claude-bot-andresmgsl af48581973 drill: the 0.1.0 record, and the first-release caveat in the doctrine
drills/0.1.0.md — six probes plus (g), run on the disposable scratch repo
against the candidate SHA, every refusal checked for droppings; the pin
deviation (fork ref, CEREMONY_SELF_REF -> candidate SHA in both carriers)
recorded under its own heading per triage's ruling on #11. drills/README.md
gains the first-release caveat that ruling asked for: the first drill can
never take the pure pinned consumer path, and must not fix that by putting
a tag-shaped branch in the canonical ref namespace.

# 0.1.0 — drill record
Run 2026-07-22, by `claude-bot-andresmgsl`, against the release candidate
`heavy-duty/ceremony@dbf857a94a7c4b068962efbccc996b41c5e4ab89` (main at the
time — the ceremony PR adds only `VERSION`, the changelog stamp, this record,
and a doctrine caveat; no machinery differs between the drilled tree and the
released one).
Where: scratch private repo `claude-bot-andresmgsl/ceremony-drill-0.1.0`,
carrying the `docs/CONSUMERS.md` caller stubs verbatim (modulo the pin
deviation below) and a fixture consumer tree in the armed state (`VERSION`
`0.1.0-dev`, `## Unreleased` on top, `drills/`). Deleted after this record
was written, per `drills/README.md`: the repo is the evidence's scaffolding,
this file is the evidence. Run ids below are kept for the record's own
audit trail; they died with the repo.
## The deviation: the first release cannot take the pure consumer path
`CEREMONY_SELF_REF` is `"0.1.0"` — the ref this drill exists to rehearse
creating. Demonstrated live before working around it: the release caller
pinned `@0.1.0` per the stubs died at workflow resolution before any job
started (run 29966400928) — the deadlock #44's bypass solves for ceremony
itself, hit from the consumer side, where no bypass can exist.
Ruled on #11 by triage: **no `0.1.0` branch on `heavy-duty/ceremony`** — a
drill must not leave a hazard in the canonical ref namespace (a branch
shadowing the tag every consumer pins) to prove the namespace works. The
drill instead pinned the scratch callers to the fork ref
`claude-bot-andresmgsl/ceremony@drill/0.1.0`: the candidate tree with
exactly one line changed per pin carrier (`release.yml` and `labels.yml`,
both — `self-ref-check.sh` requires the carriers to agree),
`CEREMONY_SELF_REF: "0.1.0"``"dbf857a94a7c4b068962efbccc996b41c5e4ab89"`.
Every `.ceremony-src` byte the doors executed — `lib/`, `actions/`, decide —
still came from `heavy-duty/ceremony` at the candidate SHA; the fork
supplied orchestration YAML differing by the one line the ceremony stamps
each release anyway. From `0.2.0` on, a real tag exists behind every
candidate and the pure pinned path drills as written.
## The probes
| # | probe | run | result |
|---|---|---|---|
| a | merge-door ceremony | 29966647167 (attempt 1) | ✅ exactly one release |
| b | mislabeled ordinary PR | 29966530098 | ✅ green NOTICE no-op |
| c | bare-version PR, no label | 29966562846 | ✅ refused, red, created nothing |
| d | re-run of the completed ceremony | 29966647167 (attempt 2) | ✅ refused, red, created nothing |
| e | tag door, manual matching tag | 29966718335 | ✅ published, no bump |
| f | tag door, mismatched tag | 29966744675 | ✅ refused, red, created nothing |
| g | labels bootstrap from nothing | 29966488038 | ✅ taxonomy created |
**(a) The ceremony.** PR `release: 0.1.0` — hand-set `release` label,
`VERSION` `0.1.0-dev``0.1.0`, changelog stamped `## 0.1.0 — 2026-07-22`
with an empty `## Unreleased` re-armed above it. Merged. The one run:
facts `ver='0.1.0' base_ver='0.1.0-dev' labeled='yes'``ceremony=yes`
tag `0.1.0` created on the merge commit (verified equal to the PR's merge
SHA), release `0.1.0` published with the fixture changelog section —
verbatim — as its body, and main re-armed to `0.1.1-dev` by the run itself.
The GITHUB_TOKEN tag create and bump push fired **no** second run
(anti-recursion held: the run list gained nothing after the merge run).
**(b) Mislabeled ordinary PR.** README-only PR wearing the `release` label.
Green: `NOTICE: the version '0.1.0-dev' is -dev and unchanged by this PR —
release-flow work under the release label, not a ceremony. Nothing to
publish.` No tag, no release.
**(c) Bare-version PR without the label.** The ceremony's two edits, label
deliberately absent. Red at decide: `the version transitioned ('0.1.0-dev'
-> '0.1.0') but no merged, release-labeled PR is behind this commit — a
release is a labeled ceremony PR, not a bare push — creating nothing.` No
tag, no release; main reverted to the armed state afterwards (the revert
push itself ran green as a no-op, as it should).
**(d) Re-run of the completed ceremony.** Re-ran (a)'s run. Red at the
nothing-may-exist assert: `tag '0.1.0' already exists — this release
already happened, or a manual tag won the race; refusing to re-release,
creating nothing.` Release count still exactly one.
**(e) Tag door.** Branch with `VERSION` `0.2.0` and its stamped section;
manual `0.2.0` tag pushed at its head (never merged to main). The tag door
published release `0.2.0` with that section as its body; the merge door
correctly skipped. Main untouched: `VERSION` stayed `0.1.1-dev` — the
fallback does not rewrite main.
**(f) Mismatched tag.** Tag `9.9.9` pushed at main (tree version
`0.1.1-dev`). Red: `tag '9.9.9' does not match the tree's version
'0.1.1-dev' — creating nothing.` No release, and the operator-facing
remediation text printed as designed.
**(g) Labels bootstrap from nothing** (moved into the drill by triage on
#11 — ceremony's own taxonomy already exists, so the scratch repo is the
only honest place left to exercise the path every fresh consumer hits
first). `workflow_dispatch` of the scratch labels caller: the reconcile job
took the consumer path (`.ceremony-src` fetched at the candidate SHA),
`bootstrap=yes`, and created the full taxonomy — state, blocker,
work-queue, `release` — plus the consumer-owned `scope:fixture` row from
`labels.conf`, on a repo that had only GitHub's defaults. Subsequent
PR-event runs reconciled without re-upserting, as documented.
## Failures
None. Six probes plus (g) behaved exactly as specified, and every refusal
path was checked for droppings — no tag and no release exists that a
refusal created.
