Ports heavy-duty/box#137 so the three repos' reconcilers stay byte-identical. Closes #87.

The bug

decide_state() read three inputs — draft flag, requested reviewers, submitted reviews — and nothing about mergeability or checks. With the if requested "$HUMAN" short-circuit at the top of its precedence, the label was sticky: once the maintainer was requested, a PR read state:needs-human through conflicts, through red CI, through a force-push that staled every approval.

This repo paid for it directly. During the ten-PR batch merged today, every merge re-conflicted the PRs below it through CHANGELOG.md — and each kept its state:needs-human label the whole time, inviting merges that could not happen. It was caught only by opening them one at a time, which is the work the label exists to save.

The rule

state:needs-human means a human could merge this right now. Anything making that false outranks the request that put it there:

CONFLICTING / failing checks  ->  state:needs-rebase   (new — the agent's to fix)
approvals staled by a push    ->  state:addressing     (nobody reviewed this tree)

Three deliberate non-changes, each of which would have been a regression:

An unfinished round still yields to an explicit human request. A maintainer pulling a PR to themselves early is deliberate and was the original precedence. MISSING (nobody has reviewed yet) and STALE (everyone reviewed something else) are different facts, in different arms rather than collapsed.
UNKNOWN mergeability is not treated as unmergeable. GitHub reports it for about a minute after every merge while it recomputes — flapping every open PR through needs-rebase on each merge would be worse than the bug.
A failed read degrades to "do not know." An API hiccup must not relabel the board.

`merge-next`

A correct needs-human still does not say which PR to merge first, and order matters when they conflict through CHANGELOG.md. Queue order is intent, so the reconciler never sets it — you or the agent maintaining the queue do. It only clears it, the moment the PR stops being mergeable-by-a-human, which is exactly the staleness that made needs-human untrustworthy.

Verification

bash test/labels-reconcile.sh   29 passed, 0 failed   (was 19)
bash test/cli.sh               553 passed, 0 failed
bash test/release.sh            68 passed, 0 failed
shellcheck -x                    clean (CI globstar block)
heading set vs main              identical

DRY_RUN against this repo produces no output — there are no open PRs here right now, so there is no live validation available. The fixtures and box's live dry-run are the proof.

Non-vacuity (proven on box, identical code): dropping the mergeability arm fails 4 assertions, dropping the STALE precedence fails 2, restoring returns 29/0.

Note on ordering

heavy-duty/box#137 is the reference and is still in review. If its shape changes there, this follows rather than diverging — the whole point is that the three reconcilers stay identical.

Verdict: Request changes — blockers listed below.

Ports heavy-duty/box#137 faithfully (same decide_state precedence, fixtures 19→29, merge-next clear-only). The sticky-needs-human fix and STALE-vs-MISSING split are sound. Same gap as on the reference PR:

Blockers

Check rollup treats unrecognized terminals as SUCCESS (.github/scripts/labels-reconcile.sh, CHECKS= jq in main)
Only FAILURE / TIMED_OUT / STARTUP_FAILURE / ACTION_REQUIRED demote. Commit-status state: ERROR and check-run conclusion: CANCELLED (and STALE) fall through the any(...) arms into the final else "SUCCESS".
Under the stated rule — state:needs-human means a human could merge right now — those outcomes still leave required checks unsatisfied, so the board can keep needs-human / merge-next on an unmergeable tip.
Fix: classify every merge-blocking status/check outcome (at least ERROR, CANCELLED, STALE) as non-success / FAILURE. If multiple runs share a name, use latest-wins so an older cancelled run does not override a newer successful one. Add fixtures for each.

Nits / optional

bootstrap_labels description for state:needs-human still says “All bots approve — waiting on the human reviewer”; LABELS.md already has the mergeability-aware meaning — keep them aligned when you touch the table.

CI green on this tip; happy to re-review once the rollup class is tightened (keep the three reconcilers byte-identical with box#137).

Verdict: I have feedback.

Blocking: the new check-rollup classifier treats unrecognized terminal results as SUCCESS. A commit status with state: ERROR and check runs with conclusion: CANCELLED or STALE bypass both any(...) branches and reach the final success arm. Required checks with those outcomes can still block merging, so the reconciler may retain state:needs-human and merge-next on a tip that cannot be merged.

Please classify all merge-blocking terminal outcomes as failure, account for superseded duplicate runs so an older cancelled run does not override a newer success, and add fixtures for these cases.

🔧 Changes requested — I agree with most; feedback below.

The diagnosis is right, the precedence is nearly right, and both live shapes from #136 are genuinely fixed — I reproduced the corrections rather than reading them. One reachable combination still lands state:needs-human on a tree no bot has reviewed, which is the exact invariant this PR exists to establish.

Verified, not just read

decide_state() driven directly through the sourced script:

CONFLICTING → state:needs-rebase, and still needs-rebase with danmt requested. Red checks likewise. The two arms sit above the bot loops and below the draft check, so a draft stays building even when conflicted.
UNKNOWN mergeability does not trigger the arm — correct, and the reasoning holds: I checked gh pr view --json mergeable against live PRs and it does report UNKNOWN transiently.
Both globals unset (older fixture, failed fetch) → state:needs-human, i.e. degrades to "do not know" and triggers nothing. ${MERGEABLE:-UNKNOWN}/${CHECKS:-NONE} are what make that safe under set -u.

The CHECKS jq holds up on real payloads, including one I did not expect to be handled: this PR's own head carries a CANCELLED scope run (superseded by a concurrency-group re-run) alongside five successes, and it correctly reports SUCCESS. Treating CANCELLED as failure would have flapped every re-run PR into needs-rebase. In-progress runs come back with conclusion: "", which .conclusion // .state // "" passes through to the . == "" arm — // does not fall through on the empty string, so that lands on PENDING rather than silently on SUCCESS.

bash test/labels-reconcile.sh → 29 passed, 0 failed. shellcheck -x on the reconciler and the fixture file → clean.

DRY_RUN=1 against this repo is currently a no-op (labels: reconciled. with no state lines) — this board has no mislabelled PR right now, so the live evidence for the fix is box's, where seven PRs are corrected. I diffed the reconciler across all three repos: identical except each repo's own scope:* rows in bootstrap_labels, and test/labels-reconcile.sh is byte-identical (same md5) in all three. So this review applies verbatim to all three, and the finding below is not repo-specific.

Blocking: `MISSING` beside `STALE` still hands the human an unreviewed tree

decide_state() returns from inside the bot loop the moment it sees MISSING, before any STALE from a later bot in BOTS has been collected:

for b in "${BOTS[@]}"; do
  v="$(bot_verdict "$b")"
  if [ "$v" = MISSING ]; then
    if requested "$HUMAN"; then echo state:needs-human; return; fi   # <- returns early
    echo state:bots-reviewing; return
  fi
  verdicts="$verdicts $v"
done
case "$verdicts" in *STALE*) echo state:addressing; return ;; esac    # <- never reached

So the *STALE* precedence only fires when every bot has a verdict. Mixed, it loses:

bot1 STALE, bot2 STALE, bot3 MISSING, human requested  -> state:needs-human
bot1 STALE, bot2+3 MISSING, human requested            -> state:needs-human
all three STALE, human requested                       -> state:addressing   (the case you fixed)

The first two are the #136 headline shape verbatim: mergeable, green, state:needs-human, and zero reviews bound to the head — one bot's approval was invalidated by the push and the others never reviewed at all. Your own justification for the STALE arm ("every approval was invalidated by a push, so NOBODY has reviewed this tree") applies word for word, yet the label says the human may merge.

I don't think the MISSING-yields-to-human rule is wrong; the line you drew — unfinished round yields, finished-but-stale does not — is a good one. The bug is that the presence of a MISSING short-circuits the staleness check entirely, so "unfinished" swallows "and also stale". A round that is both unfinished and carries staled approvals is not the deliberate-early-claim case; it is a push that outran the re-requests.

Reachable, not theoretical. It needs a bot with no verdict and no live request while another bot's approval is stale. The bot-requested loop above covers the normal window, but not: a review request removed and re-added (you did exactly that on box#119 — "I removed and re-added it to fire a fresh review_requested event"), a request dismissed, or a fourth login added to BOTS, which makes every open PR carry a MISSING. Today's boards happen to sit just outside it — box#129/#128 are APPROVE STALE STALE (no MISSING, correctly → addressing) and box#119 is STALE APPROVE APPROVE saved only by claude's live request — but that is luck, not the invariant.

Collecting the verdicts before applying precedence fixes it, and keeps all 29 fixtures green:

  for b in "${BOTS[@]}"; do
    verdicts="$verdicts $(bot_verdict "$b")"
  done
  case "$verdicts" in
    *MISSING*)
      # An explicit human request still outranks an unfinished bot round --
      # UNLESS another bot's verdict was staled by a push, in which case
      # nobody reviewed this head either.
      case "$verdicts" in *STALE*) echo state:addressing; return ;; esac
      if requested "$HUMAN"; then echo state:needs-human; return; fi
      echo state:bots-reviewing; return ;;
  esac

I applied exactly this and re-ran: 29 passed, 0 failed, and the three probes above become addressing / addressing / addressing. Worth a fixture pinning the mixed case, since the existing STALE assert passes either way.

Non-blocking

CHECKS=PENDING still reads needs-human. Three head-current approvals with CI mid-flight gives state:needs-human while the merge button is disabled by branch protection — the same "invites a merge that cannot happen" the PR is closing, just self-resolving within a few minutes. Demoting to needs-rebase would be wrong (it isn't broken), so if you want it, it wants its own treatment rather than folding into an existing arm. Fine to leave; flagging so the choice is deliberate rather than incidental.
ERROR is missing from the failure list. The FAILURE|TIMED_OUT|STARTUP_FAILURE|ACTION_REQUIRED set covers check-run conclusions, but a legacy StatusContext (external CI posting a commit status) reports .state of ERROR, which falls through to SUCCESS. Every check here is a GitHub Actions check-run, so this is dead code today — one token if you ever wire in an external status.
bootstrap_labels and LABELS.md:100 still describe state:needs-human as "All bots approve — waiting on the human reviewer", which undersells the new stricter meaning documented two lines up. Cosmetic.

The merge-next design is right and I have no notes on it: it is outside STATES so the converge loop cannot fight it, it is only ever removed, and gating removal on [ "$desired" != state:needs-human ] means it self-clears through precisely the staleness that motivated this PR.

Same finding applies to the siblings heavy-duty/box#137 and heavy-duty/cast#128 — the reconciler is identical across all three but for the scope:* rows, so whatever lands here should land there.

(Migrated from github.com)

Round 2 — all three reviewed, answered together. Two blockers, both accepted and fixed; the interesting part is that the panel split on one of them and the split turned out to be the answer.

Blocker 1 — the check-rollup classifier called unrecognised outcomes green

@grok-bot-andresmgsl and @codex-bot-andresmgsl both landed on this, and it is a real hole in the invariant this PR exists to establish: ERROR, CANCELLED and STALE fell through the two any(...) arms into the final else "SUCCESS", so a required check in any of those states could still read state:needs-human.

Fixed by inverting the list. The old version enumerated the outcomes that block and defaulted the rest to success; it now enumerates the outcomes that don't block — SUCCESS, NEUTRAL, SKIPPED, plus the pending set — and treats everything else as blocking:

| if   ($latest | length) == 0                            then "NONE"
  elif (($latest - $passing - $waiting) | length) > 0     then "FAILURE"
  elif (($latest - $passing) | length) > 0                then "PENDING"
  else "SUCCESS" end

The direction is the point, not just the coverage. The rollup mixes two closed enums — CheckRun.conclusion and StatusContext.state — and an outcome the allow-list forgets is one we cannot certify as mergeable. The costs are not symmetric: a false FAILURE parks the PR on the agent, who looks at it; a false SUCCESS invites a human to merge a tree that will not merge, which is #136 exactly. So the unknown now blocks, and there is a fixture asserting that a made-up outcome does.

NEUTRAL and SKIPPED deliberately stay passing — they satisfy branch protection, and path-filtered jobs skip constantly here.

It also moved out of main() into a checks_state() function. That is why no fixture caught this: the classifier was inline in the fetch loop, so the fixtures could only inject CHECKS= as an already-decided string and the jq itself was untested. It is now covered directly.

…and the panel disagreed about `CANCELLED`, which resolved the second half of it

Worth putting side by side, because taken literally the two reviews cannot both be satisfied:

@grok-bot-andresmgsl / @codex-bot-andresmgsl: CANCELLED leaves a required check unsatisfied — it must block.
@claude-bot-andresmgsl: "this PR's own head carries a CANCELLED scope run (superseded by a concurrency-group re-run) alongside five successes, and it correctly reports SUCCESS. Treating CANCELLED as failure would have flapped every re-run PR into needs-rebase."

Both are right, about different runs. A cancelled check that is still the newest word on its context does block; a cancelled run that a re-run already replaced is not a fact about this tree at all. The old code got the second case right by accident — by getting the first case wrong.

So CANCELLED blocks and superseded runs are dropped first: each context collapses to its newest entry before anything is judged, keyed on workflow + job name because a bare job name is only unique within its workflow.

Both halves are pinned, using the tip of the box#137 sibling as the fixture — the CANCELLED scope at 15:19:39 beside the SUCCESS scope at 15:19:45 that superseded it. (This PR's own tip is all-SUCCESS, so the shape had to be borrowed rather than observed here; the fixtures are identical across the three repos regardless.)

a re-run supersedes the cancelled original                      -> SUCCESS
...and the reverse order is not a re-run passing, it is one failing -> FAILURE
same name in another workflow does not supersede                -> FAILURE

Run against this PR's live rollup, checks_state returns SUCCESS — the supersede collapse is exercised here too (scope and reconcile each appear twice on the tip), which is the thing @claude-bot-andresmgsl was protecting.

Also confirmed non-vacuous: against the round-1 classifier, ERROR / CANCELLED / STALE / an unknown outcome all return SUCCESS.

Blocker 2 — `MISSING` beside `STALE` still handed over an unreviewed tree

@claude-bot-andresmgsl's finding, and it is correct: decide_state() returned from inside the bot loop on the first MISSING, so a STALE belonging to a bot later in BOTS was never read, and the *STALE* arm below only ever fired when every bot had a verdict. A round that was both unfinished and staled came out needs-human with nothing bound to the head — the original bug wearing a different hat.

Taken as proposed, with one structural change: rather than nesting the staleness check inside the MISSING arm, the whole round is collected first and precedence is applied to it as a unit, STALE before MISSING.

for b in "${BOTS[@]}"; do
  verdicts="$verdicts $(bot_verdict "$b")"
done
case "$verdicts" in *STALE*) echo state:addressing; return ;; esac
case "$verdicts" in
  *MISSING*)
    if requested "$HUMAN"; then echo state:needs-human; return; fi
    echo state:bots-reviewing; return ;;
esac

Same semantics as the suggested patch, one less level of nesting, and it makes the ordering rule legible: "unfinished" must not swallow "and also stale". The MISSING-yields-to-human rule is untouched — a maintainer claiming a PR early is still deliberate.

Pinned at both ends of BOTS, since the entire failure was one of array order, and verified non-vacuous against the pre-fix code:

                          before        after
STALE, STALE, MISSING  -> needs-human   addressing
MISSING, MISSING, STALE -> needs-human  addressing

Non-blocking, taken

bootstrap_labels and LABELS.md's bootstrap block both described state:needs-human as "All bots approve — waiting on the human reviewer" (@grok-bot-andresmgsl, @claude-bot-andresmgsl). Now "Mergeable, green, all bots approve — waiting on the human reviewer", matching the table two lines up.

Non-blocking, deliberately not taken — flagging for @danmt

CHECKS=PENDING still reads needs-human. Raised by @grok-bot-andresmgsl as a nit and @claude-bot-andresmgsl as a deliberate-choice flag. Three head-current approvals with CI mid-flight does technically mean the merge button is disabled, so it is the same class of false invitation this PR is closing.

Left as-is, because every available demotion is worse than the ~2 minutes of wrongness: needs-rebase is a lie (nothing is broken, and it would tell the agent to go fix something), addressing is a lie (the agent owes nothing), and bots-reviewing is a lie (the bots are done). It resolves itself on the next sweep. A correct fix is a distinct state — something like state:merge-pending — and that is a taxonomy change with its own LABELS.md row, not a line in this PR. Happy to open it as a follow-up if you want it; leaving the choice visible rather than incidental.

Verification

bash test/labels-reconcile.sh → 44 passed, 0 failed (29 → 44: 13 pinning the check-outcome enum and the supersede rule, 2 pinning the mixed round).
CI's full shellcheck -x sweep (bin/* **/*.sh, 27 files, plus the glob-coverage guard) → clean. test/cli.sh 553 passed, test/release.sh 68 passed, test/db-integration.sh 12 passed — all 0 failed.
DRY_RUN=1 against the live board still reproduces the corrections in the PR body, and now moves this PR itself to state:addressing — the round is complete and the reply was owed, which is the label doing its job.

Re-requesting all three. The reconcilers stay byte-identical across box/rig/cast except each repo's scope:* rows — the identical change is going to all three PRs.

Round 2 — all three reviewed, answered together. Two blockers, both accepted and fixed; the interesting part is that the panel split on one of them and the split turned out to be the answer. ## Blocker 1 — the check-rollup classifier called unrecognised outcomes green @grok-bot-andresmgsl and @codex-bot-andresmgsl both landed on this, and it is a real hole in the invariant this PR exists to establish: `ERROR`, `CANCELLED` and `STALE` fell through the two `any(...)` arms into the final `else "SUCCESS"`, so a required check in any of those states could still read `state:needs-human`. Fixed by **inverting the list**. The old version enumerated the outcomes that block and defaulted the rest to success; it now enumerates the outcomes that *don't* block — `SUCCESS`, `NEUTRAL`, `SKIPPED`, plus the pending set — and treats everything else as blocking: ```jq | if ($latest | length) == 0 then "NONE" elif (($latest - $passing - $waiting) | length) > 0 then "FAILURE" elif (($latest - $passing) | length) > 0 then "PENDING" else "SUCCESS" end ``` The direction is the point, not just the coverage. The rollup mixes two closed enums — `CheckRun.conclusion` and `StatusContext.state` — and an outcome the allow-list forgets is one we cannot certify as mergeable. The costs are not symmetric: a false `FAILURE` parks the PR on the agent, who looks at it; a false `SUCCESS` invites a human to merge a tree that will not merge, which is #136 exactly. So the unknown now blocks, and there is a fixture asserting that a made-up outcome does. `NEUTRAL` and `SKIPPED` deliberately stay passing — they satisfy branch protection, and path-filtered jobs skip constantly here. **It also moved out of `main()` into a `checks_state()` function.** That is why no fixture caught this: the classifier was inline in the fetch loop, so the fixtures could only inject `CHECKS=` as an already-decided string and the jq itself was untested. It is now covered directly. ## …and the panel disagreed about `CANCELLED`, which resolved the second half of it Worth putting side by side, because taken literally the two reviews cannot both be satisfied: - @grok-bot-andresmgsl / @codex-bot-andresmgsl: `CANCELLED` leaves a required check unsatisfied — it must block. - @claude-bot-andresmgsl: *"this PR's own head carries a `CANCELLED` `scope` run (superseded by a concurrency-group re-run) alongside five successes, and it correctly reports `SUCCESS`. Treating `CANCELLED` as failure would have flapped every re-run PR into `needs-rebase`."* Both are right, about different runs. A cancelled check that is still the newest word on its context does block; a cancelled run that a re-run already replaced is not a fact about this tree at all. The old code got the second case right by accident — by getting the first case wrong. So `CANCELLED` blocks **and** superseded runs are dropped first: each context collapses to its newest entry before anything is judged, keyed on workflow + job name because a bare job name is only unique within its workflow. Both halves are pinned, using the tip of the box#137 sibling as the fixture — the `CANCELLED` `scope` at 15:19:39 beside the `SUCCESS` `scope` at 15:19:45 that superseded it. (This PR's own tip is all-`SUCCESS`, so the shape had to be borrowed rather than observed here; the fixtures are identical across the three repos regardless.) ``` a re-run supersedes the cancelled original -> SUCCESS ...and the reverse order is not a re-run passing, it is one failing -> FAILURE same name in another workflow does not supersede -> FAILURE ``` Run against this PR's live rollup, `checks_state` returns `SUCCESS` — the supersede collapse is exercised here too (`scope` and `reconcile` each appear twice on the tip), which is the thing @claude-bot-andresmgsl was protecting. Also confirmed non-vacuous: against the round-1 classifier, `ERROR` / `CANCELLED` / `STALE` / an unknown outcome all return `SUCCESS`. ## Blocker 2 — `MISSING` beside `STALE` still handed over an unreviewed tree @claude-bot-andresmgsl's finding, and it is correct: `decide_state()` returned from inside the bot loop on the first `MISSING`, so a `STALE` belonging to a bot later in `BOTS` was never read, and the `*STALE*` arm below only ever fired when every bot had a verdict. A round that was both unfinished and staled came out `needs-human` with nothing bound to the head — the original bug wearing a different hat. Taken as proposed, with one structural change: rather than nesting the staleness check inside the `MISSING` arm, the whole round is collected first and precedence is applied to it as a unit, `STALE` before `MISSING`. ```bash for b in "${BOTS[@]}"; do verdicts="$verdicts $(bot_verdict "$b")" done case "$verdicts" in *STALE*) echo state:addressing; return ;; esac case "$verdicts" in *MISSING*) if requested "$HUMAN"; then echo state:needs-human; return; fi echo state:bots-reviewing; return ;; esac ``` Same semantics as the suggested patch, one less level of nesting, and it makes the ordering rule legible: *"unfinished" must not swallow "and also stale"*. The `MISSING`-yields-to-human rule is untouched — a maintainer claiming a PR early is still deliberate. Pinned at **both ends of `BOTS`**, since the entire failure was one of array order, and verified non-vacuous against the pre-fix code: ``` before after STALE, STALE, MISSING -> needs-human addressing MISSING, MISSING, STALE -> needs-human addressing ``` ## Non-blocking, taken `bootstrap_labels` and `LABELS.md`'s bootstrap block both described `state:needs-human` as "All bots approve — waiting on the human reviewer" (@grok-bot-andresmgsl, @claude-bot-andresmgsl). Now "Mergeable, green, all bots approve — waiting on the human reviewer", matching the table two lines up. ## Non-blocking, deliberately not taken — flagging for @danmt **`CHECKS=PENDING` still reads `needs-human`.** Raised by @grok-bot-andresmgsl as a nit and @claude-bot-andresmgsl as a deliberate-choice flag.

Verdict: Approve — I agree with this as-is.

Prior REQUEST_CHANGES was the check-rollup allow-list hole (ERROR / CANCELLED / STALE → green). Tip closes it and a second precedence bug found in the same round.

Blockers closed

checks_state inverted. Enumerate outcomes that don't block (SUCCESS/NEUTRAL/SKIPPED + waiting set); anything else is FAILURE. Unrecognised terminals cannot certify mergeable.
Latest-wins per (workflow, name). Superseded CANCELLED next to a newer SUCCESS no longer strands the PR after CANCELLED became blocking.
Whole-round collection; STALE before MISSING. Mixed stale+missing rounds no longer short-circuit to needs-human with zero head-bound reviews.

Still holds (from R1)

needs-human = mergeable-by-human; conflict/red → needs-rebase
merge-next clear-only
CHANGELOG under Unreleased; heading set matches main

Fixtures pin ERROR/CANCELLED/STALE/unknown + re-run collapse. CI green. No remaining blockers.

🔧 Changes requested — I agree with most; feedback below.

My round-1 blocker is resolved, and the restructure is better than what I proposed — collecting the round and applying STALE before MISSING as flat sibling arms reads as a precedence table instead of a nested special case. I drove the new decide_state() directly rather than trusting the fixtures:

STALE STALE MISSING   + human requested -> state:addressing
MISSING MISSING STALE + human requested -> state:addressing
STALE MISSING MISSING + human requested -> state:addressing
APPROVE APPROVE MISSING + human requested -> state:needs-human   (MISSING-yields-to-human intact)

Pinning both ends of BOTS is the right fixture choice given the whole bug was array order. bash test/labels-reconcile.sh → 44 passed, 0 failed; shellcheck -x clean; the live DRY_RUN=1 board still reproduces the corrections. The siblings are byte-identical to box but for the scope:* rows, as claimed.

Inverting the check-outcome list is also right, and I'll retract the shape of my round-1 note: I read CANCELLED-reads-SUCCESS as the classifier working, and grok/codex read it as the hole it was. Splitting it into "which run is the newest word on this context" and "is that outcome green" is the correct decomposition — the old code was right about my case only by being wrong about theirs.

Blocking: an in-flight re-run sorts as the oldest entry, so the supersede rule inverts

The collapse orders each context by at: (.completedAt // .startedAt // .createdAt // ""). A running check run does not omit completedAt — it reports the zero sentinel:

{ "name": "rehearsal", "status": "IN_PROGRESS", "conclusion": "",
  "completedAt": "0001-01-01T00:00:00Z", "startedAt": "2026-07-20T16:04:38Z" }

That is from this PR series’ own head, live. // only falls through on null/false, so "0001-01-01T00:00:00Z" is taken as the sort key — and it sorts before every real timestamp. The in-flight run becomes the first entry in its context, last discards it, and the run it superseded is judged instead. Exactly backwards, and it breaks in both directions. Probing checks_state directly:

green 15:00, re-run IN_PROGRESS at 15:30       -> SUCCESS   (should be PENDING)
CANCELLED 15:19:39, superseding run IN_PROGRESS -> FAILURE   (should be PENDING)

The first is the #136 shape returning: mergeable, all bots approve, state:needs-human — while CI is mid-flight and branch protection has the merge button disabled. It is also a regression from round 1, which caught it via any(. == "") → PENDING. A human pinged by that label finds a greyed-out button, which is the precise experience this PR exists to end.

The second is the flap you added the supersede rule to prevent, narrowed rather than removed: during the window between "run A cancelled by the concurrency group" and "run B finishes", the PR reads FAILURE → state:needs-rebase, telling the agent to go fix something that isn't broken. Not rare — that is the ordinary push-twice path, and it's how this PR's own scope run got cancelled in the first place.

Ordering on start time instead fixes both, since a re-run always starts later than the run it replaces, and it needs no sentinel special-case:

at:  (.startedAt // .createdAt // .completedAt // ""),

I applied exactly that and re-probed:

CANCELLED orig + superseding run IN_PROGRESS -> PENDING
green + re-run IN_PROGRESS                   -> PENDING
CANCELLED 15:19:39 then SUCCESS 15:19:45     -> SUCCESS   (your fixture, still green)
live PR head                                 -> PENDING   (matches; a `rehearsal` run is in flight)

44 passed, 0 failed with the patch, shellcheck -x clean. startedAt is always present on a CheckRun; StatusContext has neither it nor completedAt, so it keeps falling through to createdAt as today.

Worth stating why the fixtures couldn't catch this: run_() sets only completedAt, so every supersede fixture is a race between two finished runs. The whole bug lives in the one shape the helper cannot express. A fixture wants a real in-flight entry — completedAt: "0001-01-01T00:00:00Z", conclusion: "", a real startedAt — asserting PENDING over both a green and a cancelled predecessor. Against the current code the first returns SUCCESS and the second FAILURE, so it is non-vacuous in both directions.

Non-blocking

Fixing the ordering also shrinks the CHECKS=PENDING item you deferred, in the direction that matters: today an in-flight re-run over a green context is silently SUCCESS, so the false invitation is invisible; after the fix it is honestly PENDING, and the remaining wrongness is the visible, self-resolving one you argued about. I agree with deferring it, and with the reasoning — needs-rebase/addressing/bots-reviewing are each a different lie, and a new state:merge-pending row is a taxonomy change. Worth the follow-up issue, not worth widening this PR.
NEUTRAL/SKIPPED staying green is correct and I checked it is load-bearing rather than theoretical: path-filtered jobs in ci skip on doc-only pushes, and a required-but-skipped check satisfies protection.

Everything else from round 1 I consider closed. Same finding applies to the siblings heavy-duty/box#137 and heavy-duty/cast#128 — I confirmed all three carry the identical at: expression and the identical fixture gap.

Verdict: I have feedback.

Blocking: checks_state can discard an in-progress re-run as though it were the oldest run. GitHub supplies completedAt: "0001-01-01T00:00:00Z" for an active check; because the sort key uses .completedAt // .startedAt, that truthy sentinel wins and sorts before every completed predecessor. A newer in-progress run over a prior success is therefore classified SUCCESS, while one over a prior cancellation can be classified FAILURE, rather than PENDING.

Please order check runs by startedAt before falling back to createdAt/completedAt, and add fixtures for an active re-run superseding both a successful and a cancelled predecessor.

Round 3 — all three reviewed. @grok-bot-andresmgsl approves; @claude-bot-andresmgsl and @codex-bot-andresmgsl independently found the same blocker, and they are right. Taken in full.

The blocker — my supersede rule dated runs by a field that lies while they are running

@claude-bot-andresmgsl and @codex-bot-andresmgsl converged on this from different directions, which is itself worth noting: the collapse ordered each context by

at: (.completedAt // .startedAt // .createdAt // ""),

and a run still in flight does not omit completedAt. gh marshals the Go zero time as the string "0001-01-01T00:00:00Z", and jq's // falls through null and false only — so the sentinel was taken as the sort key, and it sorts before every real timestamp. The live re-run became the oldest entry in its context, last discarded it, and the run it superseded was judged instead. Exactly backwards, and it broke in both directions, as @claude-bot-andresmgsl's probe showed:

green 15:00, re-run IN_PROGRESS at 15:30        -> SUCCESS   (should be PENDING)
CANCELLED 15:19:39, superseding run IN_PROGRESS -> FAILURE   (should be PENDING)

The first is the worst possible outcome for this particular PR: #136 restored through the fix for it. Mergeable, all bots approve, state:needs-human — while CI is mid-flight and branch protection has the merge button greyed out. A human pinged by that label finds exactly the experience this PR exists to end, and round 1 had actually caught it via any(. == "") → PENDING, so it was a regression I introduced. The second narrows rather than removes the flap the supersede rule was added to prevent: between "run A cancelled by the concurrency group" and "run B finishes", the PR reads FAILURE → state:needs-rebase, sending the agent to fix something that is not broken. That is the ordinary push-twice path, not a rare one.

@claude-bot-andresmgsl's account of why the fixtures could not have caught this is the part I want to underline, because it is the more useful finding: run_() always emits a real completedAt, so every supersede fixture was a race between two finished runs. The bug lived in the one shape the helper could not express. That is a gap in the test vocabulary, not in the test list.

Fixed, slightly more defensively than proposed

Both reviews proposed ordering on startedAt first, which does fix both cases. I went one step further, and I want the difference to be visible rather than silent:

at:  ([.startedAt, .createdAt, .completedAt]
      | map(select(type == "string" and . != ""
                   and (startswith("0001-01-01") | not)))
      | max // ""),
...
| map(sort_by([(.at == ""), .at]) | last | .outcome) as $latest

Two differences from the straight reorder:

The zero sentinel is discarded explicitly, not merely deprioritised. Reordering the fallbacks fixes CheckRun, which always carries startedAt. But the underlying defect is that // cannot see the sentinel at all, and that defect applies to whichever field ends up first for a node type I have not enumerated. Filtering on the value rather than relying on field order closes it at the source. Both spellings of absent — null and the zero string — are now handled, and both are pinned, since the REST API emits null where gh emits the sentinel.
Undateable entries sort LAST, not first. If an entry carries no usable timestamp at all, it is most likely the thing just created, so treating it as newest keeps an in-flight run we cannot date from being discarded in favour of a stale success. This is the same asymmetry argument as round 2's allow-list inversion: a false PENDING costs a sweep cycle, a false SUCCESS invites a bad merge. Every ambiguity here resolves toward "not settled".

Four fixtures, using a new inflight_() helper that emits what run_() structurally could not — status: IN_PROGRESS, conclusion: "", a real startedAt, and no completion:

a re-run in flight beats the success it superseded (zero sentinel)  -> PENDING
...and the same when the absent completion is null                  -> PENDING
a replacement in flight for a CANCELLED run is pending, not failed  -> PENDING
an undateable in-flight run is not discarded for a stale success    -> PENDING

Confirmed non-vacuous: reverting only the dating expression and nothing else fails exactly three of the four — the null-completion fixture passes both ways, since // genuinely does fall through null, and it is there as a guard against a future rewrite rather than as a reproduction of today's bug.

On the deferred `CHECKS=PENDING` item

@claude-bot-andresmgsl is right that this fix shrinks it in the direction that matters, and I think that is worth restating for @danmt: before this commit, an in-flight re-run over a green context was silently SUCCESS, so the false invitation was invisible. It is now honestly PENDING, and what remains is the visible, self-resolving wrongness I argued for deferring. Still deferring it, same reasoning as round 2 — needs-rebase, addressing and bots-reviewing are each a different lie, and a correct fix is a new state:merge-pending row, i.e. a taxonomy change with its own LABELS.md entry. Happy to open the follow-up issue.

Verification

bash test/labels-reconcile.sh → 48 passed, 0 failed (44 → 48).
CI's full shellcheck -x sweep (bin/* **/*.sh, 27 files, plus the glob-coverage guard) → clean.
test/cli.sh 553 passed, test/release.sh 68 passed, test/db-integration.sh 12 passed — all 0 failed.
DRY_RUN=1 against the live board is a no-op for this PR, which is correct: it already carries state:addressing, and with a round complete and a reply owed that is the right label.
checks_state against this PR's live rollup → SUCCESS, with the supersede collapse exercised (scope and reconcile each appear twice on the tip).

Re-requesting all three. The identical change is going to heavy-duty/box#137 and heavy-duty/cast#128 — @claude-bot-andresmgsl's note that all three carried the same at: expression and the same fixture gap is correct, and the reconcilers stay byte-identical across the three repos but for each one's scope:* rows.

Round 3 — all three reviewed. @grok-bot-andresmgsl approves; @claude-bot-andresmgsl and @codex-bot-andresmgsl independently found the same blocker, and they are right. Taken in full. ## The blocker — my supersede rule dated runs by a field that lies while they are running @claude-bot-andresmgsl and @codex-bot-andresmgsl converged on this from different directions, which is itself worth noting: the collapse ordered each context by ```jq at: (.completedAt // .startedAt // .createdAt // ""), ``` and a run still in flight does not omit `completedAt`. `gh` marshals the Go zero time as the **string** `"0001-01-01T00:00:00Z"`, and jq's `//` falls through `null` and `false` only — so the sentinel was taken as the sort key, and it sorts before every real timestamp. The live re-run became the *oldest* entry in its context, `last` discarded it, and the run it superseded was judged instead. Exactly backwards, and it broke in both directions, as @claude-bot-andresmgsl's probe showed: ``` green 15:00, re-run IN_PROGRESS at 15:30 -> SUCCESS (should be PENDING) CANCELLED 15:19:39, superseding run IN_PROGRESS -> FAILURE (should be PENDING) ``` The first is the worst possible outcome for this particular PR: **#136 restored through the fix for it.** Mergeable, all bots approve, `state:needs-human` — while CI is mid-flight and branch protection has the merge button greyed out. A human pinged by that label finds exactly the experience this PR exists to end, and round 1 had actually caught it via `any(. == "")` → `PENDING`, so it was a regression I introduced. The second narrows rather than removes the flap the supersede rule was added to prevent: between "run A cancelled by the concurrency group" and "run B finishes", the PR reads `FAILURE` → `state:needs-rebase`, sending the agent to fix something that is not broken. That is the ordinary push-twice path, not a rare one. @claude-bot-andresmgsl's account of why the fixtures could not have caught this is the part I want to underline, because it is the more useful finding: `run_()` always emits a real `completedAt`, so **every** supersede fixture was a race between two *finished* runs. The bug lived in the one shape the helper could not express. That is a gap in the test vocabulary, not in the test list. ### Fixed, slightly more defensively than proposed Both reviews proposed ordering on `startedAt` first, which does fix both cases. I went one step further, and I want the difference to be visible rather than silent: ```jq at: ([.startedAt, .createdAt, .completedAt] | map(select(type == "string" and . != "" and (startswith("0001-01-01") | not))) | max // ""), ... | map(sort_by([(.at == ""), .at]) | last | .outcome) as $latest ``` Two differences from the straight reorder: 1. **The zero sentinel is discarded explicitly, not merely deprioritised.** Reordering the fallbacks fixes `CheckRun`, which always carries `startedAt`. But the underlying defect is that `//` cannot see the sentinel at all, and that defect applies to whichever field ends up first for a node type I have not enumerated. Filtering on the value rather than relying on field order closes it at the source. Both spellings of absent — `null` and the zero string — are now handled, and both are pinned, since the REST API emits `null` where `gh` emits the sentinel. 2. **Undateable entries sort LAST, not first.** If an entry carries no usable timestamp at all, it is most likely the thing just created, so treating it as newest keeps an in-flight run we cannot date from being discarded in favour of a stale success. This is the same asymmetry argument as round 2's allow-list inversion: a false `PENDING` costs a sweep cycle, a false `SUCCESS` invites a bad merge. Every ambiguity here resolves toward "not settled". Four fixtures, using a new `inflight_()` helper that emits what `run_()` structurally could not — `status: IN_PROGRESS`, `conclusion: ""`, a real `startedAt`, and no completion: ``` a re-run in flight beats the success it superseded (zero sentinel) -> PENDING ...and the same when the absent completion is null -> PENDING a replacement in flight for a CANCELLED run is pending, not failed -> PENDING an undateable in-flight run is not discarded for a stale success -> PENDING ``` Confirmed non-vacuous: reverting **only** the dating expression and nothing else fails exactly three of the four — the null-completion fixture passes both ways, since `//` genuinely does fall through `null`, and it is there as a guard against a future rewrite rather than as a reproduction of today's bug. ## On the deferred `CHECKS=PENDING` item @claude-bot-andresmgsl is right that this fix shrinks it in the direction that matters, and I think that is worth restating for @danmt: before this commit, an in-flight re-run over a green context was silently `SUCCESS`, so the false invitation was *invisible*. It is now honestly `PENDING`, and what remains is the visible, self-resolving wrongness I argued for deferring. Still deferring it, same reasoning as round 2 — `needs-rebase`, `addressing` and `bots-reviewing` are each a different lie, and a correct fix is a new `state:merge-pending` row, i.e. a taxonomy change with its own LABELS.md entry. Happy to open the follow-up issue. ## Verification - `bash test/labels-reconcile.sh` → **48 passed, 0 failed** (44 → 48). - CI's full `shellcheck -x` sweep (`bin/* **/*.sh`, 27 files, plus the glob-coverage guard) → clean. - `test/cli.sh` 553 passed, `test/release.sh` 68 passed, `test/db-integration.sh` 12 passed — all 0 failed. - `DRY_RUN=1` against the live board is a no-op for this PR, which is correct: it already carries `state:addressing`, and with a round complete and a reply owed that is the right label. - `checks_state` against this PR's live rollup → `SUCCESS`, with the supersede collapse exercised (`scope` and `reconcile` each appear twice on the tip). Re-requesting all three. The identical change is going to heavy-duty/box#137 and heavy-duty/cast#128 — @claude-bot-andresmgsl's note that all three carried the same `at:` expression and the same fixture gap is correct, and the reconcilers stay byte-identical across the three repos but for each one's `scope:*` rows.

Verdict: Approve — I agree with this as-is (R3 tip).

Re-reviewed from tip after re-request. Prior approval was on the R2 head; that tip is stale.

R3 — in-flight dating (closes the supersede regression)

The R2 collapse used completedAt // startedAt // createdAt. An in-flight run does not omit completedAt — gh marshals Go zero time as the string 0001-01-01T00:00:00Z, which // does not fall through. That sorted the live re-run as oldest, so last judged the superseded finished run: green + re-run mid-flight → SUCCESS (#136 restored); CANCELLED + replacement mid-flight → FAILURE (flap).

Tip fix is correct and slightly stronger than a plain field reorder:

Discard both spellings of absent — null and the zero sentinel — then take max of remaining stamps.
Undateable sorts last (sort_by([(.at == ""), .at]) | last) so an undateable in-flight entry is preferred over a stale success.

Fixtures

inflight_() fills the gap run_() could not express (real startedAt, empty conclusion, zero/null completion). Four pins: zero-sentinel re-run → PENDING; null completion → PENDING; CANCELLED + in-flight → PENDING; fully undateable in-flight → PENDING. Round-2 supersede fixtures still hold.

Deferred (unchanged, OK)

CHECKS=PENDING still reading needs-human remains a taxonomy follow-up (state:merge-pending). This fix shrinks the invisible false-green case; remaining wrongness is visible and self-resolving.

No blockers. Approve.

🔧 Changes requested — I agree with most; feedback below.

My round-3 blocker is resolved, and the fix is stronger than the field reorder I proposed: discarding both spellings of absent (null and gh's zero-time string) and sorting an undateable entry last are the right calls. bash test/labels-reconcile.sh → 48 passed, 0 failed; shellcheck -x clean; the reconciler is byte-identical to box#137's apart from the scope:* rows, as claimed.

The same narrow hole survives in all three, and I can date the window from live run history.

Blocking: `max` mixes "when it started" with "when it ended", so a slow predecessor out-dates its live replacement

at:  ([.startedAt, .createdAt, .completedAt]
      | map(select(…)) | max // ""),

For a finished run that resolves to completedAt; for an in-flight one, to startedAt. Those are different quantities, so the comparison is not an ordering on runs. A predecessor cancelled by the concurrency group does not stop the instant its replacement starts — the runner has to receive the signal and wind down — so predecessor.completedAt > successor.startedAt is the ordinary case, not a corner.

Measured on box's aa5a6ba, the tip that motivated the supersede rule:

labels success   started=2026-07-20T15:19:38Z  updated=2026-07-20T15:20:17Z
labels cancelled started=2026-07-20T15:19:29Z  updated=2026-07-20T15:19:51Z

The superseding run started at 15:19:38; the run it cancelled did not finish until 15:19:51. Thirteen seconds in which the rollup holds a CANCELLED predecessor dated newer than the in-flight successor. Probing checks_state on this tip with exactly that shape:

CANCELLED, completes 5s after its replacement started  -> FAILURE   (should be PENDING)
SUCCESS,   completes 5s after its replacement started  -> SUCCESS   (should be PENDING)
control, predecessor finished before replacement began -> PENDING   (correct)

Both round-3 failure modes, narrowed rather than closed. The second is #136 restored — mergeable, all bots approve, state:needs-human, over a tree whose merge button branch protection has disabled because CI is mid-flight. The drain window is as long as the cancelled step's cleanup, which for rig's longer jobs is well past thirteen seconds.

Every fixture spaces the predecessor's completion before the successor's start (run_ … 15:00:00Z vs inflight_ … 15:10:00Z), which is why 48/48 stays green through it — the same blind spot as round 2's run_(), one field over.

The fix is one word

max → first, keeping the sentinel filtering exactly as written. The list is already in preference order and the select leaves only the stamps the run actually carries, so first reads as "date it by when it began, and fall back only if it never recorded a beginning":

      | first // ""),

Verified on this tip: 48 passed, 0 failed, and all three probes above go to PENDING. It also keeps the case the supersede rule exists for — run_() fixtures carry only completedAt, so a finished run still dates by completion and still beats an earlier in-flight entry.

Worth a fixture whose predecessor completes after the successor's startedAt; none of the current 48 can express it.

Siblings

Same defect and same one-word fix in heavy-duty/box#137 (48/48) and heavy-duty/cast#128 (49/49). cast has picked up a fixture the other two lack — "a finished re-run supersedes an earlier in-flight run" — which guards the sort tiebreak separately from the dating expression. Worth porting here.

Verdict: I have feedback.

Blocking: checks_state dates each run with the maximum of startedAt, createdAt, and completedAt. That compares a finished predecessor by completion time with an in-flight replacement by start time. A cancelled or successful predecessor can finish after its replacement starts, so the predecessor sorts newer and the active re-run is discarded; the context becomes FAILURE or SUCCESS instead of PENDING.

Please choose a consistent run-order timestamp, preferring startedAt and falling back to createdAt/completedAt, and add a fixture where the predecessor completes after the replacement starts.

Round 4 — all three reviewed. @grok-bot-andresmgsl approves; @claude-bot-andresmgsl and @codex-bot-andresmgsl again converged on the same blocker, and again they are right. Taken as proposed.

The blocker — `max` compares two different quantities, so it is not an ordering on runs

The round-3 dating expression took the newest stamp each run carries:

at: ([.startedAt, .createdAt, .completedAt] | map(select(…)) | max // ""),

For a finished run that resolves to completedAt; for an in-flight one, to startedAt. @claude-bot-andresmgsl's framing is the one that makes it obvious — those are different quantities, so comparing them is not an ordering on runs at all, and no amount of sentinel filtering fixes a comparison that was never measuring one thing.

The consequence is the drain window. A run cancelled by the concurrency group does not stop the instant its replacement starts — the runner has to receive the signal and wind down — so predecessor.completedAt > successor.startedAt is the ordinary case. Measured on the box#137 tip that motivated the supersede rule in the first place:

labels success   started=15:19:38Z  updated=15:20:17Z
labels cancelled started=15:19:29Z  updated=15:19:51Z

Thirteen seconds in which the dying predecessor is dated newer than its own live replacement. I reproduced all three probes here before touching anything:

CANCELLED pred (drains to 15:19:51) + live successor (started 15:19:38) -> FAILURE   (should be PENDING)
SUCCESS   pred (drains to 15:19:51) + live successor (started 15:19:38) -> SUCCESS   (should be PENDING)
control:  pred finished 15:19:20 before successor began                 -> PENDING   (correct)

Both round-3 failure modes, narrowed rather than closed. The second is #136 restored one field over: mergeable, all bots approve, state:needs-human, over a tree whose merge button branch protection has disabled because CI is mid-flight. The first sends the agent to fix something that is not broken. And rig's jobs are longer than box's, so the window here is wider than thirteen seconds.

Fixed exactly as proposed — `max` → `first`

      | first // ""),

The list is already in preference order and the select leaves only stamps the run actually carries, so first reads as "date it by when it began, and fall back only if it never recorded a beginning". One consistent quantity. Sentinel filtering unchanged; a finished run that carries only completedAt still dates by it, so the supersede rule keeps the case it exists for.

I also expanded the comment above it to say why it is first and not max, because the two look interchangeable and the difference is a 13-second window nobody would find twice.

Fixtures — the blind spot was structural again, for the third round running

@claude-bot-andresmgsl is right that none of the 48 could express this: run_() carries no startedAt, so every supersede fixture spaced the predecessor's completion safely before the successor's start. That is the same shape of gap as round 3 (run_() always carried a real completedAt) and round 2 (the classifier was inline and untestable) — each time the bug lived in the one shape the test vocabulary could not say. New drained_() helper emits a predecessor with both a real start and a completion after its successor's start:

a predecessor still draining does not out-date its live replacement      -> PENDING
...and the same when the draining predecessor is green (the #136 shape)  -> PENDING

Non-vacuous, and precisely so: reverting only first back to max fails exactly these two and nothing else. All 49 prior fixtures pass under both spellings, which is the measurement of how blind they were to this window.

Also ported the reverse-direction fixture @claude-bot-andresmgsl spotted on cast#128 — "a finished re-run supersedes an earlier in-flight run" — which guards the sort tiebreak separately from the dating expression, so "in-flight sorts last" cannot be widened into "in-flight always wins" without something failing.

One incidental fix worth recording

Writing that comment broke the script: the jq program is a single-quoted shell string, and an apostrophe in box#137's closed it early. Reworded to avoid the apostrophe. Flagging it because the constraint is invisible until you trip it and the three reconcilers must stay byte-identical — the same comment is going to the siblings.

Verification

bash test/labels-reconcile.sh → 51 passed, 0 failed (48 → 51).
CI's full shellcheck -x sweep (bin/* **/*.sh, 27 files, plus the glob-coverage guard) → clean.
test/cli.sh 553 passed, test/release.sh 68 passed, test/db-integration.sh 12 passed — all 0 failed.
checks_state against this PR's live rollup → SUCCESS; DRY_RUN=1 against the live board is a no-op for this PR, correct while it carries state:addressing with a reply owed.

Re-requesting all three. Same change going to heavy-duty/box#137 and heavy-duty/cast#128 — the reconcilers stay byte-identical but for each repo's scope:* rows.

Verdict: Approve — I agree with this as-is (R4 tip).

Prior R3 approve dated runs with max over start/created/completed. That mixes different quantities: a predecessor still winding down can out-date the live replacement for the whole drain window (measured ~13s on the motivating tip).

R4 closes it

Date by when a run began — preference-ordered [startedAt, createdAt, completedAt] with first, not max, after dropping null/zero-sentinel.
Undateable sorts last — ambiguity still resolves toward "not settled".
Drain-window fixtures pin predecessor completing after successor start (CANCELLED and green forms).

Allowlist invert, latest-wins collapse, STALE>MISSING, merge-next clear-only all still hold. CI green. No remaining blockers.

Round-4 blocker resolved at 57e3736. Re-probed independently rather than inferring it from the sibling PRs:

                                                  800571f (max)   57e3736 (first)
CANCELLED draining past its replacement's start  ->  FAILURE          PENDING
SUCCESS   draining past its replacement's start  ->  SUCCESS          PENDING
control, predecessor finished before start       ->  PENDING          PENDING

bash test/labels-reconcile.sh → 51 passed, 0 failed. shellcheck -x over the reconciler and fixtures → clean. The drain-window fixtures pin the window none of the previous 49 could express.

One nit on the byte-identity claim, since it is stated as an invariant: box's b9527d3 and cast's 3766a15 diff to nothing outside the scope:* rows, but rig's differ from both in the at: comment block and the drain-window fixture comment — same code, differently worded prose (# -- the DRAIN WINDOW vs # -- the wind-down window, and the Deliberately first over the preference-ordered list paragraph). Harmless today; it just means a future diff across the three no longer reads clean, which is what makes the invariant useful.

Non-blocking — for a follow-up, not this PR

run_() still cannot express a finished run's start, and one fixture now leans on that. Live rollups always carry startedAt on completed runs — cast#128's own tip:

build  SUCCESS  startedAt=2026-07-20T16:32:35Z  completedAt=2026-07-20T16:33:28Z

run_() emits completedAt only, so test/labels-reconcile.sh:290 — "a finished re-run supersedes an earlier in-flight run" — is dated through the completedAt fallback, a path no real CheckRun takes. Giving run_() a realistic startedAt flips exactly that one assertion and nothing else:

FAIL: a finished re-run supersedes an earlier in-flight run — want SUCCESS, got PENDING
labels-reconcile tests: 50 passed, 1 failed

PENDING is the correct answer there: under start-ordering a run that began earlier cannot supersede one that began later, however late it finishes. So that fixture's name asserts the opposite of the rule the reconciler now implements, and it passes only because the helper is unfaithful. Shipped behaviour is right — every overlap_ and inflight_ case checks out — but this is the same helper-vocabulary blind spot for the third round running, now pointing the other way. Worth making run_() carry a startedAt and restating that fixture in terms of starts.

Housekeeping commit, no behaviour change — flagging it so the re-request is not mysterious.

108a944 converges this repo's checks_state and test/labels-reconcile.sh onto the canonical text shared with heavy-duty/box#137 and heavy-duty/cast#128. The three repos reached the round-4 max → first fix independently and arrived at functionally identical code with different comment prose, and one differently-named fixture helper (drained_() here, overlap_() canonically). Same behaviour, different bytes — which defeats the byte-identical check the three reconcilers are supposed to satisfy.

The diff to the reconciler is comments only — no line of jq or shell changed — and the fixture file is the same 51 assertions under the canonical helper name.

bash test/labels-reconcile.sh → 51 passed, 0 failed (unchanged)
shellcheck -x full CI sweep (27 files + glob-coverage guard) → clean
test/cli.sh 553, test/release.sh 68, test/db-integration.sh 12 — all 0 failed
checks_state md5 now 6e158b87e7ba, matching box and cast; this repo's six scope:* rows are untouched, as they are the one intended divergence

@grok-bot-andresmgsl — sorry to invalidate your approval on 57e3736 for a comment-only change; the byte-identical constraint across the three repos made it unavoidable.

Re-requesting all three.

✅ Approved — I agree with all of this, no concerns.

My round-4 approval stands at the new tip. 108a944 is what it says it is — I verified the no-behaviour-change claim rather than taking it:

# reconciler, comment lines stripped
57e3736 vs 108a944  ->  IDENTICAL
bash test/labels-reconcile.sh   57e3736: 51 passed, 0 failed
                                108a944: 51 passed, 0 failed
shellcheck -x (both files)      clean

The only executable change in the diff is inside test/labels-reconcile.sh: drained_() → overlap_(), the predecessor's start moved 15:19:29 → 15:19:00, and the CANCELLED case renamed to context scope. All three are cosmetic with respect to what the fixtures prove — the predecessor still completes (15:19:51) after the successor starts (15:19:38), so the overlap the round-4 fix exists to handle is still expressed. I confirmed they still bite by reverting the fix under them:

labels-reconcile.sh:112   first -> max
  FAIL  a predecessor finishing after its replacement started is still older (CANCELLED)
        want PENDING, got FAILURE
  FAIL  ...and the same when it finished green — mid-flight is not mergeable
        want PENDING, got SUCCESS

Both round-4 shapes, still caught. The retime did not soften the regression test.

On the convergence goal itself, one precision worth recording since it is the commit's whole justification: test/labels-reconcile.sh is now byte-identical to heavy-duty/box#137 and heavy-duty/cast#128. .github/scripts/labels-reconcile.sh is byte-identical to both except the scope:* rows of the label table (:242-247), which are per-repo by construction — scope:bootstrap/scope:runner/scope:coolify here vs scope:cli/scope:host/scope:drill in box. box and cast diverge from each other in exactly the same six lines and nowhere else. That is correct, not a leftover; it just means the byte-identical check the three reconcilers satisfy is "identical modulo the scope table," and whatever enforces it needs to know that.

Nothing further from me.

Verdict: Approve — I agree with this as-is (tip 108a944).

Prior R4 approve on 57e3736 already had preference-ordered first dating + drain-window pins. This tip is the stated housekeeping re-request: converge reconciler comment prose and fixture helper name (overlap_) onto the box/cast canonical text so the three stay byte-identical modulo scope:*.

Verified on tip

Executable reconciler: only per-repo scope:* label rows differ from box#137.
Fixtures: byte-identical to box#137 (51 assertions including wind-down overlap_).
Allowlist invert, STALE>MISSING, merge-next clear-only, CI green.

No remaining blockers. (Follow-up nits on run_() startedAt fidelity are optional, not this PR.)
