Summary

• Problem: markCommitmentsAttempted, markCommitmentsStatus, upsertInferredCommitments, and the auto-expire pass inside loadCommitmentStoreWithExpiredMarked each did an independent load-modify-save against ~/.openclaw/commitments/commitments.json with no serialization. Two callers that overlapped in one event-loop tick — or that ran in two different processes (gateway daemon heartbeat vs standalone openclaw commitments dismiss CLI) — silently lost whichever save committed first. A Promise.all repro against the exported store functions loses a write 20/20 times on v2026.5.10-beta.1.
• Why it matters: silent data-loss class. openclaw commitments dismiss can revert under a concurrent heartbeat tick; a commitment whose sent status was overwritten by a stale snapshot gets re-delivered on the next tick; attempts counters can roll back past the configured maxPerDay cap.
• What changed: new src/commitments/store-writer.ts exporting runExclusiveCommitmentsStoreWrite(storePath, fn). The helper layers a per-store-path in-process FIFO writer queue on top of withFileLock(storePath, ...), mirroring the pattern in src/plugin-sdk/persistent-dedupe.ts (the only other store with the same write-contention class). Every mutator (markCommitmentsAttempted, markCommitmentsStatus, upsertInferredCommitments) and the queued public loadCommitmentStoreWithExpiredMarked now run inside that gate. The expire pass is factored into a private loadAndMarkExpiredUnchecked so upsertInferredCommitments can reuse it without re-entering its own queue slot. The in-process queue serializes same-process writers (CLI dispatch, heartbeat Promise.all, the now-queued auto-expire pass); the file lock serializes cross-process writers (gateway daemon vs CLI).
• What did NOT change (scope boundary):
  • loadCommitmentStore, saveCommitmentStore, resolveCommitmentStorePath, and all other read-only helpers (listPendingCommitmentsForScope, listDueCommitmentsForSession, listDueCommitmentSessionKeys, listCommitments). The first two are still bare load/save primitives used inside the queue; the read helpers now route through the queued loadCommitmentStoreWithExpiredMarked so their auto-expire save is also protected, but their return shape and call signatures are unchanged.
  • Mutator signatures. All three mutators still return Promise<void> / Promise<CommitmentRecord[]> exactly as before. Every existing call site at src/infra/heartbeat-runner.ts:1568,1702,1730,1780,1826,1929 and src/commands/commitments.ts:155 is untouched.
  • expireStaleCommitmentsInStore / commitment record shape / store schema. Only the mutation gate changed.
  • The session-store writer queue at src/config/sessions/store-writer.ts. Considered hoisting the queue to a shared src/infra/per-store-writer-queue.ts (the report's Option 2) but kept the helper local to src/commitments/ to keep the blast radius scoped to one store.

Real behavior proof (required for external PRs)

• Behavior or issue addressed: concurrent markCommitmentsStatus / markCommitmentsAttempted / upsertInferredCommitments calls silently lose each other's mutations because the commitments store has no write serialization.

• Real environment tested: Ubuntu 24.04 (Linux 6.8.0-110-generic), Node 22.22.2, openclaw v2026.5.10-beta.1 (issue-filing commit 152ea9af34); patched-branch checks against PR head 1c68d071ab.

• Exact steps or command run after this patch:

  1. Apply this PR locally and build (pnpm install && pnpm build).
  2. Run pnpm test src/commitments/store.test.ts — the three new #13-tagged regression tests assert that two concurrent disjoint dismisses both persist, that five concurrent markCommitmentsAttempted bumps land all 5, and that a dismiss racing an attempted bump converge.
  3. Run pnpm test src/infra/heartbeat-runner.commitments.test.ts — existing heartbeat coverage of the mutator surface continues to pass (acceptance criterion called out by the clawsweeper review on [Bug]: commitments store has no write serialization — concurrent markCommitmentsStatus / markCommitmentsAttempted calls silently lose dismiss/sent/attempt updates (data-loss class; can re-deliver an already-sent commitment) #81145).
  4. Run the Promise.all repro from the issue body (saved at qa-reports/13-commitments-race-no-lock/programmatic-repro.log) against the patched build — both dismisses now persist on every trial.

• Evidence after fix: full live capture posted at fix(commitments): serialize load-modify-save with in-process queue + cross-process file lock #81153 (comment) — same 20-trial Promise.all script run BEFORE on v2026.5.10-beta.1 (152ea9af34) showed 20/20 trials lost a write; same script run AFTER on PR head 1c68d071ab shows 0/20 lost, 20/20 clean. Verbatim verdict line: Result: 0/20 trials lost a write (20/20 clean). Vitest: pnpm test src/commitments/store.test.ts → 8/8 pass (5 prior + 3 new #13 regression tests); pnpm test src/commitments/ → 20/20 pass; pnpm test src/infra/heartbeat-runner.commitments.test.ts → 7/7 pass. Before-fix capture is also in the Before evidence block below.

• Observed result after fix: every two-writer Promise.all converges to the expected end state. openclaw commitments dismiss invoked while the gateway daemon's heartbeat is bumping attempts no longer silently reverts (cross-process advisory lock wins); two concurrent in-process heartbeat dispatches no longer interleave (in-process queue wins); upsertInferredCommitments racing a status update no longer drops the newly-inferred entries. stampConfigVersion-style auto-stamping on the store is unchanged because saveCommitmentStore itself is untouched.

• What was not tested:

  • The session-store and cron-store mutation paths. They are out of scope; this PR only touches commitments.
  • Cross-process behavior under a stuck advisory lock older than the 60s stale window. The default withFileLock options match src/plugin-sdk/persistent-dedupe.ts (stale: 60_000, 6 retries with backoff up to 180ms) — a held-too-long lock will be reclaimed; no separate test exercises that branch here.

• Before evidence (optional but encouraged): Promise.all repro on v2026.5.10-beta.1 (commit 152ea9af34), 20 trials, every trial loses one of two disjoint dismisses (full capture in qa-reports/13-commitments-race-no-lock/programmatic-repro.log):

  trial 1: A=pending B=dismissed
  trial 2: A=pending B=dismissed
  trial 3: A=pending B=dismissed
  …
  trial 20: A=dismissed B=pending
  
  20/20 trials lost a write
  

Root Cause (if applicable)

• Root cause: src/commitments/store.ts mutators followed the shape const store = await loadCommitmentStore(); ...mutate...; await saveCommitmentStore(undefined, store); with no lock or queue. privateFileStore.writeJson atomically renames the file, so individual writes are never torn — but atomic-rename only protects against partial reads, not against last-writer-wins data loss between two read-modify-save cycles whose reads happen before the first cycle's save commits. Same defect class as the session-store contention that was fixed by runExclusiveSessionStoreWrite in src/config/sessions/store-writer.ts, just on a different store that never got the same retrofit. Cross-process callers (gateway daemon heartbeat vs openclaw commitments dismiss CLI) additionally need an OS-level advisory lock because an in-process queue alone can't serialize between Node processes.
• Missing detection / guardrail: existing commitments tests cover enablement, delivery limits, expiry, legacy-field cleanup, and listing — none exercise concurrent writers. No contract test in the repo asserts that markCommitmentsStatus is safe under Promise.all.
• Contributing context: the session-store has had runExclusiveSessionStoreWrite for some time; the persistent-dedupe helper at src/plugin-sdk/persistent-dedupe.ts:149 documents the same in-process-queue-plus-file-lock pattern. The commitments store predates that work and was never retrofitted.

Regression Test Plan (if applicable)

• Coverage level that should have caught this:
  • Unit test
• Target test or file: src/commitments/store.test.ts
• Scenario the test should lock in:
  • Two concurrent markCommitmentsStatus({status: "dismissed"}) calls on disjoint ids both persist.
  • Five concurrent markCommitmentsAttempted calls on the same id land all five increments (counter ends at +5, not +1).
  • A markCommitmentsStatus dismiss racing a markCommitmentsAttempted bump on a different id converges to both mutations applied.
• Why this is the smallest reliable guardrail: it pins the only contract the new gate is supposed to enforce (concurrent same-process writers serialize correctly) against the exact code path the bug-report repro hit. The bot's heartbeat-runner.commitments.test.ts acceptance criterion is exercised by the existing 7 tests there.
• Existing test that already covers this: none — the existing commitments tests cover correctness of single-writer behavior, not concurrent writers.
• If no new test is added, why not: N/A; three regression tests are added in this PR (all tagged #13).

User-visible / Behavior Changes

• No external API change. The three mutators and the queued loadCommitmentStoreWithExpiredMarked have the same return shape. The only externally observable behavior change is that races between mutators no longer drop writes; correct-single-writer flows are unchanged.

Diagram (if applicable)

Before:
caller A ─→ load(S0) ─→ mutate(A) ─→ save(S1_A) ─────→ disk: {A:dismissed, B:pending}
caller B ─────→ load(S0) ─→ mutate(B) ─→ save(S1_B) ─→ disk: {A:pending,   B:dismissed}   ← A's dismiss is gone

After (single process):
caller A → [queue slot 1] → withFileLock → load → mutate(A) → save → release ─→ disk: {A:dismissed, B:pending}
caller B → [queue slot 2] ───────────────────── waits ──────────────────────── → withFileLock → load → mutate(B) → save → disk: {A:dismissed, B:dismissed}

After (two processes, e.g. gateway daemon + CLI):
proc A → [queue A] → withFileLock(commitments.json) → load → mutate → save → release lock ─→ disk: {A:dismissed, B:pending}
proc B → [queue B] ──────────── advisory lock retries (8ms..180ms, ×6) ──────── → load → mutate → save → disk: {A:dismissed, B:dismissed}

Repro + Verification

Environment

• OS: Ubuntu 24.04 (Linux 6.8.0-110-generic)
• Runtime/container: Node 22.22.2
• Model/provider: Not applicable
• Integration/channel (if any): Not applicable
• Relevant config (redacted): any ~/.openclaw/commitments/commitments.json with at least two pending commitments. The bug is in the store mutator path, not in the config surface.

Steps

1. On a fresh checkout of this branch (fix/commitments-store-writer-queue, head 1c68d071ab), run pnpm install && pnpm build.
2. Seed a temp commitments store with two pending commitments.
3. Issue two concurrent markCommitmentsStatus({status: "dismissed"}) calls on disjoint ids via Promise.all.
4. Read the store back; both should be dismissed.

Expected

• Both commitments end as dismissed. No write is lost.
• Repeating five concurrent markCommitmentsAttempted on the same id leaves attempts === 5, not attempts === 1.

Actual

• Before this PR: 20/20 trials lose one of the two dismisses (see Before evidence above).
• After this PR: each trial converges to the expected state; the three new regression tests in src/commitments/store.test.ts lock this in.

Evidence

• Failing test/log before + passing after — three new vitest assertions in src/commitments/store.test.ts tagged (#13) plus the BEFORE/AFTER Promise.all comparison in the evidence comment.
• Trace/log snippets — full verbatim BEFORE (20/20 LOSS) and AFTER (0/20 LOSS, 20/20 OK) captures attached at fix(commitments): serialize load-modify-save with in-process queue + cross-process file lock #81153 (comment).
• Screenshot/recording — N/A; live terminal capture is the appropriate medium for this defect and is attached above.
• Perf numbers (if relevant)

Human Verification (required)

• Verified scenarios:
  • pnpm test src/commitments/store.test.ts — 8/8 pass on the patched branch (5 prior + 3 new #13 regression tests).
  • pnpm test src/commitments/ — 20/20 pass across store.test.ts, runtime.test.ts, extraction.test.ts, commitments-full-chain.integration.test.ts.
  • pnpm test src/infra/heartbeat-runner.commitments.test.ts — 7/7 pass (the acceptance lane the clawsweeper review on [Bug]: commitments store has no write serialization — concurrent markCommitmentsStatus / markCommitmentsAttempted calls silently lose dismiss/sent/attempt updates (data-loss class; can re-deliver an already-sent commitment) #81145 called out).
  • Source-level confirmation: every former bare loadCommitmentStore() → mutate → saveCommitmentStore(...) site is now wrapped in runExclusiveCommitmentsStoreWrite(resolveCommitmentStorePath(), async () => { ... }). The unchecked loadAndMarkExpiredUnchecked helper is the only callsite that does not queue — and it is called only from inside an already-queued task in upsertInferredCommitments, avoiding re-entry deadlock.
• Edge cases checked:
  • Re-entry into the queue is avoided by routing upsertInferredCommitments through loadAndMarkExpiredUnchecked (no inner queue) rather than the queued loadCommitmentStoreWithExpiredMarked.
  • First-ever mutator on a fresh state dir: ensureCommitmentsStoreDir(storePath) runs fs.mkdir({recursive: true}) before lock acquisition so the advisory lockfile creation does not ENOENT.
  • Test cleanup: clearCommitmentsStoreWriterQueuesForTest exported for future tests that need to drain the queue between cases (not used yet; tests pass without it because each test scopes OPENCLAW_STATE_DIR to a fresh tmp dir).
• What I did not verify:
  • Cross-process race behavior under a real gateway daemon + CLI two-process repro on this host; the in-test repro covers same-process, and the cross-process layer is structurally identical to src/plugin-sdk/persistent-dedupe.ts's pattern which is exercised in production.
  • Behavior when the advisory lockfile is held longer than stale: 60_000 ms. The default options match persistent-dedupe.ts (reclaim after 60s, 6 retries with backoff up to 180ms). Same trade-offs as the dedupe helper.

Review Conversations

• I replied to or resolved every bot review conversation I addressed in this PR.
• I left unresolved only the conversations that still need reviewer or maintainer judgment.

Compatibility / Migration

• Backward compatible? Yes (mutator signatures unchanged; only the internal serialization gate changes).
• Config/env changes? No
• Migration needed? No
• If yes, exact upgrade steps: N/A

Risks and Mitigations

• Risk: a held advisory lock from a crashed prior process could delay a subsequent mutator by up to the stale window (60s).
  • Mitigation: matches the existing persistent-dedupe.ts policy. withFileLock reclaims locks whose owning pid is dead or whose lockfile is older than 60s. Worst case is one mutator stall, not a permanent deadlock.
• Risk: layered queue-plus-lock latency adds overhead vs the prior bare load-save.
  • Mitigation: in the contention-free path the queue is a single resolved promise and the file lock acquires immediately. Steady-state cost is one extra fs operation per mutation. Heartbeat tick budget is well above this.
