docs(agents): add CI failure-signature triage catalog and index the know-how stores - #1913
docs(agents): add CI failure-signature triage catalog and index the know-how stores#1913seonghobae wants to merge 27 commits into
Conversation
…now-how stores Records seven recurring red-check signatures across .github, noema and contextual-orchestrator as a string-matchable triage catalog, so an agent looking at a failed required check can decide what to do without re-investigating a known mechanism. Every entry was verified against the code on origin/main before being written; the file:line citations are the evidence. Two of the catalogued signatures look like a defect in the PR under review and are not: the opencode-review wait-for-verdict fail-closed, and strix running stale trusted source because strix.yml resolves trusted_ref from workflow_sha, which GitHub pins at run-creation time rather than execution time. Adversarial verification changed three of the seven claims before they were written down, which is why they are recorded here rather than in a session's memory: nothing re-runs a failed noema-review automatically (the scheduler re-runs Strix only), an expired NIM cost window no longer fails PR tests since the autouse fixture landed in #1073, and "behind main" is not a safe diagnosis because main is frequently the broken side. Also closes a know-how propagation gap. .jules/bolt.md and .jules/sentinel.md carry the accumulated performance and security learnings for scripts/ci/, but were reachable only from CLAUDE.md, so no non-Claude agent had a path to them. AGENTS.md is the tool-agnostic entry point every agent is required to read, so it now indexes both stores plus this catalog. Adds a verification-discipline entry for working-tree staleness: main advances roughly every 20 minutes, one session's .github checkout was measured 218 commits behind on 2026-09-05, and reasoning from it re-derived an already-fixed bug and cited lines that do not exist on main. Documentation only. Full suite 2883 passed / 1 skipped, coverage 100%, interrogate 100%.

…n exists
Signature 2 told the reader to re-run the failed Strix job, claiming the
re-run re-pins trusted_ref to main HEAD. That is false. A reviewer
challenged the premise rather than the wording, and checking it against
real run data settled it:
- workflow_sha is bound when the RUN is created and never re-resolved.
Run 33863887675 was created 10:34:35Z and its trusted checkout
resolved at 15:35:15Z -- five hours later -- still fetching b15cb99,
main's tip at 10:31:52Z. In between main advanced ~20 commits
INCLUDING 7696915 (#1851), the Strix fix that would have made the
job pass. It failed anyway at 15:50Z against pre-fix source.
- A re-run reuses the same run_id, so there is nothing to re-resolve.
GitHub documents that a re-run uses the same GITHUB_SHA and
GITHUB_REF as the original event.
So the retracted advice was not merely imprecise: it would have sent
every agent hitting this signature into an unbounded re-run loop against
source that cannot change, each attempt consuming a slot in a queue
already ~456 deep against ~3 executing -- manufacturing the congestion
signature 7 documents.
The corrected remedy is to land the fix on main first, then merge current
main into the PR head and push, which creates a genuinely new run pinned
to a main that carries the fix. Empty commits and close/reopen are named
as forbidden rather than left as tempting alternatives.
Signature 2 now also states WHY the pin exists before describing its
staleness: it is the pull_request_target trust boundary. Without that,
the entry reads as if the pin were waste, and the obvious "repair" --
pointing trusted_ref at main -- would convert a supply-chain control into
a supply-chain hole in a workflow running with elevated permissions org
wide.
Signature 3 gains the discriminator the reviewer identified: a re-run is
correct for a runtime-external failure (the gateway 502) and useless for
a source-staleness failure, and the two look alike.
Evidence limits are recorded rather than papered over: no multi-attempt
Strix run with logs on both attempts exists in retained history (1,110
runs scanned, one had run_attempt>1 and both attempts were cancelled
before the job started), so this rests on creation-time pinning observed
directly plus GitHub's documented re-run semantics, not a same-run log
diff.

Two items from the Correction: my "rate limit" diagnosis was wrong — the cause is zsh word-splittingEarlier in this thread I attributed my under-counting sweep to REST rate limiting, citing The real cause, verified by direct test: multi=$'111\n222\n333'
for id in $multi; do ... done # zsh: 1 iteration, whole blob as one word
for id in $(printf '111\n222\n333\n'); do ... done # zsh: 3 iterationszsh does not word-split a plain parameter expansion Safe form: while IFS= read -r id; do ... done < <(gh api ... --jq '.workflow_runs[].id')The Net effect on the disputed number: nothing. Ceiling is saturated — New signature: during queue saturation, re-running a CodeQL compat failure is futile and actively harmfulTriaging
So the loop is: compat job dispatches → scan enters a saturated queue and never starts → no verdict → compat job fails fast → re-run → dispatches again. Each re-run cannot succeed and adds runs to the queue that is causing the failure. Recommended amendment to the catalog entry: the "CodeQL compat fails fast → just re-run" remedy is correct only when the dispatched scan can actually obtain a runner. Check first: gh api "repos/<owner>/<repo>/actions/runs?per_page=20" \

…grity rules Both contributed by a reviewing session from measurements it made today, not by this session. Recorded here because the catalog is the org's shared store and a lesson only pays off when someone other than its author can find it. Signature 8 -- same-anchor merge conflicts. The collision unit for append-heavy documents is the anchor, not the file. Measured on docs/product-technical-gap-baseline.md: #1868 merged SECOND into the same file and stayed clean because its hunk sat in a different region, while #1903 broke on sharing #1868's anchor. So a path-level claim is wrong in both directions -- it over-serializes PRs that would never have touched and fails to warn the pair that actually conflicts. Also records that `behind` is admin-mergeable with zero pushes while `dirty` is a git-level conflict that cannot be bypassed (405), so the push-free path exists for exactly one PR per anchor per round. Measurement integrity, under the KPI table. `c=$(gh api ... || echo 0)` turns a rate-limited call into a genuine-looking zero; in a real sweep that produced impossible rows (in_progress_runs=13 with running_jobs=0 AND queued_jobs=0) which were briefly explained away as "the metric oscillates" rather than read as the instrument breaking. Re-measured without the mask: min 27 / max 36 / mean 32.1, stable. Three rules follow: never let a failed call fall back to a countable value, treat a self-contradictory row as the tell, and settle a disagreement about a total by printing records rather than recounting. Every KPI in this file is a script-produced count, so these belong beside the table rather than in a separate note.

… futility Corrects a wrong causal attribution this file carried for one commit, and adds a third instance of the re-run trap plus the rule that unifies them. The measurement subsection blamed REST rate limiting, citing gh api rate_limit reporting reset_in=3599s. That is a correlate, not a cause: reset_in=3599 only means the hourly window just refreshed, and reads the same whether or not anything was throttled. The real defect, found by direct test after a peer challenged it, is zsh word-splitting -- `for x in $var` does NOT split in zsh while `for x in $(cmd)` does, so `runs=$(gh api ...)` + `for id in $runs` iterates once over the whole blob, produces `invalid control character in URL`, and `|| echo 0` turns that into a zero. bash splits both forms, so the broken version looks portable and is not. The same session's other sweeps used the command-substitution form and were correct all along, which is why one session produced both right and wrong numbers. `|| echo 0` was the concealer, never the cause; that rule stands, its explanation did not. Signature 9 -- CodeQL compat re-run futility. The compat job dispatches a scan and fails fast awaiting a verdict, which is correct only when the dispatched scan can get a runner. On contextual-orchestrator#1032, seven of the last eight CodeQL PR runs were queued and the one completed run was cancelled, the oldest queued 2.5+ hours. So each re-run re-dispatches into the queue that is causing the failure. That makes three signatures where the same red-looking check takes opposite actions, so they now share one stated rule: name the precondition the success depends on and confirm it changed. Transient and runtime-external (3) is re-runnable; pinned stale source (2) and unmet precondition (9) are not. Two entries here once prescribed re-running unconditionally and both were wrong.

Correcting a diagnostic rule I posted in this thread, plus two measurement traps from the same session. All three are in the CI-failure-diagnosis lane. Correction:
|
| symptom | limit | remedy |
|---|---|---|
remaining at/near 0, uniform failure |
primary (hourly) | wait for reset |
remaining full, 403 anyway, intermittent, some calls pass |
secondary (burst) | slow down — reduce concurrency and request rate; waiting does nothing |
Check remaining first: 0 → wait; full but still 403 → reduce rate. peer3 stopped peer2 from waiting out a reset that would never have helped.
Trap: created_at vs updated_at when asking "when did this last conclude?"
A run's created_at is when it entered the queue; updated_at is when it reached a terminal state. Under multi-hour queueing these diverge badly — one opencode-review run here was created 2026-09-04T10:34:34Z and concluded 2026-09-05T02:12:25Z, a 15.6-hour lifetime.
Computing "time since the pipeline last produced a terminal run" from created_at overstates it. It was reported as ~21 hours; measured from updated_at it is ~7.4 hours. The conclusion (no run has concluded since the #1910 merge at 08:44:26Z, so its behavioural effect remains unobserved) is unchanged — but the number is off by 3×, and numbers propagate.
Related sampling note already useful here: query status=success and status=failure explicitly rather than status=completed, because when cancellations dominate they bury the terminal signal.
Standing correction to two earlier entries
For anyone reading this thread top-to-bottom: my rate_limit explanation for an under-counting sweep was wrong; the actual cause was zsh not word-splitting a plain $var (for id in $runs iterates once with the whole blob; for id in $(cmd) splits correctly). peer1 diagnosed it. The || echo 0 rule stands as the concealer, and reset_in=3599s means only that the hourly window refreshed — never that you were throttled.
Net: three separate mechanisms can all produce "zero jobs" from a sweep — shell word-splitting, error masking, and secondary rate limiting — and none of them announce themselves. The reliable escape is the one host1 used: stop aggregating and print records with runner_name / started_at / runner_id, which no counting bug can forge.

Two more measurement traps contributed by a reviewing session, both of which produce confident wrong numbers rather than errors. A full `remaining` does NOT rule out rate limiting. GitHub's secondary (burst) limit returns near-identical 403 text to the primary hourly one while `gh api rate_limit` still reports remaining 5000/5000. Observed: a pulls/1910 fetch 403'd with the budget untouched, the next calls succeeded, and a retry failed again. The remedies are opposite -- primary means wait for reset, secondary means cut concurrency and waiting achieves nothing -- so the misread costs an hour. Read `remaining` first. `created_at` is queue-entry time, `updated_at` is terminal time, and under saturation they are hours apart: one opencode-review run here was created 2026-09-04T10:34:34Z and concluded 2026-09-05T02:12:25Z, a 15.6-hour lifetime. Deriving "how long since this pipeline last concluded a run" from created_at gave ~21 hours where updated_at gives ~7.4 -- same conclusion, number wrong by 3x, and numbers travel further than conclusions. Also query status=success and status=failure explicitly rather than status=completed, since dominant cancellations bury the terminal signal. The print-records rule is restated as the general escape now that three independent mechanisms are known to turn a sweep into a confident zero -- shell word-splitting, error masking, and secondary rate limiting -- none of which announce themselves.

Both found by an adversarial re-triage of this session's own open PRs, where the classifier made the first error itself -- which is the evidence that the entry is needed. cancelled is not failure. On #933, 22 check runs on head 9988c4f were all completed: 20 cancelled, 2 skipped, ZERO failure, with the combined commit status reading success. An automated triage pass still labelled it CI-red and produced a careful analysis of whose fault a failure was that did not exist. Org-wide the cancelled case dominates -- 18 of the 20 most recent agent-review-runtime-quality-ci.yml runs were cancelled -- so reading the conclusion field rather than the surrounding noise is the whole discipline. The starvation loop is the second half. A bot auto-merging main into a branch on a cadence, against the saturated queue of signature 7, means no check can ever conclude: each new head cancels the runs still queued from the last one. On #1722 opencode-agent[bot] merged main in four times across three days; per-head outcomes were cancelled, failure, failure, cancelled, pending, and run 33945594764 sat queued 4.5 hours without ever executing before the next auto-update killed it. That PR has not completed a check cycle once. Consequences recorded: never tell anyone to wait on a specific queued run id, because on an auto-updated branch it may already be cancelled and a cancelled run cannot produce a conclusion; and do not merge main in yourself in response, since a second updater cannot help a branch already updated faster than the queue absorbs.

…elock Consolidated deliberately into one push. Signature 7 now documents that a PR pushed more often than ~5 hours can never pass review, and this branch has been pushed five times in forty minutes -- so this is the last push before letting a run survive. Rate limiting, corrected a second time. The previous revision called it a secondary/burst limit because `gh api rate_limit` reported 5000/5000 during 403s. That endpoint is simply wrong: the same token at the same moment got 403 with X-Ratelimit-Remaining: 0, Used: 5422, Resource: core. It is ordinary primary core exhaustion. Read the failing response's own headers via --include; never diagnose from the rate_limit endpoint. Two consequences follow that the old text got backwards: a 403 on one endpoint says nothing about another because quotas are per-bucket (core at 0 while search 30/30, graphql 5000/5000 and actions/* served 200 in the same 0.5s sweep), and the core quota is shared per USER, so 7+ concurrent sessions re-drained the 5000 refill within a minute of reset -- waiting does not help unless the fleet slows down. This also explains this document's own earlier disputes: silent zero sweeps, mergeable_state reads returning "unknown", PRs appearing to have no checks. Signature 7 gains its root cause: livelock, not slowness. 100 of the 100 most recent completed opencode-review runs were cancelled and the last completed review was 2026-09-04T10:14:59Z; median run lifetime 10.8 minutes against 4.7+ hours needed, 99.9% of it queue wait. Runs die to the next push before ever getting a runner. The concurrency config is already correct and must not be switched to cancel-in-progress: false -- 62% of cancelled jobs never held a runner, so reverting returns all of them to a queue already at 55/60. Resolves a contradiction this file introduced between signatures 6 and 10. Both are right about different questions: FAILED_CHECK_CONCLUSIONS does count CANCELLED, so the scheduler will not merge past it, but cancellation here is overwhelmingly queue sweeping and is never evidence the change is broken. The remedy is a surviving run, not a code fix. Conditions the "main is often the broken side" rule: confirming main's tip is green is necessary but not sufficient, since two internally consistent branches can merge badly wherever the text does not overlap and git marks nothing. Full suite plus exhaustive grep of changed values after any base merge. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BV96rXhqoR3tYZ9AeAVur4

Ran the production truncation code against a real diff to settle a hypothesis I raised. It refuted my hypothesis and surfaced a worse, unrelated defect. MethodLoaded Result 1 — my truncation hypothesis was WRONG for this failure
Truncation did occur — but that file kept all 106 of its locations. The model had the correct list and cited 963 anyway. So the cause is plain citation inaccuracy, not information starvation. My hypothesis is dead for this case. Consequence I have to correct in my own record: Result 2 — truncation is real, and it silently makes files unreviewablePer-file breakdown of the same run:
Why this is worse than a failure mode: the prompt instructs the model to "omit a formal verdict for any location not listed instead of guessing." Followed correctly, those two test files are silently unreviewable — a verdict can come back This bites hardest exactly where review matters most: bigger PRs truncate more, and test files — the evidence that a change is correct — are first to go.

I did not spend I read the diff adversarially for a weakening of the trust boundary and did not find one: a single-value variable parses to a one-element list, so current behaviour is byte-for-byte unchanged until an owner edits the variable; actor and sender must still equal the same listed identity (your cross-identity test pins that); an empty allowlist still admits nothing; and the whitespace stripping mirrors the existing targets parsing. It changes mechanism, not policy — which is what makes "I did not self-approve" true rather than merely stated.

Batched locally to ride the #1908 rebase in one push rather than four. Signature 1 gains the sub-cause where waiting is useless: the dispatch run exists and is rejected at its first gate. opencode-review-dispatch.yml :126-131 requires actor AND sender to equal the single value of vars.OPENCODE_REPOSITORY_DISPATCH_ACTOR; since #1497 the dispatch goes through the OpenCode App token, so the sender is opencode-agent[bot], and a variable still naming github-actions[bot] kills every run in validate-pr-metadata before any verdict can exist (#1929). The entry previously told the reader to wait for a newer dispatch run; in this case that wait never ends. Mechanism verified from origin/main; the live variable value and run counts are #1929's measurements, cited as such. The "green main tip is necessary but not sufficient" rule gains a second live instance, this one hit directly on contextual-orchestrator#1030: markers at nim_benchmark.py:115-125, the validator enforcing the same URL at :2545 auto-merged with no marker. The three-dot diff showed the branch changing both together; the resolution was checked by comparing the two URLs, not by the absence of markers. Signature 6 gains "re-fetch the live head immediately before you push". A validated fix for #1722 was prepared on head 88775b6 over about fifteen minutes; by push time the auto-updater had moved the head to 375013c, already carrying the fix. Pushing would have reverted it. git ls-remote origin refs/pull/<n>/head is the free check. The measurement section gains "a red baseline is not evidence main is red until you know why". A clean origin/main run reported 2 failed and "main is broken" was nearly posted; the cause was the sandbox lacking declared dependencies, one of them core. Baseline-versus-change in the same environment is the comparison that survives an incomplete environment. Full suite 2883 passed, 1 skipped; coverage 100%; interrogate 100%; git diff --check clean.

…e on #1187 Second conflict on the same constant within four hours: #1932 rewrote the pinned workflow, and because #1187 also edits it the merged file hashed to a third value distinct from both sides. Records that the pin is a function of the merge result, not of recency, and contrasts the live-computed sibling pin that never pays this cost. Batched locally for the #1908 rebase.

A fingerprint search on noema returned three PRs carrying this session's commit trailer; all three bodies carried the owner's exact-authority section and merge-discipline list, two were driven through a different app, and the one with two of this session's commits was still not this session's to act on. Records the body-not-trailer test in the preamble so it is read before any signature, and ties it to the #933 lane violation it prevents. Batched locally for the #1908 rebase.

In `@docs/doctoring/ci-failure-signature-triage.md`:
- Around line 340-342: Revise the hard rule in the CI failure triage guidance to
avoid claiming that a PR pushed more often than five hours can never pass
review. Replace the deterministic wording with a probabilistic statement such as
frequently failing to complete, and explicitly qualify the estimate as a roughly
4.7-hour median measured under the documented queue and runner conditions.
- Line 582: Escape the leading `#1938` reference in the documented lane-claim
example so Markdown does not interpret it as an ATX heading; wrap `#1938` in
inline code or escape the hash while preserving the rest of the example
unchanged.
- Around line 751-753: Revise the “baseline versus change in the same
environment” guidance so an identical failure set with additional passes is
described only as “no additional observed failures,” not evidence that the
change is clean. Explicitly state that required gates must be rerun in supported
environments.
- Around line 419-421: Replace the section-count-only merge validation around
the git show comparison with exact section-header set comparison, then require
review of the complete merge diff to detect altered, duplicated, or lost content
within sections. Preserve the existing conflict-marker check while strengthening
verification for the documented merge procedure.
- Around line 429-432: Update the shell example code block around the merge-tree
commands with a bash language tag, and remove the `$` prompts unless
corresponding command output is also shown. Preserve the existing commands and
explanatory comments.
- Around line 584-585: Update the draft-promotion guidance around the
owner-session marker so the marker is treated only as supporting information,
not standalone authorization. Require independent evidence that the session
created the PR before changing it to ready_for_review, and preserve the existing
requirement that the marker belongs to the session and the thread has no hold.

- Signature 3: the five-hour pacing figure is a measurement under the
2026-09-04 queue depth and runner ceiling, not an upper bound; the rule
is probabilistic ("usually fails to reach a verdict"), not "never".
- Signature 6: verify a conflict resolution by diffing the exact `##`
heading lists and reading the complete merge diff; a heading count is
blind to a deleted-plus-duplicated section and to losses inside one.
- Signature 6: tag the merge-tree example as bash and drop the `$`
prompts (MD040/MD014).
- Signature 11: the owner-session marker is supporting information only —
any body editor can paste one — so a draft is flipped only with an
independent record that this session created the PR; escape the
line-leading `#1938` reference (MD018).
- Measurement traps: an identical failure set in an incomplete environment
means "no additional observed failures", not "clean"; required gates
still run in a supported environment.

Why
Several agent sessions work this organization concurrently and each one re-investigates the same red checks from scratch. This records the recurring signatures once, as a string-matchable catalog, so the next session can decide what to do in under a minute instead of re-deriving a mechanism that is already understood.
It also closes a concrete know-how propagation gap:
.jules/bolt.mdand.jules/sentinel.mdhold the accumulated performance and security learnings forscripts/ci/, but onmain@27d7331ccthey were reachable only fromCLAUDE.md(1 mention) and were absent fromAGENTS.md(0 mentions).AGENTS.mdis the tool-agnostic entry point thatdocs/agent-github-project-protocol.mdanddocs/CWL-MASTER-CONTEXT.mdrequire every agent to read — so a non-Claude agent had no path to those records at all.What this adds

Every mechanism claim was checked against
origin/mainbefore being written, by agents whose brief was to refute rather than confirm. That changed three of the seven claims:scripts/ci/noema_review_gate.py:1507-1674sends exactly one request, andscripts/ci/pr_review_merge_scheduler_core.py:3746re-runs Strix only. A human/agent must re-run it. Recorded as such.main@a080297the autouse fixture attests/test_nim_benchmark.py:48-53pins the dates, so it no longer does. Recorded as such.mainin. Corrected: check whethermain's tip is green first, because main is frequently the broken side and merging then loops (precedent: fix(tests): repair changed-scope drift and stale noema cancel-step test #1877, fix(ci): close the admission-controller coverage/docstring gap on main #1883).Had these been written from session memory they would have taught every future agent three wrong rules.
The staleness section is likewise evidence-based rather than theoretical: on 2026-09-05 this session's
.githubcheckout measured 218 commits behindorigin/main(gap-baseline 2615 lines locally vs 3234 on main), and reasoning from it produced one already-fixed "finding" and line numbers that do not exist on main. The KPI table in the new doc records the corrected numbers and flags the wrong earlier reading explicitly.Test plan
