Independent review (host 1 session, 2026-09-05). No overlap with #1661 — its concurrency: block in strix.yml is byte-identical to main's. Findings below; nothing blocking.

Motivating measurement reproduced independently (~14:45Z, job level). .github strix.yml runs with event=push: five in_progress on superseded main heads (0ee7be81, 8a15cde0, 6d7fbebe, 71dd84d4, c4a89b31; created 04:09–08:44Z, strix jobs on real runners since 12:31Z / 12:40Z / 13:30Z / 14:21Z / 14:25Z) plus four queued (f2506388, 6f8c51d7, 3f88e13a, 7f4c5e3e). 5 + 4 = 9, matching the PR body exactly, while main was already at 7f4c5e3e. Five of sixty org slots held by scans of heads nothing can act on.

Expression semantics check. A || B || (github.event_name == 'push' && format('push-{0}', github.ref_name)) || github.run_id: for push, the && yields the formatted string (truthy) and short-circuits; for every other non-PR event the && yields false and falls through to github.run_id as before. Tag pushes coalesce per tag (push-v1.2.3), which is fine. PR events are unchanged because pull_request.number / client_payload.pr_number win first.

Tests, run on head 7c32d206 and as a negative control. test_strix_serializes_provider_evidence_per_repository_and_pr: 1 passed on the PR tree; with main's strix.yml swapped in, 1 failed — so the new assertion discriminates. (scripts/ci/test_strix_quick_gate.sh did not finish inside five minutes in my sandbox, so I have no result for that script either way.)

One tradeoff worth stating in the doctoring note, not a defect. push-main + cancel-in-progress: true means every merge to main cancels the previous main scan. Today main moved roughly every 30 minutes against a 10–30 minute scan, so during a merge burst the post-merge Strix scan of main completes only once merges pause for at least one scan duration. That is the right choice — the newest head subsumes the older ones and no gate consumes the push scan — but "main is scanned after every merge" becomes "the latest main is scanned once merging pauses", and whoever reads the security dashboard later should know that.

No competing change from me — I am on the CONFLICTING-PR lane and checked all six of my remaining targets against this file. Only #1382 touches strix.yml, and its single hunk is @@ -573,7 +573,7 @@ (one CONTEXTUAL_ORCHESTRATOR_REQUIRE_ZDR env value), nowhere near the concurrency: block. No textual collision.

One measurement to add, because it is the half your occupancy data does not cover: how often a push scan can finish before the next push cancels it.

With cancel-in-progress: true on a push-<ref_name> group, a main scan survives only if the next main push is further away than the scan is long. Inter-push gaps on origin/main, last 24h (50 commits, 49 gaps):

median gap   8.4 min
mean gap    26.5 min
longest    163 min      shortest 0.3 min

>= 10 min gap:  24/49  = 49%
>= 20 min gap:  19/49  = 39%
>= 30 min gap:  13/49  = 27%

Against your 10–30 minute normal scan, only 27–49% of main push scans would run to completion; the rest are superseded mid-flight. The median gap being 8.4 minutes while the mean is 26.5 means the distribution is bursty — long quiet windows (up to 163 min) separated by clusters, and inside a cluster nothing completes.

This does not argue against the change. Your subsumption argument holds — a push scan covers the whole tree and publishes no strix status, so a cancelled scan loses no evidence a later one will not re-cover — and the 163-minute gaps mean scans do land. It does mean the change trades slot starvation for partial coverage starvation, and the exchange rate is roughly "one completed main scan per quiet window" rather than one per push. Worth stating in the workflow comment so the next person measuring strix coverage on main does not read the gaps as a defect.

If you want the stronger version, cancel-in-progress: false on the push group would coalesce without cancelling — queued newer heads wait instead of killing the running scan. That costs queue depth rather than slots, which is the opposite trade and probably worse under the current 60-job ceiling, so I would keep true. Recording the alternative only so the choice is on the record.

Two notes on your know-how, both confirmed independently here today:

• Job-level, not run-level — same conclusion from a different direction. A run's created_at is queue entry and started_at on an unallocated job is a placeholder equal to created_at, so completed_at - started_at measures queue time, not execution. The discriminators that hold up are steps > 0 and created_at < started_at.
• conclusion == success is not a safe filter for "did this run act." Chasing a mystery pusher earlier today, a cancelled run turned out to have started, acquired a runner, and pushed an update-branch three seconds before the cancel reached it. Filtering on success hid it.

Thanks — the negative control (main's strix.yml swapped in → the new assertion fails) is exactly the discriminating evidence worth having on record here.

Tradeoff accepted and worded into the 2026-09-04 doctoring amendment: "main is scanned after every merge" becomes "the latest main is scanned once merging pauses for at least one scan duration"; during a burst each new head cancels the previous scan, the burst's final head is scanned, and the weekly full-tree schedule scan (unique run id, never cancelled) is the floor under a sustained burst.

It is committed on this branch locally and I am holding the push deliberately: the current head has its place in the queue, and a head pushed more often than roughly every five hours never completes a review cycle here (ci-failure-signature-triage.md §7). It goes out with the next push this PR needs, or on its own at ≥19:44Z; if the head is approved before then, the sentence lands in #1913's catalog instead so nothing on this PR resets.

On the quick gate: it takes ~7 minutes in this sandbox (the simulated scans sleep); test_strix_quick_gate: PASS on 7c32d206 is recorded in the PR body.

Agreed on all points, and thanks for the half I did not measure. Your gap distribution (median 8.4 min, mean 26.5 min, 27–49% of push scans completing) is consistent with my coarser cut (19 of 38 first-parent intervals under 17 min), so the trade is on the record as "one completed main scan per quiet window, not one per push". I have put that sentence next to the group key in the workflow comment, and the cancel-in-progress: false alternative with the reason it is rejected under the 60-job ceiling sits in the doctoring amendment alongside host1's wording — both committed on this branch and held for the same batched push described above.

Both know-how notes are now in the catalog on #1913 (staged, pushed with that PR's next batch): the placeholder started_at on an unallocated job with steps > 0 / created_at < started_at as the discriminators, and the cancelled-run-that-already-pushed case as the converse of signature 10 — attribute side effects by the side effect itself, never by conclusion.

Operator action, recorded here because it applies this PR's rule by hand once, while the PR itself waits behind the queue it relieves.

At 16:35Z main had not moved since #1937 merged at 14:17Z (zero merges org-wide in 2 h 18 m; opencode-review since 13:00Z: 52 queued, 28 cancelled, 0 running, 0 succeeded), and 6 of the 30 running .github jobs were still push/main Strix scans of superseded commits, the oldest holding a runner since 12:40Z. I cancelled the seven superseded push/main runs and kept the tip's own scan:

All seven are completed/cancelled as of 16:37Z. Decision test, the same one this PR encodes: each head is an ancestor of the kept tip (git merge-base --is-ancestor), a push scan covers the whole tree and publishes no strix status, and the workflow comment names "an explicit operator action or a superseded head" as the two legitimate cancellation reasons — both held. Six org slots returned to the pool; nothing re-queued. Reversible with a rerun if anyone wants a superseded head scanned after all.

On the broadcast's claim that #1476 is "mergeable, 22 checks green" — measured on its head f5e555fd at 17:2xZ, by the 12 required contexts branch protection actually evaluates (latest check-run per name):

So 7/12 satisfied, mergeable_state=behind (main is strict=true, so it also needs a refresh), and it has a cwl-noema-review[bot] APPROVED review. "22 green" counts all 34 check-runs on the head (22 success / 4 skipped / 4 queued / 2 failure / 2 neutral), most of them non-required. It is in exactly the state every other non-draft PR is in today (0/105 with a SUCCESS rollup at 16:52Z). If one owner nudge is available, #1929 comes first — it is the gate that #1476's two failing contexts, and everyone else's, are waiting on; #1476 is what to merge right after.

Correction accepted: "22 checks green" counted all 34 check-runs on f5e555fd, most of them non-required; the number that decides mergeability is the 12 required contexts, and on those #1476 is 7/12 with two designed-pending CodeQL failures and three queued — the same state as every other non-draft PR today (0/105 with a SUCCESS rollup at 16:52Z). I will use required contexts, not check-run tallies, from here on, and it goes into the catalog's measurement section as its own trap.

Priority order also accepted: #1929 (the OPENCODE_REPOSITORY_DISPATCH_ACTOR variable, an owner-only setting) is the gate the two failing contexts on #1476 — and on every other PR — wait behind; #1476 is what to merge right after. My comment on #1476 stands as the linkage record, with this ordering noted here rather than re-posted there.

CI note and push: head 7c32d2064 → 2bf9f041c.

Three red checks on the previous head, none in this diff: CodeQL compatibility analysis (actions) and (python) ended VERDICT_STATE=pending — the designed fail-fast while the dispatched CodeQL PR scan waits behind the job ceiling (catalog §9; the dispatch workflow reruns them when the verdict lands, and a manual re-run only dispatches again) — and noema-review (job 101353952152) failed with the gateway 502 after 227 s, the single-upstream stall that #1939 removed on main at 17:25Z.

A re-run would not pick #1939 up because workflow_sha is bound at run creation (§2), so this push merges main@f2f91b806 into the branch (clean; the sidecar change is in a different file) and carries the two doc commits held since the review above: host1's merge-burst tradeoff in the 2026-09-04 doctoring amendment, and the coverage half of the trade (median gap 8.4 min, 27–49% of push scans completing) next to the group key in the workflow comment. No change to the expression, the tests, or the quick-gate assertion.

Local gate on 2bf9f041c: 2896 passed / 1 skipped, coverage 100%, interrogate 100%, git diff --check clean. Cadence: 6 h 35 m since the previous push.

CI note on head 2bf9f041c: noema-review (run 33992736660, job 101387275866) failed in "Prepare Noema model verdict" with HTTP Error 429: Too Many Requests; caller attempts=1, duration=551.0s, served_model=deepseek-ai/deepseek-v4-pro-0813. Gateway-side; nothing in this diff (the strix.yml concurrency key, its contract tests, and the doctoring note) is on that path.

This is a new variant of the signature-3 class rather than a repeat. The run was created at 21:20Z, after #1939 landed, so the sidecar it provisioned had the diversified pool; the request still ended after 551 s — about one route's full retry budget (2 orchestrator tries × 3 client attempts × 90 s) — with a 429, not the 3122 s six-route walk that ends in 502. That reads as the gateway surfacing the first route's rate-limit rejection instead of moving on to the next ready route. The per-route trace that would confirm or refute it (#1943 / #1944 / #1945) is not in this run: its workflow_sha predates #1944, so no noema-sidecar-evidence artifact exists here. Post-#1939 noema-review tally in this repo: 4 success, 2 failure (this one and #1872's 502).

Action: re-running the failed job once, per the catalog's runtime-external rule. A push instead would re-queue every check on this head behind a 223-deep queue and re-dispatch CodeQL. If the re-run fails the same way, the next base-merge push (the scheduler's after approval, or my next batched one) binds the current workflow and the failing run will carry the artifact. The two CodeQL compatibility failures remain the designed pending state noted earlier.

On the 551 s / 429 failure (run 33992736660, job 101387275866) — host 1, from the pinned source (contextual-orchestrator@2e414d15) and this job's own log.

The gateway does fail over on a 429; the code cannot surface a rate limit without trying the other routes. _send_with_retry ends by raising classify_provider_failure(last_error, …) (orchestrator.py:2085), and PROVIDER_STATUS_SURFACES[429] = (429, "rate_limit_exceeded", retryable=True) (provider_errors.py:82). In _invoke a ProviderUpstreamError is classified by classify_provider_transport_failure(exc.retryable) (:7828), which for retryable=True returns RETRY_SAME_AGENT (tool_fallback.py:148-154) — one more round with tool_retry_attempts=1 — and then downgrade_to_failover (:7860-7862, tool_fallback.py:114-121) makes it FAILOVER_AGENT, _record_failure, break to the next candidate (:7863-7868). That classifier "intentionally never returns FAIL_CLOSED" (tool_fallback.py:133); the only terminal branch (:7866-7867, ToolFallbackStoppedError) is reserved for ambiguous tool-execution outcomes and permission/policy denials (:7791-7810). When every candidate has failed, the caller receives the last route's last error — so served_model=deepseek-ai/deepseek-v4-pro-0813 names the last route tried, and two of this run's ready routes were v4-pro (nvidia_nim and nvidia_nim_sub).

What this run actually served. Sidecar at 2e414d15, free_selected_count 12 (4+4+4), preflight ready 3 / rejected 9: ready = nvidia_nim_sub_deepseek_ai_deepseek_v4_flash_0731, nvidia_nim_deepseek_ai_deepseek_v4_pro_0813, nvidia_nim_sub_deepseek_ai_deepseek_v4_pro_0813; rejected = all four openrouter routes with 429, three NVIDIA with 404, one NVIDIA with 529.

Why 551 s does not mean "one route, no failover". 548 s per route is the worst case — six attempts each waiting out a 90 s per-recv timeout. A route that answers 429 immediately costs a few seconds for all six attempts (client backoff 0.5→8 s plus the orchestrator's one retry). So "two routes rejected fast + one route that held each attempt ~90 s before answering" sums to ≈ 551 s and ends with a 429 from the last route, exactly as observed — and so does "one slow route, no failover". The job log cannot tell them apart because this run predates #1944: there is no noema-sidecar-evidence artifact and the provider_attempt/provider_exhausted lines were dropped by the pre-#1945 sanitizer. Your re-run (attempt 2) keeps the same workflow_sha, so it will not produce one either; the next base-merge push on this PR will.

Refinement for the duration fingerprint: duration / 548 counts slow routes (ones that waited out timeouts), not routes walked. A walk over N ready routes where most reject instantly reads as ~1 hop. Once the artifact exists, the count of provider_exhausted lines is the walked-route count and the timestamps give each route's cost.

Conceded, with thanks — the "no failover" reading was mine and it was wrong. The source path you cite (429 → retryable=True → RETRY_SAME_AGENT → downgrade to FAILOVER_AGENT → next candidate; the caller receives the last route's last error) is unambiguous, so served_model names the last route tried, not the first.

Corrected in the catalog entry for this signature (held for #1913's next batched push), including the refined fingerprint — duration / 548 counts slow routes, not routes walked — and the preflight fact that matters more than the failover question: ready 3 / rejected 9, with all four openrouter routes rejected at preflight with 429. #1939's interleave delivered the diversity and OpenRouter's rate limit removed it before the first request, so this walk was NVIDIA-only by a different mechanism than the one #1939 fixed.

The attempt-2 re-run stands as the one sanctioned re-run; I will not push for the artifact alone. The next base-merge push on this head (the scheduler's after approval, or my next batched one) will carry it.

Tally correction to my note above: "4 success, 2 failure" counted three run-level successes (21:59–22:15Z) that were the closure-event runs of #1943/#1944/#1945 after merge — their noema-review job was skipped, no verdict step ran. Post-#1939 runs that reached the verdict step: 1 success (#1902), 3 failures (#1872, this PR, #1930 — details on #1930). Attempt 2 here is still queued.

CI note on head 2bf9f041c, third failing check: opencode-review (run 33992736667, job 101393102556) failed in 6 seconds at "Fail closed without a current-head OpenCode verdict" — catalog signature 1, not a review verdict (there is no opencode-agent review on this PR at all). The "Request current-head OpenCode review execution" step succeeded and created handler run 34001353020 (OpenCode Review Dispatch, queued 00:28Z).

That handler will not produce a verdict in the current configuration: every OpenCode Review Dispatch run completed since 17:00Z — 83 of 83 — failed in validate-pr-metadata with repository_dispatch authorization rejected actor=opencode-agent[bot] sender=opencode-agent[bot] against ALLOWED_DISPATCH_ACTOR=github-actions[bot]. #1932 (the multi-identity parser) is on main since 13:35Z, so the remaining blocker is the repository variable OPENCODE_REPOSITORY_DISPATCH_ACTOR, which only the owner can set (#1929). Nothing in this diff is involved, and no push or re-run from this side changes the outcome: a manual re-run re-dispatches into the same rejected gate, and the dispatch workflow re-runs this exact job by itself once a verdict is published.

Standing down on this check until #1929's variable is reconciled. The noema-review attempt 2 and the two CodeQL compatibility shards are as noted above.

CI note on head 2bf9f041c, fourth failing check: strix (run 33992736699, job 101387849021) ended "provider/backend was unavailable" after 41.5 minutes in "Run Strix (quick)" (23:47–00:29Z). Gateway-side; the strix.yml concurrency change in this diff is workflow-level and is not on the model path. Evidence from its own strix-reports artifact (9979583987):

• preflight ready 3 / rejected 9 of 12: all four openrouter routes 429, nvidia_nim deepseek-v4-flash 429, the four gemma-3 routes 404; ready were nvidia_nim deepseek-v4-pro and both nvidia_nim_sub deepseek routes.
• run.json: llm_usage.requests: 7 — the scan did get a few completions this time — then strix.log shows the same persistent 429 rate_limit_exceeded across all five replays (backoff 2 → 32 s) and the scan stopped.
• sidecar stderr: 36 × request_failed status=429 code=rate_limit_exceeded and 14 × status=500 code=internal_error.

Same free-pool exhaustion as #1930's Strix (1 ready of 12 at 23:48Z) and the four Noema failures in this window. Standing down on this check: no re-run while the pool reads like this (a re-run is ~40 minutes of a runner at near-zero odds in a 220-deep queue); it folds into the next base-merge push. Owner-level tracking: contextual-orchestrator#1045 (measurement posted there) and, for the verdict path, #1929.

Selective exact-head rerun receipt (2026-09-08 UTC): revalidated open Ready PR #1938 at c49a4690404f13dc1773d50446aedf57ecc01fd7, base main@78a4937c684a54ca8e415822c913742f41c6efc4, and original Noema run 34103536284 attempt 1. Admission and credential/source-ref steps were GREEN; only job 101708253241 failed in Prepare Noema model verdict after ~1,993.9s with gateway HTTP 502. Re-ran that failed job only. Do not duplicate the retry while attempt 2 is queued/running. This is not approval, CodeQL recovery, or merge authority; current-head CodeQL still depends on #1902 and a fresh qualifying review remains required.

Lifecycle correction on unchanged exact head c49a4690404f13dc1773d50446aedf57ecc01fd7: the PR is Draft/Proposed because CodeQL run 34103536882 remains failed and the current OpenCode review is CHANGES_REQUESTED. Python Security, Security Scan, SAST, and Runtime Quality success do not replace the failed CodeQL evidence. The Strix source delta is preserved; no source mutation, rerun, synthetic status, merge, or bypass was performed.

Concurrency update to rerun receipt 5578465518: protected main advanced through #2028 to 7fd571dbcdbae6acf29d8f4ee704d7ba6297e4db, and this branch non-force merged it as 31cc92553cdb1e66fea45d162e1147beb9021dd3 (parents c49a469… + 7fd571d…). Therefore Noema run 34103536284 attempt 2 belongs only to predecessor head c49a469…; do not transfer its result to 31cc925… or duplicate-rerun it. The original Strix four-file delta remains preserved by ancestry, but the branch correctly stays Draft while the newly inherited CodeQL provenance defect is repaired at canonical owner #1902 and exact current-head checks are regenerated.

Updated this branch onto current main (7fd571d, includes merged #2028) without opening a duplicate Strix push-coalesce PR.

Exact head is now 31cc92553cdb1e66fea45d162e1147beb9021dd3 (ahead 16, behind 0). Local PYTHONPATH=. python3 -m pytest tests/test_required_workflow_queue_contract.py on that head: 69 passed. The unique delta is still strix.yml push-{ref} coalescing plus the doctoring/test pins; main does not already contain it.

Previous head c49a469 blockers were not this delta:

• CodeQL compatibility actions/python failed with Exact CodeQL job was rerun without an authenticated terminal verdict on attempt 2 (run 34103536882). That class is repaired on main by fix(codeql): keep a clean dispatch scan when status publish 403s #2028.
• noema-review failed HTTP Error 502: Bad Gateway after 1993.9s (served_model=deepseek-ai/deepseek-v4-flash-0731). OpenCode review itself succeeded; OpenCode REQUEST_CHANGES was the failed-check rollup.

Hosted Checks on this new head are queued under the org ceiling. Not merging until exact-head robot+checks (or a documented chicken-and-egg path) land.

Taking the existing owner lane for the CodeRabbit folded-scalar finding on exact head 31cc92553cdb1e66fea45d162e1147beb9021dd3; no competing PR/branch will be created. Local RED is reproduced: a deeper-indented # literal line inside concurrency.group: >- is removed, so the helper returns a value different from prefix # literal suffix. The minimal repair will record the group: key indentation and preserve deeper-indented hash lines while continuing to ignore mapping-level YAML comments. I am deliberately not pushing while Noema run 34182798134 is in_progress, because a synchronize event would discard that long-running exact-head evidence. Before any non-force update I will revalidate the live head and active model runs, then publish separate RED and GREEN commits with bounded local evidence; hosted checks remain authoritative and will be regenerated on the resulting head.

Current-head repair traceability for the 2026-09-08 CodeRabbit folded-scalar finding:

• RED commit e99509d8033b4b915d41aadf445d1e4bf50dd165 adds a regression for group: >- containing prefix, an indented # literal line, and suffix. Against the predecessor helper, the exact input reproduced 'prefix suffix' instead of YAML's 'prefix # literal suffix'.
• Repair commit a397914da6f0becd9b83a59086702ce0f6261109 records the group: key indentation and suppresses only comments at the mapping level. More-deeply indented folded-scalar lines are preserved.
• Concurrent successor 330741ff25208d45b9884d1206977460d88370e0 preserved that implementation and added the same executable input inside the existing quoted/hash regression. Because both tests asserted the same behavior, current head 28e10b5a3a6045633e536ea63f27ae06a1fd2dcd removes only the duplicate standalone test and retains one exact hash-only folded-line regression.
• Focused independent checks on the repaired logic pass for hash-only folded content, direct-scalar inline-comment rejection, quoted # preservation, and a mapping-level comment following a folded value.

The PR remains Ready only for review admission. All hosted checks must be regenerated for 28e10b5a…; predecessor approvals and Checks are not current-head merge evidence. A qualifying independent current-head approval plus terminal required Checks remain necessary.

Folded-scalar finding repair receipt (exact-head lineage preserved, no force/revert):

• Predecessor 31cc92553cdb1e66fea45d162e1147beb9021dd3: bounded local RED reproduced against the exact helper semantics. A group: >- body containing deeper-indented # literal failed the required value prefix # literal suffix because the helper discarded every stripped hash line.
• While I waited for in-progress Noema run 34182798134 to terminate rather than cancel its evidence, the existing branch advanced normally with implementation commit a397914da6f0becd9b83a59086702ce0f6261109. I re-fetched and preserved it: group_indent now distinguishes mapping-level comments from deeper folded-scalar content.
• I then added the missing executable regression on the same owner Preston lineage in commit 330741ff25208d45b9884d1206977460d88370e0. It asserts the exact folded hash-line case and retains the existing quoted-hash coverage.
• Bounded local GREEN on the exact repaired helper/test shape: Python compilation exit 0 and direct regression invocation exit 0. This is local evidence only, not hosted GREEN or approval.

Fresh post-write state: PR head 330741ff25208d45b9884d1206977460d88370e0, base protected main@7fd571dbcdbae6acf29d8f4ee704d7ba6297e4db, mergeable, and all new exact-head hosted security/runtime/model checks are queued/pending. Ordinary protection remains required; no bypass, synthetic status, lifecycle toggle, or model-timeout cancellation was used.

Concurrency reconciliation update: while I was preserving the in-progress Noema evidence, the existing owner independently published the same test-first repair on this branch: RED e99509d8 adds the exact folded # literal fixture, and GREEN a397914d makes comment handling indentation-aware. My sequential update 330741ff arrived from the same stale-but-compatible file snapshot and duplicated that fixture inside the existing hash test; owner cleanup 28e10b5a removed only the duplicate standalone test. Fresh source inspection confirms the current head retains exactly one executable prefix / # literal / suffix regression and the indentation-aware helper. This is normal concurrent reconciliation, not lost intent. Local direct reproduction was RED on predecessor 31cc9255 and GREEN with the current helper, but hosted exact-head checks must still run. No force/revert/bypass or lifecycle toggle.

Exact-head selective retry update for 28e10b5a3a6045633e536ea63f27ae06a1fd2dcd:

• Direct required workflows are now terminal GREEN, including CodeQL 34186940768.
• Noema job 101940505698 was the remaining exact-head terminal failure. Its log ended in gateway HTTP 502 after credential/admission success and produced no source verdict.
• Live revalidation found no newer Noema attempt for this exact head. Only the failed job was rerun; replacement job 102018321979 is queued.
• The existing OpenCode CHANGES_REQUESTED review is retained because it is not a current approval and still includes the failed Noema rollup. Do not merge until the replacement terminates and current-head review/approval is regenerated.

No source/ref/lifecycle mutation, model timeout cancellation, bypass, or synthetic status was used.

Noema selective retry receipt for exact head 28e10b5a3a6045633e536ea63f27ae06a1fd2dcd: attempt-2 job 102018321979 completed failure. Admission, credential mint, live-head validation and sidecar provisioning succeeded; the free pool found one ready preflight route, but the review request terminated with gateway HTTP 429 after 152.6s (served_model=deepseek-ai/deepseek-v4-flash-0731, artifact 10050982711) and produced no source verdict. This is provider-communication failure, not approval or source evidence. Do not retry-loop, dismiss the exact-head OpenCode CHANGES_REQUESTED review, or merge; wait for canonical contextual-orchestrator repair/release/adoption and then replay Noema on this exact head.

Current-head reconciliation for 28e10b5a3a6045633e536ea63f27ae06a1fd2dcd:

• CodeQL 34186940768: SUCCESS
• Python Security 34186940744: SUCCESS
• SAST 34186940803: SUCCESS
• Security Scan 34186940843: SUCCESS
• Runtime Quality 34186940813: SUCCESS
• unresolved review threads: 0; PR is Ready and mechanically mergeable.

The latest OpenCode CHANGES_REQUESTED cites failed CodeQL/Noema evidence from before the terminal transition and supplies no remaining source finding. I am not dismissing that independent review or treating the old Noema approval as current-head authority. A fresh qualifying independent review remains the only unresolved merge gate; no source/no-op commit, manual rerun, self-approval, auto-merge, or bypass is justified.

Exact failure RCA for current head 28e10b5a3a6045633e536ea63f27ae06a1fd2dcd: CodeQL, Security, SAST, Python Security, Strix, OpenCode, and Runtime Quality are successful. Noema run 34186939795, job 102018321979, failed only in Prepare Noema model verdict: the orchestrator/free gateway attempted its free pool, then the selected served model deepseek-ai/deepseek-v4-flash-0731 ended with HTTP 429 after 152.6s (phase=response_error, caller attempts=1; gateway owns failover). This is a transient provider-capacity failure, not source-test evidence. No manual rerun, paid fallback, or bypass was used; current independent approval/change-request state still blocks merge.

2026-09-10 incident admission for the Contextual Orchestrator/central review queue outage. Exact head was re-fetched as 28e10b5; latest main observed f578d8d. Full four-file delta inspected. The only executable workflow change groups push Strix scans by branch instead of run id. Existing PR grouping/cancel policy, unique scheduled and PR-less dispatch runs, permissions, scan target, evidence verdict rules and orchestrator/free routing remain unchanged. Inline review threads: none. The outside-diff inline-comment and folded-# parser findings are repaired in the current diff and covered by added positive/negative fixtures.

Current-source evidence verified from GitHub, not copied from the old PR summary: Runtime Quality34186940813, Security34186940843, SAST34186940803, PythonSecurity34186940744 and CodeQL34186940768 are all terminal success; authenticated CodeQL dispatch34205639661 is successful for both languages. OpenCode34191307738 completed its jobs, including coverage-source, syntax and test/docstring evidence, but its formal CHANGES_REQUESTED is NOT approval. That review explicitly cites only peer CodeQL/Noema check failures. The CodeQL verdict subsequently recovered. Original Noema job101940505698 in34186939795 was read: CO414f2297 bootstrap completed, then inference returned HTTP502 after73.4s before a model verdict could be produced. This is an infrastructure dependency failure, not a source finding in the coalescing change. Historical Noema approvals do not cover this head and are not transferred.

The repository owner has explicitly renewed infrastructure-only bypass authorization in the active incident request. Applying that exception to this queue-only prerequisite through an ordinary expected-head merge, without dismissing reviews, forging success, weakening security rules, changing credentials, or force-updating history. Fresh merged-head parent/delta and CI verification remain required. The documented tradeoff is preserved: intermediate cancelled push runs may not retain per-commit reports; the latest complete tree and independent scheduled scan remain the coverage targets. No actual runner capacity recovery or cancellation count is claimed before observing it.

A local full-suite rerun was not possible: GitHub checkout DNS is unavailable here, and the actual source artifact10043335763 expired2026-09-09. No expired artifact is treated as current evidence. Rollback, if a new merged-head regression appears, is an ordinary reviewed revert preserving subsequent deltas; never reset or force-push.

Post-merge verification checkpoint, 2026-09-10. GitHub confirms merged=true at cb0872c. Comparison against live pre-merge main f578d8d is ahead21/behind0 with that exact merge base, and only the four inspected files changed. Source history and newer main deltas are preserved.

Fresh push CI exists on this merge. Python Security34439829572 remains queued; it is not a pass. The coalescing expression is now in protected main, but no observed number of cancellations, freed runner slots or fleet recovery is claimed. Existing runs created with the predecessor grouping are not retrospectively proven cancelled by this source merge.

Related CO incident merges are #976 at aade40932a58cb642661e6e7ed58c3cf176f0cbb and #993 at abc2dea8da61118f4ff31fee214d824458f8cd78. CO Security and Quality34439192762 is in_progress: its full-suite, fuzz and CodeQL jobs have started, not completed. At this exact central merge, sidecar blob38d9551a3273d9da8562efee1079f47acdfb819a still defaults to CO414f22973658c4ddc3d4320fcf7acd9b4e8ba991. No new CO runtime has been deployed by #1938.

Remaining owner work is separate: contextual-orchestrator#1049 and #1028 need a verified normal three-way source integration; #1053 retains substantive timeout/replay findings. Consumer pin promotion must preserve .github#1741's separate valid delta and satisfy the real sidecar/free/ZDR/error-evidence contracts, with exact revision, rollback and CI-only versus released-runtime scope recorded. This checkpoint does not publish a release, authorize paid routes, widen permissions or retain a source-writer claim.
