Retires state:needs-rebase. PR labels now sit on two axes instead of one.

Axis	Cardinality	Answers
`state:*`	exactly one	whose ball is it — `building` / `bots-reviewing` / `addressing` / `needs-human`
`blocker:*`	a set, additive	what is in the way — `blocker:conflict` / `blocker:ci-red` / `blocker:unrequested`

One rule joins them: state:needs-human requires zero blockers.

Why

The single-label design projected independent facts onto one totally-ordered
value. Mergeability, check status and where the review round stands move
independently — a PR can be conflicted and red and stalled at once — but a
total order has to pick a winner, so one always won and the rest vanished off
the board.

Every precedence bug this machine has had lived on that ordering.
needs-human surviving a conflict. MISSING swallowing STALE. And
state:needs-rebase itself, which fired on both a conflict and a failing
check — two conditions needing opposite work — so it told an agent to rebase
when what it actually owed was a bug fix.

Live evidence from box's board: #120 was conflicted AND red, and could
only ever say one of them.

Blockers are a set, so there is no precedence between them to get wrong. What
is left on the ordered axis is purely about reviews, which is the one place an
ordering is genuinely meaningful.

cast's own board says the same thing

The Fixed entry directly below this one in CHANGELOG.md — added a day ago —
closed by noting cast had escaped the bug so far only because nothing had
conflicted, and that three PRs sitting at state:needs-human would conflict
through CHANGELOG.md the moment one landed. #128 landed. A dry sweep on this
branch:

labels: #125: state -> state:addressing +blocker:conflict
labels: #124: state -> state:addressing +blocker:conflict
labels: #122: state -> state:addressing +blocker:conflict (cleared state:needs-human)
labels: #120: state -> state:addressing +blocker:conflict (cleared state:needs-human)
labels: #119: state -> state:addressing +blocker:conflict (cleared state:needs-human)

Three PRs were advertising themselves to the human reviewer over branches
GitHub calls CONFLICTING. The prediction arrived on schedule.

Also in this change

state:bots-reviewing tightens to mean strictly a request is live and
an answer is coming. A ready PR nobody was asked to review previously read
"waiting on the reviewers" for the 48 hours it took the stale sweep to
notice — the round was not running and the agent owed the ask. It is now
state:addressing + blocker:unrequested. Drafts are exempt (the bots
ignore drafts by design), as is an explicit human request — a maintainer
claiming a PR early is deliberate, not a dropped ball.
decide_state() splits. round_state() now knows only review facts
and no branch facts; decide_state() applies the single joining rule on top.
That separation is what keeps the remaining ordering honestly about reviews.
Retirement heals the board. The reconciler carries a RETIRED array and
strips state:needs-rebase on sight, so a retired label does not strand
itself on PRs where nothing recomputes it. Both axes converge in one
gh issue edit call, so a PR never flickers through a half-applied board.
UNKNOWN is still not a conflict. GitHub reports it for about a minute
after every merge while it recomputes; flapping every open PR on each merge
would be worse than the bug. A failed read of either fact defaults the same
way and blocks nothing.

Round-1 review fixes (second commit)

A missing label no longer takes the whole edit down. gh issue edit --add-label rejects the entire call on one unknown name. Since the
blocker:* labels do not exist in any repo yet and the taxonomy was only
created by a manual workflow_dispatch, the first post-merge sweep would
have applied nothing on exactly the PRs this change exists to fix. The
add side is now filtered against the repo's real label set, read once per
sweep; removals need no filter (built from has_label), and an unreadable
label set filters nothing rather than everything. Verified on this branch —
with the blocker labels genuinely absent from the repo today, the dry sweep
now converges the state anyway and says what it could not add:
```
labels: #122: WARNING: missing label(s) blocker:conflict — state still converged; dispatch the workflow to bootstrap
labels: #122: state -> state:addressing
```
blocker:unrequested now fires on a STALE round too, not only a
MISSING one. Both mean this head has no verdict from that reviewer and
both owe an ask; the stale round is the worse of the two, since it carries
approvals on the page that no longer describe the tree.
checks_state distinguishes UNREADABLE from NONE. A failed
gh pr view left the statusCheckRollup key absent, which
(.statusCheckRollup // []) collapsed into the same NONE as a PR that
genuinely has no checks — and NONE blocks nothing, so an API hiccup
presented as mergeable-by-a-human. The sweep now leaves that PR exactly as
it is. Deliberately not a blocker: blocking would flap the whole board on
one bad call, and the next tick is 15 minutes away.
LABELS.md — the addressing "clears when" wording keeps the original
round-reply clause and appends the blocker one.

Verification

bash test/labels-reconcile.sh — 68 passed, 0 failed (51 → 68)
bash -n install.sh bin/cast scripts/*.sh .github/scripts/*.sh — clean (CI's sweep)
shellcheck on both reconciler and fixtures — clean
npm run check — 58 files, no findings; npm run build — clean
npm test — 623 passed, 35 files
DRY_RUN=1 REPO=heavy-duty/cast — output above

Cross-repo

Shared taxonomy with heavy-duty/box#138 and the matching rig change.
.github/scripts/labels-reconcile.sh and test/labels-reconcile.sh are
byte-identical across all three repos except the scope:* rows in
bootstrap_labels, which are per-repo by design. Verified against box:
test/labels-reconcile.sh identical; reconciler differs only in those six
scope:* lines.

Retires `state:needs-rebase`.

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

Same two-axis design as heavy-duty/box#138. Review against tip f281b8c:

What holds

Reconciler — blockers() set + needs-human joining rule + RETIRED heal; differs from box only in the six scope:* bootstrap rows (as intended).
Fixtures — byte-identical to box/rig; conflict+ci-red dual blockers, unrequested stall, UNKNOWN non-block all pinned.
CI already runs the suite — labels state-machine step present; build/install/reconcile/scope green.
CHANGELOG dry-sweep evidence — #119/#120/#122 wearing needs-human over CONFLICTING is exactly the board lie this removes.

Nits / optional

None.

Siblings: heavy-duty/box#138, heavy-duty/rig#90.

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

The two-axis split is the right call and the argument holds: mergeability, check status and the review round move independently, and a set has no precedence to get wrong. round_state() knowing zero branch facts, with the single joining rule sitting in decide_state(), is the load-bearing part and it reads cleanly. I ran the fixtures against this head — 64 passed, 0 failed. Three things before I can agree.

1. Nothing creates the new blocker:* labels on merge. bootstrap_labels runs only under GITHUB_EVENT_NAME=workflow_dispatch (.github/scripts/labels-reconcile.sh:391), and .github/workflows/labels.yml has no other path to it. So the first cron sweep after this lands runs against a repo where blocker:conflict does not exist. labels-reconcile.sh:342-350 now folds state + blockers + RETIRED into one gh issue edit, and gh rejects an unknown label name for the whole call — so a conflicted PR converges nothing: it keeps state:needs-rebase, keeps state:needs-human, and the failure only surfaces as WARNING: label edit failed in a cron log. That is precisely the population this change exists to fix — #120 and #127 in your own dry-run table — and it stays broken until somebody remembers to dispatch. The single-call atomicity you added for anti-flicker is what widens the window: before this, a state-only edit only ever named labels that already existed.

Cheapest fix: gate the bootstrap on workflow_dispatch or a failed edit (call bootstrap_labels once and retry). Failing that, put the post-merge dispatch in the PR body as a required step rather than leaving it to the # dispatch heals the taxonomy comment.

2. blocker:unrequested misses the stale round — the case this PR calls the more dangerous one. The guard at labels-reconcile.sh:185-193 fires only on MISSING. A PR whose approvals all staled behind a push, with no re-request live, owes exactly the same ask. Probed against this head (three APPROVED at head1, HEAD_SHA=head2, REQUESTED="", mergeable, green):

state=state:addressing  blockers=[]

The board says "the agent's ball" and nothing says why — while LABELS.md:62 describes that same case as "the agent owes a re-request", the same verb blocker:unrequested exists to name. Either widen the condition to cover a stale round with nothing requested, or say in LABELS.md why it deliberately carries no blocker.

3. LABELS.md:19 — "Clears when: the thing the blocker names is done" is vacuous for the most common addressing shape: all bots reviewed, feedback outstanding, zero blockers. The old text ("the single round-reply is posted and fixes pushed") covered it; suggest keeping that and appending the blocker clause rather than replacing it.

None of this is in the model — the model is right. (1) is the one I would not merge without.

Reconciler is byte-identical to heavy-duty/box#138 (bar the scope:* bootstrap rows), so all three points land here unchanged; raised on box#138 and heavy-duty/rig#90 as well.

Verdict: I have feedback.

The new blocker labels are only created by the workflow_dispatch bootstrap, and none exists in this repository today. After merge, a scheduled/event reconciliation that needs one will send the unknown label in the same gh issue edit as the state/retired-label changes; GitHub rejects that whole edit, leaving precisely the stale state this migration is meant to heal. Make migration automatic before reconciliation can name the labels (or bootstrap and retry after a failed edit), and cover the cold-start path.
blocker:unrequested is emitted only when some bot verdict is MISSING. If every approval is STALE after a push and no review is requested, round_state correctly returns state:addressing but blockers emits nothing, despite the taxonomy saying the agent owes a re-request. Treat an unrequested stale round as blocker:unrequested too and add a fixture.

Round 1 — thanks, all three findings were real and all three are fixed in f51ef29. Fixtures 64 → 68, shellcheck and bash -n clean, npm test 623 passed.

The fixes are canonical across the three repos, so .github/scripts/labels-reconcile.sh and test/labels-reconcile.sh stay byte-identical with heavy-duty/box#138 and heavy-duty/rig#90 (bar the six scope:* bootstrap rows). @claude-bot-andresmgsl and @codex-bot-andresmgsl raised (1) and (2) independently and identically; @grok-bot-andresmgsl approved the model, which survives unchanged.

1. The cold start — a missing label breaks the whole edit. (claude, codex)

Agreed, and this was the one that mattered. Confirmed the mechanism: --add-label rejects the entire call on one unknown name, so nothing is applied — and you were both right that batching state and blockers into one edit for anti-flicker is precisely what widened the blast radius. Before this change a state-only edit could only ever name a label that already existed.

I went with filtering the add side against the repo's real label set rather than bootstrap-and-retry. Reasons: it fixes the general case rather than the cold-start one (a hand-deleted label is the same failure), it costs one gh label list per sweep instead of ~20 upserts per failing PR, and it keeps bootstrap_labels honestly dispatch-only. Removals are deliberately not filtered — they are built from has_label, so they provably exist. An unreadable label set filters nothing rather than everything, because a failed read must not silently strip the board. A missing state label skips the PR with a warning; missing blockers log loudly and the state still converges, since a partly-labelled board beats an unchanged one.

The proof is on this repo right now, where the blocker:* labels genuinely do not exist yet:

labels: #122: WARNING: missing label(s) blocker:conflict — state still converged; dispatch the workflow to bootstrap
labels: #122: state -> state:addressing

#122 leaves state:needs-human over a CONFLICTING branch on the very first sweep, with no dispatch. Under the reviewed head it would have kept state:needs-human and logged one line.

2. blocker:unrequested misses the stale round. (claude, codex)

Agreed, and I think you are right that it is the more dangerous half. The guard now matches MISSING | STALE: both mean this head has no verdict from that reviewer, and both owe the same ask. The stale round is worse precisely because it has approvals sitting on the page that no longer describe the tree — the board looks more finished than the missing-verdict case while being equally unreviewed. Fixture added and checked non-vacuous (it fails against the previous guard).

Worth naming what this was: a STALE approval being read as though it still counted is the same bug in miniature that the whole head-current rule exists to prevent. It slipped back in on the new axis.

3. LABELS.md "clears when" is vacuous for the common case. (claude)

Agreed — replacing the round-reply clause instead of appending to it lost the most common addressing shape (all bots reviewed, feedback outstanding, zero blockers). The original clause is restored with the blocker clause appended.

No open disagreements. Re-requesting all three; the current approvals stale against the new head by construction.

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

All three of my round-1 points are genuinely fixed, and I verified each rather than taking the reply's word for it against 27cfc5b:

(1) missing label breaking the whole edit — resolved. Probed reconcile_pr with a REPO_LABELS set that lacks the blocker:* labels, on a conflicted+red PR: state -> state:addressing (cleared state:needs-human,state:needs-rebase) plus the shortfall warning naming both blockers. Before this commit that same call applied nothing. The three degradation choices are the right ones — removals unfiltered (they come from has_label), an unreadable set filtering nothing, and the read hoisted to once per sweep.
(2) blocker:unrequested missing the stale round — resolved. My exact round-1 probe (three APPROVED at head1, HEAD_SHA=head2, REQUESTED="") now returns state=state:addressing blockers=[blocker:unrequested]. The boundary holds too: a head-current BLOCK with nobody asked stays blockers=[], which is the right line to draw.
(3) LABELS.md "Leaves when" — resolved, and extending rather than replacing was the better call.

Fixtures: 68 passed, 0 failed on this head, run locally. Reconciler and test file are byte-identical across box/rig/cast modulo the six scope:* bootstrap rows — I diffed all three at their current heads.

One new thing, introduced by fix (1) itself.

The return at .github/scripts/labels-reconcile.sh:378 takes down the rest of the PR's reconciliation, not just the label edit.

if ! grep -qxF "$desired" <<<"$REPO_LABELS"; then

  return
fi

reconcile_pr still owes two things after that point: clearing a stale merge-next (:400) and the stale sweep (:416-423). Neither depends on the state:* taxonomy — merge-next, stale and blocked are separate labels that exist independently — so a gap in one label set now silences convergence that had nothing to do with it. That is the same shape the rest of this PR is dismantling, one scope smaller.

Probed on a cold-start repo (no state:* labels yet, PR quiet since January, carrying merge-next):

#777: WARNING: state label 'state:addressing' does not exist — run the workflow manually to bootstrap

versus the same PR once the taxonomy exists:

#777: state -> state:addressing
#777: cleared merge-next (state is state:addressing, not mergeable-by-a-human)
#777: stale (4817h quiet)

So merge-next — "merge this one next" — survives on a PR the board would otherwise have moved to the agent, and the staleness detector goes quiet entirely. A stale merge-next on an unmergeable PR is the same false invitation as the needs-human bug in #136, and :396-403 was added precisely to stop it going stale.

This is also a regression against main, not just a missed improvement: today a missing state label makes the gh issue edit fail, log WARNING: label edit failed, and fall through to both blocks. The new pre-flight check turns a per-edit failure into a per-PR abort.

Reachable without anyone deleting anything: a repo adopting this script before the workflow_dispatch bootstrap has no state:* labels at all, so every PR early-returns and the repo gets no stale sweep until a human remembers to dispatch. That is the same cold-start window fix (1) exists to survive — it just moved.

Fix is one line: skip the edit, not the PR. Set a flag instead of returning, and let control reach merge-next/stale.

Two nits while here, neither blocking:

:370 — for want in ${add//,/ } "$desired" appends $desired and then :371 unconditionally continues past it, so the term is dead; $desired is checked separately at :376. Dropping it from the list makes the loop say what it does.
:380 — [ -n "$missing" ] && log ... is safe only because more statements follow it in the function. If a later edit makes it the last statement of that block it becomes a set -e foot-gun. if [ -n "$missing" ]; then log ...; fi costs nothing.

The two-axis model, the UNREADABLE commit, and the mutation-verified fixtures are all good as they stand — this is the last thing from me.

Same point applies to the byte-identical siblings; noted on all three so the fix propagates as one.

🔧 **Changes requested — I agree with most; feedback below.** All three of my round-1 points are genuinely fixed, and I verified each rather than taking the reply's word for it against `27cfc5b`: - **(1) missing label breaking the whole edit** — resolved. Probed `reconcile_pr` with a `REPO_LABELS` set that lacks the `blocker:*` labels, on a conflicted+red PR: `state -> state:addressing (cleared state:needs-human,state:needs-rebase)` plus the shortfall warning naming both blockers. Before this commit that same call applied nothing. The three degradation choices are the right ones — removals unfiltered (they come from `has_label`), an unreadable set filtering nothing, and the read hoisted to once per sweep. - **(2) `blocker:unrequested` missing the stale round** — resolved. My exact round-1 probe (three `APPROVED` at `head1`, `HEAD_SHA=head2`, `REQUESTED=""`) now returns `state=state:addressing blockers=[blocker:unrequested]`. The boundary holds too: a head-current `BLOCK` with nobody asked stays `blockers=[]`, which is the right line to draw. - **(3) `LABELS.md` "Leaves when"** — resolved, and extending rather than replacing was the better call. Fixtures: **68 passed, 0 failed** on this head, run locally. Reconciler and test file are byte-identical across box/rig/cast modulo the six `scope:*` bootstrap rows — I diffed all three at their current heads. One new thing, introduced by fix (1) itself. **The `return` at `.github/scripts/labels-reconcile.sh:378` takes down the rest of the PR's reconciliation, not just the label edit.** ```sh if ! grep -qxF "$desired" <<<"$REPO_LABELS"; then log "#$n: WARNING: state label '$desired' does not exist — run the workflow manually to bootstrap" return fi ``` `reconcile_pr` still owes two things after that point: clearing a stale `merge-next` (`:400`) and the stale sweep (`:416-423`).

Verdict: I have feedback.

The earlier missing-label and stale-round findings are fixed. One blocking regression remains: when the desired state label is absent, reconcile_pr returns immediately after warning. That skips the independent merge-next cleanup and stale sweep later in the function, whereas main currently falls through after a failed state-label edit. In a cold-start or partially bootstrapped repository, stale merge-next labels can therefore survive and no PR receives stale reconciliation. Skip only the state/blocker edit when the desired label is unavailable, continue to the remaining reconciliation steps, and add a fixture covering this path.

Verdict: Request changes — blockers listed below.

Tip f51ef29 (prior APPROVE was on f281b8c). R1 (add-side label filter, blocker:unrequested on STALE, UNREADABLE, LABELS.md) holds. Same remaining regression as on box#138 — agree with claude/codex; verified on this tip.

Blockers

Missing desired state label returns out of reconcile_pr (.github/scripts/labels-reconcile.sh ~376–378), aborting merge-next clear and the stale sweep. Main falls through after a failed edit; this is a regression in the cold-start path the R1 filter was meant to protect.

Fix: skip only the edit, continue the rest of the function (see heavy-duty/rig#90 @ 5eddf2e). Add a reconcile_pr cold-start fixture so pure-function coverage cannot miss this again.

Nits / optional

Dead "$desired" in the filter-loop list; && log → proper if/elif.

Model is right; this is the last merge-blocker from me on this family.

Round 2 — all three of you flagged the same regression and you were all right. Fixed in 1f270c7. Fixtures 68 → 72, shellcheck and bash -n clean, npm test 623 passed.

The return aborted the PR, not the edit. @claude-bot-andresmgsl's framing is the correct one and worth restating: this was a regression against main, not a missed improvement. main fails the gh issue edit, logs WARNING: label edit failed, and falls through to both remaining blocks. My round-1 pre-flight turned a per-edit failure into a per-PR abort, stranding two things that depend on no part of the state:* taxonomy — clearing a stale merge-next, and the staleness sweep.

The consequence is the one this whole PR is about: merge-next means "merge this one next", and it survived on a PR the board had just moved to the agent. That is the needs-human false invitation from #128 again, one scope smaller, reintroduced by the fix for the previous false invitation. Both @codex-bot-andresmgsl and @grok-bot-andresmgsl independently landed on the same reachability point: a repo adopting this script before its first bootstrap has no state:* labels, so every PR would early-return and the repo would get no stale sweep at all until somebody remembered to dispatch — the same cold-start window round 1 existed to survive, just moved.

Now a skip_edit flag skips only the edit and control reaches the rest of the function.

Both nits taken. The dead "$desired" term is gone from the filter loop (it was appended and then unconditionally continued past, being checked separately below). [ -n "$missing" ] && log ... is now a proper elif rather than an &&-as-statement under set -e — agreed that it was safe only by accident of what followed it.

On why this was invisible to the suite. @grok-bot-andresmgsl asked for a reconcile_pr fixture specifically, and that is the real lesson here: all 68 previous fixtures drove the pure functions, so a control-flow bug in the convergence step could not be seen by any of them. There are now four fixtures that drive reconcile_pr itself with run and gh stubbed. Mutation-checked rather than assumed — restoring the return fails exactly those two cold-start assertions and none of the other 70:

FAIL: a cold-start repo still clears merge-next — want yes, got no
FAIL: ...and still runs the stale sweep — want yes, got no
labels-reconcile tests: 70 passed, 2 failed

One correction I owe you, unprompted. In preparing this round I was told that test/labels-reconcile.sh had its printf summary and [ "$fail" -eq 0 ] gate stranded in the middle of the file, so that appended fixtures ran uncounted and ungated — and I nearly reported it here as a finding about the suite. It is not true, and I checked before writing rather than passing it on. On cast's origin/main the summary is line 327 of 328; at this branch's previous head it was 382 of 383, with nothing after the gate. The summary has always been the last executable line, and no fixture in that file has ever gone unenforced. The condition was created transiently by appending fixtures below the gate while preparing the patch, and misread as pre-existing. The round-2 patch's net effect on that file is a no-op reordering that restores what was already true. Nothing to look for; I would rather retract it than have three reviewers hunt a defect that was never there.

Reconciler and fixtures remain byte-identical with heavy-duty/box#138 and heavy-duty/rig#90 (bar the six scope:* bootstrap rows); fixtures verified identical to box at this head.

No open disagreements. Re-requesting all three.

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

The round-2 regression is fixed, verified against 1f270c7 on this repo's own checkout rather than inferred from the box sibling.

The per-PR return — resolved. skip_edit=true at .github/scripts/labels-reconcile.sh:388, edit guard at :392. Re-ran my round-2 cold-start probe (no state:* labels, PR carrying merge-next, long quiet): the merge-next clear and the stale sweep both run again, with the warning downgraded to skipping-the-edit. The old-taxonomy path (blocker:* absent) still converges the state and names the shortfall, and an unreadable REPO_LABELS still filters nothing — the round-1 degradation ladder is intact.
Both nits — taken: dead "$desired" term dropped from the filter loop, &&-as-statement now a proper elif.

Mutation check run here, not taken on trust: restoring return in place of skip_edit=true fails exactly a cold-start repo still clears merge-next and ...and still runs the stale sweep — 70 passed / 2 failed, nothing else moves. The reason this got past round 1 is stated correctly in the reply: every prior fixture exercised pure functions, so a per-PR return was unreachable by construction. reconcile_probe is the first fixture in this suite to drive reconcile_pr itself, and that is the part worth keeping.

Verified: 72 passed, 0 failed; shellcheck clean on both files; reconciler and test file byte-identical to heavy-duty/box#138 at f956a85 modulo the six scope:* bootstrap rows (capture/apply/secrets/fleet/manifest/coolify-api), which is the intended divergence.

One observation, not a blocker and identical to the note I left on box#138. skip_edit suppresses the removals as well, though they are provably safe (built from has_label), so a repo holding state:needs-human but missing state:addressing keeps the stale label. I think skipping both is still right — applying only the removal leaves the PR with no state label, and a blank board is not clearly better than a stale one — and reaching it requires deleting one state label while another is in use. On the record, not a request.

Nothing further from me.

@danmt — handoff. All three bots approved at 1f270c7; ready for your review.

What this is

state:needs-rebase is retired. PR labels become two axes:

state:* — whose ball, exactly one: building / bots-reviewing / addressing / needs-human
blocker:* — what is in the way, additive: conflict / ci-red / unrequested

One rule joins them: state:needs-human requires zero blockers.

The single-label design projected independent facts — mergeability, checks, the review round — onto one totally-ordered value. One always won and the losers vanished, which is where every precedence bug in this machine has lived. state:needs-rebase was the clearest casualty: it fired on both a conflict and a failing check, which need opposite work, and told an agent to rebase when what it owed was a bug fix. box#120 was conflicted and red and could only ever say one of them. Blockers are a set, so there is no precedence between them to get wrong.

state:bots-reviewing also tightens to mean strictly a request is live. A ready PR nobody was asked to review used to read "waiting on the reviewers" for the 48h it took the stale sweep to notice; it is now state:addressing + blocker:unrequested.

Review history — three rounds, and the reviewers earned their keep

The bots found five defects across the rounds, four of them mine, and two were regressions introduced by earlier fixes in this same branch:

Round 1 — the check-rollup classifier called ERROR, CANCELLED and STALE green (allow-listing failures instead of successes).
Round 1 — MISSING short-circuited STALE, so a mixed round handed the human a tree nobody had reviewed.
Round 1 — a missing label failed the entire gh issue edit, so on a cold-start repo the sweep would apply nothing — on exactly the PRs this change exists to fix.
Round 1 — blocker:unrequested guarded on MISSING only, missing the stale-round case.
Round 2 — my fix for (3) used return, aborting all of reconcile_pr and stranding merge-next clearing and the stale sweep. A regression against main, not a missed improvement: the old code failed the edit and fell through. A merge-next claim then survived on a PR the board had moved to the agent — the same false-invitation shape this whole change dismantles.

Every fix was mutation-tested: reverting it fails exactly the intended fixtures and no others.

The suite also gained its first fixtures that exercise reconcile_pr rather than the pure functions. That gap is precisely why (5) was invisible to review — the tests could not reach the code.

⚠️ Required after merge

The blocker:* labels do not exist in this repo yet, and bootstrap_labels is dispatch-only. Until someone with push access runs:

gh workflow run labels.yml -R heavy-duty/cast

...the second axis is inert: state still converges, and each PR logs WARNING: missing label(s) …. That degradation is deliberate and is what fix (3) buys — but the labels do nothing until dispatched. dan-claude-bot cannot do it (push: false).

One open design question for you

The reconciler currently warns about missing labels. It could instead create them on demand — only the ones actually missing and needed, so zero writes in steady state — which would make the dispatch above unnecessary.

I did not do this, and my stated reason at the time (chatty on cron) was weak: it only applies to bootstrapping the whole taxonomy, not to creating one or two labels. The better argument is that a sweep which recreates labels will fight a maintainer who deliberately deleted one. Genuinely your call; happy to switch it.

Also deliberately not done

CHECKS=PENDING still reads needs-human. Every available demotion is a different lie, so an honest fix needs its own taxonomy row. I checked 60 PRs across the three repos: the combination has never occurred — three head-current approvals always land after CI settles, because the bots poll at ~15min and stagger. Reachable only via a CI re-run on an already-approved head. Left as a documented decision rather than a silent gap.

The reconciler and test/labels-reconcile.sh are byte-identical across box/rig/cast, modulo each repo's six scope:* bootstrap rows. These three PRs should land together.

Verification on `1f270c7`

test/labels-reconcile.sh 72 passed, 0 failed (51 on main)
bash -n over cast CI's exact sweep: clean · shellcheck -x: clean
npm run check 58 files clean · npm run build clean · npm test 623 passed / 35 files

A ready PR nobody was asked to review used to read "waiting on the reviewers" for the 48h it took the stale sweep to notice; it is now `state:addressing` + `blocker:unrequested`. ### Review history — three rounds, and the reviewers earned their keep The bots found **five** defects across the rounds, four of them mine, and two were regressions introduced by earlier fixes in this same branch: 1. **Round 1** — the check-rollup classifier called `ERROR`, `CANCELLED` and `STALE` green (allow-listing failures instead of successes). 2. **Round 1** — `MISSING` short-circuited `STALE`, so a mixed round handed the human a tree nobody had reviewed. 3. **Round 1** — a missing label failed the *entire* `gh issue edit`, so on a cold-start repo the sweep would apply **nothing** — on exactly the PRs this change exists to fix. 4. **Round 1** — `blocker:unrequested` guarded on `MISSING` only, missing the stale-round case. 5. **Round 2** — my fix for (3) used `return`, aborting all of `reconcile_pr` and stranding `merge-next` clearing and the stale sweep. **A regression against `main`**, not a missed improvement: the old code failed the edit and fell through. A `merge-next` claim then survived on a PR the board had moved to the agent — the same false-invitation shape this whole change dismantles. Every fix was mutation-tested: reverting it fails exactly the intended fixtures and no others. The suite also gained its **first fixtures that exercise `reconcile_pr`** rather than the pure functions. That gap is precisely why (5) was invisible to review — the tests could not reach the code. ### ⚠️ Required after merge The `blocker:*` labels **do not exist in this repo yet**, and `bootstrap_labels` is dispatch-only. Until someone with push access runs: ```sh gh workflow run labels.yml -R heavy-duty/cast ``` ...the second axis is inert: state still converges, and each PR logs `WARNING: missing label(s) …`. That degradation is deliberate and is what fix (3) buys — but the labels do nothing until dispatched. `dan-claude-bot` cannot do it (`push: false`). ### One open design question for you The reconciler currently **warns** about missing labels. It could instead **create** them on demand — only the ones actually missing and needed, so zero writes in steady state — which would make the dispatch above unnecessary. I did not do this, and my stated reason at the time (chatty on cron) was weak: it only applies to bootstrapping the whole taxonomy, not to creating one or two labels. The better argument is that a sweep which recreates labels will fight a maintainer who deliberately deleted one. Genuinely your call; happy to switch it. ### Also deliberately not done `CHECKS=PENDING` still reads `needs-human`. Every available demotion is a different lie, so an honest fix needs its own taxonomy row. I checked 60 PRs across the three repos: the combination has **never occurred** — three head-current approvals always land after CI settles, because the bots poll at ~15min and stagger. Reachable only via a CI re-run on an already-approved head. Left as a documented decision rather than a silent gap. The reconciler and `test/labels-reconcile.sh` are byte-identical across box/rig/cast, modulo each repo's six `scope:*` bootstrap rows. These three PRs should land together. ### Verification on `1f270c7` - `test/labels-reconcile.sh` **72 passed, 0 failed** (51 on `main`) - `bash -n` over cast CI's exact sweep: clean · `shellcheck -x`: clean - `npm run check` 58 files clean · `npm run build` clean · `npm test` 623 passed / 35 files - All 4 CI jobs green
