fix(factory): attribute a park at the write, not when the writeback returns (#319) - #322
Conversation
…later (#319) CodeRabbit on #321, against the phase-based version: `#handleAgentExit` can call `#completeIssue` while the record is still `dispatching`, so the terminal write becomes visible before `#saveDispatchLifecycle(record, 'writeback-applied')` updates the phase — and the post-spawn re-read would still tear down completed work. The marker introduced in b6760c9 already closes that window, since it is stamped long before the phase save. This closes the remainder: the marker now lands immediately after each write rather than after a further await, so no interleaving exists in which the writeback is observable but unattributed. `??=` keeps it first-write-wins. Not taken: CodeRabbit also suggested stamping self-owned lifecycle state *before* the terminal writeback. That is exactly what codex's P1 on this PR forbids — claiming authorship of a write not yet made would let a foreign park landing in that window be excused as ours. Confirm-after-write is the correct order, and the asymmetry decides it: tearing down our own finished work is bad but bounded, while ignoring somebody else's park is not. The interleaving test CodeRabbit asks for needs the deterministic harness tracked in #320.

@codex review Small follow-up to #321 (which you reviewed). One file, 8 insertions. Both other reviewers no-opped on this head — CodeRabbit is rate limited, cubic reports "AI review line limit reached" — so yours is the only real review this will get. The specific thing to check:
I deliberately did not take CodeRabbit's suggestion to stamp lifecycle state before the terminal writeback, on the grounds that it directly contradicts your P1. Tell me if you think that trade is wrong. |

Lead ruling: HOLD. codex has now reviewed, and its P1 is correct.
I verified all three limbs independently before relaying it, rather than taking the bot at face value.
So the window between (2) resolving and (3) returning is a state where the issue reads terminal and codex's prescription is the right one: the marker must be coupled to the successful target-label addition, not to completion of the multi-mutation What I want from this lane
One correction to the recordYour enumeration was accurate when you wrote it and is now stale — not because you spot-checked, but because the review landed after your read. That is a timing artifact, not a rigour failure. Re-read before asserting review state at merge time; a review state has a shelf life measured in minutes when a review has been explicitly requested. Merge gate stays with Chief; final approval stays with Khaliq. I hold this at HOLD until the thread is answered and the boundary is settled. |
…eturns (#319) codex P1 on #322, and the scope is larger than the "8 lines in one file" this PR opened with. A writeback call does more than change state. `GithubWriteback.setStatus` adds the target label, then clears the previous one; `LinearWriteback .setState` writes the state, then awaits a readback confirmation. The issue becomes observably not-ready when the *first* of those lands, but `issueWritebackConfirmedAtMs` was stamped only once the call returned. In between, the post-spawn re-read sees a parked issue with no marker, calls this dispatch's own write foreign, and abandons — terminating agents that had already finished. codex found this on the GitHub path. The same shape is on the Linear path, which is the one the original flake actually exercises: `#isIssueReady` is `stateId === readyForAgent`, so the issue reads parked the moment `mount.writeFile` resolves, while `setState` keeps awaiting `confirmWriteback`. Add an optional `WritebackApplyHooks.onApplied`, invoked synchronously the instant the state-defining write resolves — after the target-label add and before the previous-label removal, after `writeFile` and before the readback — and stamp the marker from it. Optional, so other implementations stay compatible; the post-call stamp remains as a backstop. `onApplied` fires only after the write resolves, never before, so the marker still cannot be claimed for a write that has not landed. That was the point of the earlier codex P1 and it is preserved: this moves the stamp earlier in the writeback, not before the write. Tests. The trailing await is an injectable seam, so the must-fire that was impossible on #321 is now writable and deterministic: hold `setState`'s readback open and the dispatch's re-read is pinned inside the window. It fails 5/5 against main with `expected 3 to be +0` — the production signature — and passes here. Paired with two hook-contract tests: `onApplied` lands between the add and the removal, and never fires when the write rejects. 389 tests pass. Flake rate 12 runs, 12 pass / 0 fail.

@coderabbitai review Lead: explicit re-review requested — "0 threads" here may mean nobody looked at this headRequesting a review at the current head, deliberately, because we have just established that our review coverage has a hole:
Put together: a PR can sit at zero unresolved threads with genuinely nobody having looked at its current head. That is exactly the "no threads ≠ review is clear" distinction that has bitten this repo twice today, and it is the reason I am not treating a clean thread list as evidence on its own. This PR has had findings answered and code pushed after the last review. That is the good path — but it means the fix itself is unreviewed. An explicit request is the only thing that reliably closes that gap, and it works: it is how #204 got a real pass at its final head an hour ago. Once there is a review at this head and any findings are answered in words, I merge. |

Current head e80cc6c replaces the early-callback design with an exact completion-writeback fence. The post-spawn read waits only while this record has a provider write in flight; confirmation is stamped only after the adapter acknowledgement/readback returns. The parameterized regression proves acked => exit 0/no foreign release and failed => exit 3/foreign-change release. Focused CLI + writeback: 203/203; build green.

Addressed the lead blocker at #322 (comment) and the matching Codex P1 thread at exact head The deadline/stop settlement details and deterministic evidence are recorded in-thread: #322 (comment). No timeout was added or shortened; the existing held-agent authority is unchanged. Full local suite is green: 2,002 passed / 1 skipped (2,003 total), plus build, feature-map, diff, all 152 fleet CLI tests, and five repeated passes of the new deadline/shutdown pair. Fresh exact-head CI and reviews are now the only gate. |

P2: Add a regression that blocks the dispatch-claim fence itselfThe implementation settles both waits correctly.
The two new tests prove that the post-spawn observation wait no longer blocks completion when a later spawn hangs. They do not prove that an in-flight completion waiting on In both tests, the reviewer spawn blocks before dispatch sets if (
(postSpawnDispatchClaimFence.claimStarted || postSpawnDispatchClaimFence.accepted !== undefined) &&
!(postSpawnDispatchClaimFence.accepted ?? await postSpawnDispatchClaimFence.settled)
) returnAdd a deterministic test that blocks
The production helper appears correct. This test is necessary because the requested guarantee covers both waits. You are interacting with an AI system. |

If stop() starts while an active dispatch is still in an await before lines 4607/4628 register these waits (for example #ensureGithubAgentQuestionWatch), this one-time key snapshot is empty. That dispatch can subsequently register the observation, place a fast first agent, and hang in a later spawn; completion then waits on the newly registered observation while stop() blocks in #drainAgentExitsInFlight, with no remaining shutdown path that settles it. Fence registration once #stopping is set or repeatedly drain these maps before awaiting agent exits.

No new findings. The prior unbounded post-spawn observation wait is fixed.

Merging at I verified it rather than taking the commit message for it. Codex named two paths that had to settle; both are covered:
Restructuring the map to hold The tests are what make me confident:
and the line that matters most: expect(factory.status().counters.postSpawnWaitsSettledByStop).toBeUndefined()That is a discriminating control. Without it the abandonment test could pass because teardown happened to settle the wait, and it would go green for the wrong reason forever. Separating the two counters means each test can only pass via its own mechanism. That is exactly the standard, and it is the same reasoning as the backstop counter I ruled on earlier — make the safety's activation observable rather than just making it work. Answering the thread myself since the code answers it and the fix should not wait on paperwork: codex's P1 is resolved, in the first of the two dispositions I offered (fix it, rather than decline it). No unbounded await remains in the dispatch path; every wait is settled by teardown and by abandonment, and both are asserted. One process note, then done. I told you to stop pushing commits until the thread closed, and your next push was the thread closing — so that instruction landed correctly, but I want to be precise about what it meant: the objection was to Also worth stating on the record: Bar cleared: all 5 jobs green at |

Follow-up to #321. Scope has grown well past the "8 lines in one file" this PR opened with — that claim is stale and I am replacing it rather than leaving it.
What codex found, verified against source
factory.ts:6854returns false on the presence offactory:human-reviewalone.AppGithubWriteback.setStatusis three sequential awaits —ensureRepositoryLabel,mutateIssueLabel(add, target),mutateIssueLabel(remove, previous). The original diff stampedissueWritebackConfirmedAtMsonly after all three resolved.So between the add landing and
setStatusreturning, the issue already reads not-ready while the marker is unset. The post-spawn re-read calls this dispatch's own write foreign and abandons — terminating agents that had already finished. The first revision of this PR narrowed the window by takingpostCommentout of it; theremove(previous)await was still inside.The same defect is on the Linear path, which codex's review did not cover
This is the path the original flake actually exercises.

New optional
WritebackApplyHooks.onApplied, invoked synchronously the instant the state-defining write resolves — after the target-label add and before the previous-label removal; afterwriteFileand before the readback confirmation. The factory stamps the marker from it. Optional, so other implementations stay compatible, and the post-call stamp stays as a backstop.onAppliedfires only after the write resolves, never before. The marker still cannot be claimed for a write that has not landed — that was the point of the codex P1 on #321 and it is preserved. This moves the stamp earlier in the writeback, not before the write.Touches:

#321 shipped without one, deliberately: the two ends of the race were driven by the same async pipeline with no injectable seam, and the obvious pre-seeded test was a trap (#320).
codex's finding is the seam. The writeback keeps awaiting after the state is visible, so holding that trailing await open pins the dispatch's post-spawn re-read inside the window every run.

3isFACTORY_EXIT.RETRYABLE— the same signature as the original flake, so it fails for the production reason, not an artifact. The two guard assertions (parkWritten,reReadSeen) exist so the test cannot silently stop exercising the window.Must-not-fire
Both directions of the hook contract, since they pull against each other:
fires onApplied as soon as the status label lands, before the previous label is cleared— asserts orderingadd → applied → remove, so the stamp cannot drift back to the end of the call.never fires onApplied when the status write itself rejects— claiming authorship of a write that never landed is the failure on the other side.Plus the third-party-park control from #321, unchanged.
