fix(service): macOS repair no longer evicts a healthy launchd job, and verifies the one it loads

[lidge-jun]

Stack (hub single-port, #4236): 1 #4249 → 2 #4250 → 3 #4251 → 4 #4252 → 5 docs (next). Each PR targets the previous branch; retarget to dev as the one below lands. Local suite deliberately not run (operator instruction); hosted CI on the pushed head is the proof.

Summary

ocx service repair on macOS IS installLaunchd, and it was the only backend that evicted first and verified never. It booted the live job out of gui/$uid, re-registered with the domain-implicit legacy launchctl load -w, and accepted exit-0-with-empty-stderr as proof. On a hub that takes the public proxy, the management ingress and the unauthenticated loopback listener down in one command, with no error, no rollback, and nothing appended to the service log — because the job never started again. Recovery needed exactly one command the CLI never printed: launchctl bootstrap gui/$(id -u) ~/Library/LaunchAgents/com.opencodex.proxy.plist.

The second half is what sends an operator there on a false premise. diagnoseService() derived "loaded" from sh("launchctl list | grep <label> || true"): the caller's bootstrap domain rather than gui/$uid, every exit code swallowed twice (|| true plus a catch), the label matched unanchored anywhere on a line, and no "unknown" state at all. A serving gui-domain job queried from a non-Aqua session read as installed, not loaded with re-run 'ocx service repair' attached — the command that causes the outage. That one bit also fed enabled, running, viable and therefore isServiceViable(), which src/update/index.ts and src/update/job.ts use to decide whether to start a competing proxy on the service's own port.

installLaunchd now has a protocol instead of a sequence.

• It asks launchd what it is running before touching anything, through the tri-state probeLaunchdLoadState — never the two-state launchdJobMatchesPlist, which reports loaded: false for every non-zero launchctl print (EPERM from a non-Aqua ssh/cron context, an unspawnable launchctl, an undocumented status). That distinction is the whole point: with the two-state answer a healthy serving hub failed the pre-check (evict), failed the verification the same way (evict again, roll back) and was finally told "IS NOT RUNNING" while it was up. An unknown probe is not evidence, so it refuses: nothing is written, no verb is run, and the error says the job may be RUNNING and names launchctl print gui/$uid/<label> and launchctl print user/$uid/<label>.
• A loaded-current job, an unchanged data-token file and an identical plist mean there is nothing to repair: it re-asserts 0600, refreshes install state, logs service is already loaded from the current plist; nothing to do. and returns without a single launchctl call. A repair of a healthy service must not be an outage. "Identical" has to tolerate PATH: buildPlist bakes process.env.PATH, and repair runs from whatever has a shell — a tray helper, ocx update's child, ssh — so a whole-file comparison missed almost every time it mattered, and the healthy hub was evicted and had its PATH narrowed to the caller's. When PATH is the ONLY difference and the live job runs the exec line this install baked, the previous definition's PATH is put back (reusePreviousPlistPathVariable), the files then compare equal on their own terms, and the PATH the service already runs with survives. Anything else differing is a real rewrite, PATH included — that residual is deliberate, since PATH must stay updatable and the eviction was going to happen anyway.
• The previous bytes are kept in memory and at <plist>.prev before the overwrite. Not .prev.plist — launchd globs ~/Library/LaunchAgents/*.plist at login, so that spelling would be a second registration of the same Label fighting the real one for the port.
• The reload is bootstrap gui/$uid <plist>, the verb that pairs with the bootout target, after a bounded 5 × 200 ms settle while launchctl print still answers 0. bootout is asynchronous, which is why the old back-to-back retry raced the same exiting job twice and added nothing. A bootout that exited 3 is not settled — nothing is exiting to wait for.
• Every domain the probe can answer for is evicted, not just gui/. The probe asks gui/$uid and user/$uid; the mutating verbs asked gui/$uid alone. Against a user/-domain registration of our Label that made ocx service stop a silent no-op (exit 3 in a domain that never held it), made the install cleanup lay new assets over a live manager, and left installLaunchd bootstrapping a second registration into gui/ — two KeepAlive jobs fighting for one port. launchdEvictionTargets() is now the shared list for installLaunchd, stopLaunchd and the install-cleanup stop; bootout against a label a domain does not hold exits 3 and changes nothing, so both are addressed unconditionally rather than enumerated first.
• Success is the probe answering loaded-current, never a stderr regex, and writeServiceInstallState runs only after it does. <plist>.prev is deleted at that point instead of surviving until the next uninstall. It compares the command this install baked, not expectedLaunchdCommand(installedServiceListenPort()): a fresh install has no state yet, and a lost state file makes that helper fall back to the Bun + CLI pair, which would call a correctly loaded launcher job stale (mise upgrade leaves launchd proxy running an old OpenCodex version #3464) and turn every first install into a rollback.
• One retry, routed by the failure. Measured on this host (macOS 26 / Darwin 27.0.0, arm64) with a throwaway com.opencodex.test-probe label, Bootstrap failed: 5: Input/output error has two causes: something is still bootstrapped under the label, or the label sits in the domain's disabled list. The -w in load -w was silently doing the second job, so dropping it without enable would have made a disabled job permanently unrepairable. The retry tries kickstart -k (live job) then enable + bootstrap (disabled list) — and enable runs only there, so an ordinary repair does not quietly undo a deliberate launchctl disable. Exit 0 with a disagreeing probe is the silent no-op and earns one more eviction. Anything else (malformed plist, EPERM) throws immediately so the real stderr reaches the operator undelayed. An unknown probe is never retried: a retry is another eviction.
• kickstart -k is trusted only for bytes already on disk. launchd restarts the definition it has cached; it does not re-read the plist. When only EnvironmentVariables changed the exec line is unchanged, so the verification would agree, install state would be written and repair would report success while launchd kept the OLD environment. New bytes (a fresh install included) therefore skip kickstart and go to enable + evict/bootstrap, the only way to hand launchd a new definition.
• On terminal failure it restores the previous bytes, tries to bootstrap them back, and throws an error that says what the probe actually found — not-loaded: evicted and not running (or restored and re-bootstrapped); loaded-stale: still loaded, from a different command than the plist just written, because telling that operator "nothing is listening" sends them to fix the wrong thing. Both name launchctl bootstrap gui/$uid <plist> as the remedy and point at launchctl print and launchctl print-disabled. When the probe answers unknown after the attempts it neither evicts again nor rolls back (a rollback is another eviction): an accepted bootstrap warns and records state, a refused one throws with the real stderr and an explicit "this says nothing about whether it is running".
• stableLauncherEntry() prefers the launcher the install already recorded while it is still an absolute executable file. A repair run from a context without ocx on PATH — a tray helper, ocx update's child, ssh — used to rewrite a working launcher-form plist into the version-pinned Bun + CLI pair and then evict the healthy job to load it. This reaches Linux too: installSystemd resolves the same function, so a PATH-less repair now keeps the ExecStart the unit already has. The consequence there is milder — systemd reloads and restarts, it never evicts into nothing — but the silent rewrite was identical, so the behaviour is shared deliberately rather than branched, and tests/service/service.test.ts covers the systemd side directly.

ocx service restart now restarts, instead of inheriting the no-op. restart mapped to the repair path, so the fix above turned it into a lie on macOS: a restart of a healthy service reloaded nothing, and the operator documentation had to tell people to run launchctl kickstart -k gui/$(id -u)/com.opencodex.proxy by hand. installLaunchd now returns LaunchdInstallOutcome { reloaded } — false only on the no-op path, which is the only path where launchd was never asked for anything — and repairService takes the verb. On darwin, restart plus reloaded: false runs kickstart -k gui/<uid>/<label>: it restarts what the domain already holds, so there is no eviction window, and it cannot publish bytes, which is irrelevant when there are none to publish. Success is the same tri-state probe, against the exec line an install would bake; it logs one line (service restarted (launchctl kickstart -k gui/<uid>/com.opencodex.proxy).), warns on unknown because that is not evidence, and throws on absence or a refused kickstart — after which the repair branch still runs its reportServiceServing health wait, now reporting restarted. repair keeps the no-op: a repair of a healthy service must not be an outage, and only the verb that promises a new process costs one. normalizeServiceSubcommand therefore stops folding restart into repair (a bare ocx service still selects repair — it is an idempotent "make it current", not a request to bounce a healthy hub). Windows and Linux are unchanged and were checked rather than assumed: the scheduler repair already stops then starts the task, WinSW repair restarts the service, and installSystemd ends in an unconditional systemctl --user restart, so neither platform has a no-op to compensate for and neither reads the verb. One related message moved with it: src/cli/version-skew.ts advised ocx service repair for an old running proxy, which a byte-identical definition now makes a no-op, so it advises ocx service restart.

The "loaded" bit is now a four-state verdict. New probeLaunchdLoadState() asks launchctl print in both gui/<uid> and user/<uid> the way inspectLaunchd does, keeps the 112/113 distinction, and returns loaded-current / loaded-stale / not-loaded / unknown. deriveLaunchdServiceDiagnostic() is pure, so all four are testable without a live launchd.

unknown is the one that used to do damage, and it is handled in both directions. Its summary says the state could not be verified and names no repair command. And it keeps viable true, because isServiceViable() === false is precisely what makes the update fallback treat a successful repair as a dead supervisor and start a competing proxy; a probe that could not be run is not evidence against the service. startable is likewise untouched, so the tray still hands the start to ocx service start, which no-ops on an already-loaded job. src/cli/status.ts still appends "registered but NOT serving … re-run 'ocx service repair'" only when installed && !live, which stays honest: unknown above a live proxy prints the unverified summary under ✅ Proxy: running and recommends nothing. loaded-stale keeps the viability the grep era gave it, so the update path behaves exactly as before, and only gains a summary that finally says the live job came from an older plist — the one case where repair is right.

Around it: the install-cleanup twin uses the same probe and bootout in both domains (legacy unload cannot evict a gui-domain job, as the file's own comment says), treats 0/3/112/113 per domain as benign and throws on anything else, and still fails closed on unknown, because installing new assets over a manager nobody could query is the unsafe direction. stopLaunchd/uninstallLaunchd use bootout in both domains too, with unload kept only for status === null, i.e. launchctl could not be spawned at all. And serviceCommand's repair branch wraps repairService() so reportServiceServing("repaired") runs even on a throw — which matters more now that darwin repair can roll back, since the operator needs the "did anything come back?" answer. The exit code stays non-zero either way.

Two pre-existing test-safety holes, both of which were hitting the maintainer's own machine. os.homedir() reads the password database rather than $HOME, so the suite's HOME sandbox never moved ~/Library/LaunchAgents and the existing withLaunchAgentHome() helper was inert: every installLaunchd case rewrote the live com.opencodex.proxy.plist with a definition whose token file, log path and homes pointed into a temp directory. launchd keeps its own parsed copy, so nothing broke until the job next restarted. assertNotRealLaunchAgentsUnderTest plus an injectable plistPath make that refusal mechanical. Separately, serviceStatePaths() now drops its legacy default-home entry under an armed test process — that entry is the real ~/.opencodex/service-state.json, and a sandboxed run was observed replacing the live record's codexHome and opencodexHome with /var/folders/... paths. That filter asks the guard's own isProtectedHomeUnderTest(), so one canonicalization decides it (a local resolve() calls /var/folders/... and /private/var/folders/... different directories on macOS), and writeServiceInstallState goes through serviceStateWritePaths(), which throws when the filter leaves nothing: with OPENCODEX_HOME unset under an armed guard both candidates resolve to the real home, the list went empty, and the writer silently wrote nowhere while reporting success. Reads stay quiet, because an empty read list really does mean "no install state".

Issue defects 3 and 4 (an occupied secondary listener port misdiagnosed as a public-port conflict; ocx status comparing client fences against the public port only) are left to the next PR in this stack, which owns the loopback listener. startLaunchd deliberately keeps load -w: switching it would change ocx service start semantics, since -w clears the disabled list and bootstrap does not, and it already cross-checks with launchdJobMatchesPlist before throwing.

This PR targets dev and is the base of a four-PR hub single-port stack.

Verification

• tests/service/launchd-repair.test.ts, 54 cases, registered in both scripts/test-layout/layout.json and tests/fixtures/test-layout-expected.json. Every case injects plistPath into its own fixture directory and a scripted tri-state probe, so none of them can reach the real LaunchAgents path or a live launchctl — and one case asserts the guard refuses that path. OPENCODEX_HOME is pinned per case and restored in afterEach, so this file no longer leaks its temp home into the next file in the same Bun worker.
• Coverage: the healthy-and-identical repair makes zero launchctl calls; a plist differing only in the baked PATH is also a no-op and keeps the installed PATH on disk; an identical plist whose live job runs an older command still reloads and deletes <plist>.prev; the reload is domain-explicit bootstrap preceded by a bootout of both domains with no load/unload anywhere; the settle loop waits while print answers 0, stops at 5 × 200 ms per evicted domain, and is skipped for a bootout that exited 3; exit 0 with a disagreeing probe is a failure whatever stderr says; exit 5 tries kickstart -k for unchanged bytes and refuses to trust it for an env-only change (two bootstraps, no kickstart); a disabled job takes enable + bootstrap in a pinned twelve-verb sequence while an ordinary repair never runs enable; a malformed plist is not retried; terminal failure restores the previous bytes and names the manual remedy and print-disabled; a loaded-stale outcome is reported as loaded rather than down; a fresh install invents no rollback; an unknown pre-check changes nothing at all — no verb, no file, no .prev — and names both print commands; an unknown after an accepted bootstrap neither retries nor rolls back; an unknown after a refused one throws without "IS NOT RUNNING". Plus reusePreviousPlistPathVariable (PATH-only, anything-else, identical, a PATH containing $&, a definition with no PATH entry), launchdEvictionTargets, the probe tri-state from 0/112/113 and a spawn failure including "113 in gui/ is not absence, ask user/ too", and all four diagnostic states with unknown producing neither "installed, not loaded" nor a repair recommendation and not disproving viable. Source-oracle cases cover what cannot be driven without a live launchd or a whole CLI process: the repair branch's try/catch ordering, the install-cleanup ops (both domains, benign statuses), installLaunchd never reaching for launchdJobMatchesPlist while startLaunchd deliberately still does, the PATH pre-check, the state-path filter plus its fail-loud write path, stop/uninstall, and the launcher resolver shared with installSystemd.
• The five obsolete installLaunchd cases in tests/service/service.test.ts asserted the load verb and the stderr success condition, so they are replaced rather than extended; what they proved about bounded retries and about not retrying an unrelated failure is preserved in the new file. stableLauncherEntry's two discovery cases now pass state: null, one new case covers the recorded-launcher preference (and the refusal of a relative value), and another covers the systemd half of it.
• The restart verb adds 8 cases to that file: restart of a healthy loaded-current job runs exactly kickstart -k on the gui domain and no bootout/bootstrap; repair of the same state runs zero launchctl calls and never reaches the restarter; restart of a not-loaded job takes the ordinary evict/bootstrap path with no kickstart; installLaunchd returns { reloaded: false } / { reloaded: true } for the two paths; restartLaunchdJob prints the one line naming the command it ran, throws when the job is gone afterwards, and only warns on unknown; and a source-oracle case pins the darwin wiring (restart verb only, defaulting to the real restarter) together with the unconditional systemctl --user restart that makes Linux need no equivalent. Every one of them injects the restart seam — the default would kickstart the maintainer's live hub, and kickstart is not on the live-service-manager guard's read-only list, so even a default call from an armed test process fails closed. tests/service/service.test.ts covers the verb surviving normalizeServiceSubcommand, planServiceCommand and selectServiceSubcommand, plus the shared dispatch branch.
• Commands run, from a worktree with node_modules symlinked:
  • bun run typecheck → clean.
  • bun test tests/service/launchd-repair.test.ts → 54 pass, 0 fail, 195 expect().
  • bun test tests/service/service.test.ts → 205 pass, 0 fail, 674 expect().
  • bun test tests/cli/cli-version-skew.test.ts → 29 pass, 0 fail; bun test tests/cli/cli-help.test.ts → 17 pass, 0 fail (both touched by the verb's wording).
  • bun test tests/service/launchd-repair.test.ts tests/service/service.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts → 268 pass, 0 fail, 1388 expect().
  • bun test tests/service tests/update tests/cli/uninstall.test.ts → 765 pass, 9 fail.
  • bun run privacy:scan → passed.
• Those 9 failures are pre-existing: 8 winsw cases plus xAI API-key runtime injects priority while OAuth does not. They are cross-file OPENCODEX_HOME pollution inside one domain-wide bun test invocation — bun test tests/service/winsw.test.ts alone → 25 pass — and the same 9 failed on dev before this branch existed. Not touched here.
• The full suite was not run, by operator instruction (focused files plus typecheck only). Hosted CI on the pushed head is the proof.
• The launchctl exit codes this change depends on were measured on the affected host rather than assumed, with a throwaway com.opencodex.test-probe label in a temp plist. The live com.opencodex.proxy job was never booted out, bootstrapped, kickstarted or enabled — in either round: launchctl print gui/501/com.opencodex.proxy returned 0 before and after every probe, and the probe was booted out and its files deleted. launchctl enable/disable write a per-uid override database with no removal verb, so print-disabled retains an inert "com.opencodex.test-probe" => enabled record for a label that no longer exists. The full table is in the devlog.
• The two real files the pre-existing test holes damage were verified and restored again at the end of this round: plist 1985 bytes, 0600, plutil -lint OK, command and EnvironmentVariables byte-identical to the running job's own launchctl print; service-state.json 320 bytes with the real homes; service-api-token untouched; /healthz on 10100 → 200; no *.prev left behind. The damage happened twice during this round and neither time from this branch's tests: every installLaunchd write here is refused by assertNotRealLaunchAgentsUnderTest, and the only other writer of that path (uninstallLaunchd) is guarded identically. Concurrent sessions in other worktrees ran the unguarded suite and wrote /var/folders/.../opencodex-test-* homes into both files; the clobbered state record names its writer in cliPath (once .claude/worktrees/agent-ae68eb45f20e1f3c6, once a sibling agent's scratchpad worktree). launchd keeps its cached copy, so nothing broke until the next restart would have — which is both the case for landing these guards and the reminder that a guard only protects the branch carrying it. Worth re-checking the two live files once any concurrent session finishes.

📝 Walkthrough

Walkthrough

The change updates macOS launchd installation, probing, cleanup, diagnostics, repair reporting, restart handling, launcher reuse, and test isolation. It adds rollback, domain-aware commands, tri-state verification, and focused launchd repair coverage.

Changes

Launchd service repair

Layer / File(s)	Summary
Path safety and command resolution src/lib/test-home-guard.ts, src/service.ts, tests/service/service.test.ts, tests/service/launchd-repair.test.ts	The test guard protects the real ~/Library/LaunchAgents directory. Service-state writes fail when no safe path remains. Recorded absolute launchers take precedence over PATH. Shared command generation keeps plist rendering and verification aligned.
Launchd installation and rollback src/service.ts, tests/service/launchd-repair.test.ts	installLaunchd() probes before changing files, skips current jobs, preserves prior plist bytes, uses domain-explicit bootout and bootstrap, bounds settling, retries defined failures, refuses unknown state, verifies the loaded command, and restores previous bytes after terminal failure.
Load-state probing and cleanup src/service.ts, tests/service/launchd-repair.test.ts	Launchd probing checks GUI and user domains and returns loaded-current, loaded-stale, not-loaded, or unknown. Diagnostics distinguish stale and unverifiable jobs. Stop, uninstall, and cleanup prefer bootout and use legacy unload only when launchctl cannot be spawned.
Repair, restart, and validation src/service.ts, src/cli/registry.ts, src/cli/version-skew.ts, tests/service/*, tests/cli/cli-version-skew.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json, devlog/_plan/260911_hub_single_port/010_launchd_repair.md	repair leaves a healthy macOS job unchanged, while restart uses verified kickstart -k when no reload occurred. Repair errors still trigger serving checks and preserve a nonzero exit status. Help text, version-skew guidance, tests, fixtures, and the plan reflect the split behavior.

리뷰 · 우선순위 74 / 80

이 PR은 지금 dev(HEAD babb76449, #4240 L4 client-catalog 직후) 위에서 macOS 허브가 ocx service repair 한 번에 통째로 꺼지는 문제를 고칩니다. 이슈 #4236의 결함 1·2만 다룹니다. 허브 단일 포트 스택의 맨 아래 칸입니다. 위에 #4250 → #4251 → #4252가 이 브랜치를 베이스로 쌓여 있고, 결함 3·4(부포트 오진·ocx status fence)는 다음 PR 몫으로 남겨 둔 상태입니다.

지금 dev의 src/service.ts 안 installLaunchd는 먼저 bootout으로 살아 있는 잡을 쫓아내고, 도메인을 명시하지 않는 옛 launchctl load -w로 다시 올리고, stderr가 비면 성공으로 칩니다. 검증이 없습니다. 그래서 공개 프록시·관리 ingress·루프백 리스너가 한 명령에 같이 내려가고, 롤백도 없고, CLI가 복구 명령도 안 알려 줍니다. 같은 파일의 diagnoseService darwin 쪽은 launchctl list | grep에 || true를 붙여 “로드됨” 한 비트만 뽑습니다. 호출자 세션 도메인만 보고, 실패도 전부 “안 올라감”으로 뭉갭니다. 그 비트가 enabled/running/viable로 흘러 isServiceViable()까지 가고, src/update/index.ts와 src/update/job.ts는 그걸 보고 서비스 포트에 경쟁 프록시를 띄울지 결정합니다. 건강한 허브를 “죽었다”고 오진하면 repair 추천 → 실제 장애, 혹은 업데이트 경로의 이중 프록시로 이어집니다.

이 PR이 넣는 프로토콜은 대략 이렇게 읽힙니다. 새 probeLaunchdLoadState가 gui/$uid와 user/$uid 둘 다에 launchctl print를 묻고 loaded-current / loaded-stale / not-loaded / unknown 네 값을 돌려줍니다. installLaunchd는 파일을 쓰기 전에 이 프로브를 보고, unknown이면 손대지 않고 거부합니다. 이미 loaded-current이고 plist·토큰이 같으면 launchctl을 한 번도 안 부르고 “nothing to do”로 끝냅니다. PATH만 다른 경우는 reusePreviousPlistPathVariable로 설치본 PATH를 되살려 통째 비교가 맞게 합니다. 진짜로 고쳐야 할 때만 <plist>.prev 백업 뒤 양쪽 도메인 bootout → settle → bootstrap gui/$uid, 성공은 프로브가 loaded-current일 때만, 실패 시 롤백과 “지금은 내려간 건지 / 다른 커맨드로 올라와 있는지”를 구분한 에러를 냅니다. kickstart -k는 디스크에 이미 있는 바이트에만 믿고, 새 바이트면 enable+재퇴거로 갑니다. deriveLaunchdServiceDiagnostic은 순수 함수라 unknown일 때 viable을 참으로 남겨 업데이트 폴백이 경쟁 프록시를 안 띄우게 합니다. stableLauncherEntry가 기록된 런처를 우선해서, PATH 없는 tray/ocx update 자식에서도 런처형 plist를 Bun+CLI 쌍으로 바꾸지 않습니다. 이 함수는 installSystemd도 쓰므로 Linux 쪽 silent rewrite도 같이 막습니다. 테스트가 산 개발자 LaunchAgent·service-state.json을 덮어쓰던 구멍은 assertNotRealLaunchAgentsUnderTest와 serviceStateWritePaths로 막았습니다. tests/service/launchd-repair.test.ts가 프로토콜·PATH 재사용·양쪽 도메인·unknown 거부를 직접 커버합니다.

라인 1193 - probeLaunchdLoadState가 printedText.includes(expected)로 current/stale을 가릅니다. 기대 커맨드 문자열이 print 출력 어딘가에만 있으면 current로 칩니다. 지금은 커맨드가 길고 특이해서 실무 위험은 낮지만, 부분 문자열이라 이론상 오탐 여지가 있습니다.
라인 1213-1214 - settle이 최대 5×200ms(약 1초)입니다. 부하 큰 Mac에서 bootout이 더 늦으면 Bootstrap failed: 5 재시도 경로로 넘어갑니다. 재시도가 있어서 치명적이진 않지만, CI/실기에서 settle 부족 신호가 나오면 횟수만 늘리는 게 안전합니다.
라인 2668-2750 - 퇴거는 gui+user 둘 다인데 재등록은 항상 bootstrap gui/$uid만 합니다. headless( gui 도메인 112 )에서는 의도적으로 not-loaded/실패로 떨어지게 설계했지만, user 도메인만 쓰는 특수 환경은 이 PR 범위 밖입니다.
startLaunchd / launchdJobMatchesPlist - start 경로는 의도적으로 옛 2상태 헬퍼를 유지합니다. repair/status만 4상태로 바꿨습니다. 문서와 소스 오라클에 명시돼 있어 버그는 아니지만, 나중에 start도 같은 프로브로 맞출지 한 번은 결정이 필요합니다.
로컬 스위트 - PR 본문에 “로컬 스위트 고의로 안 돌림, hosted CI가 증거”라고 적혀 있습니다. 지금 메인 test/macos shard는 아직 pending이고, 전용 macos-launchd 잡은 통과로 보입니다. merge 전에 전체 shard 녹색을 확인하는 게 맞습니다.

메인테이너의 판단이 필요한 지점

• 이 PR을 macOS: ocx service repair unconditionally evicts the running LaunchAgent, accepts a no-op launchctl load as success, and leaves the hub down with no log line #4236 스택의 베이스로 먼저 dev에 넣을지, CI 전부 녹색 후에만 넣을지
• startLaunchd를 이번 트레인에서 4상태 프로브로 올릴지, 아니면 “start는 그대로 / repair·status만”으로 이번 범위를 고정할지
• settle 1초 상한을 실기 허브에서 충분한지, 아니면 보수적으로 늘릴지
• headless/ssh-only Mac에서 repair가 “거부하고 안내만” 하는 현재 동작이 운영 정책과 맞는지

너의 추천
CI 메인 test·macos shard가 녹색이면 #4249를 스택 1번으로 먼저 merge하세요. #4236 결함 1·2의 실제 장애를 끊는 베이스이고, 위에 얹힌 #4250/#4251/#4252는 이 브랜치를 기다리므로 여기가 막히면 전체가 멈춥니다. merge 후 이슈 #4236은 결함 3·4가 남을 테니 바로 close하지 말고, PR2 쪽으로 범위를 남기세요. 로컬 풀스위트는 운영자 지시대로 스킵해도 되나, merge 직전 hosted CI 전체와 macos-launchd 재확인은 필수입니다.

Pass one resolved runtime and port to both launchd operations.

buildPlist resolves the runtime at src/service.ts:531 and the port through launchdServiceCommand at src/service.ts:538. installLaunchd then calls launchdServiceCommand(launcher) again at src/service.ts:2563, which independently resolves both values.

If either input changes between resolutions, the plist and expectedCommand contain different values. loadTook() then reports matchesPlist: false and the install can roll back a valid service. durableBunRuntime() recomputes its result on every call, and resolveServiceListenPort() rereads environment and configuration on every call.

Resolve both values once in installLaunchd. Add port to buildPlist dependencies and pass both values through to launchdServiceCommand, matching the existing single-resolution safeguard for durable runtime paths.

 export function buildPlist(
   proxyEnv: { name: string; value: string }[] = resolvedProxyEnv(),
-  deps: { launcher?: string | null; runtime?: DurableBunRuntime } = {},

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Resolve runtime and port once in installLaunchd.

At src/service.ts:2666, launchdServiceCommand(launcher) resolves durableBunRuntime() and resolveServiceListenPort(). At src/service.ts:2687, buildPlist resolves the runtime again, and its nested launchdServiceCommand resolves the port again. resolveServiceListenPort() rereads OCX_BAKE_PORT and loadConfig().port, so a concurrent configuration change can produce different command strings. The newly bootstrapped job can then be reported as loaded-stale; installLaunchd can evict it and restore the previous plist.

When launcher is set, the runtime does not affect the launcher command, but the port still does. When launcher is absent, both the runtime and port are part of the command. Pass the same resolved values to both paths.

♻️ Proposed fix

 export function buildPlist(
   proxyEnv: { name: string; value: string }[] = resolvedProxyEnv(),
-  deps: { launcher?: string | null; runtime?: DurableBunRuntime } = {},

Make this fixture change only EnvironmentVariables.

buildPlist emits ProgramArguments before EnvironmentVariables, and its launcher command embeds serviceApiTokenFilePath() under OPENCODEX_HOME. Therefore, replace(sandboxHome, ...) changes the first occurrence in the exec command. The production branch already skips kickstart when renderedDiffers is true, so this is a missing regression test rather than a current production failure. Replace the exact environment entry and assert that the exec line remains unchanged.

Broken Authentication

Reachability: Internal
Exploitability: Difficult
CWE: CWE-287 — Improper Authentication

Restore the token file during launchd rollback.

When OPENCODEX_API_AUTH_TOKEN changes, installLaunchd() overwrites the token file at src/service.ts:2721-2726 before launchd mutation. If bootstrap fails, the rollback at src/service.ts:2841-2846 restores only the plist. The restarted service then reads the new token, while existing clients still send the previous token through x-opencodex-api-key or Authorization.

Capture the token file’s existence and contents before writing. During rollback, restore readable previous contents with mode 0600, or remove the new file when it did not exist. Do not use readTextOrNull alone to infer absence because it also returns null for read errors. Add a regression test for token rotation followed by failed bootstrap.

2764-2764: 🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Abort the reload on a non-benign bootout and roll back persisted state.

launchctlBootoutBenign defines only statuses 0, 3, 112, and 113 as benign. installLaunchd currently ignores other statuses at src/service.ts:2764, so an EPERM from user/<uid>/<label> can be followed by bootstrap gui/<uid>. probeLaunchdLoadState checks the GUI domain first and can then report loaded-current while the user-domain job survives. Both KeepAlive jobs can compete for the same port.

Reject non-benign statuses before bootstrap, but route the rejection through rollback. A direct throw from evictEveryDomain is unsafe because installLaunchd has already written the new plist and token. If GUI bootout succeeded first, it also leaves the GUI job evicted. Restore the previous plist and token, or remove newly written state for a fresh install, before propagating the error.

Preserve the loaded launchd domain for restart

When probeLaunchdLoadState returns loaded-current for user/$uid, installLaunchd returns reloaded: false. repairService then calls restartLaunchdJob, which always runs kickstart against gui/$uid at src/service.ts:2908. The user-domain job remains unchanged, so the public restart contract is not met. The existing comments explicitly support both domains; they do not exclude user-domain jobs.

Return the probed domain in LaunchdInstallOutcome, pass it to restartLaunchdJob, and use it for the kickstart target and diagnostics. Add a regression test for an unchanged user/$uid job.
