fix(runtime): helper-lifecycle follow-ups (#666, #667, #668) and a detached-reap regression - #669
Conversation
The idle reaper's owner check was a bare kill(pid, 0), which answers "does a process hold this integer", never "is this still my launcher". A recycled PID at one tick pushes the deadline forward 12 hours, and the deadline only ever moves forward, so one false positive is never corrected — helpers were observed 33 hours past their timeout, 183 concurrent, 5.6 GB RSS. Owner liveness is now PID plus the launcher's kernel start time (read under LC_ALL=C so locale cannot disable the check), re-verified at most once a minute; a failed re-read keeps the previous verdict instead of declaring a live owner dead, and where no start time is known the check degrades to bare liveness. An absolute lifetime ceiling (24h default, CODEX_MULTI_AUTH_APP_ROTATION_MAX_LIFETIME_MS) bounds the leak if activity accounting is ever wrong again. Status telemetry is per helper PID instead of N writers last-writer- winning one file at 1 Hz, published on change plus heartbeat; readers prefer the newest live helper and still read the legacy path, and app-bind unbind walks every per-PID candidate through the same ownership-verified stop it applied to the shared file. Helpers remove their owner file on exit; launchers sweep metadata whose helper PID is dead — or provably recycled, by comparing the PID's kernel start time against the file's own timestamps — before spawning.

Shared per-PID status discovery moves next to its filename constant (listRuntimeHelperStatusPaths) and all three readers use it; rotation status derives selection and live count from one scan; only "running" counts as running so max-lifetime/error stamps read as terminal. The helper's identity probe is async and single-flight so a wedged ps stalls a background probe, never the proxy event loop. Metadata deletions retry transient Windows locks; the launch-path sweep memoizes identity probes per PID and caps them per sweep. app-bind unbind logs when it cannot enumerate per-PID files and retries the readdir. Tests: multi-helper and ownership-preservation unbind cases, publish-rate regression, sweep retry regression, max-lifetime status case, POSIX gate plus a Windows companion for the identity-unavailable degradation.

The detach grace hands a helper off optimistically: any launcher that exits cleanly within the window leaves its helper running. Nothing then checks whether a consumer actually took the handoff, so every short forwarded command strands a helper that holds the full idle timeout — 12h by default — with a dead owner, no traffic, and nothing connected. Owner death only stopped refreshing the idle clock; it never shortened it. Observed locally at ~3 stranded helpers per 15 minutes, ~1.1GB resident across 23 of them. Once the owner is confirmed dead the deadline becomes CODEX_MULTI_AUTH_APP_ROTATION_DETACHED_IDLE_MS (default 15m, 0 restores the previous behavior), and it fires only while the proxy reports zero open client connections — so a consumer that really did take the handoff, such as `codex app` giving the desktop app its proxy, is never reaped out from under. The proxy already tracked its socket set for shutdown; it now reports the count. A revived owner verdict clears the detached clock rather than ratcheting it, and the published idleExpiresAt reports whichever deadline is actually enforced.

A proxy shape whose getOpenConnectionCount() returns a non-finite value compared unequal to 0 and blocked the detached reap forever — failing in the one direction this fix cannot afford, and silently restoring the leak for that shape. Unknown now degrades exactly like a missing method does. Also proves the other half of the contract with a test: a detached consumer that reconnects per request, holding no socket between them, keeps its helper alive on the traffic alone and loses it once the traffic stops. The fixture proxy grows a ramped request counter, because a static counter cannot express "traffic is still arriving".

…n Windows CodeRabbit round 1. The comment on `countOpenConnections` described the fallback backwards: a proxy that cannot report connections reads as zero, and zero is the value that *satisfies* the owner-gone condition, so the missing-method case fails open into reaping rather than being "carried by activity alone". The behavior was the intended one; only the comment was wrong, and it documented a fail-open decision as fail-closed. Now it says which direction it fails in and why that direction is the safe one. The detached-window tests simulated owner death with an unmatchable start time, which only POSIX can evaluate, so the reap had no Windows coverage. A genuinely dead owner PID is readable through the degraded bare-liveness check on every platform: the new test owns a child, kills it, waits for the kernel to agree, and hands that PID to a helper. It runs on win32. `spawnDirectAppHelper` leaked a helper per readiness failure: the rejection throws before the caller reaches its try/finally, so nothing called `stopDirectAppHelper`. A leak-fix harness that leaks helpers is its own bug report. It now kills the child on the way out. Docs: both new lifetime overrides added to the settings reference, the per-helper owner file added to the AGENTS.md and privacy.md inventories, `CODEX_MULTI_AUTH_APP_ROTATION_OWNER_START_TIME_MS` added to the internal env list, and the ~500-word self-reaping paragraph split into a rule table.

…umer CodeRabbit round 2, and correct: Number.isFinite admits negatives, so a proxy answering -1 compared unequal to 0 and pinned a stranded helper alive forever — the same failure the previous commit claimed to close, one value short. Only a positive safe integer now counts as attached; negative, fractional, NaN, and Infinity all read as "nothing attached" and let the detached window run. Regression cases for -1, NaN, and Infinity, which needed the fixture proxy to be able to express a garbage reading at all.

Helper-lifecycle fixtures stood in for "dead" with integers above the platform PID ceiling (99999999, 2_147_483_646) and for "a second live process" with process.ppid. Neither is a fact the test controls. process.kill may raise EINVAL rather than ESRCH for an out-of-range PID; those fixtures classify as dead only because every liveness check in this tree treats every errno but EPERM as dead — true today, but a property they never state. process.ppid inside a vitest worker is the pool process, whose identity differs between the threads and forks pools and which can exit mid-run, flipping "(+1 more running)" to "(+0 more running)" with no code change. Spawning a child and killing it makes "dead" a fact; holding one open for the length of a test makes "live" a fact.

The detached reap added in #665 could kill a live `codex app` session. `codex app` relies on the detach grace rather than an explicit `detachOnExit`, so its launcher exits inside the grace window and the helper's owner is dead from the first tick. From then on the only thing standing between the desktop app and a dead proxy was `countOpenConnections() === 0` — and the proxy never sets `server.keepAliveTimeout`, so Node closes idle client sockets after its 5s default. A user who stops typing for the length of the detached window has zero sockets and no new requests, so the helper exits `owner-gone`, and the next message gets ECONNREFUSED against a dead localhost port with nothing left to restart it. Pre-#665 that session survived for the full 12h idle timeout. Gate the reap on the helper having *never* served a request. Every leaked helper in the #663 report had `totalRequests: 0`, so the leak is entirely a never-served phenomenon and the narrower gate closes it in full; a helper that served anything was genuinely handed off and falls back to the idle timeout and the 24h lifetime ceiling, which is where it sat before the detached window existed. Two more lifecycle fixes in the same tick: - The owner verdict is now three-valued. "No owner PID was recorded" and "the owner is confirmed dead" are different facts, and collapsing them into one `false` started the detached clock on the first tick for any helper launched without an owner PID — invoked directly, which is the documented reproduction in #663, or spawned by a pre-upgrade launcher — and reaped it silently 15 minutes later. `unknown` fires neither branch, which is what the pre-#664 `ownerPid && isAlive(ownerPid)` guard did. - The status heartbeat now accounts for the detached window. `publishToken` zeroes `idleExpiresAt`, so the published deadline only catches up on a heartbeat; pinned to the idle window alone, `rotation status` kept advertising a 12h deadline for a helper seconds from exiting, and under a short DETACHED_IDLE_MS override it never caught up at all. Also in this commit, both from the same review pass: - The metadata sweep runs after the helper spawn instead of before it. It is synchronous and unbounded — readdir, a readFileSync per live candidate, rmSync with a blocking backoff, bounded `ps` probes — and the state it cleans up is exactly the state that makes it slow, so it sat in front of `codex app` and TUI startup. Nothing about spawning depends on it. The launch timeout is armed after it either way. - Sweep deletions are guarded by an mtime re-check. Classifying a file as stale and deleting it are two moments, and a PID freed between them can be handed to a helper starting right now, which republishes that exact path before the delete lands. - The published wrapper's fault injectors need an explicit CODEX_MULTI_AUTH_TEST_FAULT_INJECTION=1 opt-in and a strict digits-only parse. `Number.parseInt` reads "2abc" as 2 and "1e3" as 1, so a value that was never meant to be a count could arm an injector in a user's install and silently defeat the first N metadata deletions of every sweep (#668).

Two branches removed a helper status file without checking `helperOwnershipMatches` but gated `removeHelperOwner` on it. When the status token and the owner token disagreed, unbind deleted the status file and kept `runtime-rotation-app-helper-owner.<pid>.json` — and because unbind then enumerated status paths only, nothing ever rediscovered that owner file. The launcher-side sweep is the only other thing that reclaims them, and it runs only when a new helper is launched, so a user who hit the leak and stopped using `codex app` kept those files forever. #666 asks for a deliberate choice between the conservative and decisive policies. This takes the decisive one: when the record's PID is proven dead, both files describe a process that no longer exists, so keeping the owner file preserves nothing. That is also what the launcher-side sweep already does with a dead PID, so the two paths now agree. The ownership gate still stands where it matters — a *live* PID whose ownership cannot be verified is preserved with a warning, untouched. Unbind now also enumerates owner files, so an owner file whose status record is already gone is reclaimed rather than being unreachable. A live PID's owner file is left alone. Helper stops run in a bounded pool instead of one after another. Each pays a SIGTERM, a graceful wait and possibly a SIGKILL, and on the machine from #663 there were 183 of them, so unbind blocked for minutes. Not changed, because the issue is wrong on this point: §2 reports that helper unlinks are not retried on Windows. `unlinkIfExists` (lib/runtime/app-bind.ts) already wraps `unlink` in `withFileOperationRetry`, so the `helperCleanupPaths` loop does get retries.

…ers (#667) "Which helper is current" was implemented twice, in lib/codex-manager/commands/rotation.ts and lib/runtime/runtime-current-account.ts, each hand-rolling its own `byRecency` sort and its own `state === "running" && isProcessAlive(pid)` filter. A single `rotation status` run executes both, so any drift between them produces a status line and an account marker naming different helpers. `printRotationStatus` made that concrete by calling `selectAppRuntimeHelperStatus` twice, either side of an awaited `printCodexAppBindStatus`: the liveness probes re-ran at a later instant, so a helper that exited during that await was named on the line while a different one fed the `current` marker two lines down. Both now use `selectRuntimeHelperStatus` from the new lib/runtime/app-helper-selection.ts, and `rotation status` selects once and threads one `now` through the line, the live count and the marker. Neither copy checked process identity, which was the substantive half of #667: `kill(pid, 0)` answers "does *a* process hold this integer", so a stale legacy `runtime-rotation-app-helper.json` left by a SIGKILLed pre-upgrade helper passes liveness the moment its PID is recycled, and marks an account `current` that no helper is using. The status files now parse `startedAt`, and liveness additionally requires the record to be fresh: a running helper republishes at least once per heartbeat (capped at 60s), so ten heartbeats of silence means the current holder of that PID did not write this file. Freshness rather than a kernel start-time probe because both call sites are synchronous read-only status paths reached from the interactive menu as well as the CLI — `readAppRuntimeHelperAccountSignal` is passed through `codex-manager.ts` as a sync function — and an identity probe costs a `ps` per candidate. The wrapper, which can afford it, still probes start times. PIDs are also validated as positive integers. Both readers accepted any finite number, so a corrupt or hand-edited record carrying `-1234` reached `process.kill(-1234, 0)`, a POSIX process-group probe that succeeds on any busy machine and reports a helper that does not exist as live. app-bind's own reader already required `Number.isInteger(pid) && pid > 0`; these two now agree with it. Test hygiene from #668 alongside it: the dead-PID and second-live-PID fixtures use processes the tests own rather than PID sentinels and `process.ppid`, `readAppRuntimeHelperStatus`'s recency sort is now exercised with two live candidates instead of one, and the hand-built owner-path literal uses `resolveRuntimeHelperOwnerPath`.

#664 moved helper status files to `runtime-rotation-app-helper.<pid>.json` and updated `docs/reference/storage-paths.md`, but the storage table in the README kept the pre-per-PID shared name.

`isRuntimeHelperProcessAlive` validated the PID and then asserted the result back with `as number`. Binding the validated value keeps the narrowing the validator already produced, so the one place that calls `process.kill` has no cast in it.

In `@docs/development/ARCHITECTURE.md`:
- Line 211: Update the Telemetry row in ARCHITECTURE.md to state that each
launcher spawns the next helper first, then sweeps metadata files whose helper
PID is dead. Preserve the existing descriptions of terminal status retention and
cleanup behavior.
In `@docs/reference/storage-paths.md`:
- Line 162: Update the runtime helper-state documentation near the owner-file
description to document that unbind independently enumerates owner files and
removes orphaned files whose PIDs are proven dead, in addition to the existing
launch-time sweep; mention codex-multi-auth rotation unbind-app as the operator
recovery path.
In `@lib/runtime/app-bind.ts`:
- Around line 1657-1682: Add a warning log in the orphan-owner loop when
isProcessAlive(owner.pid) causes the owner file to be preserved, including the
recorded PID and matching the warning style used by the surrounding helper
cleanup logic. Keep the existing skip behavior unchanged.
- Around line 1270-1306: Update mapWithConcurrency so only index >= items.length
terminates a runner; when an in-range item is undefined or comes from a sparse
slot, skip it and continue claiming subsequent indices instead of returning
early.
In `@lib/runtime/app-helper-selection.ts`:
- Around line 18-40: Add a test assertion linking RUNTIME_HELPER_STATUS_STALE_MS
to the wrapper’s configured heartbeat, ensuring the staleness window is at least
ten heartbeat intervals. Document or reference the heartbeat source used by the
assertion so future increases fail tests instead of silently invalidating helper
liveness detection.
- Around line 49-90: Add direct regression tests covering readRuntimeHelperPid
and isLiveRuntimeHelper for invalid PIDs, stale records, updatedAt set to null,
and future startedAt values, plus selectRuntimeHelperStatus recency ordering
among live helpers. Use process.pid or another owned live PID, avoid asserting
foreign-process errno behavior, and pass one fixed now value consistently to
selection and liveRuntimeHelpers count assertions.
Apply the same fix in `@test/runtime-current-account.test.ts` around lines 351 -
376: Covers the missing future-startedAt branch and related timestamp-boundary
assertions.
In `@lib/runtime/runtime-current-account.ts`:
- Around line 150-176: Bound the synchronous status-file scan in
readAppRuntimeHelperStatus and its helper listAppRuntimeHelperStatusPaths, using
a short-lived cache or bounded scan so repeated dashboard reads avoid unbounded
I/O while preserving selectRuntimeHelperStatus behavior. Handle concurrent
status-file deletion and Windows EBUSY without throwing, and add Vitest coverage
for repeated reads, those filesystem races, and multiple stale per-PID files in
the existing runtime account tests.
In `@scripts/codex.js`:
- Around line 3987-4067: Update createRuntimeRotationAppHelperOwnerLivenessCheck
and its callers so the identity recheck interval is derived from the resolved
idle window or an explicit environment override instead of remaining fixed at
APP_RUNTIME_HELPER_OWNER_IDENTITY_RECHECK_MS. Thread the interval through the
helper construction while preserving the existing three-state verdict and
single-flight asynchronous probe behavior.
- Around line 3937-3950: Update readProcessStartTimeMs and
readProcessStartTimeMsAsync in scripts/codex.js at lines 3937-3950 to return
null immediately on process.platform === "win32", avoiding ps execution while
preserving existing behavior elsewhere. Update the degraded-check row in
docs/development/ARCHITECTURE.md at line 206 to state that Windows has no
process start-time source, uses bare liveness checking, and is bounded by the
24-hour lifetime ceiling.
- Around line 4151-4279: Extend the regression coverage for
sweepStaleRuntimeRotationAppHelperMetadata beyond transient EBUSY retries:
verify a replacement file whose mtime changes between classification and removal
survives, and verify permanent EBUSY exhaustion is swallowed while the file
remains for a later sweep. Also update the stale launcher-order comment near the
existing test to state that the helper is spawned before the synchronous sweep,
with stdout handling and launch timeout setup afterward.
In `@test/app-bind.test.ts`:
- Around line 1141-1241: Add a regression test for unbindCodexAppRuntimeRotation
that creates more dead per-PID helper records than the configured unbind
concurrency limit, verifies all records and owner files are removed, and
observes that helper-stop operations never exceed the configured in-flight
bound. Reuse the existing per-PID status-file setup and the implementation’s
pool-limit symbol rather than hardcoding a duplicate limit.
- Around line 1177-1241: Add a variadic withDeadPids helper in the owned-PIDs
test utility that spawns the requested number of independent dead processes,
reaps them all before invoking the callback, and passes their PIDs as an array.
Refactor the multi-PID fixtures around unbindCodexAppRuntimeRotation and the
corresponding runtime-current-account test to use this helper, flattening the
nested withDeadPid scopes while preserving all existing assertions and setup.
In `@test/codex-bin-wrapper.test.ts`:
- Around line 3443-3454: Replace the inline sleeper creation, SIGKILL, and
polling logic in the affected test with the existing withDeadPid helper from
owned-pids.ts. Keep the current dead-PID assertion inside the helper’s callback,
remove the unnecessary Number coercions, and preserve the existing
cleanup/finally structure.
- Around line 734-745: Gate the identity-specific EPERM test that depends on
readOwnProcessStartTimeMs with it.skipIf(process.platform === "win32"). Keep the
existing non-Windows test behavior unchanged and do not alter the separate
Windows fallback coverage.
In `@test/helpers/owned-pids.ts`:
- Around line 20-34: Close the parent-side stdin pipe when reaping the child:
update waitForExit and the corresponding live/dead PID helper cleanup paths to
destroy child.stdin after the child exits. Preserve the existing exit/signal
checks and exit-event waiting behavior.
- Around line 36-50: Update withDeadPid so it revalidates that the captured PID
is still dead immediately before invoking run, using the existing
process-liveness mechanism; if the PID has been recycled, fail the fixture with
a clear error instead of passing it to callers. Keep the child spawn, kill, and
waitForExit sequence unchanged.

docs/**/*: Runtime config source selection is resolved in this order.
After a config source is selected, environment variables override individual runtime settings.
A set-but-missingCODEX_MULTI_AUTH_CONFIG_PATHis ignored for load until the file is created; the next save still writes to that path when the env var is set.
IfCODEX_HOMEis set to a non-default directory, multi-auth resolves strictly to$CODEX_HOME/multi-authwithout scanning other roots for existing pools.
Package install scripts stay side-effect-free (postinstall prints a short notice only).
The official CLI credential store is pinned tocli_auth_credentials_store = "file"in~/.codex/config.toml, so front-ends that exec the official binary directly stop triggering macOS login-keychain prompts.
It never runs npm install or update commands for you.
The official app files are not patched.
The proxy preserves request bodies and streaming responses, replaces outbound auth headers with the selected managed account, and rotates to another account before response bytes are streamed when it sees rate limits, server errors, network failures, or refresh failures.
It removes hop-by-hop headers, private account metadata headers, and stale decodedcontent-encodingfrom client responses.
docs/**/*:codex-multi-authis local-first: account/session state is stored on your machine under the configured runtime root.
Runtime rotation uses loopback-only local HTTP listeners.
The optional local bridge is also loopback-only and exposes only/health,
/v1/models, and/v1/responses.
It requires a local bearer token by default.
The token file stores SHA-256 hashes, not plaintext tokens.
Raw body logs may contain sensitive payload text. Treat logs as sensitive data and rotate/delete as needed.

Timestamp: 2026-06-04T06:14:18.093Z
Learning: In ndycode/codex-multi-auth, do not flag explicit imports from "vitest" (e.g., describe, it, expect, beforeEach/afterEach, etc.) in test files as issues—even if the Vitest config sets `globals: true`. The repo’s established convention is to keep these imports for consistency with neighboring tests; removing them would make files outliers.

Timestamp: 2026-06-04T06:14:24.975Z
Learning: In ndycode/codex-multi-auth test files (e.g. `test/*.test.ts`), when creating V3 storage fixtures for accounts, it’s an intentional convention to use `as never` for deliberately minimal stored-account objects that only include `refreshToken`, `addedAt`, and `lastUsed`. Do not treat `as never` here as a type-safety problem: optional/other fields are expected to be populated by the runtime during execution, and the cast is used solely to keep the fixture minimal and consistent across existing tests.

📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value
staleness window is coupled to a heartbeat constant that lives in another file and can be overridden below 60s.
the doc block asserts the publish path heartbeats "at least once per APP_RUNTIME_HELPER_STATUS_HEARTBEAT_MS (60s)". the actual heartbeat is Math.min(APP_RUNTIME_HELPER_STATUS_HEARTBEAT_MS, idleTimeoutMs, detachedIdleMs) in scripts/codex.js:4420, so the real cadence is at most 60s. that direction is safe for this reader, and both defaults are far above 60s.
the risk is the reverse edit: raise APP_RUNTIME_HELPER_STATUS_HEARTBEAT_MS in scripts/codex.js and this 10-minute window silently starts declaring live helpers dead, with no compile-time or test-time link between the two numbers. the wrapper cannot import from lib/ before dist/ exists, so a shared constant is not available — but a comment naming the file and a test asserting RUNTIME_HELPER_STATUS_STALE_MS >= 10 * <wrapper heartbeat> would fail loudly instead.
no code change required if you would rather pin it with an assertion in the suite above.

Two of these were documentation this PR had itself made wrong: moving the metadata sweep after `spawn()` invalidated a claim in ARCHITECTURE.md and a comment in the wrapper test that both still said "before". Behaviour: - `ps` does not exist on Windows, so `readProcessStartTimeMs` and its async twin could only ever fail there — once per launcher launch and up to `probeBudget` times per sweep, each one a process spawn that learns nothing. Both short-circuit on win32 now. Windows runs owner liveness on bare `kill(pid, 0)` and the 24h ceiling is what bounds a leak there; the "degraded check" row says so instead of implying it is rare. - The owner-identity recheck was pinned at 60s. `lastIdentityVerdict` starts optimistic, so the first tick reports the owner alive while the probe is in flight — deliberate against a 12h timeout, but the lifecycle tests compress the window to 250ms, where a 60s recheck is longer than the whole thing under test and the flip came down to probe timing. The interval now scales off the resolved idle/detached window. Production is unchanged: both defaults are hours. - `mapWithConcurrency` retired a runner on an `undefined` item rather than skipping it. Unreachable today — `items` is `string[]` — but the failure mode it guards is "helpers left running while the user is told the app was unbound", so only running past the end ends a runner. - The orphan owner pass preserved a live-PID owner file without a word, while every other preserve in that function warns. Telling "a helper is starting right now" from "the PID was recycled" needs the recorded-start-time comparison the launcher sweep does and unbind has no equivalent of; that stays a scope decision, but not a silent one. Fixtures: - Windows allocates PIDs from a pool rather than a monotonic counter, so `withDeadPid`'s "a just-exited PID is not reused" did not hold there — and its callers assert dead-PID cleanup on every platform. Deadness is re-asserted immediately before the PID is handed over, turning a rare Windows-only flake in a cleanup test into an immediate fixture error. - The parent end of the stdin pipe is destroyed on reap; `exit` fires before stdio teardown and some fixtures hold 16 at once. - The hand-rolled spawn/SIGKILL/poll copy in the wrapper test uses `withDeadPid`, which waits on `exit` instead of polling. - The EPERM owner-liveness test is win32-skipped: it sources the owner start time from `ps`, so on Windows the env var was empty, the identity branch never engaged, and it exercised bare liveness under a name claiming otherwise. - Nested `withDeadPid` scopes flattened via `withDeadPids`. Coverage: - `UNBIND_HELPER_CONCURRENCY` is exported and observed. With three records any pool width behaved identically, so an edit to `Infinity` would have shipped green; a fixture now runs 2x the bound in live helper records through unbind and measures peak in-flight at the `verifyProcessIdentity` seam. - test/app-helper-selection.test.ts covers the four selector predicates directly — non-positive/fractional PIDs, every terminal state, the staleness boundary either side by 1ms, null `updatedAt`, `startedAt` inside and outside the clock tolerance, recency in both input orders. - The staleness window is pinned to the wrapper's heartbeat. The wrapper cannot import from `lib/`, so nothing linked the two numbers; the test reads the constant out of `scripts/codex.js` and asserts ten heartbeats still fit inside the window. - A permanently locked metadata file is asserted survivable rather than assumed: the launch still exits 0 and the file waits for the next sweep. Not taken: a cache for the synchronous helper-status scan. It is pre-existing (#664 introduced the per-PID scan) and unchanged here; the menu loop blocks on user input between iterations, and the accumulation that would make it hurt is what this PR bounds. A time-based cache would show stale account state in the UI it is meant to speed up. Still uncovered: the mtime guard's negative path — a file replaced between classification and deletion. Forcing a write into that window needs another production test hook, which is too high a price for a microseconds-wide race.

Declined"Bound the synchronous helper-status scan" ( The scan is pre-existing (#664 introduced per-PID files); this PR does not change its cost. The menu loop it cites blocks on user input between iterations, so a readdir plus a few reads per interaction is not a real cost unless hundreds of stale files have accumulated — which is precisely the condition this PR bounds, via the launch sweep and the new unbind reclamation. Fixing the population is the right layer. A time-based cache in a status reader would also make the interactive menu show stale account state, which is a behaviour regression in exactly the UI the change is meant to speed up. Capping the scan would be worse — silently ignoring live helpers. One verification caveatThe mtime-guard's negative path (a file replaced between classification and deletion) is still uncovered. Its positive path is covered by every existing sweep test, but forcing a write into that window needs a new production test hook, and I judged an eighth fault injector too high a price for a guard against a microseconds-wide race.

The suite pins individual predicates with two or three records. That is not the shape the #663 machine was in — 183 live helpers, 701 owner files, one shared status file rewritten ~183 times a second — and none of the existing tests would notice a fix that works for three records and falls over at three hundred. Sixteen tests, split by what they need: test/zz-stress-helper-lifecycle.test.ts runs everywhere and drives the library surface directly — - unbind over 150 dead records with owner files, 100 orphaned owner files with no status record, and 6 live helpers whose ownership cannot be verified: everything provably dead reclaimed, every live record preserved, one warning per preserved record. - a directory of malformed metadata: truncated JSON, empty, whitespace, array, bare string, null, bare number, negative/fractional/zero/string/ unsafe-integer PIDs, non-numeric startedAt, missing and foreign `kind`, a 2 MB record past the sanity cap, and garbage owner files. Neither unbind nor the readers may throw — unbind runs during `uninstall`. - filesystem shapes that are not plain files: a directory where a status file goes, a directory where an owner file goes, a symlink to a real record, a broken symlink. `statSync` succeeds on all of them, so a reader that trusts it throws EISDIR inside `rotation status`. - readers hammering the directory while unbind deletes underneath them: every read is existsSync/statSync/readFileSync, so a file removed between any two steps has to degrade to "no record", never to an exception. - unbind idempotent across three rounds, and four concurrent unbinds over one directory. - the concurrency bound held across five back-to-back unbinds, checking the pool does not leak a slot per invocation. - the selector against 200 dead records carrying the *freshest* timestamps plus a live-but-stale one and 8 live-and-fresh: recency alone would pick wrong on both counts. - selection deterministic across 50 deterministic shuffles, because readdir order differs by filesystem and selection must be a function of the records. - every record aging out at the staleness boundary as time marches forward. - the filename contract against 16 near-miss names, and a round-trip over eight PID magnitudes. The wrapper-driven tests live in test/codex-bin-wrapper.test.ts because they need its fixtures, and are POSIX-only like the rest of the lifecycle suite — - metadata stays bounded across 30 launch/exit cycles. The pre-fix behaviour was one owner file per launch kept forever; the property is that the count is a function of helper overlap, not of how many times the loop ran. - 10 concurrent helpers each publish their own per-PID file naming their own PID, none overwriting another, none reaping a sibling. This is defect 3 in #663. - the reap matrix: owner-alive, owner-dead-never-served, owner-dead-served, no-owner-recorded, and owner-dead-socket-held, all running at once and asserted as a set, so a rule firing on the wrong configuration reads as a divergence rather than a single red test. - a launcher sweeping 700 pre-existing stale files, reclaiming the lot without pushing past the launch handshake bound. Mutation-checked, each against the test that should catch it: removing the never-served gate and collapsing the unknown-owner verdict both fail the reap matrix; removing the orphan owner enumeration fails the scale test; disabling the launcher sweep fails the 700-file test; unbounding the unbind pool fails the concurrency test. The pristine tree passes all fifteen. Two fixes to the fixtures themselves, both found by the stress work: - `withDeadPids` spawned every child at once. The stress fixtures ask for hundreds, and that many simultaneous spawns can hit a process-table or fd limit — surfacing as a fixture error indistinguishable from the bug under test. Batched at 32. - the launch-cycle assertion was `peak < cycles`, which only discriminates at the exact worst case. Tightened to a ceiling well under it.

Deep stress pass over the implementation, pushed as The existing suite pins individual predicates with two or three records. That is not the shape the #663 machine was in — 183 live helpers, 701 owner files — and nothing here would have noticed a fix that works for three records and falls over at three hundred.

Worth stating plainlyThe stress testing did not find a bug in the implementation. Everything held at every scale and under every hostile input. That is a real result, but it is weaker evidence than "found and fixed problems" — the honest read is that the implementation survived what I could think to throw at it, with the mutation matrix as evidence the throwing was real. Unchanged from the previous round: the mtime guard's negative path is still uncovered, for the same reason. Verification

In `@test/codex-bin-wrapper.test.ts`:
- Around line 7783-7795: Update the stress-test assertions around
countHelperMetadata so they require evidence that helper metadata was created,
such as a positive peak or final owner/status count, while retaining the
existing upper bounds that detect accumulation. Ensure the assertions fail when
the launch path creates no helpers, without weakening the cycle-overlap limits.
- Around line 7705-7723: Update countHelperMetadata so its readdirSync catch
returns zero counts only for an ENOENT error, and rethrow all other errors
instead of treating them as empty results. Preserve the existing metadata
counting behavior for successfully read directories.
- Around line 7970-7977: Update the test around the reaped helper to locate the
expected case by its label rather than using the positional running[1] entry.
Assert that the labeled helper exists, then unconditionally read its status and
verify state is "owner-gone"; do not guard the assertion with an if (reaped)
check.
- Around line 7955-7968: Update the process-aliveness assertions to pair each
case with its corresponding running helper instead of defaulting a missing
helper PID to 0; preserve the expected labels and alive comparisons while
ensuring missing entries cannot be reported as alive. Also correct the nearby
header comment to describe the five configurations in cases.
In `@test/helpers/owned-pids.ts`:
- Around line 100-113: Update waitForExit to handle child-process error events
as well as exit, ensuring failed spawns cannot leave cleanup pending. Validate
child PIDs before starting batch cleanup, and apply the same ordering and
handling in withLivePids. Add deterministic coverage for concurrent failed-spawn
cleanup and Windows named-pipe cleanup.

Learning: The duplicated runtime-helper selection logic in `lib/codex-manager/commands/rotation.ts` and `lib/runtime/runtime-current-account.ts` was introduced in PR `#664`. A follow-up change should centralize the selector and verify process identity, because `rotation status` can otherwise select different helpers for its status line and account markers. PR `#665` only adds `owner-gone` to a terminal-state comment and does not change this behavior.

Learning: In `scripts/codex.js`, runtime helper owner identity uses the owner PID plus a POSIX `ps` process-start-time comparison. On Windows, where that identity cannot be read, the owner-liveness check intentionally falls back to bare PID liveness. `test/codex-bin-wrapper.test.ts` must use a genuinely dead PID, rather than a mismatched start time, to test detached-helper reaping on Windows.

Learning: In `scripts/codex.js`, runtime helper owner identity uses the owner PID plus a POSIX `ps` process-start-time comparison. On Windows, where that identity cannot be read, the owner-liveness check intentionally falls back to bare PID liveness. `test/codex-bin-wrapper.test.ts` must use a genuinely dead PID, rather than a mismatched start time, to test detached-helper reaping on Windows.

Learning: In this repository, the liveness probes in `lib/runtime/app-bind.ts`, `lib/runtime/runtime-current-account.ts`, and `lib/codex-manager/commands/rotation.ts` treat only successful `process.kill(pid, 0)` calls and `EPERM` errors as live processes. Other errors, including `EINVAL` and `ESRCH`, classify the PID as dead. `test/codex-bin-wrapper.test.ts` mirrors this behavior.

Learning: In ndycode/codex-multi-auth, do not flag explicit imports from "vitest" (e.g., describe, it, expect, beforeEach/afterEach, etc.) in test files as issues—even if the Vitest config sets `globals: true`. The repo’s established convention is to keep these imports for consistency with neighboring tests; removing them would make files outliers.

Learning: In ndycode/codex-multi-auth test files (e.g. `test/*.test.ts`), when creating V3 storage fixtures for accounts, it’s an intentional convention to use `as never` for deliberately minimal stored-account objects that only include `refreshToken`, `addedAt`, and `lastUsed`. Do not treat `as never` here as a type-safety problem: optional/other fields are expected to be populated by the runtime during execution, and the cast is used solely to keep the fixture minimal and consistent across existing tests.

All five findings are against the stress tests added in the previous commit, and three of them are defects in the tests rather than nits. The serious one: the launch-cycle test passed if no helper was ever created. Every assertion in it was an upper bound, so a launch path that silently stopped publishing metadata — a wrong env gate, a proxy fixture that never engaged, `app .` short-circuiting on the fake bin — left every count at zero and the test green, while proving nothing about the accumulation it exists to guard. That is the same defect class as the unexercised selector branch this PR fixes for #668, in the test written to guard against it. It now probes first: one launch with a long idle window, asserting helper metadata actually appears, and that probe helper is torn down before the measurement loop starts. The loop additionally records whether it ever observed a helper, and asserts it did. Verified by mutation: stubbing out both metadata writers in the wrapper now fails the test instead of passing it. The rest: - `waitForExit` waited only on `exit`. A child that never spawns emits `error` and never `exit`, so the promise stayed pending forever — and since the batched helpers await a whole batch concurrently, one failed spawn stalled every sibling and hung the run rather than failing it. It now settles on either event, and the batch is reaped before the PIDs are validated so a throw cannot leak the siblings that did start. - `countHelperMetadata` swallowed every readdir error and reported zero. Only ENOENT is a legitimate zero; anything else — a permissions change, a path that is not a directory — was being reported as a clean sweep, which the upper-bound assertions accept happily. Narrowed to ENOENT, rethrowing the rest. - The reap matrix indexed `running[index]?.ready.pid ?? 0` and passed the fallback to `isProcessAlive`. On POSIX `kill(0, 0)` probes the caller's own process group and succeeds, so a missing helper would have read as alive — and four of the five cases expect alive. Zipped off `running` instead, with the length pinned. - The same test hardcoded `running[1]` as the reaped case and guarded the assertion with `if (reaped)`, so reordering `cases` would have asserted `owner-gone` against a helper meant to survive, and a missing entry would have skipped the only assertion proving *why* the helper died. Looked up by label and asserted unconditionally. The header comment said "four configurations" over a list of five. test/owned-pids-helper.test.ts covers the helpers themselves, including a direct assertion that a child which fails to spawn signals via `error` — the premise the hang fix rests on — with a timeout well inside vitest's so a regression reads as a failure rather than a stuck suite.

Round 2 addressed in The serious one: the launch-cycle test passed if no helper was ever createdCorrect, and it is the worst kind of miss — every assertion in that test was an upper bound, so a launch path that silently stopped publishing metadata would leave every count at zero and the test green while claiming to guard the #663 accumulation. That is the same defect class this PR fixes for #668 (an unexercised selector branch), reproduced in the test written to guard against it. My own mutation matrix did not catch it, because the mutation that disabled the sweep was caught by the 700-file test rather than this one. Fixed by making the fixture prove itself before it measures: one probe launch with a long idle window asserting helper metadata actually appears, that probe helper torn down before the loop starts, and the loop separately recording whether it ever observed a helper. Mutation-verified — stubbing out That mutation passed green before this commit.

- Around line 80-107: Update the child-spawn test to exercise the owned-PIDs
helper failure path rather than attaching listeners directly to a spawned
process. Add or reuse an injectable child factory seam, invoke withDeadPids with
a child whose spawn emits error without exit, and assert that the helper rejects
before the local timeout while keeping the test deterministic.
- Around line 91-106: Update the Promise.race cleanup in the test to retain the
timeout handle and place clearTimeout together with child.stdin?.destroy() in a
finally block, ensuring cleanup runs after the race regardless of its outcome.

Timestamp: 2026-08-11T20:56:30.727Z
Learning: The duplicated runtime-helper selection logic in `lib/codex-manager/commands/rotation.ts` and `lib/runtime/runtime-current-account.ts` was introduced in PR `#664`. A follow-up change should centralize the selector and verify process identity, because `rotation status` can otherwise select different helpers for its status line and account markers. PR `#665` only adds `owner-gone` to a terminal-state comment and does not change this behavior.

Learning: In `scripts/codex.js`, runtime helper owner identity uses the owner PID plus a POSIX `ps` process-start-time comparison. On Windows, where that identity cannot be read, the owner-liveness check intentionally falls back to bare PID liveness. `test/codex-bin-wrapper.test.ts` must use a genuinely dead PID, rather than a mismatched start time, to test detached-helper reaping on Windows.

Learning: In ndycode/codex-multi-auth test files (e.g. `test/*.test.ts`), when creating V3 storage fixtures for accounts, it’s an intentional convention to use `as never` for deliberately minimal stored-account objects that only include `refreshToken`, `addedAt`, and `lastUsed`. Do not treat `as never` here as a type-safety problem: optional/other fields are expected to be populated by the runtime during execution, and the cast is used solely to keep the fixture minimal and consistent across existing tests.

Learning: The duplicated runtime-helper selection logic in `lib/codex-manager/commands/rotation.ts` and `lib/runtime/runtime-current-account.ts` was introduced in PR `#664`. A follow-up change should centralize the selector and verify process identity, because `rotation status` can otherwise select different helpers for its status line and account markers. PR `#665` only adds `owner-gone` to a terminal-state comment and does not change this behavior.

Learning: In the ndycode/codex-multi-auth repo, uniqueness tests for crypto-backed nonce/ID generators (e.g., `tempFileNonce()` and `tempPathFor()` in `test/temp-path.test.ts`) intentionally draw from the real CSPRNG (`node:crypto.randomBytes`) rather than a forced unique sequence through a mock. Flagging these as nondeterministic is incorrect: collision probability across 200 draws from a 2^32 space is ~4.7×10^-6 per run (~1 in 200,000 CI runs), which is below any actionable flake threshold. The deterministic-tests guideline applies to clocks, ordering, network and filesystem races — not to astronomically-unlikely CSPRNG collisions. Mocking `randomBytes` to a pre-made unique sequence would verify only the mock, not the implementation, and would not catch regressions where the nonce stops using the CSPRNG (e.g., constant stub or truncated suffix).

When `pinnedIndex` is null/undefined, `pinnedAccountIndex` is set to null but the message still says "Pinned account 1 is currently unavailable…". The fix (null index renders as "The pinned account is currently unavailable…" with no numeric index) is tracked in stacked PR `#546` alongside an update to the contradictory expectation in `test/issue-474-pin-honored.test.ts`.

The test added for the hang fix installed its own `error` listener and asserted what node does with a child that never spawns. It never called `withDeadPids`, `withLivePids` or `waitForExit`, so deleting the handling it was written to protect left it green. It verified nothing. `OwnedPidOptions.spawnChild` is the seam that makes the real path reachable: the failure only occurs for a child that never spawns, which cannot be produced by spawning a working binary. Three tests now drive the helpers themselves through a factory that always fails, each bounded well inside vitest's own timeout so a regression reads as an assertion failure rather than as a suite that sits there until the runner gives up. Rewriting it that way immediately failed, and the reason was a second defect in the helper rather than in the test: `child.kill()` on a child that never spawned throws instead of no-opping — `EINVAL` on Windows — and that throw escaped the cleanup loop before the batch helpers could report why the batch was unusable. Callers saw `kill EINVAL`, and on a partial failure the real diagnosis was masked entirely. Signalling now goes through a guarded `killChild`, and the singular helpers reap their child before reporting a failed spawn rather than leaking it. Mutation-checked the way the previous version should have been: removing the `error` listener from `waitForExit` makes all three tests report `HUNG` at exactly their 5s budget. Also clears the race timer in a `finally`. It was left referenced after the race resolved, holding worker shutdown open for its full five seconds.

File: lib/codex-manager/commands/rotation.ts:576-587
Timestamp: 2026-08-11T20:56:30.727Z
Learning: The duplicated runtime-helper selection logic in `lib/codex-manager/commands/rotation.ts` and `lib/runtime/runtime-current-account.ts` was introduced in PR `#664`. A follow-up change should centralize the selector and verify process identity, because `rotation status` can otherwise select different helpers for its status line and account markers. PR `#665` only adds `owner-gone` to a terminal-state comment and does not change this behavior.

Learning: In `scripts/codex.js`, runtime helper owner identity uses the owner PID plus a POSIX `ps` process-start-time comparison. On Windows, where that identity cannot be read, the owner-liveness check intentionally falls back to bare PID liveness. `test/codex-bin-wrapper.test.ts` must use a genuinely dead PID, rather than a mismatched start time, to test detached-helper reaping on Windows.

Other errors, including `EINVAL` and `ESRCH`, classify the PID as dead. `test/codex-bin-wrapper.test.ts` mirrors this behavior.

On Windows, where that identity cannot be read, the owner-liveness check intentionally falls back to bare PID liveness. `test/codex-bin-wrapper.test.ts` must use a genuinely dead PID, rather than a mismatched start time, to test detached-helper reaping on Windows.

Learning: In this repository, the liveness probes in `lib/runtime/app-bind.ts`, `lib/runtime/runtime-current-account.ts`, and `lib/codex-manager/commands/rotation.ts` treat only successful `process.kill(pid, 0)` calls and `EPERM` errors as live processes. Other errors, including `EINVAL` and `ESRCH`, classify the PID as dead. `test/codex-bin-wrapper.test.ts` mirrors this behavior.

Learning: In ndycode/codex-multi-auth test files (e.g. `test/*.test.ts`), when creating V3 storage fixtures for accounts, it’s an intentional convention to use `as never` for deliberately minimal stored-account objects that only include `refreshToken`, `addedAt`, and `lastUsed`. Do not treat `as never` here as a type-safety problem: optional/other fields are expected to be populated by the runtime during execution, and the cast is used solely to keep the fixture minimal and consistent across existing tests.

A follow-up change should centralize the selector and verify process identity, because `rotation status` can otherwise select different helpers for its status line and account markers. PR `#665` only adds `owner-gone` to a terminal-state comment and does not change this behavior.

Three of the four entry points had a failed-spawn regression; this one did not, and its branch was changed in the same commit as the others. Its cleanup runs from a `finally`, which is precisely where an unguarded `kill` throw would have replaced the reported reason with its own — the bug the guarded `killChild` exists to prevent.

Addressed in Correct, and I had missed this comment entirely on the previous pass — not because it was hidden, but because I was enumerating review comments by timestamp window. My round-3 query filtered On the substance: three of the four entry points had a failed-spawn regression and this one did not, despite its branch changing in the same commit. Windows For whoever picks this up: the running tally across this PR is four review rounds that each found something real, all of them after my own verification had reported green. Rounds 2 through 4 were entirely in the tests I wrote, including one that passed vacuously and one that asserted node's behaviour rather than the fix it was written for — and rewriting that second one immediately exposed a genuine |
Version and documentation scaffold only. Release notes and the CHANGELOG entry follow after publish, per the usual split. Test stats move to 5459 tests across 341 files. The skipped count rises from 4 to 19 because the helper-lifecycle coverage added in #669 is `skipIf(win32)` — those tests run on POSIX and are counted as skipped on the platform these numbers are measured on.

Summary
codex appproxy after 15 idle minutes.What Changed
#665's detached reap could kill a live
codex appsessioncodex apprelies on the detach grace rather than an explicitdetachOnExit, so its launcher exits inside the 5s window and the helper's owner is dead from the first tick. From then on the only thing between the desktop app and a dead proxy wascountOpenConnections() === 0.The proxy never sets
server.keepAliveTimeout, so Node closes idle client sockets after its 5s default. A user who stops typing for the length of the detached window has zero sockets and no new requests — the helper exitsowner-gone, and the next message gets ECONNREFUSED against a dead localhost port with nothing left to restart it. Pre-#665 that session survived the full 12h idle timeout.The detached window now only reaps a helper that has never served a request. Every leaked helper in #663 had
totalRequests: 0, so the leak is entirely a never-served phenomenon and the narrower gate closes it in full; a helper that served anything was genuinely handed off and falls back to the idle timeout and #664's 24h ceiling.This changes #665's stated contract ("traffic carries a stranded helper; once traffic stops, reap it") and rewrites the test encoding it. The trade: a served-then-abandoned helper lives up to 12h instead of a working desktop session being killed after 15 idle minutes.
Two more in the same tick:
unknownowner ≠ dead owner.createRuntimeRotationAppHelperOwnerLivenessCheckreturnedfalsewhen no owner PID was recorded, and the tick read that as "confirmed dead" — so a helper invoked directly (the documented reproduction in [bug] runtime rotation app helpers leak past their idle timeout; all helpers trample one shared status file #663) or spawned by a pre-upgrade launcher started the detached clock on its first tick and reaped itself 15 minutes later. The verdict is now three-valued;unknownfires neither branch, which is what the pre-fix(codex): stop runtime helpers from leaking past their idle timeout (#663) #664ownerPid && isAlive(ownerPid)guard did.idleExpiresAtwent stale after the owner died.publishTokenzeroes it, so the published deadline only caught up on a heartbeat pinned to the idle window —rotation statusadvertised a 12h deadline for a helper seconds from exiting, and under a shortDETACHED_IDLE_MSoverride never caught up. The heartbeat now folds in the detached window.#666 — owner files orphaned by unbind
Two branches removed a status file without checking
helperOwnershipMatchesbut gatedremoveHelperOwneron it. On a token mismatch, unbind deleted the status file and keptruntime-rotation-app-helper-owner.<pid>.json— and because unbind enumerated status paths only, nothing ever rediscovered it.The issue asks for a deliberate choice between the conservative and decisive policies. Decisive: a proven-dead PID means both files describe a process that no longer exists, so both go. That is what the launcher-side sweep already does, so the two paths now agree. The ownership gate still stands where it matters — a live PID whose ownership cannot be verified is preserved with a warning, untouched.
Unbind now also enumerates owner files, so a pre-existing orphan is reclaimed instead of being unreachable. A live PID's owner file is left alone.
§2 of the issue is wrong and needs no code change. "Helper unlinks are not retried on Windows" —
unlinkIfExists(lib/runtime/app-bind.ts:300) already wrapsunlinkinwithFileOperationRetry, so thehelperCleanupPathsloop does get retries. Worth closing that half without a diff.#667 — one selector, and it now checks identity
Both hand-rolled copies are gone;
rotation.tsandruntime-current-account.tsuseselectRuntimeHelperStatusfrom the newlib/runtime/app-helper-selection.ts.printRotationStatusmade the drift concrete by selecting twice either side of an awaitedprintCodexAppBindStatus— the liveness probes re-ran at a later instant, so a helper that exited during that await was named on the status line while a different one fed thecurrentmarker two lines down. It now selects once and threads onenowthrough the line, the count and the marker.For identity: status files now parse
startedAt, and liveness additionally requires the record to be fresh. A running helper republishes at least once per heartbeat (capped at 60s), so ten heartbeats of silence means the current holder of that PID did not write this file — exactly the stale-legacy-file-with-a-recycled-PID case.Freshness rather than a kernel start-time probe because both call sites are synchronous read-only status paths reached from the interactive menu as well as the CLI (
readAppRuntimeHelperAccountSignalis threaded throughcodex-manager.tsas a sync function), and apsper candidate is not something a status reader should pay. The wrapper, which can afford it, still probes start times.Also fixed here: both readers accepted any finite number as a PID, so a record carrying
-1234reachedprocess.kill(-1234, 0)— a POSIX process-group probe that succeeds on any busy machine and reports a nonexistent helper as live.app-bind.tsalready required a positive integer; these two now agree with it.#668 — test hygiene, and a fault injector that shipped
withDeadPid/withLivePidintest/helpers/owned-pids.ts).process.ppid→ an owned sleeper, killed infinally.CODEX_MULTI_AUTH_TEST_FAULT_INJECTION=1and a strict digits-only parse (Number.parseIntreads"2abc"as 2 and"1e3"as 1). Regression tests assert a production invocation ignores both a bare counter and a non-numeric one.resolveRuntimeHelperOwnerPath.Two more from the review
spawn(). It is synchronous and unbounded — readdir, areadFileSyncper live candidate,rmSyncwith a blocking backoff, boundedpsprobes — and the state it cleans up is exactly the state that makes it slow, so it sat in front ofcodex appand TUI startup. It now runs after the spawn, so the helper boots in parallel with it; the launch timeout is armed after it either way.Validation
npm run lintnpm run typechecknpm test— 338 files, 5419 passed, 15 skipped, 0 failures (Windows)npm test -- test/documentation.test.tsnpm run buildLinux coverage, because the helper-lifecycle tests are
skipIf(win32)and never run on the Windows box. In anode:22container as a non-root user with a freshnpm ci, every one of them executes and passes — includingkeeps a helper that has served traffic alive after its traffic stops,still reaps a stranded helper that never served a request, anddoes not start the detached clock for a helper launched without an owner PID.The same container run against unmodified #665 produces the identical 3 failures (
prefers Windows codex.exe over extensionless codex,skips self-referential codex wrapper entries on PATH) — pre-existing Windows-path tests that do not run correctly on Linux, untouched by this branch. Passing count goes 252 → 262.Every new regression test was mutation-checked: reverting the corresponding fix makes it fail. The one exception is the permanently-locked-metadata test, where removing the
catchhangs the launcher rather than producing a clean failure — load-bearing, but not a clean mutation result.Review round 1 (CodeRabbit, 16 comments): 15 applied, 1 declined — see the response comment below for the reasoning on each, including the two findings that caught documentation this PR had itself made wrong, and the one gap I left open deliberately.
