fix(opencode): skip duplicate same-head review dispatch while in flight - #2283
seonghobae wants to merge 32 commits into
Conversation
Required OpenCode admission was re-posting repository_dispatch for an unchanged head after every fail-closed handshake, cancelling the queued central review (pg-erd-cloud#1183 4h queue / 9s fail). Dedupe on exact run-name before POST; still fail closed without a formal verdict. Co-authored-by: Cursor <cursoragent@cursor.com>

Exact-head review on 9535e7a38f3df8ce5a2d438b14484a39c2e4b6e9: the pagination/status/title false-negative repairs are useful, but the incident's cancellation invariant is not yet closed.
The new helper performs a classic check → POST sequence outside any atomic/serialized owner boundary. Two required admissions for the same {repo, PR, head} can both list central runs before either repository_dispatch has become observable, both receive missing, and both POST. The central workflow still uses PR-scoped concurrency ... cancel-in-progress: true, so the later same-head event can cancel the earlier one — exactly the failure class this PR claims to eliminate. GitHub Actions/API visibility is not an atomic compare-and-set, and the current tests only cover a pre-existing visible run; they do not exercise two simultaneous missing decisions.
There is a second identity gap: matching_inflight_runs() trusts only display_title from all central repository_dispatch runs. It does not bind the match to the canonical OpenCode dispatch workflow id/path. display_title is presentation/run-name data derived from dispatch payload; an unrelated repository_dispatch workflow with the same title shape could suppress a legitimate review. That remains fail-closed for approval, but it is an availability/queue-admission false positive.
RED:
- launch two admissions for the same exact head behind a barrier so both observe no existing run before either POST; assert at most one canonical dispatch becomes owner and neither same-head review is cancelled/restarted;
- feed an exact matching display title from a different central workflow id/path and prove it does not suppress the canonical dispatch;
- retain the current pagination, all-five-nonterminal-status, exact-title, malformed-identity cases.
GREEN needs one canonical idempotency/serialization authority around admission rather than a best-effort preflight alone. Reasonable implementations include a central owner claim/lease keyed by {repo,pr,head} with atomic create semantics, or another mechanism that makes same-head check+dispatch single-writer while still allowing a different head to supersede/cancel stale work. Whichever route is chosen, bind observed in-flight runs to the canonical opencode-review-dispatch.yml workflow identity as well as exact repo/PR/head. Preserve the formal receipt as the only success authority and keep the required job fail-closed.
Do not use an unchanged-head rerun/no-op commit as evidence. Reproduce the pg-erd-cloud#1183 class under concurrent admission, then reacquire exact-head hosted quality/security plus an independent non-author review. Duplicate-dispatch race / workflow-identity gate: FAIL.

Governance gate found during fresh OriginWeave prerequisite sweep: this Ready lane's repository+PR+exact-head workflow I am not treating AGENTS prose as proof that this PR is technically wrong: merged #1797 records the stale-generation native-cancellation race, this PR has executable RED→GREEN evidence for cross-head isolation, and #2289 adds live-revalidated predecessor cleanup. The problem is governance consistency. Canonical AGENTS lane #1885 now carries the reconciliation finding (comment 5747791655); it is itself 373 commits behind protected main and must non-destructively adopt intervening policy before changing the rule. Until that documentation/control-plane reconciliation lands, do not treat Ready, local GREEN, or hosted queue admission as merge authority for #2283. Preserve this PR and its valid deltas; no close, retarget shortcut, self-approval, force update, or gate weakening is requested. |

Current-head review after intervening source movement. I read the 91c19fd… -> 368b87cd… delta rather than treating it as a race: only scripts/ci/opencode_inflight_dispatch_gate.py and its focused contract changed. The gate now fails closed on malformed/id-less/title-less/unknown-status workflow-run rows and lists repository-dispatch runs once without per-status queries, eliminating a status-transition race that could collapse an existing in-flight owner to false missing. The current exact head is therefore 368b87cd929438241032bc6110e33856965b1f5a, not the stale body coordinate. Fresh hosted Runtime Quality, Python Security, Security Scan and SAST are queued and CodeQL is pending, so predecessor 91c19fd… success evidence does not transfer and this COMMENT is not merge acceptance.

Exact-head Runtime Quality RED 35500679987 is causal and reproducible, but the failing retained fixture is stale rather than the production admission gate. tests/test_opencode_required_verdict_regression.py::test_scheduler_wake_skips_dispatch_when_same_head_already_inflight fabricates a workflow-run row with only id + display_title; current production intentionally fails closed when status is missing/unknown. The test’s own contract says this is an exact-head queued central dispatch, so the minimal repair is fixture-only: add "status":"queued" to that fake row, keep production status validation unchanged, then require a fresh exact-head Runtime Quality GREEN. Do not rerun this head before source changes; do not weaken unknown/missing-status rejection.

Exact-head repair review for 928fc276891b185943a2a93ac003e227e4e47f6a:
- predecessor Runtime Quality RED
35500679987was traced to the retained fixture omitting the now-required workflow-runstatus; 0d472b4c546388e115fad9c1919696d7aeb3a098applies the minimal causal fixture repair only: the already-in-flight exact-head run is now explicitly"status":"queued"; production fail-closed status validation is unchanged;- the first whole-file write also removed the trailing newline unintentionally;
928fc276891b185943a2a93ac003e227e4e47f6aordinary-forward restores that formatting collateral. The combined semantic delta from368b87cd…is therefore the single queued-status fixture field only; - fresh exact-head hosted runs have materialized: Runtime Quality
35552210925, Security Scan35552210897, Python Security35552210893, SAST35552210972are queued and CodeQL PR35552210898is pending at review time.
This is source-repaired, not GREEN. Keep Draft; do not rerun predecessor failures or weaken the production gate. Acceptance requires fresh terminal exact-head Runtime Quality/security results and then normal stacked reconciliation of #2289.

35552210925, Security Scan35552210897, and SAST Semgrep35552210972are terminal success. Python Security35552210893is terminal failure delegated to canonical dependency owner #2278. CodeQL PR35552210898is terminal failure, but job/log RCA shows that failure is the workflow's fail-closed dispatch handshake rather than a source/SARIF finding.For CodeQL,
Detect CodeQL languages(106284151334) succeeded. The python/actions compatibility jobs (106399227168/106399227348) validated the live exact head/base, found no authenticated terminalcodeql-dispatch/*verdict, emittedverdict=pending, and intentionally failed with the contract message that the dispatch workflow would publish a terminal verdict and rerun those exact failed jobs. The coordinatorDispatch current-head CodeQL scan(106483754900) did not receive a runner until roughly 4h44m later; once admitted it successfully revalidated the live PR, bound both exact failed job IDs, obtained OIDC and a repository-scoped app token, and POSTed the exactcodeql-scanrepository_dispatch. The required run nevertheless remains red and the current head exposes no authenticated terminalcodeql-dispatch/actionsorcodeql-dispatch/pythonstatus yet.That lifecycle evidence is recorded on queue/admission owner #712 in comment
5769689179. Do not classify the CodeQL state as a.github#2283source defect, and do not blind-rerun either compatibility job before an authenticated terminal verdict exists: the workflow explicitly fails rerun attempts that lack such a verdict.The Python failure remains a shared dependency concern.
