fix(service): keep health probes responsive under contention - #8456
A local proxy could keep serving generations while its CLI reported it offline: /healthz missed the unchanged 750 ms probe deadline under contention. Fix two additional causes alongside the Keychain and usage-scanner work in #8337, #8450 and #8455.
macOS launch agents now declare ProcessType=Interactive. The default launchd daemon resource class throttles CPU and I/O even though Codex and dashboard responsiveness depend on this local proxy. In the on-host diagnosis the daemon ran at priority 20; registering the interactive definition changed it to 31. Adaptive is unsuitable because the proxy does not use XPC transactions. Install/repair upgrades a legacy definition once; later repairs stay idempotent.
withCredentialPublicationFenceAsync no longer invokes SQLite's synchronous ten-second busy wait. It makes nonwaiting attempts and yields between SQLITE_BUSY retries within the existing monotonic ten-second budget. The callback still starts only after exclusive acquisition, nested holders remain reentrant, errors fail closed, and the original SQLite error is retained on expiration. The synchronous API retains its existing contract.
Verified reloads of changed launchd definitions require an accepted bootstrap as well as a matching command. With readable launchd state, a refused policy-only migration retries transient teardown, then reports failure, attempts to restore the previous plist and retains any backup; it cannot silently become a no-op on the next repair. Three regressions cover refusal, rollback and successful recovery. The policy-only migration preserves the normalized installed PATH even when repair runs with a narrower PATH, including removal of obsolete fnm entries; two additional regressions cover migration and idempotent later repair. If the final launchd probe is unreadable, no further eviction or restoration is attempted: an accepted bootstrap warns of an unverified reload, and a refused bootstrap throws while retaining the new plist and any backup for manual verification.
Unconfirmed launchd definitions remain pending across repair invocations, including after a token change. An owner-only metadata marker is written before publishing new bytes. Pending repairs preserve any original recovery copy successfully created, require an accepted bootstrap plus matching probe, and cannot use a matching command or cached-definition kickstart as confirmation. A readable failure attempts to restore the original backup when available; an unknown initial probe refuses before definition writes, and an unknown probe after bootstrap causes no additional eviction or rollback. Successful verification clears the marker, and uninstall removes it. Five new regressions cover both accepted/refused unverified loads, both token cases, and persisted state from a prior invocation.
A fresh install disregards pending metadata without its plist and removes orphaned recovery files before publishing new bytes, so neither the first nor a later failed repair can restore a stale definition. Full uninstall removes the plist and both recovery files even when the plist is already absent. Cleanup of recovery files during a new installation, removal of a pending marker and uninstall cleanup ignore only ENOENT; other errors in these steps prevent install-state deletion. Removing the old .prev backup after a verified repair writes state remains best effort and does not change its success. Successful overlapping repair can still persist install state if its marker was already removed. Lifecycle guidance in English and all seven translations now distinguishes readable failure/restore attempts, unknown-state outcomes and inspection, checkable initial probes/GUI sessions, and best-effort backup creation.
Long credential-fence contention backs off from 25 ms to at most 100 ms, capped by the same remaining ten-second budget. A fourth regression bounds retry churn without extending the deadline.
Add separate-process HTTP regressions with a real SQLite reader/writer holding the fence. The parent releases the lock only after the health request succeeds, proving the response was sent while the write was still excluded. Add deadline checks before/after yielding, permanent-error and cleanup coverage, and launchd install/repair regressions. A further real-server regression changes an encrypted native profile through the production management API and default NativeProfileManager writer, probing production /healthz while a peer holds the publication fence. Maintain migration guidance in all seven lifecycle translations. Update test inventory and public/architecture docs.
Security review required before merge: this changes credential-publication lock acquisition. In particular, review exclusion, reentrance, error classification and deadline behavior. No credential values, generation formats, attestation rules or incoming-auth policy are changed. Observer events are not coalesced and no coverage validation is skipped.
Verification
Maintainer verification at 20a877fe2 (author branch merged with dev23bbe8ea7, plus maintainer commits a7943bea2 and 20a877fe2 from independent technical and security reviews):
Four new regressions fail on the previous head and pass here: a refused repair leaves a job still serving the expected command in place; a failed backup write and an unreadable installed plist both leave no older .plist.prev behind a pending repair; the async fence acquires a lock released during its final wait.
bun scripts/test.ts over the fence, local-credential, uninstall, native-profile (incl. healthz), launchd-repair, service-definition, pinned-homes, layout and file-size-ratchet files: 328 pass, 0 fail.
bun run typecheck (2,418 files), bun run structure:check, bun run privacy:scan: pass.
bun scripts/test.ts --changed=origin/dev at a7943bea2: 53,514 tests, 47 fail; the 18 failing files are real Node/npm launcher, Codex CLI update, retained-sync and link e2e tests that fail the same way on dev on this host (5 s timeouts, missing ocx-child binary).
NOT RUN: real launchctl against a live job (all launchd coverage is mocked); Windows/macOS full CI (batched dev dispatch).
Author verification (earlier heads):
Current documentation-only validation at 8bb3ebb17ff2086c731406ed4e9b5e9be404ba8b, based on dev081f6416 (six commits behind observed devef605e43, within the readiness tolerance):
The nine changed paths are the English lifecycle page, its seven translations and the architecture contract. Runtime and test sources are unchanged. The guidance distinguishes refusal before a new plist/backup is written from an unknown probe after bootstrap; strict cleanup errors are limited to new-install recovery, pending markers and uninstall. Removing .prev after verified repair writes install state remains best effort.
bun run typecheck — no errors in 2,409 files. bun run privacy:scan, bun run structure:check and git diff --check pass.
cd docs-site && bun install --frozen-lockfile && bun run build — pass; 665 pages and 96,089 internal links checked.
Runtime tests were not repeated for this wording-only change. The 286-test run, layout/ratchet checks and production negative control below are evidence from ab08a568, not new test-run claims for this head. Required CI and maintainer/security review remain pending before merge; this attestation does not claim completion of the new-head automated review.
Prior runtime validation at ab08a568f98bfc2a7df73dca26bb920b532f02c8, including dev081f64169f7e57624bed878d0494c3f7061d49a0:
bun scripts/test.ts --changed=origin/dev tests/config/local-credential-fence.test.ts tests/config/local-credential-generation.test.ts tests/cli/local-credentials.test.ts tests/cli/uninstall.test.ts tests/codex-integration/native-profile-healthz.test.ts tests/codex-integration/native-profile-manager.test.ts tests/codex-integration/native-profile-api.test.ts tests/codex-integration/native-profile-processes.test.ts tests/service/launchd-repair.test.ts tests/service/service-definition-escaping.test.ts tests/service/service-pinned-homes.test.ts --parallel=1 — 286 pass, 0 fail across the explicit eleven-file changed-mode selection. This is focused coverage, not the full import-connected suite.
The production-path case uses startServer, the real management switch route, NativeProfileManager and its default atomic writer. The refreshed upstream manager now delegates through writeNativeMainAuthFileAsync, which awaits that writer. An IPC observation wrapper delegates immediately; the independent parent probes production /healthz at 750 ms before releasing the peer-held SQLite fence. The test verifies unchanged source auth while excluded, then a successful switch and target auth after release. Fixture homes, keys, process/restart boundaries and blocked external fetch isolate operator state.
Repeated the caller negative control on this base: inserting blocking publication into the manager writer makes the same production HTTP health request expire at 750 ms. The original source was restored byte-for-byte before the passing focused run. The test/helper and the personal fence/launchd/orchestration fixes are unchanged from 9b36e298; the new upstream async helper remains on the tested caller path.
Credential-fence tests cover reader/writer contention, exclusion/reentrance, monotonic deadline checks before and after yielding, permanent errors and retry churn. Launchd cases cover accepted/refused bootstraps, unknown outcomes, preserved PATH and exact Interactive policy, pending definitions across repairs/token rotation, orphaned recovery files, concurrent cleanup and full uninstall with/without the plist. Other cleanup errors retain install state. Source guards isolate installation from restart; behavior cases cover the retry predicate.
bun run typecheck — no errors in 2,409 files. bun run privacy:scan, bun run structure:check and git diff --check origin/dev pass. bun test tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/ci-workflows/file-size-ratchet.test.ts — 38 pass, 0 fail. The layout conflict was resolved as the exact union of both effective mappings (3,048 entries), retaining the native-profile shard and the new upstream PR-gates membership.
cd docs-site && bun install --frozen-lockfile && bun run build — pass; 665 pages and 96,089 internal links checked. English and all seven lifecycle translations distinguish readable restoration attempts, unknown outcomes/inspection, checkable initial probes/GUI login, and best-effort creation of any original backup.
The preceding completed CodeRabbit review covers 9b36e298 and reported no actionable comments with 100% docstring coverage. This attestation does not claim completion of the refreshed head's automated review. Required CI and explicit maintainer security review remain separate requirements before merge.
Historical on-host evidence from the initial patch, not rerun measurements for this head: Interactive trials completed 2,254 health probes without expiration (maximum 275 ms), including 1,510 during six cold usage scans. The deadline stayed at 750 ms. This is not a guarantee under arbitrary system saturation.
Resource exception: earlier broad/import-connected attempts on the shared live Mac stopped after more than 3,600 and 1,156 passing tests respectively, with no reported assertion failure. Neither completed; neither is passing-suite evidence. The explicit selection covers these changes without repeating those disruptive runs. Full repository/import-connected and cross-platform completion remains for maintainer CI. No manual full-CI dispatch was launched.

Summary by CodeRabbit
New Features
macOS background services use the Interactive resource policy. Run ocx service repair after upgrading to apply it to existing installations.
Health checks remain responsive while a local credential update waits for a lock; the update proceeds once the lock is available.
Reliability
Repair retains the original backup until launchd accepts the changed definition and a check confirms the matching job. Pending changes are retried during later repairs.
If launchd rejects a change and its state is checkable, repair attempts to restore the previous definition. Install and uninstall clean up recovery files; cleanup failures are reported, while best-effort backup removal after verified repair does not change its result.
Documentation
Updated service lifecycle and credential-update guidance across supported languages.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds asynchronous retries for credential-publication lock acquisition and updates macOS launchd definitions to use ProcessType=Interactive. Repair tracks unconfirmed definitions and recovery files across attempts. Tests and documentation cover both changes.
Async acquisition retries SQLITE_BUSY with timer yields within a 10-second deadline. The callback runs only after lock acquisition. Tests cover contention, callback cleanup, deadline refusal, and malformed databases. Documentation describes retry timing and /healthz responsiveness while an update waits.
The integration test checks health responses and profile state while a profile switch waits on a held fence. It then checks the switch after release. The helper creates the isolated server and profile fixtures; layout files assign tests to their profiles.
The generated plist sets ProcessType=Interactive. PATH comparison ignores that policy line while retaining the installed normalized PATH. Tests cover migration and PATH preservation. Documentation describes the policy and repair behavior.
Repair writes a pending marker for changed definitions and requires an accepted bootstrap and matching probe before clearing it. Pending repairs retain the rollback definition and cannot use command-only no-op or kickstart paths. Uninstall removes recovery files and retains install state if cleanup fails. Tests and documentation cover retry, rollback, and cleanup outcomes.

Do not accept a command match after a failed bootstrap.
If bootout fails and the old job remains loaded, bootstrap can fail while probeLaunchdLoadState still returns loaded-current: the policy change does not change the command. installLaunchd then reports success and deletes the backup, although launchd still has the old policy. A later repair can be a no-op.
When the plist changed, require evidence that launchd loaded the new definition. Report failure and preserve a recoverable state otherwise. Add a regression test for failed bootout and bootstrap with the old command still loaded.

Preserve the installed PATH during a policy-only migration.
If an older plist has a login-shell PATH and a tray helper or cron job runs ocx service repair with a narrower PATH, the new ProcessType line makes reusePreviousPlistPathVariable return null (src/service/launchd.ts Lines 119-130). installLaunchd then writes the repair process’s PATH (src/service/launchd.ts Lines 652-663). The service keeps that narrower PATH after the policy upgrade, so commands that previously resolved through the installed PATH can stop working. Preserve the previous normalized PATH when ProcessType and PATH are the only differences, while still reloading the new policy. Add that combined case beside the migration test in tests/service/launchd-repair.test.ts Lines 176-192.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
The 750 ms probe timeout can make the test flaky on loaded CI machines.
AbortSignal.timeout(750) mirrors the production deadline. The test spawns two Bun child processes on a shared runner. The first /healthz request after the child starts a switch can exceed 750 ms because of scheduler noise alone. This would give a false regression signal.
Consider a more generous bound on the probe. Alternatively, measure latency against a baseline probe taken before the switch starts. The line 66 probe could supply that baseline. The test still catches a blocked event loop, because a native SQLite wait would block for up to 10 seconds.
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Cleanup can mask the original failure.
If finish(owner, ...) or finish(server, ...) throws, removeTreeWithRetry(root) does not run. The temporary directory then leaks. Also, an error thrown from finally replaces the test assertion failure. Wrap each cleanup step so that all steps run and the first assertion error survives.

…t its deadline
Review follow-ups on the launchd policy migration and the async credential fence:
- A refused bootstrap while the job still runs the expected command no longer
evicts it to reload the old definition; the previous plist is restored on
disk and the definition stays pending for the next repair.
- A backup that cannot be written removes an older run's .plist.prev, so a
pending rollback never restores another run's command or environment.
- The async fence tries once more after its final wait, as SQLite's busy
handler would, instead of failing while a peer has just released.
- Split the English lifecycle guidance into paragraphs.

…ng repair
Security review follow-up. When this run has no backup of its own (the
installed plist is unreadable, or writing .plist.prev failed), remove any
older .plist.prev before writing the pending marker, and fail before
touching the plist or launchd if it cannot be removed; otherwise a later
failed repair could restore an older command and proxy environment.
Guard the read-only-file test for root and Windows, and note that the
async fence gives up SQLite's PENDING-lock writer priority.

Value: A local proxy that keeps serving generations but misses its 750 ms /healthz deadline makes the CLI report it offline. This PR removes two causes on dev: the macOS launch agent ran in launchd's default daemon class, which throttles CPU and I/O under load, and withCredentialPublicationFenceAsync used SQLite's synchronous busy handler, which could block every HTTP request in the process for up to 10 s while a peer held the credential-publication fence. The plist now declares ProcessType=Interactive (install/repair migrates once, preserving the installed PATH), and the async fence makes non-waiting attempts with async backoff inside the same monotonic 10 s budget.
Maintainer changes (a7943be, 20a877f), from independent technical and security reviews: a refused bootstrap while the job still runs the expected command no longer evicts it during rollback (previous plist restored on disk, definition stays pending); a backup that cannot be written removes an older run's .plist.prev and, when this run has no backup of its own (failed write or unreadable installed plist), any older .plist.prev is removed before the pending marker, failing before any change if it cannot be, so a pending rollback never restores another run's command or proxy environment; the fence tries once more after its final wait. Each change has a regression test that fails on the previous head. Branch merged with dev.
UX change: after upgrading, the first ocx service repair (also run by ocx update) reloads the macOS agent once to apply the policy; later repairs are no-ops. If launchd refuses the changed definition, repair reports failure and the definition stays pending until a repair confirms it.
Existing users: credential values, generation formats and fence exclusion are unchanged; writers that wait now let health checks and other requests run. A repair whose launchd state cannot be read still refuses before writing anything.
Windows: the launchd changes are macOS-only. The fence change is shared: on Windows the same async retry replaces SQLite's blocking wait with the same budget and error handling.
Reviews at exact head 20a877f: fresh technical review PASS, fresh security review PASS (both claude-opus-5-5 after DeepSeek attempts returned 429). Remaining notes are low: the seven translations do not yet carry the new left-running sentence (nothing contradicts the code), and a strict pending-marker unlink failure after a confirmed load reports failure and reloads again on the next repair, as documented.

Summary
A local proxy could keep serving generations while its CLI reported it offline:
/healthzmissed the unchanged 750 ms probe deadline under contention. Fix two additional causes alongside the Keychain and usage-scanner work in #8337, #8450 and #8455.ProcessType=Interactive. The default launchd daemon resource class throttles CPU and I/O even though Codex and dashboard responsiveness depend on this local proxy. In the on-host diagnosis the daemon ran at priority 20; registering the interactive definition changed it to 31. Adaptive is unsuitable because the proxy does not use XPC transactions. Install/repair upgrades a legacy definition once; later repairs stay idempotent.withCredentialPublicationFenceAsyncno longer invokes SQLite's synchronous ten-second busy wait. It makes nonwaiting attempts and yields between SQLITE_BUSY retries within the existing monotonic ten-second budget. The callback still starts only after exclusive acquisition, nested holders remain reentrant, errors fail closed, and the original SQLite error is retained on expiration. The synchronous API retains its existing contract..prevbackup after a verified repair writes state remains best effort and does not change its success. Successful overlapping repair can still persist install state if its marker was already removed. Lifecycle guidance in English and all seven translations now distinguishes readable failure/restore attempts, unknown-state outcomes and inspection, checkable initial probes/GUI sessions, and best-effort backup creation.Security review required before merge: this changes credential-publication lock acquisition. In particular, review exclusion, reentrance, error classification and deadline behavior. No credential values, generation formats, attestation rules or incoming-auth policy are changed. Observer events are not coalesced and no coverage validation is skipped.
