[P2] Make the replacement-generation test deterministic and align it with the locked writer contract
src/cli/bgRegistry.cleanup.test.ts:882-907
The new test deletes the reservation and immediately recreates it directly from_beforeReservationRemovalForTesting, then expects cleanup to report an identity mismatch (errors === 1). That expectation relies on the recreated file receiving a different(dev, ino). Filesystems may immediately reuse an inode: the focused test currently fails withExpected: 1; Received: 0becauseremoveCleanupArtifact()sees the reused identity and unlinks the replacement.The root cause is that the test treats filesystem inode allocation as a generation marker while also bypassing
withNameReservationLock, which normal reservation writers use. This does not demonstrate that supported writers can lose a replacement reservation, but it makes the new regression test nonportable and tests a different concurrency contract from production. Please revise the scenario to exercise the locked writer/cleanup interaction, or use deterministic synchronization/identity evidence that cannot be satisfied by immediate inode reuse. Keep the existing metadata-first cleanup order and the protection against removing a reservation that no longer belongs to the expired session.
Overall guidance
The current head has one confirmed issue, not a broad set of confirmed defects. The repeated review churn has nevertheless concentrated around one root problem: cleanup spans several independently persisted artifacts (metadata, stdout/stderr logs, terminal facts, and name reservations) while normal session creation/finalization and cleanup can interleave. Treat this as one lifecycle contract rather than a sequence of local unlink fixes.
Before another update, please write down and validate the intended ownership and ordering for each transition: create → reserve name/write metadata and logs → record terminal fact → release/reuse name → cleanup metadata/logs/reservation → reclaim leftover terminal facts. For each boundary, state what makes an artifact eligible, which operation serializes it, what happens on a partial failure, and how retry recovers without affecting a newly created session.
In particular, keep production concurrency tests on the actual synchronization path (withNameReservationLock) and make races deterministic with explicit hooks/barriers or durable generation evidence—not scheduling or inode-allocation assumptions. Cover both directions of a partial cleanup (metadata remains after an artifact failure, and terminal facts remain after metadata removal), then run the focused registry suite together with the scheduler integration tests. This should prevent further feedback from uncovering the same lifecycle contract one edge at a time.

Node.js official documentation fs.promises.symlink Windows Developer Mode type dir junction
💡 Result:
The Node.js fs.promises.symlink(target, path[, type]) documentation specifies that the type argument is used exclusively on Windows platforms [1][2]. It accepts three values: 'dir', 'file', or 'junction' [1][2]. Regarding your query on the relationship between these types, Windows Developer Mode, and system permissions: 1. Junctions vs. Directory Symlinks: Unlike standard symbolic links, NTFS junction points can only point to directories [1][2][3]. Attempting to use 'junction' to link a file will result in an error or an invalid link, as junctions are a specific type of directory-based reparse point [3]. 2. Windows Developer Mode and Permissions: - Creating standard symbolic links ('dir' or 'file' types) on Windows typically requires the "Create symbolic links" privilege [4]. By default, this privilege is restricted to users with administrative rights, but enabling Windows Developer Mode grants this capability to non-admin users [5]. - Junctions ('junction') do not require the "Create symbolic links" privilege and can generally be created without administrative elevation or Windows Developer Mode [4][3]. 3. Documentation Details: - If the type argument is omitted or set to null, Node.js will attempt to autodetect the target type and select 'dir' or 'file' accordingly [1][2]. - When using 'junction', Node.js automatically normalizes the target argument to an absolute path, as Windows junction points require absolute paths [1][2]. In summary, if you are encountering permission errors (EPERM) when creating symlinks, using 'junction' is a common workaround to avoid needing administrative privileges or Windows Developer Mode, provided you are linking a directory [5][4][3].

[P2] Reject parseable-but-invalid completion timestamps before deleting artifacts
src/cli/bgRegistry.ts:1187
The registry’s persisted-data validators currently requirefinishedAtonly to be a string, then the new retention path upgrades that to “valid” whenDate.parse()returns a finite number. That is not a safe corruption check: on the supported Node runtime,Date.parse("2026-02-30")silently normalizes to 2026-03-02 andDate.parse("0")resolves to an old date. Either value can therefore make a malformed terminal fact or completed metadata record look expired. Cleanup then removes its canonical stdout/stderr logs, matching reservation, metadata, and valid sibling terminal fact—the opposite of the PR’s stated malformed-artifact preservation behavior.Please address the root cause by defining one strict completion-timestamp validator for persisted background-session metadata and terminal facts, and use it at the destructive cleanup boundary (rather than treating
Date.parse()acceptance as validation). It should accept the canonical timestamp representation the registry writes and reject normalized or implementation-dependent input. Add regressions for parseable malformed values such as"2026-02-30"and"0", asserting that every artifact remains intact; retain the existing behavior for correctly serialized historical records.
UpdateHardened background-session retention cleanup so malformed persisted completion timestamps cannot make artifacts eligible for deletion. Addressed

[P3] Prevent retained terminal facts from being reused by a new session ID
src/cli/bgRegistry.ts:1319
The cleanup order is currently: remove the canonical logs and matching reservation, unlink the metadata at this line, then remove the natural/killed terminal facts. If a terminal-fact unlink fails, the metadata is gone but the fact is intentionally retained for the later orphan sweep. That makes the ID look available tocreateBackgroundSession(), because it only detects metadata collisions. IDs are generated from an eight-hex-character UUID prefix, so a later collision can register a new session with the old ID before that sweep runs. Its finalizer then hits the retained immutable fact, accepts it through theEEXISTpath, and returns it; because its PID belongs to the prior session, the new completion is not applied or persisted. Once the new process exits, status refresh can mark its metadatastale, which this cleanup intentionally preserves.Please address the lifecycle root cause rather than only special-casing the finalizer: an ID must remain unavailable while any terminal state for that generation remains, or terminal facts must carry and validate a generation identity that prevents an old fact from being accepted for a new session. Preserve the important existing guarantees: metadata-first partial cleanup must remain retryable, terminal facts must remain immutable, and malformed or unowned artifacts must remain conservatively untouched. Add a regression that forces terminal-fact removal to fail, creates a same-ID replacement before the orphan sweep, then verifies the replacement can durably record and later expose its own terminal outcome.
UpdateBackground-session cleanup now scopes persisted terminal outcomes and every stale mutation to the exact session generation, so a retained fact or delayed operation cannot affect a later same-ID session. Addressed

I found issues that need to be addressed before this is ready.
Overall guidance
The remaining problems have the same underlying shape: background-session lifecycle ownership is split across independent actors without a single durable reconciliation path. The child finalizer writes terminal facts, foreground CLI commands refresh metadata, cleanup removes old artifacts, and housekeeping decides when cleanup runs. Each part is individually defensive, but a transient failure or an ordering change between them can leave a session in a state that no later actor repairs:
- The child can know that it exited but fail to persist that fact because a foreground refresh temporarily owns the metadata lock.
- A foreground refresh can then persist
stale, which is deliberately excluded from retention cleanup. - Cleanup can correctly retain a running session at one point in time, but no later lifecycle event requests another sweep once that session finishes.
Please address this as a lifecycle/reconciliation problem rather than by adding isolated retries at the two reported call sites. Define a durable terminal-state handoff that survives expected races and process-exit constraints, and ensure it has a later consumer that converges the registry to its terminal state and applies retention policy. In particular:
- Keep terminal facts authoritative and generation-scoped, but make a temporarily contended finalization recoverable by a later process instead of silently terminally failing.
- Make the ownership/order contract explicit for finalization, refresh, cleanup, and session-ID reuse. A writer that observes an older generation must not mutate or delete a replacement, but it also must not strand the older generation forever.
- Treat retention as a lifecycle consumer, not only a startup sweep. It needs a safe opportunity to run after a session transitions to terminal state, especially with zero retention.
- Add end-to-end race tests that exercise the real handoffs: child exit while refresh holds the lock; completion after the first housekeeping sweep; restart/resume after an interrupted finalization; and same-ID/name reuse while cleanup is pending. The assertions should prove eventual convergence—not merely that one attempted write or cleanup call returned successfully.
The current filesystem validation and generation checks are valuable and should remain intact. The goal is not to weaken those guards for liveness; it is to provide a durable retry/reconciliation route that preserves them.
Findings
-
[P2] Do not lose exit finalization when the registry lock is briefly held
src/cli/bgRegistry.ts:2004
The root cause is applying the new metadata lock to the synchronousexitfallback withretries: 0. On a termination path that skips gracefulbeforeExitcleanup, another CLI can be insiderefreshBackgroundSessionStatuses()while it holds the same per-session lock.recordBackgroundSessionNaturalTerminationSync()then throws “Lock file is already being held”;bgFinalizerlogs that error and the exiting child has no retry opportunity. The concurrent refresh can persiststale, and subsequent refreshes skip stale records while retention cleanup intentionally excludes them, so the completed session’s metadata, name reservation, and logs remain indefinitely.Please address the root cause by ensuring completion is recorded durably even when that lock is briefly contended. Preserve the generation/ownership checks and do not make the process-exit handler wait unboundedly; a bounded handoff to retryable work or a completion record that can be safely persisted without losing the existing race protection would both satisfy the contract. Add a regression that holds the refresh/metadata lock through the synchronous fallback and proves a later registry pass converges on a terminal, retention-eligible session.
-
[P2] Make zero-day retention run after a background session completes
src/utils/cleanup.ts:602
The root cause is that this is the sole new cleanup call, butstartBackgroundHousekeeping()runs it only once per process. In a long-lived client, a session that is still running during that pass and exits afterward never gets another cleanup attempt: the 24-hour timer does not call this function, and neither natural nor explicit-kill finalization schedules one. That leaves its artifacts retained until a later client happens to run housekeeping, despite the newcleanupPeriodDays: 0contract saying completed background artifacts are removed after they finish.Please address the lifecycle rather than only the initial sweep: arrange for an eligible completion to receive a later cleanup opportunity, including when the client stays alive after its first housekeeping pass. Preserve positive retention periods, the invalid-settings skip guard, and the current safeguards that keep running, stale, malformed, and unowned artifacts intact. Add an integration regression that runs the initial cleanup while a session is live, completes it afterward with zero retention, and verifies that its artifacts are subsequently reclaimed in the same long-lived process.
UpdateBackground-session exit handoffs now survive metadata-lock contention, converge safely into terminal metadata, and receive recurring retention passes after a long-lived process has started. Addressed

[P2] Give short-lived zero-retention jobs a cleanup owner after exit
src/utils/backgroundHousekeeping.ts:59
The newly added reconciliation path has no initial pass: it only schedules this unref'd interval for 60 seconds later. A normal detached--bgchild can finish before then; its async/sync finalizer records a terminal fact, but neither finalizer requests retention cleanup. When the launcher and child both exit, the interval disappears with them, so there is no actor left to reconcile the fact or remove its metadata, logs, matching reservation, and terminal fact. The artifacts therefore remain until an unrelated later OpenClaude process happens to stay alive for a full interval, despitecleanupPeriodDays: 0promising removal after completion.Please address the lifecycle root cause rather than merely shortening the interval: terminal-state handoff and retention need a cleanup opportunity that survives the normal short-lived child/launcher lifetime. Preserve the invalid-setting guard, filesystem/ownership safeguards, positive retention behavior, and non-blocking exit semantics. Add an end-to-end regression that launches a short detached job with zero retention, lets both processes exit before the first scheduled pass, then proves its artifacts have been reclaimed without relying on a test-only manual interval callback.
UpdateZero-day background-session retention now has an exit-safe cleanup owner for short-lived and directly exiting jobs. Addressed

I found three issues that need to be addressed before this is ready. They share one lifecycle-design problem, so I recommend fixing them together rather than applying another set of route-specific patches.
Overall guidance
The repeated findings on this PR are coming from a missing end-to-end retention contract. Cleanup is now initiated from four execution contexts that do not bootstrap the same state:
- The normal background child has parsed the invocation's
--settingsand--setting-sourcesflags. - The detached cleanup worker starts as a fresh process with private PID markers, but no original argv and therefore no invocation settings state.
openclaude killdeliberately runs on a config-free management path.- Long-lived housekeeping runs recurring cleanup with whichever settings and process lifetime that interactive CLI happens to have.
All four contexts eventually call the same broad registry sweep, but no shared contract says which retention policy is authoritative, which process owns the cleanup opportunity, or whether a trigger needs prompt zero-day reconciliation versus an age-based periodic sweep. That makes each local fix vulnerable to the next bootstrap or lifecycle edge: the worker has ownership but loses policy provenance, kill has the terminal transition but cannot read policy, and housekeeping can recover missed work but does so by repeatedly scanning all retained history.
Please address that root cause with one narrow background-retention coordinator or equivalent explicit contract. It should receive enough validated context to answer these questions without relying on ambient process state:
- What triggered the pass: natural finalization, explicit kill, or periodic housekeeping?
- Which effective settings sources control the pass, including
--settings, inline settings JSON, and--setting-sourcesprecedence? - Does this trigger require prompt zero-day reconciliation, or only an age-based retention sweep?
- Which process owns the attempt, and what is the fallback when that process exits?
- How is work throttled across multiple OpenClaude processes, and what bounds apply to one pass?
The implementation does not need a broad registry or settings refactor. A focused solution could pass the original validated settings-source arguments into the worker, give the management route a narrow provider-free retention-settings loader, and split prompt reconciliation from positive-retention sweeping behind a cross-process throttle. The important part is to make policy provenance and cleanup ownership explicit once, then reuse that contract from all three triggers.
Please also add a production-path regression matrix rather than testing only the helpers in isolation:
- natural completion and explicit kill;
cleanupPeriodDaysvalues0and a positive value;- global settings and conflicting
--settings/--setting-sourcesoverrides in both directions; NODE_ENVunset, using the built CLI bootstrap path;- short-lived launcher/child processes with no manually invoked interval callback;
- more than one housekeeping process, with filesystem-operation counts or another assertion that proves work is globally throttled or bounded.
That matrix should make the lifecycle contract load-bearing and prevent another round where a test passes because it bypasses production configuration gates or manually calls a scheduler callback.
Findings
-
[P2] Keep the effective retention policy across the finalizer-to-worker handoff
src/cli/bgFinalizer.ts:195-200
startBackgroundSessionCleanupWorkerlaunchesprocess.execPathwith onlyprocess.execArgvand the CLI entrypoint. The original background child argv is not forwarded. In the fresh process, the cleanup-worker branch atsrc/entrypoints/cli.tsx:323-328enables the default config and returns beforeeagerLoadSettingsFromArgs(args)runs at lines 470-480. Consequently,cleanupBackgroundSessionsAfterFinalizationreads the worker's global/default settings rather than the effective settings under which the background invocation ran.This changes destructive behavior, not just diagnostics. With global
cleanupPeriodDays: 0and an invocation--settingsfile containingcleanupPeriodDays: 30, the worker sees0and deletes completed metadata, stdout/stderr logs, and terminal facts that the invocation would have retained. With the values reversed, the child requested zero-day cleanup but the worker sees the positive global value and returns without waiting or deleting.--setting-sourcescan produce the same mismatch by changing whether user/project settings participate at all.Fix the handoff contract rather than special-casing
cleanupPeriodDaysin one call site. The worker needs either the exact validated settings-source inputs or an explicit, validated retention-policy handoff that preserves the same precedence semantics and can still be rechecked after the owner/launcher wait. Add built-process tests for conflicting global/flag settings in both directions; a test with only the global settings file cannot detect this failure. -
[P2] Make zero-retention cleanup reachable from the config-free kill path
src/cli/bg.ts:1057-1062
The CLI intentionally dispatchesps,logs,attach, andkillbeforeenableConfigs()so local session management remains available without provider/profile/startup validation. After a successful terminal transition, this newkillHandlerblock callscleanupBackgroundSessionsAfterFinalization, whose first guard callsgetSettingsWithAllErrors()and thengetSettings_DEPRECATED(). In a production process on this fast path, those reads throwConfig accessed before allowed.. The broad catch suppresses the exception, the command printsKilled ..., and there is no remaining immediate cleanup owner.With global
cleanupPeriodDays: 0, the production path leaves the killed session's metadata and both logs in place. The added explicit-kill regression reports them removed only becauserunCleanupFixtureforcesNODE_ENV: 'test';getConfigbypasses its pre-enable guard in test mode, so the fixture cannot exercise the shipped bootstrap sequence.Please solve the bootstrap mismatch at the shared retention boundary. Keep management commands independent of provider validation and unrelated startup work, but give the cleanup coordinator a narrow supported way to resolve retention settings before it performs its guards. Do not merely widen this catch or duplicate a raw JSON read in
killHandler, because either approach leaves policy precedence inconsistent with the worker and scheduler paths. Add a built-CLI explicit-kill test withNODE_ENVabsent that proves the kill succeeds, zero-day artifacts are reclaimed, positive-retention artifacts remain, and a cleanup failure still does not replace the successful kill outcome. -
[P2] Separate prompt reconciliation from unbounded retained-history sweeping
src/utils/backgroundHousekeeping.ts:59-69
Every long-lived OpenClaude process now invokescleanupBackgroundSessionsInBackground()once per minute, regardless of whether retention is zero or the default 30 days. That function callsreconcileBackgroundSessionTerminalFacts()and thencleanupBackgroundSessionsBefore(). Both independently enumerate the entire metadata registry and read/validate each applicable session. The orphan path also materializes, filters, and sorts the entire terminal-fact directory before its nominal 256-entry cap is applied, so that cap limits only subsequent processing—not directory traversal, allocation, or sorting.The
runningboolean prevents overlap only inside one JavaScript process. Two interactive OpenClaude processes each perform their own full scans and acquire the same per-session locks every minute. Because the default policy intentionally retains 30 days of completed history and there is no registry-size bound, the recurring cost grows with valid retained history and is multiplied by concurrent CLIs. This changes the previous delayed/daily housekeeping model into sustained filesystem I/O and synchronous sorting during interactive use.The code comment says the minute cadence exists to give zero-day terminal facts a prompt later pass, so align the work with that purpose. Separate the cheap/prompt recovery trigger from positive-retention expiration, add a cross-process throttle or registry-level lease for recurring work, and make any allegedly bounded pass bounded before
readdirresults are fully materialized/sorted when the terminal directory can be large. Preserve the existing generation, inode, symlink, timestamp, and reservation safety checks. Add a multi-scheduler regression with a large retained registry that asserts one globally owned or genuinely bounded pass rather than merely invoking a captured interval callback and checking the per-processrunningflag.

I found four issues that need to be addressed before this is ready.
Overall guidance
The first three findings have the same root cause: background retention is implemented as several independently bootstrapped execution paths, but there is no single explicit contract for the policy they carry, the work each trigger owns, or how bounded work makes durable progress. Natural completion, explicit kill, minute recovery, and the daily age sweep all reach the registry from different process lifetimes and settings contexts. The latest changes fix several individual routes, but important behavior is still implicit in argv reconstruction, ambient settings state, one-shot housekeeping, and filesystem enumeration order. That is why new edge cases keep appearing as each route is exercised end to end.
Please address these as one retention-coordination problem rather than four isolated call-site patches. The shared contract should make the following properties explicit:
- Policy provenance and validation state. Every destructive pass needs the effective retention decision from its originating settings context, including the distinction between an absent policy, a valid policy, and an invalid policy that must fail closed. A handoff must not turn an invalid configuration into a valid reduced configuration. This does not require forwarding unrelated inline settings or secrets; a narrow validated policy descriptor or equivalent mechanism is sufficient if it preserves that distinction and can be safely rechecked after the worker waits.
- Trigger responsibility. Define which trigger performs prompt zero-day reconciliation, which performs the positive-retention age sweep, and which is only a recovery fallback. Natural completion and kill need an exit-safe opportunity; minute recovery should remain cheap and bounded; the daily owner should run the full age-based pass. Those responsibilities should be visible in one coordinator contract instead of emerging from unrelated timers and early returns.
- Durable bounded progress. A per-pass entry limit is not enough if every process starts from the same directory prefix. Any bounded fallback must carry or derive progress so repeated globally throttled passes eventually cover later entries, including after process restart and while earlier entries remain intentionally ineligible. A cursor, rotating partition, or another restart-safe scheme would work; the important requirement is eventual coverage without weakening the 256-entry bound or filesystem safety checks.
- Ownership transfer and failure cleanup. When a process or test helper launches detached work, ownership must remain with the launcher until all initialization that can fail has completed. Every error path before ownership transfer must terminate the detached process and wait for it to stop. After a successful transfer, exactly one caller should own cleanup.
- End-to-end contract tests. Add a compact matrix across natural completion, explicit kill, minute recovery, and daily retention for valid zero-day, valid positive-day, and invalid policy states. Include a permanently retained directory prefix, a process restart between bounded passes, and failures after a detached PID is known but before readiness. Assertions should prove eventual convergence or conservative retention through the production bootstrap path, not only that an individual helper returned successfully.
Please keep the existing safeguards: generation and inode revalidation, trusted-root and symlink checks, exact reservation ownership, invalid-policy fail-closed behavior, cross-process throttling, bounded minute work, and the rule that cleanup failure must not replace a successful kill outcome. The goal is to centralize the missing lifecycle contract, not to broaden cleanup or weaken its safety checks.
Findings
-
[P2] Preserve validation state across the cleanup-worker settings handoff
src/cli/bgFinalizer.ts:240
backgroundRetentionSettingsValue()parses inline--settingsand, whencleanupPeriodDaysis present, serializes a new object containing only that key. This loses validation errors contributed by every sibling setting. For example, the originating invocation{"cleanupPeriodDays":0,"permissions":{"defaultMode":"bogus"}}is an invalid policy and correctly retains all artifacts. The worker instead receives{"cleanupPeriodDays":0}, which is valid, so after the owner and launcher exit it can delete the completed session's metadata, stdout/stderr logs, matching reservation, and terminal fact. This exact transition frominvalid-policytoranis reproducible through the natural-finalization cleanup path.The root issue is that the handoff treats a lossy settings projection as though it were the original validated policy. Carry the policy's validation state and effective retention value across the boundary, or otherwise ensure the worker reconstructs the same retention decision and precedence semantics. Preserve the current secret-minimization goal: unrelated inline settings do not need to be forwarded, but their validation failures must remain capable of forcing cleanup to fail closed.
-
[P2] Make bounded recovery provide eventual progress past retained entries
src/cli/bgRegistry.ts:1617
Each minute recovery pass opens the metadata and terminal directories from the beginning and stops after the first 256 raw directory entries. Only after truncation does it filter for valid files and cleanup eligibility, and neither the registry nor the throttle records where the preceding pass stopped. If those first entries are running, recent, malformed, unreadable, or otherwise intentionally retained, every later pass examines the same prefix. An eligible completed session or orphaned terminal fact after that prefix can therefore remain forever, even though recovery continues to run once per minute. Repeated bounded passes reproduce zero progress; the existing 300-entry test succeeds only because deleting its first 256 candidates changes the next pass's prefix.The root issue is confusing a per-pass work bound with a progress guarantee. Keep the raw-entry bound and cross-process throttle, but make the bounded scan advance across successful no-op passes and process restarts. Persisting a cursor under the shared lease, rotating stable partitions, or an equivalent design is acceptable as long as directory mutation, cursor invalidation, and wraparound cannot permanently skip entries. Apply the same progress rule to both metadata and terminal-fact enumeration, while preserving targeted session-ID fast paths and all existing ownership, generation, inode, symlink, and malformed-data protections.
-
[P2] Assign the positive-retention age sweep to a recurring owner
src/utils/backgroundHousekeeping.ts:105
The current PR update says that the daily pass handles the full age-based sweep, butperiodic-retentionis called only fromcleanupOldMessageFilesInBackground().startBackgroundHousekeeping()invokes that function once behindneedsCleanupand never schedules it again. The minute path deliberately performs onlyperiodic-recoveryand returns without age cleanup whencleanupPeriodDaysis positive. The only 24-hour interval invokes npm-cache and old-version cleanup, and only forUSER_TYPE === 'ant'; it never invokes background retention.Consequently, a long-lived process can run its one startup sweep, complete a background session immediately afterward, and keep that session past its configured retention age for the remainder of the process lifetime. A later OpenClaude process may eventually clean it, but the claimed recurring daily owner does not exist. Wire the already-implemented
periodic-retentiontrigger into an actual recurring housekeeping owner that uses the existing 24-hour cross-process throttle. Keep the minute path limited to bounded prompt recovery and do not broaden this into minute-scale full scans or a redesign of transcript cleanup. -
[P3] Keep detached-child ownership until test-helper initialization completes
src/cli/bgFinalizer.test.ts:920
runWaitingDetachedLaunch()catches launcher-close and output-limit failures, but then parsesLogs:andPID:and awaits the readiness file outside that cleanup boundary. If a valid PID was emitted but the log-path assertion fails or readiness times out, the helper rejects before returningchildPid, so the caller never enters thetry/finallythat owns the detached child.runBuiltBackgroundProviderExit()has the same parsing gap. The child can remain alive and contaminate later tests or keep review/CI processes around. This is also the unresolved CodeRabbit request on the current head.Treat PID handoff as an ownership transfer: keep parsing, validation, and readiness inside a helper-level
try/finally, and relinquish cleanup only immediately before a successful return. On every earlier failure, terminate any valid detached PID and wait for it to stop, using the existing bounded graceful-stop/SIGKILLfallback where appropriate. Apply the same structure to both helpers so future initialization assertions cannot reopen this leak; production detached-process behavior should remain unchanged.
UpdateAddressed the latest retention-coordination feedback by preserving invalid policy state across the cleanup-worker handoff, making bounded recovery restart-safe, assigning positive-retention cleanup to a recurring owner, and hardening detached test-process cleanup. Addressed

I found three issues that still need to be addressed before this is ready.
Overall guidance
The first two findings are symptoms of the same coordination problem: the retention coordinator currently treats “the callback returned” as equivalent to “the pass completed successfully and its durable work may be acknowledged.” Those are not equivalent here. A callback can return normally after the in-lock policy check rejected the pass, and the reconciliation/cleanup helpers can return normally with retryable errors. The caller then publishes durable success state anyway—advancing or compacting the recovery journal and writing the throttle marker—even though some or all of the intended work did not complete.
Please address this as one pass-outcome and acknowledgement contract rather than adding unrelated conditionals at the two reported lines. The contract needs to distinguish at least these outcomes:
- the pass did not run because another process owns the throttle or the marker is fresh;
- the pass acquired responsibility but rejected the policy and performed no destructive work;
- the pass processed a bounded batch but some valid IDs need a later retry;
- the pass completed the work for which it took responsibility and may publish durable progress.
A policy-rejected pass must not be recorded as a successful throttle pass. A valid partial pass may still use the existing throttle to preserve resource bounds, but journal progress must acknowledge only work whose recovery responsibility was safely discharged. Retryable IDs must remain discoverable after a later process restart, while permanently malformed, stale, recent, or otherwise ineligible records must not pin the cursor forever. The implementation mechanism is open: a structured pass result, explicit acknowledgement/commit token, retry set, or equivalent design is fine if it enforces those outcomes.
Please add an end-to-end regression matrix around this shared contract, not only unit assertions for individual helpers. At minimum, cover valid and invalid policy before and after lock acquisition; a transient read, lock, or unlink failure followed by repair and a new process/pass; permanently retained or malformed entries before an eligible record; journal append during a full-sweep snapshot; and successful completion/no-op passes. Assert both the filesystem outcome and the durable coordination state: remaining journal IDs/cursor or snapshot contents, marker presence, and whether the corrected next pass runs. Keep the existing 256-record minute bound, cross-process locking, generation and inode revalidation, trusted-root and symlink checks, exact reservation ownership, fail-closed policy handling, and forward progress past permanently ineligible entries.
The exit-code finding has a separate, smaller root cause: the new wrapper normalizes an API input before Node converts it to the actual process outcome, but its normalization does not match Node's null/cleared-code semantics. Keep that fix at the process-outcome boundary and add focused coverage for process.exit(null) and process.exit() after process.exitCode = null; it does not require changing terminal-fact precedence or broader finalization behavior.
Findings
-
[P2] Preserve retryable journal work when a cleanup pass reports errors
src/utils/cleanup.ts:804
reconcileBackgroundSessionTerminalFacts()andcleanupBackgroundSessionsBefore()report ordinary I/O and lock failures through theirerrorsfields, but this path only logs those results and then unconditionally callsbatch.commit(). If a zero-day session is temporarily unreadable or an artifact unlink fails, its metadata/fact remains while the cursor consumes its only recovery record; the next minute pass has no ID to retry. The daily path likewise compacts its journal snapshot even when reconciliation or cleanup reports errors. This reproduces with a temporarily invalid names directory: after repairing it, the second recovery pass still leaves the metadata and the journal batch is empty. Preserve or re-enqueue retryable IDs, and avoid compacting failed daily work, while retaining the 256-record bound and forward progress past permanently malformed or ineligible entries. -
[P2] Do not throttle a daily pass that rejected the policy
src/utils/cleanup.ts:736
The locked retention callback represents a failed policy recheck by settingpassResult = 'invalid-policy'and returning normally, sorunWithBackgroundRetentionThrottle()still writes.retention-passas though cleanup completed. If settings or project MCP configuration becomes invalid between the pre-lock check and the in-lock recheck, then is corrected, the next pass is skipped for 24 hours and already-expired artifacts remain past their retention window. The current head reproducesinvalid-policy, creates the marker, and then returnsskippedimmediately after the configuration is repaired. Only stamp the throttle marker after a pass actually completed under a valid policy; apply the same outcome contract to the one-minute recovery marker. -
[P3] Preserve Node's cleared exit-code semantics in the new wrapper
src/cli/bgFinalizer.ts:543
The newprocess.exitwrapper evaluatescode ?? process.exitCodeand passes the result to a normalizer that mapsnullto 1. Node permitsprocess.exit(null)andprocess.exit()afterprocess.exitCode = nullto clear the code and exit successfully, so the base implementation'sexitlistener receives 0, while this wrapper records a failed terminal fact with exit code 1. This is also the current unresolved CodeRabbit request. Treatnulllikeundefinedon this new explicit-exit path while preserving the existing rejection of genuinely invalid exit codes.

In `@src/cli/bgFinalizer.test.ts`:
- Around line 1421-1431: Update the launcher output handling in this test to
reuse captureBoundedOutput for capped stdout/stderr collection and
waitForChildClose for the close wait, using the existing zero-retention launcher
context. Read the captured output only after assertWithinLimit(), while
preserving the existing release-file and child-kill cleanup in finally.
In `@src/cli/bgRegistry.cleanup.test.ts`:
- Around line 252-253: Guard the “unreadable” scenario in the test setup around
the fault handling branch so it is skipped or excluded when the effective user
ID is root, where chmod(directory, 0o000) cannot prevent readdir access.
Preserve the existing unreadable assertion for non-root environments.
In `@src/utils/cleanup.test.ts`:
- Around line 289-291: Update the JSON file count assertion in the cleanup test
to derive the expected length from the session count and
BACKGROUND_RECOVERY_ENTRY_LIMIT instead of hard-coding 44, preserving the
existing readdir filtering behavior.
- Around line 472-473: Make the terminalFailure setup in the cleanup test
deterministic by avoiding reliance on chmod(brokenPath, 0o555) to cause unlink
failure: either skip or gate the permission-based case for privileged POSIX
users, or inject the unlink failure directly. Preserve the assertion’s expected
partial cleanup behavior.
In `@src/utils/cleanupBackgroundSessions.fixture.ts`:
- Around line 365-367: Update the catch handler in the background cleanup
fixture to bind the caught error and write its message and stack along with the
existing failure context to stderr, preserving the exitCode assignment and
bounded-output behavior.
- Around line 123-125: Ensure the _recoveryBatchLimitForTesting configuration
fails immediately when OPENCLAUDE_CLEANUP_RECOVERY_LIMIT is unset or invalid,
instead of passing Number(undefined) as NaN and silently producing zero recovery
work. Validate the parsed value before invoking
takeBackgroundSessionRecoveryBatch while preserving valid safe-integer limits.
