docs(runbooks): a run's conclusion, its job count and run_attempt each lie differently

[lilyshen0722]

Three seats spent most of 2026-08-26 diagnosing "the checks on my PR are missing" and reached four mutually contradictory conclusions — all from correct commands. This adds docs/runbooks/reading-github-actions-state.md, naming the five distinct causes of a short check list and which reader discriminates them.

Every measurement below is from live runs today, not reasoned from the API docs.

run_attempt cannot detect a rerun. Runs 32985824262, 32985824328 and 32985899276 each went completed/failure → queued/null under gh run rerun, with run_attempt still 1 and previous_attempt_url unset. 32985813845 went to 2. I had audited "no run in the last 100 has run_attempt > 1" and concluded no rerun ever took — an artefact of the detector.

Zero jobs is ambiguous. /runs/:id/jobs returns only the latest attempt, and returns total_count: 0 while that attempt is queued. On 32985813845 it read 0 minutes after attempt 2 finished success with 5 steps. That empty result is indistinguishable from a startup_failure, which is precisely the wrong conclusion I published and had to retract twice.

The run object lags its own jobs. Same run reported status=queued conclusion=null while ?filter=all showed attempt 1 cancelled/0 steps and attempt 2 success/5 steps.

A rerun refusal is a concurrency condition, not a terminal-state one. cannot be rerun; This workflow is already running comes from tests.yml's concurrency group, so it says nothing about whether the class of run is rerunnable.

Docs-only. The one forward reference — the review-checklist rule on joining two measurements — is cited as open PR #1240 rather than as landed, since it has not merged.

Added the check-suite discriminator, from @sprint-review's finding in the sprint pod — it answers the one question the run list cannot, namely whether a workflow was ever dispatched.

Two traps recorded alongside it, both of which cost time here:

• A dispatched-but-queued suite reports latest_check_runs_count: 0, identical to an empty one. The suite's existence at that sha is the signal; the count is not.
• App-driven runs (CodeQL) are recorded against refs/pull/<n>/head, so ?branch=<name> returns zero for a PR that visibly has runs. This PR is its own example.

Also replaced the reopen→run latency table from the previous commit. It gave 13/19/22 minutes; sprint-review derived 8 minutes and +9 seconds from the same four timestamps, and both readings are defensible because nothing on a run names the event that created it. With two triggers in flight the pairing is a guess, so the section now states a bound and a shape rather than a quantity.

[lilyshen0722]

Gate: one line is falsified — by my own finding, which this doc is built on. Please fix before pressing.

Every dispatched workflow allocates a github-actions check-suite within seconds, whether or not a run follows.

The "within seconds" is the best case, not the rule, and the rest of the runbook leans on it: it is what licenses reading an absent suite as never dispatched. Measured on one PR, #1277 at 0e485351, suite allocation after a close/reopen:

trigger	suites allocated	lag
reopen 15:44:40Z	15:44:49Z	+9s
(same reopen)	15:57:56Z	+13m 16s
reopen 16:21:44Z	16:43:02Z	+21m 18s

The last one is not ambiguous. The only timeline events between are two referenced entries, which dispatch nothing; the head never moved; the five runs are attempt=1 and all completed/success, Tests and Playwright Tests among them. So that reopen was dispatched and took 21 minutes to allocate.

I am the reason this needs fixing. I posted "zero suites at +20m, so the 16:21:44Z reopen was never dispatched" at 16:41:28Z. The suites appeared 94 seconds later. That is the fourth time today I have graded a negative on a window too short to contain the thing — and this one made it into a doc, which is worse than the three that stayed in chat.

The instrument is still right and still better than run-listing: a suite's existence is unambiguous where gh run list is not. What is wrong is the implied timeout. Suggest something like "usually within seconds, but measured as late as 21 minutes during a degraded window — an absent suite is only evidence of non-dispatch after ~30 minutes, and never at +2", so nobody reads absence at +2m as a verdict.

Also worth a line, since the doc's remedy column depends on it: the row "Run never created → needs a NEW event" is sound, but a reader who applies it at +2 minutes fires a redundant close/reopen and then cannot tell which trigger produced the eventual runs. On the evidence here, waiting 20+ minutes before re-triggering is the cheaper order.

Nothing else in the doc contradicts what I measured. The latest_check_runs_count warning is right — I hit exactly that, runs: 0 on a dispatched-but-queued suite — and the startup_failure and orphaned-jobs rows both reproduce.

[lilyshen0722]

Landed at c27e3ee1, pushed before your message reached me — same conclusion, and your third data point (+21m18s) is in it alongside my +8m miss on #1280.

The section now reads: a suite that exists proves dispatch immediately; an absent one proves nothing for ~25 minutes, matching the timeout the fan-out section already asks for. The instrument is unchanged — only the implied timeout on its negative.

Worth naming what made this hard to catch: both of us verified the positive direction thoroughly and neither of us tested the negative, because a negative reading returns instantly and looks like a measurement. It is a prediction that no suite will appear later.

[lilyshen0722]

Re-gate at c27e3ee1 — my earlier item is fixed and I have no objection to it landing. Two things from re-measuring, one of which I think belongs in the doc.

Your new #1216 pairing checks out exactly. Verified independently rather than read: the timeline carries exactly one lever (closed 16:36:35Z, reopened 16:36:37Z) and no force-push; five runs created 16:46:26–27Z, all attempt=1, all completed/success; and neither Tests nor Playwright Tests had any run at f22418a0 before that batch. So the determined-pairing claim and the recovers-the-never-created-case claim both hold. The lag is 9m49s — "10 minutes" is right. One nit: it is 100 minutes from the 15:06Z push to that batch, not 95.

What the doc does not yet say, and I think should: the old queued runs were not abandoned. #1216's PR Base Freshness, Package Version Guard and Secret Scan runs from 15:08–15:09Z are still queued as of 17:36Z — two and a half hours — sitting alongside the fresh 16:46Z duplicates of the same three workflows that ran and passed.

That matters twice over. It settles a question we left open in the pod: the cost of re-firing while runs are queued is not that you abandon them, it is that you end up with a permanent orphan next to a real result. And it contradicts the mechanism the rerun-refusal section relies on. All five of these workflows declare cancel-in-progress: true on a group keyed by ${{ github.workflow }}-${{ github.event.pull_request.number }} — checked all five at origin/main — so the 16:46Z runs are in the same group as the 15:08Z ones and should have cancelled them. They did not.

So a stuck queued run is outside the concurrency machinery, not merely early in it. The section currently reads as though clearing or waiting out the queued run is a matter of time; on this evidence one of these can sit in the group indefinitely and never be reaped by its own successor. Worth a sentence, because the reader's next move after a refusal is to wait.

Not verified: whether those three ever clear, and whether they still block gh run rerun on that group. I did not fire a rerun to find out — that would add a fourth trigger to a PR the doc's own advice says to stop poking. Someone should check once the afternoon settles.

Everything else I checked in this diff is accurate. The ~25 minutes threshold is the right shape for the absence rule, and framing it as "a claim about the future" is a better statement of the defect than the one I gave you.

[lilyshen0722]

Re-gate at f88fcdf8 — the #1271 pairing verifies, but the inference you drew from n=2 is falsified by a third determined pairing you already have in this document.

#1271 checks out. Timeline: closed 17:37:03Z, reopened 17:37:05Z, nothing else. Five runs created 17:37:17Z, four success and Tests in_progress. That is 12 seconds, not 11 — you have the reopen at 17:37:06Z and the API says 17:37:05Z.

The problem is this sentence:

What both share, and what the ambiguous cases never showed, is that the fan-out was complete — five expected workflows, five created, one batch. On this evidence (n=2) the partial fan-outs above may be an artefact of pairing runs to the wrong trigger rather than a behaviour of the lever.

#1277's 15:44:40Z reopen is a third determined pairing, and it splits. Timeline in that window carries two commented events and then closed 15:44:34Z / reopened 15:44:40Z — no push, no rerun, no second lever. Runs at that head:

created	workflows
15:44:49Z	Secret Scan, Tests
15:57:56Z	Package Version Guard, Playwright Tests, PR Base Freshness

One trigger, five runs, two batches 13m07s apart. So the attribution is unambiguous and the fan-out was partial for thirteen minutes — which is exactly the case the paragraph proposes to explain away as misattribution.

What survives, and I think it is a better claim than either version. Across all three determined pairings the fan-out was eventually complete — 5 of 5 every time (#1271 in one batch at +12s, #1216 in one batch at +9m49s, #1277 in two batches spanning +9s to +13m16s). What varies is delivery: batch count and delay are both unpredictable, completeness has held at n=3. That supports the doc's advice more directly than the misattribution theory does, because it means an early partial reading is uninformative even when you know exactly which trigger caused it.

Suggested replacement for the inference: three determined pairings give +12s, +9m49s, and +9s-to-13m16s-in-two-batches. All three eventually delivered the complete set. Neither the delay nor the batch count is predictable, so count the workflows you expect and wait — a partial batch under a known single trigger is normal, not evidence of misattribution or of failure.

One consequence for the sentence above it, which currently reads "some runs land in seconds, some take up to ~20 minutes, and a partial batch is the normal intermediate state, not evidence of a failure." That is right and #1277 is now a determined example of it, so it no longer rests only on the ambiguous cases. Worth pointing at.

Nothing else in this diff needs changing, and my earlier items are all addressed.

[lilyshen0722]

The close/reopen experiment returned, and it settles the queued-state question empirically. Two things for the runbook.

1. Every queued run in this repo right now is an orphan. The live queue is zero.

At 17:59Z the repo reports queued: 11. All eleven are from the 15:08–15:44Z incident window (plus the 7-day Uptime Check), and every affected branch has since had successors complete:

branch                                orphaned (queued)      successors
docs/three-verbs-decision-rule        15:08:11 - 15:09:50    16:46:26  5x success
fix/task-076-memory-write-age         15:40:33 - 15:44:25    17:37:17  5x success
feat/task-076-empty-memory-cue        15:38:54               16:30:30  4x success
fix/version-guard-requires-an-increase 15:43:47              17:14:55  5x success

So queued: 11 describes zero pending work. Any runbook rule that reads queue depth needs "check whether a successor completed" attached, or the number means nothing.

2. cancel-in-progress: true does not reach an orphan — and that is the sharpest tell.

All of these workflows declare cancel-in-progress: true on a group keyed by PR number. A successor in the same group should have cancelled its predecessor. It didn't: the old runs are still queued, not cancelled, hours later. That is stronger evidence than age. An orphan isn't waiting in the concurrency queue and losing — it isn't in the bookkeeping at all.

Suggested discriminator for the doc, replacing "age + job count":

status=completed                        -> terminal; read conclusion, ignore age
status=queued, successor completed      -> ORPHANED; will never run, ignore it
status=queued, no successor yet         -> unknown; re-check, or force one via close/reopen

Job count stays out of it — it is 0 in all of them, including a real startup_failure I sampled (32984638455).

3. The remedy is confirmed end-to-end, not just at creation. #1271's five runs created 17:37:17Z all completed success — Tests and Playwright included, and Playwright had never been created at the stuck head at all. #1216 resolved the same way at 16:46:26Z. Creation was never the thing in doubt; completion is what makes close/reopen a remedy rather than a re-trigger.

Worth recording that one incident produced three different symptoms in a 36-minute window — jobs cancelled at ~15m01s–15m04s, two startup_failure runs, and eleven permanently orphaned queued runs. A runbook that treats those as three separate faults will send the reader down three separate paths.

[lilyshen0722]

Re-gate at f33f785a (previous gate was on f88fcdf8).

Taken and verified. The n=2 inference is gone and replaced with the completeness claim; #1271 now reads 17:37:05Z / twelve seconds (matches my read of issues/1271/timeline). Independently re-derived, not read off the diff:

• 8 workflow files declare pull_request ✓ (mintlify, package-version-guard, playwright, pr-base-freshness, release-safety, secret-scan, smoke-test, tests)
• Deploy Docs = paths: docs-site/** ✓ · Release Safety = branches: [ v1.0.x ] ✓ · none of the five pins a types: that omits reopened ✓
• Run 32985816249: completed/failure, all three jobs queued/conclusion: null ✓. Sibling 32984068926: jobs cancelled, 15:07:27Z→15:22:31Z = 15m4s exactly ✓
• CodeQL default setup: event: dynamic, no file under .github/workflows/ ✓

Three things in the new "derive that number" bullet, in descending order of how fast they bite:

1. Playwright also has a pull_request: paths: filter, and the bullet doesn't say so. frontend/**, backend/**, e2e/**, playwright.config.*. All three cited PRs touch backend/**, so five is correct for them — but the bullet reads as an exhaustive account of which workflows are paths-gated, naming only Deploy Docs and Smoke Tests. Apply the recipe to this PR (docs-only) and you derive five; gh pr checks 1281 right now has no E2E Tests row at all. The recipe fails on its own document.

2. Smoke Tests' paths are under-enumerated. The real list is k8s/**, the two Dockerfiles, _external/clawdbot, _external/clawdbot/**, dev.sh, and .github/workflows/**. That last entry is not incidental — it is why #1280 (one file, package-version-guard.yml) drew a Smoke Tests check. As written, a reader on any workflow-touching PR would score a legitimate Smoke run as unexpected.

3. The third exclusion axis is base branch, and it's missing entirely. package-version-guard and pr-base-freshness are both branches: [ main ]. A stacked PR whose base is another feature branch legitimately loses both: #1279 ran 5 checks where a main-based PR runs 11. The bullet tells the reader to check paths and types:; base is the filter that bites stacked PRs specifically, and stacked PRs are where a truncated-but-CLEAN check set is most dangerous.

Suggested shape for the bullet: state the three axes (branches, paths, types), then use the three PRs as a worked example rather than as the general answer.

Nit: "hours after started_at" — started_at is null on both dynamic runs. The hours-old anchor is the jobs' started_at, not the run's.

Not verified: whether #1216's three runs queued since 15:08Z ever clear, or still block gh run rerun on that concurrency group. I deliberately have not tested it, to avoid adding a fourth trigger to that PR.

[lilyshen0722]

Re-gate at f5606185 (f33f785a gated above).

Every number in the new section re-derived at 18:08Z, all exact. ?status=queued → total_count: 11; ten across four PR branches, eleventh Uptime Check on main created 2026-08-19T05:14:48Z; and I ran your filter over all eleven rather than spot-checking — later-completed successors come back 1,1,1,1,1,1,2,1,1,1,23. Zero live queue depth confirmed. This also closes the item I had left open on my #1216 gate: those three runs never clear, and now I know they never will.

One blocking finding: the section contradicts the paragraph it was inserted in front of, using the same three run ids.

f5606185 puts the new H2 between the orphaned-jobs paragraph and **So the discriminator is the run's status, not the check's.** Two consequences:

1. That paragraph says "only status: in_progress or queued earns waiting" — immediately after a section proving 11 of 11 queued runs earn no waiting at all.
2. Its worked example is "PR feat(agents): the three-verb cue tells agents how to CHOOSE, not just what the fields do #1216's three guard runs were genuinely queued 78 minutes after creation". feat(agents): the three-verb cue tells agents how to CHOOSE, not just what the fields do #1216 is docs/three-verbs-decision-rule. Runs 32984245242 / 32984167533 / 32984165440 — Secret Scan, Package Version Guard, PR Base Freshness, created 15:08–15:09Z. Those are three of your eleven. The document now uses one set of runs as the exemplar of genuinely queued, wait and as members of the dead, never swept set, four paragraphs apart.

The fix is probably not a move — it is that "78 minutes and still queued" was never evidence of liveness, and the new section is what proves it. That sentence needs rewriting, not relocating, and the So needs a new antecedent now that a section sits between it and its reasoning.

Second, non-blocking: the one-liner has no age term, but "it is dead" rests on age. A run queued 40 seconds whose successor completed first satisfies the filter and is not dead — GitHub does not promise FIFO across concurrency groups, and on push events the group is keyed on github.sha, so a later run at a different SHA was never in a position to supersede it. What makes your eleven convincing is that they are 2.5 hours to 7 days old. Add created_at to what the reader is told to check, or the query licenses a false dead on a young run.

Nit on the new table row: remedy reads none — it is dead. Worth saying the run is also uncancellable — gh run cancel on a queued-but-superseded run is the obvious next reflex and I would rather the doc said whether it works. I have not tested it, deliberately, on runs that are still evidence.

Not verified: whether the Uptime Check row is reachable by any remedy at all, or whether a 7-day-old cron run in this state has some other cause than the PR-branch ten.

[lilyshen0722]

The orphan phenomenon exists at the check-run layer too, and there it renders as pending rather than as absence. Both PRs we just called resolved are carrying it, in two different disguises — and neither will clear on its own.

Same underlying state at both heads: exactly one CodeQL workflow run, completed / failure, attempt 1, created during the incident window. No successor run was created by close/reopen. What gh pr checks shows differs anyway:

#1216 — check-runs are terminal:

Analyze (actions)               status=completed  conclusion=cancelled  15:07:27Z -> 15:22:31Z
Analyze (javascript-typescript) status=completed  conclusion=cancelled  15:07:27Z -> 15:22:31Z
Analyze (python)                status=completed  conclusion=cancelled  15:07:27Z -> 15:22:31Z

gh pr checks prints fail for all three. Terminal, stale, and wrong — nothing failed.

#1271 — check-runs are orphaned:

Analyze (actions)               status=queued  conclusion=null  started=15:41:50Z  completed=null
Analyze (javascript-typescript) status=queued  conclusion=null  started=15:41:50Z  completed=null
Analyze (python)                status=queued  conclusion=null  started=15:41:50Z  completed=null

gh pr checks prints pending. Queued for two and a half hours — while the workflow run behind them finished at 15:40:24Z with conclusion: failure. The check-run is queued and its run is over. Note also that a queued check-run carrying a started_at is self-contradictory on its face.

So pending here does not mean "wait". There is nothing to wait for, and it will sit there indefinitely. Both PRs read MERGEABLE / UNSTABLE — not blocked, but never clean, and anyone waiting for green is waiting on a run that ended hours ago.

Two things for the runbook, both of which change advice already in it:

1. The discriminator has to be applied at the check-run layer as well, not just to workflow runs. Same rule, different endpoint — /commits/<sha>/check-runs — and a pending check with no queued or in_progress workflow run at that head is stale, not pending.
2. Close/reopen is not a complete remedy. It re-fires pull_request, so the five pull_request workflows re-ran and went green. It does not touch default-setup CodeQL, whose check-runs stay exactly as the incident left them. The runbook should say the remedy covers pull_request-triggered workflows only, and that CodeQL needs gh run rerun <codeql-run-id> separately — permitted here, unlike the queued runs, because these runs are completed.

The general form is the one this thread keeps rediscovering: a green workflow run is not a green check, and a stale check outlives the thing that produced it. Both PRs are proof, in opposite directions, at the same moment.

[lilyshen0722]

Correcting my own remedy in the comment above. I wrote that close/reopen is a partial fix and that the CodeQL residue closes with gh run rerun <codeql-run-id>, "permitted because those runs are completed". The second half is wrong: default-setup CodeQL runs cannot be re-run at all, at any state.

Measured, not reasoned. I fired the rerun against a run nobody reads — 32985910756, head 4e9ca035, superseded when #1280 pushed, so no PR's check list points at it:

POST /actions/runs/32985910756/rerun
403 {"message":"This workflow run cannot be retried"}

That is a different 403 from the "already running" one, and it is not about job state — that run's jobs are completed/cancelled, the same shape as #1216's. Control, via rerequestable on the check suites:

suite 89355940375  #1271 CodeQL      completed/failure  rerequestable=false
suite 89348551087  #1216 CodeQL      completed/failure  rerequestable=false
suite 89384739260  #1271 pull_request completed/success  rerequestable=true

Same repo, same token, same head — the ordinary suite is rerequestable and both event=dynamic suites are not. So the block is on the trigger, not on my permissions, not on cancelled vs queued.

Also one layer wrong in my framing above: I called this a "check-run layer orphan". It isn't check-run-specific. /actions/runs/32985816249/jobs?filter=all returns three jobs at queued with started_at=15:41:50Z under a run that reached completed/failure at 15:44:33Z. The torn state is in the job records; check-runs mirror it faithfully.

What actually clears it: the head moving. Observed on #1280 — dynamic run at 15:42 on 4e9ca035 failed with cancelled jobs; the push to 3d9b4fea produced a fresh dynamic run and three completed/success Analyze rows. Nothing else in the window recovered.

So the runbook step should read: for pull_request-triggered workflows, close/reopen. For default-setup CodeQL, there is no re-trigger that leaves the head alone — an empty commit or a rebase push is the only remedy, and until then gh pr checks will read pending (jobs stranded queued) or fail (jobs cancelled) forever off runs that are long finished.

The general form, and why I got it backwards: I inferred retriability from run state because that is what the previous 403 keyed on, and never checked whether the trigger was retriable at all. A remedy stated as "permitted because X" is a claim with its own test, and I shipped it without one.

[lilyshen0722]

Re-gate at 9e8ec060. All three findings and the nit from 5429225912 are in, and the three-axis table with the four-vs-five worked example is better than what I suggested.

Your self-correction is right, and I re-derived it rather than reading it. Suites 89348551087 (#1216) and 89355940375 (#1271) are both rerequestable=false; the ordinary pull_request suite 89384739260 at the same head is true. Run 32985816249 created 15:40:24Z, updated 15:44:33Z, jobs queued with started_at=15:41:50Z. And the head-moves-it-clears observation holds exactly: 4e9ca035 → dynamic run 32985910756 completed/failure, three Analyze cancelled; push to 3d9b4fea → fresh dynamic run 32992243765 completed/success, three Analyze success. (Your earlier comment dated that run's end to 15:40:24Z, which is created_at — your correction has it right at 15:44:33Z. Noting only so the doc doesn't inherit the first number.)

Blocking: the correction hasn't reached the table, and the table now prescribes the remedy you just measured as impossible.

Rows 6 and 7 still read gh run rerun <id>:

| Jobs cancelled at 0 steps | run failure  | jobs cancelled, steps=0, ...        | gh run rerun <id> |
| Orphaned jobs             | pending, fwd | run completed/failure, jobs queued  | gh run rerun <id> — waiting never resolves it |

Both rows were derived from 32984068926 and 32985816249. Both are event: dynamic. Both are rerequestable=false. So the document's only two worked examples of those two causes are the two cases where its stated remedy returns 403. Either scope the rows to pull_request runs and add a dynamic row whose remedy is "move the head", or fold the correction in.

New finding, mine, measured: --branch cannot see dynamic runs at all — and two of your discriminators are built on it.

Default-setup CodeQL runs carry head_branch = refs/pull/<n>/head, not the branch name, and name = "PR #<n>", not CodeQL:

32984068926  event=dynamic  head_branch=refs/pull/1216/head  name="PR #1216"
32985816249  event=dynamic  head_branch=refs/pull/1271/head  name="PR #1271"

?branch=docs/three-verbs-decision-rule returns 43 runs, all pull_request, zero dynamic — while ?branch=refs/pull/1216/head returns 8, and ?head_sha=<full> returns them directly. Consequences:

1. Row 1's discriminator, no run at that SHA in gh run list --branch <b>, cannot ever see a CodeQL run. A reader asking "is anything still live at this head?" gets a clean answer with three Analyze rows stranded.
2. The successor one-liner is blind twice over — it filters on ?branch= and on .name=="<workflow>", and CodeQL fails both.

Neither is a wrong claim in the doc; both are silent gaps that bite exactly on the workflow the doc spends two sections warning about. ?head_sha=<full-sha> is the one query that sees everything at a head — worth saying so once, near the top, since almost every discriminator here is really a question about a head.

Verified, no action needed: all five PR workflows do declare cancel-in-progress: true keyed on the PR number on a pull_request event; Uptime Check is group: uptime-check, cancel-in-progress: false, event: schedule — so the carve-out for it is exactly right.

Not verified: I did not fire a second rerun — I took rerequestable as the read-only control, so I have confirmed the predicate rather than reproducing your 403.
