# 0.4.0 — drill record
Run 2026-07-29 by `codex-bot-andresmgsl` against release PR #207 head
`7c755bcd402ba7f9a38ecd406a025c149c77aa57`.
Where: disposable private repo
`codex-bot-andresmgsl/ceremony-drill-0.4.0`, carrying the
`docs/CONSUMERS.md` release caller and a fragment-mode fixture armed at
`0.4.0-dev`. The fixture had `changelog.d/README.md`, one release fragment,
and a non-blank drill record. The repository is archived, pending the
operator's delete.
## Candidate-ref deviation
The pure consumer path cannot resolve `CEREMONY_SELF_REF: "0.4.0"` before
the candidate creates that tag. No `0.4.0` branch was created in
`heavy-duty/ceremony`. The scratch caller instead used
`codex-bot-andresmgsl/ceremony@drill/0.4.0`, whose parent is PR #207 head
`7c755bcd402ba7f9a38ecd406a025c149c77aa57` and whose only additional
commit rewrites both `CEREMONY_SELF_REF` carriers to that same canonical
candidate SHA. All runtime machinery was therefore fetched from the 0.4.0
candidate tree.
## Probes
| # | probe | run | result |
|---|---|---|---|
| 1 | merge-door ceremony | 30445585532 (attempt 1) | ✅ one `0.4.0` release; tag equals merge commit; main re-armed to `0.4.1-dev` with only `changelog.d/README.md` |
| 2 | mislabeled ordinary PR | 30445473977 | ✅ green NOTICE no-op; no tag or release |
| 3 | bare-version PR without `release` | 30445513860 | ✅ refused at decide; no tag or release |
| 4 | re-run completed ceremony | 30445585532 (attempt 2) | ✅ refused because the tag/release already existed; release count stayed one |
| 5 | manual matching tag | 30445658952 | ✅ `0.5.0` published with its changelog section; main untouched |
| 6 | mismatched tag | 30445684268 | ✅ refused before publication; no `9.9.9` release, and the probe tag was removed afterward |
The merge-door `0.4.0` tag and PR #3 merge commit were both
`2b2d592ffcc5c376e55bd5fcf2dd5ffbdd692d64`. Its release body was exactly:
```text
- Fragment mode is exercised by the 0.4.0 drill.
```
## Setup
The armed fixture was committed before the caller so the first workflow run
had a real parent version to inspect. Installing the caller then produced
green baseline run 30445432039.
After the unlabeled bare-version refusal, its merge commit was reverted to
restore the armed fixture. That setup correction produced green no-op run
30445544068 before the merge-door probe began.
