claude-bot-andresmgsl 5bcd8853d4 docs: the run is written down, and the doctrine stops claiming there is no instrument
drill/README.md is the repeatable procedure #107's second checkbox asks
for: prerequisites (the throwaway machine, the tagged key, the fork's
drill workflow, the pins), the invocation, what each leg asserts, where
the record lands. drills/README.md's harness disclaimer flips to point
at the instrument, its legs list and example record match what
drill.sh actually runs and emits, and CONTRIBUTING's drill sentence
names the script. Changelog entry under Unreleased.

# Contributing
This repo is governed by
[heavy-duty/ceremony](https://github.com/heavy-duty/ceremony). **Agents:
read [`.ceremony/AGENTS.md`](.ceremony/AGENTS.md) first** — it routes you to
your role file (builder, reviewer, triage), vendored beside it,
byte-identical to ceremony at the pin named in
[`.github/workflows/release.yml`](.github/workflows/release.yml) and
guarded by the `docs-sync` step in CI. The review-round doctrine — drafts,
whole-round replies, verdicts, the handoff — lives there and in
[`.ceremony/LABELS.md`](.ceremony/LABELS.md); this file keeps only what is
genuinely rig's.
## The PR loop, rig specifics
1. **Fork and branch.** Contributors work from forks; upstream branches are
for maintainers. Title the PR conventionally (`feat:`, `fix:`, `docs:`).
2. **The review panel** (`.github/labels.conf`'s `panel=` line):
`claude-bot-andresmgsl`, `codex-bot-andresmgsl`, `grok-bot-andresmgsl`
the required verdicts for a PR are the panel minus its author. The
maintainer (`danmt`) takes the last word and merges.
3. **Checks must be green**: `shellcheck`, `bash test/cli.sh` and
`bash test/release.sh` locally mirror what CI runs; the db dump/restore
round-trip (`test/db-integration.sh`) executes in CI where Docker is
present. The release guards (`changelog-armed`, `changelog-monotonic`,
`drill-recorded`, `docs-sync`) run as ceremony's pinned actions.
4. **Feature PRs land their changelog entry as part of the PR**: add it
under `CHANGELOG.md`'s `## Unreleased` heading — that section becomes
the release notes verbatim when a release is cut.
## Changelog entries
Every PR that changes behaviour adds one line to `## Unreleased`. One line is
the whole rule — if it wraps more than twice in your editor, cut it down.
- **Say what changed, and stop.** Why it was wrong, how it was found, what it
cost, what it implies — that belongs in the PR body and the commit message,
which is where anyone chasing the reasoning already goes. This file answers
one question: what is different in this version.
- **Any word that can be removed, is removed.**
- **Lead with the surface, not the mechanism.** "`state:needs-human` is set at
handoff" beats "the labels workflow now also wakes on `labeled`".
- **Cite the issue or PR** — `(#96)` — and let the reader follow it for the
rest.
- **Mark a breaking change** with a leading `BREAKING:`.
- Group under `### Added` / `### Changed` / `### Fixed` / `### Removed`.
- No bold run-in headings, no sub-paragraphs, no code blocks, no prose essays.
Good:
- `state:needs-human` is set at handoff, not by the cron (#96)
- An unreadable check rollup no longer reads as "nothing is failing" (#90)
- BREAKING: `--class human|server` is now `--root-door closed|open` (#77)
Not an entry — that is a PR body:
- **`state:needs-human` no longer waits on the cron to become true** (#96) —
the labels workflow now also wakes on `pull_request_target: labeled` and
`unlabeled`, and the author sets it themselves when handing a PR over. A
review landing was never a trigger. There is no `pull_request_review_target`,
and on fork PRs — which is all of them here — ...
## Releasing
A release is a PR, and merging it is the release. The ceremony — the two
doors, the decide table, the stamps, the post-release re-arm — is
heavy-duty/ceremony's machinery, consumed by reference:
[its README](https://github.com/heavy-duty/ceremony/blob/main/README.md)
is the doctrine, `.github/workflows/release.yml` here is the ≤20-line
caller pinning it, and the guards run in `ci.yml` from the same pin.
Bare `X.Y.Z` tags, no `v`; the tag's source tarball is the package
`install.sh` downloads — rig ships no other artifact.
What stays rig's is the **drill** — the real-hardware gate before the
handoff of a release PR, run by `drill/drill.sh` (#105): `rig bootstrap`
converging the machine to its role twice with the second run diffed empty,
`test/db-integration.sh`, the runner lifecycle against a fork, a coolify
install. Rig's drill asserts **convergence** (a machine reaches its role,
idempotently), it runs `--host yes` with `BOX_REF=release/<box-version>` so
it exercises the box that will actually ship, and drills that share a
substrate share **one run ID** so the per-repo records can be joined after
the fact. The full meaning — the fixed candidate-ref pinning that dissolves
the box↔rig recursion, the per-version record files, the waiver rule — is
[`drills/README.md`](drills/README.md); the `drill-recorded` guard enforces
the record on every release tree.
## Labels — who sets what
The taxonomy and state machine are
[`.ceremony/LABELS.md`](.ceremony/LABELS.md); rig's `scope:*` rows live in
`.github/labels.conf` (reconciled by the labels caller) and their path map
in `.github/labeler.yml`. What matters day to day is who sets each kind —
most of it is machinery, and hand-moving a machine-owned label just gets
corrected on the next pass:
| Labels | Set by |
|---|---|
| `state:*` | the labels workflow ([.github/workflows/labels.yml](.github/workflows/labels.yml)) — recomputed from GitHub's own facts on PR events (label changes included) and every 15 minutes. Machine-owned, with one exception: the author sets `state:needs-human` at handoff and the workflow reconciles it. Otherwise never by hand. Exactly one per PR: *whose ball is it.* |
| `blocker:*` | the same workflow, from the same facts — *what is in the way.* Any number per PR, or none. Never by hand: applying one does not stop a merge, and removing one does not unblock anything. Fix the thing and the next sweep drops the label. |
| `stale` | the same workflow — 48h without commits, comments, or reviews. `blocked` PRs are exempt: they are quiet legitimately. |
| `scope:*` on PRs | actions/labeler, from the changed paths ([.github/labeler.yml](.github/labeler.yml)). Additive — you may add more, the machine won't remove them. |
| `scope:*` on issues | you, when opening or triaging — issues have no paths to derive from. |
| `blocked`, `release` | you — automation never guesses intent. |
| `merge-next` | you or the agent owning the queue. Which PR lands first is a judgement about how they conflict, so the workflow never sets it — it only **clears** it, the moment the PR stops being something a human could merge. |
| `bug` / `enhancement` / `documentation` | you, on issues only — a PR's type already lives in its title. |
## Issues
Give issues the same care as PR titles: say the surface in the title, apply a
`scope:` label and a type label (`bug` / `enhancement` / `documentation`) when
you open one, and `blocked` when it waits on something — that is what keeps
the board navigable as the issue count grows.
