+# Why: proves what happens to terminal sessions across a real Windows app update
+# by installing one released version, updating to another, and asserting on the
+# packaged artifacts (daemon survival, terminal interactivity, zero console
+# flashes). This MUST run on a disposable CI Windows: electron-builder's oneClick
+# installer uninstalls the registry-registered copy of the app before every
+# install, so running the harness on a machine with a real Orca install would
+# delete it. A fresh runner has no Orca registered, so it is the only safe home
+# for install-based testing. Manual dispatch only.
+
+# Why: workflow_dispatch only works once a workflow is on the default branch.
+# To exercise this from the unmerged feature branch WITHOUT touching main, a
+# push trigger scoped to that exact branch runs the workflow from the branch's
+# own tree. The paths filter keeps it to harness/workflow edits so ordinary
+# commits don't spend 30 min of Windows runner time. Push runs have no inputs,

+# inner binaries (Orca.exe, node-pty *.node, DLLs — see issue #7785) requires
+# a two-request flow: sign the unpacked PE files first, then build the NSIS
+# installer from the signed tree, then sign the installer. This workflow
+# rehearses that entire flow from a branch, end to end, without publishing
+# anything — so the release pipeline on main is never at risk while we verify.
+#
+# Runs only via manual dispatch. Use the test-signing policy for iteration
+# (auto-approved test certificate) and release-signing to rehearse the
+# production flow (requires manual SignPath approvals). Rehearsed successfully
+# with test-signing (run 28987534795) and release-signing (run 28988432001).

+This is enforced in CI by `pnpm check:max-lines-ratchet` (`config/scripts/check-max-lines-ratchet.mjs`). Files already over the limit are grandfathered in `config/max-lines-baseline.txt`; that list may only **shrink**. Adding a new suppression fails the build. If you remove a suppression (great — split it!), run `pnpm check:max-lines-ratchet --prune` to drop its baseline line.

+; Clean up the relocated terminal daemon on a REAL uninstall.
+;
+; Why: the daemon host is deliberately copied to a distinct image name
+; (orca-terminal-daemon.exe) under %LOCALAPPDATA%\Orca\daemon-host so that app
+; UPDATES cannot kill it — that relocation is what keeps terminals alive across
+; updates. The same design means a normal uninstall's process sweep and file
+; removal both miss it, leaving an orphaned daemon plus its runtime copy behind.
+;
+; The ${isUpdated} guard is essential: electron-builder runs this uninstaller as
+; part of uninstallOldVersion on EVERY update, and killing the daemon there would
+; defeat the whole feature. Only clean up on a genuine uninstall.
+;
+; The image name and the LOCALAPPDATA folder name must stay in sync with
+; DAEMON_HOST_EXE_NAME and LOCAL_HOST_ROOT_NAME in
+; src/main/daemon/daemon-host-relocation.ts.

+/**
+ * Boots the BUILT terminal daemon (out/main/daemon-entry.js) under plain Node —
+ * the exact way production forks it (ELECTRON_RUN_AS_NODE = a plain-Node
+ * process) — and asserts it starts, serves a real PTY, and stops.
+ *
+ * Why this exists: native-smoke CI (and packaging) went green while
+ * v1.4.129-rc.1 shipped a daemon that exited code 1 at module load because an
+ * electron `require` leaked into its bundle graph. Nothing executed the built
+ * entry under plain Node, so the outage was invisible until an adopted old
+ * daemon died in the field. This runs on every PR that touches the daemon.
+ *
+ * Hard assertions (fail the job):
+ *   - the daemon signals `{ type: 'ready' }` over IPC within the timeout, and
+ *   - it terminates when asked (no hang / zombie).
+ * Best-effort (logged skip, never fails): an end-to-end `ptySpawnHealth` RPC,
+ * because node-pty spawn can be flaky on constrained CI runners.

+# SSH Typing Latency Under Relay Load
+
+Date: 2026-07-06
+
+## Symptom
+
+Typing in an SSH-host terminal can become extremely slow (hundreds of ms to
+seconds per echoed keystroke) while other SSH work is active — file previews,
+source-control refresh, search. A quiet SSH shell stays snappy, which made the
+reports look unreproducible.
+
+This is distinct from the local warm-switch lag documented in
+`terminal-switch-typing-lag-investigation.md` (daemon `listSessions()`
+snapshot cost — already fixed; `TerminalHost.listSessions()` is now
+metadata-only via `getAppliedSize()`).
+
+## Root Cause
+
+The relay and the Electron client share ONE ordered SSH channel for all
+JSON-RPC traffic: PTY input/output, file streams, git responses, search, port
+scans. Two mechanisms turned bulk traffic into typing latency:
+
+1. **Relay-side head-of-line blocking (primary).** The `fs.readFileStream`
+   pump (`src/relay/fs-handler-file-read.ts`) wrote every 256KB chunk (~340KB
+   framed) into the relay's stdout as fast as local disk reads completed,
+   ignoring the `write() === false` backpressure signal. A 10MB preview
+   enqueued ~13.6MB into the pipe at once; a `pty.data` echo emitted
+   mid-stream queued behind ALL of it. At 2MB/s WAN that is multiple seconds
+   of echo delay per open file. The reproduced measurement: 4,195,592 bytes
+   (the entire remaining 3MB test file, framed) queued ahead of one echo
+   frame.
+
+2. **Client-side O(n²) frame buffering (secondary).** `FrameDecoder.feed()`
+   in both `src/main/ssh/relay-protocol.ts` and `src/relay/protocol.ts` did
+   `Buffer.concat([buffered, chunk])` per data event, re-copying the whole
+   backlog for every ~32KB TCP chunk — ~2MB of memcpy per 340KB frame,
+   ~80MB per 10MB file — on the Electron main thread, delaying `pty:write`
+   IPC dispatch and echo delivery to the renderer.
+
+## Fix
+
+- **Bulk lane with sink backpressure** (`RelayDispatcher.notifyBulk`):
+  `fs.streamChunk` frames are serialized per client and each send waits for
+  the sink's `drain` when `write()` returns `false`. Interactive frames
+  (`pty.data`) still use plain `notify()` and are admitted immediately —
+  because the bulk lane keeps the outbound buffer at ~1 frame, an echo jumps
+  ahead of every not-yet-admitted chunk. Sinks (`relay.ts` stdout + Unix
+  socket clients) surface `write()`'s boolean and a one-shot
+  `waitWriteDrain`; every death path (EPIPE, stdin end, detach, dispose)
+  flushes parked waiters so a pump can never hang on a dead pipe.
+
+- **Credit-based flow control** (`fs.streamAck`): the client requests
+  streams with `flowControl: 'ack'` and acks each processed chunk; the relay
+  caps unacked chunks at `STREAM_ACK_WINDOW_CHUNKS = 4` (~1MB raw). This
+  bounds in-flight bulk bytes even past the relay's own pipe (sshd/TCP
+  buffers) and paces the relay's base64/JSON encode loop so incoming
+  keystroke frames get event-loop turns. A parked pump wakes on ack, cancel,
+  release, client detach, and a 1s staleness recheck.
+
+- **Cross-version compatibility**: old client + new relay → no
+  `flowControl` param → legacy unpaced pump (still drain-bounded, which is
+  transparent). New client + old relay → `fs.streamAck` is an unknown
+  notification and is silently ignored. `STREAM_CHUNK_SIZE` (256KB) is
+  intentionally unchanged — both sides bake it into chunk offset math, so
+  changing it would corrupt cross-version streams.
+
+- **FrameDecoder rewrite** (both mirrored protocol files): chunk-list
+  buffering; each frame is assembled exactly once (one copy) instead of
+  re-concatenating the backlog per feed.
+
+## What Stays Fast / Unchanged
+
+- Relay PTY output batching (interactive echo fast path in
+  `src/relay/pty-handler.ts`) is untouched.
+- No `listSessions()` / provider inventory was added anywhere near typing,
+  focus, switch, resume, resize, or render paths.
+- Remote file streaming correctness: per-chunk length checks, chunk-count and
+  byte-count invariants, cancel paths, and the 12MB round-trip integration
+  test all pass unchanged.
+
+## Regression Coverage
+
+- `src/relay/fs-stream-pty-echo-backpressure.integration.test.ts` — real
+  mux ↔ dispatcher ↔ FsHandler over a congestible in-memory pipe; asserts
+  deterministic BYTE bounds (not wall-clock): echo queues behind < 2 framed
+  chunks when congested (pre-fix: whole file), ack window caps in-flight
+  chunks, legacy no-ack clients still get complete streams.
+- `src/relay/fs-handler-stream.test.ts` — pump parks at the ack window,
+  resumes per ack, and releases its file handle when cancelled while parked.
+- `src/relay/dispatcher.test.ts` — notifyBulk semantics: drain gating,
+  per-client targeting, dispose releases parked senders, interactive
+  notify() not gated behind a stalled bulk lane.
+- `src/main/ssh/relay-protocol.test.ts` — decoder byte-at-a-time boundary
+  straddling, oversized-frame resync across odd chunk sizes, and a
+  no-`Buffer.concat`-during-feed guard that locks out the O(n²) shape.
+- `tests/e2e/ssh-docker-relay-perf.spec.ts` — new "busy relay" scenario:
+  types while two 8MB remote file-read loops and a git.status loop run;
+  budgets median < 500ms, worst < 2000ms. (On loopback Docker the pre-fix
+  HOL is only tens of ms — the in-process byte-bound test is the
+  authoritative red/green; the e2e guards the end-to-end wiring.)
+
+## Residual Gaps
+
+- **Large single-frame responses**: `git.*` responses (stdout capped at
+  `MAX_GIT_BUFFER` = 10MB → ~13MB framed) and other request/response results
+  are one atomic frame on the wire; a huge diff can still delay an echo by
+  its own transfer time. Fixing this requires response chunking (a protocol
+  change); bounded by the 16MB `MAX_MESSAGE_SIZE`.
+- **Outbound direction**: a large `fs.writeFile` request frame (client →
+  relay) can queue ahead of keystroke `pty.data` frames on `channel.stdin`.
+  Same shape, opposite direction, rarer trigger (saving a large remote file
+  while typing).
+- `pty.ackData` flow control for PTY output remains unenforced
+  (`src/relay/pty-handler.ts` — "not yet enforced"); PTY output floods are
+  already paced by the relay's 8ms batch/16KB slice scheduler.

+# Source Control Push Failure AI Recovery
+
+## Problem
+
+Push, force-push, publish, and sync push-stage failures flow through the shared
+remote operation formatter in `src/renderer/src/lib/source-control-remote-error.ts:94`
+and the editor-store toast paths in `src/renderer/src/store/slices/editor.ts:3716`
+and `src/renderer/src/store/slices/editor.ts:3821`. A local pre-push hook or
+lint hook is not an auth, protected-branch, or transport problem, so generic
+remote guidance sends the user in the wrong direction.
+
+PR #7787 proves the behavior is useful, but the prototype needs tightening before
+it is maintainable:
+
+- `src/renderer/src/components/right-sidebar/SourceControl.tsx:1938` and
+  `src/renderer/src/components/right-sidebar/SourceControl.tsx:5799` repeat
+  push-failure predicates and feed live branch/file state into a prompt that says
+  "at failure time".
+- `src/renderer/src/components/right-sidebar/use-source-control-recovery-ai.ts:63`
+  imports push detection again instead of consuming one derived recovery model.
+- `src/renderer/src/components/right-sidebar/source-control-ai-commit-failure-launch.ts:24`
+  and `src/renderer/src/components/right-sidebar/source-control-ai-push-failure-launch.ts:24`
+  are copied launch flows with action-specific copy.
+- `src/shared/source-control-commit-failure-agent-command.ts:6` and
+  `src/shared/source-control-push-failure-agent-command.ts:6` are identical
+  command-template builders.
+- `src/renderer/src/components/right-sidebar/source-control-fix-split-button.tsx:21`
+  already contains a reusable split button, while `SourceControl.tsx:6415`
+  carries a second inline version.
+- `src/renderer/src/lib/source-control-remote-error.ts:148` currently treats
+  any `isSync` error as push-like for hook detection. `syncBranch` calls the
+  formatter for fetch, upstream-status, pull, and push failures, so the renderer
+  cannot prove a sync error came from the push stage without an explicit marker.
+- `src/renderer/src/components/right-sidebar/SourceControl.push-failure-recovery.test.ts:2`
+  imports prompt helpers through the large React module instead of shared prompt
+  modules.
+
+## Goal
+
+Add first-class recovery for pre-push hook failures without growing a parallel
+push-only subsystem:
+
+1. Toasts for push, force-push, publish, and sync push-stage failures say
+   "blocked" for detected pre-push or lint-hook output.
+2. Source Control shows a concise Push blocked panel with Details and AI Fix
+   only for a failure snapshot that is both push-like and hook-like.
+3. AI Fix launches the configured `fixPushFailure` Source Control action with a
+   safe, provider-neutral prompt.
+4. Commit-failure recovery and push-failure recovery share launch,
+   command-template, split-button, and dense error-panel primitives.
+
+## Non-goals
+
+- Do not fix server-side pre-receive hooks, hosted CI failures, or provider-side
+  protected-branch failures from this entry point.
+- Do not bypass hooks, add `--no-verify`, push from the launched agent, create a
+  PR, or assume GitHub-specific terminology.
+- Do not add app-wide persistence for this transient failure panel.
+- Do not redesign the Source Control panel or the Source Control AI settings
+  model.
+- Do not fold unrelated launch surfaces such as checks recovery into this change
+  unless a tiny shared helper is already needed for commit/push recovery.
+
+## Design
+
+1. Keep push-hook detection and prompt building in shared code.
+   - `src/shared/source-control-push-failure.ts` owns normalization, bounded
+     scanning, summary text, Details eligibility, prompt truncation, prompt
+     rules, and changed-file list bounding.
+   - Detection must stay conservative: explicit `pre-push`/`prepush`,
+     `hook declined to push`, hook-runner output in push context, or lint output
+     in push context. Auth, non-fast-forward, protected branch, pre-receive,
+     submodule, and generic transport failures stay on the existing remote-error
+     path.
+   - Keep the output scan bounded at 64 KiB and the prompt failure-output
+     section bounded. Also cap prompt file lines to a small constant with an
+     omitted-count line; do not rely on the git-status cap, which is far too high
+     for prompt context.
+
+2. Make remote-error formatting sync-stage aware.
+   - Extend `RemoteOperationErrorOptions` with an explicit push-stage flag for
+     sync, for example `isSyncPushStage`.
+   - Gate push-hook classification on `isPush`, `isForcePush`, `publish`, or
+     `isSyncPushStage`; do not use bare `isSync` as evidence of a push failure.
+   - In `syncBranch`, pass the push-stage flag only inside the two inner
+     `pushRuntimeGit` catch blocks. The outer fetch, upstream-status, and pull
+     catches still pass `isSync` for Sync-shaped generic copy but must not render
+     blocked hook copy.
+   - Carry the same push-stage fact back to the renderer, either by tagging the
+     thrown `Error` with a narrow exported marker or by wrapping it in a typed
+     error that preserves the original message/cause. `SourceControl` must set
+     `syncPushStage` only from that marker, not from `kind === 'sync'` plus
+     hook-like stderr.
+   - Keep submodule push messages before hook detection so submodule guidance
+     remains more specific than AI recovery.
+
+3. Replace one-off command builders with one shared recovery command builder.
+   - Add a shared builder that accepts `{ actionId, promptOverride,
+     commandInputTemplate, basePrompt }` and renders the existing Source Control
+     AI command template for launch actions.
+   - Keep compatibility exports for commit and push helpers if nearby tests or
+     call sites still use those names, but make them wrappers over the generic
+     builder.
+   - Move prompt-builder tests to import from shared modules, not
+     `SourceControl.tsx`.
+
+4. Capture and derive push recovery state once.
+   - Extend `SourceControlActionError` with the raw error, a push-stage marker
+     for sync failures, the branch name at failure time, a bounded status-entry
+     snapshot at failure time, and a per-worktree sequence token.
+   - `runRemoteAction` clears the worktree's previous error and increments its
+     sequence before starting. 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. Existing
+     `normalizeSourceControlAiSettings` hydrates missing action defaults.
+
+## Data Flow
+
+- User clicks Push, Force Push, Publish Branch, or Sync.
+- `runRemoteAction` clears that worktree's previous remote error, records a new
+  sequence token, and starts the editor-store remote action.
+- Git push fails and throws.
+- `pushBranch` or sync's inner push-stage catch calls
+  `resolveRemoteOperationErrorMessage` with push-like options. Sync fetch, pull,
+  and upstream-status failures do not pass the push-stage flag.
+- Sync's inner push-stage catch marks the rethrown error as push-stage so
+  `runRemoteAction` can preserve `syncPushStage` in the captured snapshot.
+- The formatter classifies hook output before auth/transport fallbacks only for
+  push-like options and shows blocked toast copy.
+- `SourceControl` catches the same error, and if the sequence still owns the
+  worktree, stores `{ kind, rawError, message, syncPushStage, branchName,
+  entriesSnapshot }`.
+- The push recovery helper derives one `pushRecovery` model from that snapshot.
+- `CommitArea` renders normal remote errors or the Push blocked recovery notice.
+- AI Fix builds the `fixPushFailure` command input and launches the selected
+  agent in the owning local or SSH runtime.
+
+## Edge Cases
+
+- Auth, missing repo, protected-branch, pre-receive, non-fast-forward, and
+  transport failures must not show the Push blocked panel.
+- Submodule push errors keep their existing specialized messages before
+  push-hook detection.
+- Sync failures from fetch, upstream-status, or pull stages must not show Push
+  blocked, even if stderr contains words like "lint" or "hook".
+- Create PR intent remote failures use the same `runRemoteAction` plumbing; if
+  CommitArea is not visible, blocked toast copy is still required but no hidden
+  panel work is needed.
+- A newer remote operation for the same worktree must clear stale recovery state
+  immediately and prevent an older in-flight failure from writing after it.
+- Switching worktrees or branches must not show another worktree or branch's
+  push failure.
+- External edits or another Orca window may make the failure stale. Do not add
+  cross-window persistence for this feature; rely on local retry/remount/branch
+  mismatch clearing and list this as residual risk.
+- Source Control AI hidden for a repo still shows the blocked notice and Details;
+  it hides AI Fix.
+- SSH worktrees must detect and launch agents on the owning connection, not a
+  local fallback.
+- Windows launch planning must continue to use PowerShell-safe agent args.
+- Very large hook output and very large changed-file sets must be bounded before
+  prompt generation.
+- ANSI/control output must not leak into summaries or Details comparison logic.
+  Details may show sanitized text while preserving enough line breaks for
+  debugging.
+- Empty custom command templates must stay empty so the launcher rejects them
+  with a clear settings error.
+- Prompt text must treat file paths, branch names, and hook output as data, not
+  instructions.
+
+## Test Plan
+
+- Shared unit tests:
+  - `src/shared/source-control-push-failure.test.ts` covers detection positives,
+    auth/protected/pre-receive/non-fast-forward negatives, ANSI/control
+    stripping, bounded scanning, details comparison, prompt output truncation,
+    prompt file-list capping, and provider-neutral prompt rules.
+  - Shared command-template tests cover the generic recovery builder plus
+    commit/push wrappers, including empty templates and prompt overrides.
+  - `src/shared/source-control-ai-actions.test.ts` covers `fixPushFailure`
+    label, default template, variables, normalization, and action-list inclusion.
+- Remote formatter and store tests:
+  - `src/renderer/src/lib/source-control-remote-error.test.ts` covers push,
+    force-push, publish, and sync push-stage blocked copy plus sync non-push
+    stage negatives, auth/non-fast-forward/protected/pre-receive/submodule
+    regressions.
+  - `src/renderer/src/store/slices/editor.test.ts` covers the `pushBranch` toast
+    path and both sync push-stage and sync non-push-stage toasts.
+- Renderer model and UI tests:
+  - A focused push recovery derivation test covers operation kind, sync
+    push-stage marker, branch mismatch, stale sequence ownership, snapshot file
+    entries, summary, details flag, prompt contents, and ordinary remote errors.
+  - `CommitArea` tests cover the Push blocked notice, Details dialog, AI Fix
+    visible/hidden, ordinary remote errors, no duplicate remote error when a push
+    model exists, and unchanged commit-failure recovery rendering.
+  - Settings tests cover global and repository Source Control AI action rows
+    showing Push failure fixes.
+- Launcher tests:
+  - Generic recovery launcher tests cover commit and push action ids, invalid CLI
+    args before detection, empty template rejection, unavailable saved agent,
+    local versus SSH agent detection, successful launch/focus, and success copy.
+- Checks:
+  - Run targeted vitest files above, `pnpm typecheck`, `pnpm lint`, and
+    `pnpm check:max-lines-ratchet`.
+
+## UI Quality Bar
+
+The Source Control recovery UI must match `docs/STYLEGUIDE.md`: monochrome,
+quiet, dense, token-based, and consistent with adjacent commit-failure recovery.
+Use existing shadcn `Button`, `DropdownMenu`, and `Dialog` primitives, lucide
+icons, `card`/`border`/`destructive`/`muted` tokens, and the existing action
+recipe row patterns. The Push blocked notice should keep the summary readable at
+narrow right-sidebar widths, avoid nested cards, avoid new color values, show
+stable split-button geometry while launching, and keep Details as progressive
+disclosure for long hook output. Dialogs and dropdowns must remain usable in
+light/dark mode and under SSH latency.
+
+## Review Screenshots
+
+1. Source Control after a simulated pre-push hook failure: Push blocked notice
+   with summary, AI Fix, and Details.
+2. Push failure Details dialog showing hook output and Fix with AI.
+3. AI Fix customize-launch dialog for `fixPushFailure`.
+4. Ordinary push auth/protected/remote failure state: regular remote error, no
+   Push blocked notice.
+5. Sync fetch/pull-stage failure state: Sync-shaped remote error, no Push
+   blocked notice.
+6. Source Control AI hidden for the repo: Push blocked notice and Details, no AI
+   Fix.
+7. Source Control AI settings showing the Push failure fixes launch recipe.
+8. Adjacent commit-failure recovery notice still rendering correctly after the
+   shared UI extraction.
+
+## Rollout
+
+1. Tighten shared push-failure classifier/prompt bounds and add the generic
+   recovery command builder.
+2. Make remote formatter/store sync-stage aware and update toast tests.
+3. Add the `SourceControlActionError` snapshot/sequence data and one push
+   recovery derivation helper.
+4. Replace duplicated commit/push launchers with the generic recovery launcher
+   and thin hook wiring.
+5. Extract/reuse source-control recovery UI components, including the existing
+   split-button module.
+6. Verify `fixPushFailure` settings/default/normalizer coverage and i18n labels.
+7. Update targeted tests and run typecheck, lint, and max-lines ratchet.
+8. Validate rendered Electron states with screenshots before opening the PR.
+
+## Lightweight Eng Review
+
+- Scope: Reduced from PR #7787's push-specific parallel path to a shared
+  recovery layer. Keep the feature limited to local pre-push/lint-hook detection,
+  blocked copy, an inline recovery notice, Details, and AI launch. No persistence
+  or provider-specific recovery.
+- Architecture/data flow: Shared code owns classification, prompt text, and
+  command-template rendering; the editor store owns stage-aware toast formatting;
+  `SourceControl` owns transient worktree-scoped failure snapshots and sequence
+  invalidation; the generic launcher owns local/SSH agent discovery and terminal
+  launch.
+- Failure modes covered:
+  - Sync stage ambiguity: only the inner push stage may classify as hook-blocked.
+  - Auth/protected/pre-receive/non-fast-forward/submodule/transport errors stay
+    out of push recovery.
+  - Branch or worktree switches suppress stale recovery models.
+  - Per-worktree sequence tokens prevent older in-flight failures from
+    overwriting newer retries or successes.
+  - Empty custom templates, invalid CLI args, unavailable saved agents, missing
+    worktree context, SSH host detection, and Windows shell planning fail before
+    terminal launch.
+  - Large or hostile hook output and file lists are bounded and treated as data
+    in prompts.
+- Test coverage required:
+  - Shared classifier/prompt/command/action-model tests in `src/shared`.
+  - Remote formatter and editor-store tests for push, force-push, publish, sync
+    push-stage, and sync non-push-stage paths.
+  - Renderer derivation and `CommitArea` tests for Push blocked, Details, AI Fix,
+    hidden AI actions, stale branch/sequence, ordinary remote errors, and
+    existing commit failure recovery.
+  - Generic launcher tests for local/SSH, invalid args, saved-agent unavailable,
+    empty template, and success launch.
+  - Settings tests for global and repo Push failure fixes rows.
+  - Electron validation for all required screenshots; no separate E2E is
+    required if renderer tests cover the model and Electron validates the real UI.
+- Performance/blast radius: No polling, watchers, migrations, or startup work.
+  Runtime cost is one bounded classifier pass over at most 64 KiB, bounded prompt
+  output, and a bounded file snapshot only when a remote action fails. Largest
+  blast radius is the shared recovery UI and launcher used by existing commit
+  failures, so commit recovery needs tests and a screenshot.
+- UI quality bar: Match `docs/STYLEGUIDE.md` and adjacent Source Control density:
+  token-based error state, stable split-button geometry, progressive Details
+  disclosure, no nested cards, concise copy, light/dark compatibility, and
+  visible disabled/loading state under SSH latency.
+- Required review screenshots:
+  1. Push blocked notice after pre-push hook failure.
+  2. Push failure Details dialog with Fix with AI.
+  3. `fixPushFailure` customize-launch dialog.
+  4. Ordinary push auth/protected/remote failure with no Push blocked panel.
+  5. Sync non-push-stage failure with no Push blocked panel.
+  6. Source Control AI hidden: Push blocked without AI Fix.
+  7. Source Control AI settings showing Push failure fixes.
+  8. Existing commit-failure recovery notice after shared UI extraction.
+- Residual risks: Classifier false positives remain possible for unusual local
+  hook-runner output that mentions push context; keep tests biased toward
+  preserving auth, protected-branch, and non-fast-forward behavior. Failure
+  panels are renderer-local, so another Orca window or an external terminal can
+  fix the problem while the old panel remains visible until local retry, remount,
+  or branch/worktree change. Electron validation may need a mocked or temporary
+  repo scenario to trigger a real pre-push hook without mutating user data.

+ * Relocates the terminal daemon's process image out of the app install

+ *
+ * Why: the daemon is forked as plain Node via ELECTRON_RUN_AS_NODE, so its
+ * image is the install-dir Orca.exe and its loaded modules (node-pty native,
+ * ConPTY runtime) map from the install dir. On update, electron-builder's NSIS
+ * installer deletes the old install and force-closes every process whose image
+ * lives under it — killing the daemon and every live terminal it owns. Copying
+ * the daemon's whole file closure to a version-keyed userData dir and forking
+ * from that copy takes its image + loaded modules out of the installer's reach.
+ *
+ * The copy keeps the ELECTRON binary run as node (not stock node.exe): a copy
+ * of Orca.exe (renamed to a distinct image name) is byte-identical, so
+ * run-as-node behavior — no console flashing, asar-correct — matches the in-dir
+ * fork exactly. The win-unpacked layout is mirrored verbatim so
+ * require('node-pty') and node-pty's native loader resolve the relocated tree
+ * identically to the packaged app.
+ *
+ * Fail-open everywhere: any failure returns null and the caller forks the
+ * install-dir host — the pre-relocation behavior, byte-identical off win32.

+ * Single-flight coordinator for fs.listFiles full-tree scans (#7721).

+ * Why: rapid workspace switching used to stack N concurrent full-tree scans
+ * on the single-threaded relay and its one SSH channel, starving small
+ * interactive fs.readDir/fs.stat requests past their 30s timeout. This
+ * coordinator guarantees at most one scan in flight per client:
+ *   - a request for the same root/excludes joins the in-flight scan
+ *     (Quick Open + file-explorer filter share one scan),
+ *   - a request for a different root supersedes it — the old scan is aborted

+ * Regression: SSH typing latency under bulk file-stream load.
+ *
+ * The relay and the client share ONE ordered SSH channel. If the relay
+ * enqueues an entire file's fs.streamChunk frames into the outbound pipe
+ * at once, an interactive pty.data echo emitted mid-stream queues behind
+ * megabytes of bulk data and typing feels seconds-slow.
+ *
+ * These tests model the SSH channel as a congestible in-memory pipe and
+ * assert deterministic byte bounds instead of wall-clock latency:
+ *  - with a saturated sink, the relay stalls the pump on write backpressure
+ *    so at most ~1 chunk frame sits ahead of a pty echo;
+ *  - with a fast sink but an unresponsive client, the fs.streamAck credit
+ *    window bounds the in-flight backlog;
+ *  - legacy clients that never ack still receive the full stream.

-// Lookarounds are intentionally ASYMMETRIC:
-//   - LEFT: reject `[\w./\\-]` so path fragments like `~/codex/ready`,
-//     Windows `C:\codex\ready`, and `codex.ready` cannot mint a strong idle
-//     signal by having the agent name sit earlier in the same path and the
-//     keyword land right after a path separator. Orca is a cross-platform
-//     Electron app, so Windows path separators must be handled too.
-//   - RIGHT: reject only `[\w\-]` so legitimate sentence-style titles like
-//     "Codex done." / "Aider idle." / "OpenCode ready!" still match — path
-//     separators after the keyword are not a false-positive vector in
-//     practice and blocking them would regress trailing-punctuation titles.

-// "reworking" ⊃ "working", "overthinking" ⊃ "thinking", "rerunning" ⊃
-// "running", hyphenated compounds like "is-thinking-cap", AND cwd-path
-// fragments like "~/codex/working" or "C:\codex\working". Uses the same
-// asymmetric lookarounds as STRONG_IDLE_KEYWORDS_RE (path separators blocked
-// on the left only so "Codex working." still matches). A false 'working'

+//     "Codex done." / "Aider idle." / "OpenCode ready!" still match — path
+//     separators after the keyword are not a false-positive vector in

+/**
+ * E2E regression test for the reattach mouse-mode leak fixed alongside #7329.
+ *
+ * Why this suite exists:
+ *   A TUI that armed mouse tracking (?1000/1002/1003 + SGR 1006/1016) and died
+ *   uncleanly never emits the disable sequence. The daemon's private-mode
+ *   tracker keeps the mode and buildRehydrateSequences re-arms it on every
+ *   reattach, but POST_REPLAY_REATTACH_RESET used to clear cursor/focus/kitty
+ *   state and NOT mouse modes. A plain shell in the reattached pane then echoed
+ *   every pointer-motion report (`<35;col;rowM`) as literal text.
+ *
+ * What it covers (full stack, no mocks):
+ *   - First launch arms the leak for real: a fixture writes the enable sequence
+ *     to stdout and exits, and the live pane is asserted to enter mouse-reporting
+ *     mode (the byte flow the daemon's tracker also records and re-arms).
+ *   - After a warm reattach, the renderer terminal ends with mouse reporting
+ *     DISARMED: mouseTrackingMode is 'none', the enable-mouse-events class is
+ *     gone, and real pointer motion produces zero mouse reports.
+ *   - A positive control re-arms the same modes and confirms the motion probe
+ *     does observe reports, so the "zero reports" assertion cannot pass vacuously.
+ *
+ * What it does NOT cover:
+ *   - That the daemon's buildRehydrateSequences re-arms the mode on reattach —
+ *     locked by repro-7329-remote-snapshot-corruption.test.ts against the real
+ *     serializer + xterm. This suite proves the reset half end to end.
+ *   - Live-agent panes keeping mouse via POST_REPLAY_LIVE_AGENT_REATTACH_RESET
+ *     (unit-tested in pty-connection.test.ts).

+/**
+ * Orca main-thread jank / subprocess-churn benchmark (issue #7576).
+ *
+ * Reproduces the reporter's setup: a running app with an active git worktree
+ * and the Source Control sidebar open, measured at steady state. The app is
+ * launched with ORCA_MAIN_THREAD_DIAGNOSTICS=1 so the main process emits one
+ * `[main-thread] {json}` stderr line every 5s containing:
+ *   - worst event-loop stall in the window (maxGapMs) and stall counts
+ *   - subprocess spawns since the last report, keyed by command
+ *     ("git status", "gh api", …) with the synchronous spawn-initiation cost
+ *     that held the main thread (blockMsTotal/blockMsMax)
+ * On macOS the bench also tails the unified log for the exact
+ * "Performance Diagnostics" warnings from the issue and records which process
+ * emitted them, so spawn churn and OS warnings can be correlated by timestamp.
+ *
+ * Usage:
+ *   node tools/benchmarks/main-thread-jank-bench.mjs --label baseline
+ *     [--duration-s 120] [--warmup-s 20] [--fixture-dir <path>]
+ *     [--exe <path-to-packaged-Orca>] [--headless] [--no-log-stream]
+ *
+ * The window must stay VISIBLE during the run: git-status polling is gated on
+ * document visibility, so a hidden/minimized window measures nothing.
+ * --headless exists only for smoke-testing the harness itself.
+ *
+ * Prereq (when not using --exe): `pnpm build:electron-vite` so out/ exists.
+ * Results: tools/benchmarks/results/main-thread-jank-<label>-<timestamp>.json

+# daemon-relocation-spike
+
+A throwaway probe that answers one empirical question for Phase 1 of the
+Windows update-survival work:
+
+> What is the **minimal set of files** that must be copied out of a packaged
+> `win-unpacked` build so that a **copied `Orca.exe`** — run with
+> `ELECTRON_RUN_AS_NODE=1` from a directory **outside** the install dir — can:
+> (a) start the terminal daemon and signal ready over IPC,
+> (b) spawn a real ConPTY `node-pty` session, write input, and read output back,
+> (c) do all of that while holding **no open file handles into the app/install
+> dir**, so an NSIS update could delete the original install.
+
+## Why this matters
+
+The daemon is `fork()`ed from the app's own Electron binary (`Orca.exe`) with
+`ELECTRON_RUN_AS_NODE=1`, from the **install** directory. On a Windows update,
+electron-builder's NSIS installer (a) runs `uninstallOldVersion` (deletes the
+registered install's files) and (b) `CHECK_APP_RUNNING` force-closes every
+process whose image path is under `$INSTDIR`. So the daemon dies and its held
+file locks can break the update.
+
+The Phase 1 fix copies the daemon's whole file closure **out** of the install
+dir (into `%LOCALAPPDATA%`/userData) and forks the daemon from the **copy**, so
+its image + all loaded modules live outside `$INSTDIR`. This spike measures how
+small that copy can be while still working.
+
+We keep the **Electron binary run as node** (not a stock `node.exe`): a prior
+attempt (#7473, reverted) switched to stock node and caused Windows-console
+flashing (stock node lacks Electron's `kHideConsoleWindows`) plus asar breakage.
+This spike does **not** reintroduce stock node.
+
+## Usage
+
+```
+# Real run (Windows, needs a packaged win-unpacked build):
+node tools/daemon-relocation-spike/spike.mjs \
+  --app-dir <path-to-win-unpacked> \
+  --work-dir <scratch-dir> \
+  [--tier full|no-gpu|minimal] \
+  [--keep-work-dir]
+
+# Offline logic validation (any OS, no build, no launch):
+node tools/daemon-relocation-spike/spike.mjs --selftest
+```
+
+Exit code is `0` only when the run **PASSES**: daemon ready, PTY echo
+round-trips the nonce, the daemon's main module is the copied `Orca.exe`, and
+**no** loaded module resolves under `--app-dir`.
+
+## Tiers (defined as data in `tier-file-set.mjs`)
+
+Every tier includes the irreducible core: `Orca.exe`, `icudtl.dat`, both V8
+snapshot blobs (`snapshot_blob.bin`, `v8_context_snapshot.bin`), the daemon
+bundle (`out/main/daemon-entry.js` + `chunks/` + `out/package.json`), and the
+whole `node-pty` package (native `conpty.node` + the sibling `conpty/` runtime
+dir holding `conpty.dll` + `OpenConsole.exe`).
+
+Tiers differ only in which top-level `*.dll` files they carry:
+
+| Tier      | Top-level DLLs                                                    |
+| --------- | ---------------------------------------------------------------- |
+| `full`    | **all** top-level `*.dll`                                         |
+| `no-gpu`  | all **except** GPU/render DLLs (`libEGL`, `libGLESv2`, `vk_swiftshader`, `vulkan-1`, `d3dcompiler_47`); **keeps** `ffmpeg.dll` |
+| `minimal` | **none** (exe + data blobs + daemon bundle + node-pty only)      |
+
+Trimming further is a config change (edit `TIER_DEFINITIONS` / `GPU_DLLS`), not
+a code change.
+
+## How node-pty's native + ConPTY runtime is handled
+
+The whole `node-pty` package tree is copied, and **the entire win-unpacked
+layout is mirrored verbatim** (every copy destination is relative to the
+win-unpacked root, not the asar-unpacked root). This matters because node-pty is
+packaged at `resources/node_modules/node-pty` — a **sibling** of
+`app.asar.unpacked`, not under it (see
+`config/packaged-runtime-node-modules.cjs`). Mirroring the full layout preserves
+two resolutions from the relocated path:
+
+1. **The daemon require-closure** resolves `require('node-pty')` by walking
+   parent dirs up from the mirrored
+   `resources/app.asar.unpacked/out/main/daemon-entry.js`, which passes through
+   `resources/` and finds `resources/node_modules/node-pty` — exactly as in the
+   packaged app.
+2. **node-pty's own native loader** resolves `conpty.node` from `build/Release`
+   (or `prebuilds/win32-<arch>`) relative to node-pty's own `__dirname`, and
+   node-pty's Windows addon loads `conpty.dll` from `<dir-of-conpty.node>/conpty/`
+   and spawns `OpenConsole.exe` from beside it. Copying the tree verbatim keeps
+   all three side-by-side.
+
+### `ORCA_NODE_PTY_NATIVE_DIR`
+
+The reverted #7421 added a `node-pty` patch that reads
+`ORCA_NODE_PTY_NATIVE_DIR` to override the native dir. **The current branch's
+`config/patches/node-pty@1.1.0.patch` does NOT contain that override** — it was
+reverted. The spike therefore relies on **layout preservation** (copying the
+node-pty tree at its default relative path) rather than the env override. The
+spike still *sets* `ORCA_NODE_PTY_NATIVE_DIR` to the relocated native dir so it
+keeps working if pointed at a build that carries the patch, but on this branch
+the var is inert.
+
+**Implication for the real Phase 1 implementation:** if the production copy does
+NOT preserve node-pty at the path its loader resolves by default (e.g. if the
+daemon-entry is relocated without the sibling `node_modules/node-pty`), the impl
+will need to **re-add the `ORCA_NODE_PTY_NATIVE_DIR` patch** from #7421. If it
+mirrors the layout as this spike does, the patch is not strictly required —
+though re-adding it is the more robust choice.
+
+## The handshake / client
+
+`ndjson-client.mjs` is a small standalone NDJSON client (no electron/src
+imports) that mirrors `src/main/daemon/daemon-server.ts`:
+
+1. Read the token the server writes to the token file after it begins listening.
+2. Open a **control** socket, send `hello {role:'control'}`, await
+   `{type:'hello', ok:true}`.
+3. Open a **stream** socket with the **same** `clientId`, send
+   `hello {role:'stream'}`.
+4. `createOrAttach` on control, then `write` `echo SPIKE-OK-<nonce>\r\n`, and
+   read `data` events on the stream socket until the nonce appears **alone at
+   line start** (executed output, distinct from the echoed input line).
+
+`PROTOCOL_VERSION` is read at runtime from `src/main/daemon/types.ts` so the
+client never drifts from the daemon.
+
+## The handle probe
+
+`loaded-modules.ps1` (via `loaded-module-probe.mjs`) runs
+`Get-Process -Id <pid>` and enumerates `.Modules[].FileName`. Any module path
+under `--app-dir` is a **lock risk** (the installer cannot replace a file a live
+process maps), so a passing relocation must show **zero**. It also asserts the
+process's **main module** is the copied `Orca.exe`, not the install-dir one.
+
+Loaded DLLs are the lock-critical set. Data files (`icudtl.dat`, asar) are not
+memory-mapped as modules, so this probe does not enumerate them — the copy plan
+handles those by construction (they are copied, so nothing opens the originals).
+
+## What remains unverified until CI runs it
+
+This session has **no build**, so the launch path is unproven. Verified here:
+`node --check` on every `.mjs`, a green `--selftest`, and clean
+`pnpm exec oxlint`. Open questions the real CI run must answer:
+
+- Whether `TIER_MINIMAL` (no top-level DLLs) boots `Orca.exe` as node at all, or
+  whether run-as-node still needs `ffmpeg.dll` / others — this is the core
+  empirical result.
+- Whether the daemon bundle require-closure needs any **other** unpacked
+  `node_modules` beyond `node-pty` (surfaces as a ready-timeout if so).
+- Whether any loaded module still resolves under `--app-dir` (the handle probe
+  will name it).
+
+## Recommendation for the likely-minimal tier
+
+`no-gpu` is the safe minimal target to ship: run-as-node Electron does not
+initialize the GPU/render stack, so `libEGL` / `libGLESv2` / `vk_swiftshader` /
+`vulkan-1` / `d3dcompiler_47` are very unlikely to load, while `ffmpeg.dll` and
+the ICU/snapshot data are retained because the Electron bootstrap references
+them regardless of run-as-node. Run `--tier minimal` on CI first: if it PASSES,
+ship minimal; if `Orca.exe` fails to boot without the non-GPU DLLs, fall back to
+`no-gpu`. `full` is the always-works upper bound for comparison.

+# Repro harness: watcher.node main-process crash (issue #7547)
+
+Manual, Windows-focused harness for the `@parcel/watcher` native crash class
+(`0xc0000409` fail-fast / `0xc0000005` AV in `watcher.node`; same family as
+macOS #5377 and Linux #6635). Not run in CI — it deliberately crashes
+processes and hammers the filesystem.
+
+All watched/churned directories live under `os.tmpdir()`, never the repo.
+
+## Reproduce the bug (in-process watcher, pre-fix architecture)
+
+```
+node tools/repro-watcher-crash-7547/run.cjs delete-root 3 15000
+```
+
+Spawns `child.cjs`, which uses `@parcel/watcher` **in-process** the way
+`filesystem-watcher.ts` did before the fix. Scenarios (arg 1):
+
+- `delete-root` — subscribe to worktree-like dirs, churn files, delete the
+  watched root mid-churn, unsubscribe (worktree deletion during agent writes).
+  Crashes in seconds on Windows.
+- `unsub-churn` — rapid subscribe/unsubscribe cycles against live churn.
+  Also crashes: the trigger is `unsubscribe()` racing active event delivery
+  (`CancelIo` from the wrong thread leaves a pending `ReadDirectoryChangesW`

+Build first so the forked entry exists, then run from the repo root:
+
+```
+npx electron-vite build
+node tools/repro-watcher-crash-7547/fixed-child.cjs 15000
+```
+
+`fixed-child.cjs` esbuild-bundles the real `src/main/ipc/parcel-watcher-process.ts`
+client and runs the same `delete-root` + `unsub-churn` load through the forked
+`out/main/parcel-watcher-process-entry.js`. Expected output: contained watcher
+process crashes (counted, recovered by respawn+resubscribe, surfaced through
+`onInterruption`), a final health check that sees live events, and exit 0.
+
+Exit codes: 0 pass · 5 watcher not functional at end · 6 in-process fallback
+used (isolation not exercised) · 7 watchdog · 8 premature exit.

+// Throwaway repro harness for issue #7547 — Windows main-process crash in
+// @parcel/watcher (watcher.node, 0xc0000409 fail-fast).
+//
+// Runs ONE scenario in THIS process (the parent runner spawns us in a loop and
+// watches our exit code). Each scenario mimics a real Orca usage pattern:
+//
+//   delete-root  — subscribe to worktree-like dirs, churn files, delete the
+//                  watched root mid-churn (worktree deletion during agent
+//                  writes). Exercises the WindowsBackend error path
+//                  (handleWatcherError -> Watcher::notifyError on the backend
+//                  thread).
+//   unsub-churn  — rapid subscribe/unsubscribe cycles on dirs with live churn
+//                  (worktree switching + 30s-grace teardown compressed).
+//                  Exercises pending-ReadDirectoryChangesW teardown.
+//   worker-mix   — worker_threads subscribe to the SAME dirs as the main env
+//                  (desktop explorer watch + runtime file-watcher worker on one
+//                  worktree). Workers exit cleanly, exit without unsubscribing,
+//                  or are terminate()d — then new workers subscribe again so
+//                  std::thread::id values recycle against the process-global
+//                  shared native Watcher.
+//   overflow     — one watched dir, massive delete/rename bursts with long
+//                  file names to force ERROR_NOTIFY_ENUM_DIR ("Buffer
+//                  overflow") on the backend thread.
+//   mixed        — all of the above concurrently.
+//
+// Exit code 0 = survived the scenario. A native crash surfaces as the child's
+// exit code (0xC0000409 = 3221226505) in the parent.

+# win-update-e2e — packaged NSIS update proof harness
+
+**Windows only.** Given two Orca Windows installers (version N and N+1), this
+harness performs a real silent update and proves, with machine-checkable
+assertions, what happens to the terminal **daemon** and its **sessions** across
+the update — and whether any console/terminal window flashes.
+
+It is the Phase 0 "proof harness" deliverable from
+[`docs/windows-terminal-update-survival-plan.md`](../../docs/windows-terminal-update-survival-plan.md).
+It exists specifically because the July 2026 attempt shipped four broken RCs
+without ever installing the packaged artifact (see
+[`docs/windows-terminal-update-survival-postmortem.md`](../../docs/windows-terminal-update-survival-postmortem.md),
+"Why verification missed every one of these"). Its design refuses to repeat
+those verification failures:
+
+- **Window visibility is measured by window enumeration + owner/canary
+  attribution — never by conhost command-line heuristics.** The post-mortem
+  proved conhost flags invert with parent console state and `MainWindowHandle`
+  is `0` for Windows-Terminal-hosted consoles. See `window-enum.ps1`.
+- **Interactivity is proven by execution, not by result-shape.** Typed commands
+  write sentinel **files**; the harness checks the files. A command that "runs
+  and returns correct output" but flashes a window is still caught, because the
+  window watch runs independently.
+- **The daemon is identified by command-line marker, never by exe name.** With
+  `ELECTRON_RUN_AS_NODE` the daemon image is `Orca.exe`; a relocated Phase 1
+  host may be a differently-named copied binary. See `daemon-processes.mjs`.
+- **Each run uses an isolated userData dir** so its daemon's socket/token path
+  is unique and never collides with the many other daemons a dev box or CI
+  runner can host.
+
+## Usage
+
+```
+pnpm win-update-e2e --from <setup.exe> --to <setup.exe> --expect <profile>
+# or download release assets via gh (one call each):
+pnpm win-update-e2e --from-release v1.4.124-rc.9 --to-release v1.4.125-rc.1 --expect cold-restore
+```
+
+Or directly: `node tools/win-update-e2e/run.mjs --from ... --to ... --expect ...`
+

+| `--keep-install`                              | Skip teardown/uninstall for debugging (ignored in isolated) |
+
+### Profiles
+
+- **`cold-restore`** — **today's** behavior and the baseline that must keep
+  passing against current `main`. The installer's path sweep kills the in-dir
+  daemon, so: old daemon PID is **dead**, a **fresh** daemon exists, scrollback
+  is cold-restored (best-effort), a new terminal is interactive, and **zero**
+  unexpected console/terminal windows appear.
+- **`survival`** — the Phase 1 target. Daemon PID **unchanged** across the
+  update, marker process **still alive**, the pre-update session still
+  interactive (typed input echoes, Ctrl+C interrupts), and **zero** unexpected
+  windows.
+
+## Safety
+
+This harness installs, overwrites, and can uninstall a real app. Two guards
+protect a developer's machine; a clean CI/VM is unaffected by either:
+
+- **Pre-existing app process → hard refusal.** If an Orca _app_ process (not a
+  daemon) is already running, the run aborts and prints the offending PIDs. The
+  harness never kills a process it did not start.
+- **Pre-existing install → refusal unless `--allow-existing-install`.** If an
+  Orca install already exists under `%LOCALAPPDATA%\Programs`, the run refuses,
+  because installing N then N+1 would silently overwrite that build and leave
+  the `--to` version behind. Pass `--allow-existing-install` to proceed anyway.
+
+Uninstall behavior at teardown follows ownership:
+
+- **No pre-existing install** (harness fully owns it): teardown silently
+  uninstalls, unless `--keep-install`.
+- **`--allow-existing-install` was used** (an install existed first): teardown
+  does **not** uninstall — removing a build the harness did not place would be
+  wrong. It prints a prominent note that the machine now has the `--to` version
+  and the prior build was not restored.
+
+## Isolated install mode (developer machines)
+
+On a clean CI/VM the harness installs into the default per-user location
+(`%LOCALAPPDATA%\Programs\Orca`). A developer's box already has a real Orca there,
+and the safety guards above would (correctly) refuse to run. **Isolated mode**
+(`--install-dir <path>`) lets the harness run on that box without disturbing the
+real install.
+
+**The /D mechanism.** electron-builder's NSIS honors the standard NSIS `/D=<path>`
+override for the install *directory* (`node_modules/app-builder-lib/templates/nsis/multiUser.nsh`).
+`/D` is special: it must be the **last** argument and **cannot be quoted**, so the
+path must be absolute and **spaces-free** (validated by `validateInstallDir`). The
+installer's kill-sweep only matches processes under its own `$INSTDIR`, so a
+separate directory never touches the real install's app or daemon processes.
+
+**Why registry/shortcut backup-restore exists.** `/D` relocates *files only*.
+Regardless of `/D`, the installer writes `InstallLocation` + the uninstall entry to
+the **same per-user HKCU keys** as the real install
+(`HKCU\Software\<APP_GUID>` and
+`HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall\<key>`,
+`node_modules/app-builder-lib/templates/nsis/include/installer.nsh`) and rewrites the
+Start Menu / Desktop shortcuts. Left hijacked, the user's **next real update would
+install into the test directory**. So isolated mode, before installing:
+
+1. **Snapshots** the shared state (`registry-shortcut-backup.mjs`): `reg export`s
+   each existing key to `.reg` files, copies the Orca `*.lnk` shortcuts, and records
+   a manifest (which keys/shortcuts existed, the pre-run `InstallLocation`).
+2. Runs the full install → update → assert proof against the isolated directory.
+3. **Always restores** at teardown (a `try/finally` wraps everything after the
+   snapshot): `reg import`s keys that pre-existed, `reg delete`s keys the test
+   created, copies shortcuts back / deletes test-created ones, then **re-reads
+   `InstallLocation` and verifies** it matches the snapshot. On mismatch it prints a
+   loud block with the exact manual `reg import` command to recover. Isolated
+   teardown **always** uninstalls the test install (the harness owns the directory)
+   and removes the directory if empty — `--keep-install` is ignored.
+
+**Residual risk.** The backup/restore covers `InstallLocation`, the uninstall entry,
+and the Orca shortcuts — the state that steers a future update and the user-visible
+launchers. It does **not** attempt to snapshot auto-update state files under the real
+install's `userData` (the harness uses an isolated `userData` throughout, so it never
+writes there), and it cannot restore state if the machine loses power mid-teardown
+(re-run with a valid `--install-dir` to let restore complete, or run the printed
+`reg import` by hand). The `.reg` backups live under the run's temp dir until a
+successful teardown removes it.
+
+**Example.**
+
+```
+pnpm win-update-e2e \
+  --from-release v1.4.124-rc.9 --to-release v1.4.125-rc.1 \
+  --expect cold-restore --install-dir C:\OrcaE2E
+```
+
+Read-only, touches nothing — print what isolated mode would snapshot on this machine:
+
+```
+node tools/win-update-e2e/registry-shortcut-backup.mjs
+```
+
+## What it does
+
+1. **Preflight** — assert win32; warn if elevated; **refuse** to run if a
+   pre-existing Orca _app_ process (not a daemon) is running that the harness
+   did not start (it is printed and the run aborts — the harness never kills a
+   user's processes); snapshot the baseline set of visible top-level windows.
+2. **Install N** silently (`<setup.exe> /S`) and locate `Orca.exe`.
+3. **Launch** the installed app (Playwright `_electron`, isolated userData),
+   create ≥2 terminals, start a **marker** in one: a `powershell` loop that sets
+   a unique window-title **canary**, records its PID, and heartbeats a file.
+4. **Record** the daemon PID (scoped pid-file + live-process scan), marker PID,
+   and session tab ids.
+5. **Close** the app normally; verify the detached daemon is still alive.
+6. **Start the window watch** — a background PowerShell loop polling visible
+   top-level windows every 500ms, diffing against baseline, recording every new
+   window (and title change) to a JSONL log through the update and soak.
+7. **Install N+1** silently (the update).
+8. **Relaunch** the app.
+9. **Assert** per profile, then print a PASS/FAIL/INFO evidence table.
+10. **Teardown** (unless `--keep-install`) — close app, kill only harness-created

+
+```
+# Opens a real transient console window and asserts the watch catches it:
+node tools/win-update-e2e/window-watch.mjs --selftest
+
+# Read-only: list daemon processes + PID files on this machine:
+node tools/win-update-e2e/daemon-processes.mjs [--user-data <dir>] [--scope <substr>]

+# Emit the current visible-window snapshot as JSON:
+powershell -File tools/win-update-e2e/window-enum.ps1

+## Known limitations
+
+- **Scrollback fidelity is best-effort.** A production build renders the
+  terminal with WebGL, so xterm text is not reliably in the DOM and the e2e
+  `SerializeAddon` is not exposed. When text cannot be read the check reports
+  `INFO` (unknown), never a false `FAIL`.
+- **Daemon file log** does not exist yet in packaged builds (the fork's stdio is
+  suppressed). The "daemon log free of ERROR lines" assertion is `INFO` until
+  Phase 0 daemon logging lands, then it reads `<userData>/logs/daemon.log`.
+- The harness assumes the packaged main honors `ORCA_E2E_USER_DATA_DIR` to
+  relocate userData; verify this against a real packaged build.

+                           leaving a developer's REAL Orca install untouched.
+                           The path must be absolute and contain NO SPACES (the
+                           NSIS /D override cannot be quoted), must not be the
+                           default install location, and must not point at a
+                           non-empty directory that is not a prior harness
+                           install. Isolated mode snapshots and restores the
+                           shared per-user registry keys + shortcuts at teardown
+                           so the real install's "next update" target is
+                           preserved. See README "Isolated install mode".
+  --allow-existing-install Proceed even if an Orca install already exists. The
+                           run overwrites it with the --from/--to versions and
+                           leaves the --to version installed (your prior build
+                           is NOT restored). Without this flag the harness
+                           refuses to run when an install exists, to protect a
+                           developer's real Orca. Clean machines (CI/VM) never
+                           need it. Ignored in --install-dir mode, which never
+                           touches the real install.

+  window-enum.ps1 — enumerate visible top-level windows with owner attribution.
+
+  Dot-source this file, then call Get-VisibleTopLevelWindows. It returns objects
+  { handle, pid, processName, title } for every visible, non-cloaked top-level
+  window that has a title.
+
+  WHY window enumeration (and never conhost command-line heuristics): the July
+  2026 post-mortem proved that (a) conhost flag interpretation inverts depending
+  on the parent's console state, and (b) MainWindowHandle is 0 for
+  Windows-Terminal-hosted consoles, so handle-based "is it visible" checks read
+  a visibly-flashing window as hidden. The only sound signal is a real visible
+  top-level window, attributed to an owner process and (for our own children) a
+  canary title. This function is the single instrument every probe shares.
+#>

+  window-watch.ps1 — poll visible top-level windows and record every NEW one.
+
+  Runs a tight loop (default 500ms) that diffs the current visible top-level
+  windows against a baseline snapshot, appending any window handle it has not
+  seen before to a JSONL file as one event per line:
+    { "ts": "<iso>", "handle": <n>, "pid": <n>, "processName": "...", "title": "..." }
+
+  It stops when -DurationSec elapses or -StopFile appears (whichever comes
+  first), so the orchestrator can end the watch deterministically after the
+  post-relaunch soak window.
+
+  Attribution is by owner process + title only (see window-enum.ps1 for why
+  conhost heuristics are invalid). Classification of which new windows count as
+  "unexpected" (canary title, terminal/console owner) is done by the JS
+  assertions layer against this raw event log — this probe records everything.
