* fix(codex): stop blocking the main thread on trust grants (#16441)

Codex hook trust was granted by blocking the Electron main thread on
`spawnSync` of a bundled ELECTRON_RUN_AS_NODE entry for the whole
app-server deadline: 15s native, 35s WSL, ~45s on the real-home path
(rebase inspect + repair + grant). Cold start and every Codex pane
launch showed "Not Responding"; the reported event-loop gap was
15,049 ms.

The subprocess only ever existed to donate an event loop to a
deliberately blocked parent — `runCodexHookTrustGrantSession` was
already the real async implementation. Make the callers async and the
fork is unnecessary, so the bridge, the forked entry and its envelope
are deleted along with their build/knip/tsconfig registrations. The CLI
`agent hooks prepare-codex` handler is already async, so it awaits the
in-process session and saves a process spawn per managed-home shell.

`resolveCodexTrustGrantHost` is async too; the WSL identity probe moves
from `execFileSync` to `runProcess`, dropping that file from the
child-process import allowlist. Status reads keep a synchronous
native-only stamp path.

Two invariants that held only because the lane blocked:

- Overlapping capability probes were impossible by construction.
  `GitCapabilityCache`'s dedupe engine is extracted to a shared
  `CapabilityProbeCache` and `CodexAppServerCapabilityCache` now
  inherits it, so concurrent launches against a cold host share one
  app-server session instead of one each.
- Two grants on one `config.toml` could not interleave capture and
  restore. A reentrant per-file lane now serializes the whole install
  sequence (managed, WSL runtime, real-home ensure, legacy sweep) and
  the grant and rebase inside it.

Cold-start work moves off the critical path: retained-home
reconciliation (N sequential sessions) is fire-and-forget behind the
daemon provider, and the startup real-home ensure chains into managed
hook reconciliation instead of blocking app init.

Every preserved semantic is unchanged: never throws, the
ORCA_DISABLE_CODEX_TRUST_RPC kill switch, ledger hits, backfill-pending
and cooldown fallbacks, config rollback on every failure path,
pre-grant self-computed trust removal, the verify-failure taxonomy,
diagnostics and telemetry.

* fix(codex): widen the trust-config lane to every config.toml writer

Review follow-ups on #16441's async trust grant:

- `markCodexProjectTrusted` now runs inside the runtime+system config.toml
  lanes, so a project-trust write can no longer land inside a hook grant's
  capture->restore window and be silently reverted. Its callers await it.
- `install`/`refreshRuntimeUserHooks`/`remove` hold the system config.toml
  lane as well as the runtime one — they promote approvals into
  ~/.codex/config.toml and mirror it back. Lock order is runtime-before-system
  everywhere.
- The real-home ensure chain resumes after a rejection instead of returning
  the same rejected promise to every later pane launch, and resolving the real
  home is now inside the module's never-throws boundary.
- `buildSpawnEnv` awaits inside a cancelable pending-spawn registration, so
  shutdown during the (now long) env build stops the PTY from launching.
  `prepareLocalPtySpawn` generalizes into `awaitCancelableLocalPtySpawn`.
- CapabilityProbeCache drops the test-only `nowMs` passthrough; its probe
  backstop comment now describes what it actually guards.
- Preflight is a plain async function; the trust dispatch in orca-runtime
  collapses into one `markWorkspaceTrustedForAgent`.

* test(codex): exercise the trust-config lane under real concurrency

The async grant makes two pane launches overlap for the first time. These
drive the real modules end to end on real files: a rollback swallowing a
sibling's grant, a markCodexProjectTrusted write landing inside a capture
-> restore window, shared capability-probe dedupe on a cold host, the
host-scoped transient cooldown, and reentrancy from inside an installer.

Each was verified to fail against a deliberately broken implementation
(lane removed, dedupe disabled, cooldown made global, reentrancy pass-
through disabled).

* test(codex): stop hook-service suites spawning the developer's real codex

The forked grant bundle never existed under vitest, so the RPC lane was
unreachable in tests on main. Running it in-process makes these suites
spawn a real `codex app-server` when one is installed: 38 spawns and two
failures in hook-service-runtime-trust-repair on a machine with codex,
green in CI where there is none. Stand in for the missing binary so both
environments exercise the same fallback lane.

* docs(codex): scope the trust-RPC kill switch comment to what it actually gates

The comment read as though the flag forces the fallback lane everywhere. It
gates the managed grant only: the real-home rebase still runs its own
inspect/repair app-server sessions when Orca's insertion shifts a user's hook
positions, and never reads the flag.

Verified by exercise, not by reading — with the flag set, both
inspect-user-hook-trust and repair-user-hook-trust still ran. Pre-existing:
main has no check there either, it just blocked the main thread while doing it.

Widening the flag to cover the rebase is a follow-up; this only stops the
comment promising something the constant does not do.

OrcaWinandOrcaWin 4ec6bbf588 Kill hung WSL transcript filesystem operations via child process with route quarantine (#15381)
* fix(native-chat): kill hung WSL operations via child process

Stalled UNC file operations hold libuv permits even after the gate
timeout expires, blocking Chat tab recovery. Two stalled operations
fill both permits and freeze all WSL access until restart.

Fork file I/O for UNC paths into a separate child process. On deadline
expiry, kill the process to force the hung syscall to exit. This frees
the permit for the affected tab's next read. Temporarily quarantine the
stalled route to avoid retry storms.

* chore: drop internal review artifact from the repo root

* fix(native-chat): harden the WSL transcript fs sidecar

Review follow-ups on the sidecar isolation change:

- Only the deadline may abort running gate work. The sole waiter's
  same-duration timeout fired first, killed healthy children on caller
  abandonment, and settled the task before the deadline could quarantine
  a stalled route - leaving the back-off dead for every dedupe:false op.
- Resolve the fork entry from out/main/chunks too: the resolver compiles
  into a shared chunk, and the scanner service child has no
  process.resourcesPath, so packaged WSL vault scans threw entry-not-found
  (masked as an empty tree).
- Allowlist the fork env instead of spreading process.env; ambient
  NODE_OPTIONS would halt or --require code into every child.
- Wrap transport faults (spawn failure, child death) in
  WslTranscriptFsError('unavailable') so discovery reports them as scan
  issues instead of misreading them as missing paths or empty trees.
- Gate the vitest in-process fallback on the vitest worker global so a
  leaked VITEST=true cannot revert production to in-process UNC syscalls.
- Reap idle sidecar processes after 60s instead of holding them for the
  app session.
- Split 'open' into its own protocol union member so the reusable-call
  Exclude actually strips it from the pooled-process API.
- Guard kill('SIGKILL') against the teardown race where an exiting child
  emits an unlistened 'error', and dispatch reads by handle kind before
  path spelling.

* fix(native-chat): probe stalled WSL routes instead of a fixed quarantine

Remaining review follow-ups:

- Escalating route quarantine: first strike lifts after 5s so a distro
  that was cold-booting when its op hit the deadline recovers on the
  next poll (~35s total instead of ~90s); repeat stalls double the
  back-off toward the prior 2x-timeout cap, and any settle the deadline
  did not force clears the strikes. Queued same-route tasks fail fast
  at quarantine instead of stranding one waiter deadline per file in
  sequential scans.
- Single request implementation: the vitest in-process fallback now runs
  the child's own dispatcher (WslTranscriptFsProcessOperations + decode),
  so unit suites exercise exactly what the forked process executes and
  the per-call-site fallback closures are gone. Dirent fixtures gained
  the full kind-flag set the serializer reads.
- Dropped the production-dead per-route close queue; UNC FileHandles
  (test fallback only) mirror the process-handle close contract.
- Error class, messages, and factories move to wsl-transcript-fs-error
  (re-exported from the gate) to keep the gate under the lines budget.

* fix(native-chat): harden WSL transcript fs with route quarantine strike

Extract quarantine logic into a dedicated module with strike decay: stalls older
than 5 minutes restart from base back-off, and concurrent-lane timeouts count as
one incident. Allow joining live in-flight tasks on quarantined routes (they cost
no new I/O). Preserve quarantine across transport faults (child death). Handle
file shrinking during tail reads by detecting short reads and returning empty.
Defer file closes that arrive mid-read instead of refusing, preventing slot
leaks. Separate process slot and boundary-finding concerns into focused modules.

* fix(native-chat): enforce route quarantine windows and isolate lanes per

A late result arriving after the deadline was incorrectly lifting the route
quarantine, allowing subsequent work to start before the back-off period
expired. Now late results are correctly recognized as stale and never cut
the quarantine short.

Process work is now isolated per (route, priority) lane so a scan stall
cannot block exact reads on the same distro. Each lane gets its own client
and process pool; late results and handle faults stay scoped to their lane.

Tests now fake performance.now() alongside timers (the quarantine clock
depends on it) and wait for the full back-off window to expire rather than
advancing by 0. Gate state is reset between test cases since late releases
never lift the quarantine.

Jinjing 4c69e45552 Strengthen plain-node-entry-guard with entry name validation (#12761)
* Strengthen plain-node-entry-guard with entry name validation

- Add buildStart hook to validate guarded entry names exist in rollup
  inputs, preventing stale names from silently stopping guards
- Extend electron require detection to subpaths (electron/main, etc)
- Improve smoke test signal/exit handling and use constants
- Add comprehensive tests for entry validation and new behaviors

* Add SIGKILL escalation to plain-node-entry-guard timeout

Switch from spawnSync to async spawn to properly handle daemons that trap
SIGTERM. spawnSync's timeout only sends the signal and waits, so a daemon
that ignores SIGTERM causes the build to hang. The new runDaemonEntry
function escalates to SIGKILL after a grace period to enforce the deadline.
Configurable timeouts and grace periods via SmokeTimings type; closeBundle
hook becomes async to support the change.
