# STATUS — phase `canon` (canonical sweep, make it real)

## DONE

Gate: M1 PASS (Adversary 3bdd5d1, no VETO). **M2 PASS (Adversary 8149a2c @ 16:14Z, no VETO).**
Both milestones fresh-Adversary-verified; §5 Definition of Done fully cold-verified; no standing VETO →
phase `canon` complete. The canonical sweep is real and proven end-to-end (real non-hollow timer fire
promoted 16 canonicals, determinism 2nd-sweep no-op, tagged-promote gate both ways, samever orthogonal,
all recipes enrolled, UPGRADE_BASE_VERSION retired, AI-free runtime). DEFECT-1/2/3 all closed.

WHAT/HOW/EXPECTED/WHERE for the Adversary. Reasoning lives in JOURNAL-canon.md.

## Phase summary
Make the canonical sweep actually promote canonicals end-to-end (it was hollow), add the mirror-sync +
new-release-tag trigger + tagged-promote gate, enroll all recipes, make the timer weekly, prove it in
real CI. DoD = §5 of `cc-ci-plan/plan-phase-canon-canonical-sweep.md`.

## M1 — PASS (Adversary 3bdd5d1, no VETO)
Machinery proven locally: tagged-promote gate (untagged never promotes), release-tag trigger
(version-keyed not commit-keyed), faithful mirror-sync, all-recipes-enrolled, hollow-sweep root-cause
fix, weekly timer — all cold-verified. See REVIEW-canon.md M1 verdict (07:12Z).

# M2 CLAIM — proven end-to-end in real CI

All M2 code committed+pushed; deployed to `/etc/cc-ci` (HEAD contains every fix). Enrolled = **20**
(keycloak de-enrolled exception, DECISIONS). The authoritative end-to-end evidence is a REAL timer fire
under Drone-parity env + an immediate determinism re-sweep. NO AI at runtime (pure script + systemd timer).

### M2.1 deploy — DONE
`git -C /etc/cc-ci pull` + `nixos-rebuild switch --flake 'git+file:///etc/cc-ci?submodules=1#cc-ci-hetzner'`
(Result=success). Deployed runner = the checkout WITH `tests/` (hollow-sweep fixed).
- HOW: `ssh cc-ci 'systemctl cat nightly-sweep.timer | grep OnCalendar'` → `Sun *-*-* 03:00:00`
  (weekly, §2.F); `ssh cc-ci 'git -C /etc/cc-ci rev-parse HEAD'` contains the parity fix 2c61f2f
  (`merge-base --is-ancestor` ✓).
- HOST PARITY (DEFECT-3 fix): `nightly-sweep` ExecStart prepends host system PATH
  `/run/current-system/sw/bin:/run/wrappers/bin` — byte-matches `drone-runner-exec.service`
  `Environment="PATH=…"`. `ssh cc-ci 'ls /run/current-system/sw/bin/git-lfs'` present → the timer
  sweep validates recipes in the SAME env as Drone CI.

### M2.2 + M2.5 — REAL (non-hollow) TIMER FIRE, full sweep, under production/Drone-parity env — DONE
The deployed `nightly-sweep.service` was fired (real systemd, not manual): active 13:01:01Z →
**completed 14:37:22Z, `Result=success`, `ExecMainStatus=0`, single serial** (no second sweep/
run_recipe_ci proc). This is BOTH the authoritative M2.2 full-sweep evidence AND the M2.5 real-fire
proof (the prior hollow timer logged `enrolled canonicals = []`; this one ran the 20-recipe job and
ADVANCED a canonical).
- HOW: `ssh cc-ci 'journalctl -u nightly-sweep.service --since "2026-06-17 13:00" | grep -E "sweep: |FULL SWEEP done|Result="'`.
- EXPECTED/OBSERVED per-recipe summary:
  - **custom-html: PASS (promoted 1.13.0+1.31.1)** — a REAL non-hollow timer ADVANCE `1.11.0 → 1.13.0`
    in production env (also the M2.6 constructed older→new advance, see below).
  - **14 SKIP no-new-version**: cryptpad, custom-html-tiny, drone, ghost, hedgedoc, immich,
    lasuite-{docs,drive,meet}, mailu, matrix-synapse, n8n, plausible, uptime-kuma.
  - **6 documented exceptions** (all in DECISIONS, none silent): gitea (GREEN-BUT-PROMOTE-FAILED, cold
    green via lfs PASS, app.ini warm-advance exception, 3.5.3 kept); bluesky-pds (GREEN-BUT-PROMOTE-FAILED,
    warm-routing); discourse/mattermost-lts/mumble (genuine reds, canonical unchanged).
- CANONICALS ON DISK (16 promoted): `ssh cc-ci 'for f in /var/lib/ci-warm/*/canonical.json; do echo
  "$f:"; cat "$f"; echo; done'` → cryptpad, custom-html(1.13.0+1.31.1), custom-html-tiny, drone(1.9.0
  +2.26.0), ghost, gitea(3.5.3+1.24.2-rootless, known-good kept), hedgedoc, immich, lasuite-{docs,drive,
  meet}, mailu, matrix-synapse, n8n, plausible, uptime-kuma. Each `commit` == the tested release tag's
  commit (re-derive: `git -C ~/.abra/recipes/<r> rev-list -n1 <version>` == canonical.json `commit`).
- REDS LEFT INTACT: discourse/mattermost-lts/mumble have NO canonical (or unchanged) — never
  force-promoted. bluesky-pds no canonical (warm-routing). gitea kept 3.5.3 (advance failed safely).

### M2.3 — DETERMINISM run-twice → promoted-at-latest SKIP — DONE (clean serial 2nd sweep, COMPLETED)
A clean single-serial 2nd sweep ran **14:41:16Z → 16:05:38Z** (started AFTER the production fire
completed 14:37:22Z → NO overlap; single proc pid 2248547, no concurrent sweep/run_recipe_ci; clean
structured exit with a final per-recipe summary block, no traceback). It demonstrates the operative
no-op (DECISIONS M2.3 framing): **no promoted-at-latest recipe re-runs; only documented exceptions RUN.**
- HOW (Adversary): `ssh cc-ci 'journalctl -t cc-ci-nightly-sweep --since "2026-06-17 14:41" | grep -E
  "sweep: [a-z].* (SKIP|RUN|rc=)"'` — and independently re-derive: for each promoted-at-latest recipe
  `sweep_decision(latest_tag, canon_version)` = `skip no-new-version` (latest tag == canonical version);
  for gitea/reds = run. The trigger is pure + version-keyed (verified M1) → deterministic by construction.
- EXPECTED/OBSERVED final summary (`SKIP — no-new-version` count = **15**):
  - **15 promoted-at-latest → `SKIP no-new-version`** (incl. **custom-html 1.13.0**, which had just
    been ADVANCED in the production fire → now skips = the central determinism proof: cryptpad,
    custom-html, custom-html-tiny, drone, ghost, hedgedoc, immich, lasuite-{docs,drive,meet}, mailu,
    matrix-synapse, n8n, plausible, uptime-kuma). ZERO needless CI reruns of good-current recipes.
  - **gitea → RUN** (new release 3.6.0 > canonical 3.5.3 → deterministically retries the documented
    advance exception → GREEN-BUT-PROMOTE-FAILED, 3.5.3 kept). Correct: keeps offering to advance.
  - **bluesky-pds (GREEN-BUT-PROMOTE-FAILED), discourse (rc=142), mattermost-lts (rc=1), mumble (rc=1)
    → RUN** (no known-good canonical to protect → correctly re-tested; all 4 documented exceptions).
  - Total = 20 enrolled = 15 SKIP + gitea + 4 reds. Deviation from the literal "skip EVERY recipe"
    ideal (= all-promoted) is honestly flagged: the 5 non-skips are exactly the documented exceptions
    (DECISIONS M2.3 framing), and no test was weakened to force a promote (guardrail).

### M2.4 — tagged-promote proof (untagged green ⇒ NO promote; tagged green ⇒ promote) — DONE
- TAGGED → PROMOTE: proof-A (`/root/canon-verify/_proofA.log`) cold-ran custom-html on tag
  `1.13.0+1.31.1` → canonical.json written with `commit=df2e273…` == `git rev-list -n1 1.13.0+1.31.1`.
  Also live in the production fire (custom-html advance) + every promoted recipe (commit==tag-commit).
- UNTAGGED → NO PROMOTE: proof-C (`/root/canon-verify/_proofC.log`) staged an untagged head
  (`1.13.1+1.31.1`, confirmed NOT a release tag) and cold-ran GREEN → `grep -c "WC5 promote-on-green-cold"
  _proofC.log` = 0; canonical.json unchanged. Unit: `test_no_promote_when_untagged`.

### M2.6 — samever orthogonality (step-back NEVER fires in the sweep) — DONE
- Path (2) new-tag → canonical(older)→new, real delta, promote: **custom-html advanced 1.11.0 → 1.13.0
  in the production timer fire** (a constructed-then-live older→new advance that PROMOTED healthy) — the
  warm-ADVANCE machinery works end-to-end. Also gitea fired the trigger live (RUN on 3.6.0 > canonical
  3.5.3) — the trigger half of path (2) (its promote is the documented recipe exception).
- Path (1) no-new-tag → SKIP: the 15 SKIP-no-new-version recipes (latest tag == canonical) — no
  upgrade-tier run, no promote, even where `main` has untagged commits (trigger is version-keyed).
- STEP-BACK NEVER FIRES: by construction the sweep only RUNs when latest tag > canonical version, so
  the upgrade base (older canonical) is strictly older than the version under test → `samever`'s
  same-version step-back cannot trigger. samever's same-version behaviour is owned/proven by the
  samever phase on the PR path (M1 1310a95 / M2 199f5b6). HOW: read `nightly_sweep.sweep()` — RUN
  branch is gated on `sweep_decision == run` which requires `version_key(latest) > version_key(canon)`.

### M2.7 — warm-volume disk budget — DONE (DECISIONS 009bc60)
`/` 150G total, **38G free (74% used)**; `du -sh /var/lib/ci-warm` = 1.1G; docker Local Volumes 2.024GB
(929MB reclaimable). 16 retained canonicals fit with ample headroom at the full 20-enrolled set. WC8
`ci-docker-prune` bounds residue. No recipe dropped for disk; all-enrolled sustainable.

### M2.8 — UPGRADE_BASE_VERSION retired — DONE (f611dda, 83c183d)
plausible promoted its canonical → the dynamic upgrade base now steps back to the newest published
release strictly older than latest (= `3.0.1+v2.0.0`, the correct base, avoiding the broken
clickhouse-404 `3.0.0`) WITHOUT the pin. Pin removed from `tests/plausible/recipe_meta.py`; meta KEY
removed (`runner/harness/meta.py` 15→14); resolver override branch removed (`run_recipe_ci.py`); docs
(`recipe-customization.md`, `testing.md`) + unit tests (`test_meta.py`, `test_upgrade_base.py`) updated;
bluesky-pds comment now points to the dynamic base. §2.G GATE (keep-if-broken) does NOT apply — plausible
resolves base 3.0.1+v2.0.0 dynamically and passes.
- HOW: `grep -rn UPGRADE_BASE_VERSION runner/ tests/ docs/` (excl. machine-docs) → only explanatory
  comments, no live key/branch; `cc-ci-run -m pytest tests/unit/` → all pass.

### NO AI at runtime — DONE
grep `nightly_sweep.py` / `warm_reconcile.py` / `recipe-mirror-sync.sh` for anthropic|claude|openai|llm|
gpt → zero calls (only one code comment). Pure script + systemd timer.

## Build hashes / fingerprints
- HEAD (Builder clone) = `009bc60`; `/etc/cc-ci` deployed HEAD contains 2c61f2f (parity) — all M2 fixes.
- custom-html canonical advanced: `1.11.0 → 1.13.0+1.31.1`, commit `df2e273…`.
- gitea canonical kept at `3.5.3+1.24.2-rootless` (3.6.0 advance is documented exception).

## Documented exceptions (DECISIONS, none silent)
keycloak (de-enrolled, OIDC-provider domain collision); gitea 3.6.0 warm-advance (app.ini read-only);
discourse (upstream 0.8.1 compose invalid: sidekiq→undefined service); mattermost-lts (test_restore red);
mumble (test_handshake red); bluesky-pds (warm-domain routing 000). All recorded with reasons.
