dan-claude-bot f51ef29b79 fix(labels): never name a label the repo lacks, and do not read an unreadable rollup as green
Round-1 review fixes, canonical across box/rig/cast.

`gh issue edit --add-label` rejects the WHOLE call on one unknown label name,
applying nothing. Batching state and blockers into a single edit for
anti-flicker meant one missing `blocker:*` would take the `state:*`
convergence down with it — and since the taxonomy was only ever created by a
manual workflow_dispatch, the first sweep after the two-axis change would have
healed nothing on exactly the PRs it exists to fix, surfacing only as a log
line. 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, so they
provably exist); an unreadable label set filters nothing rather than
everything, because a failed read must not silently strip the board.

`checks_state` returns UNREADABLE when the `statusCheckRollup` key is absent —
what a failed `gh pr view` leaves behind — distinct from NONE for a
present-but-empty array. Collapsing the two let an API hiccup present as
"nothing is failing", i.e. as mergeable-by-a-human: the unknown-certified-as-
green shape this machine exists to stop, surviving where the #128 fix never
looked. The sweep now leaves that PR exactly as it is. Deliberately not a
blocker: blocking would flap the whole board on one bad call.

`blocker:unrequested` also fires on a STALE round, not just 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.

Fixtures 64 -> 68.

# Labels
How this repo uses GitHub labels. The taxonomy is shared across the
heavy-duty repos (box, rig, cast) — only the `scope:` set differs per repo,
because it names this repo's actual surfaces.
## State — who is the ball with? (PRs, exactly one)
Every open PR carries exactly one `state:` label, and it answers the only
question a board scan actually asks: *who is this PR waiting on?* The states
mirror the review loop this repo runs — PRs open as drafts, three reviewer
bots pick up ready PRs with reviews requested, each round is answered in a
single reply, and a human takes the final review.
| Label | Color | Waiting on | Enters when | Leaves when |
|---|---|---|---|---|
| `state:building` | `#FBCA04` | the coding agent, still building | PR opened as draft | marked ready + bot reviews requested |
| `state:bots-reviewing` | `#1D76DB` | the reviewer bots to finish the round | ready with reviews requested, or fixes pushed and reviews re-requested | all three bots have reviewed the round |
| `state:addressing` | `#D93F0B` | the coding agent to reply, fix, or ask | all bots reviewed and not all approved; or nobody was asked; or a blocker is up | the round-reply is posted and fixes pushed — and any blocker named alongside is cleared |
| `state:needs-human` | `#8250DF` | the human reviewer | the PR **could be merged right now**: no blockers, three formal head-current approvals — and the human review is requested | merged — or changes requested, which cycles back to `state:addressing` |
`bots-reviewing` and `addressing` are deliberately distinct: staleness in the
first means *poke the bots*, staleness in the second means *the agent dropped
the ball*. Collapsing them loses exactly the information a sweep needs.
`bots-reviewing` therefore means strictly *a request is live and an answer is
coming* — a PR nobody was asked to review is the agent's ball, not the bots'.
## The second axis: `blocker:*`
State answers *whose ball is it*. Blockers answer *what is in the way*, and
unlike states they are *facts about the branch* — mutually independent, so a
PR carries as many as apply.
| Label | Color | Means | Clears when |
|---|---|---|---|
| `blocker:conflict` | `#B60205` | GitHub says `CONFLICTING` — the agent owes a **rebase** | it merges cleanly |
| `blocker:ci-red` | `#B60205` | a check failed — the agent owes a **fix**, which a rebase will not provide | checks are green |
| `blocker:unrequested` | `#E99695` | this head has no verdict from somebody — never reviewed, or staled by a push — and **nobody was asked** for one | reviews are requested |
One rule joins the axes: **`state:needs-human` requires zero blockers.** Any
blocker means the work is the agent's, whatever the review round says.
This split exists because the single-label version kept lying. Independent
facts were projected onto one totally-ordered label, so one always had to win
and the losers vanished off the board: a PR that was *both* conflicted and red
could only say one of them, and `needs-rebase` told an agent to rebase when
what it actually owed was a bug fix. Precedence between two blockers is not a
question a set has to answer, which is why every ordering bug this machine has
had — `needs-human` surviving a conflict, `MISSING` swallowing `STALE` — lived
on the axis that had to be totally ordered.
`state:needs-rebase` was the first attempt at this and is **retired**; the
reconciler strips it on sight so no PR is left carrying a label nothing
recomputes.
**`state:needs-human` means one thing: a human could merge this right now.**
The label is the only signal a maintainer scanning the board (or a phone)
actually reads, and one that says "your turn" on an unmergeable PR is worse
than no label at all. So beyond the blockers, one review fact also outranks an
explicit human request:
- **nobody reviewed *this* head** — every approval staled by a push → `state:addressing`,
because the agent owes a re-request
That case is more dangerous than any blocker: a blocked PR at least shows an X
or a disabled merge button, while a staled-approval PR reads green, mergeable
and "waiting on the human" over code no reviewer has seen.
`UNKNOWN` mergeability is deliberately **not** treated as a conflict. GitHub
reports it for about a minute after every merge while it recomputes, and
flapping every open PR through `blocker:conflict` on each merge would be worse
than the bug this fixes. A failed read of either branch fact degrades to the
same "do not know" value, for the same reason.
An *unfinished* round still yields to an explicit human request — a maintainer
pulling a PR to themselves early is a deliberate act. `MISSING` (nobody has
reviewed yet) and `STALE` (everyone reviewed something else) are different
facts and are treated differently.
## Cross-cutting (PRs and issues)
| Label | Color | Meaning |
|---|---|---|
| `stale` | `#B60205` | No activity for 48h. Sweep-managed, never hand-applied. `state:building` + `stale` is precisely a forgotten draft. |
| `blocked` | `#6A737D` | Waiting on another PR or issue to land first. Quiet *legitimately* — the staleness sweep skips it. |
| `release` | `#0E8A16` | Release flow, versioning, and packaging work. |
| `merge-next` | `#0E8A16` | Head of the merge queue — **merge this one next**. Queue order is *intent* (which PR lands first, given how they conflict), so the reconciler never sets it: you or the agent maintaining the queue do. The reconciler only **clears** it, the moment the PR stops being something a human could merge — so it cannot go stale the way `state:needs-human` did. |
## Scope — which surface? (PRs and issues, any number)
All scopes share one calm color, `#C5DEF5` — scopes locate, states alert.
| Label | Covers |
|---|---|
| `scope:capture` | `draft.ts`, `capture.ts` — reading the live world into a manifest |
| `scope:apply` | `apply.ts`, `diff.ts`, `destroy.ts` — reconciling the manifest onto Coolify |
| `scope:secrets` | `secrets.ts`, age handling, the encrypted state repo |
| `scope:fleet` | `fleet.ts`, `inventory.ts`, `server.ts` — placement and the server side |
| `scope:manifest` | `manifest.ts`, `resolve.ts`, `envtemplate.ts` — the manifest language itself |
| `scope:coolify-api` | `coolify.ts`, the OpenAPI reference — the client surface |
## Issue types
`bug`, `enhancement`, `documentation` — issues only. PRs carry their type in
the conventional title (`feat:`, `fix:`, `docs:`), so typing a PR with a label
would just say the same thing twice, drifting apart eventually.
## Maintenance
State labels are written by automation, never by hand. Every state above is
derivable from GitHub's own facts — the draft flag, requested reviewers,
review states, push timestamps — so the labels workflow
([.github/workflows/labels.yml](.github/workflows/labels.yml)) recomputes the
state and reconciles labels statelessly, on a 15-minute cron plus PR events.
A hand-moved label is a lie waiting to happen; the workflow asserts the
effective state instead. `scope:` labels on PRs are applied from the changed
paths by actions/labeler ([.github/labeler.yml](.github/labeler.yml));
[CONTRIBUTING.md](CONTRIBUTING.md) says who sets what.
The same workflow bootstraps the taxonomy: a manual dispatch creates any
missing label idempotently. To create them by hand (needs push access):
```sh

gh label create "blocker:ci-red" --color B60205 --description "A check is failing — the agent owes a fix (not a rebase)" --force
gh label create "blocker:unrequested" --color E99695 --description "Somebody still owes a verdict and nobody was asked for one" --force
