Brennan Benson c0e2b73395 feat(native-chat): require Codex 0.136.0 for chats (#26684)
* Require Codex 0.136.0 for native chats

* Add host-owned Codex install and update actions

* Bind Codex checks and maintenance to the selected installation

* Resolve Windows updater cleanup through system helpers

* Use one child environment for Codex checks and launch

* Expire Codex readiness and reconcile current host jobs

* Resolve Codex checks against the child command search path

* Restrict global npm repair to the selected Codex install layout

* Pin the host updater directory through Windows supervision

* Synchronize Codex maintenance fixtures on readiness

* Unify Codex notices and recover version-refused chats

* Route Codex recovery to the operation that remains

* Preserve Codex setup execution errors in the job log

* Preserve UTF-8 in Codex setup logs

* Remove unused Codex host installation detector

* Require host administration for Codex maintenance

* Show a missing Codex explanation once

* test(native-chat): give scripted Codex runtimes their installation fact; keep the registry out of the relay

Runtime tests that drive a scripted Codex app-server still ran the new
version check against whatever codex was on the machine's PATH: refused
on CI (no codex), and on a dev machine it ran the real codex --version.
A scripted transport now must state the Codex it stands for
(readCodexInstallation), asserted at install, and the tests get it from
one scriptedCodexTransport fixture.

The relay's Codex maintenance path reached @orca/windows-registry through
resolvePathEnvKey's re-export in windows-environment-path; import it from
its registry-free module instead.

Also update the catalog-probe test for the shared child environment.

* refactor(native-chat): drop the Update Codex action; keep Install for a missing Codex

A too-old Codex now gets only the plain message ("Codex X is too old for
chats. Update to 0.136.0 or newer.") with no button and no job. The
existing rechecks (window focus, the <=30 s expiry of a saved result)
retry the refused chat once the user has updated Codex themselves.

A missing Codex keeps the Install Codex button: `npm install -g
@openai/codex` with the npm on the chat's PATH, as a host-run job with
its log, then a recheck and recovery. A configured Command that is
missing gets the message only, since a global npm install would not
land at that path.

Removed: the `codex update` command and its 0.126 floor, manual
instructions, npm layout and launcher identity detection, the action
descriptor (install|update) and its titles, the legacy capability, and
the SSH relay maintenance path (structured chat never runs over SSH or
WSL), so the relay preflight handler is back to main's.

* refactor(native-chat): keep Install Codex in Settings only

When Codex isn't installed, main already hides Codex from the New tab menu,
so the in-chat Install button was almost never reachable. Settings → Agents
already shows "Codex isn't installed." with Install Codex.

- Chats and the new-workspace composer now only state "Codex isn't
  installed." (no button, no install job from the chat).
- The Install action, its busy spinner and the host-busy subscription move
  into the Settings Codex row, the only place that starts the job.
- The store no longer re-checks every other workspace context when a job
  finishes. A refused chat recovers through the same re-check a too-old
  Codex uses (window focus, or the <=30 s expiry of a saved result).
- The chat recovery key no longer includes the install job id.
- Tests: Settings drives the install; a new test proves a chat refused for
  a missing Codex recovers through focus after a Settings install, not
  through the job; the expiry recovery test covers missing and too old.

* refactor(codex): check chat compatibility when acquiring the child

* Restore workspace submit guard and simplify Codex maintenance

* Keep only the Codex chat minimum version

Jinwoo Hong 8b2a5e45f1 Re-land Claude per-account folders (#24434, #26405) with the upgrade and proxy fixes (#26801)
* Revert "Revert Claude per-account folders (#24434, #26405) before release (#26638)"

This reverts commit 9ca9b4e36b.

* Move the terminal daemon protocol to 44 for the re-landed claude function

v43 daemons (the revert) lack the claude account function, so new terminals must not reuse them. v42 and v43 stay attachable.

* Move the local build compatibility contract to daemon protocol 44

* Point the old-terminal test at daemon protocol 44

* Claude accounts re-land: never sign anyone out, keep proxies working, accounts mirror ~/.claude (#26769)

* Run a Claude account on System default until it has its own login

An account saved before per-account folders has no login in its folder. While System default (~/.claude, or the user's own CLAUDE_CONFIG_DIR) is signed in to the same email, the router sends every launch there and writes that choice into the pointer file, so nobody is logged out by the update. Once the account signs in to its own folder, the next launch uses it. The WSL router follows the same rule with the guest's ~/.claude.

* Refresh each Claude account folder from ~/.claude before every launch

~/.claude (or the user's own CLAUDE_CONFIG_DIR) is now the master copy. Each account folder gets its whole settings.json, including the proxy address and its key, and every .claude.json key except the login, Claude's account caches and install ids, so first-run questions are not asked again. Every other top-level entry is linked (folders) or copied (files), except Claude's per-folder daemon, jobs, live sessions, login files and throwaways. sessions is no longer shared, and an earlier link is undone.

The refresh runs before every Claude Orca starts, for each new terminal and on account switch. Orca never writes back to ~/.claude. The ledger that tracked selective sharing is gone.

* Route chat auth and unselected-account usage through the Claude router

Chats decided whether to drop inherited Anthropic auth from the selection alone, so an account running on System default lost the user's own key. They now ask the router, as terminals, AI commit messages, automations and usage already do. Usage for an unselected account is read where its launches would run. A test reads every entry point through the fallback and fails if a launch path outside the router reads the Claude selection or builds an account folder. The router's two launch errors move to their own file to keep it under the line limit.

* Show Claude account sign-in prompts only when an account cannot run

With the fallback, an account System default is signed in to already works, so:
- The one-time "Finish setting up your Claude accounts" toast is gone.
- Accounts System default covers no longer need a sign-in: no Sign in in the status bar menu or Settings, and they can be selected.
- The old-terminal banner shows only when claude in that terminal would run a different account than the selected one, and asks again after a switch. Its wording is unchanged.

The retired toast's saved flag stays in the paired-client schema so an older client's write is still accepted. The email comparison moves beside the login reader to keep the router under the line limit.

* Keep the user's shell Anthropic auth on Claude account launches

A signed-in account's launches used to drop ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN and CLAUDE_CODE_OAUTH_TOKEN from the inherited environment while ANTHROPIC_BASE_URL passed through, so a proxy set in the shell got the subscription login and answered 401. Host launches on an account now keep the shell's auth with its address, as System default does. Chats still name the account kind in a failed sign-in, now from the router rather than from whether auth was dropped.

* Share from ~/.claude only what Claude itself would seed into a new folder

The deny list missed much of Claude's runtime state, so tokens, locks and live files such as .session_ingress_token, server-sessions.json and remote-control were copied or linked over each account's own every launch. The list now mirrors the one Claude uses when it seeds a fresh config folder from ~/.claude: its runtime entries, every hidden entry, daemon files and agent memory. teams, ide, downloads and scratch are on it, so they stay per folder.

* Merge trusted folders and MCP servers into an account instead of replacing them

Each refresh replaced the account's projects and mcpServers with ~/.claude's, so folder trust and allowed tools recorded only in the account were lost, and a refresh landing between Orca's folder-trust write and Claude's start brought the trust dialog back. Both are now merged per folder path or server name: ~/.claude wins for entries it has, the account keeps the rest, and a folder trusted in the account stays trusted. Both writers take Claude's lock on the file, so the order no longer matters.

* Require the same organization before System default stands in for an account

The fallback compared emails only, so one email saved for two organizations made both accounts run on whichever organization System default was signed in to. When the saved account and System default's login both name an organization, it must now match too, on the host and in WSL, and the old-terminal banner uses the same comparison. The saved-account lookup the three checks repeated is now one helper.

* Treat v42 terminals as having the claude account function

v42 daemons shipped the same claude function and pointer path as v44, so claude in those terminals already follows the selected account. The old-terminal banner now shows only for daemons before v42 and for v43, the revert, which dropped the function.

* Fail the routing test when a new module resolves the claude binary

The census only caught code that read the Claude selection, not a new launcher that runs claude without asking the router. A second check now lists every module that resolves the claude binary or loads the Agent SDK, each with why it is routed, and fails on any new one, or on a listed one that no longer matches.

* Skip the account refresh on launches that run on System default

A launch that falls back to System default never uses the account folder, so starting a setup for it on every launch was wasted work. Account switches still set the folder up for a later sign-in.

* Give a terminal opened before the login shell's env only the account pointer

At startup, a pane could be routed before the login shell reported the user's own CLAUDE_CONFIG_DIR, so the fallback compared against ~/.claude.json instead. Until that env arrives a pane gets only the pointer, and the pointer is rewritten once it does, so claude typed there reads the right folder. The recent claude --version answer moves beside the version probe to keep the router under the line limit.

* Drop the chat-only Anthropic auth stripping and override refusal

Chats no longer drop the shell's Anthropic auth on any account, so the chat launch's override refusal and the policy's stripAuthEnv could only be reached from test fixtures. The structured auth policy is now just which login a failed sign-in names. Terminals keep their refusal, which still guards WSL launches; the failure reason stays in the shared vocabulary for older peers.

* Publish a new account state file whole

The first .claude.json write went straight to the target, so a crash mid-write could leave Claude a truncated state file. It is now written to a staged file and linked into place without replacing one Claude created meanwhile.

* Read an unselected WSL account's usage where the WSL router would run it

Usage for an unselected WSL account read its saved folder directly, so an account the guest's ~/.claude covers showed no usage, and the read bypassed the router. It now asks the WSL router, after the same check that the distro is already running.

* Keep the shell's Anthropic auth when the claude function runs an account

The claude shell function (POSIX, fish and PowerShell) unset ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN, CLAUDE_CODE_OAUTH_TOKEN, AWS_BEARER_TOKEN_BEDROCK and auth-like ANTHROPIC_CUSTOM_HEADERS before running Claude in an account folder, so a proxy set in the shell lost its key while keeping its address. It now only sets CLAUDE_CONFIG_DIR and Orca's marker, as on System default. Protocol 44 is unreleased, so no new bump; the shell-wrapper snapshots are regenerated.

* Never drop the user's Anthropic auth from a Claude launch

Orca's launches stripped ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN, CLAUDE_CODE_OAUTH_TOKEN, AWS_BEARER_TOKEN_BEDROCK and auth-like ANTHROPIC_CUSTOM_HEADERS for WSL terminals, terminal splits and through the preparation's stripAuthEnv flag, and refused a launch whose agent env set them. If the user's shell overrides the login, that is their setup: every launch now keeps it, on accounts, System default and WSL alike. The flag, the strip paths and the override refusal are gone; the refusal's reason stays in the shared vocabulary so older peers still decode it.

Orca's own process env and the claude --version probe still drop these variables: they are Orca's, not the user's launch.

* Leave out of an account's state everything Claude resets when it signs out

The .claude.json copy left out the login and keys matching cache patterns, but still carried account state such as additionalModelOptionsAnsweredAt, artifactRosterDenied, lastSeenOrgDefaultUpdatedAt and the subscription notices. The copy now leaves out the exact keys Claude resets on logout, beside the install ids, Console API key and first-token date; the cache patterns stay for account caches logout does not reset. Onboarding is still copied.

* Judge an old terminal's Claude banner by the pane's own runtime

The banner compared every old pane with the host selection and showed whenever only a WSL account was selected, so old host panes showed it with nothing to say and old WSL panes were judged by the host's account. The pane now names its runtime: a host pane is compared with the host selection, a WSL pane with its distro's selection through the WSL router, and a pane whose runtime is unknown, or with no account selected for it, stays hidden.

* Leave an account's settings file alone when only Orca's hooks differ from the default home's

* Reread a WSL account's Claude state only when the file changes

* Move tests merged from main onto the account-only Claude auth policy

Brennan Benson e817b0e237 refactor(native-chat): keep the provider resume handle opaque to shared code (#24991)
* refactor(native-chat): keep the provider resume handle opaque to shared code

Shared structured-chat code parsed each provider's resume handle: Claude's
session id and branch leaf, Codex's thread id, through a 'claude' | 'codex'
union every new agent had to widen. The in-memory handle is now
{ transport, agent, nativeId, providerData? }: shared readers use nativeId,
lease and handle-chain checks compare transport and agent, and only the
Claude adapter reads its leaf (providerData).

Stored and wire forms are unchanged for Claude and Codex. One encoding
module writes their typed shapes and decodes both those and the neutral
shape a new transport uses, which an older build refuses as unreadable
rather than reading as Codex. Key and root strings, which fork seeds,
superseded creations and resume offers persist, stay byte-identical.

The journal's own handle type becomes the journal-row and attach-wire
encoding of the same handle, and the journal identity carries the
neutral handle (null before the provider proves one).

No user-visible change.

* fix(native-chat): derive journal-row provider handles from the journal identity

The journal row converter now takes the identity every caller already holds,
so a row's handle has one obvious constructor. Tests that wrote the in-memory
handle straight into journal rows now build it through that converter, and the
processless Claude fixture names a not-yet-proved handle as null.

* fix(native-chat): refuse a stored provider handle written in both forms

A typed Claude or Codex handle that also carries the neutral form's
transport, agent, native id or provider data named two identities; it
was read as Claude or Codex and the next write dropped the other one.
Such a row now stays unreadable and is set aside untouched.

* test(native-chat): use opaque handle in queued rejection fixture

* test(native-chat): share one Codex journal identity in the integration suite

Main grew the suite to the 800-line limit; the opaque-handle import pushed it
over. The two tests built the same identity inline.

* refactor(agent-session): name the handle's adapter state resumeCursor

Rename the neutral provider handle's providerData to resumeCursor before any
row persists the neutral form: it is an adapter-owned resume position (Claude's
transcript leaf), never identity. Claude/Codex stored and wire bytes are
unchanged; their typed shapes never carried the field.

State the stored-form contract (a handle's field set is closed; later per-link
data goes on the chain link, which every build preserves) and pin it with a
record round-trip test. Document that transport records the id space the
native id was minted in, which can differ from the agent's current transport.

Brennan Benson c6cfcc034e refactor(native-chat): structured chat failures always reach the diagnostics log (#24312)
* refactor(native-chat): give the structured chat host one required logger

The structured chat runtime took an optional onError callback that the
desktop never passed, so a late dispatch settlement, an unanswered-dispatch
release, a journal event-sink write and a provider lifecycle delivery that
failed were dropped with no trace. Other host failures went to scattered
console.warn calls, which reach nothing in a packaged desktop build.

The runtime and host now take one required logger (warn/error with a scope
and fields). The production logger writes each entry as a failed span to
<userData>/logs/main.trace.ndjson, which the diagnostic bundle collects, and
to the console (stderr under a supervised headless host). The runtime and the
host wrap it so a logger that throws never fails what it reports, and the
install refuses without one. Sites that deliberately kept a recovery-capsule
error out of the log still log no error object.

* refactor(native-chat): hand the chat host's collaborators the logger, and give orcad its trace file

The delivery loop, idle sweep, queued-message drain, lease renewer, event
sink, conversation map and provider start/exit settlement each took an
internal error callback that the host mapped onto the logger. They now take
the logger itself and log under their own scope. The event sink keeps one
onFailed hook, which decides whether to stop the provider, not whether to
report. The dead-generation settlement returns its failure so each caller
logs it under its own scope.

orcad now installs the desktop's local trace sink under its own data root, so
a headless host's chat failures reach <data-root>/logs/main.trace.ndjson as
well as stderr.

Also passes the logger in the test fixtures the first commit missed, which
tc:node caught.

* fix(native-chat): keep repeated chat failures from flooding the trace file, and record their causes

- The production structured-chat logger writes a repeated failure (same level, scope, session,
  message and error text) once per 5 minutes, carrying how many repeats it swallowed; the
  tracked set is capped at 256.
- Trace entries now carry the error's code (and SQLite errcode) and up to three causes by name and
  message.
- A chat read whose conversation will not open is logged through the host's logger
  (open-for-read), and so are the runtime's chat-tab bookkeeping failures that already hold the
  host.
- orcad writes its own orcad.trace.ndjson, closes it after every quit handler, and flushes it on
  process exit; a trace file that cannot be opened leaves tracing off instead of stopping the app
  or orcad.
- Tests: the desktop wiring test proves the logger reaches the trace sink, and the privacy tests
  read every level the logger received.

* fix(native-chat): log a created chat's tab-publication and launch-prompt failures through the host's logger

* fix(native-chat): key a repeated chat failure on everything its entry writes

The repeat suppression keyed on the message and the error's text, so two refusals with the same
code but different causes, a plain error and a refusal of one code, or two object-valued errors
shared a key and the second was swallowed for five minutes. The key is now the entry's whole
written content (fields, code, errcode, refusal reason, cause chain, a stable rendering of a
non-error value) plus the error's name and message; a refusal's reason is also written.

* test(native-chat): pin that an error's name keeps two repeated failures apart

* test(native-chat): build the refusal in the repeat-key test as the wire does

* fix(native-chat): read an error's code and a refusal's reason by narrowing, not Reflect.get

Brennan BensonandClaude 7a24d3d335 fix(native-chat): the conversation outlives its agent (#22835)
* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

Co-Authored-By: Claude <noreply@anthropic.com>

* docs(native-chat): stop citing the removed handoff in lifecycle comments

Six comments still named the handoff coordinator, a handoff suspend, or a
terminal-owned session as live participants in the flows they describe.

* test(native-chat): type the stalled snapshot drain without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* test(native-chat): pin that a start dead before proving owes no settlement

The removed restart handoff test pinned this branch; nothing else did.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* fix(native-chat): the conversation outlives its agent

Opening a chat no longer starts its agent. A conversation is reached through one host
accessor that opens its journal at rest, and a send is what starts the agent, through
the delivery loop. One idle sweep, every five minutes, stops an agent that has been
quiet for thirty minutes and owes no work, then drops an open journal handle that is
only a cache. Its record, tab, status row and readers stay.

- hold and release are no-ops; hold still builds the host for shipped mobile builds.
- The holders, the holds, the release clock and the exit respawn are deleted.
- Options, the model list, the goal and the context meter answer at rest; a model pick
  at rest is recorded as intent for the next start.
- Compact, rewind, clear and goal changes start the agent first. A send does too when
  a rewind is still in doubt after the conversation opens.
- Orchestration routes mail and group addresses on ownership (the record plus the chat
  tab), not on whether the process runs. An open dispatch keeps its worker running.
- The restart continuation is a send; Resume all holds each slot until the message is
  handed over or rejected.
- A read error never replaces a loaded transcript, and shows the host's own words.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* fix(native-chat): a restart offer ends when the chat's agent starts again

The offer used to end only when the chat's newest user message changed,
because opening a chat started its agent and that start could not be told
apart from real activity. Opening a chat starts nothing now, so the host
reads the fact it already publishes: a chat's status row goes from not
host-owned to host-owned exactly when its agent is started. At that edge the
offer and any failure record for the chat are withdrawn, unless the start is
a resume action's own (its continuation is the oldest undelivered message).

A continuation and a message racing to be first are decided at acceptance:
the continuation is refused, quietly and with nothing filed, when any other
message was accepted since the restart. A failed continuation start leaves
the offer retryable, and each resume action sends its own message id.

Deleted: the newest-user-message comparison, its journal reader, the
continuation filter, and the failure ledger's own "answered by the chat"
check. The marker still carries its message id for one release, so the
previous build can read it.

* fix(runtime): end a transcript stream when its client unsubscribes

Desktop: the IPC subscription controller was dropped as soon as the streaming
handler returned, which for most streams is right after it binds. A later
runtime:unsubscribe then found nothing to abort, so the host kept the subscriber
and derived and sent every publish to a channel no one listened to. The controller
now lives until the renderer unsubscribes, resubscribes the same id, or goes away.

Mobile: disposing an agentSession.subscribe stream now sends agentSession.unsubscribe
with the stream's frame id, so the host ends that subscriber and leaves a sibling
stream on the same socket running. The direct path now passes the frame id the relay
path already passed.

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): one fact ends a restart offer: the chat moved on since the restart

The offer is live while no other message has been accepted in the chat since the
restart and its agent has not proved a start since. The offer list, the resume's
reservation check and the continuation's acceptance check all read that one fact,
so a message whose start then failed withdraws the offer too, and a stale click
finds nothing to act on.

The fact is read off the conversation's open handle, which the restart closed, so
it is retired durably whenever it may have changed: a message accepted, a start
proven. A close and reopen within the same run therefore cannot bring the offer
back. A continuation rejected before it reached the agent does not count, so a
retry after a failed start still runs.

Deleted: the quit-time gate on withdrawal, which changed nothing because the
withdrawal and the quit's own offer write share one queue; the per-action
"withdrawn" flag and the separate acceptance check it paired with.

* test(native-chat): an older build reads the restart offer this build records

The offer lives in a file the previous release reads after a downgrade. Pin that
against the pinned release's own capsule, and run the lane when the marker or the
capsule changes.

* fix(native-chat): read a restart offer against where the journal stood when it was taken

"Since the restart" was read off the conversation's open handle, which the idle
sweep closes: after a reopen, a message the user had already sent looked older
than the handle and the withdrawn offer came back.

The offer now records the journal position (epoch and sequence) at the moment
it is taken, and a message accepted after that position, or a journal on another
epoch, means the chat moved on. That is derived from the journal, so it holds
across any number of closes and reopens. An older build's offer has no position;
only a start withdraws it. Because the message half is now durable, the offer is
no longer rewritten in the recovery file on every accepted message; a proven
start still writes it, since only the host that saw the start knows of it.

* test(native-chat): wait for the listing's retire write before reading the recovery file

* fix(native-chat): keep the terminal-backed chat's read error over its local echoes

Messages winning over a read error is right for the structured chat, whose read retries and whose
messages came from the transcript. The terminal-backed view assembles its list from local echoes
too (a launch prompt, a pending send), so a failed read there showed only those bubbles and no
error. Only the structured pane now keeps messages over an error.

* fix(native-chat): a start retries the exit settlement a failed journal write left owed

An agent exit whose journal settlement write failed releases the lease latched until a retry lands.
Reopening the chat used to be that retry; with reveal now only opening the journal, nothing retried
it before the next app launch, and every send was refused. The start the send needs now runs the
retry first, where the attach would.

* perf(native-chat): answer the owner check without opening the chat

Worktree activation calls agentSession.handoffStatus for every chat tab in the worktree, and the
answer comes from the session record alone. Reaching it through the accessor opened each resting
chat's journal (a full read, the crash-boundary write and a restored status publish), then kept it
open for the idle window. It now checks the record and the adapter's support, as before this series,
and opens nothing.

* fix(native-chat): a read waiting on the session lock opens nothing once quit began

The accessor checked for quit before queueing the open, so a read queued behind a session task ran
its open after teardown had begun and indexed a journal no teardown step would close. The check now
runs at the open itself.

* fix(native-chat): read a failed resume's chat before calling it retryable

Whether a failed resume is retryable is the offer's own rule: the chat has not moved on since the
restart, read from its journal. The failure list read it only for a chat already open, so once the
idle sweep closed a chat the user had moved on in, its failure showed Retry again, and the click did
nothing. The list now opens the failed chats first, as the offer list does.

* test(native-chat): type the provider event sink the settlement test reaches for

* fix(native-chat): say the structured read keeps trying only where it does

The structured pane's "Orca keeps trying to load it" line never showed: the view state filled in an
untranslated fallback whenever the read error had no text, and the empty state prefers any message.
The view state now leaves the message out, so the structured pane shows that line and the
terminal-backed pane its own translated one. Mobile's structured lane does not resubscribe after an
error frame, so it no longer makes the claim.

* test(native-chat): await the send's settlement instead of polling for the start

The at-rest send tests polled for the provider start with vi.waitFor's one-second default, which a
loaded machine outran. They now await the host's own settlement of the message.

* fix(native-chat): a restart offer resumes any time after the quit, and knows its own continuations

The continuation's message id was dated by the quit, and the ledger refuses a new id dated more than
a day back, so Resume or Retry a day after quitting was always refused (on main too). It is now
dated by the resume action.

Telling a rejected continuation from the user's own message read the operation ledger, whose rows
expire after about a day; after that a failed resume stopped being retryable. The offer now
records the continuation each action sends on its own capsule entry, bounded to the newest 16, so
the ids end with the offer. The ledger read is deleted.

* fix(orchestration): route no mail to a structured worker its orchestration released

A structured worker is routed on ownership, and a resting worker's lease is released, so ownership
held while its chat tab stayed listed. A worker the coordinator abandoned and then released, found
at rest by the release, therefore still took peer mail and @worktree: broadcasts, and each one
restarted its agent. Routing now also reads the orchestration's own resource row: once it is
released, direct mail, group addressing and worker-show's addressable answer drop the worker, as
they would a terminal worker whose terminal closed. The chat tab stays, and nothing new is stored.

* fix(native-chat): a failed retry names the user's prompt, not Orca's continuation

A resume's continuation is written to the chat before its start, so after a failed attempt the chat's
newest user message is that rejected continuation. A second failure then showed Orca's own restart
text as the chat's prompt. A retry now keeps the prompt its first failure named.

* fix(orchestration): read the released row optionally, as the authority does

worker-show's observation called the row lookup directly, which a runtime double without it threw on
and failed the structured tab-retirement release.

* fix(native-chat): the status bar drops a restart offer the chat moved on from

The renderer re-read the host's restart offer only when a failed chat showed activity, so after a
message withdrew a pending offer the host answered no chats while the status bar kept counting one,
and clicking it opened nothing. The same watch now covers pending offers: a status change in an
offered chat asks the host again, once.

* test(native-chat): a roster of idle or finished children does not keep an agent awake

The sweep reads owed background work through the shared child-work liveness that upstream's
release clock adopted; a child that went idle or finished is not work the agent still owes.

* fix(orchestration): a task dispatched into a resting structured worker keeps it running

The sweep's open-dispatch check read only the worker-start dispatch that owns the worker's terminal
resource, so a task later dispatched to the same worker (orchestration dispatch --to, which writes a
dispatch with no worker row) did not count: after thirty quiet minutes the worker was stopped while
that task was open, and its coordinator read exited. Any unsettled dispatch addressed to the worker's
process incarnation now counts, derived from the existing rows.

* docs(native-chat): comments stop describing the hold this PR removed

Eight comments still justified orderings and teardown choices by a viewer or dispatch hold that
pinned the provider child. Nothing holds any more; the orderings stand for the binding's redrive
subscription and parked mail, and a chat's agent runs from a send until the idle sweep rests it.
Comment-only.

* fix(native-chat): a restart offer keeps the start its own continuation made

Whose start ended an offer was decided at read time, from whether the offer's continuation was
still the queued message. Once the provider refused that continuation, the child it had started
read as someone else's start, so the offer ended and its failure showed no Retry. The delivery
loop now records which queued message a start is for on the in-memory child, and the child's end
carries it; the offer counts a start as its own when that message is one of its continuations.

* fix(native-chat): an agent gets a full idle window after its owed work ends

The sweep measured quiet only from the last journal row, so once a subagent, command, monitor or
dispatch that had outlived the window ended, the agent was stopped at the next tick. A child can
read done before the lead's wake-up turn writes anything, and stopping in that gap loses the
wake-up. The sweep now counts owed work it observes as activity, which gives the agent the full
window afterwards, as the release clock it replaced did.

* test(claude): the options-read fixture runs a live child

The fixture marked its conversation running with a hasProviderChild field the
session type does not have, so the read took the at-rest path and refused a
session with no record. It now carries a child, which is what the read checks.

* test(native-chat): host tests reach its collaborators through a typed seam

The rest-test rig and three test files read the host's private members with
Reflect.get and cast the result. The host now exposes one test-only accessor,
collaboratorsForTests(), and the subscribers class a subscriberCountForTests()
beside its existing retainedActivityCountForTests(), so the tests are checked
against the real types and the casts are gone.

* refactor(orchestration): one owner answers a structured worker's custody

Routing, group addressing, worker-show and the idle sweep each composed their own reading of
whether orchestration still holds a structured worker, so each new obligation or retirement state
had to be added to every reader. structured-worker-custody now derives both answers from the
worker-terminal list state coordinators see in worker-list: addressable is owned and not released,
and owed work is an active custody or an unsettled task dispatched to the same incarnation. The
owner's state is read through the remote dispatch attachment too, as the terminal transfer lookup
already does. Behaviour is unchanged; a settled worker awaiting its coordinator still rests.

* refactor(orchestration): owed work is an open dispatch on the worker's incarnation

A supervised worker's own dispatch context stays open exactly while the worker is active, so the
separate active-custody branch only repeated it. Owed work is now one fact, which also states the
policy that a worker awaiting its coordinator's decision may rest, and both custody decisions are
written once at the top of the module.

* fix(native-chat): a restart offer knows its continuations by a tag in their id

The offer recorded each continuation id in a list on its capsule entry, capped at 16, and a running
action's id in memory. Both could disagree with the journal: past the cap an old rejected
continuation read as the chat moving on, and a crash during a retry restored the failure's older
entry, which lacked the retry's id. Each continuation id now carries a tag derived from the offer
(its teardown and chat), then the action's own part, so any continuation of this offer, queued or
rejected, is recognised from the journal row and the marker alone. The persisted list, its cap and
the in-memory action map are deleted; the agent-start withdrawal keeps an offer whose own
continuation the start was for, read against the stored marker.

* test(runtime): the legacy-worker reveal test judges its stale snapshot inside the wait

The tui-idle probe reads through readTerminal, which now awaits the structured
worker check before the PTY read, so the probe's snapshot request starts a
microtask later. vi.waitFor missed it on its first check and polled again at
50 ms, the same moment the wait's own 50 ms timeout fired. The stale snapshot
then resolved after the wait had already timed out, so the test passed without
judging it, and the rejection landed before any handler was attached. Vitest
reported that as an unhandled error and failed the shard.

Polling every 1 ms sees the request within a few ms, so the snapshot is judged
while the wait is still pending.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* fix(native-chat): the idle sweep reads owed work every tick

Owed work counted as activity, but the sweep read it only once the idle window had elapsed, so it
refreshed the clock at most once a window. Work that ended just before the next read left the
agent to be stopped at that read, moments after the work ended, which is the gap the refresh was
meant to cover. The sweep now reads owed work on every tick for a started agent, so the window
always runs from the last tick that saw work owed.

* fix(native-chat): a continuation handed to the agent stays sent

The offer read its own continuation as not reaching the agent while its dispatch was pending, which
also covered one already handed over and still unanswered. When the wait for that answer ended first,
the failure it filed read as retryable, and a retry sent a second continuation to an agent that may
have acted on the first. Only a continuation still queued, or rejected, is now read as unsent.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): the interrupted create's own retry continues again

The merge of main's lease-latch fix replaced that test's retry of the interrupted create, under its
own operation id, with a fresh start whose result nothing read. That fresh start passes with the
released-reservation continuation deleted, so the case the fix exists for went untested. The retry
and its assertion are main's again.

* docs(native-chat): three comments that still had views starting agents

A start with nothing queued now comes from a command, goal change or rewind; an interrupted compaction
left alone would refuse every send, so no agent would ever start to finish it; and a current host
raises the unattached read refusal only once quit began, with the attach window belonging to an older
host.

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* test(native-chat): a reader's open settles the turn a failed exit settlement left running

An exit whose settlement write failed leaves its turn running in the open journal. PR 1's open now
settles it, and this pins the two reads that reach it here: a reader reopening a chat the idle
sweep closed, and a read that opens the chat before the restart restore reaches it.

* test(native-chat): the view-start test's starting window outlasts two subscriptions on a loaded runner

A subscription reads the conversation before it returns, so under load the two views took longer
than the create child's 300 ms start, which then exited before the test checked that it had not.
The child now takes a second to fail.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* test(native-chat): a read that reaches a crashed chat before the startup reconcile settles its turn

On desktop the chat on screen at relaunch reads before startup reconciles the leases, while the
dead process's lease still reads live. The open settles the turn it left running anyway, and the
restore that follows finds it settled.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* docs(native-chat): drop the removed dispatch hold from six comments

A worker's session no longer takes a dispatch hold, and no release clock
rests a chat by visibility; the agent-launch comments, the abandon test,
the teardown test and the refusal census still said so.

* test(native-chat): rest the owner-status chat through the idle sweep, not a hold

The activation-gate test from #22808 put its chat at rest by holding and
releasing it, and passed the release-clock grace. This branch deleted both,
so the case threw before it reached its assertions. It now moves the host's
clock past the idle window and lets the sweep stop the agent and close the
conversation, then asserts the same owner answer and activation gate.

* fix(native-chat): show the structured pane's retrying line when a read fails

The read transport always hands the pane the host's words, so the error
state's "Orca keeps trying to load it" line, which showed only when there
were none, was never seen: the pane showed the host's text twice, as its
subtitle and on the status line under it. The structured pane now always
says its read keeps retrying, and the host's text stays on the status line.
The terminal-backed chat is unchanged.

* test(native-chat): wait for a send's background start before the refusal oracle removes its store

An accepted send wakes the delivery loop, which starts the agent in the background. The oracle's teardown disposed the loop but did not wait for that start, so its lease write could create a temp file in the store directory while the directory was being removed, failing the test with ENOTEMPTY about one run in four. The teardown now drains tracked starts before it closes the journals.

* fix(native-chat): a start a message waited on gets one failure row, the delivery loop's

When a queued message's start failed, two writers could report it under the same row: the delivery loop, when the adapter settled the start without proving it, and the exit settlement, when the child's exit landed. The last one won, so the chat's row could name a different cause than the one the message was rejected with, or be written twice.

The exit settlement now writes the start's row only when no message is queued and the loop has not already recorded that start. A start for a command, goal change or rewind, with nothing queued, still gets its row from the exit.

Brennan BensonandClaude bfe476f922 fix(native-chat): a message is accepted, then delivered (#22821)
* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

* docs(native-chat): stop citing the removed handoff in lifecycle comments

Six comments still named the handoff coordinator, a handoff suspend, or a
terminal-owned session as live participants in the flows they describe.

* test(native-chat): pin that a start dead before proving owes no settlement

The removed restart handoff test pinned this branch; nothing else did.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* fix(codex): settle a structured send on admission, and stop minting a colliding identity

Two sends could be written into the journal under one durable identity.

Codex coalesces a mid-turn `turn/start` into the running turn rather than
refusing it -- measured against real `codex app-server` builds 0.147.0,
0.150.1 and 0.153.4, none of which refuse and none of which fire a second
`turn/started`. The dispatch path read the turn id from the turn/start
response and stamped every accepted send `ordinal: 0`. Since a coalesced
send gets the running turn's id back, two submissions persisted the same
`providerItemId`. That string is durable, and it is the key a restore uses
to match a submission against provider history, so the second message's real
history row matched nothing and rendered as an extra bubble on replay.

On 0.147.0 it is worse than a collision: the coalesced response returns a
turn id that never starts and never completes, so the persisted key named a
turn absent from history and NEITHER message could match.

Identity is now minted from the echoed user message at `identityFor` -- the
single point that mints the journal row's own identity -- so the settled key
is by construction the one replay computes, rather than a parallel
calculation that can drift.

Dispatch returns `admitted` when the transport write completes; identity
settles on the echo through a channel that did not previously exist for
Codex. Waiters are keyed by client message id instead of being shifted off
the front of an array by arrival order, and they are cleared on session
close and child exit -- previously a timeout was the only thing that ever
ended one.

`TURN_ID_WAIT_MS` is deleted. It was never reachable on any build measured:
`readCodexTurnId` returns non-null on all three, so the 10s wait never
fired. The comment justifying it claimed older builds acknowledge before the
id exists, which no tested build does.

Three comments asserting Codex answers a mid-turn send with `turn already
running` are corrected. Their only backing was a test fixture inventing that
error string. The correction is factual only -- every changed line in
`src/main/runtime/orchestration/` is a comment, and mid-turn delivery is
still refused for both providers. Whether that policy is right is a separate
question; it was resting on a false premise.

Known gap, stated rather than implied: this prevents new collisions and does
not repair journals already written with a colliding or phantom key. Those
conversations keep duplicating on restore. Repairing them means re-matching
persisted submissions against provider history and rewriting
`providerItemId` -- which is what `journal-submission-reconciler.ts` is
written for, and it still has no production caller.

* test(codex): drop the synchronous-accept contract and the colliding `:0` from the integration fakes

Three tests in the structured-session integration suites encoded the dispatch
contract this branch replaces, and two of them pinned the defect it fixes.

They asserted `agentSession.send` answers `dispatchState: 'accepted'` carrying
`providerItemId: codex:<thread>:<turn>:0` at send time. That ordinal was never
observed; it was stamped on every accepted send, which is exactly the collision
this branch removes -- a send coalesced into a running turn is answered with the
running turn's id, so two submissions persisted one durable key.

The visible failure was a 30s timeout rather than a failed assertion. The fake
client advertised no `agent-session.pending-send-result.v1`, and without it the
host holds the reply until the send settles: a shim for clients too old to
render a pending bubble. The fake provider then echoed the user message with no
`clientId`, so nothing could correlate that echo back to the submission, and the
wait ran to its own 30s ceiling. Real Codex sends `clientId` on that echo, and
the fake now does too, which is what makes it a model of the provider rather
than a sketch of one.

The identity assertion is kept rather than dropped. Each send now asserts
`pending` with no identity at admission, then asserts the submission settles
`accepted` at `codex:<thread>:<turn>:0` once the echo lands. Same ordinal, but
earned from `identityFor` on the echo -- the key a replay recomputes -- instead
of guessed from the turn/start response. Ablated: removing `clientId` from the
two echoes leaves both submissions `pending` and fails both assertions, so the
assertion is load-bearing and not satisfied by something incidental.

Both suites' client fixtures now advertise the capability set the desktop
renderer sends in `src/main/ipc/runtime.ts`, which is what these suites mean by
a client. The older-client settlement wait keeps its own coverage in
`src/main/runtime/rpc/methods/structured-agent-session.test.ts`.

`structured-agent-session-runtime-exit.test.ts` asserts `pending` for the same
reason; it drives the host directly, so it never took the compatibility path,
and what proves delivery there is still the turn the reacquired provider starts.

The replay suite's "without dispatching it twice" property is untouched: one
`turn/start` call, one replayed ledger row.

* fix(codex): preserve unsettled dispatch correlations

* test(codex): type the dispatch fixtures instead of asserting over them

main's new casting gate (#20367 base) flags type assertions on changed
lines. Replace them with checked types: the recording sink already
satisfies its interface, both CodexSession fixtures are now annotated and
carry real collaborators, the settlement assertion compares whole
identities, and the integration helper reads submissions through the
host's public journalSnapshot instead of its private session map.

* fix(test): merge the duplicate doubt-reasons import the merge left behind

Both sides added an import from journal-dispatch-doubt-reasons and the
merge kept both statements, which the whole-repo native plugin gate
refuses under --deny-warnings.

* test(codex): a Fast mode turn is admitted, not accepted

#20506 landed its Fast mode tests against the dispatch contract this
branch replaces: a Codex send now returns admitted and settles its
identity on the provider echo. The tier assertions the test exists for
are untouched.

Brennan Benson 539d4d1f32 fix(native-chat): resume structured chats cleanly after restart (#20509)
* fix(native-chat): retire provider ownership on restart

* fix(native-chat): stop showing a restart eviction as a provider death

Restarting Orca turned a resumable structured chat into a user-visible
`Provider exited: recorded pid absent on host`. Quit never released the durable
lease, so restart probed the recorded pid, adjudicated the session evicted, and
wrote a synthetic status row against a chat that was perfectly resumable.

The fix is the missing teardown phase plus the missing fence check: quit now
evicts every provider child this host owns — stopping it, settling its journal
and handing the lease back — and the release compare-and-swaps on the fence it
expected. Restart then finds a released lease and reopens the chat silently.

What the user sees is decided by the typed death evidence rather than the shape
of a settlement id: only an `exit-observed` death writes copy, and that copy now
carries its cause so an auth failure and an OOM kill do not read alike. The
reassuring wording stays. Historical synthetic rows are filtered out of the
render projection, which needs no schema change and leaves every real
provider-exit row alone.

Also:
- Bound the new eviction phase well below the quit deadline; a quit that dies
  mid-eviction leaves the lease unreleased, which is the original bug.
- Scope the interruption verdict to work that was mid-response. A provider that
  died while waiting on an approval interrupted nothing.
- Keep host bookkeeping in step with the adapter: the provider-child flag clears
  when the child is proven stopped, not seven steps later.
- Drop the router's duplicate shutdown gate and acquisition drain — both
  adapters already own theirs — and latch the router closed so a late acquire
  cannot fan a session back out to closed adapters.
- Attach the real cause to the settlement failure a quit reports, and remove a
  recovery-ticket field that was hardcoded at its only construction site.

* fix(native-chat): scope the legacy status filter to the copy it retires

The read-time filter hid every status row carrying a `restart-eviction:`
identity. That identity is still minted, so a genuine provider death settled
under it would have been dropped from every rendered page. Match the retired
`Provider exited` copy as well, so only the legacy rows are hidden.

Three smaller corrections alongside it:

- The settlement retry path now applies the same unfinished-work check the
  live exit path uses, so a provider that died waiting on an approval no
  longer gets told a response was in progress.
- Bound the exit reason before composing the outcome copy, so a stderr dump
  in the reason cannot push the "you can continue" sentence past the row's
  byte cap.
- Correct the teardown comment: tail rows are protected by eviction's own
  per-session ordering, and `closeAll` is a backstop for children eviction
  never took, including one whose eviction was refused.

* fix(native-chat): retire legacy status rows at the projection source

The read-time filter that hides the retired `Provider exited …` rows ran on the
way OUT of the page builder, after the paging math had already measured the
unfiltered timeline. A backward window landing entirely on those rows returned
an empty page that still reported `hasOlder: true` with a null `window.oldest`,
so the renderer's backfill loop re-asked from the same anchor forever. Its only
no-progress guard compares `window.oldest?.sequence` to the anchor, and
`undefined === n` never breaks. The live subscription opens behind that loop, so
the transcript never finished loading either.

Filter where items ENTER the page pipeline instead: the reduced snapshot gets
one renderable timeline, the forward path gets one renderable batch, and the
window bound, effective limit, `hasOlder`, `window.oldest` and `nextCursor` are
all computed over that single array. A window with nothing left behind it now
reports end-of-history.

Also restore the eviction retry contract. Clearing `hasProviderChild` as soon as
the adapter proves the child gone is honest, but it is a different fact from the
wind-down this host still owes. A retry after a step aborted between the two was
reading "no child here" and skipping both the dead-generation settlement and the
lease release the aborted attempt had promised to repeat. The obligation is now
tracked separately and cleared only by a release that actually landed.

And rename the filter to the copy it retires: it drops only rows carrying the
retired `Provider exited` text, not restart-eviction status rows in general.

* fix(native-chat): read the wind-down a close owes from the live child

An eviction recorded "nothing owed" whenever it ran over a session with no
provider child of its own, and the retry then read that record in preference
to the child in front of it. A session suspended to an agent terminal is
exactly that shape, and the trip back to native re-acquires into the SAME
session object rather than replacing it, so the next close skipped both the
dead-generation settlement and the lease release — leaving the record claiming
a live owner this host had just stopped, and a pending send unsettled.

The obligation is now derived the way the quit sweep already derived it, from
one shared predicate: a live child always owes a wind-down, and a remembered
`false` only carries the obligation forward, never cancels it.

Also drops a memoization in the history page that could never hit. Its key was
the snapshot's items array, which the reducer rebuilds on every `snapshot()`
call, so each backward page allocated a fresh key; the one reader that does
share a snapshot across pages reads forward and never calls it. The comment
claimed a multi-page read filtered once, which was not true of either path.

Tests: the handoff round trip that strands the lease, and the quit sweep
picking up an eviction whose close retry never came.

* chore(native-chat): scope three helpers to their file and pin the teardown order

retryUnexpectedExitSettlement, hasUnfinishedStructuredAgentSessionWork and
isRetiredProviderExitStatusItem each have no consumer outside the file that
defines them, so they no longer advertise an external contract.

The quit-path phase list documents its order as load-bearing, but nothing
asserted it. Pin the phase names so evict-owned-sessions cannot drift out of
its slot between drain-attaches and flush-event-sinks.

* fix(native-chat): stop the router reporting a stop it never observed

`closeAll` cleared the route table and set one boolean, after which that boolean
was the only surviving evidence about any session. Two call sites then spent it:
`releaseAcquisition` and the stop path each turned a route-lookup MISS into
reported success. Eviction reads a `true` from the stop path as proof the
provider child is gone and releases the durable lease on it, so a session the
router never routed could have its lease handed back on the strength of "I have
no record, but everything is closed."

Loss of contact is not evidence of process death. The fix keeps the evidence
instead of the inference: adapter shutdown only resolves once every child is
proven stopped, so `closeAll` now marks each routed session `stopped` rather
than forgetting it. A routed session still answers `true` from its own retained
proof; a session with no route answers `false`, which leaves it indexed for a
real retry. `releaseAcquisition` drops its short-circuit and asks the adapters,
which answer from their own session maps.

The acquire-side latch is unchanged: once closed, the router stays closed and
refuses new work.

Behaviour that changed: a post-`closeAll` stop for a session the router never
routed, or one the host already acknowledged as released, now reports unproven
instead of proven. That matches what the same call already answered before
`closeAll`, and no real flow reaches it — quit evicts every owned session before
`closeAll` runs, and eviction only asks the adapter for sessions whose provider
child this host acquired through the router.

* test(native-chat): ratchet the retired provider-exit copy out of production

The retirement filter hides a status row on two facts: a restart-eviction item
id and copy that opens with the retired prefix. The identity half is still
minted today, so the filter cannot tell a new producer's row from the legacy row
it exists to hide — any future writer of that copy would be dropped from every
transcript with no trace. Until now that safety property lived only in a doc
comment.

Scan the shipped tree for a string literal that OPENS with the retired prefix,
which is exactly what the filter's `startsWith` reads. Comments are stripped
first, so prose about the retirement is not a producer, and the filter's own
constant is exempt. Tests are excluded: writing the copy is how the filter is
exercised.

* revert(native-chat): drop the read-time retired provider-exit filter

Fix forward instead. The lifecycle change in this branch stops any new
`Provider exited: <reason>` row from being written; rows a previous build
already persisted stay in those transcripts and age out with them. A
permanent read-time filter for a cosmetic, shrinking set was not worth its
maintenance cost, and its paging seam was the only place a backward window
could land entirely on hidden rows.

Removes the filter module and its test, restores agent-session-history-page.ts
to its pre-branch form, and drops the tests that only existed to prove the
filter did not over-match or wedge the backfill loop.

The copy ratchet stays and now carries the whole guarantee: with no filter in
front of it, any production writer that resurrects the retired prefix reaches
the user's transcript directly.

renaming it would have carried out-of-scope handoff code into the merge. Body preserved as evidence

The journal opener moved to journal-store-factory on main; retarget the

* fix(claude): resolve Claude structured launch args, auth, and win32 proof

The origin/main merge re-expressed the lane's Claude wiring onto main's split
orca-runtime facade and dropped three wires past green typecheck and lint.

- resolveLaunchArgs discarded its provider parameter, so structured Claude
  sessions were launched with Codex app-server flags; Claude exits on
  --dangerously-bypass-approvals-and-sandbox, and a Codex arg-parse throw
  could block Claude session creation outright.
- resolveClaudeLaunchEnv was no longer supplied, so the launch resolver fell
  back to the whole process env as configuredEnv and
  buildClaudeChildProcessEnv re-applied every auth var it had just stripped.
  The resolver now merges the Claude overlay onto a strip-applied copy of the
  inherited env, which also keeps PATH intact for withCliRuntimeOnPath.
- The windowsProcessStartTimeAvailable producer was gone while the contract
  field and both consumers survived, so the renderer gate fail-closed and
  structured native chat was unreachable on every win32 host.

Separately, structured Claude pinned CLAUDE_CONFIG_DIR unconditionally. An
explicit pin makes the CLI abandon the macOS Keychain even when it names the
CLI's own default, so a default claude.ai account could not authenticate where
the legacy Claude terminal could. Pin only a home the CLI would not resolve on
its own, matching ClaudeRuntimePathResolver, and compare against the env the
child would otherwise inherit so a diverging overlay cannot outrank the
record's account home.

Also await the now-async revealNativeSession in its regression test, and set
the native status before revealing so a rejecting reveal cannot leave a
session released but never marked native.

* fix(claude): scrub case-insensitive Windows auth env

* fix(native-chat): settle handoff outcome-write failures instead of leaking them

A store write failure while recording a handoff outcome escaped the flow
runner's catch handler, so the client never received the failure and the
flow surfaced as an unhandled rejection (seen as an intermittent
agent_session_store_corrupt error in the proven-dead-retry suite, whose
teardown raced the flow's trailing outcome write). Record the failed
outcome best-effort, and drain the coordinator before that test's
teardown removes the store root.

* fix(native-chat): make the structured close-failure toast provider-neutral

The structuredSessionCloseFailed toast fires for any structured session,
but its copy said 'Codex chat', so a Claude structured session that fails
to close showed the wrong provider name. The launch-failure toast is only
reachable behind the agent === 'codex' gate, so its copy stays as is.

The one `experimentalStructuredNativeChat` toggle gates both providers —

`'claude'` as well as `'codex'` — but its description named only Codex.

Its scope line also said Windows keeps using terminal chat, while the gate
refuses win32 only until the host proves it can read a process start time.
`structured-native-chat-availability.test.ts` already pins that Windows is
allowed once the proof is cached, so the two contradicted each other.

* test(claude): pin @anthropic-ai/claude-agent-sdk 0.3.251 contracts against a scripted CLI

PR 1 of the SDK migration: dependency + test-only harness, no product wiring.

- Pin @anthropic-ai/claude-agent-sdk to exactly 0.3.251 — not the newest
  release — because 0.3.251 (published 2026-08-28) clears the repo's 3-day
  minimumReleaseAge supply-chain gate with no exclusion, while the newest
  release was minutes old and would have required excluding a brand-new
  publish from the exact control built to catch brand-new malicious
  publishes. Every contract this design depends on was verified identical
  on 0.3.251: the full option surface, no pid on SpawnedProcess (custom
  spawner stays mandatory), env defaulting to process.env when omitted, and
  --replay-user-messages appearing only via extraArgs.
- Exclude all eight bundled CLI platform binaries via
  ignoredOptionalDependencies. The setting lives in pnpm-workspace.yaml
  because pnpm 12 no longer reads the package.json "pnpm" field (it warns
  and ignores it; verified by install ablation). Excluding the binaries is
  what makes Orca's pathToClaudeCodeExecutable override mandatory rather
  than merely preferred. Note: pnpm 12.0.0 honors the ignore list when
  reconciling an existing lockfile but not on fresh resolution of a new
  dependency, so the lockfile's SDK entry was pinned surgically; both
  'pnpm install' and 'pnpm install --frozen-lockfile' verify clean and
  stable against the committed lockfile.
- Contract-pin suite drives the real SDK against a scripted fake CLI and pins:
  unknown type/field/content-block pass-through (and keep_alive interception),
  spawner env fidelity plus the omitted-env process.env inheritance sharp edge,
  extraArgs producing --replay-user-messages, argument parity for every
  CLAUDE_STRUCTURED_BASE_ARGS entry plus --session-id/--resume/
  --resume-session-at, canUseTool wire request_id stability and abort on
  control_cancel_request, one spawn per query, pathToClaudeCodeExecutable
  honored by the default spawner, the exact SDK version, and the eight platform
  binaries staying uninstalled.

* feat(claude): drive the structured transport through the agent SDK

Replaces the hand-rolled `claude -p --input-format stream-json` transport with
@anthropic-ai/claude-agent-sdk 0.3.251, keeping the existing connection
interface for this commit so the acquisition path changes minimally. The
control-plane rewrite is a separate change.

Orca still supplies the process. `spawnClaudeCodeProcess` routes through
`spawnProcess`, retains the child and its pid — the triple the durable lease
adjudicates on — drains stderr so exit errors keep their tail, and hands `.cmd`
shims to Orca's Windows argument encoder rather than the SDK's plain spawn.
`close()` keeps Orca's own bounded tree-kill and exit deadline, so it still
resolves true only after an observed exit.

Launch resolution emits an SDK options object instead of argv; durable
`launchArgs` translate to a typed option where one exists and to `extraArgs`
otherwise, refusing a token neither can carry rather than dropping it. The
child env is always passed explicitly — omitting it would let the SDK inherit
`process.env` and reintroduce the ambient `ANTHROPIC_*` leak. The stdout line
parser is deleted; the SDK owns framing, and unknown frames still reach the
translator verbatim.

* fix(claude): settle the frame the SDK pulled but never wrote

The SDK's input pump is `for await (frame of prompt) { await transport.write(frame) }`.
When that write rejects — the child dies between Orca's liveness guard and the
write — the for-await ends abruptly and calls the generator's `return()`, so the
code after `yield` never runs. The frame was already shift()ed out of `queued`,
so the later `fail()` from the exit path could not reach it and `send()` never
settled: `dispatchClaudeTurn` awaits that send before it can return `unknown`,
wedging the caller and the durable outbox. The pre-SDK transport rejected on the
stdin write callback instead.

Retain the in-flight entry and settle it from the generator's cleanup, and let
fail() reach it too for the pump that never resumes at all.

Claude-Session: https://claude.ai/code/session_01AobxxokqQ3qcxS7sy7ckum

* fix(claude): keep the agent SDK behind the structured-Claude boundary

The ordinary OrcaRuntimeService graph statically reaches the Claude adapter and
so the transport module, whose first line imported @anthropic-ai/claude-agent-sdk.
The SDK is evaluated whenever the regular runtime loads, before any structured
Claude session is chosen: it sets process.env.NoDefaultCurrentDirectoryInExePath,
changing Windows executable resolution for later subprocesses, and a missing or
incompatible install would break normal runtime startup — for a user who never
leaves the terminal/TUI path.

Defer the SDK to the connection, memoized so it loads once per process, and add
the import-graph ratchet: a walk from the Electron main entry that fails on any
static import of the package, plus a clean-fork check that loading the runtime
leaves the Windows search variable untouched and a child-process pin that the
side effect is still real.

* fix(claude): answer list_models so the picker stops serving the seed

sendControlRequest had no list_models case, so every request hit the default
reject; readClaudeStructuredSessionOptions swallows that with .catch(() => null)
and falls back to the static catalog. Every structured session therefore served a
hardcoded model list with no per-model effort levels, no resolvedModel and no
default detection, and nothing surfaced the failure. The pre-SDK transport got the
live catalog from the CLI.

Route it through the SDK's supportedModels(), wrapped in the { models } envelope
the existing parser reads.

* fix(claude): reap the child's descendants before killing it

The forced step of the exit ladder went through the Codex helper, which spawns
`pkill -KILL -P <pid>` and SIGKILLs the parent in the same tick: the parent
usually dies first, the descendants reparent to pid 1, and `-P` matches nothing.
An MCP or launcher descendant of a stubborn Claude child was left running. The
test named for that requirement declined to assert it and killed the survivor by
hand instead, so it could not fail for the thing it was named after.

Route the Claude reap through Orca's existing sweep, which snapshots descendants
while their parent link still exists and signals them before the root goes, and
on Windows uses the identity-gated `taskkill /T /F`. The test now asserts the
descendant is dead; the manual kill stays only as a failure-safe. close() still
returns true only on an observed exit.

* fix(claude): answer a permission callback whose signal already aborted

settleFrom registered the abort listener and then delivered the request. A

stayed pending behind a durable prompt with no cancel path. Check the signal
first, emit the cancel, and resolve the SDK's null sentinel without registering.

* test(claude): wait for the child to record the frame, not just for its report

file.

* fix(claude): coalesce partial deltas onto one assistant item and stop painting result frames

Under --include-partial-messages every stream_event frame carries its own
uuid, and the final assistant frame for a block carries yet another; only
message.id ties them. The translator keyed each delta by its frame uuid, so a
reply painted as one bubble per delta chunk followed by a complete duplicate
under the final frame's uuid. The block's first stream frame now mints the
claude:(sessionId, uuid) identity, deltas coalesce onto it through the shared
60ms seam, and the final frame reconciles onto that same item.

Known SDK bookkeeping no longer reaches the provider-fallback row: result
subtypes are catalogued and settled by the turn lifecycle, an empty thinking
block (redacted thinking) is a modeled kind, a string-content user replay is a
text block, and an empty user frame paints nothing. An unmodeled result
subtype or content kind still lands on the bounded fallback row.

* fix(claude): prove descendant exit at the close boundary instead of on an unref'd timer

close() reported proven=true as soon as the direct child exited while the
descendant sweep's SIGKILL sat on an unref'd 2 s timer, so a SIGTERM-resistant
MCP server outlived the lease release. The reaper now composes the same shared
primitives the Codex structured provider uses: snapshot, verified bounded
descendant termination on POSIX, taskkill /T /F on Windows. The proof is false
whenever descendants outlive the deadline, a retried close re-verifies the
retained snapshot rather than trusting the dead root, and the raw pipe child no
longer goes through the PTY job sweep it never owned a job for.

Measured on macOS: a killed child of a SIGSTOPped parent stays a matching zombie
row in ps, so the root is killed while verification runs rather than stopped
first as the Codex non-group path does.

* feat(claude): replace the hand-rolled control plane with the SDK's native surface

PR 3 of the Claude structured SDK migration removes the wire-frame scaffolding
PR 2 kept, so Orca drives the SDK's typed control surface directly.

Inbound permissions move from a rebuilt control_request dispatch to the SDK's
canUseTool / onUserDialog callbacks. The prompt registry now carries the
callback's own resolver: a decodable can_use_tool becomes a durable prompt whose
answer settles the callback; a malformed one is denied without registering; the
SDK's abort signal (fired on control_cancel_request, which the SDK matches and
dedups itself) forgets the prompt and settles it null, and a late answer after
abort finds no prompt and is refused. Closing settles every in-flight callback so
no promise dangles. The claude-agent-sdk-control-bridge that rebuilt the wire
frame is deleted.

Outbound control maps to Query methods: interrupt() for cancel, setModel /
setPermissionMode / applyFlagSettings for options, supportedModels for the model
list, initializationResult() for init proof, each under Orca's own request
deadline and error classification. Cancel is interrupt-receipt aware: a CLI
advertising interrupt_cancel_queued_v1 gets cancel_queued in one round trip,
otherwise the receipt's still_queued uuids are swept with cancel_async_message so
a cancelled turn cannot spawn a later unexpected turn; older CLIs resolve no
receipt. Init keeps the 10s deadline and the unauthenticated-startup guidance.

Every behavior is failing-first and ablation-proven; the toggle-off import
boundary and the accepted loss of unknown-control visibility rows are unchanged.

* fix(claude): arm the descendant snapshot before stdin closes and make the tree verdict unproven by default

A healthy Claude root leaves within the graceful window, and the close ladder
only snapshotted descendants when the root was still alive after that window.
So the common close never looked at the tree: `treeExited` stayed null,
`!== false` passed it, and close() reported a proven exit with an MCP child
still running. A root that died before the walk made the snapshot vacuous too.

The proof is now unproven by default. The reaper holds one verdict in Orca's
vocabulary (exited / live / unverifiable), assigned in exactly one place from
the bounded verification, and close() returns true only on `exited`. The
snapshot is armed before stdin closes, while the root can still be walked, and
is verified after the root exits; a root that left before any snapshot could
be armed stays unverifiable rather than vouching for descendants it never
showed us. The shared verifier gains the three-way verdict behind its boolean
face, and the connection reports the root and tree verdicts separately along
with the child's exit status.

One verification per close attempt: the retried close re-verifies, so the
intra-attempt re-reap is gone from the teardown budget.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): verify the Windows tree after taskkill instead of trusting that it ran

`terminateWindowsProcessTree` resolves from taskkill's callback whatever the
error says, so a timeout, an access denial, a recycled root and a surviving
descendant all looked identical to the reaper — which then returned a proven
exit unconditionally. close() reported true and the lease was released with an
MCP descendant potentially still live.

The Windows branch now snapshots the root's descendants while it is alive and,
after taskkill, polls a fresh process table to a bounded deadline: a row still
matching by pid AND creation time is `live`, an unreadable table is
`unverifiable`, and only a table with no match is `exited`. Creation time is
the PID-reuse guard the POSIX path gets from ps lstart, so a descendant that
denied a creation-time query is omitted rather than signalled on a bare pid.
A root already observed exited is never taskkilled: `/T /F` on a recycled pid
would take an unrelated tree down with it.

The captured tree is tagged by platform so neither verifier can be handed the
other's rows.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): release a reservation on a first-hand root exit instead of latching it into manual recovery

Making close() strict about the descendant tree exposed a second defect at the
same boundary. A create-time acquisition has no ownerProcess until publication,
so an unproven cleanup mapped to handoffStage `manual-recovery`, and
adjudication then refuses every later attach with agent_session_ownership_unknown.
A user who was merely signed out, or whose --resume the CLI rejected, wedged the
session id permanently.

Each question now answers from its own evidence. close() is unchanged and stays
strict about the tree. Separately, the lease is keyed on the root's pid and
start time, so when Orca's own child handle observed that root exit and no
descendant snapshot was ever admissible, the reservation is released and the
CLI's exit code and stderr reach the user. A descendant observed still alive,
or a root Orca never saw leave, stays unproven and keeps the reservation.

The settlement records only what was observed: the released lease says the
provider process exited and its descendants were not verifiable, rather than
reusing the wording that claims cleanup proved no child remains.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): surface an API error a result frame reports instead of settling the turn on it

The SDK models an API failure as a SUCCESS-subtype result whose `result` string
is the user-facing error text, with no assistant frame behind it. The translator
suppressed every catalogued result subtype as turn bookkeeping, so that turn
tombstoned its lifecycle and showed the user a completed, empty reply with no
sign anything had failed.

Suppression is now by meaning. A result reporting a failure routes to the
bounded provider-error surface, leading with the provider's own sentence and
keeping the raw frame behind the row's disclosure; ordinary successful results
stay off the timeline as before. A turn the user aborted also stays suppressed:
its interrupt frame already says so, and its execution diagnostic would only be
noise on every stop.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): drop the stream state of turns that never received their final frame

Every streamed delta recorded its block's identity, latest text and checkpoint
length. Only the final assistant frame removed them, so an interrupted turn left
its whole accumulated reply reachable until the session was disposed, and a long
session with repeated interruptions grew those maps without bound. The partial
text was already journaled by the flush that precedes settlement, so the live
copy was pure retention.

That state now lives in its own module, named for what it does — grow a streamed
block's journal row between its deltas and its final frame — and turn settlement
drops every block still awaiting a final. The translator reports how many remain,
which is the invariant: a settled turn leaves none.

Also makes a timed-out process-table read retryable while the root is still
alive. A loaded host can miss the table's one-second deadline, and latching that
as "no descendants" both lost the descendant sweep and, on a busy machine, made
the close ladder report unproven for a tree it never actually looked at. Only
the root's death still makes a missing snapshot final.

* perf(claude): capture the Windows descendant tree from one process-table read

The capture walked the descendant tree and then read the table again for the
creation times the walk's projection drops. Each read is bounded in seconds and
both run inside the close ladder's budget, so the second one cost the worst-case
teardown three seconds for data the first read already held.

The walk is now exported from the module that owns it and runs over rows the
caller has already read, which is also what lets the snapshot keep the
PID-reuse guard the projection cannot carry.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(pty): spend the descendant verification window instead of surrendering on one slow table read

The verification abandoned the whole check the first time a process-table read
missed its own one-second deadline, with seconds of its window still unspent.
On a loaded host that reported a tree unverifiable without ever having looked at
it, which the Claude close ladder then turned into an unproven close and a
retried teardown. It also made the descendant-exit tests flake under a parallel
suite run, for the same reason and with the same honest-but-premature verdict.

A read that missed its deadline is now simply not an answer: the loop waits and
reads again until its own deadline, and only a window that ends without a
readable table reports unverifiable. This can only turn a premature verdict into
one backed by evidence; it never manufactures a proof.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): never let a later failed look collapse an observed live descendant into unverifiable

The reaper's single assignment site latched only 'exited', so a second reap
whose table reads all missed their deadline overwrote an earlier completed
verification's 'live' with 'unverifiable'. The acquisition release gate
discriminates on exactly that pair, so a root exit after such a decay released
the lease over a descendant that had been observed alive. The latch is now
monotone in trust order: exited is final, and live is only ever raised to exited.

Claude-Session: https://claude.ai/code/session_01HfdhsvSJucLw4cTZxzg2CP

* fix(claude): never prove a Windows tree gone while a descendant denied identification

The Windows snapshot dropped rows that denied the creation-time query, and an
emptied snapshot was judged exited without any table read: a descendant Orca was
refused information about was treated as one that had left. The snapshot now
counts the unidentified rows it saw, and verification caps its verdict at
unverifiable while any exist. Nothing is ever signalled on a bare pid, as before.

Claude-Session: https://claude.ai/code/session_01HfdhsvSJucLw4cTZxzg2CP

* fix(claude): classify cleanup after a first-hand exit as a root exit instead of a proven tree

When the CLI died between a successful acquire and the host's commit or proof
of the lease, handleExit had already removed the session, so releaseAcquisition
found nothing and reported true. The attach flow then settled exit-proven with
deathEvidence claiming cleanup proved no provider child remains, though the
tree was never verified. The adapter now keeps the exit that removed a
published session until the session is acquired again; acquisition cleanup runs
that connection's close ladder and classifies its verdict exactly as a
start-time failure would be, so the record reads root-exit-observed. The wire
helper keeps that typed classification and its provider diagnostic instead of
wrapping it as unproven, and the router gives up its owner even when the
release throws.

* fix(claude): restore the root SIGKILL fallback the identity gate took away

The direct root kill goes through the handle Node owns, not through a pid:
libuv drops that handle in the same turn it reaps, so the signal either
reaches the process Orca spawned or reaches nothing at all. Gating it on a
process-table probe therefore bought no safety and cost the tree its only
fallback whenever the probe declined -- a first capture landing in the fork's
own second, a recycled descendant pid voiding the snapshot, or a process table
that could not be read on either platform.

Identity verification stays where a bare pid is genuinely addressed: Windows
`taskkill /T /F`, and the descendant sweep's own revalidation before it signals.

Also stops a declined root probe from collapsing an observed `live` or `exited`
descendant verdict into `unverifiable`, and stops a successful taskkill from
reporting `unverifiable` because a later probe found the root correctly dead.

* docs(claude): rewrap the root-kill ordering comment

* Match the Claude structured launch to the terminal path's managed-account auth rules

The SDK path stripped ambient Anthropic auth unconditionally, let an explicit
agentDefaultEnv override beat a pinned managed account, and had no account-switch
guard. Reuse the terminal preflight's own predicate and messages so both transports
strip, refuse, and report identically, and cover the CLI transcript location that
mobile native chat depends on.

* Reach the Claude structured chat lane from the desktop UI

The main process has had a complete, correctly gated Claude Agent SDK lane for
a while, but no renderer ever asked for it: the launch route accepted only
`codex`, and the create path was typed `agent: 'codex'` end to end.

Widen both to the structured provider union that already exists
(`AgentSessionHandleProvider`), and generalize the codex-named create path
instead of adding a Claude twin beside it. The pending-launch registry is now
keyed by agent as well as workspace — a shared key handed a second caller the
first agent's intent, so a Claude and a Codex launch in one worktree collided.

Windows, per agent. Codex's client-side win32 refusal is deliberate and settled
elsewhere, so it stays exactly as it was. Claude's answer is no longer guessed
from the client's platform: a structured session fences its provider child on
that child's process start time, and only the executing host knows whether it
can read one. `agentSession.createSupport` already answers precisely that, per
agent, and had no renderer caller — so the Claude create path asks it before
creating and turns a "no", or a probe it cannot get answered, into the
definitive refusal the launch fallback already handles. Fail closed either way.

That refusal mapping also closes a real gap: the host reports an unsupported
location by throwing `structured_agent_session_unsupported`, which reaches the
client as a transport rejection rather than a refusal envelope, so
`StructuredAgentSessionCreateRefusalError` never fired. The launch would retry
the create, strand itself in `visibilityUnknown`, run no legacy fallback, and
show an error toast.

Close a fail-open hole while Claude and win32 become reachable: `create` with a
client-supplied location, and `ensure`, both skip the worktree-resolving support
check. They now ask the executing host the same question directly, so a host
that cannot fence a provider child no longer creates one on a client's say-so.

Also deletes `structured-agent-session-provider-routing.ts`, a duplicate of
`structured-agent-session-provider-support.ts` with no importers.

WSL, SSH and paired hosts, floating workspaces, draft prompt delivery, explicit
TUI customization and initial session options all keep refusing; folder
workspaces keep working.

* P1-1: make the structured Claude auth policy required and testable

The optional dep plus a {stripAuthEnv:false} fallback meant a dropped wiring
under-stripped silently. Required at all three hops, asserted at install time for
the @ts-nocheck caller, and the settings-to-policy mapping is now a named tested
function.

* P2-3: mobile's default Claude transcript root must follow CLAUDE_CONFIG_DIR

session-file-resolver's default ignored the variable the pinned account home
follows, so a CLAUDE_CONFIG_DIR launch wrote one tree and mobile read another. The
Task-4 test now resolves with no root override (mobile's own call) and checks the
answer against the root the CLI itself reports, instead of mirroring the code under
test's own expression.

* P2-1/P2-2/P3: close the teardown window, join the live-auth gate, align the refusal

P2-1: a switch beginning inside the acquire teardown left a dead chat and no
replacement. Past that point the launch waits the swap out and refuses only if it
never settles; the entry guard still refuses outright, because nothing is torn down
there yet.
P2-2: structured children now hold the same OAuth-refresh gate a Claude PTY does,
so a managed refresh cannot rotate the token out from under a live turn.
P3: the refusal now matches the strip it guards (case-folded on win32, presence not
truthiness), and the dead structured-to-TUI builder states its auth policy instead
of silently signing a system-auth user out.

* Make the live-auth gate tests independent of sibling connection teardown order

* Do not offer structured Claude under a WSL-only managed account

Structured Claude launches against the ambient Claude config, which the account
service keeps in sync with the selected HOST account. A WSL-bound managed
account lives inside the distro and is never synced there, so on Windows a
structured session would authenticate as whatever the ambient identity happens
to be while the UI names the WSL account — the user is told one identity and
given another.

That was unreachable only because nothing offered structured Claude on win32.
Enabling it makes it reachable, so gate it here rather than patching the auth
layer: refuse the structured path when the active managed Claude account is
WSL-bound, and let the terminal-backed path — which resolves the account per
runtime — handle that account shape.

The answer rides the agentSession.createSupport seam the renderer already
consumes, so no new capability and no renderer knowledge of account internals.
A create the host declines becomes the definitive refusal the launch fallback
already turns into a legacy native chat tab, with no error toast.

Unknown answers refuse. An install with no managed accounts claims no identity
and is fine, but an active selection that cannot be resolved — or account state
that cannot be read at all — is not evidence that the ambient identity is right.

Claude only. Codex resolves its account through a different path and its
createSupport answer is untouched, as is every Codex routing decision.

* Read the structured Claude account gate through the auth policy's accessor

The gate resolved the active account from the account-service snapshot's
runtime map; the auth policy resolves it with
getSelectedClaudeAccountIdForTarget(settings, { runtime: 'host' }). Those are
two sources and two resolution rules, and they disagree on a legacy settings
blob that carries the selection only in the flat activeClaudeManagedAccountId:
the accessor falls through to it, a direct read of the runtime map does not. The
gate would then refuse a launch the policy would have run under host-1 — and in
the mirror case a session could be admitted under a policy computed from a
different account than the gate approved.

Read the same settings through the same accessor so agreement is structural
rather than coincidental, and drop the controller accessor that existed only to
reach the snapshot.

No behaviour change for any state both already agreed on; Codex is untouched.

* Round-3 review fixes: N-1 empty-value regression, N-2 gate leak window, N-4 lost history

N-1: my presence-based conflict predicate refused a terminal launch that works
today. 'ANTHROPIC_API_KEY=' is how a user blanks a variable and the settings
pipeline preserves that empty value; an empty override cannot beat the pinned
account and the strip removes the name anyway. Back to truthiness for the value,
keeping the win32 case folding.
N-2: enter the live-auth gate only after the exit/close handlers that release it,
so no throw in between can leave an entry nothing reconciles.
N-4: the Claude transcript resolver searches config-dir-then-default and de-dupes,
matching the Codex sibling in the same file, so adopting CLAUDE_CONFIG_DIR no
longer hides history written before it.

* Run the managed-account gate on every Claude acquisition, not just create

createSupport gates the create path, but a session's account state can change
while it lives. A reacquire after an unexpected child exit re-resolves the
launch and re-derives auth, with nothing re-checking the gate — so a session
created while supported could come back up in the refused shape. With the strip
predicate keyed on there being an active non-WSL account, the WSL-only user's
normalized steady state (accounts exist, none active) does not strip, and that
reacquire reaches the child with ambient auth while the UI names the account.

Gate at resolveLaunch, the one choke point every acquisition passes through,
refusing with the pre-spawn error the caller already handles. Same predicate as
create-time, now sharing one settings reader so the two cannot drift.

Claude only; Codex resolves its account on a different path and is untouched.

The runtime class that wires this does not typecheck its own `this` calls — a
missing hookup compiles clean — so the wiring is pinned behaviourally rather
than trusted to the compiler.

* Move the structured Claude gate out of the @ts-nocheck runtime files

Both call sites of the managed-account gate sat in files whose first line is
`// @ts-nocheck`, so neither was typechecked: three arguments to a one-argument
function plus an undeclared identifier compiled clean. New auth-identity
decision logic had no compiler behind it.

Move the verdict into a checked module that takes the two facts the runtime
owns — the adapter's answer and a settings getter — and decides. The runtime
class now only forwards. Move the gate reader's construction into the checked
installer too, so the nocheck file passes a plain settings closure and never
names a gate symbol.

Every reference to the gate predicate and its reader now lives in a checked
file, so the ablation that used to pass silently is a compile error at both the
create-support and reacquire sites.

Removing the file-level @ts-nocheck is a separate, larger job and is not
attempted here.

* Derive the gate test's auth policy from the settings under test

A hardcoded stripAuthEnv asserts a gate/policy pairing production cannot
produce, and false additionally lets launch.env inherit the runner's real
process.env. Derive via claudeStructuredAuthPolicyForSettings instead: the
gate settings type is the same Pick the policy takes, and both resolve the
account through getSelectedClaudeAccountIdForTarget.

* Pin the absent-vs-empty distinction in the managed-account gate

An empty claudeManagedAccounts array is a real answer: the user has no managed
accounts, nothing claims an identity, and the ambient path is legitimate. A
readable settings object with no such field is settings we failed to parse —
the same unknown as unreadable — so it refuses.

The two are one character apart in the code and the difference is invisible
without the reasoning, so record it at the branch and pin both sides. The test
fails under the obvious "consistency fix" of treating a missing field as empty.

* fix(claude): keep command queue bookkeeping out of the transcript

Claude Code 2.1.258 emits a `command_lifecycle` frame for every uuid-stamped
command it starts, completes or cancels. The frame carries a command uuid and a
state and no content, and the CLI keeps it out of its own transcript -- but it
is absent from the SDK's SDKMessage union and so from Orca's frame catalogue,
where an uncatalogued kind defaults to a substantive row. Every structured turn
therefore painted raw JSON rows into the user-visible transcript.

Catalogue it and disposition it as status chrome. The unknown-kind default stays
`timeline-substantive`: a kind we have never seen is likelier to carry content
than to be chrome, and a visible row we can catalogue later beats content we
silently dropped. A lifecycle state that reads as a failure still surfaces,
because the payload error check in `classifyProviderFrame` outranks the
catalogue.

* fix(claude): let a re-walked descendant become eligible for the forced sweep

A descendant first observed by a capture inside its own birth second could never
be SIGKILLed: `ps lstart` is second-resolution, so that capture cannot rule out
a pid recycled later in the same second, and the merge pinned each retained row
to the boundary of the walk that first saw it. SIGTERM-resistant children forked
in that window were signalled and then never escalated -- they survived close,
quit and restart, reparented to init, and had to be killed by hand.

Advancing that boundary on any later capture would be unsound: a later capture
matching pid, pgid and start-second is exactly what an impostor would also show.
But a capture is not a match -- it is a fresh ppid walk from a root Node pins
through its own handle, so a row it re-derives is proved ours at that instant
without appealing to its start time. Chain the fence from there instead, and
take that walk at the close boundary while the root certainly still lives: the
root may leave inside the grace window, and the post-timeout refresh never runs.

A row absent from the later walk still keeps its earlier boundary, and a row no
walk has ever re-derived in a later second is still never escalated.

* Treat an absent managed-account list as empty, not as unreadable

An empty claudeManagedAccounts array and a missing one are the same answer:
this user has no managed Claude accounts, so nothing claims an identity and
ambient auth is the truth. Refusing on absence strands any profile that simply
never wrote the key, and it disagrees with the auth policy, whose own predicate
takes `(accounts ?? [])` for exactly this reason.

Only settings that cannot be READ stay unknown, and those still refuse — as do
a WSL-bound active account and a selection naming an account the list does not
explain.

The earlier reasoning treated a missing field as settings we failed to parse.
That conflated "not present" with "not readable"; only the second is unknown.

* Support structured Claude when accounts are registered but none is selected

Registered-but-deselected Claude accounts were refused, which is behaviourally
identical to having no accounts at all: the auth policy does not strip, ambient
auth is the truth, and the UI names no host identity. A user who deselected
their accounts silently got legacy chat with nothing explaining why.

Nothing selected for the host runtime is two states the settings cannot tell
apart after the fact, because pruneInvalidClaudeRuntimeSelection empties the
host slot and persists null in the second one:

  honest deselection      -> ambient auth, UI names nothing   -> SUPPORTED
  the WSL-only steady state -> ambient auth, UI names the WSL account -> REFUSED

The presence of any WSL-bound account in the list decides. Simplifying this to
"none active -> supported" re-opens the auth-identity misrepresentation, so the
tests fail loudly on exactly that: five of them, across the unit rule and the
createSupport path.

* Stop treating an unanswerable create-support probe as a refusal

A worktree is not resolvable for a beat after createWorktree resolves, so a
probe fired immediately after creation fails the RPC with selector_not_found
instead of answering. The catch collapsed that into `supported = false`, so the
composer refused and quietly built a terminal session — the gate never said no,
it was never asked successfully. Elapsed time was the only input that decided
whether a Claude launch went structured.

"Could not answer" and "answered no" are different states and only the second
is a verdict. Retry while the host cannot yet resolve the selector, with a
bounded backoff that covers the measured window with margin, and keep refusing
on the first ask for everything else. Fail-closed is unchanged: a probe that
still cannot be answered when the budget is spent refuses.

The retry is narrowed with the shared error-code matcher, which classifies a
token that transports re-wrap into a longer message without matching prose that
merely mentions it.

Codex never probes, so this race has never been able to refuse a Codex launch —
the race itself is identical for it. Recorded at the early return, because
whoever gives Codex a probe inherits the bug.

* fix(claude): fence the forced sweep on re-derivation, not on lstart's second

A descendant forked in the same wall-clock second as every walk that sees it was
signalled with SIGTERM and then never escalated, so a SIGTERM-resistant child
survived tab close, app quit and a full relaunch. Two children of one parent
96ms apart across a second boundary took opposite paths. The leak predates this
branch: it reproduces with the change reverted.

`ps lstart` has one-second resolution, so a walk landing inside a row's birth
second can never rule out a pid recycled later in that same second. But a walk
is not a match: a ppid walk only reaches what the root actually parents, and the
root is pinned by Node's own handle, so a row the walk re-derived is ours
whatever second it was born in -- a stranger would have to have been forked into
our tree, and then it is not a stranger. Fence the escalation on that.

Rows a merge retained from an earlier walk are not re-derived and still answer
to the start-time fence, which remains correct for them.

Scoped to callers that revalidate identity before signalling, which is the
Claude close path. Codex teardown reaches this same verifier and is unchanged;
the argument holds there too, but widening it is its own deliberate change.

Also reverts two changes from the previous attempt at this leak. Advancing the
capture boundary on a later walk is inert once the sweep fences on re-derivation
-- both key on the same set of rows, so the new term short-circuits for exactly
the rows whose boundary it advanced. The extra ladder refresh was a duplicate
full process-table read: close() already awaits tree.refresh() immediately
before proveClaudeChildExit, on the only path that reaches it.

Known property: the kill lands roughly a grace window after the walk that proved
membership, so a pid recycled inside that gap could in principle be signalled.
It is bounded -- matchingSnapshotRows already requires the live row to carry the
same start-second and pgid, so an impostor must be born in the remainder of that
one second, land on that exact pid, and sit in the same process group, and it
has already received the unfenced SIGTERM from the same loop.

* Run the Claude structured integration suite as a runtime client

The suite exercises agentSession.* for Claude, not the mobile surface: nothing
in it asserts anything mobile-specific and its sibling integration suites use
'runtime'. Mobile now additionally requires the experimental structured-chat
setting, which structured-agent-session.test.ts pins in both states, so the
stale 'mobile' fixture was claiming coverage it never had.

* fix(claude): report effort from get_settings, which is the only frame that has it

The composer's Effort pill rendered blank in every structured session. This is
not a missing source: the publication reads `effortLevel` off the `system/init`
frame, and that frame has never carried an effort of any kind, while the correct
value is already fetched at acquisition and thrown away on the auth diagnostic.
Verified two ways -- a live get_settings probe against Claude Code 2.1.258, and
the shipped binary's own init frame construction, which lists `model` and no
effort. So `reportedOptions.effort` was always empty, the options reader dropped
the key, and the pill had no value. Model survived only because
`currentModelId()` has a fallback chain.

The get_settings call acquisition already makes reports the session's current
effort as `effective.effortLevel`; pass that into the publication instead.
Selecting an effort already worked, so this is the arrival value only.

The legacy PTY path is unaffected and must not be "fixed" to match: it reads its
effort by parsing the startup banner (`CLAUDE_MODEL_EFFORT` in
src/renderer/src/components/native-chat/claude-terminal-session-options.ts),
which is why it shows a value where the structured path does not.

Also removes the fixture that hid this: the fake init frame invented
`effortLevel: 'high'`, a field the CLI does not send, which is why every gate
stayed green over a value that is always empty in production. The fixture's
get_settings now returns the real {applied, effective, sources} shape instead of
a bare `{env: {}}`, so the two adapter tests that asserted an effort keep
asserting it through the path production actually uses.

The reader returns null rather than defaulting: an effort nothing measured would
repeat the fixture's mistake, and a blank pill is the honest degradation if the
provider ever renames the key.

* fix(claude): only record an effort the child confirms it adopted

apply_flag_settings answers `success` for an effort it then ignores. Measured
against Claude Code 2.1.258: applying `bogus-effort-xyz` returns
subtype "success" with no error while `applied.effort` stays at its previous
value, and a valid `low` moves it. The option write treated the absence of a
throw as adoption and recorded the requested value unconditionally, so Orca
would show and persist an effort the child was not using, with nothing anywhere
reporting a problem.

Read the effort back after applying it, through the same reader the arrival
value uses, and reject when the child reports a different one. A readback that
could not be taken is not evidence of a refusal -- the apply itself succeeded --
so it still records; only a readback that disagrees rejects.

Not reachable from today's picker, which offers catalog values only, but the
CLI's effort catalog is server-delivered and has changed before, so a retired id
would otherwise become a pill confidently displaying a setting that never took.

* test(claude): assert the effort contract against the real binary

The blank pill survived every gate because the only tests that touched it were
fixture-backed, and the fixture invented the field. A test that pins the shape
we read cannot catch the provider renaming the key, which is the failure mode
that produced this defect.

Asserts both halves against a live authenticated CLI: that no frame it publishes
carries an effort at all, and that the session's current effort arrives through
get_settings. Which frame proves the session varies by host -- this machine
proves it with a SessionStart hook rather than a system/init frame -- so the
negative half asserts over every published frame rather than picking one.

Skips with the rest of the file when no authenticated CLI is present.

* fix(claude): stop the synthesised content-part kinds leaking into the transcript

Sending an image put a bare `claude · message:user:content:image` row between
the user's bubble and the answer. Two causes, and only the second is a family.

An image part counted as modelled only when `source.type === 'url'`, but
claudeDispatchMessageContent sends a local attachment as a base64 source and the
CLI replays that shape back, so every attached image was classified unmodelled.
Accept the base64 and file sources Orca itself sends.

The family is the real defect. `message:<role>:content:<type>` kinds are
synthesised at runtime from whatever `part.type` arrives, so unlike the
top-level frame catalogue they can never be enumerated ahead of time -- the
`?? 'timeline-substantive'` default then prints the synthesised name at a user
who cannot act on it. That default is right for top-level frames, where
"substantive" means show the frame; here it meant show our own vocabulary, which
drops the content AND leaks the opcode.

So an unrenderable part now renders a sentence saying exactly that, with the
kind and payload still on the row's disclosure. A part that carries its own
readable sentence keeps it -- the placeholder is a fallback, not an override.

An unknown future part type is therefore visible, never silently dropped and
never printed as a kind: the same principle as the effort readback, which
records only what the provider confirms.

* Declare agentSession.requestHandoff on the cross-version wire surface

The manifest is a ratchet for cross-version reachability, so the method is
declared with real HandoffParams rather than counted. requestHandoff is
capability-gated through requireStructuredHost and has no client caller, so
declaring it is the whole of the change.

Also model two host capabilities the harness omitted: the stub host's
supportsCreate, and the fake adapter's, without which adapterSupportsCreate
falls through to a supportsLocation the fake also lacks. Every ensure was
refused for the harness's silence rather than for its location.

* Gate structured Claude session tabs on the client capability that names them

The Claude structured lane deleted the projection's `agent !== 'codex'`
filter and added CLAUDE_STRUCTURED_AGENT_SESSION_RUNTIME_CAPABILITY in the
same commit, but never wired the constant to anything. Paired clients then
received agent-session tabs for Claude, which no shipped client renders --
mobile's resolveMobileNativeChat returns null for every agent but codex, so
the row listed and selected into a pane with neither chat nor terminal.

Restore the filter behind the declared capability instead of the bare agent
name. No client advertises it yet, so this matches main's behaviour today
and becomes a negotiation a future client can opt into.

* Confirm the structured Claude model against the model the CLI reports

set_model answers success for any string, including a model it cannot
resolve — the failure only surfaces when the turn runs — and get_settings
reports the settings-file model, not the session's. The init frame that
opens each turn is the only channel carrying the adopted model, so keep
the session's reported model current from it instead of reading it once
at acquisition.

Also stop rejecting an effort the readback cannot represent: max is
session-scoped and excluded from the persisted effortLevel, so a readback
reporting the level underneath it is an absence of evidence, not a refusal.

* Clear the session-option hedge when the provider confirms the value

The pill claimed every option was unconfirmed for the life of the session:
the renderer recorded each write as dispatched and nothing ever moved it,
so a model the CLI had already reported back still read as unconfirmed.

Carry the provider's own confirmation to the surface. Main reports which
option ids the provider named rather than merely accepted, and the client
re-reads options as a turn changes, because the frame that opens a turn is
where the adopted model arrives. A value the provider has not reported
stays hedged, including an effort whose readback could not be taken.

The confirmed list is optional on the wire: a host that predates it sends
nothing and the client keeps hedging, which is the behaviour it had.

* Keep the model report current across an acquisition fence bump

* Show the picked session-option value and let the provider report correct it

The pill showed a "not confirmed" second tooltip line for any value we had sent
but not yet seen reported back. Nothing acts on it, and for the PTY lane it was
permanent — that transport has no report channel. The pill now shows the picked
value immediately and the provider's per-turn report corrects it when the two
disagree; a newer local write still outranks a report that precedes it.

`dispatched` stays as a provenance member rather than collapsing into `applied`:
it is produced independently by the PTY lane, and it is where the `confirmed`
wire field lands, which would otherwise be unobservable.

Effort keeps its readback and its rejection path. That matters more now, not
less: with the hedge gone the rejection is the only user-visible failure signal
on this surface, so a spurious one would be the loudest bug here. Skipping the
readback for an effort the settings response structurally cannot echo is what
prevents it — the response carries the persisted level, so reading it back for a
session-scoped value would report the level underneath and fail a valid write.

* Hedge a session-option value only when the terminal transport sent it

Both lanes emit `dispatched`, so it could never say which one produced a value.
The descriptor now carries the transport that built it, set once in the shared
snapshot builder from a parameter that is required rather than defaulted — the
builder is the only place a descriptor is constructed, so a new producer has to
name its lane or fail to compile.

The structured lane confirms every value from the provider's own per-turn report,
which makes the hedge transient noise there. The terminal lane can only learn an
outcome by parsing the screen back, and only for Claude: every other agent's
`dispatched` value stays unconfirmed for the life of the session, so the line is
the only signal that we sent something we never saw land.

* Refuse an effort the session's model advertises no control for

* Refuse tab mutations on a Claude row the client never negotiated

The branch added a case asserting a client advertising only
agent-session.structured.v1 may mutate a claude row. That is the same
ungated behaviour the projection gate removes, encoded a second time —
mutation authorization reads the projection, so hiding the row refuses
the write. Assert that contract instead, and add the positive case for a
client that does negotiate Claude rows.

* Resolve the Claude session's current model in one place so the effort guard and the pill agree

* Record an effort the child did not adopt instead of refusing the write

apply_flag_settings answers success for an effort it then ignores, so the
readback exists to detect that. Refusing on it made the detection a veto,
and a veto is only correct if the readback can never be wrong about which
model is current -- which it was, twice. The pre-flight guard already
refuses a level the model advertises no control for, so the veto guarded a
door that is now locked upstream.

Keep the detection, drop the refusal: a disagreement records the child's
own answer and omits the option from confirmed, so main stops vouching for
a value the provider rejected without blocking the user's write.

* Stop a slow whole-machine ps from being read as an absent process

`ps -axo ...command=` pays a per-pid argv read: measured 1.15s for 1,948
processes (0.03s without `command=`), and CPU contention stretched the same
capture to 6.0s. Two budgets sized for a cheap look then misreport a readable
machine.

The reader's 3s ceiling killed 6 of 20 consecutive captures at load 27, so
every consumer answered "unverifiable" about a table it could read. Raise it
to 15s, and stamp the capture instant at ps START so `capturedAgeMs` is the
upper bound its contract promises -- a 6s capture used to report itself as
freshly taken, understating staleness against a 5s kill gate. The TTL keys on
completion so a slow capture still coalesces instead of forking ps per caller.

`readStructuredTuiProcessIdentity` then spent its whole 5s wait inside one
capture and concluded "no exact child" after a single look taken before the
child existed (observed landing at ~3.5s). Absence needs a look that did not
race the spawn, so require two captures before the deadline can end the loop.

Both surfaced by the real-binary Claude TUI resume test, which failed ~1 in 5
under load; 14/14 now, 8 of those runs containing a capture the old 3s budget
would have killed.

* Let the desktop renderer negotiate Claude structured tabs

The paired-client gate hides agent-session rows an agent the client cannot
render. The desktop renderer's own IPC dispatches as clientKind 'runtime'
advertising only agent-session.structured.v1, so the gate hid Claude rows
from the surface this feature ships on. It renders them; it should say so.

* Stop a slow process table from silently blinding every freshness gate

Stamping `capturedAgeMs` at ps START made the number honest, and honest broke
both consumers that read it. `ps -axo ...command=` measured 2.5-9.0s on an idle
2,002-process laptop and 4.0-18.6s at load 46, so the age it now reports lands
past every budget: `planRelayPtySweep` refuses the stop as "too old", and the
renderer's `admitRemoteForegroundEvidence` refuses the record outright. That
second one is the expensive half and was outside the diff -- a refusal bumps
`consecutiveInspectionErrors`, the poll scheduler backs off to its 10s floor,
and agent-completion detection stops for the pane. The subsystem went blind on
exactly the loaded hosts the honest stamp was meant to serve.

The evidence-publishing read now gives up at 1,200ms instead of waiting out
`PS_TIMEOUT_MS`. It is one budget for one question: these consumers ask whether
an observation describes NOW, and past this it does not -- a late answer is
refused by the age gate anyway, having first blocked a polled path for the whole
capture, so a prompt `unverifiable` is both the truthful verdict and the cheap
one. Both relay call sites already produce it from a rejection, and an admitted
`unverifiable` costs a poll where a refusal costs the cadence. Identity proof
keeps the full 15s through `getFreshProcessTableSnapshot`, because it asks
whether a process EXISTS and must never read slow as absent. The budget bounds
the wait, never the capture: the reader coalesces, so an abandoned wait leaves
its capture running to fill the cache rather than forking a second whole-machine
`ps` on the host that can least afford one.

1,200ms is bracketed rather than picked. The floor is the capture's own cost --
`command=` measured 1.15s for 1,948 processes on an idle host, and a budget
under that answers `unverifiable` about a machine nobody is straining. The
ceiling is the consumer's: 2,000ms, less the 500ms a TTL-shared capture may
already have aged, leaves 1,500ms, and transit takes the rest.

That ceiling only fits once the capture stops being charged twice. `ps` runs
inside the RPC round trip, so its duration is already in `receiveDelay`, and
`capturedAgeMs` is that same duration on the host's clock; summing them halved
the budget this gate grants a host from ~2.0s of `ps` to ~1.0s, which is why a
1.2s capture arriving at 1.3s read as 2.5s old and was refused. Admission now
takes the larger of the two. The sweep's gate keeps its sum, which is correct
there: `evidenceAgeSinceListingMs` is stamped after the listing ARRIVES, so it
measures planning time and overlaps nothing.

A stated limit rather than an assumed one: 15s is not proven sufficient for
identity proof. The same capture reached 18.6s at load 46, so that path can
still time out and answer "no exact child" about a host it simply could not read
in time. Narrowing it needs a cheaper question than a whole-machine argv read,
not a larger number.

The one test guarding this field could not fail. `beginPtyHandlerTest` installs
fake timers, so `Date.now()` is frozen, the real reader reports exactly +0, and
`0 <= 500` held identically for a hardcoded zero, for completion-stamping and
for start-stamping -- while the real reader on that host returns thousands of
ms. It now drives a measured age in and asserts the handler publishes it rather
than restamping; that the reader MEASURES it correctly stays pinned separately,
against a controllable clock. Both consumers get boundary coverage either side,
and each new gate was ablated red before it went green.

* Keep the compatibility fields off the capture the budget just abandoned

inspectProcess falls back to processHasChildren and listProcesses to
getForegroundProcessName, and both read the same TTL-shared capture with
no budget of their own. On a slow host they joined the in-flight capture
the budgeted evidence read had just given up on, so the call still blocked
for the full 6-18s and the budget bought nothing -- once for inspectProcess
and once per managed PTY for listProcesses.

Use the degraded answers those helpers already give for an unreadable
table, reached promptly. pty.hasChildProcesses keeps its unbudgeted fresh
probe: it is a one-shot destructive gate that can afford to wait.
