Conversation
…roup per run id
The workflow-level concurrency key fell back to github.run_id for every
non-PR event, so each main push was its own group and no newer main head
ever retired an older, superseded scan. Measured 2026-09-05T14:27Z in
.github: nine push/main Strix runs outstanding at once (five running, one
past two hours; four queued) against a 10-30 minute normal scan, each
holding a slot under the shared 60-job ceiling.
Scope push events as push-<ref_name> with the existing cancel-in-progress:
true, so a newer head of the same protected branch supersedes the older
scan exactly as a newer PR head does. A push scan covers the whole tree and
publishes no strix commit status, so the newest head subsumes every older
one; schedule and PR-less repository_dispatch keep a unique run id and the
pr_number admission output is unchanged.
Contract: queue-contract docstring records the measurement and a new
assertion pins the push-{0} clause; the quick gate asserts it too; the
2026-09-04 doctoring record carries a dated amendment.

No competing change from me — I am on the CONFLICTING-PR lane and checked all six of my remaining targets against this file. Only 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 With Against your 10–30 minute normal scan, only 27–49% of main push scans would run to completion; the rest are superseded mid-flight.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 If you want the stronger version, Two notes on your know-how, both confirmed independently here today:

CI note on head 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 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. Generated by Claude Code |

On the 551 s / 429 failure (run The gateway does fail over on a 429; the code cannot surface a rate limit without trying the other routes. What this run actually served. Sidecar at 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 Refinement for the duration fingerprint: |

Noema LLM review
The PR changes Strix workflow concurrency grouping for push events from a unique run-id-per-run group to a per-protected-branch group (push-), enabling newer push scans to cancel older ones and preventing accumulation of duplicate scans that previously blocked runner slots. Changes are consistent across workflow definition, documentation, and tests.
Reviewed changed lines
.github/workflows/strix.yml:84 (RIGHT): Concurrency group expression uses folded scalar and evaluates push events to push-; PR events still use numeric PR number, and schedule/dispatch without PR fall back to run id..github/workflows/strix.yml:85 (RIGHT): Expression parts ensure push groups are prefixed with 'push-' and cannot collide with numeric PR groups; verified against allowed locations.
Adversarial validation
.github/workflows/strix.yml:85 (RIGHT)falsified: The push-specific concurrency group could collide with an existing PR group for the same repository, causing PR scans to incorrectly cancel push scans or vice versa. — Diff at .github/workflows/strix.yml lines 80-96 (RIGHT) shows the parenthesized push condition inside the group expression; PR branches remain numeric and push branches are prefixed, so no collision..github/workflows/strix.yml:84 (RIGHT)falsified: The change introduces a quoting or YAML parsing issue in the concurrency group expression that would break workflow validation. — Diff shows consistent indentation and parentheses; no YAML parsing step in the added tests would be affected, and both tests confirm expected literal text.- Residual risk: Residual risk is low. The coalescing of push scans per branch deliberately drops per-commit evidence for intermediate heads during merge bursts; this is documented and accepted. The weekly schedule scan remains as a floor. No blocking correctness or security issue identified.

This branch's push-clause assertion is re-pointed at group_value for the same reason, and the reason is now stronger here than on main: this branch adds prose to the concurrency block that quotes the push clause, so asserted against the whole block it would pass whether or not the expression survived.

…slice workflow_level_concurrency_group() dropped whole-line comments but kept an inline one, so `group: <collapsed> # <documented expressions>` still satisfied every substring assertion while the real key had collapsed. The existing negative control only covered a comment above the key. Stripping follows YAML's own rules rather than cutting at the first `#`: a comment opens only at line start or after whitespace, and never inside a quoted scalar. Only the key's own line is stripped -- inside a folded block body `#` is literal content, so cutting there would corrupt a legitimate value. Two controls added: the inline-comment shape, which fails without this change, and a shape that must survive it (a quoted scalar containing `#` and a folded body containing `#`).

@coderabbitai The inline-comment finding is correct and is fixed in Reproduced first. With the helper unchanged, the shape you describe passes every assertion: The real key is collapsed to the repository alone and the contract stays green. Where I did not follow the suggestion. The prompt asks to "parse the scalar according to YAML comment rules" over the group value. Applied to the whole value that would be wrong, because this workflow's key is a folded block scalar ( Stripping also follows YAML's actual rule rather than cutting at the first Two controls, not one. Beyond the inline-comment fixture you asked for, I added the converse — a shape that must survive stripping — because a naive fix here is as dangerous as the bug:
The first control fails without the change and passes with it; the second passes both ways and exists to keep a future "just split on Gate on Note the helper itself arrived from #1970 on main, not from this branch. I fixed it here rather than opening a separate PR because this branch's own push-clause assertion depends on it, and this branch is what makes the weakness reachable — it adds docstring prose quoting the push clause verbatim. If you would rather see this land as its own change against main, say so and I will move it. Generated by Claude Code |

Resolves the conflict #1975 introduced in tests/test_required_workflow_queue_contract.py. Main replaced the hand-rolled block slice with WORKFLOW_LEVEL_CONCURRENCY_BLOCK, added a literal-scalar refusal, and folds `>` scalars by joining the body lines, which drops the indicator line. Both sides are kept. #1975's parser does not strip an inline comment from a plain scalar: its plain-scalar path returns the group line verbatim, so `group: <collapsed> # <documented expressions>` still satisfies the substring assertions. Reverting only _strip_yaml_inline_comment on top of this merge still fails test_concurrency_group_slice_ignores_an_inline_ comment_on_the_key, so the helper remains load-bearing rather than superseded. The folded path needs no stripping: #1975 discards value[0], where an inline comment after `>-` would sit, and the body lines it joins are literal content where `#` is not a comment. Gate: 2966 passed, 1 skipped, 21 subtests, coverage 100%, interrogate 100%.

strix.yml's workflow-level concurrency key falls back togithub.run_idfor every non-PR event. Forpushevents that meant everymainpush was its own group, so no newermainhead ever retired an older, still-queued or still-running scan of a superseded commit. This PR scopespushevents aspush-<ref_name>(strix-security-scan-<repo>-push-main), keepingcancel-in-progress: true, so a newer head of the same protected branch supersedes the older scan exactly as a newer PR head does.scheduleand PR-lessrepository_dispatchruns still get a unique run id; thepr_number=${GITHUB_RUN_ID}admission output is unchanged.Why — measured 2026-09-05T14:27Z in this repository

Five of them held runner slots under the shared 60-job ceiling that the required PR reviews are starving behind; the other four waited in the queue and occupied no slot until a runner was assigned.

It is not a record of every earlier commit's findings — code that entered and left between two heads, or findings a retired run never uploaded, are absent — and a per-commit retention guarantee would need a separate preservation contract this PR does not add.strixcommit status (bothstatusesPOSTs are keyed onPR_HEAD_SHA); the workflow holds nosecurity-events/issuespermission, so push runs produce only the run artifact.schedulescan keeps a unique run id and is never cancelled by this change.This reverses one sentence of

User experience
