Orca can already build a searchable index of your agent transcripts, but nothing on your
computer ever turned it on. This PR adds the switch and the plumbing behind it. The switch
is off, and there is no UI for it yet, so on a normal install nothing changes: the search
endpoints now say "off" instead of "this computer doesn't do that".

What Changed

Settings. src/shared/ai-vault-search-settings.ts holds { enabled, historyDays },
off by default, plus normalization and a Zod schema. GlobalSettings.aiVaultSearch persists
it through the settings IPC like any other field. There is no paused: the PR 3 indexer is
immutable, so every change is close-and-construct.

One instance per host. SessionSearchInstance holds at most one indexer + engine pair
and the three recipes: a settings change closes the pair and constructs a new one, disabling
closes with no replacement, clearing closes, removes the database and constructs again. The
database lives beside the scanner's parse cache, one file per host.

The scanner child owns it (desktop). The transcript reader runs in that child, so the
index consumer does too. Three new request operations (searchSessions, searchStatus,
searchReconcile) and one fire-and-forget settings message; main never opens the file. The
init frame became a factory so a respawned child reads current consent, and idle retirement
is suppressed while the index is on, because an indexing child is never idle from out here.

Registration on all three hosts. Desktop main forwards to the child. orcad and the SSH
relay daemon have no scanner child, so on those the instance lives in the process itself.
See "Deviations" below.

Measured. A committed benchmark prices a warm pass on 5,000 transcripts.

Why

Nothing constructs an indexer in production before this PR, so the search endpoints PR 5
shipped answer no-service on every host. no-service means "this host does not have the
feature", which is a different thing from "the index is off" and is what a client shows an
old host. Registering the service is what makes the second answer possible.

Deviations from the plan, and why

The relay and orcad do not use a scanner-service child, because they do not have one.
The plan says the scanner child owns the database on every host. That holds for the desktop.
It cannot hold for the other two:

  • config/scripts/build-orcad.mjs emits only the watcher and daemon children beside
    orcad.js. getAiVaultServiceEntryPath() resolves to a path no orcad deployment contains,
    so a child-backed service there would be registered and permanently broken.
  • The relay's AI Vault sidecar is a different entry and protocol
    (src/relay/ai-vault-service-entry.ts). It runs scanRemoteAiVaultSessions through a
    filesystem provider and publishes nothing to the transcript channel the index consumes.

On both, the process that would drive the index's own reads is the daemon itself, and it is
the only writer, so the two-process rebuild race the desktop rule avoids cannot arise. Both
are gated on node:sqlite: orcad's build comment states a deliberate Node 18 floor and the
relay is built target: node18, and node:sqlite needs 22.5. A host without it registers
nothing, which is the truthful no-service.

The relay registers with consent permanently off. Consent lives in GlobalSettings,
which the relay daemon does not read, and nothing carries a setting to a remote host yet.
Registering it anyway is still worth it: it is what lets a client tell "off" from "too old".
Turning it on needs a wire change and belongs with the UI.

No protocol operation for clear. SessionSearchInstance.clear() exists and is tested,
but nothing in this PR sends one, so no operation carries it. PR 8 owns the caller.

Three files hit the max-lines ceiling and were split rather than disabled around: the
invalidation deadline moved into the class that owns invalidations, call cancellation and
the start requeue into the call-state module, and orcad's flag parsing into its own file.

Visual Proof

N/A: no UI. This PR adds no renderer code and no user-visible surface; the setting has no
control until PR 8.

Testing

Measured on this machine (Apple silicon, macOS), synthetic 5,000-transcript / 87 MB tree
under 40 project directories, three runs:

run 1 run 2 run 3
cold build 4906 ms 4421 ms 4098 ms
warm full sweep 95 ms 148 ms 88 ms
warm cycle 86 ms 143 ms 75 ms

This is the number the 20 s reconcile interval should be revisited against. This PR does not
tune it.

Gates, all exit 0:

pnpm tc
pnpm test src/main/ai-vault-search src/main/ai-vault src/main/ipc src/relay src/main/orcad src/shared
pnpm run check:code-quality:changed
pnpm run check:react-doctor:changed
pnpm run audit:code-quality:type-aware
pnpm exec vitest run --config config/vitest.config.ts tests/e2e/cross-version-wire
pnpm run build:orcad
pnpm run build:relay

1415 test files, 14605 tests. The cross-version wire suite is 49 tests. Both bundle builds
were run because this change reaches the orcad and relay module graphs; build-orcad
re-confirms zero node:sqlite and zero electron imports in that bundle.

New coverage: the child booted over the real protocol with no renderer, reporting phase and
a live generation after one indexed transcript and answering search and reconcile; the
instance across off, on, narrow, widen, disable and clear; the main-side forwarder including
child-not-ready mapping; per-host registration; the client's index hold and per-spawn init;
settings normalization and the change hook.

Tested on macOS only. Linux, Windows, a live SSH relay and a real orcad deployment were not
exercised. No real transcript tree was read: every test uses a temp fixture root.

AI Disclosure

Review

Agent skill upstream boundary

  • Not applicable, or this change follows docs/reference/agent-skill-sharing-upstream-boundary.md and copies or mechanically translates no upstream skill-installer source, tests, fixtures, registry entries, path tables, comments, or documentation.

Notes

  • Security. Off by default; nothing reads a transcript until consent is recorded. The
    index stores transcript content as written (decided 2026-09-09), under the same user-only
    data root as the parse cache. Disabling does not delete it, which PR 8's consent copy has
    to state.
  • Cross-platform. All paths through path.join. No platform-conditional behavior added.
    Only macOS was exercised.
  • Remote SSH. The relay registers a service that is off and cannot be turned on; the SSH
    leg's answer changes from no-service to disabled on a relay whose Node has
    node:sqlite, and stays no-service otherwise. No wire change: the scanner-service
    protocol is main-to-child on one machine.
  • Mobile. No change; mobile reads the same status endpoint through the runtime RPC.
  • Backwards compatibility. A profile with no aiVaultSearch key reads as off. The
    scanner-service protocol version is unchanged because both halves ship in one binary.
  • Performance. Nothing runs on a default install. With the index on, a warm pass costs
    the numbers above and the scanner child stops being retired after ten idle minutes.

Checklist

  • This PR is small and focused
  • I explained what changed and why (including ELI5)
  • Before/after screenshots or videos attached for UI changes, or N/A with reason
  • Self-reviewed for correctness, security, and performance
  • Cross-platform, SSH/remote, and path/shortcut impact considered (or N/A)

Important

One correctness gap in the child's settings path: a live indexer never picks up re-resolved scan roots. pushSessionSearchPolicy re-resolves them so "a distro started since boot must be in the new window", but SessionScannerServiceSearch.apply discards init.roots whenever an instance already exists. Details inline.

Reviewed changes

  • Settings + consent model. New off-by-default GlobalSettings.aiVaultSearch = { enabled, historyDays } with normalization (floor, clamp 3650, non-positive/NaN → null), a Zod schema and an equality helper (src/shared/ai-vault-search-settings.ts); persisted through the settings IPC, with the write hook in src/main/ipc/settings.ts.
  • One live pair per host. SessionSearchInstance holds at most one {indexer, engine, db} and implements close-and-construct for apply/disable/clear (session-search-instance.ts); retention cutoff is refreshed per search against the shared engine options object.
  • Scanner child owns the desktop index. Three new protocol operations (searchSessions/searchStatus/searchReconcile) plus a fire-and-forget sessionSearch message; init became a factory re-read on every spawn; idle retirement is suppressed while the index is on (session-search-child-service.ts, session-scanner-service-*.ts).
  • In-process registration for orcad and the relay. installInProcessSessionSearchService runs the instance in the daemon when there is no scanner child, gated on node:sqlite (session-search-in-process-service.ts, orcad-session-search.ts, relay-runtime-services.ts).
  • Scan-root extraction. localAiVaultScanRoots() was factored out of listAiVaultSessions and is shared by the list and the index (cached-session-list.ts).
  • Benchmark. A committed warm-pass benchmark over a synthetic 5,000-transcript corpus (config/scripts/session-search-pass-benchmark.ts).

ℹ️ Index database is created with weaker file permissions than the parse cache it sits beside

The index deliberately stores transcript content as written and unredacted (session-search-schema.ts), while the parse cache in the same <dataRoot>/ai-vault/ directory is written with PRIVATE_DIRECTORY_MODE = 0o700 and PRIVATE_FILE_MODE = 0o600 precisely because "the payload contains transcript-derived preview text; keep it user-only". openSessionSearchDatabase creates the directory with the platform default mode and lets SQLite create the .sqlite/-wal/-shm files with its default mode, so the index copies of transcript text can be more readable than the parse cache. This PR is the first that actually creates the file, so it is worth deciding whether the index should adopt the same 0o700/0o600 treatment or whether the userData root is trusted to already be user-only on every platform.

Technical details
# Index file permissions

## Affected sites
- `src/main/ai-vault-search/session-search-schema.ts` (`openSessionSearchDatabase`, `mkdirSync(dirname(path), { recursive: true })`) — no `mode`; SQLite's default file mode applies.
- `src/main/ai-vault/session-parse-cache-persistence.ts` (`persistSnapshot`, `PRIVATE_DIRECTORY_MODE`/`PRIVATE_FILE_MODE`) — the hardening the index lacks.

## Required outcome
- The index files should be user-only on POSIX, matching the parse cache's stated policy, or the PR body should record why the shared data root already guarantees it.

## Open questions for the human
- Is `getCanonicalUserDataPath()` guaranteed `0o700` on Linux/Windows, or is the parse cache's per-file hardening the only guarantee?

ℹ️ A child that faults while the index is enabled stays dead until some later request

AiVaultServiceSessionSearchHold stops idle retirement while consent is on, but it does not cause a respawn: a child error/exit reaches onFault, which schedules restartPolicy.recordFault(() => this.pump()), and pump() only calls ensureChild() inside the per-lane loop over queued calls. With an empty queue the timer fires into a no-op, so indexing stops until a later searchSessions/searchStatus request (or invalidate) happens to spawn a child. The class doc already notes indexing resumes on "some later scan", so this may be intended — flagging it because the hold's stated purpose is to keep the index alive, and no test faults the child while idle.

Technical details
# Idle fault leaves no scanner child

## Affected sites
- `src/main/ai-vault/session-scanner-service-client.ts` — `onFault` (schedules `pump`), `pump` (only `ensureChild()` with a queued call), `updateSessionSearch` (the only enabled-path spawn).
- `src/main/ai-vault/session-scanner-service-client-state.ts` — `AiVaultServiceSessionSearchHold.record` sets the flag but spawns nothing.

## Required outcome
- Either a fault while `holdsChild` should re-arm `ensureChild()` after the restart delay, or a comment/test should pin that recovery is deliberately request-driven.

## Open questions for the human
- Should the hold, like `updateSessionSearch`, own crash recovery for the index, or is lazy respawn acceptable because any status poll revives the child?

…tion

Two booleans and nothing else: `enabled` and `historyDays`, off by default
because building the index reads every transcript on the machine. No `paused` --
the PR 3 indexer is immutable, so every change is close-and-construct.

The settings IPC normalizes a write like every other field and hands the change
to the index; there is no UI for it until PR 8.
The object that owns a host's live index and the three recipes that change it.
The indexer is immutable, so a settings change is close-and-construct, disabling
is close with no replacement, and clearing is close, remove the database,
construct. The new instance's first sweep purges a narrowed window and admits a
widened one, so neither needs a code path.

The database sits beside the scanner's parse cache, one file per host. A runtime
with no node:sqlite can hold no index at all, which the Node 18 floor on orcad
and the relay makes a real case rather than a hypothetical one.
The transcript reader runs in that child, so the index consumer has to as well:
one read serves both the session list and the index. Three request operations
(search, status, reconcile) and one fire-and-forget settings message carry
everything a parent needs; main never opens the database file.

The init frame becomes a factory because it is read at every spawn, so a
respawned child sees current consent rather than the first frame's. A child
holding a running index is never idle from the parent's side, so idle retirement
is suppressed while the index is on -- retiring it would stop the reconcile loop
until some later scan happened to respawn one.

Both files this lands in were already at the max-lines ceiling, so three
collaborators move to where they belong rather than being disabled around: the
invalidation deadline into the class that owns invalidations, call cancellation
and the start requeue into the call-state module, and orcad's flag parsing into
its own file.
…nswers

Without a registered service a host answers no-service, which means "this host
does not have the feature" rather than "the index is off". All three hosts now
answer the second thing.

The desktop forwards to the scanner child. orcad and the SSH relay daemon have
no such child -- orcad ships only the watcher and daemon entries, and the relay's
AI Vault sidecar runs the remote scanner, which publishes nothing to the
transcript channel -- so on those two the index lives in the process that would
drive its reads, gated on a runtime that has node:sqlite at all.

The relay registers with consent off and no way to turn it on: nothing carries a
setting to a remote host yet. That is the honest state, and it is still worth
registering, because it is what tells a client the difference between off and
too old.
The number the reconcile interval will be revisited against, measured rather
than argued: a warm sweep stats every file under every root, a warm cycle stats
the newest N per agent, and neither reads what the index already holds. It does
not tune the interval.
main's new type-assertion rule reaches every file this branch touches. All nine
sites drop the cast rather than carry a SAFETY: rationale: the operation guard
narrows with `in`, the sqlite probe narrows the builtin it loads, the child test
keeps the discriminated reply instead of widening it, and the settings resolver
takes `unknown` -- which is what it really reads, since a persisted profile can
hold a value no version of this code wrote.

Rebased onto main, base retargeted

PR 5 (#20277) merged, so this branch now sits directly on main at 4eea86fa9a (six commits, clean rebase, no conflicts). The base was retargeted from session-search-pr5-contract to main.

Gate pass on the pushed head, all green:

Gate Result
pnpm tc pass
pnpm test (ai-vault-search, ai-vault, settings, ipc, orcad, relay) 731 files, 6,893 tests pass
check:code-quality:changed pass
check:react-doctor:changed pass
audit:code-quality:type-aware pass
cross-version wire suite pass
build:orcad, build:relay, build:cli pass

Still inert on default installs: the setting is off and there is no UI to flip it, so every search endpoint answers unavailable/disabled instead of no-service.

Follow-ups recorded in the plan doc, not in this PR:

  • orcad runs the index in-process with synchronous SQLite writes; move it to a child if servers start enabling search.
  • The relay registers with consent permanently off; carrying the setting to a remote host is a wire change that belongs with the UI.

📝 Walkthrough

Walkthrough

The pull request adds opt-in AI Vault session search with normalized retention settings and a SQLite index. It adds session-search instances, scanner child protocol operations, in-process services, and host registration for desktop, Orcad, and relay. Settings changes update the index without unnecessary restarts. The change also updates scanner child lifecycle handling, extracts Orcad argument parsing, adds tests across the new paths, and adds a 5,000-session benchmark.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to db397

The parent re-resolves scan roots before every policy push, precisely so a
WSL distro or extra Codex home that appeared since the child spawned enters
the window. The child forwarded only the settings to a live instance and used
the roots solely in its `??=` initializer, so those roots were dropped for the
child's lifetime.

The indexer stays immutable: a structurally different root set closes the pair
and constructs a new one, the same way a changed databasePath already does.
Compare via `sameSessionSearchRoots` rather than a plain JSON compare, because
nothing fixes the key order two producers write; lists are sorted too, since
the indexer walks every root and a re-enumeration that reorders is not a
change. An unchanged set still never restarts a running index.

The orcad and relay in-process hosts resolve roots once at install and never
re-apply, so they have no such seam.

Delta since the prior pullfrog review (66603554bf): commit c84c9c42ba fixes the one outstanding correctness thread, with no other changes to the branch.

  • Refreshed scan roots reach a live index. SessionScannerServiceSearch.apply now records the pushed roots and closes/rebuilds the pair when they differ structurally, instead of discarding them once an instance already exists (src/main/ai-vault/session-scanner-service-search.ts:43).
  • Structural roots comparison. New sameSessionSearchRoots compares key-sorted fields with list-sorted arrays and treats an absent key as equal to an explicit undefined, so a re-resolved root set that names the same trees stays a no-op (src/main/ai-vault-search/session-search-scan-roots.ts:146).
  • Coverage. session-scanner-service-search-roots.test.ts proves a root added after the child spawned becomes searchable and an identical set does not close the pair; unit tests pin the comparator's order/absence behavior. Focused run: 6/6 pass.

Three review items.

The hold keeps a child alive for the index, but only a queued call ever
started one: `pump()` skipped a hold with an empty queue, so an idle indexing
child that crashed, or an `ensureChild()` that failed at start, left indexing
stopped until an unrelated request happened to arrive. `pump()` now starts the
child the hold requires, which is also the restart callback the fault policy
already schedules, so the existing delay and circuit bound the retry exactly as
they bound a queued call's start. `updateSessionSearch` goes through the same
seam instead of its own `ensureChild` call.

A search registers no AbortController, so a cancel sent for a search id was
added to the `cancelled` set and never consumed. Nothing can reach that today
-- no caller passes a signal and the child answers in milliseconds -- so this
is only a leak of ids: consume it when the search settles.

The orcad argument doc claimed a `--`-prefixed value stays a flag. The parser
takes the next token regardless, and orcad-launch-contract.test.ts pins that,
so the doc is what was wrong. Behaviour is unchanged.

Reviewed changes

Delta since the prior pullfrog review (c84c9c42ba): commit 9885a731ef gives the index hold its own child restart and clears a cancellation-id leak.

  • Hold-owned child restart. AiVaultScannerServiceClient gains startSessionSearchChild() and calls it from updateSessionSearch and the tail of pump(). onFault's recordFault(() => this.pump()) now respawns an idle indexing child after the existing 250 ms/1 s/5 s backoff, so a crash while the hold is on no longer leaves indexing stopped until an unrelated request arrives. The guard (disposed || !holdsChild || child || readyWaiter) keeps it from racing a spawn already in flight for a queued call.
  • Search cancel ids no longer accumulate. session-scanner-service-entry.ts deletes request.id from cancelled in a finally around the search execution, since a search registers no AbortController for anything else to consume the id.
  • orcad flag doc corrected. orcad-command-arguments.ts now documents that a value-taking flag consumes the next token literally (--bind --json binds --json), matching what orcad-launch-contract.test.ts pins. No behavior change.
  • Coverage. New tests fault an idle child with the index on (asserts a respawn at 250 ms carrying current consent) and off (asserts no respawn), and existing client tests were updated to the new init factory. Focused run: session-scanner-service-client.test.ts 18/18 and session-scanner-service-search-roots.test.ts 2/2 pass.

Delta since the prior pullfrog review (9885a731ef): commit f0323b1 adds desktop-only periodic scan-root refresh and makes the held child's restart wait out the restart circuit. The prior idle-fault concern is now addressed end to end.

  • Periodic scan-root refresh on desktop. installChildSessionSearchService owns a 5-minute unref'd interval that re-resolves localAiVaultScanRoots() and pushes the init only when the root set changed structurally (session-search-enablement.ts). The timer starts on enable, is cleared on disable, and the returned disposer aborts an in-flight refresh so a late resolution cannot push after shutdown.
  • Restart waits out the circuit. AiVaultServiceRestartPolicy.recordFault now schedules the restart at Math.max(delay, circuitUntil - now), so a child faulting while the index holds it is respawned once the circuit expires rather than firing a restart the open circuit would reject and then leaving nothing to retry (session-scanner-service-restart-policy.ts).
  • Disposal wired at quit. registerCoreHandlers installs the desktop service beside the AI Vault handlers and disposes it on will-quit.
  • Coverage. New tests pin periodic refresh only-on-change, enable/disable timer lifecycle, abort-on-dispose, restart waits out the circuit (and dispose cancels it), and each host's boot path reaching an installer. Focused run: session-search-host-registration.test.ts 10/10 and session-scanner-service-client.test.ts 20/20 pass.

Delta since the prior pullfrog review (f0323b1): commit db397e5 is a small refinement to the desktop root-refresh wiring plus a test-mock fix.

  • Policy reads deferred into the push. updateRootRefreshTimer now takes an explicit enabled argument and is called inside pushSessionSearchPolicy from the freshly read init frame (init.settings.enabled), instead of re-reading sessionSearchPolicy() from the install and settings-change paths (session-search-enablement.ts). The timer lifecycle is unchanged: starts when enabled, cleared when disabled, still driven by the same lastPushedRoots change gate.
  • AbortController replaced with a disposed flag. RootRefresh.controller becomes a plain boolean; the in-flight guard is still the post-await check, so disposal semantics are identical and one allocation per install is gone.
  • Test mock updated for the quit hook. register-core-handlers.test.ts's electron mock gains once, which the app.once('will-quit', …) wiring from f0323b1 requires. Focused run: host-registration 10/10, register-core-handlers 2/2, settings 35/35.

Codex review round + follow-up, head 705a35a5a2

A Codex reviewer went over the whole diff for correctness, YAGNI and simplification. Two findings held up and are fixed; the rest were rejected on inspection.

Finding Outcome
Three faults inside a minute open the restart circuit, but the restart timer fired at 5 s while the circuit stayed open for 60 s, so a held index never came back on its own Fixed in f0323b1542: the restart delay is now at least the remaining circuit time. Test covers cooldown and disposal.
Scan roots were re-resolved only on a settings change, so a WSL distro or Codex home that appeared after boot was never indexed Fixed in f0323b1542 + db397e5f16: a five-minute refresh while enabled pushes only when the roots changed, cleared on disable and on quit.
The refresh state carried an AbortController for one boolean and read settings eagerly at install Trimmed in db397e5f16.

705a35a5a2 then moved the service install from the desktop IPC registrar into the shared main-process runtime, so headless orca serve gets the same host-local service as the desktop; dropped the per-search retention-cutoff refresh so page cursors stay stable across pages (expiry rides the indexer purge, which already invalidates cursors); and short-circuits the root refresh when the setting is off.

Gate pass on 705a35a5a2, all green: pnpm tc; tests across ai-vault-search, ai-vault, shared, ipc, orcad, startup, relay (1,494 files, 15,351 tests); both changed-code gates; type-aware audit; cross-version wire suite; build:orcad; build:relay.

Still inert on default installs: the setting is off and there is no UI to flip it.

Delta since the prior pullfrog review (db397e5): commit 705a35a stabilizes pagination and moves host enablement to the shared boot path.

  • Retention window no longer refreshed per search. SessionSearchInstance drops refreshRetentionCutoff and the engineOptions/historyDays live-pair fields; the engine's retentionCutoffMs is fixed at construction (session-search-instance.ts:126). Pagination stays stable within a generation because the purge — which runs every pass, deletes expired files by files.mtime_ms, and bumps the index generation — also invalidates any cursor spanning it. The construction-time cutoff stays at or below the per-pass store cutoff, so the engine is never stricter than the purge and no stale rows outlive one. A new test crosses retention mid-pagination and still receives the next distinct hit at the same generation.
  • Disable applies without waiting on root discovery. pushSessionSearchPolicy reads the init frame up front and, when consent is off, clears the refresh timer and pushes the disabled policy immediately rather than first awaiting refreshSessionSearchScanRoots() (session-search-enablement.ts:103); a new test pins a disable landing while an enabled root scan is still pending.
  • Host install moved to the shared boot path. installChildSessionSearchService now runs in initializeMainProcessRuntime, which desktop and headless serve both reach, instead of the window-only registerCoreHandlers (main-process-runtime-service.ts:137). registerCoreHandlers is only invoked by main-window-core-services.ts, so no host loses the service and headless serve gains it; the host-registration test asserts the new location.

ℹ️ No critical issues — one design observation inline plus a stale-comment nit.

Reviewed changes

Delta since the prior pullfrog review (705a35a): commit 100d542 replaces the desktop's parent-side 5-minute scan-root poll with a child-initiated root request, and refreshes roots only on full sweeps.

  • Child-initiated root refresh. resolveRoots?: (signal) => Promise<roots> added to the indexer options; SessionSearchIndexer keeps a mutable this.roots, refreshed only on a full pass and reused by recent cycles (session-search-indexer.ts:279). A failed resolve rethrows, re-arms sweepNext, and deliberately does not sweep stale roots.
  • Request/response over the scanner-service protocol. New session-scanner-service-root-request.ts sends {type:'sessionSearchRoots', id} and awaits a matching answer; the parent answers in AiVaultScannerServiceClient.onMessage from a new resolveSessionSearchRoots option (= localAiVaultScanRoots), guarded by child identity and connected. Both message unions and isAiVaultServiceChildMessage gained the type.
  • Static init roots. session-search-service-init.ts no longer re-resolves; it emits roots:{executionHostId}. SessionScannerServiceSearch gains a constructor resolveRoots, and its sameSessionSearchRoots rebuild branch is now reachable only from callers that push real roots.
  • In-process hosts. orcad passes resolveRoots: localAiVaultScanRoots (roots resolved lazily on first full sweep); the relay still registers without one.
  • Reconcile semantics. createSessionSearchService.reconcile now requests { full: true }; sendAiVaultServiceCall extracted from the private sendCall; historyDays normalization deduped into the shared settings module.

ℹ️ Nitpicks

  • src/main/ai-vault/session-scanner-service-search.ts:47 — the comment still says "the parent re-resolves them on every push"; this commit removed that (sessionSearchServiceInit returns a constant host id), so the rebuild branch is now only meaningful for callers that pass real roots. Worth rewording so the next reader does not look for the deleted push.

SessionSearchService.reconcile is only reached from the registry's freshness: 'wait-until-current' path (reconcileWithin, 5 s budget), so mapping it to a full sweep now makes every fresh search kick off a whole-machine sweep plus an IPC round-trip for root discovery. Because the child runs searchReconcile and searchSessions on the same interactive lane, the search that follows queues behind that sweep. The pass deadline bounds it (~5 s) and warm sweeps are cheap, so this is not broken — but it does couple a client freshness hint to the heaviest pass. Worth confirming the coupling is intended, or noting that the indexer's scheduled sweep (every 15 cycles) already covers root refresh.

Technical details
# Freshness search now triggers a full sweep

## Affected sites
- `src/main/ai-vault-search/session-search-service.ts:24` — `reconcile` changed from `{ full: false }` to `{ full: true }`.
- `src/main/ai-vault-search/session-search-service-registry.ts:62-76` — `reconcileWithin` is the only caller; it races `reconcile()` against a 5 s timer on `freshness: 'wait-until-current'`.
- `src/main/ai-vault/session-scanner-service-search.ts:78-81` — `searchReconcile` awaits `instance.reconcile()` on the interactive lane that `searchSessions` shares, so the racing search still waits out the sweep.
- `src/main/ai-vault-search/session-search-indexer.ts:279-285` — the full sweep additionally awaits a parent IPC round-trip for root discovery.

## Required outcome
- Confirm a client freshness hint should own a whole-machine sweep, or give root refresh a lighter trigger (e.g. keep reconcile recent-only and rely on the scheduled sweep) so the freshness path does not depend on the heaviest pass.

* fix: gate startup agent recovery on host inventory

* fix: defer recovery while a live agent lacks conversation ownership

* fix(mobile): two known main bugs the RPC migration preserved (#20563)

* fix(mobile): two known main bugs the RPC migration preserved

A malformed host `error` and a null settings result both reach a property read that throws.
Both are deliberate behaviour changes; the goldens move in the follow-up commit.

`hostReplyErrorTextOrFallback` passed a truthy non-string through under a `string` annotation.
Its one caller is the in-band `git.commit` failure, and every consumer of that text is display or
prompt copy: `use-mobile-create-pr-runner` and `PrSidebarCreateEmptyState` record it as a commit
failure, `use-mobile-commit-failure-recovery` hands it to `summarizeCommitFailure`, which starts
with `raw.slice(...).replace(...)`. So no consumer needs the value, and the decision is the
fallback rather than `String(value)` — the relay handler declares
`commit(): Promise<{ success: boolean; error?: string }>`, so a non-string is a malformed reply,
and `generatedCommitMessageReader` in the same domain already reads a non-string host error as
absent. The parameter stays `unknown`, which it honestly is, and the `SAFETY` cast is gone.

`useNewWorkspaceRuntimeContext` read settings through `settingsRead`, whose reader preserves
main's `boxed!.settings` throw, so a `null` or absent result threw a TypeError out of the effect —
losing the trusted-hooks publish and the available-provider computation that follow it, not just
the settings. It now uses `optionalSettingsRead`, the operation that already reads a null or
absent result as absent settings, so the reply degrades exactly the way a reply with no `settings`
member does. Reply-side only: same method, same params, same barrier, no wire change.

* test(mobile): re-record the goldens the two bug fixes move

Baseline bumped to 3f71999237. Two goldens move an observation; the other 151 move only
`baseline` and `recorderSha256`, which `pilot-scenarios.json` is still digested into.

Observation moves, one claim each:

- `matrix-hostedreview.create-intent-git.commit-1`, partition `inner-false-object-error`:
  `settlements.run.value.error` and `state.outcome.error` go from `{"message":"inner refused"}` to
  `"Commit failed"`. A non-string in-band `git.commit` error is a malformed reply and now reads as
  the screen's copy, converging with `result-absent`, `result-null` and `outer-refused-no-message`,
  which already reported the fallback. The other ten partitions at this site are unchanged.
- `matrix-settings.workspace-context-settings.get-1`, partitions `result-null` and `result-absent`:
  the `unhandled-rejection` TypeError effect (`reading 'settings'`) is gone and `state.providers`
  goes from `[]` to `["github"]`. The effect no longer aborts the rest of the hook, so the
  provider computation runs; `state.settings` stays null because nothing was published, which is
  how a reply with no `settings` member already degraded. The other nine partitions are unchanged.

Header-only moves:

- 9 goldens of the `settings.workspace-context` family rename `namedDeltas` from
  `new-workspace-runtime-context-null-settings-typeerror` — the name now lies, the TypeError is
  fixed — to `new-workspace-runtime-context-null-settings-degrades-to-absent`.
- All 153 move `baseline` and `recorderSha256`. The digest covers `pilot-scenarios.json`, so the
  baseline bump and the rename re-digest every file.

No sender recording moved: both fixes are reply-side, and no golden's `sender` or `payloads` field
differs. The README paragraph that claimed the settings TypeError was preserved is updated, and
now records that the `ui.get` leg of the same hook still is.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): degrade a null ui.get result the way the settings leg now does

One host answers both legs of useNewWorkspaceRuntimeContext, so fixing only
settings.get left the likelier failure in place: a null or absent ui.get result
still threw `reading 'ui'` out of the effect, skipping the provider commit.

Review follow-ups on the same files: reply() returns the literal uncast and the
stub client is FakeSession, dropping two assertions and their SAFETY disables;
the degradation cases now assert absolute state instead of comparing mounts.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the goldens the ui.get leg fix moves

Observational move, 1 golden:

- matrix-settings.workspace-context-ui.get-1: the `result-absent` and
  `result-null` partitions drop their `reading 'ui'` unhandled-rejection effect
  and their state commits `providers: ["github"]` instead of `[]`, because the
  effect no longer throws before the provider commit.

Header-only moves, 153 goldens: `baseline` to the fix commit and `recorderSha256`,
which covers `pilot-scenarios.json` and so re-digests on the delta rename.

The delta is renamed `new-workspace-runtime-context-null-settings-degrades-to-absent`
-> `new-workspace-runtime-context-null-results-degrade-to-absent` (9 goldens): it
now covers both reads, not just settings. README updated to match.

No sender recording moved: resolving the value pool across all 153 goldens shows
`sender` and `payloads` byte-identical everywhere.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): name the ui.get result shape so the changed cast carries a rationale

The inline union wrapped over four lines and tripped the changed-code casting gate
as a new assertion; a named alias keeps the cast on one line under a SAFETY note.
No behaviour change.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the golden baseline to the cast-rationale commit

Header-only: `baseline` on all 153 goldens. The re-record is inert — no golden
moves observationally and no field other than `baseline` changes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the ui.get trust blank, and correct two stale acceptance comments

The goldens cannot catch a regression to `if (uiResult?.result)`: the scenario's
success reply is `{"ui":{}}`, so every partition of
matrix-settings.workspace-context-ui.get-1 records the same `trust:{}` state. The
new case answers once with real trust and again with a null result on a fresh
client, which is the only shape where skipping the blank is observable —
trustedOrcaHooks gates the setup-hook approval prompt in
use-new-workspace-create-submit.ts, so a stale value would skip it.

settingsRead's comment still claimed workspace context, which this branch moved to
optionalSettingsRead; both comments now name their real callers.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the golden baseline to the trust-blank commit

The record fence rejected the previous pin ("Product sources or lockfile differ
from the pinned main baseline"), so the branch was no longer re-recordable.

Header-only: `baseline` and `recorderSha256` on all 153 goldens — the digest
covers pilot-scenarios.json, whose only edit is that baseline. The re-record is
inert: 0 goldens move observationally and no other field changes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): name the right operation per refuse-after-data probe

Three of the five probes read through optionalSettingsRead, not settingsRead:
repo metadata and resume metadata already did, and workspace context does as of
this branch. The sentence now splits them and states why the split does not move
what the probes record.

Markdown is excluded from recorderSha256, so no re-record.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the recorder's unhandled-rejection capture

This branch removed the last two goldens that recorded an unhandled-rejection
effect, so nothing exercised unhandled-recording.ts any more: gutting the emit to
`void captureError(error)` leaves all 153 goldens comparing clean. The unit test
drives a detached rejection through the window and asserts both the effect and
the listener restore. README says so where it describes the capture.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-digest the goldens for the new recorder test

Header-only: `recorderSha256` on all 153 goldens, which covers every non-markdown
file under rpc-recording/ and so moves for the added test file. The re-record is
inert: 0 goldens move observationally and no other field changes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin each RPC golden to its own scenario input, not the whole manifest (#20562)

* refactor(mobile): pin each golden to its own scenario input, not the whole manifest

`recorderSha256` covered the recorder directory plus `pilot-scenarios.json`, so every golden's
header was a function of every other family's scenarios. Adding a family for one domain re-digested
all 153 goldens and put a conflict on that line in every domain branch in flight, which serialized
the step-4 fan-out.

Split the two things it conflated. `recorderSha256` now covers the recorder directory only, with
unchanged semantics: a recorder edit still forces a full, deliberate re-record. A new
`scenarioSha256` pins the scenario input that golden was recorded from — every scenario
`runRecording` consumed for it, in order — canonicalised through `captureValue` so an
explicit-undefined param stays distinct from an absent one. `goldenRecording` takes that list
instead of just its first member.

The variants are hashed rather than the base they expand from because they are what was recorded: a
matrix site, its replayed normal result and its partition replies are all visible in them without
the derivation having to be restated. `derived-goldens.ts` is that derivation, extracted from
`family-recordings.test.ts` so the digest and the recording agree by construction — a property test
that restated how a matrix or schedule expands could agree with itself and with nothing else. It
reproduces exactly the 153 golden ids on disk, and the census the suite already ran (every family
matrixed, no stale normal-result inventory entry) now reads off its output.

`golden-header-digest.test.ts` pins the four properties:

- a new family in the manifest moves zero existing goldens' headers, and derives two of its own
- editing one field of `b1` moves exactly `b1` and its family's four matrix goldens — not the two
  other `legacy-inventory` scenarios, and not the goldens that expand from `inventory-lifecycle`
- editing a recorder file still moves every golden's `recorderSha256`, and no `scenarioSha256`
- `recorderSha256` is unchanged by the manifest's contents, and no longer reads the file at all

`GOLDEN_FORMAT_VERSION` goes to 4: a version-3 header has no `scenarioSha256`, and `compareGolden`
walks the expected header's keys, so a reader that accepted one would compare that golden's own
scenarios as though they were unpinned.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the 153 RPC goldens for the split digest

Recorder edit, so every golden needs rewriting. Recorded from the pinned baseline
`16d1ab81d3` with this branch's recorder overlaid, per the README's procedure: main has
moved past the baseline, so recording in place would have failed the product-source fence.

Three header fields moved and nothing else did:

- `recorderSha256` 6a12160a87… -> 2fda557f58…, one value across all 153 files
- `scenarioSha256` added, 153 distinct values
- `goldenFormatVersion` 3 -> 4

No observation, checkpoint, value-pool entry, `baseline`, `lockfileSha256` or `platform` changed:

    git diff -U0 -- mobile/rpc-foundation | grep -E '^[+-]' | grep -vE '^(\+\+\+|---)' \
      | grep -vcE 'recorderSha256|scenarioSha256|goldenFormatVersion'
    0

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): certify the pilot goldens from the derivation that digests them

`pilot-recordings.test.ts` restated `[scenario]` instead of consuming `pilotGoldens`, so the claim
that a golden's `scenarioSha256` is a function of the same derivation that records the file held
only for the 75 family goldens: dropping a scenario from `pilotGoldens` left the whole suite green
and put that golden outside the header oracle. The pilot suite now iterates `pilotGoldens`, and a
census fails if the derivation and the goldens directory disagree in either direction — which also
closes the pre-existing orphan-golden gap.

Also from review: pin the cross-sibling replay that hashing the generated variants buys (a matrix
golden's `normal` partition replays a sibling's recorded reply, so editing that sibling must move
it); state the real reason for the format bump, which is the diagnosis a version check gives rather
than a rejection the byte compare already made; drop the fourth property test, which re-proved what
tests 1 and 2 and `recording-runner`'s digest test already fail on; and drop a guard in
`scenarioSha256` that its only caller reaches after an identical one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the 153 RPC goldens for the review edits

Recorder files changed, so `recorderSha256` moved. Recorded from the pinned baseline with this
branch's recorder laid over it, per the README's migration-branch procedure. That one header field
is the only line that moved in all 153 files: `scenarioSha256` and `goldenFormatVersion` are
unchanged, and no observation moved.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): correct the recording suite's test count

Round-2 review: the README said 200 tests; the suite is 209 after the five
added here. Markdown is outside recorderSha256, so no golden moves.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the 153 goldens on the merged baseline

Four header fields moved and nothing else. Proven against origin/main: every
changed line in all 153 files is one of these, and the file set is unchanged.

- `recorderSha256` 70aa6f59e0 -> 58a461dbc9: this branch's recorder, and it now
  digests only the recorder directory, not the scenario manifest.
- `scenarioSha256` added, 153 distinct values over 153 goldens.
- `goldenFormatVersion` 3 -> 4 for that added field.
- `baseline` 5ec0b2698f -> e53f1557e1, the merge's repoint onto the real main
  commit. #20563's value was a branch commit the squash left unreachable, so the
  record fence's `git diff <baseline>` could not resolve it.

No checkpoint, value pool, effect or settlement byte moved, so main's recorded
behaviour is carried over intact.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): account for main's added recorder test in the suite count

The merge brought in `unhandled-recording.test.ts`, one test, so the recording
suite is 210 rather than the 209 this branch documented. Markdown is excluded
from `recorderSha256`, so no golden moves.

* fix(native-chat): stop a bounded tail read from moving the chat cursor past unapplied rows (#20581)

* fix(native-chat): stop a bounded tail read from moving the chat cursor past unapplied rows

A structured chat pane could latch "Working for N" forever after the agent had
finished, showing the send arrow rather than Stop, while the sidebar and
`worktree ps` correctly read idle.

The client replica has one position (`state.cursor`) and one body. Two
operations keep those consistent: replace (both from one host snapshot) and
append (rows contiguous with the cursor). The `tail-page` branch was a third
thing: it took the cursor from the journal head, the items from a bounded page
(200 items, byte-capped), then merged retained client submissions over the
page's. Under continuous journal writes the client is always slightly behind,
so the branch ran on every window focus and on every pane re-activation. When
more than a page of rows had landed since a send, that send's user item fell
off the page, its submission was not carried, the retained `pending` survived,
and the cursor jumped past the dispatch-acceptance row. Nothing re-sends it: a
batch carries only touched items and that submission is never touched again.

Delete the third operation rather than guard it. A live subscription is now the
only thing that moves the cursor, and `subscribe({ cursor })` already replays
exactly the missed rows.

- remove the window `focus` listener and the owner/transport `refresh` contract
- skip warm hydration: a retained owner subscribes at its applied cursor
- cold hydration keeps its history read, applied as the existing `snapshot`
  (replace) event rather than `tail-page`
- delete the `tail-page` action and its reducer branch
- delete `resumeCursor` and `shouldAdvanceStructuredResumeCursor`; two cursors
  with two advancement rules were how position and body drifted apart

`older-page`/`loadOlder`, the unattached-refusal grace, generation guards and
the coalescer are unchanged. No host, wire or schema change.

Also fixes a second cost of the same branch: focus during a busy turn discarded
paged-in older items, shrinking the transcript to one bounded page mid-turn.

* fix(native-chat): preserve unavailable mixed-version session fences

* refactor(mobile): send the task workspace-creation domain through typed RpcOperations (#20568)

* test(mobile): record main's task workspace-creation RPC behaviour before migrating it

28 scenarios over nine task senders, recorded from main so the step-4 migration of
the workspace-creation half of src/tasks/ has a frozen answer to compare against.
Four senders mount as plain exported functions; three are model-chained hooks
mounted the way the settings adapters mount theirs.

The 153 existing goldens change header-only (`baseline`, `recorderSha256`): any new
scenario re-digests the recorder, and the pinned baseline had drifted from main
because the source-control migration landed. Content is byte-identical on all 153 —
verified field-by-field against HEAD.

`operation-module-loader.ts` now shares src/transport/rpc-delivery-ambiguity.ts with
mounted modules instead of evaluating a second copy. The mark is a WeakSet keyed on
the rejection object, so the copy the loader built had an empty registry and every
delivery-unknown rejection read as a definite failure inside the operation under
test — worktree.create's whole replay path was unreachable. With one registry,
`tw-create-retry-ambiguous-after-drop` records the create still pending at the
reconnect wait and abandoning at exactly 20000 ms, while the unstamped-create
scenario records the same rejection surfacing at 0 ms. No existing golden moves:
no other mounted module consumes the mark.

`task-preferences-optimistic` is re-anchored above the send rather than across it,
so migrating this file does not have to move the anchor. It still kills, and for
the same reason: the preset the screen shows no longer follows the tap.

Scenarios deliberately pin the empty-message refusals (`*-refused-empty-message`,
`*-empty-message`), because a refusal with no message falls back to the screen's
copy while a transport error with no message does not, and the two paths are easy
to collapse when a call site moves behind an acceptance policy.

Goldens: 153 -> 201, 2.9M -> 3.7M.

* test(mobile): format the recording manifest and re-digest the goldens

`oxfmt --check` from mobile/ collapses a one-element `sites` array in each new
scenario. The JSON value is unchanged — verified by comparing both files parsed
and key-sorted — but the manifest is inside `recorderSha256`, so all 201 goldens
carry a new digest. Every other field, header and observation alike, is
byte-identical.

Re-recorded in a separate worktree at the previous commit so the goldens stay
attributable to main's product source rather than to the migration that follows.

* test(mobile): separate the goldens from the migration, and re-digest

The previous commit accidentally carried the product migration alongside the
manifest format, which both broke the commit that is supposed to prove parity and
left the suite red: the digest was recorded without a comment move that a lint fix
had made inside the adapter, so all 201 goldens failed their `recorderSha256`
header.

This backs the product half straight out again — the next commit re-applies it
byte-for-byte — and re-records from the pinned baseline in a separate worktree
carrying this branch's recorder, per the procedure in the recording README. Every
field except `recorderSha256` is byte-identical to the previous commit's goldens on
all 201 files, so no observation moved in either direction. The suite is green here
with main's product source, which is what makes the next commit's "no golden
changed" claim mean something.

* refactor(mobile): send the task workspace-creation domain through typed RpcOperations

12 of src/tasks/'s 37 raw-port files now send through a declared operation instead of
the raw request port: 36 references to 0, leaving 25 files and 73 references for the
provider item/detail/mutation half. No golden moved — `git show --stat` on this commit
touches nothing under mobile/rpc-foundation/, which is the parity claim.

Twenty-two operations over twenty methods, in four modules named for what they send:
workspace create (create, PR/MR base resolution, create-time capabilities), workspace
source (SSH connect/state, agent detection, repo hooks, sparse presets, ref search),
task runtime (status, ui.get/ui.set, preflight, Linear status, settings.update) and the
Smart picker's provider reads.

Two methods carry two policies each, and both pairs are named. `status.get`: the Tasks
screen cannot hydrate without it and surfaces the host's message, while create-time
capability probing degrades to "no capabilities" and creates anyway — so one throws on
refusal and one skips. `ui.set`: two sites await it, one is fire-and-forget and never
interprets the reply at all. Both pairs share one reader, so no method has two readers.
No new acceptance policy.

worktree.create keeps its delivery-unknown contract. `request` returns the transport
promise itself, so the retry loop catches the object the transport marked; two new tests
assert `toBe(marked)` in one direction and that an unmarked rejection stays unmarked in
the other, because a mark added on the way out would replay a create the host never
received. `tw-create-retry-ambiguous-after-drop` records the create still pending at the
reconnect wait and abandoning at exactly 20000 ms.

Three sites still read the raw refusal envelope before interpreting, because the code or
the message decides the route and no acceptance policy carries either through: the create
retry needs the message for `isRetryableWorktreeCreateConflict`, and the paste lookup
needs `method_not_found` to retire the slug probe host-wide. Both are documented at the
site.

The hydration barrier keeps raw requests inside its `Promise.all`. main's group rejects as
soon as one leg rejects; `startRpcOperation` + `interpretAtRpcBarrier` would wait for the
slowest peer and let a later policy surface a different error. Interpretation stays after
the `stale` guard, where it was.

`WorkspaceCreateParams` is now `RpcSendParams<'worktree.create'>` rather than
`Record<string, unknown>`, which types the builder and the operation together; every field
the three builders already sent typechecks against the host schema unchanged.
`RpcSendArguments` now also makes params optional for a method whose params type has no
required field, because `preflight.check` is such a method and main sent it none —
requiring `{}` would have put a new object on the wire.

The Mobile Tasks source-parity hashes move for the same reason bound settings requests
moved them: the method string and the envelope read leave the screen. The signature diff
is evidence rather than a re-pin — `semantics` is a pure deletion of 22 `rpc:` call
signatures and 22 method literals with nothing added, statement/declaration/render/style
counts are unchanged, and render tokens, styles and declarations are byte-identical.

* test(mobile): split the task workspace adapters at the sender/hook seam

The single adapter file reached 344 lines against mobile's 300-line limit. CI lints
every file, so this is red there even though the changed-code gate does not report it.
Split along the seam the recording README already draws: exported async senders that
take a client and need no React host, and the drawer's three model-chained hooks.
No adapter body changed.

Both files are inside `recorderSha256`, so all 201 goldens carry a new digest. Every
other field is byte-identical, verified file by file. Re-recorded from the pinned
baseline in a separate worktree carrying this branch's recorder, so the goldens stay
attributable to main's product source.

* refactor(mobile): give the one-key unchecked reader a name

Four readers were the same three lines: read one property off the reply, wrap
it unchecked. `rpcUncheckedMemberReader` is the one-key sibling of the existing
`rpcUncheckedPayloadReader`, so the annotation and the closure go away at each
site. The pilot's `commitCompareEntriesReader` is converted too, so the helper
has no longhand twin left to copy from.

No behaviour change: the helper composes the same `rpcReadUnchecked` over
`rpcPayloadMember`, including the property-read exception on a null result.

* test(mobile): record the local arm of workspace agent detection

`preflight.detectAgents` was the one migrated operation with no recorded
coverage: the ssh adapter hardcoded `connectionId: 'ssh-1'`, so the detection
effect's ternary only ever took the remote arm and the local call site could be
repointed at another method without a golden noticing.

The adapter now takes the connectionId as a parameter and registers twice;
`tasks.workspace-ssh-local` mounts the same hook with no connection, which is
the only difference the effect branches on. Recorded at the pinned baseline
with this branch's recorder laid over it, so the new golden is main's
behaviour and the migrated code has to reproduce it — it does.

Goldens: two added (`tw-workspace-ssh-local-agents` and its reply matrix). The
other 201 changed on `recorderSha256` only, because the adapter edit moves the
recorder digest every golden pins.

* test(mobile): drive workspace create and the Linear list to a recorded wire

Two operations passed a policy swap unnoticed, both because no golden reached
their acceptance branch.

`worktree.create`: the create hook's fixture resolved setup to a prompt, so all
three settings.task-workspace scenarios stopped before the request and the only
consumer that hands a refusal to interpret was never recorded. The adapter now
takes the setup resolution as a parameter and registers a second family that
resolves it, so createWorkspace runs to the wire. Two scenarios: a Linear item
that creates directly, and a GitHub pull request that resolves its base first,
which also puts this hook's built params — start point, generated display name,
agent launch fields — in a golden for the first time. The existing prompt
family is untouched, so its recordings still pin that branch.

`linear.listIssues`: it appeared only in a non-base scenario, and the matrix
reads the family base, so the family had no partition for it. The base now
lists assigned issues after searching.

Goldens: five added. Five moved beyond the digest, all derived from the
smart-search base that gained the list leg. The other 198 changed on
`recorderSha256` only. Recorded at the pinned baseline with this branch's
recorder laid over it, so every new golden is main's behaviour.

* test(mobile): drop the unreachable unmount branches from the task adapters

Nothing dispatches `unmount` to these three adapters: the only producer is
`lifecycleSchedules`, driven from a hardcoded five-id list that names no
task-workspace family, and it pushes a `remount` right after, which these
adapters would throw on. The branch read as lifecycle coverage that was never
wired up. `dispose: hook.unmount` already tears the mount down.

Goldens re-recorded at the pinned baseline because the recorder digest moved;
`recorderSha256` is the only line that changed in all 208.

* test(mobile): re-record the goldens at main's post-squash baseline

Recorded from a detached checkout of e53f1557e1 (main's unmigrated
product code) with this branch's recorder laid over it, so the parity
claim stays non-circular.

- `baseline` repinned to e53f1557e1 on all 208 goldens; main pinned
  5ec0b2698f, a pre-squash branch commit not reachable from main.
- `recorderSha256` moved on all 208 because this branch's adapters are
  in the whole-manifest digest.
- 55 task-workspace goldens re-recorded at the new baseline.
- No other line in any of main's 153 goldens changed.

Baseline repinned to 50e752fc66 and all 208 goldens recorded from that

recorderSha256 moves on every golden because the task-workspace adapters
live in the recorder directory. scenarioSha256 does not move on any of
main's 153: the manifest only adds 31 scenarios and edits none, which is
the property #20562 was built to give.

* feat(ai-vault-search): construct the session search indexer in the scanner service behind a setting (#20516)

* feat(ai-vault-search): persist agent-session search consent and retention

Two booleans and nothing else: `enabled` and `historyDays`, off by default
because building the index reads every transcript on the machine. No `paused` --
the PR 3 indexer is immutable, so every change is close-and-construct.

The settings IPC normalizes a write like every other field and hands the change
to the index; there is no UI for it until PR 8.

* feat(ai-vault-search): hold one indexer and engine pair per host

The object that owns a host's live index and the three recipes that change it.
The indexer is immutable, so a settings change is close-and-construct, disabling
is close with no replacement, and clearing is close, remove the database,
construct. The new instance's first sweep purges a narrowed window and admits a
widened one, so neither needs a code path.

The database sits beside the scanner's parse cache, one file per host. A runtime
with no node:sqlite can hold no index at all, which the Node 18 floor on orcad
and the relay makes a real case rather than a hypothetical one.

* feat(ai-vault): let the scanner child own the session search index

The transcript reader runs in that child, so the index consumer has to as well:
one read serves both the session list and the index. Three request operations
(search, status, reconcile) and one fire-and-forget settings message carry
everything a parent needs; main never opens the database file.

The init frame becomes a factory because it is read at every spawn, so a
respawned child sees current consent rather than the first frame's. A child
holding a running index is never idle from the parent's side, so idle retirement
is suppressed while the index is on -- retiring it would stop the reconcile loop
until some later scan happened to respawn one.

Both files this lands in were already at the max-lines ceiling, so three
collaborators move to where they belong rather than being disabled around: the
invalidation deadline into the class that owns invalidations, call cancellation
and the start requeue into the call-state module, and orcad's flag parsing into
its own file.

* feat(ai-vault-search): register a search service on every host that answers

Without a registered service a host answers no-service, which means "this host
does not have the feature" rather than "the index is off". All three hosts now
answer the second thing.

The desktop forwards to the scanner child. orcad and the SSH relay daemon have
no such child -- orcad ships only the watcher and daemon entries, and the relay's
AI Vault sidecar runs the remote scanner, which publishes nothing to the
transcript channel -- so on those two the index lives in the process that would
drive its reads, gated on a runtime that has node:sqlite at all.

The relay registers with consent off and no way to turn it on: nothing carries a
setting to a remote host yet. That is the honest state, and it is still worth
registering, because it is what tells a client the difference between off and
too old.

* test(ai-vault-search): price a warm pass over five thousand transcripts

The number the reconcile interval will be revisited against, measured rather
than argued: a warm sweep stats every file under every root, a warm cycle stats
the newest N per agent, and neither reads what the index already holds. It does
not tune the interval.

* fix(ai-vault-search): answer the casting gate without assertions

main's new type-assertion rule reaches every file this branch touches. All nine
sites drop the cast rather than carry a SAFETY: rationale: the operation guard
narrows with `in`, the sqlite probe narrows the builtin it loads, the child test
keeps the discriminated reply instead of widening it, and the settings resolver
takes `unknown` -- which is what it really reads, since a persisted profile can
hold a value no version of this code wrote.

* fix(ai-vault-search): let a refreshed scan root reach the live index

The parent re-resolves scan roots before every policy push, precisely so a
WSL distro or extra Codex home that appeared since the child spawned enters
the window. The child forwarded only the settings to a live instance and used
the roots solely in its `??=` initializer, so those roots were dropped for the
child's lifetime.

The indexer stays immutable: a structurally different root set closes the pair
and constructs a new one, the same way a changed databasePath already does.
Compare via `sameSessionSearchRoots` rather than a plain JSON compare, because
nothing fixes the key order two producers write; lists are sorted too, since
the indexer walks every root and a re-enumeration that reorders is not a
change. An unchanged set still never restarts a running index.

The orcad and relay in-process hosts resolve roots once at install and never
re-apply, so they have no such seam.

* fix(ai-vault): restart the scanner child the index is holding

Three review items.

The hold keeps a child alive for the index, but only a queued call ever
started one: `pump()` skipped a hold with an empty queue, so an idle indexing
child that crashed, or an `ensureChild()` that failed at start, left indexing
stopped until an unrelated request happened to arrive. `pump()` now starts the
child the hold requires, which is also the restart callback the fault policy
already schedules, so the existing delay and circuit bound the retry exactly as
they bound a queued call's start. `updateSessionSearch` goes through the same
seam instead of its own `ensureChild` call.

A search registers no AbortController, so a cancel sent for a search id was
added to the `cancelled` set and never consumed. Nothing can reach that today
-- no caller passes a signal and the child answers in milliseconds -- so this
is only a leak of ids: consume it when the search settles.

The orcad argument doc claimed a `--`-prefixed value stays a flag. The parser
takes the next token regardless, and orcad-launch-contract.test.ts pins that,
so the doc is what was wrong. Behaviour is unchanged.

* Bump mobile app.json to 0.0.50 (#20661)

* fix(native-chat): bound a dispatch reason before it reaches the journal row (#20654)

`AgentJournalSubmission.reason` was the only unbounded field written by
Orca's own code. `dispatchSafely` sets it from the adapter's raw
`error.message` and `journalDispatchRowBuilder` stored it verbatim, so a
provider error carrying a multi-megabyte body -- a stringified HTTP error
payload, say -- reached the row at whatever length the provider sent, and
stayed on disk at that size for the life of the journal.

It now goes through `boundInlineText` with the journal's existing inline
limit, the same idiom already applied to arbitrary text on the Claude and
Codex translation paths.

The bound must stay head-preserving. `dispatchRejectionWasTransportWriteFailure`
prefix-matches the value, and `dispatchRejectionReasonIsInternal` builds on
it, so a bound that kept the tail instead would stop classifying a clipped
transport failure and render raw provider text to the user as an ordinary
rejection notice. A test pins that, and clipping stays marked rather than
silent so a truncated reason is never presented as the provider's complete
explanation.

Rows written before this keep their full text, so readers can still meet an
unbounded reason.

* fix(native-chat): keep a resumed transcript pinned to its end (#20651)

* fix(native-chat): keep a resumed transcript pinned to its end

Follow state was recomputed from distance on every scroll event, and a pin writes scrollTop itself, so the browser reports that write back as a scroll event a frame later. Once a resumed session's later history pages and settling row heights had moved the end away from it, that echoed event read as the reader leaving and the pin was dropped for good, stranding them mid-transcript. Measured in Chromium: a pin followed by same-task growth delivers a scroll event reading 2000px from the bottom, indistinguishable from a reader scrolling up.

Pins now go through the virtualizer instead of writing scrollTop directly, so both parties resolve the end through the same maximum rather than holding rival definitions of it. Whether the reader left is now a question of provenance rather than distance: an offset this transcript wrote is never a departure. The end test reads live geometry, because the virtualizer's own isAtEnd subtracts a cached offset from a live maximum and this handler runs before that cache is refreshed. overflow-anchor:none stops the engine moving scrollTop under a settling row, which would otherwise look like the reader.

This does not make ownership singular. The virtualizer still writes autonomously from several paths and those writes stay unattributed; what this removes is the rival definition of the end, not the second writer.

Post-mutation refresh failures are logged separately, not surfaced as toasts

a shared handler to reduce duplication.

* fix(source-control): only dismiss entry failures from the owning worktre

Track which worktree owns the shared entry-failure toast slot. When a mutation
completes, only dismiss the slot if the completing worktree is the one that
raised the failure — a slow retry in one worktree should not erase a failure
another worktree has since raised into the slot.

* fix(store): stop two no-op writes from re-running every selector in the app (#20641)

* fix(store): stop two no-op writes from re-running every selector in the app

zustand bails out of a `set` only when `Object.is(next, state)`. Two updaters that
mean "nothing changed" hand it a fresh reference instead:

- `setWorkspacePortScanRefreshing` wrote unconditionally — the one action in its
  file that did; its four siblings all early-return `state`.
- `applyGitHubPRRefreshEvent` ended its no-op branch with `: {}`, and
  `Object.assign({}, state, {})` reproduces every field unchanged while still
  notifying. ~20 sibling sites in the same store already use `return state`.

Both rebuild the root and wake every subscribed selector (~2.2k per the listener
census). Renders are unaffected — the selection is unchanged — so the cost is
wasted selector evaluation, not commit pressure. The resulting state looks
identical either way, which is why it goes unnoticed; both tests therefore count
subscriber notifications rather than asserting state.

* 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.

* feat(runtime): stream file uploads instead of buffering whole files (#16106)

* feat(runtime): stream file uploads instead of buffering whole files

Staging read each dropped file whole with readFile(), base64-encoded it
(a 4/3 expansion), and passed the string through IPC to the renderer,
which re-chunked it. Peak memory was ~2.3x the file size before a byte
moved, so a 25 MB per-file cap existed to protect the heap.

Staging now records identity only. The byte pump moves into main, where
the file handle and the runtime socket both live: 384 KiB slices (512 KiB
once base64-encoded, matching the chunk size the renderer used) appended
through the existing files.writeBase64Chunk RPC. Peak memory is one slice
regardless of file size, so the ceilings become user-safety limits on an
unattended transfer — 2 GB per file, 8 GB per drop — and over-limit errors
name both the size and the limit.

Because staging and streaming are separate calls, the staged entry carries
size, inode, device and mtime, and the streamer re-checks all four against
the pre-open lstat and against the handle it actually reads. A source
replaced or rewritten at the same size between the two calls is refused
rather than uploaded under the original name. The post-read check compares
mtime as well as size, so an in-place rewrite mid-transfer aborts before
commitUpload renames anything into place.

O_NOFOLLOW, realpath containment and stat identity are preserved, and the
pairing revision plus the runtime id ride every chunk, so a re-pair or a
replacement runtime aborts instead of appending the rest of the file to a
different host.

No wire change: files.writeBase64Chunk and its params are untouched, so
old and new hosts behave identically. The SSH import path is separate and
unchanged. The web client has no local filesystem to stream from and says
so instead of failing obscurely.

* fix(runtime): close the empty-upload and per-drop budget holes

Two gaps the first pass left open.

A zero-byte source returned before the post-transfer identity check, so a
file that gained content during the empty write's round trip committed as
an empty file at the user's chosen name. The empty chunk now falls through
to the same final check the slice loop uses.

Each staged source also started its own byte counter, so the 8 GB ceiling
capped one source rather than the drop: five 2 GB files staged cleanly at
10 GB total. The IPC handler now carries one budget across sourcePaths and
adds only what each source actually staged. The per-file ceiling is still
re-enforced where the bytes move; the drop total holds at staging because
identity enforcement means each file streams exactly the bytes measured.

* docs(runtime): name the invariants the upload helpers carry

* fix(runtime): name the source in errors and stop uploads with their window

Three problems an independent review turned up.

A dropped file's relative path is '', so the over-limit error read "'' is
3 GB, over the 2 GB per-file remote import limit" — the message this change
exists to fix, naming nothing. Errors now fall back to the file's own name;
the staged entry keeps '' so the destination path is unaffected. The
streamer had the same shape, falling back to the hidden .orca-upload-<nonce>
temp destination, a path the user never chose.

The byte loop used to live in the renderer and died with it. Moving it into
main meant closing or reloading the window left the rest of a multi-GB
transfer running, with the renderer's temp cleanup never reaching its
finally. An AbortSignal now rides the caller's lifetime and every chunk, is
re-checked per slice, and main sweeps the abandoned temp path itself when
the renderer is no longer there to do it.

Upload failures also reached the import result wrapped in Electron's
"Error invoking remote method '...'" prefix, because the throw crossed IPC
instead of happening in-renderer; extractIpcErrorMessage unwraps it.

An existing staging test asserted the empty-name message, so it encoded the
bug rather than catching it; it now asserts the file name.

* test(runtime): cover the containment check and the per-chunk host guards

The "escapes the dropped root" test only reached the lstat symlink guard,
so assertEntryInsideRoot had no coverage at all. The shape that actually
needs it is a regular file under a symlinked intermediate directory: lstat
sees a plain file, and realpath containment is the only thing that refuses
it. Disabling the guard now fails this test and nothing else.

Nothing asserted that the SSH target, connection generation and execution
host reach the writeBase64Chunk params either — the renderer tests stop at
the IPC boundary, so the streamer's half of that contract was untested.

* fix(runtime): survive a straggling append when sweeping an aborted upload

Aborting rejects the in-flight chunk locally, but the host may still apply
that append, and appends open with flag 'a' — which recreates the file the
sweep just deleted. The delete and the straggler also race: they are
separate calls on a queue that is not ordered between them.

Slices are strictly sequential, so at most one append can be outstanding.
A second pass after it has had time to land is therefore sufficient, not
merely a heuristic. The sweep moves out of filesystem-mutations.ts into its
own module so the behaviour is testable directly.

Found by an independent review pass, which also pointed out that the
"escapes the dropped root" test only reached the lstat symlink guard.

* fix(runtime): abort uploads only when the document commits, and honour manual disconnect per chunk

did-start-navigation fires before will-navigate blocks an external link or a
stray file drop, and the renderer survives those (verified against Electron 43
with a hidden window). Aborting there killed a healthy upload with a misleading
'window went away' error. did-navigate fires only once a new document has
replaced the caller.

The renderer's per-chunk calls used to go through the IPC handler that refuses
a manually disconnected environment; the loop in main made no such check, so a
disconnect mid-upload kept pushing the rest of the file. The handler now
resolves the selector to an environment id and the streamer checks it per slice.

Adds slice-boundary coverage against the real chunk schema and host write
flags, staging-to-stream on a real filesystem, and handler-level lifetime tests.

* fix(ui): contain idle caret paint so agent panes stop burning CPU (#10554)

An idle agent pane kept ~40% of a core busy just by being frontmost. The
xterm cursor and the native chat caret blink with no paint-containment
boundary, so Chromium treated each blink as damage to the whole pane
ancestry and re-rasterized it twice a second.

- `.xterm-container` and the native composer's input shell get
  `contain: paint`, bounding blink damage to the surface that blinks.
- The mention hint gains `z-20` to match the slash picker: a contained
  element becomes a stacking context and paints at z-index 0 in tree
  order, which would otherwise cover the hint's drop shadow.

Also records that DECSCUSR pins `decPrivateModes.cursorBlink`, which wins
over the option in `_updateCursorBlink` — so parking `cursorBlink` does not
reliably stop a hidden pane blinking. Pre-existing, documented only.

…anner service behind a setting (stablyai#20516)

* feat(ai-vault-search): persist agent-session search consent and retention

Two booleans and nothing else: `enabled` and `historyDays`, off by default
because building the index reads every transcript on the machine. No `paused` --
the PR 3 indexer is immutable, so every change is close-and-construct.

The settings IPC normalizes a write like every other field and hands the change
to the index; there is no UI for it until PR 8.

* feat(ai-vault-search): hold one indexer and engine pair per host

The object that owns a host's live index and the three recipes that change it.
The indexer is immutable, so a settings change is close-and-construct, disabling
is close with no replacement, and clearing is close, remove the database,
construct. The new instance's first sweep purges a narrowed window and admits a
widened one, so neither needs a code path.

The database sits beside the scanner's parse cache, one file per host. A runtime
with no node:sqlite can hold no index at all, which the Node 18 floor on orcad
and the relay makes a real case rather than a hypothetical one.

* feat(ai-vault): let the scanner child own the session search index

The transcript reader runs in that child, so the index consumer has to as well:
one read serves both the session list and the index. Three request operations
(search, status, reconcile) and one fire-and-forget settings message carry
everything a parent needs; main never opens the database file.

The init frame becomes a factory because it is read at every spawn, so a
respawned child sees current consent rather than the first frame's. A child
holding a running index is never idle from the parent's side, so idle retirement
is suppressed while the index is on -- retiring it would stop the reconcile loop
until some later scan happened to respawn one.

Both files this lands in were already at the max-lines ceiling, so three
collaborators move to where they belong rather than being disabled around: the
invalidation deadline into the class that owns invalidations, call cancellation
and the start requeue into the call-state module, and orcad's flag parsing into
its own file.

* feat(ai-vault-search): register a search service on every host that answers

Without a registered service a host answers no-service, which means "this host
does not have the feature" rather than "the index is off". All three hosts now
answer the second thing.

The desktop forwards to the scanner child. orcad and the SSH relay daemon have
no such child -- orcad ships only the watcher and daemon entries, and the relay's
AI Vault sidecar runs the remote scanner, which publishes nothing to the
transcript channel -- so on those two the index lives in the process that would
drive its reads, gated on a runtime that has node:sqlite at all.

The relay registers with consent off and no way to turn it on: nothing carries a
setting to a remote host yet. That is the honest state, and it is still worth
registering, because it is what tells a client the difference between off and
too old.

* test(ai-vault-search): price a warm pass over five thousand transcripts

The number the reconcile interval will be revisited against, measured rather
than argued: a warm sweep stats every file under every root, a warm cycle stats
the newest N per agent, and neither reads what the index already holds. It does
not tune the interval.

* fix(ai-vault-search): answer the casting gate without assertions

main's new type-assertion rule reaches every file this branch touches. All nine
sites drop the cast rather than carry a SAFETY: rationale: the operation guard
narrows with `in`, the sqlite probe narrows the builtin it loads, the child test
keeps the discriminated reply instead of widening it, and the settings resolver
takes `unknown` -- which is what it really reads, since a persisted profile can
hold a value no version of this code wrote.

* fix(ai-vault-search): let a refreshed scan root reach the live index

The parent re-resolves scan roots before every policy push, precisely so a
WSL distro or extra Codex home that appeared since the child spawned enters
the window. The child forwarded only the settings to a live instance and used
the roots solely in its `??=` initializer, so those roots were dropped for the
child's lifetime.

The indexer stays immutable: a structurally different root set closes the pair
and constructs a new one, the same way a changed databasePath already does.
Compare via `sameSessionSearchRoots` rather than a plain JSON compare, because
nothing fixes the key order two producers write; lists are sorted too, since
the indexer walks every root and a re-enumeration that reorders is not a
change. An unchanged set still never restarts a running index.

The orcad and relay in-process hosts resolve roots once at install and never
re-apply, so they have no such seam.

* fix(ai-vault): restart the scanner child the index is holding

Three review items.

The hold keeps a child alive for the index, but only a queued call ever
started one: `pump()` skipped a hold with an empty queue, so an idle indexing
child that crashed, or an `ensureChild()` that failed at start, left indexing
stopped until an unrelated request happened to arrive. `pump()` now starts the
child the hold requires, which is also the restart callback the fault policy
already schedules, so the existing delay and circuit bound the retry exactly as
they bound a queued call's start. `updateSessionSearch` goes through the same
seam instead of its own `ensureChild` call.

A search registers no AbortController, so a cancel sent for a search id was
added to the `cancelled` set and never consumed. Nothing can reach that today
-- no caller passes a signal and the child answers in milliseconds -- so this
is only a leak of ids: consume it when the search settles.

The orcad argument doc claimed a `--`-prefixed value stays a flag. The parser
takes the next token regardless, and orcad-launch-contract.test.ts pins that,
so the doc is what was wrong. Behaviour is unchanged.

* fix(mobile): give the page its height and its long press; C1.7 device proof (OTA phase C, C1.9) (#21589)

* fix(mobile): give the Route A document the height its mounted tree measures against (OTA phase C, C1.9)

The document this builder emits carries no stylesheet, so `html`, `body` and `#root` have no
height, and every box react-native-web lays out below the mount is `flex: 1` against a parent
that measures 0. The collapse is silent in every check that existed: the entry stamps `mounted`,
the route tree commits, `innerText` holds every row, and the accessibility tree reports each one
at the offset it would have had. Nothing is painted below the header, and nothing takes a tap —
the list sits inside a scroller the collapse clipped, and a phone reads it to VoiceOver while no
row responds. Lane C1.7 found it on both an iPhone 17 Pro simulator and a Pixel 9 Pro emulator,
and the same bytes reproduce it in headless Chromium.

The fix is the reset Expo's own web template ships for a react-native-web root, emitted inline
because the shell's CSP already allows `style-src 'unsafe-inline'` for the sheet react-native-web
injects at runtime; a linked asset would paint the collapsed layout until it landed.

The render check gains the assertion that would have caught it: the root's box measured against
the viewport, and the one control this route paints with no RPC answered — the New Workspace
button, positioned against the bottom of the root, which the collapse moved to y = -72 — asked
for by `elementFromPoint` at its own centre. Laid out is not reachable, so the check is a hit
test and not another read of the DOM. Without the reset it fails `expected +0 to be 844`.

* fix(mobile): let the page have the long press WebKit was taking (OTA phase C, C1.9)

The shell's WKWebView is built with the default text interaction, so WebKit installs its selection
assistant over the page. A hold on a worktree row raises the selection loupe over the row's own
text and the touch is cancelled before the page's responder sees it, which leaves every
long-press action in the page dead on iOS while a tap works. Lane C1.7 measured it: the same
injected hold opens the row action sheet on the native list and on the page in the Android
WebView, and does nothing in the page on iOS.

It is not the document's to fix, which the device disproved one rule at a time:
`-webkit-touch-callout: none`, `-webkit-user-select: none`, and both together all left the loupe
and left the hold undelivered, and headless Chromium confirms the property computes to `none` on
the page's text, so the CSS reaches it and WebKit's own gesture wins anyway.

The cost is real and named here rather than discovered later: the page has no text selection on
iOS, so selectable `Text` — markdown, diff rows, file preview, chat — cannot be selected there
until a page-side copy affordance exists. Everything the shell already forbids is unchanged, and
Android is untouched.

No unit test: the module's Swift checks compile the seven WebKit-free logic files and never import
WebKit, so a `WKWebViewConfiguration` cannot be built in them. The device proof stands in.

* fix(mobile): make the root reset the template's bytes, not a copy with an addition

The comment said the reset is what Expo's web template ships, and `margin:0` was not in it.
`@expo/cli@55.0.36/static/template/index.html` carries height, `overflow` and the root's flex box
and nothing else, and react-native-web emits `body{margin:0}` in the sheet it injects at runtime,
so the addition only covered the frames before that sheet landed. Nothing pinned it either:
removing it left all 60 tests green, which is the other way of saying it was never load-bearing.

Dropping it makes the string one thing with one source instead of a copy to keep in step with two.
The pins on the rest of the reset are unchanged, and so is the frame that mattered: the root still
has a definite height before the first paint, which is what the collapse needed.

* style(mobile): format the render check with the root formatter

`config/scripts` is formatted by the root oxfmt, not mobile's, and CI checks neither, so a 102-char

`./node_modules/.bin/oxfmt --write` from the repo root; no behaviour change.

"The bytes Expo's web template ships" is false and checkable: the template's own block is
pretty-printed with comments and trailing semicolons at 410 bytes, and this string is 112. What is
actually true, and what the next reader needs, is that it carries the same declaration set and the
same `id="expo-reset"`, minified.

The check read the constant back against itself: `toContain(MOBILE_WEB_APP_ROOT_RESET)` plus two
substrings taken off that same constant. A rule dropped from it took the assertion with it, so
`body{overflow:hidden}`, `flex:1` and the `expo-reset` id were unpinned — and the render check
stays green without the overflow rule, so nothing else held them either.

Each rule is now a literal written here, named one at a time so a failure says which one went, and
the id is pinned beside them. Verified red-first: removing the overflow rule, the `flex:1`, or the
id each fails this test and only this test.

* fix(runtime): detect a same-size terminal artifact swap the granted stat cannot see (#21436)

* fix(runtime): detect a same-size terminal artifact swap the granted stat cannot see

A local terminal-artifact grant pinned the file as `dev:ino:nlink:size:mtimeMs`.
On Linux every one of those can survive an unlink+recreate: ext4 reuses the
just-freed inode (measured: 100% of the time), nlink and size are unchanged for a
same-size replacement, and the mtime clock is tick-quantized to 1ms, so a swap
inside one tick produces a byte-identical identity string. The grant then served
the attacker's bytes as if nothing had changed.

Local grants now also pin a sha256 of the artifact's content, taken from the same
handle as the stat so nothing can swap the file between them, and every local
read, preview and write re-checks it before returning or committing content.

The stat identity string itself is unchanged: the relay recomputes it verbatim to
honour `expectedStatIdentity`, so its format is a wire contract. Remote grants
keep the stat-only check and are untouched.

This is also the mechanism behind the intermittent
`orca-runtime-files-terminal-artifact-io.test.ts` failure on
`rejects stale absolute terminal artifact previews before returning changed
content`: it replaces an 8-byte artifact with 8 different bytes, so whenever the
two writes shared a 1ms tick the product genuinely could not tell them apart.

* docs(runtime): record what the terminal artifact grant checks do not close

The digest makes the same-size swap detectable; it does not make the sequence
atomic. A reader arriving at the access module would reasonably assume otherwise,
so write down the measured limits of the stat identity, why the identity string
cannot change, and the four windows that stay open — the write path's surviving
rename() gap above all.

* fix(mobile): let the shell's page paint a file preview (OTA phase C, C3.0) (#21591)

* fix(mobile): let the shell's page paint a file preview

A file preview has one shape on the wire: the desktop answers a base64 body
and `normalizeMobileFilePreviewResult` composes `data:<mime>;base64,<content>`
for React Native Web's `Image`. Under `img-src 'self'` the browser refuses to
load it, so every image preview in the page paints nothing — reproduced in the
render check, which logged the refusal naming `img-src 'self'` before this.

`data:` is granted to images and to nothing else, so what it admits is what the
page itself composed out of a reply it already holds; `script-src 'self'` and
`connect-src 'self'` are untouched, and `blob:` is not added because nothing in
the closure needs one. Both platform pins narrow from "the header contains no
`data:`" to "`data:` appears on `img-src` and nowhere else", which is the check
that still fails if a later directive grows one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): say what the data: image case actually loads through

Round 1 is right on both counts. In react-native-web 0.21.2 the hidden <img>
the Image component renders carries `alt`, `style`, `draggable`, `ref` and
`src` and no load handlers at all — it is there for the browser's image context
menu and for `getBackgroundSize()`. The load signal comes from
`ImageLoader.load`, which is `new window.Image()` with `onload`/`onerror` on it,
so the `new Image()` in this case is the same mechanism the screen's own load
runs through rather than a stand-in for it.

And the screen maps `onImageError` to "Unable to load preview"
(`MobileFilePreviewScreen.tsx:282`); "Binary preview unavailable" is the
normalizer's `binary_file` branch, which a CSP refusal never reaches.

Comment only. No assertion moves.

has none to give: `data:` is matched as a scheme, so the directive admits any
`data:` image URL and the browser cannot tell one the page composed from one it
was handed. Nor is the content the page's own — the mime type and the base64
body both come from the host, and `normalizeImagePreviewResult` only checks the
mime type is a non-empty string.

The true bound is where the URL goes: it is never fetched as anything but an
image, `img-src` is the only directive admitting it, an image fetch executes
nothing (an SVG inside an `<img>` runs no script), and `script-src 'self'`,
`connect-src 'self'` and `object-src 'none'` are untouched.

Both copies reworded identically, since they are kept in step by the render
check's own policy comparison.

A malformed host `error` and a null settings result both reach a property read that throws.
Both are deliberate behaviour changes; the goldens move in the follow-up commit.

`hostReplyErrorTextOrFallback` passed a truthy non-string through under a `string` annotation.
Its one caller is the in-band `git.commit` failure, and every consumer of that text is display or
prompt copy: `use-mobile-create-pr-runner` and `PrSidebarCreateEmptyState` record it as a commit
failure, `use-mobile-commit-failure-recovery` hands it to `summarizeCommitFailure`, which starts
with `raw.slice(...).replace(...)`. So no consumer needs the value, and the decision is the
fallback rather than `String(value)` — the relay handler declares
`commit(): Promise<{ success: boolean; error?: string }>`, so a non-string is a malformed reply,
and `generatedCommitMessageReader` in the same domain already reads a non-string host error as
absent. The parameter stays `unknown`, which it honestly is, and the `SAFETY` cast is gone.

`useNewWorkspaceRuntimeContext` read settings through `settingsRead`, whose reader preserves
main's `boxed!.settings` throw, so a `null` or absent result threw a TypeError out of the effect —
losing the trusted-hooks publish and the available-provider computation that follow it, not just
the settings. It now uses `optionalSettingsRead`, the operation that already reads a null or
absent result as absent settings, so the reply degrades exactly the way a reply with no `settings`
member does. Reply-side only: same method, same params, same barrier, no wire change.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the goldens the two bug fixes move

Baseline bumped to 3f71999237. Two goldens move an observation; the other 151 move only
`baseline` and `recorderSha256`, which `pilot-scenarios.json` is still digested into.

Observation moves, one claim each:

- `matrix-hostedreview.create-intent-git.commit-1`, partition `inner-false-object-error`:
  `settlements.run.value.error` and `state.outcome.error` go from `{"message":"inner refused"}` to
  `"Commit failed"`. A non-string in-band `git.commit` error is a malformed reply and now reads as
  the screen's copy, converging with `result-absent`, `result-null` and `outer-refused-no-message`,
  which already reported the fallback. The other ten partitions at this site are unchanged.
- `matrix-settings.workspace-context-settings.get-1`, partitions `result-null` and `result-absent`:
  the `unhandled-rejection` TypeError effect (`reading 'settings'`) is gone and `state.providers`
  goes from `[]` to `["github"]`. The effect no longer aborts the rest of the hook, so the
  provider computation runs; `state.settings` stays null because nothing was published, which is
  how a reply with no `settings` member already degraded. The other nine partitions are unchanged.

Header-only moves:

- 9 goldens of the `settings.workspace-context` family rename `namedDeltas` from
  `new-workspace-runtime-context-null-settings-typeerror` — the name now lies, the TypeError is
  fixed — to `new-workspace-runtime-context-null-settings-degrades-to-absent`.
- All 153 move `baseline` and `recorderSha256`. The digest covers `pilot-scenarios.json`, so the
  baseline bump and the rename re-digest every file.

No sender recording moved: both fixes are reply-side, and no golden's `sender` or `payloads` field
differs. The README paragraph that claimed the settings TypeError was preserved is updated, and
now records that the `ui.get` leg of the same hook still is.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): degrade a null ui.get result the way the settings leg now does

One host answers both legs of useNewWorkspaceRuntimeContext, so fixing only
settings.get left the likelier failure in place: a null or absent ui.get result
still threw `reading 'ui'` out of the effect, skipping the provider commit.

Review follow-ups on the same files: reply() returns the literal uncast and the
stub client is FakeSession, dropping two assertions and their SAFETY disables;
the degradation cases now assert absolute state instead of comparing mounts.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the goldens the ui.get leg fix moves

Observational move, 1 golden:

- matrix-settings.workspace-context-ui.get-1: the `result-absent` and
  `result-null` partitions drop their `reading 'ui'` unhandled-rejection effect
  and their state commits `providers: ["github"]` instead of `[]`, because the
  effect no longer throws before the provider commit.

Header-only moves, 153 goldens: `baseline` to the fix commit and `recorderSha256`,
which covers `pilot-scenarios.json` and so re-digests on the delta rename.

The delta is renamed `new-workspace-runtime-context-null-settings-degrades-to-absent`
-> `new-workspace-runtime-context-null-results-degrade-to-absent` (9 goldens): it
now covers both reads, not just settings. README updated to match.

No sender recording moved: resolving the value pool across all 153 goldens shows
`sender` and `payloads` byte-identical everywhere.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): name the ui.get result shape so the changed cast carries a rationale

The inline union wrapped over four lines and tripped the changed-code casting gate
as a new assertion; a named alias keeps the cast on one line under a SAFETY note.
No behaviour change.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the golden baseline to the cast-rationale commit

Header-only: `baseline` on all 153 goldens. The re-record is inert — no golden
moves observationally and no field other than `baseline` changes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the ui.get trust blank, and correct two stale acceptance comments

The goldens cannot catch a regression to `if (uiResult?.result)`: the scenario's
success reply is `{"ui":{}}`, so every partition of
matrix-settings.workspace-context-ui.get-1 records the same `trust:{}` state. The
new case answers once with real trust and again with a null result on a fresh
client, which is the only shape where skipping the blank is observable —
trustedOrcaHooks gates the setup-hook approval prompt in
use-new-workspace-create-submit.ts, so a stale value would skip it.

settingsRead's comment still claimed workspace context, which this branch moved to
optionalSettingsRead; both comments now name their real callers.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): repin the golden baseline to the trust-blank commit

The record fence rejected the previous pin ("Product sources or lockfile differ
from the pinned main baseline"), so the branch was no longer re-recordable.

Header-only: `baseline` and `recorderSha256` on all 153 goldens — the digest
covers pilot-scenarios.json, whose only edit is that baseline. The re-record is
inert: 0 goldens move observationally and no other field changes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): name the right operation per refuse-after-data probe

Three of the five probes read through optionalSettingsRead, not settingsRead:
repo metadata and resume metadata already did, and workspace context does as of
this branch. The sentence now splits them and states why the split does not move
what the probes record.

Markdown is excluded from recorderSha256, so no re-record.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin the recorder's unhandled-rejection capture

This branch removed the last two goldens that recorded an unhandled-rejection
effect, so nothing exercised unhandled-recording.ts any more: gutting the emit to
`void captureError(error)` leaves all 153 goldens comparing clean. The unit test
drives a detached rejection through the window and asserts both the effect and
the listener restore. README says so where it describes the capture.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-digest the goldens for the new recorder test

Header-only: `recorderSha256` on all 153 goldens, which covers every non-markdown
file under rpc-recording/ and so moves for the added test file. The re-record is
inert: 0 goldens move observationally and no other field changes.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): pin each RPC golden to its own scenario input, not the whole manifest (#20562)

* refactor(mobile): pin each golden to its own scenario input, not the whole manifest

`recorderSha256` covered the recorder directory plus `pilot-scenarios.json`, so every golden's
header was a function of every other family's scenarios. Adding a family for one domain re-digested
all 153 goldens and put a conflict on that line in every domain branch in flight, which serialized
the step-4 fan-out.

Split the two things it conflated. `recorderSha256` now covers the recorder directory only, with
unchanged semantics: a recorder edit still forces a full, deliberate re-record. A new
`scenarioSha256` pins the scenario input that golden was recorded from — every scenario
`runRecording` consumed for it, in order — canonicalised through `captureValue` so an
explicit-undefined param stays distinct from an absent one. `goldenRecording` takes that list
instead of just its first member.

The variants are hashed rather than the base they expand from because they are what was recorded: a
matrix site, its replayed normal result and its partition replies are all visible in them without
the derivation having to be restated. `derived-goldens.ts` is that derivation, extracted from
`family-recordings.test.ts` so the digest and the recording agree by construction — a property test
that restated how a matrix or schedule expands could agree with itself and with nothing else. It
reproduces exactly the 153 golden ids on disk, and the census the suite already ran (every family
matrixed, no stale normal-result inventory entry) now reads off its output.

`golden-header-digest.test.ts` pins the four properties:

- a new family in the manifest moves zero existing goldens' headers, and derives two of its own
- editing one field of `b1` moves exactly `b1` and its family's four matrix goldens — not the two
  other `legacy-inventory` scenarios, and not the goldens that expand from `inventory-lifecycle`
- editing a recorder file still moves every golden's `recorderSha256`, and no `scenarioSha256`
- `recorderSha256` is unchanged by the manifest's contents, and no longer reads the file at all

`GOLDEN_FORMAT_VERSION` goes to 4: a version-3 header has no `scenarioSha256`, and `compareGolden`
walks the expected header's keys, so a reader that accepted one would compare that golden's own
scenarios as though they were unpinned.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the 153 RPC goldens for the split digest

Recorder edit, so every golden needs rewriting. Recorded from the pinned baseline
`16d1ab81d3` with this branch's recorder overlaid, per the README's procedure: main has
moved past the baseline, so recording in place would have failed the product-source fence.

Three header fields moved and nothing else did:

- `recorderSha256` 6a12160a87… -> 2fda557f58…, one value across all 153 files
- `scenarioSha256` added, 153 distinct values
- `goldenFormatVersion` 3 -> 4

No observation, checkpoint, value-pool entry, `baseline`, `lockfileSha256` or `platform` changed:

    git diff -U0 -- mobile/rpc-foundation | grep -E '^[+-]' | grep -vE '^(\+\+\+|---)' \
      | grep -vcE 'recorderSha256|scenarioSha256|goldenFormatVersion'
    0

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): certify the pilot goldens from the derivation that digests them

`pilot-recordings.test.ts` restated `[scenario]` instead of consuming `pilotGoldens`, so the claim
that a golden's `scenarioSha256` is a function of the same derivation that records the file held
only for the 75 family goldens: dropping a scenario from `pilotGoldens` left the whole suite green
and put that golden outside the header oracle. The pilot suite now iterates `pilotGoldens`, and a
census fails if the derivation and the goldens directory disagree in either direction — which also
closes the pre-existing orphan-golden gap.

Also from review: pin the cross-sibling replay that hashing the generated variants buys (a matrix
golden's `normal` partition replays a sibling's recorded reply, so editing that sibling must move
it); state the real reason for the format bump, which is the diagnosis a version check gives rather
than a rejection the byte compare already made; drop the fourth property test, which re-proved what
tests 1 and 2 and `recording-runner`'s digest test already fail on; and drop a guard in
`scenarioSha256` that its only caller reaches after an identical one.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the 153 RPC goldens for the review edits

Recorder files changed, so `recorderSha256` moved. Recorded from the pinned baseline with this
branch's recorder laid over it, per the README's migration-branch procedure. That one header field
is the only line that moved in all 153 files: `scenarioSha256` and `goldenFormatVersion` are
unchanged, and no observation moved.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): correct the recording suite's test count

Round-2 review: the README said 200 tests; the suite is 209 after the five
added here. Markdown is outside recorderSha256, so no golden moves.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the 153 goldens on the merged baseline

Four header fields moved and nothing else. Proven against origin/main: every
changed line in all 153 files is one of these, and the file set is unchanged.

- `recorderSha256` 70aa6f59e0 -> 58a461dbc9: this branch's recorder, and it now
  digests only the recorder directory, not the scenario manifest.
- `scenarioSha256` added, 153 distinct values over 153 goldens.
- `goldenFormatVersion` 3 -> 4 for that added field.
- `baseline` 5ec0b2698f -> e53f1557e1, the merge's repoint onto the real main
  commit. #20563's value was a branch commit the squash left unreachable, so the
  record fence's `git diff <baseline>` could not resolve it.

No checkpoint, value pool, effect or settlement byte moved, so main's recorded
behaviour is carried over intact.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* docs(mobile): account for main's added recorder test in the suite count

The merge brought in `unhandled-recording.test.ts`, one test, so the recording
suite is 210 rather than the 209 this branch documented. Markdown is excluded
from `recorderSha256`, so no golden moves.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(native-chat): stop a bounded tail read from moving the chat cursor past unapplied rows (#20581)

* fix(native-chat): stop a bounded tail read from moving the chat cursor past unapplied rows

A structured chat pane could latch "Working for N" forever after the agent had
finished, showing the send arrow rather than Stop, while the sidebar and
`worktree ps` correctly read idle.

The client replica has one position (`state.cursor`) and one body. Two
operations keep those consistent: replace (both from one host snapshot) and
append (rows contiguous with the cursor). The `tail-page` branch was a third
thing: it took the cursor from the journal head, the items from a bounded page
(200 items, byte-capped), then merged retained client submissions over the
page's. Under continuous journal writes the client is always slightly behind,
so the branch ran on every window focus and on every pane re-activation. When
more than a page of rows had landed since a send, that send's user item fell
off the page, its submission was not carried, the retained `pending` survived,
and the cursor jumped past the dispatch-acceptance row. Nothing re-sends it: a
batch carries only touched items and that submission is never touched again.

Delete the third operation rather than guard it. A live subscription is now the
only thing that moves the cursor, and `subscribe({ cursor })` already replays
exactly the missed rows.

- remove the window `focus` listener and the owner/transport `refresh` contract
- skip warm hydration: a retained owner subscribes at its applied cursor
- cold hydration keeps its history read, applied as the existing `snapshot`
  (replace) event rather than `tail-page`
- delete the `tail-page` action and its reducer branch
- delete `resumeCursor` and `shouldAdvanceStructuredResumeCursor`; two cursors
  with two advancement rules were how position and body drifted apart

`older-page`/`loadOlder`, the unattached-refusal grace, generation guards and
the coalescer are unchanged. No host, wire or schema change.

Also fixes a second cost of the same branch: focus during a busy turn discarded
paged-in older items, shrinking the transcript to one bounded page mid-turn.

* fix(native-chat): preserve unavailable mixed-version session fences

* refactor(mobile): send the task workspace-creation domain through typed RpcOperations (#20568)

* test(mobile): record main's task workspace-creation RPC behaviour before migrating it

28 scenarios over nine task senders, recorded from main so the step-4 migration of
the workspace-creation half of src/tasks/ has a frozen answer to compare against.
Four senders mount as plain exported functions; three are model-chained hooks
mounted the way the settings adapters mount theirs.

The 153 existing goldens change header-only (`baseline`, `recorderSha256`): any new
scenario re-digests the recorder, and the pinned baseline had drifted from main
because the source-control migration landed. Content is byte-identical on all 153 —
verified field-by-field against HEAD.

`operation-module-loader.ts` now shares src/transport/rpc-delivery-ambiguity.ts with
mounted modules instead of evaluating a second copy. The mark is a WeakSet keyed on
the rejection object, so the copy the loader built had an empty registry and every
delivery-unknown rejection read as a definite failure inside the operation under
test — worktree.create's whole replay path was unreachable. With one registry,
`tw-create-retry-ambiguous-after-drop` records the create still pending at the
reconnect wait and abandoning at exactly 20000 ms, while the unstamped-create
scenario records the same rejection surfacing at 0 ms. No existing golden moves:
no other mounted module consumes the mark.

`task-preferences-optimistic` is re-anchored above the send rather than across it,
so migrating this file does not have to move the anchor. It still kills, and for
the same reason: the preset the screen shows no longer follows the tap.

Scenarios deliberately pin the empty-message refusals (`*-refused-empty-message`,
`*-empty-message`), because a refusal with no message falls back to the screen's
copy while a transport error with no message does not, and the two paths are easy
to collapse when a call site moves behind an acceptance policy.

Goldens: 153 -> 201, 2.9M -> 3.7M.

* test(mobile): format the recording manifest and re-digest the goldens

`oxfmt --check` from mobile/ collapses a one-element `sites` array in each new
scenario. The JSON value is unchanged — verified by comparing both files parsed
and key-sorted — but the manifest is inside `recorderSha256`, so all 201 goldens
carry a new digest. Every other field, header and observation alike, is
byte-identical.

Re-recorded in a separate worktree at the previous commit so the goldens stay
attributable to main's product source rather than to the migration that follows.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): separate the goldens from the migration, and re-digest

The previous commit accidentally carried the product migration alongside the
manifest format, which both broke the commit that is supposed to prove parity and
left the suite red: the digest was recorded without a comment move that a lint fix
had made inside the adapter, so all 201 goldens failed their `recorderSha256`
header.

This backs the product half straight out again — the next commit re-applies it
byte-for-byte — and re-records from the pinned baseline in a separate worktree
carrying this branch's recorder, per the procedure in the recording README. Every
field except `recorderSha256` is byte-identical to the previous commit's goldens on
all 201 files, so no observation moved in either direction. The suite is green here
with main's product source, which is what makes the next commit's "no golden
changed" claim mean something.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): send the task workspace-creation domain through typed RpcOperations

12 of src/tasks/'s 37 raw-port files now send through a declared operation instead of
the raw request port: 36 references to 0, leaving 25 files and 73 references for the
provider item/detail/mutation half. No golden moved — `git show --stat` on this commit
touches nothing under mobile/rpc-foundation/, which is the parity claim.

Twenty-two operations over twenty methods, in four modules named for what they send:
workspace create (create, PR/MR base resolution, create-time capabilities), workspace
source (SSH connect/state, agent detection, repo hooks, sparse presets, ref search),
task runtime (status, ui.get/ui.set, preflight, Linear status, settings.update) and the
Smart picker's provider reads.

Two methods carry two policies each, and both pairs are named. `status.get`: the Tasks
screen cannot hydrate without it and surfaces the host's message, while create-time
capability probing degrades to "no capabilities" and creates anyway — so one throws on
refusal and one skips. `ui.set`: two sites await it, one is fire-and-forget and never
interprets the reply at all. Both pairs share one reader, so no method has two readers.
No new acceptance policy.

worktree.create keeps its delivery-unknown contract. `request` returns the transport
promise itself, so the retry loop catches the object the transport marked; two new tests
assert `toBe(marked)` in one direction and that an unmarked rejection stays unmarked in
the other, because a mark added on the way out would replay a create the host never
received. `tw-create-retry-ambiguous-after-drop` records the create still pending at the
reconnect wait and abandoning at exactly 20000 ms.

Three sites still read the raw refusal envelope before interpreting, because the code or
the message decides the route and no acceptance policy carries either through: the create
retry needs the message for `isRetryableWorktreeCreateConflict`, and the paste lookup
needs `method_not_found` to retire the slug probe host-wide. Both are documented at the
site.

The hydration barrier keeps raw requests inside its `Promise.all`. main's group rejects as
soon as one leg rejects; `startRpcOperation` + `interpretAtRpcBarrier` would wait for the
slowest peer and let a later policy surface a different error. Interpretation stays after
the `stale` guard, where it was.

`WorkspaceCreateParams` is now `RpcSendParams<'worktree.create'>` rather than
`Record<string, unknown>`, which types the builder and the operation together; every field
the three builders already sent typechecks against the host schema unchanged.
`RpcSendArguments` now also makes params optional for a method whose params type has no
required field, because `preflight.check` is such a method and main sent it none —
requiring `{}` would have put a new object on the wire.

The Mobile Tasks source-parity hashes move for the same reason bound settings requests
moved them: the method string and the envelope read leave the screen. The signature diff
is evidence rather than a re-pin — `semantics` is a pure deletion of 22 `rpc:` call
signatures and 22 method literals with nothing added, statement/declaration/render/style
counts are unchanged, and render tokens, styles and declarations are byte-identical.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): split the task workspace adapters at the sender/hook seam

The single adapter file reached 344 lines against mobile's 300-line limit. CI lints
every file, so this is red there even though the changed-code gate does not report it.
Split along the seam the recording README already draws: exported async senders that
take a client and need no React host, and the drawer's three model-chained hooks.
No adapter body changed.

Both files are inside `recorderSha256`, so all 201 goldens carry a new digest. Every
other field is byte-identical, verified file by file. Re-recorded from the pinned
baseline in a separate worktree carrying this branch's recorder, so the goldens stay
attributable to main's product source.

* refactor(mobile): give the one-key unchecked reader a name

Four readers were the same three lines: read one property off the reply, wrap
it unchecked. `rpcUncheckedMemberReader` is the one-key sibling of the existing
`rpcUncheckedPayloadReader`, so the annotation and the closure go away at each
site. The pilot's `commitCompareEntriesReader` is converted too, so the helper
has no longhand twin left to copy from.

No behaviour change: the helper composes the same `rpcReadUnchecked` over
`rpcPayloadMember`, including the property-read exception on a null result.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): record the local arm of workspace agent detection

`preflight.detectAgents` was the one migrated operation with no recorded
coverage: the ssh adapter hardcoded `connectionId: 'ssh-1'`, so the detection
effect's ternary only ever took the remote arm and the local call site could be
repointed at another method without a golden noticing.

The adapter now takes the connectionId as a parameter and registers twice;
`tasks.workspace-ssh-local` mounts the same hook with no connection, which is
the only difference the effect branches on. Recorded at the pinned baseline
with this branch's recorder laid over it, so the new golden is main's
behaviour and the migrated code has to reproduce it — it does.

Goldens: two added (`tw-workspace-ssh-local-agents` and its reply matrix). The
other 201 changed on `recorderSha256` only, because the adapter edit moves the
recorder digest every golden pins.

* test(mobile): drive workspace create and the Linear list to a recorded wire

Two operations passed a policy swap unnoticed, both because no golden reached
their acceptance branch.

`worktree.create`: the create hook's fixture resolved setup to a prompt, so all
three settings.task-workspace scenarios stopped before the request and the only
consumer that hands a refusal to interpret was never recorded. The adapter now
takes the setup resolution as a parameter and registers a second family that
resolves it, so createWorkspace runs to the wire. Two scenarios: a Linear item
that creates directly, and a GitHub pull request that resolves its base first,
which also puts this hook's built params — start point, generated display name,
agent launch fields — in a golden for the first time. The existing prompt
family is untouched, so its recordings still pin that branch.

`linear.listIssues`: it appeared only in a non-base scenario, and the matrix
reads the family base, so the family had no partition for it. The base now
lists assigned issues after searching.

Goldens: five added. Five moved beyond the digest, all derived from the
smart-search base that gained the list leg. The other 198 changed on
`recorderSha256` only. Recorded at the pinned baseline with this branch's
recorder laid over it, so every new golden is main's behaviour.

* test(mobile): drop the unreachable unmount branches from the task adapters

Nothing dispatches `unmount` to these three adapters: the only producer is
`lifecycleSchedules`, driven from a hardcoded five-id list that names no
task-workspace family, and it pushes a `remount` right after, which these
adapters would throw on. The branch read as lifecycle coverage that was never
wired up. `dispose: hook.unmount` already tears the mount down.

Goldens re-recorded at the pinned baseline because the recorder digest moved;
`recorderSha256` is the only line that changed in all 208.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the goldens at main's post-squash baseline

Recorded from a detached checkout of e53f1557e1 (main's unmigrated
product code) with this branch's recorder laid over it, so the parity
claim stays non-circular.

- `baseline` repinned to e53f1557e1 on all 208 goldens; main pinned
  5ec0b2698f, a pre-squash branch commit not reachable from main.
- `recorderSha256` moved on all 208 because this branch's adapters are
  in the whole-manifest digest.
- 55 task-workspace goldens re-recorded at the new baseline.
- No other line in any of main's 153 goldens changed.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): re-record the goldens under #20562's per-scenario digest

Baseline repinned to 50e752fc66 and all 208 goldens recorded from that
commit's unmigrated product tree with this branch's recorder laid over it.
recorderSha256 moves on every golden because the task-workspace adapters
live in the recorder directory. scenarioSha256 does not move on any of
main's 153: the manifest only adds 31 scenarios and edits none, which is
the property #20562 was built to give.

* feat(ai-vault-search): construct the session search indexer in the scanner service behind a setting (#20516)

* feat(ai-vault-search): persist agent-session search consent and retention

Two booleans and nothing else: `enabled` and `historyDays`, off by default
because building the index reads every transcript on the machine. No `paused` --
the PR 3 indexer is immutable, so every change is close-and-construct.

The settings IPC normalizes a write like every other field and hands the change
to the index; there is no UI for it until PR 8.

* feat(ai-vault-search): hold one indexer and engine pair per host

The object that owns a host's live index and the three recipes that change it.
The indexer is immutable, so a settings change is close-and-construct, disabling
is close with no replacement, and clearing is close, remove the database,
construct. The new instance's first sweep purges a narrowed window and admits a
widened one, so neither needs a code path.

The database sits beside the scanner's parse cache, one file per host. A runtime
with no node:sqlite can hold no index at all, which the Node 18 floor on orcad
and the relay makes a real case rather than a hypothetical one.

* feat(ai-vault): let the scanner child own the session search index

The transcript reader runs in that child, so the index consumer has to as well:
one read serves both the session list and the index. Three request operations
(search, status, reconcile) and one fire-and-forget settings message carry
everything a parent needs; main never opens the database file.

The init frame becomes a factory because it is read at every spawn, so a
respawned child sees current consent rather than the first frame's. A child
holding a running index is never idle from the parent's side, so idle retirement
is suppressed while the index is on -- retiring it would stop the reconcile loop
until some later scan happened to respawn one.

Both files this lands in were already at the max-lines ceiling, so three
collaborators move to where they belong rather than being disabled around: the
invalidation deadline into the class that owns invalidations, call cancellation
and the start requeue into the call-state module, and orcad's flag parsing into
its own file.

* feat(ai-vault-search): register a search service on every host that answers

Without a registered service a host answers no-service, which means "this host
does not have the feature" rather than "the index is off". All three hosts now
answer the second thing.

The desktop forwards to the scanner child. orcad and the SSH relay daemon have
no such child -- orcad ships only the watcher and daemon entries, and the relay's
AI Vault sidecar runs the remote scanner, which publishes nothing to the
transcript channel -- so on those two the index lives in the process that would
drive its reads, gated on a runtime that has node:sqlite at all.

The relay registers with consent off and no way to turn it on: nothing carries a
setting to a remote host yet. That is the honest state, and it is still worth
registering, because it is what tells a client the difference between off and
too old.

* test(ai-vault-search): price a warm pass over five thousand transcripts

The number the reconcile interval will be revisited against, measured rather
than argued: a warm sweep stats every file under every root, a warm cycle stats
the newest N per agent, and neither reads what the index already holds. It does
not tune the interval.

* fix(ai-vault-search): answer the casting gate without assertions

main's new type-assertion rule reaches every file this branch touches. All nine
sites drop the cast rather than carry a SAFETY: rationale: the operation guard
narrows with `in`, the sqlite probe narrows the builtin it loads, the child test
keeps the discriminated reply instead of widening it, and the settings resolver
takes `unknown` -- which is what it really reads, since a persisted profile can
hold a value no version of this code wrote.

* fix(ai-vault-search): let a refreshed scan root reach the live index

The parent re-resolves scan roots before every policy push, precisely so a
WSL distro or extra Codex home that appeared since the child spawned enters
the window. The child forwarded only the settings to a live instance and used
the roots solely in its `??=` initializer, so those roots were dropped for the
child's lifetime.

The indexer stays immutable: a structurally different root set closes the pair
and constructs a new one, the same way a changed databasePath already does.
Compare via `sameSessionSearchRoots` rather than a plain JSON compare, because
nothing fixes the key order two producers write; lists are sorted too, since
the indexer walks every root and a re-enumeration that reorders is not a
change. An unchanged set still never restarts a running index.

The orcad and relay in-process hosts resolve roots once at install and never
re-apply, so they have no such seam.

* fix(ai-vault): restart the scanner child the index is holding

Three review items.

The hold keeps a child alive for the index, but only a queued call ever
started one: `pump()` skipped a hold with an empty queue, so an idle indexing
child that crashed, or an `ensureChild()` that failed at start, left indexing
stopped until an unrelated request happened to arrive. `pump()` now starts the
child the hold requires, which is also the restart callback the fault policy
already schedules, so the existing delay and circuit bound the retry exactly as
they bound a queued call's start. `updateSessionSearch` goes through the same
seam instead of its own `ensureChild` call.

A search registers no AbortController, so a cancel sent for a search id was
added to the `cancelled` set and never consumed. Nothing can reach that today
-- no caller passes a signal and the child answers in milliseconds -- so this
is only a leak of ids: consume it when the search settles.

The orcad argument doc claimed a `--`-prefixed value stays a flag. The parser
takes the next token regardless, and orcad-launch-contract.test.ts pins that,
so the doc is what was wrong. Behaviour is unchanged.

* Bump mobile app.json to 0.0.50 (#20661)

* fix(native-chat): bound a dispatch reason before it reaches the journal row (#20654)

`AgentJournalSubmission.reason` was the only unbounded field written by
Orca's own code. `dispatchSafely` sets it from the adapter's raw
`error.message` and `journalDispatchRowBuilder` stored it verbatim, so a
provider error carrying a multi-megabyte body -- a stringified HTTP error
payload, say -- reached the row at whatever length the provider sent, and
stayed on disk at that size for the life of the journal.

It now goes through `boundInlineText` with the journal's existing inline
limit, the same idiom already applied to arbitrary text on the Claude and
Codex translation paths.

The bound must stay head-preserving. `dispatchRejectionWasTransportWriteFailure`
prefix-matches the value, and `dispatchRejectionReasonIsInternal` builds on
it, so a bound that kept the tail instead would stop classifying a clipped
transport failure and render raw provider text to the user as an ordinary
rejection notice. A test pins that, and clipping stays marked rather than
silent so a truncated reason is never presented as the provider's complete
explanation.

Rows written before this keep their full text, so readers can still meet an
unbounded reason.

* fix(native-chat): keep a resumed transcript pinned to its end (#20651)

* fix(native-chat): keep a resumed transcript pinned to its end

Follow state was recomputed from distance on every scroll event, and a pin writes scrollTop itself, so the browser reports that write back as a scroll event a frame later. Once a resumed session's later history pages and settling row heights had moved the end away from it, that echoed event read as the reader leaving and the pin was dropped for good, stranding them mid-transcript. Measured in Chromium: a pin followed by same-task growth delivers a scroll event reading 2000px from the bottom, indistinguishable from a reader scrolling up.

Pins now go through the virtualizer instead of writing scrollTop directly, so both parties resolve the end through the same maximum rather than holding rival definitions of it. Whether the reader left is now a question of provenance rather than distance: an offset this transcript wrote is never a departure. The end test reads live geometry, because the virtualizer's own isAtEnd subtracts a cached offset from a live maximum and this handler runs before that cache is refreshed. overflow-anchor:none stops the engine moving scrollTop under a settling row, which would otherwise look like the reader.

This does not make ownership singular. The virtualizer still writes autonomously from several paths and those writes stay unattributed; what this removes is the rival definition of the end, not the second writer.

* test: extract shared toast options type for source control tests

Consolidate duplicate `ToastOptions` type definitions across three test files into a single `SourceControlToastTestOptions` type, reducing duplication and improving consistency.

* fix(source-control): separate refresh failures from mutation failures

Post-mutation refresh failures are logged separately, not surfaced as toasts
(mutation already succeeded). Use preventDefault() on retry to prevent sonner's
auto-dismiss from swallowing re-raised failures. Consolidate stage/unstage into
a shared handler to reduce duplication.

* fix(source-control): only dismiss entry failures from the owning worktre

Track which worktree owns the shared entry-failure toast slot. When a mutation
completes, only dismiss the slot if the completing worktree is the one that
raised the failure — a slow retry in one worktree should not erase a failure
another worktree has since raised into the slot.

* Remove entry mutation status refresh helper

Inlined into the caller during consolidation of failure handling and
tracking in the source-control entry mutations flow.

Call refreshActiveGitStatusAfterMutation directly instead of through the

* fix(store): stop two no-op writes from re-running every selector in the app (#20641)

* fix(store): stop two no-op writes from re-running every selector in the app

zustand bails out of a `set` only when `Object.is(next, state)`. Two updaters that
mean "nothing changed" hand it a fresh reference instead:

- `setWorkspacePortScanRefreshing` wrote unconditionally — the one action in its
  file that did; its four siblings all early-return `state`.
- `applyGitHubPRRefreshEvent` ended its no-op branch with `: {}`, and
  `Object.assign({}, state, {})` reproduces every field unchanged while still
  notifying. ~20 sibling sites in the same store already use `return state`.

Both rebuild the root and wake every subscribed selector (~2.2k per the listener
census). Renders are unaffected — the selection is unchanged — so the cost is
wasted selector evaluation, not commit pressure. The resulting state looks
identical either way, which is why it goes unnoticed; both tests therefore count
subscriber notifications rather than asserting state.

* fix(ci): stop hourly versions dropping below a tagged or already-shipped build

Hourly/daily/adhoc based their X.Y.Z on GitHub releases, not git tags. When
v1.4.202 was tagged and then its GitHub release vanished, the next hourlies
shipped as 1.4.202-hourly — below both stable 1.4.202 and the 1.4.203-hourly
builds already installed, so electron-updater stopped offering updates.

* fix(codex): settle a structured send on admission, and stop minting a colliding identity (#20138)

* 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…
