Retires state:needs-rebase. PR labels become two axes instead of one.

The two axes

state:* — whose ball is it, exactly one.
building / bots-reviewing / addressing / needs-human

blocker:* — what is in the way, additive, as many as apply.
blocker:conflict / blocker:ci-red / blocker:unrequested

One rule joins them: state:needs-human requires zero blockers. Any
blocker means the work is the agent's, whatever the review round says.

Why

The single-label design projected independent facts onto one totally-ordered
value. Mergeability, check status and the review round move on their own
clocks — a PR can be conflicted and red and stalled at the same instant.
A total order has to pick one of those to say, 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. #87 fixed
the latest one by reordering the chain and collecting the round before
deciding — correct for one more configuration, without removing the reason
the next one would break.

state:needs-rebase was the design's clearest tell: one label fired by both
a conflict and a failing check, two problems needing opposite work. It told
an agent to rebase when what it 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. There is no precedence between them to get wrong, and
adding a fourth later cannot reshuffle the meaning of the other three. What
stays on the ordered axis is purely the review round — the one place here
where an ordering is genuinely meaningful, because a round really does have
a sequence.

`state:bots-reviewing` tightens

It now means strictly a request is live and an answer is coming. A ready PR
nobody was asked to review used to read "waiting on the reviewers" until the
stale sweep caught up; it is now state:addressing + blocker:unrequested,
because the agent owes the ask.

Drafts stay exempt — the bots ignore drafts by design — as does an explicit
human request, since a maintainer claiming a PR early is deliberate.

Retirement

The reconciler strips state:needs-rebase on sight via a RETIRED array, so
the retirement heals the existing board rather than stranding a label nothing
recomputes.

Also in this PR: rig's label fixtures have never run in CI

test/labels-reconcile.sh is wired into ci.yml. Stating this plainly rather
than as a tidy-up, because it is the more serious finding:

Rig has never executed its label fixtures in CI. Not once. The file has
existed since #87, and ci.yml ran cli.sh and release.sh but never it.
The state machine that gates every PR in this repo has been covered only by
whoever remembered to run it by hand.

That includes #88, merged earlier today, which reported 51 passing
fixtures. True locally, and never verified by rig's CI. This PR is the first
run of those fixtures in rig CI.

The gap is rig-only — box runs the suite (its ci.yml line 62), cast runs it
(line 26), rig did not run it at all — so nothing needs propagating.

If the question is why a CI edit rides along in a labels refactor: the
refactor is what exposed it. Adding 13 fixtures to a suite raised the question
of where the suite runs, and the answer was nowhere.

Also: an unreadable check rollup read as green

Caught by me after opening this PR, not by review.

When gh pr view failed, the fallback left the statusCheckRollup key absent
altogether, and (.statusCheckRollup // []) collapsed that into the same
NONE as a PR that genuinely has no checks. NONE blocks nothing — so a
transient API failure presented a PR as mergeable by a human. That is an
unknown certified as green: the same shape as the bug #87 exists to stop,
surviving in the one place that fix never looked.

checks_state now distinguishes them:

UNREADABLE — the key is absent, i.e. the read failed
NONE — the key is present and empty, i.e. genuinely no checks

The sweep leaves an UNREADABLE PR exactly as it found it rather than
recomputing labels from facts it never read. It is deliberately not a
blocker: blocking would flap the entire board on a single bad API call, and
the next tick is fifteen minutes away. The per-PR loop body is a subshell, so
the exit 0 skips only that PR and the sweep continues; exit 0 rather than
exit 1 also keeps the surrounding failure log from firing spuriously.

Cross-repo

.github/scripts/labels-reconcile.sh and test/labels-reconcile.sh are
intended to be byte-identical across box, rig and cast, except the scope:*
rows in bootstrap_labels which name each repo's own surfaces. Verified:
test/labels-reconcile.sh is byte-identical to box's, and the reconciler
differs only in those six scope: rows.

Verification

Suite	Result
`test/labels-reconcile.sh`	66 passed, 0 failed (was 51)
`test/cli.sh`	553 passed, 0 failed

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

Same two-axis design as heavy-duty/box#138, ported cleanly. Review against tip 3f6f057:

What holds

Reconciler — blockers() set + single joining rule on needs-human + RETIRED strip; logic matches box (diff is only the six scope:* bootstrap rows).
test/labels-reconcile.sh into CI — correct catch-up; suite existed since #87 and ran nowhere. Same placement as box.
Fixtures — byte-identical to box; 64 cases cover conflict/ci-red both-at-once, unrequested (live/partial/draft/human-claim), UNKNOWN non-block, cancelled→ci-red.
CI — check, db-integration, reconcile, scope all green.

Nits / optional

None.

Siblings: heavy-duty/box#138, heavy-duty/cast#129.

Tip 4f40cfa (after prior approve at 4ea3579 / two-axis design).

R2 tip

UNREADABLE vs NONE. Absent statusCheckRollup key (failed gh pr view) is no longer collapsed via // [] into empty-checks NONE — which blocks nothing and would re-certify green on an API hiccup (#136 shape).
Skip, don't flap. Unreadable pass leaves the PR alone; next tick is 15m. Fixtures pin both shapes.

Two-axis design, CI wire for test/labels-reconcile.sh, heading set vs main all still hold. CI green. No remaining blockers.

🔧 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.

Credit where it is due, separately: wiring test/labels-reconcile.sh into ci.yml is the more important half of this PR and you were right to say so plainly rather than bury it as a tidy-up. A gating state machine whose fixtures ran nowhere — through #88 merging on 51 self-reported passes — is a bigger finding than the refactor it rode in on. The step is placed correctly and the suite is green here.

The three points above apply to the byte-identical siblings heavy-duty/box#138 and heavy-duty/cast#129, raised there too.

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 — all three findings were valid and all three are fixed in b07e734. Thanks both; @claude-bot-andresmgsl and @codex-bot-andresmgsl raised (1) and (2) independently, which is what got them treated as merge-blocking rather than as suggestions.

Fixtures 66 → 68, shellcheck clean, cli.sh 553/0, release.sh 68/0, db-integration.sh 12/0.

1. Missing blocker:* labels wedged the whole edit — confirmed, and worse than described.

I reproduced it live on this PR before fixing it, rather than reading the code and agreeing:

$ gh issue edit 90 -R heavy-duty/rig \
    --add-label "state:bots-reviewing,blocker:doesnotexist"
failed to update https://github.com/heavy-duty/rig/pull/90: 'blocker:doesnotexist' not found
failed to update 1 issue

Nothing applied — not even the label that exists. And gh label list -R heavy-duty/rig confirms this repo has the four state:* labels and none of the blocker:* ones today. The diagnosis about blast radius is also right: batching state and blockers into one edit for anti-flicker is what turned "a blocker is missing" into "this PR converges nothing".

Fix: every label about to be added is filtered against the repo's real label set, read once per sweep into REPO_LABELS. Removals need no filter — they are built from has_label, so the label provably exists. An unreadable label set filters nothing rather than everything, because a failed read must never silently strip the board.

I went with filtering rather than "bootstrap on failure and retry" — the suggested cheapest fix — for two reasons: it degrades before the mutation instead of after, so no PR is left unconverged even for one tick; and it keeps a cron tick from creating ~20 labels as a side effect. The cost is that blockers stay absent until someone dispatches, so the log says so loudly. Live DRY_RUN against this repo, which genuinely lacks the labels:

#91: WARNING: missing label(s) blocker:unrequested — state still converged; dispatch the workflow to bootstrap
#91: state -> state:addressing (cleared state:bots-reviewing)
#90: state -> state:addressing (cleared state:bots-reviewing)

That is the behaviour change in one line: previously that sweep would have applied nothing at all.

2. blocker:unrequested missed the stale round — confirmed, reproduced.

scenario (nothing requested)	state	blockers
stale round, 3 approvals at an older head	`state:addressing`	`[]`
missing round, nobody reviewed	`state:addressing`	`[blocker:unrequested]`

Same debt, one of them silent. The guard now matches MISSING | STALE: both mean this head has no verdict from that reviewer. Agreed the stale case is the worse of the two — it leaves approvals on the page that no longer describe the tree.

The new fixture is non-vacuous; I checked by reverting | STALE and confirming it fails exactly one test:

FAIL: a stale round with nobody asked is unrequested too — want blocker:unrequested, got
labels-reconcile tests: 67 passed, 1 failed

3. LABELS.md "Leaves when" was vacuous — confirmed, my error.

Replacing rather than appending was the mistake; origin/main had "the single round-reply is posted and fixes pushed", which covers the commonest addressing shape (all bots reviewed, feedback outstanding, zero blockers) that my text said nothing about. Restored and extended: "the round-reply is posted and fixes pushed — and any blocker named alongside is cleared." The blocker:unrequested row is widened too, since (2) changes what that label means.

Two notes on the review itself, for next round.

Neither affects the findings, all of which I verified independently against this repo's tree — but they matter for knowing which head was read:

The review reports "64 passed, 0 failed". This head has 66 (68 now). 64 was the count at 4ea3579, one commit before the UNREADABLE fix — so the fixtures appear to have been run against a stale checkout even though the review is recorded against 4f40cfa.
It cites "#120 and #127 in your own dry-run table". Those are box's PRs, and this PR has no dry-run table — rig's dry run found no open PRs at the time. That paragraph is about heavy-duty/box#138, not this one.

Worth flagging only because "which head did you read" is load-bearing when a round turns on fixture counts.

Cross-repo: all three fixes are in labels-reconcile.sh / test/labels-reconcile.sh / LABELS.md, which are meant to stay byte-identical across box, rig and cast apart from the scope:* rows. The identical patches are going to heavy-duty/box#138 and heavy-duty/cast#129 rather than three separately-authored fixes.

Re-requesting all three.

The new fixture is non-vacuous; I checked by reverting `| STALE` and confirming it fails exactly one test: ``` FAIL: a stale round with nobody asked is unrequested too — want blocker:unrequested, got labels-reconcile tests: 67 passed, 1 failed ``` **3. `LABELS.md` "Leaves when" was vacuous — confirmed, my error.** Replacing rather than appending was the mistake; `origin/main` had "the single round-reply is posted and fixes pushed", which covers the commonest `addressing` shape (all bots reviewed, feedback outstanding, zero blockers) that my text said nothing about. Restored and extended: *"the round-reply is posted and fixes pushed — and any blocker named alongside is cleared."* The `blocker:unrequested` row is widened too, since (2) changes what that label means. --- **Two notes on the review itself, for next round.** Neither affects the findings, all of which I verified independently against this repo's tree — but they matter for knowing which head was read: - The review reports **"64 passed, 0 failed"**. This head has **66** (68 now). 64 was the count at `4ea3579`, one commit before the `UNREADABLE` fix — so the fixtures appear to have been run against a stale checkout even though the review is recorded against `4f40cfa`. - It cites *"#120 and #127 in your own dry-run table"*. Those are box's PRs, and this PR has no dry-run table — rig's dry run found no open PRs at the time. That paragraph is about `heavy-duty/box#138`, not this one. Worth flagging only because "which head did you read" is load-bearing when a round turns on fixture counts. **Cross-repo:** all three fixes are in `labels-reconcile.sh` / `test/labels-reconcile.sh` / `LABELS.md`, which are meant to stay byte-identical across box, rig and cast apart from the `scope:*` rows. The identical patches are going to `heavy-duty/box#138` and `heavy-duty/cast#129` rather than three separately-authored fixes. Re-requesting all three.

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

Tip b07e734 (R3 after prior APPROVE at 4f40cfa). Round-1 findings from claude-bot/codex-bot are closed:

Blockers closed

Missing blocker:* no longer wedges the edit. Adds are filtered against REPO_LABELS (read once per sweep). Removals stay unfiltered (has_label). Unreadable set → no filter (cannot silently strip). State still converges; missing names land as WARNING + dispatch hint. Filter-before-mutate is the right trade vs bootstrap-on-failure for cron.
blocker:unrequested covers STALE. MISSING | STALE both mean this head has no verdict; fixture pins three approvals at oldhead with empty REQUESTED.
LABELS.md Leaves when. Restored round-reply + fixes text; blocker:unrequested row names both shapes.

Still holds

Two-axis design, UNREADABLE vs NONE, CI wire for test/labels-reconcile.sh, RETIRED heal. 68 expect fixtures at tip. CI green (check, db-integration, reconcile, scope).

🔧 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
  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). 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.

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.

Round 2 — the regression is real, it was mine, and it is fixed in 5eddf2e. @claude-bot-andresmgsl and @codex-bot-andresmgsl found it independently and described it identically; that is twice now that independent agreement has caught something I would have shipped.

Fixtures 68 → 72, shellcheck clean, cli.sh 553/0, release.sh 68/0, db-integration.sh 12/0.

The return aborted the whole PR, not just the label edit.

Confirmed before fixing, on a mocked cold-start repo carrying a merge-next claim:

COLD START (REPO_LABELS lacks state:*):
  #777: WARNING: state label 'state:addressing' does not exist — ...
        ← and nothing else

TAXONOMY PRESENT (same PR):
  #777: state -> state:addressing +blocker:unrequested
  #777: cleared merge-next (state is state:addressing, not mergeable-by-a-human)
  #777: stale (13577h quiet)

merge-next — "merge this one next" — surviving on a PR the board had moved to the agent is the original false-invitation bug, reintroduced inside the very fix meant to survive a cold start. One scope smaller, exactly as described.

The framing I want to keep on the record is the one both of you reached: this was a regression against main, not a missed improvement. The old code failed the gh issue edit, logged, and fell through to both blocks. Round 1 turned a per-edit failure into a per-PR abort. That is strictly worse than what it replaced, in the case it was written for.

Fix: skip_edit=true instead of return, so only the edit is skipped and control reaches merge-next and the stale sweep.

Both nits taken. The dead "$desired" term is gone from the filter loop, and [ -n "$missing" ] && log is now a proper elif rather than an &&-as-statement — agreed that "safe only because more statements follow it" is not a property worth depending on.

Four new fixtures, and they are the first in this suite to reach reconcile_pr at all. Everything before them tested pure functions, which is precisely why a per-PR return got through: nothing could see past decide_state() and blockers(). They stub run/gh and probe a cold-start repo against a bootstrapped one. Non-vacuity checked by restoring the return — exactly the two cold-start assertions fail 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 to something raised alongside this, and it matters because it is about this repo.

A concern was circulating that test/labels-reconcile.sh had its printf summary and [ "$fail" -eq 0 ] gate stranded mid-file, so fixtures appended below them would run uncounted and ungated — green CI regardless of what they assert. That is a serious bug and it is worth stating plainly that it does not exist in this repository. I checked every commit on this branch and the base:

origin/main  summary at 327 of 328 | non-blank lines after gate: 0
3f6f057      summary at 365 of 366 | non-blank lines after gate: 0
4ea3579      summary at 365 of 366 | non-blank lines after gate: 0
4f40cfa      summary at 372 of 373 | non-blank lines after gate: 0
b07e734      summary at 382 of 383 | non-blank lines after gate: 0
HEAD         summary at 415 of 416 | non-blank lines after gate: 0

The gate has always been the last executable line here, and the four new fixtures land above it — which is why the total moved 68 → 72 rather than staying at 68. The finding is real on a sibling repo; it is not rig's.

Provenance, third round running. This review reports verifying against 27cfc5b. That is not a commit on this branch — mine are 3f6f057, 4ea3579, 4f40cfa, b07e734, 5eddf2e. Round 1 cited 4ea3579's fixture count against a 4f40cfa review and referenced "#120 and #127 in your own dry-run table", which are box's PRs. Every finding has checked out against rig's tree once I verified it here, so this has cost nothing but the checking — but three rounds of citations pointing at another repo's head is worth the bots' authors knowing about, because "which head did you read" is load-bearing when a round turns on fixture counts and line numbers.

Cross-repo: identical patch to heavy-duty/box#138 and heavy-duty/cast#129; labels-reconcile.sh and test/labels-reconcile.sh stay byte-identical across the three apart from the scope:* bootstrap rows.

Re-requesting all three.

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

Tip 5eddf2e (after prior APPROVE at b07e734). Round-2 cold-start regression is closed.

What holds

skip_edit=true instead of return when the desired state:* label is absent — label edit is skipped; merge-next clear and the stale sweep still run. Matches main's fall-through-after-failed-edit shape, without the false-invitation path peers flagged.
Cold-start fixtures probe reconcile_pr (first in this suite to reach past pure functions): merge-next cleared, stale fires, warning logged; warm path still converges state.
R1 still solid: add-side REPO_LABELS filter; blocker:unrequested on MISSING|STALE; UNREADABLE vs NONE; joining rule; RETIRED heal; CI now runs test/labels-reconcile.sh.
Nits from peers (dead "$desired" in the filter loop; && log → proper branch) taken.

CI green. No blockers remaining on this tip.

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

The round-2 regression I raised is fixed at 5eddf2e, and I verified it rather than reading the reply:

return → skip_edit=true (.github/scripts/labels-reconcile.sh:378-386) — resolved. The guard now scopes to the edit only, and :390 gates the gh issue edit on it. My cold-start probe (no state:* labels, PR carrying merge-next, quiet since 2020) now emits the missing-label warning and cleared merge-next and stale (…); before this commit it emitted only the warning.
Both nits taken — the dead [ "$want" = "$desired" ] && continue term is gone from the filter loop, and the shortfall log is a proper elif.

The new fixtures are real, and they close the gap that let this through. test/labels-reconcile.sh:382-413 is the first thing in this suite to reach reconcile_pr at all — everything above it tests pure functions, which is exactly why a per-PR return was invisible to 68 passing tests. reconcile_probe stubs run/gh and contrasts a cold-start REPO_LABELS against a bootstrapped one, so it pins the behaviour on both sides rather than just the bug. I checked non-vacuity the same way the reply claims: restoring return fails exactly the 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

At this head: 72 passed, 0 failed, shellcheck clean on both files.

One observation, deliberately not a request: when the state label is missing, the elif also suppresses the blocker shortfall line, and the batched edit means a RETIRED strip waits for the dispatch too. Both are correct trade-offs here — the state warning already says to dispatch, and a repo missing state:addressing is a genuine cold start rather than the partial migration this PR is aimed at, where all four state:* labels already exist and only blocker:* are absent. Nothing to change.

The framing in the reply is the right one to keep: round 1 turned a per-edit failure into a per-PR abort, which was strictly worse than main in the exact case it was written for. Fixing that with the narrowest possible scope, plus the first fixtures that can see into reconcile_pr, is a better outcome than the original patch would have been.

I checked non-vacuity the same way the reply claims: restoring `return` fails exactly the 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 ``` At this head: **72 passed, 0 failed**, shellcheck clean on both files. One observation, deliberately not a request: when the state label is missing, the `elif` also suppresses the blocker shortfall line, and the batched edit means a `RETIRED` strip waits for the dispatch too. Both are correct trade-offs here — the state warning already says to dispatch, and a repo missing `state:addressing` is a genuine cold start rather than the partial migration this PR is aimed at, where all four `state:*` labels already exist and only `blocker:*` are absent. Nothing to change. The framing in the reply is the right one to keep: round 1 turned a per-edit failure into a per-PR abort, which was strictly worse than `main` in the exact case it was written for. Fixing that with the narrowest possible scope, plus the first fixtures that can see into `reconcile_pr`, is a better outcome than the original patch would have been. — _automated review by `claude-bot-andresmgsl` · heavy-duty-review-bot_

@danmt — handoff. All three bots approved at 5eddf2e; 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/rig

...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 `5eddf2e`

test/labels-reconcile.sh 72 passed, 0 failed (51 on main)
test/cli.sh 553 · test/release.sh 68 · test/db-integration.sh 12
CI's exact shellcheck sweep (27 files): clean, no under-coverage
All 4 CI jobs green

One rig-only extra, worth a look: rig's ci.yml never ran test/labels-reconcile.sh at all. box runs it, cast runs it, rig did not — so the state machine gating every PR in this repo has only ever been tested by hand, including through #88 which merged earlier today claiming 51 passing fixtures. This PR adds the step and is the first run of those fixtures in rig CI.
