.attach` never accepts it. If any owner cannot establish this ordering, the early responder is -not armed and normal query authority handles the query. - -Increment `DAEMON_PROTOCOL_VERSION` for the new create/wire shape and add a named numeric-threshold -predicate in the daemon adapter/router. Current exact-version hello behavior remains; supported -legacy versions route through their existing adapters and fail the predicate. The SSH relay gets a -separate versioned spawn/data capability because daemon protocol support says nothing about relay -support. - -An old daemon or relay keeps the legacy behavior and is never treated as having sanitized snapshots -or history. Main must not apply a second best-effort scrub to legacy output. New sessions receive -the invariant only after the owning daemon/relay is upgraded or restarted; an already-attached -legacy session remains explicitly outside it. - -### Composition with shell-ready preprocessing - -The ingress sequence domain begins after the existing shell-ready scanner. That scanner may hold -transport bytes and removes its private ready marker; marker bytes have never belonged to terminal -model or delivery sequence space and continue not to count. Its released non-marker bytes enter the -new ingress transaction in original order. - -Snapshot and teardown barriers drain in pipeline order: the shell-ready scanner first releases its -non-marker buffer, then the ingress transaction resolves or abandons its candidate, then the model, -persistence, and views observe the resulting emissions. No later stage may introduce an unmetered -string transform. - -### Raw sequence and emission contract - -The state machine accepts source chunks with an explicit raw half-open range and returns zero or -more ordered emissions: - -```ts -type PtyIngressSourceChunk = { - data: string - rawStartSeq: number - rawEndSeq: number -} - -type PtyIngressEmission = { - data: string - rawStartSeq: number - rawEndSeq: number - transformed: boolean -} -``` - -The raw range is the post-shell-ready ingress sequence domain and remains contiguous even when -`data` is shorter after sanitization. The ordered emissions partition accepted source ranges without -overlap. Producer flow-control acknowledgement follows those emitted raw spans and is counted once -from `rawEndSeq - rawStartSeq`, never from emitted string length. A held prefix delays its ACK; the -buffer is strictly bounded and the serialized queue cannot acknowledge later output ahead of it. - -The ingress raw high-water advances when a source chunk is accepted. Model-applied and -view-delivered high-waters advance only through ordered emissions, including empty transformed -emissions that consume a raw range. Runtime/mobile listener metadata carries -`rawLength = rawEndSeq - rawStartSeq`, not `data.length`. A restore that overlaps a transformed span -cannot slice cleaned text by raw offset and must request a fresh authoritative snapshot, matching -the existing `rawLength !== data.length` safety rule. - -This metadata is end-to-end, not local to the state machine. Implementation changes the complete -path: - -1. daemon `Session` or relay `PtyHandler` emission callback; -2. daemon/relay batching, coalescing, splitting, and wire notification; -3. daemon adapter or `SshPtyProvider` decode; -4. `OrcaRuntimeService` model and runtime/mobile listeners; -5. main renderer batching, pending/drop accounting, and preload payload; -6. renderer reconciliation and remote-runtime binary/live frame decoding. - -The wire representation carries `data`, `seq = rawEndSeq`, `rawLength`, and `transformed`. A -span-only emission has empty `data` but non-zero `rawLength`; no layer may drop it before advancing -its high-water and producer ACK. It is not written to an emulator or xterm. Coalescing is permitted -only for contiguous spans and sums raw lengths independently of string lengths. A transformed -emission is indivisible because there is no byte-for-byte raw-to-clean offset; splitters must flush -it as its own frame or request snapshot reconciliation instead of slicing it. - -If a snapshot is requested while a partial candidate is held, the transaction first abandons that -candidate and releases its bytes unchanged as an ordered emission. The authoritative emulator and -snapshot sequence therefore describe the same raw high-water. - -### Serialization and teardown - -Each PTY has a non-reentrant serialized ingress queue. A provider write may synchronously produce a -nested callback, but that callback is appended after the current source chunk rather than delivered -ahead of its remaining bytes. Timeout releases and snapshot barriers enter the same queue. - -On exit, the queue releases all buffered bytes, applies those emissions to the authoritative model -and persistence, and fans them out before `onPtyExit`, `pty:exit`, or PTY state cleanup. Relay -disposal must flush both ingress prefixes and its existing pending output batches before clearing -them or killing PTYs, matching the natural-exit flush-before-`pty.exit` order. No drain may recreate -state after teardown. Ordinary chunks pass through as one unchanged emission. - -## Decision 2: Startup OSC Queries Are Consumed Authoritatively - -The early OSC 10/11 responder remains because removing it would regress daemon-hosted agent startup -and the agent's short color-query timeout. Its implementation moves into the source-owned ingress -transaction. - -When registered for an agent spawn, it: - -1. recognizes exact OSC 10/11 query grammar across provider chunks; -2. builds replies from validated renderer-pushed foreground/background attributes; -3. emits the canonical ST-terminated, 16-bit-channel reply used by renderer/model query authority, - regardless of whether the query ended with BEL or ST; -4. records each reply transaction before writing it to the provider; -5. consumes the answered query from the authoritative model and view emissions so neither the - hidden model nor a delivered renderer can answer it a second time; -6. begins echo recognition as soon as each individual reply is written. - -If attributes or a provider are unavailable, native ConPTY consumes the query without replying; -WSL and POSIX PTYs pass it through unchanged to normal query authority. A reattach never registers -startup response state, matching current behavior, but native ConPTY ownership still prevents a -downstream reply. - -### Exact authority transfer - -Startup query response authority opens only for a fresh session whose atomic creation installed the -transaction before buffered output release. For WSL and POSIX PTYs it closes at the first of: - -- both OSC 10 and OSC 11 slots have been answered; -- the startup deadline expires; -- main sends an ordered authority-close control after either the consuming-view handshake or the - hidden-runtime ownership mark is established; -- the spawn fails, is cancelled, reattaches, or exits. - -Native ConPTY does not transfer OSC 10/11 authority at those boundaries: the deadline stops source -replies, while complete queries remain consumed for the life of the PTY. Closing response authority -does not discard already-written reply candidates. Echo recognition has -its own bounded lifetime and may finish or drain after normal authority takes over. A close and a -provider callback are ordered by the source owner's per-PTY ingress queue. Transport attachment to -a daemon/relay client is not a consuming-view signal. Main sends the close over a versioned control -method, and the source owner acknowledges the applied ingress sequence. Queries before that ordered -boundary are either consumed at source or removed from emissions; queries after it pass unchanged -to the normal delivered/hidden decision. Each query therefore belongs to exactly one authority. - -The regular authority rules continue after the bounded startup window: - -- delivered live bytes are answered by the live view; -- hidden-dropped live bytes are answered by the runtime model; -- replayed, seeded, and snapshot bytes are answered by nobody; -- the daemon's persistence emulator never writes replies. - -Implementation must amend `terminal-model-view-contract.md` and `terminal-query-authority.md` to -name this source-owner startup authority, its opening/closing events, and its no-replay rule. It is a -real third responder class, not an undocumented exception. - -## Decision 3: Matched Echo Suppression Is Lossless and Pre-Model - -Only native Windows ConPTY agent spawns that pass the deterministic provider harness enable a -compatibility projection for replies written by the startup transaction. WSL and POSIX SSH PTYs do -not. A remote-runtime PTY can enable it only on its owning Windows host under the same evidence and -capability gate. - -The harness records the exact projection ConPTY returns for the canonical ST reply, including its -chunking and any console transformation. The implementation must not assume that the projection is -always merely "remove ESC", and BEL or other reply forms are not added without separate evidence. -For every written reply, the transaction records that exact expected projection. Recognition is: - -- FIFO in reply-write order; -- anchored at the next possible output position, not an unbounded substring search; -- active immediately for each reply instead of waiting for both color slots; -- bounded by the startup deadline and maximum reply length; -- streaming across chunk boundaries. - -If incoming bytes diverge from the expected projection, all buffered bytes are released unchanged -and that candidate is abandoned. If the deadline expires or the PTY is cleared while a prefix is -buffered, the prefix is released through the serialized ingestion queue; it is never discarded. A -match advances the raw span but emits no bytes to the model, persistence, or views. - -Projection matching cannot prove provenance. An application can print the same projected text at -the candidate position, causing a false-positive removal while the later real echo remains visible. -This is the central drawback of the workaround. It is accepted only if the real provider harness -shows a stable, immediate projection inside the narrow registered-agent startup window; otherwise -Orca disables the projection and keeps the visible output rather than risking deletion. - -When the projection is enabled, the exact-collision behavior is explicit: the first identical -anchored candidate is removed and a later real echo is allowed through. The test fixture must assert -that result. This accepts a narrowly bounded false-positive risk instead of pretending provenance -is knowable; the release gate must document the observed timing window and justify that tradeoff. -Unknown, delayed, or interleaved transformations pass through visibly. - -## Decision 4: Preserve ConPTY Focus Protocol - -Orca must deliver the ConPTY bootstrap `?1004h`/`?9001h` to live terminal emulators unchanged. It -must not remove, reorder, or fabricate transport bootstrap modes. - -The `[I` investigation gets a deterministic harness before a behavior change. The harness must -exercise the actual renderer focus callback and provider write path, not only inject `CSI I` -directly into node-pty. It records: - -- raw provider output and its order; -- whether the focus report came from live ConPTY bootstrap state, an application-owned DECSET 1004, - or replayed snapshot state; -- the exact bytes written to the provider; -- the exact bytes returned by the provider and stored in the model; -- agent lifecycle state when the report was emitted. - -The implementation gate is strict: - -- If stale snapshot modes cause the report, fix snapshot rehydration. Transport bootstrap focus mode - is not persisted as application ownership. -- If a live agent receives transport focus before it owns terminal focus reporting, record that - evidence without shipping a suppression heuristic from this document. -- If provider input/output transformation corrupts a correctly owned focus report, fix or sanitize - that transformation at the same pre-model ingress boundary used for OSC replies. - -No global `?1004h` filter ships under any outcome. - -If the harness proves a focus-ownership race, a follow-up design is required before implementation. -That design must define the output-to-input ownership signal, distinguish xterm focus events from -identical typed/pasted/programmatic bytes, specify startup transitions and deadlines, define any -snapshot/wire metadata, and cover the separate explicit reattach-focus write path. This document -does not pre-approve an ownership state machine whose input provenance cannot yet be represented. - -## Snapshot and Replay Rules - -Interactive modes in a snapshot are capabilities of the live application, not proof that a new -view should emit input immediately. - -- Cold restore into a fresh shell keeps the existing full mode reset. -- Reattach to a live agent may rehydrate application-owned focus mode, but never transport-only - bootstrap ownership. -- Snapshot serialization/replay must not mutate live ownership trackers. -- A snapshot containing an OSC query or an old Orca reply never produces a provider write. -- Model and renderer snapshots must both be free of matched cooked reply projections. - -Any future focus ownership metadata must be explicit; it cannot be inferred from serialized -`?1004h` text. - -## Failure Policy - -Safety is asymmetric: - -- This design does not intentionally suppress a focus notification; evidence of a focus-ownership - race triggers a follow-up design instead. -- Passing through an unrecognized OSC echo is safer than deleting output that may belong to the - application. -- Missing a startup color reply falls back to the existing renderer/model authority. Duplicate - replies are forbidden. -- Losing buffered output on timeout or teardown is forbidden. - -## Cross-Platform and Remote Scope - -- Native Windows local and daemon ConPTY: startup response plus evidence-gated echo compatibility - path; focus investigation only until a proven root cause has its own complete design. -- WSL: normal Linux terminal semantics; no ConPTY echo or focus workaround. -- SSH: the same ingress/query ownership ordering, but no native Windows echo projection unless the - remote host protocol later supplies explicit equivalent evidence. -- Remote runtime: the remote Orca host owns ingestion and must implement the same contract there; - desktop local main does not reinterpret its stream. -- Mobile/web views: consume the sanitized authoritative model stream and retain exactly-one query - response authority through the existing terminal-driver election. - -## Edge Cases - -- A query or echo split at any byte boundary, including OSC ST split across chunks. -- The first reply echo arriving before the second color query. -- Unrelated output, an exact application-text collision, or a partial match before the real echo. -- Timeout, snapshot, detach, process exit, daemon shutdown, or relay disposal while bytes are held. -- A provider write causing a synchronous nested output callback. -- Fresh spawn versus reattach, cancellation, PTY-id reuse, and an authority-close control racing - with output. -- BEL-terminated queries still receiving the canonical ST reply. -- Empty transformed spans crossing coalescing, splitting, ACK, mobile, and remote-runtime layers. -- Old daemon/relay protocol versions and sessions that survive an application upgrade. -- WSL or POSIX SSH running from a Windows desktop without inheriting local ConPTY workarounds. -- Focus gained through normal terminal input versus the separate explicit reattach-focus write path. - -## Test Plan - -### Deterministic provider harness - -- Capture the native ConPTY bootstrap across natural and forced chunk boundaries. -- Reproduce the OSC reply echo with the real provider and an agent query fixture. -- Exercise BEL and ST queries and assert the same canonical ST reply, plus separate OSC 10/11 - queries and combined OSC 10 `?;?`. -- Force the first reply echo before the second query. -- Split every byte boundary in query and echo fixtures. -- Print the expected projection immediately before the real echo and assert that the first - identical candidate is removed while the later echo passes through. -- Exercise focus gain/loss through the actual xterm focus path. - -### Ingress integration - -- Assert local runtime ingestion and daemon emulator/pending/checkpoint persistence receive - classified data before storing it. -- Assert renderer and mobile delivery receive the same visible output. -- Assert raw start/end spans advance by original provider length, producer ACK contribution is - counted exactly once, and mobile/runtime metadata reports the raw span rather than string length. -- Assert a partial candidate is released unchanged on mismatch, timeout, snapshot barrier, move, - and teardown, including a prefix held from an earlier callback. -- Assert re-entrant provider callbacks remain ordered behind the source chunk that caused the - write. -- Assert restore overlap across a transformed or delayed span requests a fresh snapshot rather - than slicing cleaned text. -- Assert `LocalPtyProvider`, daemon `Session`, and relay `PtyHandler` install the source-side seam; - assert `SshPtyProvider` does not reinterpret relay data. -- Assert WSL, SSH, and remote-runtime streams do not enable the native-Windows projection. -- Assert a capable daemon sanitizes live output, snapshots, pending records, checkpoints, and cold - restore; assert capable relay replay/history has the same property. Assert old daemon and relay - versions are detected and never represented as sanitized. - -### Authority and restore - -- Assert an early-consumed query is answered once by its source owner and never by renderer or - hidden model. -- Assert normal delivered/dropped query authority resumes after startup state clears. -- Assert the main snapshot, renderer snapshot, hidden reveal, reconnect, and mobile subscription do - not contain cooked OSC text. -- Assert replay never sends OSC or focus replies. -- Assert ordinary native console focus behavior remains enabled. -- Assert the focus harness captures both terminal `onData` and explicit reattach-focus writes. Any - later ownership implementation defines its tests in the required follow-up design. - -### End-to-end acceptance - -On native Windows, repeatedly create, hide, reveal, and reconnect new and resumed agent sessions. -Before typing, neither live output nor any restore path may contain `]10;rgb`/`]11;rgb`. Repeat the -focus/blur scenarios to classify `[I`; if it reproduces through an ownership race, this work stops -at the follow-up-design gate rather than claiming the symptom fixed. Application-owned focus -behavior must still move the TUI caret correctly after focus and reattach. Repeat with a plain -PowerShell terminal and a native focus-event consumer to prove no global regression. - -Run renderer and main PTY suites, runtime snapshot/query suites, node/web typechecks, lint, -formatting, max-lines ratchet, reliability gates, and Electron validation. SSH ingestion changes also -require the repository's SSH end-to-end procedure. - -## UI Quality Bar - -This is not a layout, styling, or copy change. Existing terminal rendering and focus behavior must -look unchanged except that matched protocol garbage is absent. A passing terminal screenshot has a -clean prompt, no clipped or duplicated startup output, no restore flash, and the existing cursor and -focus presentation. - -## Review Screenshots - -1. A fresh native-Windows agent prompt after startup, with no OSC reply text. -2. The same session after hide/reveal restore, still clean and without duplicated output. -3. The session after focus, blur, and reconnect, showing the focus-harness outcome and prompt state. -4. A plain native PowerShell terminal after focus/blur, showing unchanged adjacent behavior. - -## Rollout - -1. **Correct seam and rollback.** Remove the prototype filters. Add the shared serialized ingress - state machine, explicit raw-span emissions, and separate ACK accounting after shell-ready - preprocessing. Install pass-through mode in `LocalPtyProvider`, daemon `Session`, and relay - `PtyHandler` before their models, persistence/replay, and fanout. -2. **Protocol and authority contract.** Bump the daemon protocol, add relay capability/version gates, - carry atomic fresh-spawn intent, define legacy fallback, and amend the canonical model/query - authority documents with exact transfer events. -3. **Startup transaction.** Move OSC startup recognition/reply into source ingress, retain canonical - ST replies, consume answered queries for model and views, and retain raw sequence accounting. -4. **Windows compatibility projection.** Gate the measured projection on provider evidence; add FIFO - anchored recognition, serialized re-entrant delivery, lossless drains, false-positive coverage, - and authoritative daemon/model/snapshot tests. -5. **Focus evidence.** Land the real focus-path harness. If it proves a focus-ownership race, stop - for the required follow-up design; a direct snapshot or provider-transformation bug may be fixed - only with a failing regression test that selects that branch. -6. **Electron and SSH gates.** Validate visible, hidden, restored, mobile-owned, native console, WSL, - and SSH scenarios before removing the old startup implementation. - -Each slice must keep query authority singular. The compatibility projection does not ship without a -model-snapshot assertion, and no focus behavior change ships before the deterministic focus harness -fails on the old behavior and passes on the new behavior. - -## Lightweight Eng Review - -- Scope: limited to the proven OSC startup corruption plus deterministic focus evidence. Global - focus filtering and an unproven ownership state machine remain out of scope. -- Architecture/data flow: classification belongs at each PTY source owner after shell-ready - preprocessing and before every authoritative model, persistence, replay, or delivery consumer. -- Failure modes covered: partial/mismatched projections, false-positive collision, nested writes, - authority races, snapshot and teardown drains, protocol-version skew, reattach, and host - isolation. -- Test coverage required: byte-boundary unit tests for the shared transaction; local, daemon, relay, - runtime/mobile, restore, and legacy-protocol integration tests; real native-Windows provider and - renderer-focus harnesses; Electron and SSH end-to-end validation. -- Performance/blast radius: ordinary output is a pass-through emission. Buffering is bounded by one - startup reply candidate and its deadline. Protocol and sequence metadata touch every delivery - path, so existing high-throughput, ACK, hidden-drop, and reconnect tests are mandatory. -- UI quality bar: terminal layout and styling are unchanged; only matched startup garbage - disappears, without cursor/focus regressions or restore flashes. -- Required review screenshots: the four terminal states in `Review Screenshots`. -- Residual risks: the native projection may be too unstable to enable; exact projected application - output can collide; `[I` may require a separately reviewed focus-ownership design. - -## Non-Goals - -- Replacing xterm's general query parser. -- Filtering arbitrary escape-looking terminal output. -- Disabling ConPTY focus or Win32 input mode globally. -- Changing WSL, SSH, or remote-runtime terminal semantics to imitate local Windows. -- Solving unrelated MCP startup warnings reported beside the terminal garbage. - -## Final Invariants - -1.

This document is the hard gate -before a reproduction harness or production change. GitHub access during the -investigation was read-only, and no installed Orca daemon, pipe, token, process, -or terminal session was contacted or changed. - -## Findings - -The reported incident is a composition of three lifecycle paths, not one: - -1. **Survival and adoption:** normal app quit deliberately disconnects from - daemon clients without shutting down their PTYs. Protocol-specific named - pipes let multiple generations coexist, and legacy adapters intentionally - reconnect to them so live PTYs remain warm and reattachable across upgrades. -2. **Broad current-generation replacement:** - `cleanupDaemonForProtocol` sends the only production - `shutdown { killSessions: true }` request found in the repository. Its - production callers replace or explicitly restart the current generation; - legacy discovery does not call it. A failed `listSessions` is currently - converted to an empty list before this broad shutdown, which makes its - reported kill count untrustworthy but does not suppress the shutdown. -3. **Reconnect-triggered per-session destruction:** #8871 provides the strongest - causal evidence. A reconnecting renderer restores stale remote handles, - synthesizes `pty-exit`, drops that reason at `session.tabs.close`, and the - authoritative host interprets the close as user intent. Its PTY router then - forwards individual `kill` requests to whichever current or legacy adapter - claimed each reusable session ID during discovery. - -`client-hello` is necessary to discover and route legacy sessions, but neither -the hello handler nor legacy discovery sends a kill or shutdown request. The -~3.3-second renderer-bootstrap-to-kill evidence in #8871, repeated renderer -spawn/burst correlations, and the untyped close path are substantially stronger -than #9749's inference that greeting an old pipe causes that daemon to kill its -table autonomously. - -The immediate safety boundary is therefore destructive request authority and -provenance. Cross-profile, sleeping-session, and generation-retirement policy -remains the larger #9138/#9229 problem. - -## Deterministic native-Windows reproduction - -Reproduction snapshot: 2026-07-21 14:36 PDT (2026-07-21 21:36 UTC). - -`tests/e2e/daemon-generation-reconnect-safety.spec.ts` now constructs an -isolated `orca-9749-dg-*` runtime under the Windows temporary directory.

Each -canary records the PTY-root and descendant PID/start identity independently. -The fixture refuses cleanup outside its exact temporary root and terminates -only recorded fixture process incarnations; it never enumerates or connects to -installed Orca endpoints. - -The Electron-as-Node reconnect client performs three production -`DaemonPtyAdapter`/`DaemonPtyRouter.discoverLegacySessions` bursts, reattaches -every original PID, pings every canary, and opens a simultaneous second client -to each generation.

One v23 broad `shutdown reason:rpc killSessions:true` and repeated `shutdown-dispose-failed` were present. | **Supported composition, reporter causality not proven.** Versioned legacy adoption explains hellos; `cleanupDaemonForProtocol` explains broad shutdown; #8871's stale-mirror close echo best explains reconnect-time individual kills. `daemon-server.ts` logs `session-killed` before awaiting `host.kill`, so repeated records prove repeated requests, not repeated physical death. | No fix shipped for the destructive initiator. #9277 mitigates empty v24+ accumulation only. Skipping all legacy hello or killing legacy generations on sight would destroy the promised warm-reattach behavior and is unsafe scope creep. | -| [#9138](https://github.com/stablyai/orca/issues/9138) | Open; 2026-07-17; macOS 1.4.143/v22; observed v18/v20/v21/v22 | UI showed 8 sessions while about 46 Claude processes remained; removing stale trees removed about 370 processes and reduced swap from 25 GB to under 5 GB. | **Proven accumulation, ownership policy deliberately conservative.** Normal disconnect, versioned endpoints, incomplete cross-profile ownership, sleeping/cold restore, and legacy wildcard claims prevent safe blind retirement. Prototype commit `7c915909b` implements an audit/journal/incarnation design but is unmerged. | No complete fix shipped. #9277 safely handles only empty current-generation v24+ daemons. The broader ownership journal, grace period, all-profile evidence, and enforcement rollout belong here, not the immediate #9749 close-authority patch. | -| [#9211](https://github.com/stablyai/orca/issues/9211) | Closed duplicate 2026-07-17; v21/v22 | A v21 daemon remained four days beside v22, and each app launch greeted both. | **Proven intentional legacy discovery with missing retirement.** `createLegacyDaemonAdapters` plus `discoverLegacySessions`. | Consolidated into #9138; no separate shipped fix.

Three later fresh renderer processes correlated within about 1 s with bursts killing 4, 7, and 7 worktrees while app and daemon PIDs remained stable. | **Supported-to-proven request path.** Persisted remote handle → subscribe returns `no_connected_pty` → synthetic `pty-exit` → `closeTerminalTab(reason:'pty-exit')` → reason dropped from `session.tabs.close` → `closeMobileSessionTab` kills host PTY. Early pre-connect kills were correctly downgraded to unattributed. Close propagation intersects landed #8628 and later #8958. | Not fixed on main. This is the strongest immediate #9749 foundation. Trigger repair alone is insufficient; the authoritative host must adjudicate intent. | -| [PR #8872](https://github.com/stablyai/orca/pull/8872) | Open; 2026-07-15; head `bb69fac775`; rebased 2026-07-21 | Prevents mirror `pty-exit`/cleanup evidence from killing a host PTY while retaining real user close and dead-tab retirement. | **Actual diff/tests inspected.** Threads typed `user`/`pty-exit`/`cleanup`; host refuses non-user closes if any parent leaf has a connected PTY, republishes an unchanged snapshot with a guarded replay marker, and handles dead-leaf/live-sibling loops. Adds an optional daemon `kill intent:'auto'` guard, but intentionally sends no auto intent until protocol/capability negotiation exists. | Unshipped. The earlier Windows/WSL live matrix passed on an older head and was explicitly invalidated by the rebase, so native validation must be rerun. This is the best narrow safety foundation, but reasonless old clients remain destructive on a new host. | -| [PR #8888](https://github.com/stablyai/orca/pull/8888) | Open; 2026-07-15; head `b13235211`; reviews/follow-ups read | Ambiguous paired-runtime close RPCs could destroy host tabs with no requester attribution. | **Actual diff/tests inspected.** Default-denies intent-less paired-runtime `session.tabs.close`, `terminal.close`, and `terminal.closeTab`; validates user source/target, dedupes request IDs per device across reconnects, rate-limits, restricts create rollback to its connection, and traces device/connection/source/decision without bearer tokens. Adds local daemon-control client ID to `session-killed`. | Unshipped. Useful defense-in-depth and logging foundation. Its “old paired client gets successful no-op” behavior is safely conservative but needs explicit compatibility/product acceptance; taking the entire policy is broader than the smallest #9749 fix. | -| [#9414](https://github.com/stablyai/orca/issues/9414) | Open tracking issue; 2026-07-19 | Recognition-dependent terminal lifecycle actions can destroy or strand arbitrary processes. | **Proven design boundary.** Host owns adjudication; stale client transport state and agent-name recognition are not kill authority. Tracks #8872/#8888 and lifecycle-state work. | Unshipped tracker. Aligns with #9749 invariants; generic agent recognition work is separate scope. | -| [PR #8628](https://github.com/stablyai/orca/pull/8628) | Merged 2026-07-14 as `36cd8a334`; releases after that date | Tab close did not durably retire all associated terminal/session state. | **Actual merge diff inspected.** Centralized terminal retirement/ownership and ensured remote-owned closes reach the authoritative host. The remote call still carried no close reason, so lifecycle and user closes were indistinguishable. | Shipped and important context, not a regression to revert wholesale. #9749 must preserve its durable explicit-user close while adding authority. | -| [#8878](https://github.com/stablyai/orca/issues/8878) / [PR #9098](https://github.com/stablyai/orca/pull/9098) | Issue and PR open; 2026-07-15/17; PR head `9f3abd778` | A reconnecting paired client resumes a provider session still live on the host, producing duplicate TUIs. | **Proven companion feedback loop.** Client-local resume runs before authoritative mirror arrival; a #8871 kill also leaves a resume record. PR gates resume for runtime-owned worktrees while preserving the record. | Unshipped. Relevant reconnect stress case, but provider-session resume dedupe is not needed to stop #9749 kills. | -| [#9352](https://github.com/stablyai/orca/issues/9352) / [#9585](https://github.com/stablyai/orca/issues/9585) | Open; 2026-07-18/20; remote macOS and Windows | Closed or killed remote tabs return as `ptyId:null` phantoms; host snapshots keep dead terminal surfaces, and repeated host restarts accumulate them. | **Proven stale mirror/snapshot state.** Host `touchMobileSessionSnapshotsForPty` republishes the same tab; viewer mirrors every terminal surface. Remote transport also leaks the explicit-kill error. | Unshipped. Explains repeated stale close inputs and must be in stress coverage, but pruning dead surfaces is a separate lifecycle fix requiring sleeping-session care. | -| [#9217](https://github.com/stablyai/orca/issues/9217) / [#8970](https://github.com/stablyai/orca/issues/8970) | #9217 closed duplicate 2026-07-19; #8970 open; v1.4.143 | Agent/sidebar rows remain after local close or SSH relay connection loss. | **Proven UI/status lifecycle gaps.** SSH teardown intentionally preserves PTY ownership for reattach but omitted status clearing; renderer lacks a sweep. | Separate non-destructive roster cleanup.

Keep daemon-death regression coverage, but do not merge root causes. | -| [PR #8140](https://github.com/stablyai/orca/pull/8140) | Merged 2026-07-10 as `03a673708`/PR head `1710325e0`; fixes #8048 | Graceful then immediate Windows PTY teardown double-closed the same ConPTY handle and killed the shared daemon. | **Proven by actual native harness/diff.** `nodePtyKillIssued` makes later Windows force a no-op. Harness uses unique pipe/temp state, 25 victims, and a witness PTY/daemon survival assertion. | Shipped. Prevents one daemon-death path; does not authorize reconnect closes and does not retire descendants. Reuse its isolation/witness patterns only. | -| [PR #8284](https://github.com/stablyai/orca/pull/8284) | Closed unmerged 2026-07-16; head `ebe0b6523` | Proposed serial worktree PTY admission and verified fail-closed teardown across Windows/POSIX/SSH. | **Actual 50-file diff/tests inspected.** Retained shutdown ownership, admission fences, physical-exit proof, and Windows relay ConPTY ownership. | Contrary to the issue prompt, it did **not** merge. Landed work was split/superseded by #8661 and #8706. Its teardown patterns are useful, but adopting its broad branch is unsafe. | -| [PR #8661](https://github.com/stablyai/orca/pull/8661) | Merged before 1.4.146; key commit `a635ff9a7` | Disposal failure could prevent orderly runtime/daemon termination. | **Proven current source behavior.** Shutdown RPC catches `host.dispose`, logs `shutdown-dispose-failed`, then continues fencing, client destruction, and server close; resource disposal is retried. | Shipped before #9749. Corrects the report's inference that the failure necessarily leaves the endpoint authoritative forever. A native handle may still keep a process alive, but the server intends to close. | -| [#9045](https://github.com/stablyai/orca/issues/9045) | Open; 2026-07-16; Windows | Worktree deletion fails because agent descendants retain filesystem handles after PTY teardown. | **Supported descendant ownership gap.** Root PTY exit is not full tree exit on Windows. | Unresolved. It concerns cleanup after a legitimate kill, not who may initiate it. | -| [#9704](https://github.com/stablyai/orca/issues/9704) | Open; 2026-07-21; Windows 1.4.147/v24 | Killed PTY descendants survive (six trees/18 processes/~1.1 GB, later ~2 GB); runtime lists dead sessions as connected. | **Proven descendant leakage plus stale registry.** Explicitly asks for initiator attribution rather than assuming the kill was valid. | Unresolved. Different from #9749 because the root session was killed; #9704 concerns what survives afterward. | -| [PR #9752](https://github.com/stablyai/orca/pull/9752) | Open; 2026-07-21; head `6be947317` | Windows agent descendants survive explicit or natural PTY-root exit. | **Actual native patch and tests inspected.** Suspends recognized native-Windows agent ConPTY roots, creates/configures/assigns a kill-on-close Job Object before resume, owns the handle atomically, and falls back to direct-root termination. Plain terminals, WSL, POSIX, SSH relay, and unrelated sessions are excluded; Windows process-table commands are removed. | Unshipped. Correct post-authorization cleanup, explicitly not an initiator fix. Combining it into the #9749 authority patch would obscure causality; compose/test separately if it lands first. | -| [PR #9266](https://github.com/stablyai/orca/pull/9266) / [PR #9612](https://github.com/stablyai/orca/pull/9612) | Both open; 2026-07-18/20 | Alternative Windows descendant tree termination using process enumeration/taskkill-style sweeps. | **Competing cleanup approaches.** Carry PID-reuse, access-denied, cost, and partial-tree risks that native Job ownership avoids. | Unshipped.

How generations survive - -1. **2026-07-15 13:50 local:** #9749's v21 daemon starts. -2. An app quit/update runs `disconnectDaemon`, whose adapter `disconnectOnly` - closes client sockets and leaves live PTYs/history reattachable. The daemon is - detached/unref'd, so parent death is not daemon death. -3. **2026-07-18 14:26 local:** a v22 daemon starts on a different versioned - endpoint while v21 retains its PTYs. -4. **2026-07-20 14:50 local:** v23 starts while both prior endpoints remain. -5. Windows endpoints are generated by - `getDaemonSocketPath(runtimeDir, protocolVersion)` as - `\\?\pipe\orca-terminal-host-v-`. - Tokens and PID records are likewise protocol-specific files. No endpoint - collision forces an old generation out. -6. Before protocol 24, a non-empty daemon had no generation-retirement - protocol. Since #9277, an empty v24+ daemon can atomically self-retire, but a - live session intentionally blocks it and v23-or-older behavior is unchanged. -7. #9749's claim that `shutdown-dispose-failed` necessarily leaves the pipe open - is not source-proven for 1.4.146. Commit `a635ff9a7` catches disposal failure - and continues ordinary shutdown; #9277 additionally closes admission first. - A stuck native handle may keep a process alive, but the endpoint is meant to - stop being authoritative. - -### B. Why startup greets every surviving generation - -1. Current startup establishes the v25 (v24 in the reporter build) adapter and - its complete control/stream lifecycle lease. -2. `createLegacyDaemonAdapters(runtimeDir)` loops every value in - `PREVIOUS_DAEMON_PROTOCOL_VERSIONS`, derives that version's pipe/token/PID - paths, and probes each endpoint. -3. A responsive endpoint receives a `DaemonPtyAdapter` configured with that - exact old protocol. It has no respawn callback, because new code must not - recreate old environment semantics. -4. `DaemonPtyRouter.discoverLegacySessions()` calls `adapter.listProcesses()` - for each legacy adapter. -5. `listProcesses()` calls `ensureConnected()`. `DaemonClient.doConnect()` opens - a control socket, sends hello, then opens a stream socket and sends hello - using one client UUID. This is the precise source of each control/stream pair - in #9749 at `16:41:32.277Z` through `.286Z`. -6. v24+ hellos return PID/start-time/launch-nonce and require both sockets to - match. Old protocols return no identity, so successful token+protocol hello - authenticates the endpoint but cannot prove a process incarnation. -7. `listSessions` results populate `sessionAdapters: Map`. - That map is keyed only by reusable session ID, not daemon/session - incarnation; a later generation can overwrite an earlier claim. -8. No code in hello acceptance, adapter construction, or discovery sends - `kill`, `shutdown`, or `shutdownIfIdle` to a legacy daemon. - -### C. Exact broad shutdown caller - -1. Current-daemon replacement/manual restart/full cleanup calls - `cleanupDaemonForProtocol(runtimeDir, PROTOCOL_VERSION)` (or the explicitly - supplied current handle protocol). -2. It probes that version's endpoint and creates a `DaemonClient` for the same - protocol. -3. It connects with the same control/stream hello sequence. -4. It requests `listSessions`; any error is converted to `{ sessions: [] }`. -5. It then unconditionally sends `shutdown { killSessions: true }` and treats a - reply race with daemon exit as success. -6. `daemon-server.ts` logs `shutdown reason:'rpc' killSessions:true`, begins the - ordinary shutdown admission fence, awaits `host.dispose`, logs but catches - `shutdown-dispose-failed`, writes the reply if possible, disposes resources, - destroys clients/transports, unlinks owned identity artifacts, and closes - the server. -7. Repository search found no other direct production sender of - `shutdown { killSessions: true }`. Legacy adapter discovery is not a caller. -8. Unsafe residual: list failure cannot be treated as proof of emptiness for - any future generation reaper, and broad shutdown still lacks an origin, - daemon-incarnation, ownership, and intent audit record. - -### D. Supported reconnect-to-mass-kill path - -1. **Renderer bootstrap T+0:** a paired desktop/runtime renderer hydrates - persisted mirrors containing process-lifetime remote terminal handles. -2. **T+milliseconds:** before the fresh authoritative session snapshot fully - reconciles, remote transport subscribes using a stale handle. -3. The host cannot resolve a connected PTY for that handle and returns a gone - condition; remote transport synthesizes `pty-exit`. -4. `Terminal.tsx` calls `closeTerminalTab(tabId, { reason: 'pty-exit' })`. -5. Current main uses that reason for local retirement behavior but - `closeWebRuntimeSessionTab` sends only `{ worktree, tabId }`. -6. Runtime RPC `session.tabs.close` has no origin/intent in its schema or - handler. `OrcaRuntimeService.closeMobileSessionTab` treats it like an - explicit user request and invokes either direct `ptyController.kill`, a - whole-parent renderer close, or headless teardown. -7. For daemon-backed terminals, the PTY controller is the `DaemonPtyRouter`. - `adapterFor(sessionId)` uses the discovery map to select a current or legacy - generation and its adapter sends `kill { sessionId, immediate }`. -8. The owning daemon logs `session-killed` before awaiting `host.kill`. This is - why app and daemon PIDs remain alive while real terminal sessions disappear. -9. **#8871 observed T+3.348 s** for the first bootstrap-to-kill incident. Three - other new renderer processes aligned within about one second with 4-, 7-, - and 7-worktree kill bursts. -10. Stale host tab surfaces (#9352/#9585), persisted client mirrors, reconnect - retries, and republished snapshots can invoke the same close again. If the - daemon still retains the session entry or physical exit is unresolved, a - reconnect can rediscover and target the same ID again. Because logging - precedes the awaited kill, repeated `session-killed` records can also be - repeated failed/not-yet-settled attempts; they do not prove a dead process - was resurrected and killed twice. - -### E. Why adjacent bugs are different - -- **#8275/#8048/#8140:** PTY teardown double-closes a Windows ConPTY native - handle and the shared daemon dies. There is no broad shutdown event. All - sessions disappear because their owner process died. -- **#9704/#9045/#9752:** a valid or invalid kill has already targeted the PTY - root, but Windows descendants remain and retain memory/files. The owner stays - alive or the registry stays stale. This is cleanup completeness after a kill, - not destructive authority. -- **#9749/#8871:** app and daemons remain alive. Explicit RPCs reach live daemon - sessions because stale client lifecycle evidence is interpreted as intent. - -## Compatibility behavior that must remain - -- App quit is a disconnect, not terminal shutdown. -- Same-protocol daemon survival across packaged Windows updates (#7538) avoids - terminating live work. -- Old-protocol adapters remain addressable after an upgrade so mounted and - sleeping PTYs can reattach (#2974, #8768, #8817). -- Legacy daemons cannot be judged empty from one current profile or renderer. - Missing ownership data, inactive profiles, sleeping sessions, remote/SSH - routes, and legacy claims all mean keep/audit. -- Current protocol 24+ can retire only after its own atomic server-side idle - predicate proves there is nothing to preserve. -- Older clients/servers must not infer support from an ignored additive field. - In particular, no caller may send daemon `kill intent:'auto'` until a - protocol bump or negotiated capability proves the daemon will enforce it. - -## Direction comparison - -| Direction | Immediate safety | Compatibility and failure mode | Decision | -| ------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------- | -| Skip `client-hello` for every old protocol | Avoids routing kills to legacy sessions, but also makes their live PTYs invisible/unattachable. | Directly violates warm legacy reattachment and converts preservation into inaccessible leaks. | Reject. Hello is not the authority bug. | -| Force-exit on `shutdown-dispose-failed` | Bounds a half-shutdown process if endpoint fencing and handle cleanup are correct. | Can silently destroy promised live PTYs; does not stop reconnect close RPCs; overlaps #9752 descendant semantics.

The -three-generation harness must decide whether #8888's default-deny/dedupe layer -is also required for old-client and repeated-reconnect safety. Full generation -retirement stays in #9138/#9229. - -## Harness gate for the next phase - -The first executable artifact will be an isolated native-Windows harness, not a -production edit. It must: - -- allocate a temporary runtime/user-data root and unique pipe namespace; -- launch three disposable protocol fixtures (for example v21/v22/v23) with - distinct live canary children plus stale/terminating table entries; -- use the real `DaemonClient`, legacy adapter discovery, router, and runtime - session-close path where feasible instead of calling a proposed helper; -- prove hello/discovery alone is non-destructive; -- separately trigger the exact broad current-protocol shutdown caller and the - reconnect stale-mirror close path; -- distinguish daemon/app liveness, PTY-root liveness, and descendant liveness - with independent counters and process handles; -- repeat reconnect bursts and record duplicate requests for a retained ID; -- model a PTY owner whose disposal never proves physical exit and assert a - bounded, non-authoritative endpoint state; -- cover current→next protocol upgrade, same-version quit/relaunch, profile - switch, remote-server paired client, multiple simultaneous clients, mixed - client/server versions, and WSL/SSH routing boundaries; -- validate PID/start identity, dead parent, access-denied identity probes, no - listener/pipe/handle leaks, and no CIM/PowerShell per-session hot path; -- guarantee cleanup in `finally` using only fixture-owned exact PIDs, handles, - files, and pipe names. - -Externally visible RED invariants are: reconnect kills one or more canary PTYs -while the app/fixture processes remain alive; repeated stale input can issue -another destructive request for the same retained incarnation; and a refused -disposal does not reach a bounded terminal endpoint state. The post-fix GREEN -invariants are survival of every unrelated canary, one exact kill for an -explicit user target, legacy warm reattachment, bounded retirement fencing, and -zero leaked fixture processes/handles/pipes. - -## Implemented immediate safety boundary - -Implementation snapshot: 2026-07-21 15:26 PDT (2026-07-21 22:26 UTC). - -The initial implementation used a 30-second capability cache keyed only by -runtime-environment ID. That was rejected before finalization: a positive -`status.get` result could outlive a server replacement under the same -environment, and the later destructive request had no proof that it reached the -generation that supplied the capability. - -The implemented boundary makes compatibility and identity validation atomic -with the lifecycle request: - -1. Explicit user closes remain on `session.tabs.close`, preserving the durable - host-owned close behavior shipped by #8628 and compatibility with old - servers that ignore the additive `reason:'user'` field. -2. Renderer-originated `pty-exit` and `cleanup` echoes use the additive - `session.tabs.closeLifecycle` method. An old server returns - `method_not_found` before entering its legacy destructive close handler. The - client clears optimistic close suppression and requests an authoritative - snapshot; it never falls back to `session.tabs.close`. -3. The lifecycle method requires both the `publicationEpoch` observed in the - host snapshot and the exact terminal handle observed for that tab. Missing - evidence means keep, refresh, and audit rather than kill. -4. The host refreshes its PTY records, rejects a different publication epoch, - rejects a terminal handle that no longer belongs to the addressed parent, - rejects when provider liveness is unavailable, and rejects while any parent - leaf still has a connected PTY. Refusals carry a bounded reason - (`stale-publication`, `stale-terminal`, `unknown-liveness`, - `live-host-pty`, or `retirement-owner`) and republish only when doing so - cannot create the known dead-leaf/live-sibling echo loop. -5. A lifecycle close never signals a PTY or relays a renderer close. A dead - whole headless parent can be retired from persisted/runtime state with - `killPtys:false`; a renderer-owned parent or partial split remains with its - authoritative owner. Thus a reusable tab ID or incomplete provider read - cannot become destructive authority. -6. Reasonless closes from authenticated legacy mobile or runtime clients retain - their pre-change explicit-user meaning, so upgrading only the host does not - break close. Their old lifecycle/user ambiguity remains until the client - upgrades; unattributed in-process reasonless calls are refused and replayed. -7. Renderer close intents are scoped by runtime environment and worktree, and - terminal-incarnation evidence must match that exact runtime environment. - Identical tab/worktree IDs in another profile cannot suppress or authorize - this profile's retirement. - -The RPC span records origin/client kind, close reason, connection ID, request -ID, publication epoch, and allow/refusal decision. It does not record terminal -contents, authentication tokens, or environment secrets. The legacy adapter -hello/discovery path, warm PTY adoption, daemon shutdown protocol, and Job -Object descendant cleanup remain unchanged. - -This is the smallest immediate #9749 fix. Cross-profile generation inventory, -all-profile ownership evidence, sleeping-session policy, and explicit daemon -handoff/retirement remain #9138/#9229. Windows descendant reaping after an -authorized kill remains #9704/#9752. - -## GREEN evidence - -The post-fix native-Windows run completed at 2026-07-21 15:25 PDT: - -- v21/v22/v23 used distinct versioned named pipes under a disposable runtime - root, with six independent PTY-root/descendant canaries; -- three reconnect discovery bursts plus simultaneous clients opened the real - control/stream hello pairs without destructive side effects; -- desktop and two remote/profile connection identities attempted each stale - mirror retirement three times, then a full reconnect-client process - exit/relaunch repeated the same persisted IDs for six attempts total; -- the lifecycle requests traversed the production schema, dispatcher, - `OrcaRuntimeService`, and `DaemonPtyRouter` using publication/terminal - incarnation claims; -- every daemon, PTY root, and descendant remained alive while the app/client - process remained alive; -- the contained refusal-to-exit PTY produced `shutdown-dispose-failed`, lost - named-pipe authority within the bounded deadline, and was cleaned by exact - fixture-owned process identity; -- the reconnect/relaunch test passed in 42.9 seconds and the bounded-disposal - test passed in 15.2 seconds. - -Focused verification at this checkpoint: node and web typechecks passed; -changed-file `oxlint` and `git diff --check` passed; 181 focused renderer/RPC -tests passed; and 12 host close-adjudication tests passed (784 unrelated tests -filtered out). No PowerShell/CIM process-per-session path, polling loop, broad -installed-daemon discovery, or Job Object implementation was added. - -Additional validation completed at 2026-07-21 15:48 PDT: - -- the native generation harness passed 25 reconnect bursts in 52.1 seconds; - every v21/v22/v23 daemon and all six PTY-root/descendant canaries survived; -- the mixed-version daemon-lifecycle E2E kept the non-empty v22 daemon - reattachable while the empty current v24 daemon retired through #9277; -- a fresh `pnpm build:electron-vite` and a fresh paired-web-client build both - completed successfully; -- 182 remote-runtime, multi-client, remote-server parity, SSH-provider, WSL - host-context, and remote PTY transport tests passed; -- the complete runtime service/RPC group passed 884 of 885 tests. The lone - failure, `preserves existing badgeColor on runtime createRepo dedupe`, is an - existing Windows-only POSIX path expectation (`/tmp/...` versus - `\\tmp\\...`) in code untouched by this change; every close, remote, SSH, - and WSL case in that run passed; -- CLI typecheck, switch-independent changed-file lint, reliability gates, - max-lines ratchet, and `git diff --check` passed. The repository-wide - switch-exhaustiveness command is blocked by the pre-existing unmatched - `undefined | 'current' | 'duplicate'` cases in - `skill-freshness-group.tsx`, outside this diff. - -Two practical Electron runs exposed setup/teardown limitations without -contradicting the close-safety result: - -- `restart-restore-terminal-input.spec.ts` completed the clean-restart, live - daemon, restored-output, keyboard-input, and direct-input assertions, then - failed only in `RestartSession.dispose()` with `EPERM` deleting its isolated - profile. Restart Manager and Sysinternals Handle found no surviving file - lock after teardown; the exact fixture root deleted successfully later - without terminating a process. The same failure reproduced with the temp - root inside this worktree and with the production diff to - `orca-restart.ts` empty, so it is recorded as a fixture cleanup limitation, - not a session-liveness failure; -- the paired-browser navigation E2E built the web client and launched the - isolated desktop, but timed out before pairing because its host fixture - displayed `No workspaces found`. The deterministic multi-client runtime - integration passed; no terminal-close assertion failed in this E2E. - -All diagnostic downloads and worktree-local E2E temp roots were removed by -their exact verified paths. No installed Orca daemon pipe or real user terminal -was discovered, greeted, stopped, or mutated during these runs. - -## Internal review-until-clean and final native evidence - -The requested `$internal-review-until-clean` loop ran against merge base -`937a2015eaf85144d02848c5b6d4c09ecd423830`. Round 1 found and fixed four -in-scope safety defects: - -- lifecycle retirement could still relay a destructive renderer close or kill - retained/disconnected headless IDs; lifecycle requests now never signal a - process and only state-retire a dead whole headless parent; -- an unavailable/access-denied PTY inventory was treated like authoritative - absence; it now returns `unknown-liveness` and keeps/audits; -- pending close intent was keyed only by worktree and could cross-contaminate - two runtime profiles; it is now scoped and cleaned by environment/worktree; -- the harness accepted a two-second PID start-time tolerance; capture and - revalidation now compare the same CIM `CreationDate` exactly. - -The elegance pass also removed an unnecessary cached capability probe. The -additive method dispatch on the exact connection is the atomic compatibility -boundary; a cached positive result could outlive server replacement. The -performance pass found no production polling, process enumeration, listener, -or subprocess addition. The existing bounded controller inventory refresh is -unchanged in frequency, snapshot refreshes coalesce per environment/worktree, -and all added tracking maps have completion or ownership cleanup. Round 2 -re-interrogated the full diff and found no remaining proven in-scope issue. -After strengthening the native harness to invoke production desktop discovery, -round 3 found one Windows-only test defect: three scanner tests modeled a live -v9 endpoint through POSIX `existsSync` but let every Windows named-pipe probe -connect. Their socket mock now accepts only v9 and errors every other version; -all 133 daemon lifecycle tests pass. The subsequent full-diff review is clean. - -The latest native Windows run captured its event reconstruction at -2026-07-21 16:58 PDT (2026-07-21 23:58 UTC). It launched v21/v22/v23/v24/v25 -on isolated versioned named pipes, then called the same -`createLegacyDaemonAdapters` scanner as desktop startup: the v25 client found -exactly v21-v24. Every generation accepted 16 reconnect control/stream hellos; -desktop and two remote-profile paths sent six lifecycle attempts for each -persisted stale-mirror ID across process relaunch. All five daemons, all ten -PTY roots, and all ten descendants were alive afterward, with zero -`session-killed` events. This directly covers the v24→v25 current-to-next -upgrade boundary while keeping older generations reattachable. - -The bounded `shutdown-dispose-failed` scenario also passed and now separates -authority from liveness explicitly: the late connection failed after endpoint -fencing while the refusing daemon, PTY root, and descendant remained alive -until exact fixture cleanup. The full Playwright command, including a fresh -Electron E2E build, exited successfully in 137.1 seconds, and no -`orca-9749-dg-*` directory remained. A final no-rebuild rerun passed both -scenarios in 99.1 seconds; the practical Electron clean-relaunch check passed -again in 24.0 seconds, and mixed-version retirement/live-session preservation -passed 2/2 in 23.1 seconds. - -Latest focused verification includes 15/15 host adjudication tests, 948/949 -focused production/RPC/renderer tests, 133/133 daemon discovery/adoption/ -retirement/access-failure tests, all three typechecks, and 215 -remote-runtime, multi-client, remote-server, SSH-provider, WSL-context, remote -PTY, and shared-control tests. The sole focused failure remains the untouched -Windows `/tmp` normalization baseline documented above. The experimental -`terminal-session.daemon-generation-reconnect-safety` reliability gate records -the invariant, RED/GREEN oracle, performance budget, promotion criteria, and -known platform/provider gaps. - -## Fresh PR review after current-main integration - -The explicitly requested post-PR `$internal-review-until-clean` pass completed -at 2026-07-21 18:02 PDT after merging `v1.4.150-rc.0` main, including the -remote-runtime network-recovery work from #9774. It found and fixed three -additional contract gaps: - -- a stale PTY-exit callback could borrow a replacement or sibling handle from - tab-wide state; lifecycle evidence now comes only from the exact callback PTY; -- the legacy close endpoint accepted lifecycle reasons without incarnation - evidence; it now accepts only explicit user intent, with reasonless - compatibility retained for authenticated legacy mobile and runtime clients; -- keep-on-unknown preserved the PTY but could leave its client mirror hidden; - the host now republishes unchanged authority when inventory is unavailable. - -The PR feedback loop also corrected the bulk-close payload assertion and made -the fixture protocol list collision-safe. The final native no-build run passed -both scenarios in 98.8 seconds, the fresh-build run passed in 137.1 seconds, -mixed-version retirement passed, and practical Electron restart/input passed -two scenarios with one intentionally skipped wedge scenario. Current-main -remote recovery (112 tests), focused close/reconnect suites, all 15 host -adjudication cases, all typechecks, reliability gates, max-lines, changed lint, -formatting, and diff checks pass. The full lint command remains blocked only by -pre-existing current-main switch-exhaustiveness and localization findings; no -remaining in-scope review finding is open. - -## Additional clean review after `v1.4.150-rc.0` integration - -This additional requested `$internal-review-until-clean` pass completed at -2026-07-21 18:56 PDT (2026-07-22 01:56 UTC) against merge base -`4d0e3f51ce0325a8f4670b4074618494984ab63d`. Round 1 found and fixed four -in-scope evidence/performance gaps: - -- the native harness omitted production `DaemonPtyRouter.listProcesses`, so - its synthetic lifecycle closes could pass through `unknown-liveness`; it now - routes the production inventory, uses worktree-prefixed daemon session IDs, - and requires every close to return `live-host-pty` with a republished - snapshot; -- concurrent reconnect closes each started a full cross-generation PTY - inventory; the host now shares one in-flight inventory and a deterministic - count test proves two concurrent closes call `listProcesses` once; -- the renderer introduced a second snapshot-refresh map; it now reuses the - existing environment/worktree remote-session deduper used by PTY reconnect; -- the reliability gate omitted the parked-tab callback path; its exact exiting - PTY incarnation assertion is now part of the gate. - -The review also added a wire-compatibility assertion proving that the additive -`{ reason: 'user' }` field is stripped by the previous `ActivateTab` server -schema. The repeated elegance and performance interrogation found no remaining -avoidable infrastructure, polling, subprocess churn, listener/handle leak, or -unbounded reconnect work. Round 2 re-read the full production and fixture diff, -constructed stale-publication, stale-handle, concurrent-close, mixed-client, -and old-server failure paths, and found no remaining proven in-scope issue. - -Fresh verification includes all three typechecks; reliability-manifest, -max-lines, changed-file lint, formatting, and diff checks; 175 remote snapshot -and PTY transport tests; and the isolated lifecycle/reconnect adjudication -group. The strengthened native five-generation Windows harness passed after a -fresh Electron E2E build in 137.2 seconds, required `live-host-pty` for every -synthetic close, left every daemon/root/descendant alive, and left no -`orca-9749-dg-*` directory. The full focused gate reached 992/993 passing tests; -the only failure remains the untouched Windows `/tmp` versus `\\tmp` -`createRepo` baseline. The newly merged headless-update group reached 143/144 -passing tests plus 25 skips; its only failure is an untouched LF-only -source-text assertion that does not match CRLF on Windows. - -## Completion evidence matrix - -| Original acceptance requirement | Authoritative evidence | Status | -| ------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------ | -| Complete recursive issue/PR/commit/tag investigation before production edits | The 41-row investigation matrix above, release chronology, and timestamped call-flow reconstruction cover every required starting item and every directly discovered related item.

Review findings are absorbed into the invariants and implementation below. - -Validated against `origin/main` at `21dee21a6d9d398bb332ddf0f85fbb4d5de7cd1b`. Current main includes remote-runtime resume/online recovery (#8255), worktree-owned multi-host routing (#10986), negotiated paired close intent (#10129), fail-closed runtime SSH setup (#10799), terminal-view parking (#11016), host-correct SSH folder adoption (#10818), hydration-loop ID indexes (#10891), runtime output chunking (#10915), consolidated changed-code quality gates (#11117), orchestration migration safety (#11107), and CLI-compatible remote timeout parsing (#11206). None replaces the direct desktop SSH reconnect path, but each constrains its ownership and lifecycle integration below. - -Scope: direct SSH reconnect recovery across main, preload, and renderer - -## Summary - -One direct SSH reconnect currently starts two sequential target-preparation waves, or three when a nonempty remote-workspace snapshot is applied. Each wave refreshes every target repo and then lineage. Because the next preparation starts after the previous one settles, the existing in-flight repo coalescer does not collapse these sequential scans. Simultaneous targets multiply the work, while disconnect handling separately calls the single-tab `clearTabPtyId` action once per live tab. - -Replace this with host-qualified, epoch-fenced provider reads and a renderer coordinator with two distinct modes: - -- reconnect finalization retries the exact target's terminal panes immediately, before optional discovery; -- preparation-only refreshes the exact target's catalog, worktrees, and lineage without remounting panes. - -Main owns one provider-incarnation authority per direct SSH target. It is a strict composition of the existing `connectionGeneration` and a new opaque `providerEpoch`: one helper rotates both atomically on the same transition set, and provider work carries and compares the pair. Existing file-mutation fencing continues to carry `connectionGeneration`, but it now advances on every provider-invalidating transition too; reconnect recovery cannot advance one clock without revoking the other. Every authoritative request carries the exact execution host and captured authority through preload to main; main selects the provider by that complete identity and revalidates the authority before any durable side effect. Renderer preparation deduplicates only overlapping work with identical concrete inputs. A completed preparation is not cached for the lifetime of an authority. - -Direct SSH provider calls use a dedicated fair limiter with five local slots, explicit deadlines, and cancellation. Cancel acknowledgement means local waiter settlement; the existing fire-and-forget `rpc.cancel` does not acknowledge relay-handler completion. A separate cancel-debt allowance bounds replacement admission while relay work may be finishing. The five-slot bound applies only to locally unsettled detected-worktree provider calls submitted by this coordinator; aggregate telemetry reports the late-work allowance and other same-relay traffic separately. Runtime discovery, sidebar refreshes, filesystem events, catalog reads, and lineage reads retain their own concurrency behavior and are measured separately. - -This remains separate from the sidebar fix in `9d3ae3adc7`, which does not own `ssh:state-changed`, remote-workspace preparation, or terminal binding cleanup. - -## Goals - -- Recover terminal panes without waiting for Git discovery on the same or another target. -- Keep coordinator-owned direct SSH provider work bounded and fair across targets. -- Make provider selection correct when repo IDs collide across local, direct SSH, and remote-runtime hosts. -- Reject obsolete provider results before any main or renderer authoritative mutation. -- Preserve final-state convergence for later same-connection remote snapshots and wake refreshes. -- Keep disconnect and retry scope symmetric across Git worktrees and folder workspaces. -- Preserve relay reattach identifiers and terminal/session recovery semantics. -- Make timeout, cancellation, non-authoritative data, and operational failure separately observable without exposing identifiers. - -## Non-goals - -- Changing SSH credentials, backoff policy, or user-facing reconnect controls. -- Moving runtime-owned work into the direct SSH coordinator. -- Changing the component-scoped sidebar refresh queue added by `9d3ae3adc7`; the shared detected-worktree provider coalescer does gain lease accounting. -- Expanding remote-workspace serialization to folder workspaces. -- Changing Git commands, worktree parsing, or Git capability detection. -- Changing the remote-runtime wire protocol. -- Establishing a renderer-wide or application-wide provider-call ceiling. - -## Current flow and root cause - -### Connected path - -`applySshConnectionStateChange` currently: - -1. filters `store.repos` by raw `connectionId`; -2. calls `Promise.all(remoteRepos.map(fetchWorktrees))`; -3. calls `fetchWorktreeLineage`; -4. scans target worktrees and bumps terminal generations one worktree at a time; and -5. calls `syncRemoteWorkspaceAfterConnect`. - -`syncRemoteWorkspaceAfterConnect` calls `prepareRemoteWorkspaceTarget`, repeating repo and lineage refresh. A nonempty snapshot then reaches `applyRemoteWorkspaceSnapshot`, which prepares a third time. - -For a target with `R` repos, the connected path therefore performs `2R` detected-worktree scans and two lineage reads without a snapshot, or `3R` scans and three lineage reads with one. The existing detected-worktree single-flight joins only requests whose provider reads overlap. These preparation waves are sequential in the current call chain, so it does not collapse their scan count. Other overlapping callers can still join a scan; telemetry must measure observed calls rather than infer a global `kR` multiplier. - -### Disconnect path - -Terminal failure states walk repo-derived worktrees and call `clearTabPtyId(tab.id)` for each tab whose `ptyId` is present. The general single-tab action scans workspace buckets, clones global terminal maps, publishes store changes, bumps worktree activity, and can persist metadata on every call. - -For `T` live tabs, `W` workspace buckets, and terminal maps of size `M`, synchronous work is approximately `O(T × (W + M))`, plus repeated Zustand publications and session-persistence debounce resets. Connection loss is not user activity. - -### Boundary and ownership defects - -- Renderer `fetchWorktrees(repoId, { executionHostId })` uses the host to choose and stamp renderer ownership, but the local preload/main request currently carries only `repoId`. -- Main then calls first-match `store.getRepo(repoId)` and cannot enforce the renderer's intended host. The proven producer is renderer-catalog aliasing across hosts, not duplicate UUID rows created by main; same-ID main rows remain a defensive ambiguity case. -- Main can prune lineage and backfill metadata before renderer receives a result, so a renderer-only stale-result fence is insufficient. -- Current main-owned `connectionGeneration` and the renderer-local state-change counter have different sources and advance rules. Only the main-owned value is authoritative. -- Relay replacement can change the provider incarnation without advancing the existing main-owned generation. The correction is to rotate the generation and provider epoch together, not to use the renderer counter. -- Raw repo-ID filtering can select another execution host. Folder workspace keys are omitted entirely. -- Direct SSH catalog and lineage preparation follows focused-runtime ownership in some paths. -- Direct SSH lineage preparation currently calls bare `fetchWorktreeLineage()`, whose ownership can follow focused-runtime settings rather than the SSH target. - -### Deterministic current-main baseline - -The falsifiable current-main invariants are: - -1. one connected direct SSH event must issue at most one detected-worktree scan per exact repo input and one host-qualified lineage read; -2. an authoritative detected-worktree or lineage result must identify one exact execution host and, for direct SSH, the complete provider authority; -3. explicit worktree, repo-derived, runtime-owner, folder, and PTY provenance must not contradict one another; and -4. a first timeout classified as retryable must not release lineage, sync, or token creation before its retry reaches a terminal outcome. - -Current main violates the first two at the smallest deterministic seams: - -- `applySshConnectionStateChange` runs `fetchWorktrees` plus lineage and then calls `syncRemoteWorkspaceAfterConnect`; -- `syncRemoteWorkspaceAfterConnect` calls `prepareRemoteWorkspaceTarget`, and a nonempty snapshot calls `applyRemoteWorkspaceSnapshot`, which calls it again; -- the shared renderer coalescer joins only overlapping promises and deletes the entry when they settle, so these awaited sequential waves remain `2R` scans and two lineage reads without a snapshot or `3R` and three with one; -- renderer refresh selection accepts `executionHostId`, while preload `worktrees.listDetected` and main `worktrees:listDetected` accept only `{ repoId }`; main then uses first-match `store.getRepo(repoId)`. - -Baseline commands run from the rebased worktree: - -```bash -pnpm install --frozen-lockfile -rg -n "prepareRemoteWorkspaceTarget|applyRemoteWorkspaceSnapshot|syncRemoteWorkspaceAfterConnect|store.fetchWorktrees|fetchWorktreeLineage" src/renderer/src/hooks/useIpcEvents.ts -rg -n "listDetected: \\(args: \\{ repoId: string \\}\\)|store.getRepo\\(args.repoId\\)" src/preload/api-types.ts src/main/ipc/worktrees.ts -pnpm exec vitest run --config config/vitest.config.ts src/renderer/src/store/slices/worktrees.test.ts -t "coalesces concurrent duplicate refreshes for the same repo and host|keeps same-repo refreshes separate for different execution hosts|fetches the requested host when duplicate repo ids exist" -pnpm exec vitest run --config config/vitest.config.ts src/main/ipc/worktrees.test.ts -t "coalesces concurrent authoritative detected worktree scans" -pnpm exec vitest run --config config/vitest.config.ts src/renderer/src/hooks/useIpcEvents.test.ts -t "clears stale remote PTYs when an SSH connection fully disconnects|waits for the remote workspace client id before dropping self notifications" -pnpm exec vitest run --config config/vitest.config.ts src/renderer/src/hooks/ssh-reconnect-pane-retry.test.ts -pnpm exec vitest run --config config/vitest.config.ts src/main/ipc/ssh.test.ts src/main/ssh/ssh-channel-multiplexer.test.ts src/renderer/src/runtime/use-remote-runtime-recovery-triggers.test.ts -t "surfaces relay channel loss while the SSH connection remains alive|does not broadcast a premature connected when relay deploy fails|times out after 30s with no response|advances both recovery schedulers" -pnpm exec vitest run --config config/vitest.config.ts src/renderer/src/components/terminal-pane/terminal-hidden-view-parking.test.ts src/renderer/src/components/terminal-pane/use-manual-terminal-worktree-parking.test.ts src/renderer/src/lib/manual-terminal-worktree-parking.test.ts -pnpm exec vitest run --config config/vitest.config.ts src/renderer/src/lib/agent-background-session-launch-host.test.ts src/renderer/src/lib/launch-agent-background-session-remote.test.ts src/renderer/src/hooks/useAutomationDispatchEvents.test.ts src/renderer/src/components/terminal-pane/pty-connection.test.ts -pnpm exec vitest run --config config/vitest.config.ts src/renderer/src/store/slices/worktree-by-id-index.test.ts src/main/runtime/rpc/terminal-output-frame-chunks-equivalence.test.ts -``` - -Results initially on `79ec57d04`, then rerun after rebasing through `974447175`: 3/3, 1/1, 2/2, 4/4, and 3/3 selected SSH seam tests passed respectively; the three newly relevant parking files passed 39/39.

Coordinator routing defaults on and can be disabled per build with `VITE_DIRECT_SSH_RECONNECT_COORDINATOR=false` or per renderer session with `orca.directSshReconnectCoordinator.enabled=false`; the fallback retains host/authority fencing, atomic terminal recovery, and bounded preparation. - -Deterministic validation on the final rebased implementation passed all 42 changed unit suites (1,960 tests), including the 11-file direct-SSH terminal gate (637 tests), the 11-file renderer provider/transport gate (763 tests), and the 12-file main/preload/runtime/shared authority gate (513 tests), plus full typecheck, changed-code quality, reliability-gate and max-lines checks, `git diff --check`, and an Electron E2E-mode build. The authority gate proves retained SSH connection and detected-port payload admission is wired into native preload and runtime-client/environment production routes.

Direct SSH registers its own wake input and must not call or absorb that scheduler; one OS event may wake both ownership domains, but each exact pane finalizes at most once. -- #10986 correctly routes an exact worktree by its own host in multi-host projects. Direct reconnect reuses that worktree-specific precedence only after rejecting any contradictory provenance; it never falls back to project-wide repo ambiguity or focused-runtime ownership. -- #10129 makes capable paired-runtime reasonless close fail closed. Direct SSH cleanup clears transient bindings only: it never emits `session.tabs.close`, retires a tab, or kills a provider PTY. -- #10799 confirms runtime project setup must refuse `ssh:` rather than act locally. The desktop direct-SSH handler likewise rejects `runtime:` hosts, and runtime-owned SSH rows remain under runtime authority. -- #11016 parks terminal views without clearing their PTYs. Direct SSH binding cleanup does not invoke parking, close, or layout mutation; the mounted view observes the atomic PTY-state patch independently. -- #10818 routes folder automation through `getKnownWorktreeById` and ambiguity-aware `getFolderWorkspaceConnectionId`, and publishes agent tabs only after binding the spawned PTY. Direct reconnect uses the same effective folder connection as provenance, rejects mixed ownership, preserves agent state, and never treats an adopted PTY as live under a newer authority without matching binding evidence. -- #10891 preserves legacy first-wins semantics while indexing ID-only hydration lookups. Direct reconnect must not treat `buildWorktreeByIdIndex` as ownership proof: target hydration and reattach resolve a host-qualified worktree first and fail closed on duplicate or contradictory ownership. -- #10915 changes runtime output-frame chunking without changing PTY binding, authority, close intent, or hydration ownership. Direct reconnect does not reset output sequence state or reinterpret runtime frames. - -## Invariants - -### Authoritative provider authority - -1. Main is the sole issuer of `SshProviderEpoch` and `connectionGeneration`. Renderer never increments, orders, parses, or synthesizes either value. -2. Direct SSH state is normalized to `providerEpoch: SshProviderEpoch | null` plus `connectionGeneration?: number`. Main-originated direct SSH state always carries a valid pair. `null` or a missing generation means unknown authority, not zero and not a renderer fallback. -3. A single `rotateSshProviderAuthority(targetId)` helper advances both values atomically before every provider-invalidating transition: new connect ownership, transport replacement or loss, relay/multiplexer replacement or loss, provider disposal, target readoption/reassignment, and permanent target removal. No producer may rotate or publish only one component. -4. `connectionGeneration` remains the existing SSH mutation expectation. Expanding its rotation set closes relay-only mutation races. Provider/reconnect operations compare the full `(providerEpoch, connectionGeneration)` pair; this is the formal composition rule, not two independent clocks. -5. Main registers the provider serving the new pair before broadcasting `connected`. A broadcast-first transition is invalid because it can start a preparation against an unregistered provider with no guaranteed self-heal event. -6. Renderer partial state writers are patches. They preserve both main authority fields and cannot author a `connected` state with a new value. -7. Every boundary that decides equality, copies state, admits retained state, preloads state, reconciles state, or republishes state must preserve both fields. This inventory includes `sshConnectionStatesEqual`, `admitSshConnectionState` and its byte/range checks, public-state projection, `ssh:getState`, `ssh:state-changed`, startup reconnect, runtime-client retained payloads, renderer/runtime SSH state stores, web-file mutation reads, and all fixtures/builders. Allowlisted clones must name both fields; equality treats either field changing as significant. -8. A recovery operation captures one exact `DirectSshAuthority = (targetId, providerEpoch, connectionGeneration)`. Equality is the only permitted authority operation. -9. If a connected event lacks either component, the renderer performs one bounded `ssh:getState` reconciliation with a per-target arrival watermark. The reply may fill authority only if no newer push event arrived and the stored event/status still matches the initiating event; it cannot transition status or resurrect an older `connected` state. If authority remains unknown, authoritative preparation, retry, sync, and snapshot mutation fail closed with `authority-unknown`; disconnect cleanup remains allowed. -10. After every await and inside every authoritative store updater, current state must still name the same connected target and exact authority pair. -11. Supersession is determined by coordinator arrival order and exact equality, never numeric ordering. -12. On any authority change, before new preparation admission, cancel the target's queued work, locally settle obsolete waiter leases, send exactly one cancellation for every affected in-flight provider request ID, mark all late results stale, and retain main-side post-await fences. Terminal finalization for the new authority does not wait for old relay work. -13. Exhausting one target's per-session generation counter rolls the process generation scope and revokes every direct SSH target, not only the target that exhausted its counter. Main invalidates every cached authority and aborts every registered provider request from the old scope before any target can publish or admit work under the new scope. - -### Host-qualified ownership - -1. Direct reconnect work owns only `toSshExecutionHostId(targetId)`. -2. Every coordinator detected-worktree provider invocation carries `(repoId, executionHostId, expectedAuthority, providerRequestId)`. Each renderer consumer separately owns a `waiterLeaseId`; a lease ID never crosses IPC or names provider work. -3. Main resolves a repo by the complete `(repo.id, executionHostId)` identity only after validating all present repo provenance. `executionHostId` and legacy `connectionId` must agree when both are present; a catalog row for which either source names the requested host while the other names another SSH, local, or runtime host makes the host catalog non-authoritative. Zero, contradictory, or multiple matches fail closed. Main never uses explicit-field precedence to hide a contradiction and never falls back to first-match `getRepo(repoId)` for a host-qualified request. -4. A local host request can select only a local repo. A direct SSH host request can select only the matching target/provider. A runtime host is rejected by the desktop handler and must use the existing runtime RPC route. -5. A successful response uses a local or direct-SSH discriminant. The direct-SSH variant cannot be constructed without the resolved execution host and full authority pair. Renderer validates the wire discriminant and rejects a mismatch before any use. -6. Runtime-owned or runtime-transported worktrees remain under the runtime environment scheduler, including SSH execution hosts whose `runtimeOwnerEnvironmentId` names a HUB. -7. Raw repo IDs, paths, UI focus, and unqualified legacy metadata are not ownership evidence. Pre-catalog scope resolution uses explicit worktree/repo provenance and `getExplicitRuntimeEnvironmentIdForWorktree`; it must not use the focused-runtime fallbacks in `getExecutionHostIdForWorktree` or `getRuntimeEnvironmentIdForWorktree`. `runtime:unresolved-owner` and focus-only results are ambiguous, not another host's. Unknown ownership is diagnostic and retryable, but never authoritatively replaced or deleted. -8. All present provenance must agree. Explicit worktree ownership takes precedence only after agreement is proven; repo-derived ownership is a fallback only when explicit worktree ownership is absent. A worktree stamped `ssh:B` with repo-derived `ssh:A`, or any direct-SSH row with an explicit runtime owner, is `contradictory-owner` and is preserved without refresh, merge, retry, or pruning. - -### Merge fencing - -1. Provider results are immutable until all host and authority checks pass. -2. Main revalidates the request host, provider instance, and exact authority after the provider await and before: - - remembering worktree roots; - - pruning persisted lineage; - - stamping or backfilling worktree metadata; or - - returning an authoritative result. -3. Renderer revalidates immediately after the preload/runtime await and before any use of the result, including: - - `routeListingBranchSwitchesThroughGitIdentity`; - - hosted-review sanitation; - - `updateWorktreeGitIdentity`; - - `buildWorktreePurgeState`; - - `worktreesByRepo` or `detectedWorktreesByRepo` merges; and - - best-effort lineage refresh. -4. Host-scoped catalog and lineage snapshots are revalidated before their sole renderer merge. -5. A remote-workspace token and snapshot revision are revalidated after hydration and immediately before session merge/publish. The merge also preserves any terminal-recovery revision newer than the snapshot operation. -6. Stale, superseded, timed-out, and canceled results perform zero authoritative mutations and are not logged as operational errors. - -### Terminal state - -The disconnect action preserves the current call-site predicate: a tab is affected only when `tab.ptyId != null`. A tab without a `ptyId` remains byte-identical even if it has `pendingActivationSpawn` or an inconsistent auxiliary PTY index. - -For each affected tab, the atomic action must: - -- set `tab.ptyId` to `null`; -- empty its `ptyIdsByTabId` entry; -- consume `pendingActivationSpawn`; -- remove pending Codex restart and restart-notice entries for the cleared live PTY; -- preserve `lastKnownRelayPtyIdByTabId` for relay-grace reattach and the `#9911` orphan-safety invariant; and -- leave layouts, deferred SSH sessions, pending reconnect IDs, suppression/shutdown guards, tab IDs, titles, generations, and agent state unchanged. - -The action must not bump activity, sort worktrees, or persist worktree metadata. A repeat after all qualified bindings are clear returns the original store state. -It also must not emit `session.tabs.close`, `session.tabs.closeLifecycle`, provider shutdown, or process signals. Binding loss is not close intent, tab retirement, or proof that a PTY died. - -Reconnect finalization must: - -- use `shouldRetryPaneSpawnOnSshReconnect`; -- include exact direct SSH Git-worktree and folder-workspace keys; -- run synchronously before catalog or provider awaits; -- treat a non-null `ptyId` as live only when transient binding provenance names the current authority and the current tab-wide spawn/reattach attempt has established live authority; -- clear stale binding evidence from a missed disconnect or prior authority before testing retry eligibility; -- keep at most one tab-wide retry attempt in flight per tab and authority; -- join renderer pending-spawn promises only for the same retry attempt; authority or tab-generation advance starts independently, and a late obsolete fresh PTY is rejected and retired; -- accept a spawn or reattach acknowledgement only when its attempt, authority, tab generation, target-qualified PTY, and committed PTY index all match; the first split success establishes the tab fallback and a live continuation lease, and later or post-success-mounted siblings capture and commit through that exact lease without replacing the fallback; -- admit a reattach identity before publishing renderer PTY handlers; revalidate the captured lease after every asynchronous SSH preparation wait and, after the synchronous already-exited delivery case, before error or launch-metadata publication, deferred-state mutation, binding cleanup, or replacement spawn; drop stale owned handlers without killing the durable PTY a current lease may adopt; -- settle retirement of a newly created session-expired fallback when admission rejects it, including after transport destruction, and surface shutdown refusal as unknown, without killing a rejected reattach or cold restore that another current lease may adopt; -- preserve the continuation lease if its primary PTY exits while another split leaf from the same attempt is still activating, then promote the late sibling when it commits; -- on an attempt-one sibling failure or timeout, revoke that attempt and rotate the whole tab once; after attempt two is exhausted, retain its continuation lease for siblings already settling while forbidding attempt three; -- when a split pane detaches to a new tab, project the same exact live or pending authority and retry history to both resulting tabs, including a bound-plus-unbound split or an all-null continuation gap before any leaf binds; the detached null-PTY tab remains activation-pending, and a rejected acknowledgement or detach returns the original relevant maps unchanged; -- permit a tab hydrated, newly discovered, or left unbound after a failed spawn to receive a bounded same-authority corrective bump; -- update all affected workspace buckets in one Zustand publication; and -- leave preparation-only requests, nonqualifying tabs, and every other host unchanged. - -The coordinator keeps separate authority-scoped pending-attempt state and successful-binding state, not a set of bump attempts and not a cached preparation outcome. The live binding carries the exact attempt ID as a continuation lease for every split leaf in that tab generation. A healthy live binding, including a bounded empty-primary activation gap, suppresses correction; an unresolved tab is reconsidered on wake, snapshot completion, and preparation completion with at most one tab-wide attempt in flight. One authority chain preserves its complete attempt history and has a hard limit of two automatic attempts. A timeout taking longer than the former rolling 30-second window cannot age out the first attempt and start a third automatic attempt; later wake, snapshot, and preparation triggers remain exhausted until authority replacement rotates pending, binding, and history state. - -## Design - -### 1. Composed provider authority and host-qualified IPC - -Add `SshProviderEpoch` to the shared SSH types and compose it with the existing main-owned connection generation in `src/main/ssh/ssh-provider-authority.ts`. This module owns atomic rotation and delegates generation storage/assertion to `ssh-connection-generation.ts`; it does not introduce an independently advancing clock. - -The direct SSH state boundary becomes: - -```ts -type SshProviderEpoch = string & { readonly __sshProviderEpoch: unique symbol } -type ProviderRequestId = string & { readonly __providerRequestId: unique symbol } -type WaiterLeaseId = string & { readonly __waiterLeaseId: unique symbol } -type SshExecutionHostId = Extract - -type DirectSshStateAuthority = { - providerEpoch: SshProviderEpoch | null - connectionGeneration?: number -} - -type DirectSshAuthority = { - targetId: string - providerEpoch: SshProviderEpoch - connectionGeneration: number -} -``` - -The epoch wire value is a bounded opaque string. Branding is compile-time only. Main state broadcasts and `ssh:getState` include the pair; renderer state stores it without interpretation. `rotateSshProviderAuthority` is the only transition writer and `assertSshMutationExpectation` observes the generation advanced by that same call. - -Extend preload/main detected-worktree APIs: - -```ts -type LocalDetectedWorktreeRequest = { - providerRequestId: ProviderRequestId - repoId: string - executionHostId: typeof LOCAL_EXECUTION_HOST_ID -} - -type DirectSshDetectedWorktreeRequest = { - providerRequestId: ProviderRequestId - repoId: string - executionHostId: SshExecutionHostId - expectedAuthority: DirectSshAuthority -} - -type ListDetectedWorktreesArgs = LocalDetectedWorktreeRequest | DirectSshDetectedWorktreeRequest - -type AuthoritativeHost = - | { - kind: 'local' - executionHostId: typeof LOCAL_EXECUTION_HOST_ID - } - | ({ - kind: 'direct-ssh' - executionHostId: SshExecutionHostId - } & DirectSshAuthority) - -type HostQualifiedDetectedWorktreeResult = - | { - status: 'complete' | 'non-authoritative' - providerRequestId: ProviderRequestId - repoId: string - authority: AuthoritativeHost - result: DetectedWorktreeListResult - } - | { - providerRequestId: ProviderRequestId - executionHostId: ExecutionHostId - status: - | 'canceled' - | 'timed-out' - | 'stale' - | 'ambiguous-owner' - | 'authority-unknown' - | 'rejected' - } -``` - -`DirectSshDetectedWorktreeRequest` requires the full pair as one `expectedAuthority`; local requests cannot carry it. Construction and runtime admission also require `executionHostId === toSshExecutionHostId(expectedAuthority.targetId)`. Every data-bearing direct-SSH response, including `non-authoritative` metadata fallback, is therefore impossible to construct without both fields. Runtime validation rejects decoded SSH data payloads missing either component even if an untyped or older boundary fabricates one. Main owns the 30-second provider deadline; no renderer-supplied timeout can extend it. The desktop handler rejects runtime hosts. Keep an explicitly unqualified legacy overload only for existing callers during migration; it fails closed when more than one host owns the repo ID and is removed after all callers pass a host. - -Main selects the repo and provider before starting work, captures the provider object and full authority, and checks all three again after `provider.listWorktrees`. A host-qualified SSH response cannot be restamped by renderer as another host. - -Use host-qualified lineage ownership as well: - -```ts -type ListDesktopLineageForHostArgs = - | { executionHostId: typeof LOCAL_EXECUTION_HOST_ID } - | { - executionHostId: SshExecutionHostId - expectedAuthority: DirectSshAuthority - } - -type HostLineageSnapshot = - | { - authoritative: true - authority: AuthoritativeHost - worktreeLineageById: Record - workspaceLineageByChildKey: Record - } - | { - authoritative: false - executionHostId: ExecutionHostId - reason: 'ambiguous-owner' | 'authority-unknown' | 'stale' | 'unavailable' - } -``` - -Main filters the snapshot to the requested host. Renderer replaces only an authoritative discriminated host scope; malformed SSH authority is rejected before merge. Direct SSH preparation replaces the current bare `fetchWorktreeLineage()` call with this host-qualified API; it does not substitute `{ forceLocalOwner: true }`. - -Main destructive pruning must use qualified repo/worktree ownership. An existing row `meta.hostId` must agree with the resolved repo host in every case. Only an absent legacy host may be inferred when exactly one stored repo owns the repo ID, preserving today's path-reuse cleanup. When multiple hosts can own the ID, pruning requires row `meta.hostId`; absence or conflict makes the result non-authoritative and preserves the row. Authoritative scans backfill absent `meta.hostId` so legacy rows self-heal. Never use repo-ID-prefix pruning across hosts. - -The shared renderer store and web preload retain their existing non-direct-SSH callers. Preserve the legacy/runtime overload and its argument/echo shape in `web-preload-api.ts`, but do not broaden the web client into direct-SSH coordination: paired web clients cannot subscribe to desktop `ssh:state-changed`, so the proposed total direct-SSH web break is not reachable. Shared API type changes still receive compatibility tests so a runtime-routed web read is not rejected merely because the wrapper dropped its requested host. - -### 2. Exact direct SSH target scope - -Add `src/renderer/src/lib/direct-ssh-target-scope.ts`: - -```ts -type DirectSshGitRepoRef = { - repoId: string - executionHostId: SshExecutionHostId -} - -type DirectSshTargetScope = { - catalogRevision: number - gitRepos: DirectSshGitRepoRef[] - gitWorktreeIds: Set - terminalWorkspaceKeys: Set - lineageWorkspaceKeys: Set - ambiguousOwnerCount: number - contradictoryOwnerCount: number -} -``` - -Resolution rules: - -- Build the expected host with `toSshExecutionHostId(targetId)`. -- Resolve repos by `(repo.id, executionHostId)`. -- Collect explicit worktree host, exact repo-derived host, projected runtime owner, and any restored host evidence before selecting a row. -- If two present sources disagree, classify the row as `contradictory-owner`; preserve it and exclude it from refresh, merge, terminal retry, snapshot projection, and pruning. -- When explicit worktree host is present and no source contradicts it, require it to equal the expected host. Use exact repo-derived ownership only when the explicit worktree host is absent. -- Require `getExplicitRuntimeEnvironmentIdForWorktree` to be `null`; an explicit runtime owner contradicts direct SSH even when another source names the expected SSH host. -- Do not use focused-runtime fallback ownership during pre-catalog reconnect. Focus-only local/runtime results and `runtime:unresolved-owner` are ambiguous. -- Do not use `buildWorktreeByIdIndex`, raw `getKnownWorktreeById`, or another first-wins ID-only lookup as authoritative direct-SSH ownership. Hydration and reattach use an exact host-qualified row or fail closed. -- Accept a folder workspace only when its effective connection is exactly `targetId`, its execution host is expected, runtime owner is `null`, and all candidate repo/group/workspace provenance agrees. -- Treat mixed/conflicting folder provenance as contradictory; duplicate same-host owners and unresolved legacy rows are ambiguous/unowned. -- A parsed live app-SSH PTY can recover a stale-catalog terminal only when no explicit other-host or runtime ownership contradicts it. - -Git refresh uses `gitRepos`; terminal clear/retry uses raw Git IDs and folder keys from `terminalWorkspaceKeys`; unified lineage uses `worktree:` and folder keys from `lineageWorkspaceKeys`; snapshot projection uses `gitWorktreeIds`. Folder workspaces never enter the path-based remote-workspace schema. - -When exact repo rows are missing, use a new host-scoped desktop catalog read rather than focused `fetchRepos()` or an all-desktop refresh: - -```ts -listReposForExecutionHost({ - executionHostId, - expectedAuthority -}) -``` - -Main validates explicit and legacy ownership before producing the host snapshot. A row with contradictory `executionHostId` and `connectionId` cannot be filtered into one host by precedence or silently omitted from the other; a contradiction touching the requested host returns a non-authoritative catalog with no rows. - -The renderer merges the immutable response into only that host scope after a full-authority fence. This action owns a per-host catalog revision and in-flight entry; it does not share `reposFetchGeneration` with focused-runtime or all-host fetches. Thus a concurrent runtime-focused catalog refresh cannot silently supersede direct SSH hydration. -Its authoritative response uses the same `AuthoritativeHost` discriminant as detected worktrees and lineage, so direct-SSH catalog data also requires the complete pair. - -### 3. Bounded and cancelable direct SSH provider scheduler - -Add `src/renderer/src/hooks/direct-ssh-worktree-refresh-scheduler.ts`. It is owned by the `useIpcEvents` effect and used only for direct SSH coordinator scans. - -Required behavior: - -- at most `DIRECT_SSH_WORKTREE_SCAN_CONCURRENCY` (five) locally unsettled coordinator-owned detected-worktree requests in flight; -- owner-aware round-robin selection by target, with repos submitted incrementally rather than flattening one target into a global FIFO; -- no fixed collection window for an idle singleton request; -- an input key of `(repoId, executionHostId, providerEpoch, connectionGeneration, catalogRevision, authoritative requirement)`; -- join only a currently running logical repo task with the exact same key; -- retain the logical key across a first `retrying` timeout and delete it only on a terminal outcome; -- explicit `complete`, `non-authoritative`, `timed-out`, `cancel-budget-exhausted`, `canceled`, `stale`, and `rejected` outcomes; and -- no console error or degraded count for expected cancellation/supersession. - -Each provider invocation has the existing 30-second main-owned deadline. Main creates an `AbortController`, passes its signal to `SshGitProvider.listWorktrees`, and therefore reaches the multiplexer `rpc.cancel` path on timeout. A transient first timeout changes the repo task to `retrying` and requeues it once at the tail of that target's round-robin lane if the full authority remains current. That repo task promise does not settle, and target lineage/token creation does not start, until the retry completes, reaches its second timeout, is invalidated, or retry admission terminates as `cancel-budget-exhausted`. Add cancellation IPC keyed only by `providerRequestId`; authority advance, target invalidation, last-waiter release, and effect teardown abort matching main requests. Queued requests have no provider request ID and cancel without IPC. - -The first timed-out provider invocation and its leases settle before retry admission. The logical repo task remains pending and acquires a fresh provider request ID plus fresh waiter leases for the retry; preparation waiters never reuse an already-canceled provider identity. - -Cancellation uses waiter leases: - -- `waiterLeaseId` and `providerRequestId` are different opaque types generated independently. A provider request ID names one underlying preload/main/provider invocation; every consumer of that shared invocation receives its own renderer-only waiter lease ID. -- The shared detected-worktree coalescer, not the direct coordinator alone, owns the lease registry so sidebar/filesystem consumers also keep a joined provider invocation alive. -- Canceling or superseding one lease settles only that consumer. It does not call cancellation IPC while any other lease remains. -- Releasing the last lease sends exactly one cancellation IPC carrying the provider request ID and captured host/authority. Main never receives, stores, or accepts waiter lease IDs. -- Main aborts the provider request when that cancellation identity matches or when provider authority is invalidated. It does not reconstruct waiter ownership. -- Local cancellation returns after waiter settlement and, for the last lease, main provider-promise settlement. `ssh-channel-multiplexer` rejects its local provider promise when it sends fire-and-forget `rpc.cancel`; no relay response is awaited. -- The scheduler releases the local slot when the underlying provider promise settles locally. The original relay handler may observe abort later, so this metric is not a hard relay-process concurrency claim. -- Track every locally canceled underlying call as conservative cancel debt on its provider instance. Admission requires `locallyUnsettled + cancelDebt <= DIRECT_SSH_PROVIDER_START_BUDGET` (seven), so five canceled calls permit at most two replacements and repeated cancel/retry cannot create unbounded client-originated work. Debt is not cleared by elapsed time or local promise settlement because neither proves relay completion; it clears only when the owning provider/multiplexer is disposed or replaced. A logical task denied admission by this budget settles terminally as `cancel-budget-exhausted`; it never waits for provider replacement and never leaves the preparation barrier pending indefinitely. A hard bound on handlers surviving disposal is impossible without a relay acknowledgement, so telemetry states this as a seven-start per-provider budget rather than a total remote-process guarantee. - -```ts -type DetectedWorktreeRefreshLease = { - waiterLeaseId: WaiterLeaseId - providerRequestId: ProviderRequestId - result: Promise - release(reason: 'superseded' | 'invalidated' | 'stopped'): void -} -``` - -Each lease has its own settlement promise. Normal provider settlement resolves all remaining leases and removes the provider entry automatically; early `release` is idempotent and settles only that lease as canceled. - -Every other preparation await is bounded too: host-scoped catalog and lineage IPC use five-second deadlines, workspace hydration retains its ten-second deadline, and existing remote-workspace RPC deadlines remain in force. Catalog and lineage waiters accept coordinator cancellation; because their main work does not launch a provider process, a late reply is discarded by the renderer fence rather than holding a scheduler slot. - -The existing runtime project scheduler keeps its own five-worker pool, 250 ms debounce, and 5-second minimum interval. Sidebar and filesystem-event refreshes remain unchanged. Cross-subsystem isolation is intentional; the coordinator's bound is not presented as a renderer-wide bound. - -Keep the public `detectedWorktreeRefreshKey` shape unchanged. Its in-flight entry records a provider invocation identity and a lease map; direct-SSH authoritative work may join only when host and full authority also match. An incompatible entry under the same public key gets a separate underlying invocation rather than an unsafe join. The coordinator's authority/revision key wraps this coalescer without fragmenting compatible sidebar or filesystem-event sharing. The shared coalescer owns provider request IDs and waiter leases; the coordinator owns authority/revision fencing, retry state, and scoped metrics. - -### 4. Per-target reconnect coordinator - -Add `src/renderer/src/hooks/direct-ssh-reconnect-coordinator.ts`, instantiated once in `useIpcEvents`: - -```ts -type DirectSshAuthority = { - targetId: string - providerEpoch: SshProviderEpoch - connectionGeneration: number -} - -type PreparationInput = DirectSshAuthority & { - catalogRevision: number - repoRefs: DirectSshGitRepoRef[] - authorityRequirement: 'required' | 'allow-metadata-fallback' - snapshotRevision?: number - reason: 'reconnect' | 'initial-hydration' | 'workspace-snapshot' | 'wake-refresh' -} - -type DirectSshReconnectCoordinator = { - requestReconnect(authority: DirectSshAuthority): Promise - prepareOnly(input: PreparationInput): Promise - finalizeHydratedTerminals(authority: DirectSshAuthority): number - correctUnboundTerminals(authority: DirectSshAuthority, reason: CorrectionReason): number - replaceAuthority(authority: DirectSshAuthority): void - invalidate(targetId: string): void - stop(): void -} -``` - -There is no global reconnect wave and no authority-long prepared-outcome cache. Transient per-tab pending/live-binding state is separate and exists only to settle or re-arm terminal recovery. - -`replaceAuthority` compares the complete authority tuple. An exact-equal replacement is a no-op: it does not settle leases, clear pending/live terminal state, cancel provider work, or fragment an overlapping preparation. Only a different tuple performs authority replacement. - -#### Reconnect-finalization flow - -```ts -async function requestReconnect(authority) { - if (!isCurrentConnectedAuthority(authority)) return stale() - - // Authority replacement first settles all obsolete local leases and fences their late work. - coordinator.replaceAuthority(authority) - - // A missed disconnect can leave a non-null PTY from the old provider incarnation. - invalidateStaleDirectSshTargetPtyBindings(authority) - - // Terminal-critical and synchronous: no catalog, Git, lineage, or other target can gate it. - const retried = retryDirectSshTargetPanes(authority) - - // Relay flapping never delays terminal recovery, but it does damp full Git preparation. - if (!hasAuthorityBeenStableFor(authority, RELAY_LOST_STABILIZED_MS)) { - scheduleLatestAuthorityPreparation(authority, RELAY_LOST_STABILIZED_MS) - return terminalOnlyOutcome(retried, 'stabilizing') - } - - const input = await capturePreparationInput(authority, 'reconnect') - if (!input.ok) return terminalOnlyOutcome(retried, input.reason) - - const prepared = await prepare(input.value) - if (!prepared.token || !isCurrentConnectedAuthority(authority)) { - return combine(retried, prepared) - } - - // Catch tabs whose exact ownership or hydration became visible during this target's preparation. - const discoveredRetries = correctUnboundTerminals(authority, 'preparation-complete') - void syncRemoteWorkspaceAfterConnect(prepared.token) - return combine(retried + discoveredRetries, prepared) -} -``` - -The first terminal retry is complete before `capturePreparationInput` performs any await. Target B therefore retries even when target A has five slow provider requests. A same-authority duplicate runs bounded correction: healthy live bindings are no-ops, pending attempts are not duplicated, and failed/unbound tabs can re-arm. When workspace hydration completes, `finalizeHydratedTerminals` reruns against the current authority and handles newly hydrated or still-unbound tabs. - -Preparation for each target progresses independently. While authority remains current, it performs its host-scoped lineage read only after every repo task reaches a terminal state: `complete`, `non-authoritative`, final `timed-out`, `cancel-budget-exhausted`, or `rejected`. Authority-wide `canceled`/`stale` returns without lineage or a token. A first retryable timeout is the nonterminal `retrying` state and cannot release lineage, terminal correction, sync, or token creation. The target never waits for another target's repos or lineage. - -When authority rotates again within `RELAY_LOST_STABILIZED_MS` (currently five seconds), replace the delayed preparation with the latest authority and perform terminal finalization immediately. Only the authority that survives the stabilization window starts catalog/Git/lineage work. A same-authority wake during that window coalesces into the pending latest-authority preparation. This is damping, not an epoch-long result cache. - -#### Preparation-only flow - -`prepareOnly` runs catalog/worktree/lineage preparation and returns a token. It never invokes terminal retry and never starts reconnect sync. An unsolicited snapshot uses this mode, then applies that snapshot with the returned token. - -Reconnect and preparation-only requests may share exact overlapping catalog, repo, or lineage promises through ref-counted waiter leases. Superseding one consumer settles only its lease; it does not abort work still owned by another current consumer. They do not share finalization side effects. - -#### Input-scoped deduplication - -Preparation captures concrete inputs: exact authority pair, catalog revision, sorted repo/host refs, authoritative requirement, and snapshot revision when present. Only currently overlapping operations with identical relevant inputs join. - -Completed entries are removed immediately. Consequently: - -- a later same-authority wake rebroadcast runs another bounded refresh; -- a later snapshot revision runs another bounded preparation; -- a newly discovered repo changes the catalog revision/repo fingerprint and cannot join an older scope; -- a snapshot received during reconnect can share the still-running provider reads; and -- the reconnect call chain can pass its completed token directly to sync/apply without a second preparation. - -The token is an operation result, not a coordinator cache entry: - -```ts -type DirectSshPreparationToken = { - authority: DirectSshAuthority - catalogRevision: number - repoFingerprint: string - authorityRequirement: PreparationInput['authorityRequirement'] - snapshotRevision: number | null - outcome: 'complete' | 'degraded' -} - -type SnapshotApplyToken = DirectSshPreparationToken & { - snapshotRevision: number -} -``` - -An unsolicited snapshot passes its revision into `prepareOnly`, so the returned token is already snapshot-bound. Reconnect preparation returns `snapshotRevision: null`; after `remoteWorkspace.get`, sync revalidates authority and creates a `SnapshotApplyToken` by copying the fetched revision onto that token. `applyRemoteWorkspaceSnapshot` accepts only `SnapshotApplyToken` and requires exact revision equality, so it cannot reuse preparation across incompatible snapshots. - -### 5. Fenced worktree, catalog, and lineage merges - -Refactor detected-worktree listing so provider acquisition and store mutation are separate: - -```ts -const listed = await listDetectedWorktreesForRepoCoalesced(request) -if (!isCurrentHostAuthority(request, listed)) return canceled('stale') - -// No code using listed.result may occur above this fence. -return mergeDetectedWorktrees(listed.result, request) -``` - -`mergeDetectedWorktrees` performs the sole renderer mutation for that result. It owns git-identity routing, review-link sanitation, purge state, and both worktree maps in one fenced path. It must not start an unfenced lineage refresh. - -The existing shared coalesced refresh key already includes `executionHostId` and remains unchanged. Add the full authority and concrete input revision only to the coordinator wrapper key. Do not describe host parsing as new key behavior and do not alter cross-subsystem coalescing. - -Host-scoped catalog and lineage functions likewise return immutable results. Each has one merge entry point that revalidates the current exact authority inside the Zustand updater. A stale result produces zero publications. - -Main uses the same pattern around provider work: - -```ts -const authority = resolveExactProvider(args) -const gitWorktrees = await authority.provider.listWorktrees(repo.path, { signal }) -if (!stillOwnsExactProvider(authority, args.expectedAuthority)) return stale() - -return buildAndCommitAuthoritativeResult(authority, gitWorktrees) -``` - -No prune, root-memory update, or metadata backfill occurs before `stillOwnsExactProvider`. - -### 6. Atomic terminal disconnect and retry - -Add terminal-slice actions: - -```ts -clearDirectSshTargetPtyBindings(targetId: string): number -invalidateStaleDirectSshTargetPtyBindings(authority: DirectSshAuthority): number -retryDirectSshTargetPanes(authority: DirectSshAuthority): number -settleDirectSshPaneRetry(result: DirectSshPaneRetryResult): void -``` - -Put pure projections in `src/renderer/src/store/slices/direct-ssh-terminal-recovery.ts`. - -`clearDirectSshTargetPtyBindings` traverses `tabsByWorktree` once, selects exact target scope, then applies the `tab.ptyId != null` predicate. For every affected tab the same atomic projection sets `tab.ptyId` to `null`, empties its `ptyIdsByTabId` entry, consumes `pendingActivationSpawn`, and removes pending Codex restart/restart-notice entries for the cleared live PTY. It preserves `lastKnownRelayPtyIdByTabId`, layouts, deferred SSH sessions, pending reconnect IDs, shutdown/suppression state, IDs, titles, generations, and agent state. It lazily clones only changed workspace arrays and maps, commits one patch, and triggers no activity, sorting, or metadata persistence. Tabs without a current `ptyId`, including those with `pendingActivationSpawn`, are untouched. - -`invalidateStaleDirectSshTargetPtyBindings` validates the authority inside the updater and applies that complete atomic projection to a non-null `ptyId` when its transient `ptyAuthorityByTabId` does not equal the current authority. Snapshot-imported or legacy bindings without current-authority provenance are wake hints, not live bindings. - -`retryDirectSshTargetPanes` validates the exact authority inside the updater, resolves scope from that same state snapshot, applies `shouldRetryPaneSpawnOnSshReconnect` plus stale-binding evidence, excludes only current live-success and pending-attempt tab IDs, and commits one `tabsByWorktree` patch. It records a unique tab-wide attempt outside the success ledger. `settleDirectSshPaneRetry` records current-authority success only after a live PTY binding is committed. A failed or timed-out first attempt rotates the tab once; an exhausted second attempt retains continuation authority for sibling callbacks but cannot start a third attempt. - -`clearTabPtyId` keeps genuine single-PTY exit semantics, but split recovery adds two exact-authority projections: promote an already-bound surviving PTY under the same lease, or preserve the lease and activation suppression across an empty-primary gap until a same-attempt sibling commits or settles. `syncPaneDetachPtyOwnership` likewise projects one current split lease and history to both resulting tabs without spawning, exiting, or changing authority, even when the pending attempt has not produced its first PTY. A pane mounted after the first sibling succeeds captures the retained live lease; every spawn callback rechecks the full authority pair and retires a stale provider PTY. Permanent target removal continues through `src/renderer/src/store/slices/ssh-target-cleanup.ts`, whose deletion of last-known and deferred liveness is invalid for a reconnectable disconnect. - -`applySshConnectionStateChange` receives an explicit origin and becomes orchestration: - -```ts -type SshStateApplyOrigin = 'push' | 'initial-hydration' - -const applySshConnectionStateChange = (targetId, state, origin: SshStateApplyOrigin) => { - const previous = getSshConnectionState(targetId) - setSshConnectionState(targetId, state) - - if (isTerminalFailure(state.status)) { - coordinator.invalidate(targetId) - clearRemoteDetectedAgents(targetId) - clearPortForwards(targetId) - setDetectedPorts(targetId, []) - clearDirectSshTargetPtyBindings(targetId) - return - } - - if (state.status === 'connected') { - if (!state.providerEpoch || state.connectionGeneration === undefined) { - void reconcileAuthorityOnce({ - targetId, - initiatingEventWatermark: getStateEventWatermark(targetId), - initiatingState: state, - initiatingOrigin: origin - }).then(applyAuthorityPatchIfStillCurrent) - } else { - const authority = { - targetId, - providerEpoch: state.providerEpoch, - connectionGeneration: state.connectionGeneration - } - - if (origin === 'initial-hydration') { - coordinator.replaceAuthority(authority) - void coordinator.prepareOnly({ - ...authority, - authorityRequirement: 'required', - reason: 'initial-hydration' - }) - } else if ( - previous?.status !== 'connected' || - previous.providerEpoch !== state.providerEpoch || - previous.connectionGeneration !== state.connectionGeneration - ) { - void coordinator.requestReconnect(authority) - } else { - coordinator.correctUnboundTerminals(authority, 'wake-refresh') - void prepareAndSyncWithoutHealthyTerminalRemount({ - ...authority, - reason: 'wake-refresh' - }) - } - } - } -} -``` - -Increment the per-target state-event watermark before applying every push event. `setSshConnectionState` must publish when either authority component changes. Reconciliation may only patch missing authority onto the still-current initiating state; it never enqueues a complete stale state reply. - -The terminal-failure cleanup order remains `clearRemoteDetectedAgents`, `clearPortForwards`, `setDetectedPorts([])`, then atomic PTY binding clear. Preserve the current port-broadcast race defense and detected-agent re-detection behavior. - -An already-connected same-authority rebroadcast is a wake refresh, not a healthy-pane remount. It performs bounded unbound/stale correction, fresh bounded preparation, and sync. Initial hydration always carries `origin: 'initial-hydration'` and uses `prepareOnly`; it is never inferred from the absence of `previous`. A bounded authority reconciliation retains the initiating origin, so filling a retained state's missing pair also cannot become a reconnect transition. Hydrating an already-live state must not remount healthy panes. Workspace session completion invokes `finalizeHydratedTerminals` only for reconnect authorities recorded during that hydration interval, but a failed/unbound attempt remains eligible for later same-authority triggers. - -## Remote-workspace data flows - -### Reconnect sync - -1. Reconnect finalizes qualifying terminals immediately. -2. Its target-scoped preparation returns a token. -3. Before awaiting `remoteWorkspace.get`, `syncRemoteWorkspaceAfterConnect(token)` captures whether the exact target currently has local tabs. This capture-before-await ordering is load-bearing. -4. The function validates the token, obtains the snapshot, and passes the same token to `applyRemoteWorkspaceSnapshot`. -5. Snapshot apply does not prepare again and is preparation-only with respect to coordinator retry; existing snapshot-driven `reconnectPersistedTerminals` behavior remains. -6. For `revision === 0`, mark hydration and publish the current local session only when the pre-await `hasLocalTabs` capture was true. Revalidate authority before upload. Do not recompute that predicate after preparation/hydration, which could overwrite a newer relay snapshot with locally imported state. -7. Snapshot projection and persisted-terminal reconnect receive only host-qualified worktree references from the token's exact target scope. They cannot reset, replace, remove, or reattach sibling SSH, local, WSL, or runtime-owned tabs or their PTY indexes, layouts, active selection, generations, retry state, or live-binding state, even when raw repo/worktree IDs or paths collide. - -### Unsolicited snapshot - -1. Capture current target authority and the incoming snapshot revision. -2. Call `prepareOnly` with those concrete inputs. -3. Wait for existing workspace-session hydration, bounded by the current 10-second deadline. -4. Capture the target terminal-recovery revision and same-ID local tab recovery fields before snapshot projection. -5. Revalidate the token, snapshot revision, arrival order, and recovery revision immediately before merge. If recovery advanced, rebase the projection on the latest local recovery fields rather than applying the stale captured copy. -6. Apply once as preparation-only. For a same-ID tab, preserve any newer local `generation`, pending attempt, successful current-authority binding, and terminal-recovery revision. Remote `generation` is not comparable across clients and cannot overwrite a local retry. Imported `ptyId`/pending reconnect data is a wake hint until `reconnectPersistedTerminals` settles and current-authority binding provenance is recorded. -7. Run the target-scoped, host-qualified `reconnectPersistedTerminals`, then `finalizeHydratedTerminals` for a reconnect authority. A failed reattach clears pending state and re-arms correction; a successful exact reattach atomically retires its pending attempt and records the current binding without an extra bump. -8. If path resolution still reports unknown worktrees, record a degraded result; do not loop unboundedly. - -A later same-authority snapshot always receives a new preparation attempt after earlier work completed. This preserves convergence when another client creates a worktree while the connection stays live. - -Remote snapshot identity is repo-qualified where the schema provides repo identity: resolve by `(executionHostId, repoId, normalizedPath)` and fail closed on ambiguity. For legacy path-only entries, retain the existing resolver only when the path has exactly one candidate in the exact target scope. Two worktrees at the same absolute host path were not proven producible, so this is a robustness invariant rather than a claim that current storage necessarily creates that collision. - -The existing `buildWorktreeByIdIndex` and `reconnectPersistedTerminals` path retains first-wins ID-only compatibility for its current callers. Direct-SSH snapshot apply must pass host-qualified worktree refs through a dedicated overload or pre-resolved map; it cannot hand raw IDs back to an ID-only lookup and recover authority afterward. - -## Failure handling - -- **Unknown authority:** reconcile once behind the per-target arrival watermark; then fail closed with a retryable diagnostic. Do not use a renderer counter or apply the reply's status. -- **Catalog timeout/failure:** retain cached exact-owner scope, record degradation, and continue target preparation and already-completed terminal recovery. -- **One repo is non-authoritative:** keep its safe metadata fallback separate from operational failure and do not authoritatively delete rows. -- **One repo times out:** the provider invocation settles locally and sends best-effort cancel. On the first retryable timeout, keep the logical repo task and target preparation barrier pending in `retrying`, then requeue once at the target lane tail. A second timeout is final and degrades the repo. If current-provider cancel debt denies retry admission, settle the logical task as terminal `cancel-budget-exhausted`; this releases one degraded preparation outcome rather than an early-success token or an indefinite wait. None of these states blocks another target's terminal retry. -- **One repo rejects:** locally settle it without retry unless classified by the existing narrow transient predicate; operational rejection remains distinct from timeout and non-authoritative data. -- **Lineage timeout/failure:** preserve current lineage, mark target preparation degraded, and continue sync with exact cached worktree scope. -- **Authority advance or target invalidation:** synchronously cancel queued work, settle obsolete local waiter leases, send exactly one cancellation for every affected in-flight provider request ID, rotate renderer in-flight inputs and terminal-attempt state, and reject late results at both main and renderer fences. The new authority begins terminal finalization without waiting for relay acknowledgement. -- **Relay flapping:** finalize terminals for every new authority, but replace/defer full preparation until the latest authority survives `RELAY_LOST_STABILIZED_MS`. -- **Missed disconnect/stale binding:** clear only PTY bindings whose transient binding authority is absent or old, retain last-known relay identifiers, then retry under the new authority. -- **Failed terminal spawn/reattach:** settle the attempt as failed, remove it from pending/success state, and allow rate-limited correction on later preparation, hydration, snapshot, or wake triggers. -- **Workspace hydration timeout:** set existing per-target sync error; do not undo terminal or worktree recovery. Snapshot merge never replaces a newer local recovery revision. -- **Coordinator stop:** cancel queued work, locally settle every waiter, send best-effort aborts for unshared provider calls, and return without waiting for relay acknowledgement. Effect cleanup stops coordinator after subscriptions and before disposing its dedicated scheduler. -- **Unknown owner:** preserve state, count it, and retry on later host-qualified catalog input. -- **Contradictory owner:** preserve state, report the conflicting provenance classes without identifiers, and do not retry or mutate that row until a later catalog revision changes the evidence. - -No failure path falls back to unbounded `Promise.all`. - -## Observability - -Emit one aggregate diagnostic per target operation, not per global wave and not per repo/tab. Use `[direct-ssh-reconnect]` for reconnect finalization and `[direct-ssh-prepare]` for preparation-only work. - -Fields: - -- mode and reason; -- terminal panes retried, stale bindings cleared, successful corrections, and terminal-finalization duration; -- catalog outcome and duration; -- repo tasks completed, non-authoritative, retrying, final timed-out, cancel-budget-exhausted, canceled, stale, and rejected; -- direct-scheduler queue-wait and provider-execution duration distributions; -- timeout retry count, local waiter settlements, cancel debt, and replacement admissions delayed by cancel debt; -- peak locally unsettled coordinator-owned detected-worktree concurrency and estimated late-work allowance; -- lineage outcome; -- Git-worktree, folder-workspace, ambiguous-owner, and contradictory-owner counts; -- overlapping request joins; -- authority rotations observed and preparations damped during flapping; -- total target-operation duration. - -Expected supersession/cancellation is debug-level and does not increment degraded/error metrics. Timeout is separate from queue wait and operational rejection. `fetchWorktrees === false` is not used as a failure proxy; the new discriminated result preserves non-authoritative versus rejected outcomes. - -Do not log target IDs, repo IDs, paths, labels, hosts, usernames, credential errors, snapshot content, raw request IDs, or terminal output. A stable per-session opaque target alias may correlate concurrent aggregate events and is discarded at process exit. - -The product event deliberately omits terminal correction failure/re-arm counts, concurrent non-coordinator call counts, and arrival-order discard counts because this implementation has no truthful production observation for them. It does not populate unobserved fields with constant zeroes. - -Typed product telemetry is implemented with one strict identifier-free aggregate event per target operation. Queue and provider percentiles are derived from that operation's real scheduler samples. The seven-day dogfood dashboard/query is operational follow-up outside this repository; this PR does not claim a dashboard artifact. Schema tests reject identifiers and keep queue wait, execution, timeout, operational rejection, cancellation, and stale results distinct. - -The concurrency metric is explicitly `coordinator_owned_direct_ssh_detected_worktree_concurrency`. It measures locally unsettled provider promises and says nothing about runtime lineage RPCs, sidebar's eight-worker pool, filesystem-event calls, catalog/lineage IPC, total application provider concurrency, non-coordinator same-connection calls, or relay handlers finishing after local cancel. - -## Tests - -This implementation registers the worktree scan-count, host/authority, timeout-barrier, and no-cross-host mutation oracles in the existing `git-worktree.refresh-event-semantics` gate. It extends `terminal-provider.ssh-remote-reattach-contract` for direct-SSH binding clear/retry, hydration, folder workspace, paired-close non-interference, and #8255 wake isolation. A new reliability gate is unnecessary because those existing gates own the lifecycle contracts. - -### Main/preload host and authority contract - -- Preload forwards `repoId`, `executionHostId`, the complete expected authority, and `providerRequestId` unchanged; main owns the deadline and never receives `waiterLeaseId`. -- Renderer host intent across local, direct SSH A/B, and runtime-alias catalog rows routes to the exact provider. Fabricated duplicate main-store rows still fail closed as defense in depth. -- Desktop main rejects a runtime execution host. -- Zero or multiple same-host matches fail closed; unqualified legacy calls fail closed when ownership is ambiguous. -- Compile-time fixtures cannot construct a direct-SSH `complete` result or `authoritative: true` lineage snapshot without both authority fields. Runtime admission rejects malformed wire values that omit either field. Local authoritative variants carry neither SSH field. -- A response echoes exact host and complete authority; renderer rejects any host, target, epoch, generation, provider request, or discriminant mismatch. -- Relay loss/replacement, transport loss/replacement, provider disposal, target readoption, and permanent removal rotate epoch and generation in one helper. -- A per-target generation counter exhaustion rolls the process generation scope, revokes every target's old authority and mutation token, and aborts every old-scope provider request before new-scope admission. -- Relay-only replacement rejects both old reconnect/provider work and an old `SshMutationExpectation`. -- A fresh `connected` authority is not broadcast until its provider is registered. -- An old provider result after any rotation performs no root-memory, lineage-prune, or metadata-backfill mutation. -- Cancellation and timeout reach the provider `AbortSignal` and multiplexer `rpc.cancel`. -- Duplicate repo IDs never trigger cross-host repo-prefix lineage pruning. -- Legacy lineage prunes under a unique repo owner, ambiguous legacy rows are preserved, and an authoritative scan backfills `meta.hostId`. -- `sshConnectionStatesEqual`, retained-payload admission, public projection, preload push/get, startup reconnect, runtime retained/client payloads, renderer/runtime stores, and state builders preserve both authority fields. -- Main-originated broadcasts always publish the complete authority pair. Malformed epoch-only or generation-only retained inputs are rejected; compatibility push/get inputs can only remain `authority-unknown` for bounded reconciliation and perform no authoritative mutation. One valid pair change publishes once and an exact duplicate is a no-op. -- Retained-state admission accepts a bounded valid epoch, rejects malformed/oversized epochs, and never strips a valid authority component. -- The web preload compatibility overload preserves requested-host echo for runtime reads; this does not enable direct-SSH coordination in paired web clients. -- A stale `ssh:getState` reply arriving after a disconnect/reconnect push cannot change status or fill authority; a same-watermark reply can fill only missing authority. -- Main host-catalog admission rejects a row whose explicit execution host contradicts its legacy connection host; it returns no authoritative rows instead of selecting or hiding that row by precedence. - -### Renderer worktree/catalog/lineage fences - -- The coordinator in-flight key differs by host, full authority, catalog revision, and authoritative requirement; the shared coalescer key remains unchanged. -- Inputs that differ only by `authorityRequirement` do not join, and the resulting token echoes that exact requirement. -- Exact overlapping requests join; the same key after completion runs again. -- An old result after disconnect/reconnect or relay-only replacement causes zero store publications. -- Git identity, hosted-review links, purge state, both worktree maps, and best-effort lineage remain byte-identical on stale results. -- Local, another SSH target, and runtime owners with the same repo ID remain unchanged. -- Target snapshot hydration and persisted-terminal reconnect use host-qualified worktree references, prune the retry/live/history ledgers of tabs authoritatively deleted from that exact scope, and leave retained or sibling SSH, local, WSL, folder, and runtime tabs, PTY indexes, layouts, active state, generations, and recovery ledgers unchanged. -- A renderer worktree result is admitted only while every current same-ID repo row still has valid, non-contradictory explicit/legacy ownership; malformed or contradictory provenance introduced during the provider await makes the result stale without store mutation. -- A target-scoped catalog fetch cannot be superseded by focused-runtime `fetchRepos`. -- Host-scoped lineage deletes a stale direct SSH row while preserving local, another SSH target, runtime, and unknown-owner rows. -- Runtime-focused UI state cannot redirect direct SSH catalog, worktree, or lineage ownership. -- An ID-only first-wins hydration index containing the same worktree ID under SSH A and SSH B is never authoritative for direct reconnect; a target-B snapshot reattaches only the host-qualified B row or fails closed. -- Pre-catalog direct SSH scope with a focused runtime treats focus fallback as ambiguous and still recovers tabs supported by explicit PTY/host provenance. -- An explicit `ssh:B` worktree with repo-derived `ssh:A` is `contradictory-owner` for both targets and remains byte-identical. The inverse mismatch, an SSH host plus explicit runtime owner, and conflicting folder group/repo connections fail the same way. -- Repo-derived ownership is accepted only when explicit worktree ownership is absent; adding a conflicting explicit owner converts the same row from accepted to preserved/contradictory without cross-host deletion. -- Git 2.25-compatible worktree fallbacks remain unchanged. - -### Direct SSH scheduler/coordinator - -- A singleton reconnect begins terminal finalization immediately without a collection delay. -- Target B terminal finalization completes while all five direct provider slots are occupied by target A. -- Target B's first repo starts after at most one bounded provider deadline when it arrives behind five A calls. -- Round-robin admission prevents a large target from continually reoccupying every released slot. -- Peak coordinator-owned detected-worktree calls is five; runtime/sidebar activity can raise total app concurrency without failing this assertion. -- Joined consumers receive distinct waiter lease IDs and one shared provider request ID. Canceling one settles only that lease while the other completes from the original call; no provider cancel is sent. -- Last-waiter release sends exactly one cancellation for that shared provider request ID. Authority invalidation sends exactly one cancellation for each affected in-flight provider request, including multi-repo preparation; no cancellation is sent merely because one lease leaves while another current-authority lease still owns that invocation. A waiter lease ID presented to main is rejected and cannot abort provider work. -- A coordinator lease joining sidebar/filesystem work cannot abort that work when the coordinator is superseded; the remaining non-coordinator lease keeps the provider request alive. -- A timeout sends `rpc.cancel`, settles locally, and releases its local slot without a relay acknowledgement. -- Repeated timeout replacements never exceed the two-call cancel-debt allowance; denied work settles as terminal `cancel-budget-exhausted` and is reported separately. -- After a first retryable timeout, the repo task is `retrying`: lineage calls, preparation tokens, sync, and snapshot apply remain at zero until the retry settles. -- A successful retry then releases one lineage read and one token; a second timeout or cancel-budget exhaustion releases a degraded result without starving another target. -- An exact-equal `replaceAuthority` call preserves every pending lease, live binding, and overlapping preparation and sends no cancellation. -- A same-authority reconnect rechecks terminals but does not rebump a healthy current-authority binding. -- A newly hydrated tab receives one retry later under the same authority. -- A tab whose exact ownership becomes visible during that target's preparation receives one retry without delaying the first terminal finalization. -- An authority advance with five old slow calls cancels queued work, settles/aborts old leases, starts new terminal finalization immediately, admits new work under cancel-debt rules, and permits zero old main/renderer mutations. -- A changed authority supersedes old target work by arrival, without numeric comparison. -- A same-authority connected rebroadcast performs bounded correction plus preparation/sync without retrying healthy terminals. -- A failed or timed-out pane on attempt one rotates the tab once; attempt-two failure cannot start attempt three or revoke continuation authority from siblings already settling. -- Three authority rotations inside the stabilization window perform three immediate terminal checks but only one full preparation for the final stable authority. -- `prepareOnly` never invokes terminal retry or reconnect sync. -- A preparation-only request shares exact in-flight repo work with reconnect preparation but not reconnect finalization. -- A completed preparation never suppresses a later same-authority wake or snapshot preparation. -- Stop locally settles queued/in-flight waiters without waiting for relay acknowledgement and prevents post-stop finalization. -- One system resume/browser-online event advances #8255 remote-runtime backoffs and direct-SSH wake preparation independently; runtime-owned SSH rows never enter the direct coordinator, and a direct tab already live under current authority is not double-bumped. - -### Atomic terminal recovery - -- Many live tabs/worktrees clear in one store publication; a second clear is a true no-op. -- Only tabs with `tab.ptyId != null` are changed. -- A null-PTY tab with `pendingActivationSpawn` remains byte-identical. -- A live-PTY tab consumes `pendingActivationSpawn` in the same patch that clears its tab and split-pane PTY indexes. -- `lastKnownRelayPtyIdByTabId` survives and the `#9911` orphan predicate remains reconnectable. -- Live split-pane PTY indexes and Codex restart metadata clear. -- Layouts, deferred sessions, pending reconnect IDs, shutdown/suppression state, titles, and agent state remain unchanged. -- No worktree activity, sorting, or metadata persistence occurs. -- Exact target A clear/retry leaves target B, local, WSL, floating, and runtime-owned tabs unchanged even with duplicate repo IDs. -- Exact direct SSH folder workspaces clear/retry; mixed, ambiguous, and runtime folders do not. -- A parsed target PTY recovers a stale-catalog tab only without contradictory ownership. -- A relay/provider replacement after a missed disconnect clears a pre-authority `ptyId` and retries it while preserving last-known relay IDs. -- Binding provenance for another authority or no provenance is stale; a successful current-authority spawn becomes live and suppresses healthy correction. -- One authority chain permits at most two automatic correction attempts even when each timeout exceeds 30 seconds; later same-authority triggers remain exhausted until authority replacement. -- Rejected stale/mismatched acknowledgements preserve every store map and publish nothing. Concurrent split spawn or reattach acknowledgements share one exact attempt; the first establishes the fallback/live lease, and both already-mounted and post-success-mounted siblings join it. -- Primary exit before a sibling binds preserves the exact continuation lease and activation suppression; the sibling then becomes the fallback without a corrective remount. -- Primary and non-primary split detach both preserve exact authority and retry history on the surviving source and detached destination; an all-null pending-only detach preserves the lease before either side binds, and a same-authority correction leaves both live. -- Disconnect retains exact existing ordering and effects for `clearRemoteDetectedAgents`, `clearPortForwards`, `setDetectedPorts([])`, and atomic PTY clear. -- Disconnect and reconnect emit zero paired `session.tabs.close`/`closeLifecycle`, provider shutdowns, or process signals. -- A manually parked direct-SSH worktree follows the same store patch and retry eligibility without invoking parking, close, or layout mutation. - -### Remote-workspace and hydration integration - -- Connect plus sync performs one logical preparation and passes its token through a nonempty snapshot apply without preparing again. -- An unsolicited snapshot joins exact in-flight preparation but starts a new preparation after that work settles. -- A later same-authority snapshot referencing a newly created worktree resolves and imports its tabs. -- Preparation-only snapshot handling never bumps terminal generations. -- Preparation-only means no coordinator generation bump; existing snapshot-driven terminal reattach remains and is finalized afterward. -- Initial hydration with no previous renderer state follows the explicit `initial-hydration` origin into `prepareOnly` and performs zero reconnect retries; reconciliation retains that origin. -- Reconnect finalized before session hydration retries newly hydrated tabs exactly once afterward. -- Immediate finalization bumps a tab, then a snapshot with the same stable tab ID and an older/absent generation cannot reduce the local generation or suppress correction. -- Snapshot hydration that lands after a newer local retry preserves the newer terminal-recovery revision, pending attempt, and current binding provenance. -- Snapshot-imported `ptyId` without current-authority live evidence remains retry-eligible; successful exact target-scoped `reconnectPersistedTerminals` retires the pending attempt and records it live, while failure re-arms it. -- Snapshot projection and reconnect are host-qualified end to end; another SSH target, local, WSL, and runtime-owned state remain byte-identical despite colliding raw IDs or paths. -- Same-authority wake rebroadcast performs bounded fresh discovery. -- Revision-zero sync captures `hasLocalTabs` before `remoteWorkspace.get`, uploads only on that capture, and revalidates authority before publish. -- Snapshot apply rejects a token whose `snapshotRevision` differs, and reconnect sync can create a `SnapshotApplyToken` only from the snapshot fetched by that same fenced operation. -- Repo-qualified snapshot mapping keeps same-named repo paths isolated; a legacy path-only entry applies only with one exact-target candidate and otherwise fails closed. -- Folder workspace keys never enter snapshot projection. -- Hydration timeout does not undo terminal recovery. - -### Performance and diagnostics - -Seed direct SSH targets, a runtime environment, sidebar refreshes, worktrees, folder workspaces, split tabs, and large terminal maps. Assert: - -- coordinator-owned direct SSH detected-worktree concurrency never exceeds five; -- runtime and sidebar work are excluded from, and may exceed, that scoped count; -- terminal retry is submitted before any provider task and uses one publication; -- disconnect uses one publication and schedules session persistence once; -- queue wait, provider duration, timeout, and cancellation are distinct; -- canceled/stale outcomes do not console-error or increment degraded counts; -- diagnostics contain counts/durations plus only an ephemeral target alias; -- the typed telemetry schema rejects identifiers and emits observed queue/provider distributions, timeout/retry/cancel-debt counts, flapping damping, and successful correction results; and -- the adapter computes bounded p50/p95/p99 values from each operation's real scheduler samples. - -## Implementation map - -- `src/main/ssh/ssh-provider-authority.ts` composes epoch issuance with `ssh-connection-generation.ts`; `src/main/ipc/ssh.ts` rotates on every provider transition, registers before `connected`, and publishes the pair. -- `src/shared/ssh-types.ts`, `ssh-retained-payload-admission.ts`, `runtime-client-events.ts`, and public SSH state projection define, validate, and retain the complete authority. `src/preload/api-types.ts`, `src/preload/index.ts`, startup reconnect, runtime SSH state, and web mutation readers copy it unchanged. -- `src/renderer/src/store/slices/ssh-target-cleanup.ts` and `ssh.ts` make the authority pair equality-significant and patch-preserving. The state-event/reconciliation code in `useIpcEvents` owns arrival watermarks. -- `src/main/ipc/worktrees.ts` and the provider authority module own exact host/provider resolution, the provider-request registry, main deadlines/aborts, post-await fences, qualified lineage pruning, and host metadata backfill. Main has no waiter-lease concept. -- `src/renderer/src/store/slices/detected-worktree-refresh-leases.ts` owns the existing public coalescer key, compatible provider invocation entries, independently generated provider request and waiter lease IDs, ref-counted last-waiter cancellation, and per-lease settlement for every caller. -- `src/renderer/src/hooks/direct-ssh-worktree-refresh-scheduler.ts` acquires shared leases and owns the five local slots, target round-robin, authority/revision wrapper key, nonterminal `retrying` state, one timeout retry, and cancel-debt allowance. -- `src/renderer/src/hooks/direct-ssh-reconnect-coordinator.ts` owns per-target authority replacement, preparation waiters, stabilization damping, preparation barriers/tokens, pending terminal attempts, success ledger, and bounded corrective triggers. -- `src/renderer/src/lib/direct-ssh-target-scope.ts` uses explicit provenance for Git and folder scope; it never reads focused-runtime ownership. -- Terminal slice actions and `src/renderer/src/store/slices/direct-ssh-terminal-recovery.ts` own atomic clear, stale-binding invalidation, transient PTY authority, attempt settlement, and single-publication retry projection. -- `src/renderer/src/hooks/remote-workspace-target-sync.ts` owns capture-before-await revision-zero push, token/revision fences, repo-qualified legacy-safe resolution, local recovery preservation, snapshot-driven reattach, and post-hydration finalization. -- Typed aggregate telemetry owns the privacy schema, per-operation distributions, and fail-soft histogram emission. External dogfood dashboard/query configuration remains an operational follow-up. - -## Rollout - -The implementation preserves this dependency order: - -1. Add the opaque epoch and `rotateSshProviderAuthority`, expand `connectionGeneration` rotation to the same transition set, and inventory every state equality/copy/preload/retained/reconciliation boundary. Land complete-pair publication, malformed partial-authority rejection, retained-admission, stale-reconciliation, provider-before-broadcast, and old-mutation-expectation tests before any coordinator routing. -2. Add host-qualified detected-worktree and lineage IPC, discriminated authoritative response admission, exact main provider selection, main-owned 30-second deadline, provider-request cancellation, and main pre-mutation fences. Preserve the web/runtime overload without enabling direct-SSH web coordination. Keep the coordinator disabled. -3. Refactor renderer worktree/catalog/lineage reads to immutable results with pre-mutation full-authority fences. Add the host-scoped catalog lane independent of focused-runtime supersession, all-provenance contradiction rejection, legacy lineage host backfill, and shared coalescer leases with distinct waiter/provider IDs. -4. Add exact target scope, atomic disconnect clear, stale-authority binding invalidation, retry-attempt settlement, and transient binding provenance. Switch disconnect and reconnect terminal handling together so Git/folder clear-retry symmetry and detected-agent/port cleanup remain intact in every commit. -5. Add the dedicated fair direct SSH scheduler and per-target coordinator with local-settlement semantics, the first-timeout preparation barrier, one timeout retry, cancel-debt admission, authority-advance invalidation, same-authority correction, and flapping damping. Route connected events through reconnect finalization; leave #8255 remote-runtime recovery and runtime-owned SSH rows unchanged. -6. Extract `prepareRemoteWorkspaceTarget`, `syncRemoteWorkspaceAfterConnect`, and `applyRemoteWorkspaceSnapshot` into `src/renderer/src/hooks/remote-workspace-target-sync.ts`. Split preparation-only from reconnect mode, pass the full operation token through revision-zero push and snapshot apply, preserve newer local recovery state, finalize imported terminal hints, and remove repeated preparation calls. -7. Enable typed aggregate diagnostics/telemetry and dogfood with renderer-catalog owner aliasing, many direct targets, an active focused runtime, sidebar activity, folder workspaces, relay-only flapping, timeout/retry/cancel debt, missed disconnects, failed pane spawns, arrival-order races, system resume/browser online events, and cross-device snapshot changes. - -Stage 5 is gated on stages 2–4. The coordinator must never call catalog or lineage APIs whose ownership depends on `settings.activeRuntimeEnvironmentId`; a partial coordinator-first rollout is forbidden. System-resume/browser-online recovery must not double-bump a tab already live under the direct SSH authority ledger. - -Release checks: - -- zero host/authority mismatch accepted at either main or renderer mutation fences; -- zero authority component dropped at equality, retained, preload, startup, public-state, or reconciliation boundaries; -- zero authoritative direct-SSH result constructible or admitted without the full authority pair; -- no cross-host provider selection in duplicate-ID integration tests; -- no contradictory provenance accepted by OR-matching or repo fallback; -- terminal finalization is scheduled before provider discovery and is not delayed by another target or runtime/sidebar work; -- p95/p99 direct scheduler queue wait and provider duration, plus timeout/retry/cancel-debt rates, are reported separately from same-relay non-coordinator traffic; -- peak coordinator-owned direct SSH detected-worktree concurrency is at most five; -- waiter cancellation is lease-local, last-waiter release sends one cancellation for its provider request, authority invalidation sends exactly one per affected in-flight provider request, provider cancellation settles without relay acknowledgement, and cancel debt remains bounded; -- no lineage read, preparation token, or sync starts while a first timed-out repo remains retrying; -- authority advance invalidates old queued/in-flight work and relay flapping produces only one stable preparation wave; -- missed disconnect, failed spawn, and hydration overwrite cases converge through bounded same-authority correction; -- later same-authority snapshots containing new worktrees converge; -- revision-zero push preserves capture-before-await ordering and stale reconciliation cannot resurrect connected state; -- direct SSH lineage deletion is host-correct; and -- Git and folder terminal overlays clear and retry symmetrically while port and detected-agent cleanup remains intact. - -Rollback disables coordinator routing with build-time `VITE_DIRECT_SSH_RECONNECT_COORDINATOR=false` or session key `orca.directSshReconnectCoordinator.enabled=false` while retaining composed authority rotation, authority-boundary preservation, host-qualified IPC, mutation fences, and atomic terminal actions. The fallback reconnect path uses the dedicated bounded scheduler and preserves port/detected-agent cleanup; it does not restore host-blind or unbounded `Promise.all`. - -## Cross-platform and compatibility - -- Use existing execution-host, folder-workspace, workspace-key, SSH PTY-ID, and path utilities. Do not concatenate execution-host IDs or parse filesystem paths. -- The design introduces no keyboard behavior or platform-specific UI. -- Direct SSH on Windows, macOS, Linux, and WSL follows the same host/authority rules. -- Cancellation uses typed provider request IDs over Electron IPC and existing `AbortSignal` support; waiter lease IDs remain renderer-local, and no OS signal semantics or new cancel-ack protocol crosses the wire. -- No Git command, option, parser, or native dependency changes. Git 2.25 compatibility and capability fallbacks remain authoritative. -- Remote runtimes require no server upgrade. Runtime-host requests continue through the existing runtime RPC route. -- Keep new modules within normal line limits; do not add or widen a `max-lines` disable. - -## Rejected alternatives and overreach - -### Treat in-flight coalescing as collapsing the current sequential scan count - -Rejected. The connected refresh, sync preparation, and snapshot preparation await one another. Their provider reads do not overlap, so the current single-flight map has no live promise for the later wave to join. It can reduce unrelated overlapping calls, but does not invalidate the `2R`/`3R` sequential-path diagnosis. - -### Use either main connection generation or provider epoch as an independent clock - -Rejected. The renderer fallback counter has different ownership and is never authoritative. The existing main generation and new opaque epoch are composed by one rotation helper and transition set: mutation consumers compare the generation, provider/recovery consumers compare the pair, and no producer may advance them independently. - -### Cache completed preparation for an entire authority - -Rejected. Stable connections can receive wake refreshes and later snapshots referencing newly created worktrees. Only exact overlapping input work is shared; completed work never suppresses later inputs. - -### Use one global wave and FIFO for direct SSH plus runtime discovery - -Rejected. It couples terminal recovery and target preparation to unrelated queues and timeouts. Direct terminal finalization is synchronous per target; direct provider work uses a dedicated fair bounded scheduler. - -### Let preparation-only reuse reconnect finalization - -Rejected. Snapshot preparation must never initiate coordinator retry or reconnect sync. Existing snapshot-driven persisted-terminal reattach remains part of apply and is reconciled with current-authority binding evidence afterward. Only immutable catalog/repo/lineage reads may be shared. - -### Fence only before the final worktree-map merge - -Rejected. Main lineage/metadata changes and renderer git-identity routing occur earlier. Every authoritative side effect is downstream of an exact host/authority fence. - -### Use `{ forceLocalOwner: true }` for direct SSH lineage - -Rejected. It cannot authoritatively replace an SSH host scope and leaves deleted SSH lineage behind. The wire response and renderer replacement scope must both name the exact execution host. - -### Reuse the component sidebar single-flight coalescer - -Rejected. It is component-scoped, fire-and-forget, and lacks provider-authority, cancellation, terminal, and preparation semantics. The coordinator instead acquires leases from the shared detected-worktree provider coalescer while preserving its public key shape. - -### Replace direct `Promise.all` with `refreshRuntimeProjectWorktrees` - -Rejected. It bounds only one invocation, remains host-blind at the desktop IPC boundary, and does not remove repeated preparation. - -### Use one scheduler per SSH target - -Rejected. It permits `5 × targetCount` locally unsettled provider calls. One dedicated fair scheduler provides a truthful five-local-call bound without a cross-target completion barrier; cancel debt states the separate late-relay allowance. - -### Wait for a relay cancellation acknowledgement - -Rejected. `rpc.cancel` is a notification and canceled handlers intentionally send no response. Local waiter/provider settlement releases scheduler ownership; late effects remain authority-fenced and replacement admission is bounded by cancel debt. - -### Expand direct SSH coordination to the paired web client - -Rejected. Paired web clients cannot subscribe to the desktop direct-SSH state path. Preserve shared overload compatibility and host echoes, but do not create a new direct-SSH web transport to address an unreachable version of the shim claim. - -### Apply a fixed collection debounce - -Rejected. It taxes the singleton common case and is unnecessary when exact overlapping work already coalesces. Fair incremental admission handles multi-target bursts. - -### Call `fetchAllWorktrees` - -Rejected. It refreshes unrelated hosts, weakens failure isolation, and collides with the separate sidebar surface. - -### Reuse permanent target-removal cleanup - -Rejected. Removal intentionally deletes last-known and deferred liveness. Reconnectable disconnect must preserve them. - -### Batch repeated `clearTabPtyId` calls - -Rejected. React batching does not remove Zustand updater work, global map cloning, activity writes, or session debounce resets. - -### Move reconnect recovery into main - -Rejected. Main owns provider authority and mutation fences; renderer owns tab bindings, session projection, and Zustand updates. The host/authority boundary is the smaller ownership correction. diff --git a/docs/reference/plans/2026-07-28-orchestration-seamless-update-migration.md b/docs/reference/plans/2026-07-28-orchestration-seamless-update-migration.md deleted file mode 100644 index 18ceea5bff2..00000000000 --- a/docs/reference/plans/2026-07-28-orchestration-seamless-update-migration.md +++ /dev/null @@ -1,576 +0,0 @@ -# Preserve active orchestration work across contract updates - -Status: implementation validation - -Date: 2026-07-28 - -## Decision - -Do not block updates, restart active workers, or revive the retired scheduler. - -On first launch after the contract update, atomically adopt the durable -pre-Run graph into one ordinary lightweight Run.

A -current event is preferred but is not required before the worker's first -post-restart lifecycle command when controller inventory proves the exact -original PTY and process incarnation are live. - -For each candidate it resolves the union of: - -- durable Dispatch assignee and pane; -- equivalent-pane aliases; -- remote attachment and host ownership; -- coordinator candidates from active legacy coordinator rows, Task creator - handles, Dispatch coordinator/parent provenance, and direct-message - sender/recipient history; -- the restored terminal inventory and process incarnation; and -- the hydrated, previously authenticated hook pane/launch-token association. - -The candidate commits only when that union identifies exactly one role and -row. The orchestration database stores a SHA-256 token commitment, never the -raw token. The existing owner-only hook status cache is an input to the -one-time commitment, but a hydrated status is not enough to mutate. - -Every compatibility call then requires: - -- a hidden launch token and pane inherited by the calling process; -- the immutable pre-update hook commitment, plus either a matching - current-runtime hook event or exact current controller proof of the original - PTY and process incarnation; -- a live PTY with the committed handle, host scope, and process incarnation; -- the committed principal and exact active legacy Dispatch or adopted Run; and -- an operation-specific unique match. - -The current hook event or exact controller inventory proves that the process -survived the restart; equality with the pre-update commitment proves it is the -same launch. If the hook cache was absent, the provider cannot report the -proof, the token changed, or any candidate is ambiguous, the row remains -read-only. - -For new Dispatches, persist the launch-token hash at dispatch time so later -contract updates do not depend on hook-cache recovery. Never return or log raw -tokens. Add explicit RPC-envelope, structured-log, error, and CLI JSON -redaction tests. - -Host scope is runtime-owned: - -- local: stable local execution-host identity; -- WSL: stable native execution-host identity plus distro; -- SSH: saved-host authority plus remote pane/process identity; and -- federated runtime: authenticated peer fingerprint plus remote attachment. - -`pickRemoteCliEnv`, SSH relay forwarding, WSLENV, and the legacy in-process SSH -fallback must carry the hidden evidence without exposing it in command text or -logs. A local runtime never accepts a raw remote token as local authority. -Pre-update WSL processes without the token cannot use the lifecycle adapter. - -For SSH, the host passthrough and in-process fallback stamp the saved target, -`SshRelaySession` connection incarnation, and attachment provenance from the -authenticated runtime channel; caller environment cannot choose them. WSL -stamps the runtime-owned native host and distro in both the full bridge and -fallback bridge. The verifier intersects those stamps with the committed host -scope before considering token or pane evidence. - -## Mixed-contract Run and mail routing - -The adopted Run is a normal current Run. Tasks belong to it, so a current retry -of a preserved Task naturally routes to the same Run without a cross-Run Task -reference. - -Message delivery is selected by `messages.delivery_contract`, not by Run ID: - -- old and adapter-created direct messages are `legacy_direct`; -- current sends are `current_delivery`; and -- migration rejections and non-actionable history are `audit_only`. - -Current Run Delivery creation, filtering, waiting, and acknowledgment select -only `current_delivery`. Legacy `check` selects only the exact principal's -`legacy_direct` address. History and inbox may show all three with explicit -labels but never attach actions to `audit_only`. Mixed legacy/current attempts -under one Task are covered across send, ask, check, reply, and settlement. - -The original coordinator is automatically associated with the adopted Run -after its principal proves live. `run-use` may bind that same principal without -converting legacy Dispatches. A different coordinator cannot silently take -over while a legacy attempt is active; an explicit recovery takeover is a -separate current-contract action and revokes legacy coordinator mutation -authority before rebinding. - -When that coordinator uses old direct `check`, the adapter also performs a -non-consuming existence check for `current_delivery` mail. It never mixes the -messages into legacy output; it prints the exact current Run check command and, -after that command creates a Delivery, the exact acknowledgment form. This -keeps an unchanged coordinator informed about current retries without -weakening current Delivery semantics. - -## Exact legacy adapter - -The CLI keeps accepting the old flags. It sends a hidden compatibility -envelope; the runtime, not the CLI, decides whether legacy behavior applies. - -Version B generates a random hidden `compatibilityInvocationId` once per CLI -process and reuses it for every transport reconnect by that invocation. -`legacy_operation_receipts.operation_key` is this invocation ID for B calls. -The method and canonical payload hash must also match. - -Attested compatibility calls bypass the rotating-auth generic mutation ledger -after the contract fence routes them to the adapter. Their only dedupe boundary -is the compatibility-principal receipt transaction described here; current -calls continue through the existing generic ledger unchanged. - -Version A had no invocation ID. Cross-cutover reconstruction is therefore -limited to effects with a durable semantic identity: final settlement per -Dispatch, still-pending ask per normalized question/options/recipient, reply -per source/principal/body, and read recovery per message. Heartbeat and -escalation remain at-least-once across an A-to-B manual retry because -collapsing identical commands could suppress a legitimate later event. Tests -and guidance do not promise cross-cutover exactly-once behavior for those -repeatable signals. - -An A-era ask that was already answered before its output was lost is also -ambiguous. B does not guess whether the same text means retry or a new -question. Its answer is in the durable recovery cohort and the error tells the -agent to run the exact legacy check command first. After that answer is printed -and acknowledged, a new B invocation with identical text creates a new -question. If multiple identical A threads exist, ask fails ambiguous and -recovery check drains them by message sequence; no arbitrary thread is chosen. - -### Lifecycle `send` - -- `heartbeat` and `worker_done`: resolve Task + Dispatch from the payload, then - intersect them with the verified worker principal. -- `escalation`: resolve Task + verified worker principal to exactly one active - legacy Dispatch because the old prompt supplied no Dispatch ID. -- Preserve the old direct coordinator recipient after verifying it belongs to - the adopted Run principal. -- Infer missing `worker_done` outcome as `failed` only when the trimmed subject - is `Failed` or begins `Failed:`; otherwise infer `succeeded`. -- Normalize to the current internal settlement model. - -Compatibility validation happens before message insertion. Current lifecycle -handling is not refactored through this prevalidation: its existing -invalid-capability audit message behavior remains locked by regression tests. - -The DB commits the direct message, lifecycle effect, and compatibility receipt -in one transaction. If a pre-update `worker_done` already settled the Dispatch, -the adapter reconstructs the matching semantic receipt from the existing -message and settlement. The persisted A settlement is authoritative: the -pinned A reconciler recorded even a `Failed:` subject as completed, so B -returns that original completed result rather than retroactively changing Task -or dependency state. Only a not-yet-accepted B call applies the corrected -failure inference. A conflicting retry fails. - -### `check` - -Legacy check is at-least-once: - -1. a read RPC returns the exact unacknowledged `legacy_direct` message IDs - without changing them; -2. the CLI prints the complete response; and -3. a hidden ack atomically records receipts and marks those exact rows read. - -A cut after read and before ack replays the same IDs. `--peek` and `--all` -remain read-only. - -Version A could mark a message read before losing its response. On adoption, -every eligible read direct message connected to a still-active legacy attempt -and lacking a post-adoption receipt is inserted into a durable recovery cohort -using `legacy_mail_receipts` with `acknowledged_at = NULL`. Legacy check drains -that stable cohort in bounded sequence-ordered pages before ordinary unread -mail. Each page is labeled -`[LEGACY RECOVERY REPLAY — MAY HAVE BEEN SEEN]`, replays until its post-print -ack, and then advances. The cohort never grows after adoption, so every -eligible row is covered without an unbounded response. Settled-at-cutover and -unrelated historical mail do not enter it. - -### `ask` - -Legacy ask is an idempotent mutation followed by a resumable read: - -1. create or find the direct legacy gate/question by verified Dispatch, - normalized question, options, and recipient; -2. atomically commit its message/thread plus operation receipt and return the - stable question ID; -3. wait in bounded read-only slices using that ID; and -4. after printing the answer, hidden-ack that exact answer. - -On first adoption, existing pending decision-gate threads are indexed into the -same semantic identity. A retry resumes them instead of creating another gate. - -### `reply` - -Legacy reply requires the source thread, the verified coordinator principal, -and a unique question owned by the adopted Run. One transaction inserts the -reply, resolves the exact gate, marks the exact source, and completes the -receipt. - -An existing pre-update reply with the same source, principal, and body is -reconstructed as success. A second body for the same source/principal is a -conflict, not another reply. - -### Coordinator and Task commands - -After automatic binding, unchanged Task listing, Task settlement, dispatch, -and gate inspection use the adopted Run. A new attempt receives a current -preamble, capability, launch-token commitment, and current message contract. -No unrelated Task can be created until the migrated coordinator binding is -proven or explicitly taken over. - -## Windows update behavior - -No compatibility mutation holds a DB transaction while waiting. Windows -legacy `ask` commits the question, prints its stable ID and exact resume -command, then exits before a long wait whenever the installed launcher cannot -prove that the executable is replaceable. - -The native packaged launcher sets an internal -`ORCA_WINDOWS_PACKAGED_CLI_LAUNCHER=1` marker for its Electron-as-Node child. -After the DB commit, legacy `ask` writes and flushes the stable question ID and -the exact resume command, then exits with a documented `75` resume-required -status. The command name comes only from the validated inherited -`ORCA_CLI_COMMAND` packaged enum: `orca` for native packaged terminals or -`orca-ide` for packaged WSL. Arbitrary environment text is rejected rather -than rendered. The launcher propagates status 75. No long wait starts on this -path. - -This compatibility path makes the accepted question recoverable without -claiming Windows updater or uninstaller process ownership. Generic executable -drain, replacement, and uninstall behavior remains separate updater -reliability work and requires its own Windows artifact proof. - -## Rendering and authoritative guidance - -Formatting is authority-aware: - -- `[LEGACY COMPATIBILITY]`: live and attested; show only supported commands; -- `[LEGACY RECOVERY REPLAY — MAY HAVE BEEN SEEN]`: one bounded cutover replay; -- `[LEGACY READ-ONLY]`: retained but unactionable; no Reply or Ack hint; and -- current messages: unchanged. - -Update `skill-guides/orchestration.md` and regenerate its bundled source. The -guide explains automatic adoption, exact continuity, the retired scheduler -boundary, proof failures, current retries, and the Windows ask resume fallback. -It must not tell agents to restart a worker whose Dispatch was adopted. - -Formatting cannot use database provenance alone; current liveness and -attestation are runtime facts. Recovery may reveal the exact already-live PTY -once as an inactive background tab. It never creates a PTY or process, writes -input, switches workspaces, focuses, splits, or injects a terminal. - -## Deterministic verification - -### Schema and authority - -- Migrate exact pre-v7, hard-cutover, current, partial, WAL, reset, and fresh - fixtures; preserve IDs and row counts and reuse one adopted Run. -- Assert Task, Dispatch, decision-gate, message, question-thread, and retained - Delivery Run ownership agrees; outstanding legacy Deliveries are fenced. -- Prove current retries in the adopted Run remain current across repeated - migrations. -- Test unique worker/coordinator import from prior hook commitment plus current - live hook, and every forged, stale, wrong-host, wrong-pane, wrong-process, - duplicate-token, duplicate-role, equivalent-pane, and remote-attachment - ambiguity. -- Race a current-runtime hook before adoption and prove the immutable startup - commitment is neither overwritten nor confused with live proof. -- Cover manual coordinators with no `coordinator_runs` row and reject - conflicting candidates from Task, Dispatch, and message provenance. -- Assert all legacy authority failures occur before message/receipt/gate/state - effects while current invalid-capability rejection remains unchanged. -- Assert tokens are absent from RPC logs, errors, CLI output, and orchestration - storage. - -### Exact old behavior and replay - -- Replay the pinned prompt's heartbeat, successful and `Failed:` - `worker_done`, task-only escalation, ask, and consuming check. -- Replay the old formatter's reply command separately. -- Cover every operation once after B and once accepted by A immediately before - the cutover where a durable semantic identity exists, including the bounded - recovery replay for an A check and preservation of A's persisted settlement. -- Prove one B invocation reuses its invocation ID across reconnect, while - separate identical heartbeat/escalation invocations remain distinct. -- Inject real transport cuts after check read, ask commit, reply commit, and - completion commit; prove stable IDs and one receipt/effect. -- Page a recovery cohort larger than one response limit across repeated - disconnects and prove every eligible row appears until ack, then never again. -- Test mixed legacy/current attempts for every send/check/ask/reply route and - prove current Delivery cannot consume legacy direct mail and old coordinator - check only advertises the exact non-consuming current Delivery command. - -### Live two-launch E2E - -The focused renderer/daemon restart regression reconstructs the rc.3-era -orphan artifact in a shared candidate profile: a durable legacy Dispatch, -sleeping provider record, and live daemon PTY with its visual binding removed. -It proves startup restores the exact PID, PTY/incarnation, handle, tab/leaf, -Task, and Dispatch; emits no provider-resume spawn or interruption; preserves -coordinator focus; and remains inert after switching away and back. This -candidate/candidate fixture covers the renderer regression deterministically -but does not replace the distinct installed-A/candidate-B packaged cutover -journey below. It does not claim packaged Windows updater behavior. - -Use distinct installed A and B artifacts plus an external append-only fake -agent spawn ledger: - -1. launch A with coordinator and worker terminals and record the replaceable A - desktop/main PID, runtime ID, version, and artifact hash separately from the - durable daemon, coordinator, and worker identities; -2. accept one command with durable semantic identity on A—pending ask, reply, - completion, or check—cut its response, close A without stopping the daemon - or fake agent, install B, and prove B owns the relaunched runtime; -3. assert A's desktop/main process and runtime are gone, B has a different - desktop/main PID, runtime ID, version, and artifact hash, while the daemon - plus coordinator/worker PID and start time, PTY/session, terminal handle, - tab/leaf/pane, worktree, Task, and Dispatch remain byte-identical; -4. prove that exact pending ask, reply, completion, or check resumes or - deduplicates on B; do not use heartbeat, escalation, or an already-answered - A ask as an exactly-once oracle; -5. run the remaining exact old lifecycle commands and settle the same - Dispatch; -6. switch away and back and assert no second spawn/tab and no - `Conversation interrupted`; and -7. create a current attempt on preserved state and prove current grammar. - -The append-only spawn ledger and an append-only interruption ledger, daemon -inventory, runtime terminal inventory, and every viewer DOM independently -prove one launch, process, handle, tab, and no `Conversation interrupted`. -Transport fault injection cuts the real CLI connection after check output but -before ack, and after ask, reply, and completion commit. Re-run the byte-exact A -argv under B and assert stable IDs plus exactly one message, gate, reply, -settlement, and receipt. - -Retain #11142's local visible-inactive test and extend its oracle beyond DOM -counting with the ledgers and host inventory. - -Run separate remote journeys: - -- headed paired server A-to-B with a surviving external client; -- headless `orca serve` A-to-B with the same surviving-client oracle; -- both prove the remote PID/PTy continuity, both viewer states, zero - client-local handles/tabs, and wrong-host evidence with zero effects; -- Docker SSH restart/reconnect with a remote proof file binding the process, - pane, and token commitment; -- physical Windows WSL coverage proving the correct distro and rejecting a - wrong-distro token; and -- a git-independent folder workspace parameter through the same adoption - journey. - -Packaged Windows updater continuity is outside this migration gate. A separate -updater change must prove candidate-built A/B install, executable release, -resume, and normal uninstall behavior on Windows before making that guarantee. - -## Implementation slices - -1. Schema, atomic Run adoption, per-row contract provenance, and mixed mailbox. -2. Hook-commitment import, live principal verifier, host scopes, and redaction. -3. Atomic compatibility receipts plus lifecycle send/escalation. -4. Check read/ack and cutover recovery replay. -5. Ask create/resume, reply conflict semantics, and coordinator binding. -6. CLI hidden envelope, SSH/WSL forwarding, Windows resume fallback. -7. Authority-aware formatting and the version-matched orchestration guide. -8. Two-launch, remote, platform, and #11142 regression coverage. -9. Focused unit/type/lint/E2E checks and final adversarial review. - -## Definition of done - -- Updates are never blocked. -- Every durable legacy Task is owned by an ordinary visible Run. -- Every provably original live legacy Dispatch can finish through its existing - prompt without changing process or worktree. -- New attempts use the current contract and mailbox in that same Run. -- No authority comes from IDs or handles alone. -- No adoption step starts, stops, writes, signals, focuses, splits, or injects - a terminal.

The controller also keeps a registry -above providers so separate local/SSH routes cannot independently claim the -same identity. - -## Structured requests - -### Explicit resume - -`terminal.ensureAgentSession` accepts only a supported agent and normalized -provider identity: - -```ts -{ - kind: 'explicit' - worktree: string - agent: ResumableTuiAgent - providerSession: { - key: 'session_id' | 'conversation_id' - id: string - transcriptPath?: string - } - agentArgs?: string | null - launchPreferences?: { model?: string; effort?: string; mode?: string } - presentation?: 'focused' | 'background' - placement?: { tabId?: string; leafId?: string } -} -``` - -The host canonicalizes the provider identity, binds it to the execution -namespace and canonical worktree, and signs a digest claim. Raw resume commands -do not cross a claim-capable boundary; compatibility-selected legacy and -unverified nested SSH paths retain their prior opaque command behavior. - -The execution owner performs one atomic operation: - -```text -claim absent -> reserve -> spawn -> publish live owner -> created -claim live -> prove PTY liveness -> return canonical owner -> adopted -claim unknown -> fail closed; do not spawn -claim conflict -> fail closed; do not spawn -``` - -Only an adopted owner may override the requested tab, leaf, handle, or PTY ID. -A fresh provider result must match the surface requested by the host. - -### Fresh launch - -`terminal.createAgentSession` accepts structured agent, prompt-delivery mode, -launch preferences, optional explicit agent arguments, and a cryptographically -random client operation ID. Draft prompts remain drafts; submitted prompts use -the normal startup-delivery path. Omitted agent arguments preserve host -defaults, while an explicit string is preserved as a client override and an -explicit null/empty value clears host argument defaults. Free-form client -environment variables are deliberately not accepted because PATH, loaders, and -other process authority remain host-owned. - -The runtime reserves the caller-scoped operation before any asynchronous -workspace or capability preflight, then fingerprints the host-resolved request -under the authenticated device identity: - -- same caller + operation ID + same fingerprint returns `replayed`; -- same caller + operation ID + different fingerprint fails; -- malformed, future-dated, expired, or over-capacity operations fail closed. - -The operation ledger is memory-bound and retained for 24 hours. Pre-spawn -failures release the entry for a safe retry. Once PTY creation commits, or the -provider reports an unknown physical outcome, the same rejected promise remains -as the replay fence. This handles response loss and ordinary reconnects to the -same running host. It does not claim exactly-once creation after the runtime -process itself restarts. - -Physical commit is the native-spawn boundary, not listener registration or -surface publication. The in-process provider reports it immediately after -`node-pty` returns; daemon and relay paths report it when their lower owner -returns from spawn/create-or-attach. Commit reporting is one-shot across these -layers. Any later error retains the operation fence because the PTY may already -exist even if publication failed. - -The runtime derives the execution-operation ID, tab ID, leaf ID, and terminal -handle deterministically from the authenticated operation. A daemon-backed -spawn derives a legacy-length session ID from that execution operation, so -`createOrAttach` returns the same PTY after a lost response without shrinking -the accepted worktree-ID boundary or skipping first-spawn setup. An SSH -provider performs a bounded read-only relay probe before structured work: - -- a relay advertising `agentSessionCreateOperationVersion: 1` receives the - operation ID and replays one successful spawn result for 24 hours; -- an older, malformed, or temporarily unreachable relay makes the host return - `agent_session_legacy_required`, after which the client sends its unchanged - legacy payload; -- negative relay capability results are not pinned, so an in-place upgrade is - observed on the next request. - -Relay operation-owned PTYs survive stale request contexts so the retry can -recover the same PTY and incarnation. Ordinary stale shell spawns keep the -existing cleanup behavior. - -## Claim identity - -The claim contains no raw provider session ID. A host-only signer hashes: - -- normalized agent/provider identity; -- canonical worktree scope; -- execution machine and principal; -- container/runtime namespace; -- a conservative provider-root bucket. The v1 implementation deliberately - merges account roots for an agent, which can produce a safe conflict but - cannot authorize duplicate execution. - -The wire binding includes a key ID, digest version, identity digest, worktree -scope digest, and agent kind. Owner state adds a random generation, PTY ID, and -canonical surface. - -Generation and PTY-incarnation guards prevent a late exit or liveness result -from releasing, retiring, or adopting a replacement owner that reused the same -PTY ID. - -## Recovery and failure semantics - -Before every claimed ensure, the controller stages complete listings from local -and registered SSH providers, validates every owner, and atomically replaces -the authoritative portion of its registry. Absent owners are pruned only for -providers whose listing is authoritative; disconnected scopes retain their -fence. Active reservations survive reconciliation. Valid metadata also rebuilds -PTY-to-provider routing. - -Controller-owned in-process fallback claims are intentionally not serialized -in ordinary local process listings. Their listing absence is therefore not -authoritative: the controller keeps the claim while the exact PTY incarnation -remains listed and releases it through the normal exit path. Daemon routers and -degraded providers likewise advertise listing authority only for a proven -PTY-to-provider route; an unknown ID never falls through to an unrelated -current/fallback provider for this decision. - -Recovery is fail closed: - -- owner PTY differs from the listed session: `agent_session_ownership_unknown`; -- two listings disagree about an identity or generation: - `agent_session_conflict`; -- the recorded provider is disconnected or unregistered: - `execution_owner_unavailable`; -- a claim-bearing spawn reaches a daemon/relay without execution-owner claim - protocol v2 (including PTY incarnation proof): - `agent_session_claim_unavailable`. Nested SSH routes that cannot construct a - claim are selected into legacy behavior before this boundary. - -Unknown liveness never means dead. A transient relay outage therefore retains -the claim and cannot authorize a replacement agent. - -Daemon adoption is attach-only. If the owner exits between liveness proof and -attach, the request fails rather than falling through to a new unclaimed shell. - -Serialized relay shell state intentionally omits provider claims. Spawn-based -revival creates a new shell and cannot inherit authority from the old process. - -## Renderer behavior - -Runtime-owned worktrees queue cached resume evidence through the same mounted -pane transport regardless of capability-cache timing. A capable host adopts or -creates one canonical owner; an old host or execution owner receives the exact -legacy launch. A cold or expired cache therefore cannot bypass authority or -remove the pre-change workflow. - -AI Vault resumes use provider metadata for agents with a structured identity, -including Antigravity conversation IDs and Pi transcript/session paths. If -metadata or host capability is absent, Orca preserves the prior opaque legacy -resume request instead of blocking the user. - -Background launches, quick launches, and mounted remote panes use -`terminal.createAgentSession` on capable hosts. Otherwise each call site sends -the exact pre-change `terminal.create` or `session.tabs.createTerminal` payload. -The common router calls legacy after only these safe outcomes: the host capability -is unavailable before dispatch; the structured RPC returns the stable -pre-side-effect `agent_session_legacy_required` code; or a replaced old host -returns `method_not_found`, proving it never recognized the structured request. -Timeouts, malformed results, and every other structured error never downgrade. - -Structured create/ensure responses record an exact -environment/worktree/provisional-tab to canonical-host-tab handoff. Snapshot -reconciliation removes a provisional pane only when its requested tab ID is -mirrored or that explicit handoff points to a host tab in the snapshot; agent -kind alone is never identity. This prevents an unrelated Claude/Codex session -from deleting a same-agent automatic-resume pane. The matched pane's pending -startup and automatic-resume claim are removed atomically, and the client -re-accepts the current host snapshot in case it arrived before the response. - -Every structured result is host-owned. If snapshot handoff destroys the -provisional transport while create/ensure is in flight, late completion cannot -close the canonical PTY even when reconciliation is still catching up. - -After the host accepts creation, a later tab-move or snapshot-refresh failure -still returns `created`. Reporting the launch as failed would invite a retry -with a new operation ID and could duplicate the fresh agent. - -## Exit and persistence lifecycle - -PTY exit is terminal authority. A generic persisted `sleeping` row is not a -reason to preserve a surface. Only an exact, runtime-owned stop transaction may -temporarily preserve the intentional handle-less surface. Otherwise the -runtime: - -1. verifies the PTY incarnation and identifies the exact worktree/tab/leaf; -2. removes that leaf from the host snapshot; -3. removes an empty parent tab; -4. repairs split groups, active group/tab, recent order, and layout; -5. removes the terminal binding from the persisted host workspace session and - advances that repo's host topology revision; -6. synchronously flushes that retirement before publishing the in-memory - absence; -7. rebases later renderer writes onto the host's current terminal membership, - so metadata and layout edits remain writable but missing/live panes cannot - be added or removed by a stale client. - -The durable fence is one monotonic revision per affected repo, not one record -per historical close or deleted worktree. Its storage is therefore proportional -to repos plus current terminal surfaces. A real host-admitted spawn advances -the revision when it adds a tab or leaf, allowing fresh terminals after a -retirement while an older renderer snapshot remains unable to revive the old -surface. Legacy per-pane tombstones are accepted for mixed-version recovery -and collapsed into the repo revision on the next normalized write. -The revision remains private to each execution host: renderer hydration and -writes omit it, avoiding collisions when different hosts contain the same repo -ID.

The existing 512 KiB file-upload chunk size in `src/renderer/src/runtime/runtime-file-client.ts` is safe after JSON plus encryption expansion; a chunk close to 1 MiB is not. -- The file-upload RPCs cannot be reused directly. They write worktree-relative files and then commit a rename; clipboard paste must call `saveClipboardImageBufferAsTempFile`, return a local or SSH temp path, and preserve the terminal repo's `connectionId`. -- Web session-tab sync intentionally mirrors pending host terminal surfaces so the tab model stays in parity, but it writes `ptyIdsByTabId[mirroredTabId]` only from `status: "ready"` surfaces. The status/filter helpers then bypass that liveness map with `isWebTerminalSurfaceTabId`, so pending mirrors look active. - -## Non-Goals - -- Do not raise the global WebSocket `maxPayload`; it protects all runtime traffic, including pre-auth and mobile sockets. -- Do not change sidebar grouping, labels, counts, pairing flow, terminal UI, or clipboard permission UI. -- Do not change local Electron clipboard behavior or the existing one-shot RPC contract. - -## Design - -1. Add bounded chunked clipboard-image RPCs. - - Keep `clipboard.saveImageAsTempFile` for small/old clients. - - Add `clipboard.startImageUpload`, `clipboard.appendImageUploadChunk`, `clipboard.commitImageUpload`, and `clipboard.abortImageUpload`. - - `start` takes `expectedBase64Length` and `connectionId`, rejects values over the existing 24 MiB base64 limit, records the target connection, and returns an unguessable upload ID. - - `append` takes `uploadId`, `offset`, and `contentBase64`; reject unknown IDs, out-of-order offsets, chunks above 512 KiB, invalid base64 characters, and cumulative length beyond `expectedBase64Length`. - - `commit` verifies the received length equals `expectedBase64Length`, validates the full base64 payload with the same rules as the one-shot RPC, calls `saveClipboardImageBufferAsTempFile` with the recorded `connectionId`, and deletes the upload state in `finally`. - - `abort` deletes the upload state and is idempotent. - - Bound server memory with a small max concurrent upload count and a TTL cleanup for abandoned uploads. Upload state is process-local; reconnects restart the paste instead of resuming. - -2. Switch paired browser image paste to the chunked path. - - After `navigator.clipboard.read()` and PNG conversion, return `null` for no image as today. - - Preflight `contentBase64.length` against the 24 MiB limit before starting an upload. - - Send 512 KiB base64 slices. This is below the 1 MiB encrypted frame cap after JSON and E2EE base64 expansion. - - Abort best-effort on append or commit failure. If `start` returns `method_not_found`, fall back to `clipboard.saveImageAsTempFile` only when the payload is below a conservative single-frame threshold; never send a large fallback frame. - -3. Tighten workspace activity liveness. - - Treat terminal workspaces as active only when `tabHasLivePty(ptyIdsByTabId, tab.id)` is true. - - Remove the blanket `isWebTerminalSurfaceTabId` active shortcut from `getWorktreeStatus` and `hasActiveWorkspaceActivity`. - - Keep browser tabs active without terminals. - - Keep fresh/retained explicit agent rows able to promote status to `permission`, `working`, or `done`; this is separate from terminal liveness. - -## Data Flow - -- Paste image: - - Browser paste command -> `navigator.clipboard.read()` -> PNG base64 in web preload memory. - - `clipboard.startImageUpload({ expectedBase64Length, connectionId })` -> upload ID. - - Repeated `clipboard.appendImageUploadChunk({ uploadId, offset, contentBase64 })`. - - `clipboard.commitImageUpload({ uploadId })` -> runtime saves temp image locally or on the SSH target -> terminal receives the temp path. - -- Workspace activity: - - Host `session.tabs.listAll` or subscription snapshot includes terminal surfaces. - - Web sync mirrors tabs but writes live PTY handles only for ready surfaces. - - Sidebar status/filter reads `ptyIdsByTabId` and browser tabs. - - Pending mirrored terminals with no PTY remain visible but do not count as active. - -## Edge Cases - -- Clipboard has no image or browser lacks `navigator.clipboard.read`: return `null`, no upload session. -- Clipboard read/permission/conversion fails: existing terminal paste error path reports the failure; the runtime socket should stay open. -- Non-PNG clipboard images may grow during PNG conversion; validate the post-conversion base64 length. -- Image exceeds 24 MiB base64: reject before upload and enforce again on the server. -- Chunk boundaries must preserve base64 validity; the 512 KiB chunk size is divisible by 4, and the final full payload validation catches padding errors. -- Append retry or concurrent append with the same upload ID: offset validation rejects duplicate, skipped, or out-of-order data. -- Multiple paired browser clients or windows paste at once: upload IDs isolate sessions and the concurrent-upload cap bounds memory. -- Append or commit fails: browser aborts best-effort; server TTL cleans abandoned state. -- SSH connection missing or drops during commit: commit fails, upload state is still deleted, and the paste path reports the error. -- Runtime restarts during upload: pending RPC fails; no resume is attempted. -- Pending host terminal surface later becomes ready: the next snapshot writes PTY handles and the workspace becomes active. -- Host closes a terminal or browser tab: the next snapshot removes the mirrored tab and stale PTY/browser handles before activity is recomputed. - -## Test Plan - -- Unit: `src/main/runtime/rpc/methods/clipboard.test.ts` for start/append/commit/abort, offset validation, invalid base64, size limit, TTL cleanup, commit cleanup on save failure, SSH `connectionId` forwarding, and concurrent upload isolation. -- Unit: `src/renderer/src/web/web-preload-api.test.ts` for chunk sequencing, 512 KiB max chunks, `method_not_found` small-payload fallback, no large fallback frame, and abort on append/commit failure. -- Unit: `src/renderer/src/lib/worktree-status.test.ts` and `src/renderer/src/lib/worktree-activity-state.test.ts` for pending mirrored terminal inactivity, ready mirrored terminal activity, browser-only activity, and explicit agent-row promotion. -- Focused run: `pnpm exec vitest run --config config/vitest.config.ts src/main/runtime/rpc/methods/clipboard.test.ts src/renderer/src/web/web-preload-api.test.ts src/renderer/src/lib/worktree-status.test.ts src/renderer/src/lib/worktree-activity-state.test.ts`. -- Type/lint: `pnpm typecheck`, `pnpm lint`. -- Paired-client validation: restart the host app, pair a real browser client, paste a screenshot large enough that the old one-shot RPC exceeded the 1 MiB encrypted frame cap into a local terminal and an SSH-backed terminal, confirm the runtime socket stays connected, then compare browser and host sidebar activity. - -## UI Quality Bar - -No layout changes. The paired browser sidebar should show active dots only for workspaces with live terminal PTYs, browser tabs, or explicit agent rows. Image paste should insert the generated temp image path into the terminal without connection-error toasts or DevTools runtime disconnect errors. - -## Review Screenshots - -1. Paired browser sidebar after hydration with inactive Done/Todo workspaces visible but not marked active. -2. Paired browser terminal after image paste, showing the generated temp image path inserted. -3. Host sidebar for the same session, showing matching active workspace state. - -## Rollout - -1. Add chunked clipboard RPC implementation and tests. -2. Switch web preload image paste to chunked upload and tests. -3. Tighten activity/status liveness helpers and tests. -4. Run focused tests, typecheck, and lint. -5. Validate in a paired Electron/browser session, including SSH paste, and capture the review screenshots. - -## Lightweight Eng Review - -- Scope: narrow to web clipboard transport and activity liveness. No global WebSocket limit, sidebar redesign, or local Electron clipboard changes. -- Architecture/data flow: web preload owns browser clipboard read and chunk sequencing; main runtime clipboard RPC owns upload session state and final temp-file save; sidebar helpers stay pure and consume the existing live-PTY map. -- Failure modes: oversized images must fail before a large frame is sent; abandoned uploads expire; failed append/commit paths clean up; pending host terminal mirrors do not inflate activity; SSH commit failures do not leak upload state. -- Tests: cover RPC lifecycle and bounds, web preload sequencing/fallback/abort, status/filter liveness, and real paired-client paste/sidebar parity. -- Performance/blast radius: chunking is not free. A max-size image is dozens of serialized runtime RPC calls and duplicates base64 in browser and main memory. The impact is limited to image paste by TTL, size, and concurrency caps. Activity changes affect sidebar filters, jump palette activity, and status dots. -- UI quality: no new chrome. Judge only sidebar parity, paste result, and absence of runtime disconnect/toast regressions. -- Screenshots: browser sidebar, browser terminal after paste, and matching host sidebar. -- Residual risk: clipboard permission and image conversion behavior are browser-dependent, so paired browser validation is required in addition to unit tests. diff --git a/docs/renderer-memory-profile-2026-06-01.md b/docs/renderer-memory-profile-2026-06-01.md deleted file mode 100644 index dbf3ee71dd5..00000000000 --- a/docs/renderer-memory-profile-2026-06-01.md +++ /dev/null @@ -1,171 +0,0 @@ -# Renderer Memory Profile, 2026-06-01 - -## Scope - -This profile investigated high Orca renderer memory while working in -`/Users/nwparker/orca/workspaces/orca/goal`.

The public - `/usr/local/bin/orca` shim pointed at a removed development app path, so it - failed before contacting the runtime. -- `orca tab list --worktree all --json` returned `tabs: []`.

Browser tabs were not the live-session memory source. The session had no - browser tabs and no browser guest renderer process. -2. The browser-pane retention fix is still useful: inactive worktree browser - webviews are now unmounted so Chromium can release guest renderers.

Resource Usage was using `app.getAppMetrics().memory.workingSetSize` for - Orca app buckets. On macOS this can count large shared Electron/Chromium - mappings and make the renderer look much larger than its private footprint. -4. The active terminal path was producing noisy previews from TUI redraws. This - explains the high active renderer churn observed during the profile, even - though the terminal memory buffers were already capped. - -## Changes Made - -- Browser panes now mount their backing webview only when the pane is active or - automation-visible. This sleeps inactive worktree browser guest renderers - without sleeping the main Orca renderer. -- Browser crash breadcrumbs now include webview counts, parked webview counts, - hidden webviews, and registered browser guest counts. -- The memory collector now prefers the existing host process RSS sweep for - Electron app bucket memory, falling back to Electron working-set data only - when a host row is missing. -- Terminal preview retention now applies carriage-return and backspace redraw - controls before appending text to the retained preview tail. - -## Validation - -- Browser overlay, webview registry, and crash diagnostics tests passed. -- Browser tab e2e tests passed. -- Memory collector tests passed, including host RSS preference and fallback - coverage. -- Runtime terminal tests passed for carriage-return and backspace redraw - normalization, plus the existing bounded partial-tail coverage. - -## Remaining Risk - -The current packaged Orca app was not running this worktree's patched code -during the live profile. The fixes are covered by unit and e2e tests, but the -next packaged build should be re-profiled under the same active Codex TUI load -to confirm the Resource Usage display and terminal previews match the expected -lower-churn behavior. - -## Follow-up: CLI Profiling Blocker - -Continuing the profile after this change confirmed the public -`/usr/local/bin/orca` command was still broken because it was a regular -generated launcher file pointing at a removed development build. The CLI -installer previously self-healed stale symlinks, but treated regular files as -conflicts. That meant Settings could not replace an Orca-owned stale launcher, -forcing profiling to use the packaged CLI fallback. - -The follow-up fix teaches the installer to recognize only generated Orca Unix -launcher files as stale and replaceable. Arbitrary regular files at the command -path remain conflicts. - -## Follow-up: Repeatable Memory Diagnostics - -The next profiling blocker was repeatability: collecting a useful memory sample -still required combining Resource Usage IPC, terminal lists, browser tab state, -and host process output by hand. This branch adds `orca diagnostics memory`, -which exposes the existing main-process memory collector through runtime RPC. - -The command returns the same `MemorySnapshot` shape used by Resource Usage when -run with `--json`, including host memory, Orca app process buckets, worktree -terminal memory, per-session process roots, and history samples. Text output -prints a compact point-in-time summary and the top worktrees by retained -terminal memory. - -## Follow-up: Agent-Browser Paintability Guard - -The browser parking fix depends on automation-visible panes staying paintable -without activating the user's worktree. The renderer bridge previously waited -for two animation frames before creating the automation visibility lease, so the -paint wait happened while the parked webview was still hidden. Non-screenshot -agent-browser commands could therefore start immediately after the lease was -created, before React had made the hidden pane paintable. - -The follow-up changes the order: create the automation visibility lease first, -then wait for paint while the pane is actually visible to automation. A -renderer-side timeout releases the lease if paint never arrives, so a hung RAF -does not pin an inactive browser pane indefinitely. - -## Follow-up: Browser Registration Readiness - -One remaining automation race was the wake path for parked or restored browser -tabs. Runtime browser commands asked the renderer to mount a hidden browser -pane, then waited a fixed 500 ms before reading the agent-browser tab registry. -On slow webview startup, that could still race `registerGuest` and make -agent-browser report no tab even though the tab was in the process of mounting. - -The follow-up extends the existing tab-registration wait from page-specific -creation to worktree/global wake flows. Runtime commands now wait for the -renderer's actual `browser:registerGuest` IPC before routing automation, with -the same timeout fallback used by tab creation. - -## Follow-up: Worktree Activation No-Op Fanout - -The next renderer-store check found that repeated activation of an already -active, already-reconciled worktree could still publish a new Zustand root state -because `setActiveWorktree` rebuilt `activeTabTypeByWorktree` even when its -stored value was unchanged. That woke every store subscriber, including session -persistence and runtime graph sync, for a visible no-op. - -The follow-up preserves the existing state reference when all derived active -fields, unread state, and first-activation bookkeeping are unchanged.

A catch may write an error only if its sequence - still owns that worktree, so a slow failure cannot overwrite a newer retry - or success. - - Add a focused renderer helper that accepts the captured - `SourceControlActionError` and the current branch name, then returns either - `null` or a model with raw/sanitized detail text, summary, details flag, - kind label, and AI prompt. - - The helper returns `null` unless the operation is `push`, `force_push`, - `publish`, or `sync` with the sync push-stage marker and - `isPushHookFailure(rawError)` passes. - - If the current branch is known and differs from the captured branch, hide or - clear the model instead of launching an agent with wrong branch context. - - Pass that single model to `useSourceControlAi` and `CommitArea`; neither - prop construction nor `CommitArea` should repeat the push-hook predicate. - -5. Use one generic recovery launcher for commit and push failures. - - Replace the separate commit and push launch files with - `source-control-ai-recovery-launch.ts`, or keep the old files as one-line - wrappers if import stability is cheaper. - - The generic launcher owns connection resolution, SSH/local agent discovery, - saved-agent validation, agent-args validation, agent selection, terminal - launch, focus, and success/failure toasts. - - Resolve connection without collapsing local and unresolved states: read - `const worktreeConnectionId = getConnectionId(worktreeId)`, use it when it - is a string or `null`, and only fall back to `sourceRepoConnectionId` when - the worktree lookup returns `undefined`. If the fallback is also - `undefined`, show the workspace-connection error instead of launching - locally. `null` means proven local; a string means SSH/remote. - - Validate saved CLI args before agent detection or terminal creation. On - Windows, keep using PowerShell-safe planning through - `planAgentCliArgsSuffix(..., 'powershell')`. - - Action-specific data is limited to action id, base prompt, empty-prompt - copy, unavailable-agent copy, and success copy. - -6. Keep the recovery hook thin. - - `use-source-control-recovery-ai.ts` builds the commit prompt, accepts the - already-derived push recovery prompt/model, keeps independent loading - flags, and calls the generic launcher. - - It should not import push-hook detection, resolve agents, or duplicate - launch plumbing. - -7. Extract and reuse the recovery UI. - - Reuse or replace the existing - `src/renderer/src/components/right-sidebar/source-control-fix-split-button.tsx` - rather than adding another split-button component. - - Move the dense recovery notice and Details dialog into focused renderer - modules named for source-control recovery. Avoid `helpers`, `utils`, and new - max-lines suppressions. - - Reuse the same notice/dialog component for commit and push recovery with - action-specific labels, summary, details, prompt, saved recipe, and launch - callback. - - Keep normal remote errors filtered out when a push recovery model is - rendered, so the user does not see both Push blocked and generic remote - error copy for the same failure. - -8. Retain `fixPushFailure` in the existing Source Control AI action model. - - The prototype already adds `fixPushFailure` to - `src/shared/source-control-ai-actions.ts`; keep it as a launch action like - `fixCommitFailure`. - - Verify default settings, normalizers, global settings rows, repository - override rows, labels, descriptions, and variable chips all include Push - failure fixes. - - Do not create a push-specific settings store or migration.

The parent path is charged per listing rather than -per entry because a listing's entries all share a single parent-path string; charging it per entry -multiplied it by the directory's width, so the 64 MiB cap tracked checkout depth instead of live -heap and rejected the layouts above once the worktree path passed ~58 characters. These are -admission limits, not post-allocation observations. - -The budget measures what the traversal is holding **right now**, not what it has ever seen.

A live cap depends only on directory -shape, so it rejects genuinely pathological layouts (one directory holding six figures of entries) -and nothing else. - -Top-level directory enumeration for the `du` path uses the same budget. A capacity error must not -fall through into the portable walker, because that would repeat an already rejected traversal. - -### Failure behavior - -- Desktop local scan: return an unavailable worktree row with the capacity error. `classifyError` - maps `WorkspaceSpaceScanCapacityError` to `unavailable` rather than `error`, because the workspace - is intact and readable, just too large to size safely. The Resource Manager renders that row as - "Unavailable" instead of "Failed". -- SSH relay scan: reject the bulk scan; the desktop provider converts it to an unavailable row. -- Generic `du` failure: use the bounded portable fallback. -- Cancellation: propagate the scan-cancelled error rather than converting it to a row failure. -- Missing or unreadable entries below the capacity limit: preserve existing partial-result - behavior. - -### Platform and workspace parity - -- macOS/Linux: one local `du` at a time; bounded Node fallback. -- Windows: one local bounded Node traversal at a time. -- WSL: retain `getLocalProjectWorktreeGitOptions` and its selected distro for worktree discovery; - UNC/native filesystem traversal uses the same local admission and capacity bounds. -- SSH: prefer the bulk relay scan; both the relay and the request-by-request compatibility fallback - use the shared capacity model. -- Folder workspaces: the synthetic main worktree passes through the same local limiter and scanner. - -## Data Flow - -1.

The helper must return no-op when the pointer is outside the container horizontally, the pointer is outside the vertical edge zones, or the container is already at the relevant scroll bound. -3. Add a small session refresh helper that replaces `worktreeDragSessionRef.current` with the latest `getWorktreeDragRectsForGroup(scrollRef.current, session.sourceGroupKey)` result and revalidates the latest groups: `worktreeDragGroups` must still contain the source group and `session.draggingWorktreeId`, and `worktreeDragUnitGroups` must still contain `session.reorderUnitDraggedIds` for the same `sourceGroupKey`. Do not require every `session.reorderDraggedIds` entry to be in the source group, because the existing multi-select/lineage reorder path filters those ids during commit. If the source group or reordered unit ids disappear, clear the drag instead of committing stale ids. -4. Track autoscroll animation frame ids separately from `WorktreePointerDrag.frameId`. The existing `frameId` is for preview/drop flushing; sharing it would make it easy to cancel the wrong work or skip a needed preview update. -5. Pointer drag path: - - start autoscroll only after `beginWorktreePointerDrag()` promotes the drag to active; - - each autoscroll frame reads the latest `drag.currentX/currentY`; - - apply `container.scrollTop = nextScrollTop` only when it changes; - - call `markScrollMovement()` before or immediately after the scroll write instead of `markDirectScrollInput()`; - - refresh source-group rects from the mounted DOM before recomputing a drop; if the virtualizer has not rendered the newly exposed rows yet, keep the current null-drop behavior for that frame; - - schedule `scheduleWorktreePointerDragFrame(drag)` after a scroll write so the preview line is recomputed against the new `scrollTop` and refreshed rects. -6. Native drag path, if it is kept or re-enabled: - - store the latest native drag-over `clientX/clientY` in a small ref while a `WorktreeDragSession` exists; - - run a separate autoscroll frame loop from `onDragOver`; - - after a scroll write, refresh source-group rects, recompute the native drop preview from the stored `clientY`, and update `worktreeDragState`; - - set `event.dataTransfer.dropEffect = 'move'` only inside real `dragover`/`drop` event handlers when the current drop is valid. A RAF callback cannot update the native drag cursor/effect; it can only update sidebar preview state until the next native drag event. -7.

Refresh rects from `[data-worktree-drag-id]` for the source group only, and tolerate a frame where the virtualizer has not mounted newly visible rows yet. -- Source mutations: if the dragged worktree, source group, or reorder unit disappears during drag, clear the drag instead of committing against stale ids. -- Concurrent ordering changes: final drop should use the latest `worktreeDragGroups`/`worktreeDragUnitGroups` already captured by React callbacks, but the source group and reordered unit ids must be revalidated before commit.

A boundary candidate is emitted only when it covers the requested row, has at least two non-empty row fragments, and the fully joined text passes the existing path-start predicate. It may end at the first proper prefix slice of a mixed row or at the last available whole-fragment row; the latter is limited to whitelisted incomplete starts and is skipped when whole-row reconstruction already emitted the same text.

+/**
+ * Paired remote server: a revealed remote terminal must stay interactive
+ * without a tab flip.
+ *
+ * Topology: headed Orca desktop host (remote server) + a separate paired Orca
+ * desktop client — the "connect to Windows 2, open an old workspace" shape.
+ *
+ * Oracle (the reported symptom verbatim): type into the revealed pane and see
+ * the echo paint live. "Paints only after switching to another terminal and
+ * back" is the failure, so each scenario records both.
+ *
+ * The decoy tabs are load-bearing, not scenery. Pre-fix, handleClose never runs,
+ * so closeIfIdle is the only remaining release path and it needs zero streams —
+ * a sibling stream is what keeps the wedged multiplexer alive and the pre-fix
+ * state red. Each scenario asserts its flip decoy is still mounted at the reveal
+ * so that invariant cannot quietly lapse and turn this green.
+ *
+ * Run:
+ *   pnpm exec playwright test \
+ *     tests/e2e/paired-remote-terminal-parked-reveal-interactivity.spec.ts \
+ *     --config tests/playwright.config.ts --project electron-headless --workers=1

+# E2E Test Plan: SSH config host picker (`import-ssh-config-does-nothing`)
+
+## Branch summary
+
+Users can open **Fill from ~/.ssh/config…** on the add-SSH-host dialog, pick a
+Host alias, and get the form prefilled from `ssh -G` resolution. Bulk sync is a
+secondary **Add all N to Orca** action (no re-adopt). Settings → SSH → **Import**
+remains the deliberate re-adopt path.
+
+Commits under test (vs main):
+
+- `bd0b594dee` feat(ssh): add SSH config host picker for add-host form
+- `dc8339369a` fix(ssh): import filter preservation and label fallback
+- `5982c8108f` fix(ssh): harden config picker import, alias folding, host targeting
+- `5cfb6369e7` refactor(ssh): centralize host result limit / folder group helper
+
+## Already covered (do **not** re-test in E2E)
+
+| Area | Where |
+|------|--------|
+| `listConfigHosts` / `resolveConfigHost` IPC registration | `src/main/ipc/ssh.test.ts` |
+| Search, result limit, suppressed aliases, alreadyInOrca | `ssh-config-host-picker.test.ts` |
+| Generation guard, freeze-while-resolving, late resolve | `AddRemoteHostDialog.config-picker.test.tsx` |
+| Bulk `importConfig()` without `reAdopt` | `add-remote-host-ssh-actions.test.ts` |
+| Alias folding / duplicate save check | `ssh-target-duplicate.test.ts` |
+| `configured-only` host registry / setup fail-closed | unit tests in shared + project-host-workspace-target |
+| Settings modal viewport stability | `ssh-host-form-modal.spec.ts` |
+
+E2E is reserved for real Electron HOME isolation, real `~/.ssh/config` parse,
+real `ssh -G` resolve, and user-visible DOM outcomes.
+
+## Harness requirements
+
+1. **Isolated HOME** — E2E already sets `HOME` to `{userDataDir}/home`. Seed config with:
+   ```ts
+   const home = await electronApp.evaluate(({ app }) => app.getPath('home'))
+   mkdirSync(path.join(home, '.ssh'), { recursive: true, mode: 0o700 })
+   writeFileSync(path.join(home, '.ssh/config'), configBody, { mode: 0o600 })
+   ```
+2. **Unique aliases** — prefix Host entries and Orca labels with
+   `e2e-ssh-cfg-${Date.now().toString(36)}-…` so workers never collide; clean up
+   via `window.api.ssh.removeTarget` in `afterEach` by label/configHost prefix.
+3. **Open the picker dialog** (not Settings `SshTargetForm` — that form has no
+   config picker). Path:
+   - Open **Add Project** (sidebar / landing control)
+   - Host combobox → **Add remote host** → **Add SSH host**
+   - Dialog title **Add SSH host** with link **Fill from ~/.ssh/config…**
+4. **Assertions** — DOM only (`getByRole`, `toHaveValue`, visible badges/toasts).
+   Store/API only for setup/cleanup/seeding existing targets.
+5. **Prereq** — OpenSSH client on PATH (`ssh -G`). macOS/Linux CI has it; skip
+   or soft-fail only if `ssh -G` is unavailable (document in test comment).
+
+## Spec file
+
+`tests/e2e/ssh-config-host-picker.spec.ts`  
+Reuse patterns from `ssh-host-form-modal.spec.ts` (session ready, target cleanup,
+announcement dismiss). Prefer small local helpers over new shared modules unless
+helpers would be reused elsewhere.
+
+Optional second file if the Settings Import case grows:  
+`tests/e2e/ssh-config-import-settings.spec.ts` — otherwise keep Import in the same file.
+
+---
+
+## Cases (must ship)
+
+### P1 — Empty config empty state
+
+| | |
+|--|--|
+| **Setup** | Do not create `~/.ssh/config` (or write empty file). |
+| **Steps** | Open Add SSH host → Fill from ~/.ssh/config… |
+| **Expect** | Dialog title **Choose from ~/.ssh/config**; body **No hosts in ~/.ssh/config**; **Add all to Orca** disabled; **Back** returns to form. |
+
+### P2 — Seeded hosts listed with summary lines
+
+| | |
+|--|--|
+| **Setup** | Write config with ≥2 concrete Hosts, e.g. `e2e-alpha` / `e2e-bravo` with HostName, User, Port. |
+| **Steps** | Open picker. |
+| **Expect** | Host list `SSH config hosts` shows both aliases; subtitle `user@hostname:port`; button **Add all 2 to Orca** enabled. |
+
+### P3 — Select host prefills form (and Save persists)
+
+| | |
+|--|--|
+| **Setup** | Config Host `e2e-prod` → HostName `prod.example.test`, User `deploy`, Port `2222`. |
+| **Steps** | Pick `e2e-prod` → wait for form → click **Save**. |
+| **Expect** | After pick: Host/alias field = `prod.example.test`, Username `deploy`, Port `2222`, Label `e2e-prod` (or alias); optional toast *Filled from e2e-prod*; Identity file may stay empty with config hint. After Save: dialog closes; target appears in Settings → SSH (or listTargets shows matching host). |
+
+### P4 — Filter narrows list
+
+| | |
+|--|--|
+| **Setup** | Hosts `e2e-alpha`, `e2e-bravo`. |
+| **Steps** | Open picker; filter `bravo`. |
+| **Expect** | Only bravo row; alpha gone; **No matching hosts** if filter is nonsense. |
+
+### P5 — Already-in-Orca badge + disabled row
+
+| | |
+|--|--|
+| **Setup** | Config hosts alpha + bravo. Seed Orca target with `configHost`/`label` matching alpha (via `ssh.addTarget`). |
+| **Steps** | Open picker. |
+| **Expect** | Alpha shows **In Orca** badge and is not clickable; bravo still selectable; **Add all 1 to Orca** (not 2). |
+
+### P6 — Add all N to Orca imports new hosts only
+
+| | |
+|--|--|
+| **Setup** | Config with 2 new hosts; no Orca targets for them. |
+| **Steps** | **Add all 2 to Orca** → wait for success toast / return to form or list refresh. |
+| **Expect** | Both targets exist (DOM in Settings SSH and/or listTargets); re-open picker shows **All hosts already in Orca** / both **In Orca**. |
+
+### P7 — Add all does **not** re-adopt deleted hosts
+
+| | |
+|--|--|
+| **Setup** | Config with alpha + bravo; Add all → remove alpha via API (creates suppress tombstone). |
+| **Steps** | Re-open picker; note count; optionally click Add all again. |
+| **Expect** | Alpha absent from picker (suppressed) or not re-created; only new hosts counted; `listTargets` still lacks deleted alpha after second Add all. |
+
+### P8 — Back discards pending pick path
+
+| | |
+|--|--|
+| **Setup** | Seeded config. |
+| **Steps** | Open picker → **Back** without selecting. |
+| **Expect** | Form fields still empty (Host blank); no filled toast. |
+
+### P9 — Settings Import re-adopts (contrast with P7)
+
+| | |
+|--|--|
+| **Setup** | Same as P7 after delete. |
+| **Steps** | Settings → SSH → **Import** (explicit reAdopt path). |
+| **Expect** | Deleted config host reappears as an Orca target; toast sync count ≥ 1. |
+
+---
+
+## Nice-to-have (only if cheap after P1–P9)
+
+- **N1** ProxyCommand / JumpHost: pick host with ProxyJump → Advanced opens and jump field filled (proves advanced prefill + `preferAdvancedOpen`).
+- **N2** Case-insensitive alias: config `Prod`, existing label `prod` → **In Orca**.
+- **N3** Empty Identity file hint visible after config fill.
+
+Skip: 100-host truncation, resolve races, GSSAPI system-default, composer host-availability fail-closed (unit-covered).
+
+## Out of scope
+
+- Real SSH connect / relay / PTY
+- Docker SSH fixtures
+- Web client stub paths (`listConfigHosts` returns empty)
+- i18n non-English
+
+## Implementation status (done)
+
+| Case | Spec |
+|------|------|
+| P1 empty state | `ssh-config-host-picker.spec.ts` |
+| P2 list + Add all enabled | `ssh-config-host-picker.spec.ts` |
+| P3 select + Save (+ N3 identity hint) | `ssh-config-host-picker.spec.ts` |
+| P4 filter | `ssh-config-host-picker.spec.ts` |
+| P5 In Orca badge / count | `ssh-config-host-import.spec.ts` |
+| P6 Add all imports | `ssh-config-host-import.spec.ts` |
+| P7 no re-adopt after delete | `ssh-config-host-import.spec.ts` |
+| P8 Back without select | `ssh-config-host-picker.spec.ts` |
+| P9 Settings Import re-adopts | `ssh-config-host-import.spec.ts` |
+
+Shared helpers: `tests/e2e/helpers/ssh-config-host-picker.ts`
+
+### Product fix required for E2E (and real HOME isolation)
+
+OpenSSH resolves the default user config via **getpwuid**, not `$HOME`. E2E
+sets an isolated `HOME`, so `loadUserSshConfig` (Node `os.homedir()`) and
+`ssh -G` could disagree. `src/main/ssh/ssh-g-config-resolution.ts` now passes
+`-F /.ssh/config` when the HOME config path exists and differs from the
+passwd home. Normal installs (HOME = passwd home) are unchanged.
+
+## Suggested run command

+```bash
+pnpm exec electron-vite build --mode e2e
+SKIP_BUILD=1 pnpm exec playwright test \
+  tests/e2e/ssh-config-host-picker.spec.ts \

+/**
+ * E2E regression for #8372 — the status-bar CLI session count froze after a Manage Sessions kill.
+ *
+ * `pty:management:killOne` tears a session down with `adapter.shutdown()`. The daemon only fans
+ * `exit` to the clients attached to that session, so when the killed session belongs to *another*
+ * daemon client (a previous app generation, `orca serve`, a second Orca client) this window's main
+ * process never emits `pty:exit`. The status-bar chip is an event-sourced cache: with no lifecycle
+ * event and no interval it kept painting the pre-kill count until the Resource Manager popover was
+ * opened — and opening the popover refreshes, which is exactly why this spec never opens it.
+ *
+ * The spec creates that foreign session the way the daemon protocol really does it: a second
+ * DaemonClient connected to the app's own daemon socket. The app then sees three live sessions
+ * (its two panes plus the foreign one), the third of which Manage Sessions lists as unbound.
+ *
+ * Visible evidence: the `>_ N` number in the status bar. It must go 3 -> 2 after the row kill,
+ * with the popover closed the whole time.
