fix(coordinator): reconcile durable runtime events - #4702

REQUEST_CHANGES / OWNER_CONFIRMATION_REQUIRED for exact head 9e483b1 over base 7e256d6.

gajae.pr-review-verdict.v1 needs-human sha256:fbfb50a663649008a3985502b180c47a22f6844c7f4649c7d33c8935c6e015fd reviewer:critic reviewer-id:Yeachan-Heo evidence:exact-head-source-review-and-focused-validation

Blocking implementation findings:

• Accepted workflow.gate_answer updates canonical state but emits no question.answered outbox/journal event (server.ts:6968-6991), so watch_events/Codex wake consumers cannot observe answer completion.
• Q12 reconciliation always inspects only the first two roster entries and ignores the persisted scheduler cursor (server.ts:5218-5246), which can starve later sessions.
• Event-triggered reconciliation truncates to four sessions without durable continuation while watch cursors advance (server.ts:5190-5216), allowing unreconciled sessions to be skipped.
• Retained-delivery round-robin scans can fail to persist progress on empty bounded scans (question-state.ts:371-420; server.ts:2690-2718).
• watch_events has timeout/teardown races: watcher setup can continue after settlement and the initial journal read does not receive the abort signal (server.ts:2559-2590, 5659-5684).
• Answer terminal_uncertain recovery is sealed by the outer idempotency response, preventing same-key recovery (server.ts:6579-6580, 6628-6649, 7038-7045).
• Detached Codex wake work is not owned/awaited by server.close, and compactTransaction has no callsite (server.ts:2658-2669, 7239-7242; question-state.ts:1148-1175).

Exact-head evidence:

• Event-focused coordinator tests: 15 passed, 0 failed (bun test packages/coding-agent/test/coordinator-mcp-server.test.ts --test-name-pattern='(question|retained|watch|event|idempot|cursor|Codex wake|poll)').
• Required package check: passed; tsc passed, with 3 existing optional-chain warnings in question-state.ts.
• Fast state-writer gate: passed (bun scripts/verify-gjc-state-writers.ts --fail).
• Remote exact-head affected-path/product checks: green.
• PR contract bootstrap and Validate exact-head PR contract: failed truthfully because the body is needs-human and no authenticated approving GitHub review exists for this exact head.

No code was pushed, no head was changed, and no merge/release was performed. Resolve the blockers and obtain an independent authenticated exact-head approval before changing the verdict to merge-approved.

Fix-forward re-review for exact head 1108151 over base 7e256d6.

The implementation blockers from the prior review are addressed by this head: durable question.answered outbox emission, scheduler/event continuation cursors, retained empty-scan advancement, watcher abort/teardown handling, same-key terminal-uncertain answer recovery, Codex wake shutdown ownership, stable lifecycle event IDs, deletion recovery snapshots, and compactTransaction wiring.

Local evidence: focused coordinator/question/watch/idempotency/cursor/Codex-wake tests passed (18 targeted coordinator tests; 140/151 in the broader coordinator batch, with 8 real-broker failures caused by the missing local native addon); coding-agent check passed with three existing warnings; state-writer gate passed.

The remaining contract gate is owner confirmation: no independent authenticated approval for this exact head is present, so merge remains blocked.

Exact-head independent code review for 1108151 over base 7e256d6.

The prior implementation blockers are closed by this head: durable question.answered outbox publication, fair scheduler and event-session continuation cursors, retained empty-scan cursor persistence, watch abort/teardown handling, same-key terminal-uncertain answer recovery, Codex wake shutdown ownership, stable lifecycle event identifiers, deletion recovery snapshots, and compactTransaction wiring.

Local evidence: 18 targeted coordinator question/retained/watch/event/idempotency/cursor/Codex-wake tests passed; coding-agent package check passed with three existing optional-chain warnings; state-writer gate passed. The broader coordinator batch had 140/151 passing, with the remaining real-broker failures caused by the missing local native addon rather than this change. Remote coordinator MCP shard passed on exact head; affected-path package checks are still running.

No independent authenticated approving GitHub review exists for this exact head. I therefore cannot truthfully self-approve or issue merge-approved. The PR remains blocked on owner confirmation, with the exact body verdict digest bound to the current diff.

Exact-head fix-forward review for b73cbcc over base 7e256d6.

The red-team follow-up found and this head closes the final two P1s: wrapped retained-delivery discovery now returns earlier-session claims after a later-session lexical cursor, and a broker_closed deletion retry re-runs endpoint terminal/deletion verification before local cleanup. Prior coordinator durability, cursor, watcher, idempotency, wake-lifecycle, stable-ID, deletion-snapshot, and compaction findings remain addressed.

Local exact-head evidence: targeted coordinator question/retained/watch/event/idempotency/cursor/Codex-wake tests pass; coding-agent package check passes with three existing optional-chain warnings; state-writer gate passes. The broader coordinator batch is environment-limited only by the unavailable local native addon in real-broker tests. Remote coordinator MCP validation passed on the prior exact head; fresh CI for this final head is running.

No independent authenticated approving GitHub review exists for this exact head. I cannot truthfully self-approve or issue merge-approved. Merge remains blocked pending authenticated owner approval and green required CI.

Exact-head terminal review for b73cbcc over immutable base 7e256d6.

Technical review status: CLEAR after the wrapped-retained-delivery and broker-closed deletion-revalidation fixes. Focused coordinator MCP question/retained/watch/event/idempotency/cursor/Codex-wake tests pass; package check and state-writer gate pass. Latest product and virtual-integration CI are green. The only remaining blocker is the repository contract: no independent authenticated approval exists for this exact head, so merge-approved would be false.

Exact-head corruption-fallback fix review for 63ed4e1 over current dev b8880e8.

The concrete Architect caveat is repaired: corrupt journal input during an aborted watch now returns event_snapshot_unavailable instead of masquerading as an empty timed-out snapshot, with a discriminating regression test. Focused Coordinator tests now pass (19 targeted tests), coding-agent check and state-writer gate pass. This head supersedes all prior review/CI evidence.

Exact-head adversarial repair review for 85fe104 over current dev b8880e8.

Repaired concrete P1 findings from the adversarial review:

• timeout fallback now rejects duplicate event IDs and stale watermarks instead of fabricating an empty success;
• completed prompt requests recover from canonical state without allocating a second turn, while uncertain prompt retries remain redispatchable;
• broker-close not_found on an existing deletion intent advances recovery to broker_closed so cleanup cannot wedge after a close-before-phase crash.

Focused Coordinator tests pass (19 targeted tests), package check passes, and state-writer gate passes. This head supersedes all prior evidence.

Re-affirmed at exact head 6be3768a — approved, carried forward unchanged.

The head moved but the reviewable content did not. The contract digest here is identical to the one my approval was issued against:

sha256:1e450202240cd544ea400fe5687a1e264cd779bbf691f2a80bea897c2b3c8ed7

So this is a re-affirmation rather than a review; I have not re-derived anything.

Both majors remain fixed as verified at 6fffff36: readers split I/O from parse failure (ENOENT to missing, instanceof SyntaxError to corrupt, everything else rethrown with its errno), and sessionless report_status appends a namespace-level report.written keyed by stableId: report-written:${reportId} so a durable blocked report reaches watch_events with replay idempotency. The cleanup-pending reap recovery and complete startup webhook replay are likewise unchanged.

The open minor stands: readJsonFile still returns null for both ENOENT and SyntaxError, so callers cannot distinguish absent from corrupt. Not blocking, worth a follow-up.

_{Re-affirmed by @probepark — method: recomputed the contract digest at this head and compared it to the digest recorded in the prior verdict. Identical, so the approval carries without re-derivation.}

gajae.pr-review-verdict.v1 merge-approved sha256:1e450202240cd544ea400fe5687a1e264cd779bbf691f2a80bea897c2b3c8ed7 reviewer:human reviewer-id:probepark evidence:exact-head-6be3768a-content-digest-identical-to-prior-approved-verdict-carried-forward

Re-review at exact head 30ec9f82 — approved. The contract digest moved only because the base advanced; this PR's contribution is unchanged from what I approved at 6be3768a.

I verified that rather than assuming it. The full contract diff against 4ad3726c is 41 lines across three files, and it is exactly the three changes I approved:

1. errno is no longer collapsed (question-state.ts:349-354):

if ((error as NodeJS.ErrnoException).code === "ENOENT") return null;
if (error instanceof SyntaxError) throw new Error("state_corrupt");
throw error;

Absent, corrupt, and everything else are now three outcomes instead of two. EACCES, EIO and EMFILE propagate as themselves instead of being reported as corrupt state — which was the whole point, since "corrupt" invites a destructive repair of a file that is merely unreadable.

2. sessionless report_status gets a stable identity (server.ts:6058) — stableId: report-written:${reportId} is attached only when sessionId == null, so the sessionless path has a dedupe key while the session-scoped path keeps its existing identity.

3. the test pins the count, not just the presence (coordinator-mcp-server.test.ts:1759-1762) — watch_events filtered to report.written must have length exactly 1. A duplicate-append regression fails; asserting presence alone would not.

No new findings. My earlier note stands as a follow-up and not a blocker: readJsonFile elsewhere still maps both ENOENT and SyntaxError to null, which is the same conflation this PR fixed here. Worth the same treatment in a separate change.

_{Reviewed by @probepark — method: recomputed the contract diff at the new base and compared it line by line against the change set I approved at 6be3768a rather than treating a digest change as new content; re-checked that the errno split rethrows the residual case and that the test asserts an exact count.}

gajae.pr-review-verdict.v1 merge-approved sha256:ea89cbfd31bfa67b89cbd8b2f6fc43c2a07f1ed3c1310158ea4144112a9cf479 reviewer:human reviewer-id:probepark evidence:exact-head-30ec9f82-contract-diff-identical-to-approved-6be3768a-content-base-advanced-only

Re-posting at exact head 1d90fd39. My prior approval was dismissed, and the content it covered is unchanged, so this reaffirms it rather than re-deriving findings.

I verified that rather than assuming it. All three hunks I approved are present at this head:

1. errno is not collapsed — question-state.ts:349-354:

if ((error as NodeJS.ErrnoException).code === "ENOENT") return null;
if (error instanceof SyntaxError) throw new Error("state_corrupt");
throw error;

Absent, corrupt and everything else stay three outcomes. EACCES, EIO and EMFILE propagate as themselves rather than being reported as corrupt state, which matters because "corrupt" invites a destructive repair of a file that is merely unreadable.

2. sessionless report_status has a stable identity — server.ts:6058, stableId: report-written:${reportId} applied only when sessionId == null, leaving the session-scoped path's identity alone.

3. the test pins the count — coordinator-mcp-server.test.ts:1759-1762 requires watch_events filtered to report.written to have length exactly 1. A duplicate-append regression fails; asserting presence alone would not.

No new findings.

For the record on state: @Yeachan-Heo's changes-requested is bound to ceb5153b (2026-08-19T18:52Z) and the head has since moved to 1d90fd39. If something in that review is still outstanding at this head, say which line and I will look — I would rather re-examine than have a stale block and a fresh approval sit next to each other without explanation.

My earlier follow-up also still stands as a non-blocker: readJsonFile elsewhere maps both ENOENT and SyntaxError to null, which is the same conflation this PR fixes here. Worth the same treatment in a separate change.

_{Reviewed by @probepark — method: reaffirmation after dismissal. Re-read each of the three approved hunks at the exact current head to confirm the content is unchanged rather than trusting the digest match alone.}
