claim(M1): canonical sweep machinery built + live-proven on custom-html

M1 (machinery works locally, each piece proven) — code HEAD d4cc9e4, unit suite 295 passed:
- M1.1 tagged-promote gate + promote-tested-version: live proof-A wrote a fresh canonical
  (commit df2e273 = the tag commit, correcting samever's main-HEAD 2b82eba); live proof-C
  green-untagged → 0 promotes, canonical byte-identical (tagged-gate blocks untagged).
- M1.2 sweep_decision (version-keyed trigger) + vendored faithful recipe-mirror-sync.sh
  (smoke-tested: faithful no-op main/tags push, closed merged-upstream PR #2, left PR #5);
  nightly_sweep rewritten (mirror_sync -> trigger -> run_on_tag). Live SKIP demo on custom-html.
- M1.3 all 21 used-recipes enrolled. M1.4 hollow-sweep fix (CCCI_REPO=/etc/cc-ci). M1.5 weekly timer.
- M1(A) reattach: live proof-B --quick reused the retained volume green; known-good unchanged.

+## Phase canon (2026-06-17) — canonical sweep made real
+
+- **Tagged-promote gate (§2.A).** A canonical only ever advances to a PUBLISHED RELEASE TAG.
+  `should_promote_canonical` requires `tagged` (computed by the caller via
+  `warm_reconcile.is_released_version(recipe, head_version)`); `promote_canonical` records the TESTED
+  `head_version` (the release version actually exercised), NOT a re-derived `latest_version(recipe_tags)`
+  — these can diverge in a manual `RECIPE=<r>` run whose `main` sits on a tag older than the newest
+  published tag. An untagged `main` commit never becomes a canonical.
+- **New-release-tag trigger (§2.D).** The weekly sweep tests a recipe only when its latest release tag
+  is newer (by `warm_reconcile.version_key`) than its canonical version — NOT on new commits. No new
+  tag → SKIP (even if `main` has untagged commits). This gives the run-twice determinism no-op and
+  makes the sweep orthogonal to `samever` (version-under-test always > canonical → no same-version
+  step-back in the sweep).
+- **Mirror-sync is a VENDORED `scripts/recipe-mirror-sync.sh`, not the nix-store
+  recipe-upgrade/open-recipe-pr.sh.** Rationale: open-recipe-pr.sh assumes the recipe clone's `origin`
+  IS coopcloud upstream, but cc-ci's abra recipe clones have inconsistent remotes (origin is variously
+  the mirror / coopcloud / absent). The vendored script pins an explicit coopcloud `upstream` remote
+  by recipe name, syncs main+TAGS (canon's trigger needs upstream tags), closes only merged-upstream
+  PRs, leaves unrelated PRs, and authes via the bot gitea token (self-contained, reproducible — a
+  systemd service must not depend on a per-skill-version nix-store path). Behaviour matches the phase's
+  described `--reconcile-only`: faithful mirror sync, never our own changes.
+- **Hollow-sweep root cause + fix.** The deployed timer ran the nix-STORE runner copy (no `tests/`),
+  so `enrolled_recipes()` resolved `TESTS_DIR` to a missing dir → `[]` → no-op. Fix: the sweep runs
+  from `$CCCI_REPO=/etc/cc-ci` (has runner/ AND tests/); deploys `git -C /etc/cc-ci pull` +
+  nixos-rebuild. Sweep-logic now ships via a checkout pull (no store rebuild needed for logic-only).
+- **All 21 used-recipes enrolled (§2.B); cadence weekly (§2.F).** The enroll set is exactly
+  `cc-ci-plan/used-recipes.md`; test fixtures stay unenrolled.

+## 2026-06-17 — M1 built + live-proven (CLAIMED)
+
+All M1 code landed (HEAD d4cc9e4). Reasoning behind the choices:
+
+- **Tagged-gate computes `tagged` at the call site, not inside the gate** — keeps
+  `should_promote_canonical` pure (the Adversary anti-anchoring + the existing unit-test contract).
+  `is_released_version` lives in warm_reconcile (owns version logic + recipe_tags I/O).
+- **Promote the TESTED version (divergence fix, d4cc9e4):** the Adversary's pre-claim probe flagged
+  that the gate checks `head_version` but promote recorded `latest_version(recipe_tags)`. Live proof-A
+  made this concrete and favourable: the OLD record had commit `2b82eba` (a merge-to-main commit),
+  but the tag `1.13.0+1.31.1` actually points to `df2e273`. Recording the tested version's head_ref
+  now writes the TAG commit — strictly more correct. Sweep path was already safe (head==tag), but the
+  manual `RECIPE=<r>` path needed it.
+- **Why a vendored mirror-sync script, not the nix-store open-recipe-pr.sh:** the recipe clones on
+  cc-ci have INCONSISTENT remotes (n8n: origin=mirror; mumble: origin=coopcloud; ghost/discourse:
+  origin=mirror, no `upstream`). open-recipe-pr.sh assumes origin=coopcloud → would force-sync mirror
+  main to *mirror* main (no-op) for most. The vendored `scripts/recipe-mirror-sync.sh` pins an
+  explicit coopcloud `upstream` remote from the recipe name, syncs main+TAGS (canon needs upstream
+  tags for the trigger), and authes via the bot token (self-contained, not host .git-credentials).
+  Behaviour matches the phase's described open-recipe-pr.sh --reconcile-only (faithful, close
+  merged-upstream PRs, leave unrelated). See DECISIONS.
+- **Why test the TAG via checkout+CCCI_SKIP_FETCH (run_on_tag), not just REF=tag:** REF alone (no SRC)
+  takes fetch_recipe's `abra recipe fetch` branch (ignores REF) AND would set `ref` → should_promote
+  blocks. Staging the tag in the clone + CCCI_SKIP_FETCH makes head=tag with REF empty → promote
+  allowed, and exercises the real "cold on the tagged release" path.
+
+### Live proof evidence (cc-ci, /root/canon-verify @ d4cc9e4)
+- proof-A (promote): canonical.json fresh ts 065027Z, commit df2e273 (=tag commit). Note: because
+  custom-html canonical already == latest, run_on_tag here re-promoted an EQUAL version → the samever
+  step-back fired (base 1.11.0+1.29.0). That is an artifact of bypassing the trigger for the proof;
+  the REAL sweep SKIPs equal-version (sweep_decision), so the step-back never fires in the sweep — to
+  be shown live in M2 (canonical(older)→new tag, base=canonical, no step-back).
+- proof-B (reattach): --quick reattached the retained volume, green (4 tests passed), known-good
+  version+commit UNCHANGED (df2e273); ts re-stamped only by the idle-status write (write_registry
+  stamps ts on every status write) — NOT a promote.
+- proof-C (untagged→no-promote): green cold run (level 5/5) on an untagged head (label 1.13.1+1.31.1)
+  → 0 promote log lines, canonical.json byte-identical before/after. Tagged-gate works live.

+
+**M1.1 — tagged-promote gate (§2.A).** `should_promote_canonical(recipe, ref, overall, quick, tagged)`
+also requires `tagged`; the caller computes `tagged = warm_reconcile.is_released_version(recipe,
+head_version)`; `promote_canonical(recipe, head_ref, version)` records the TESTED `head_version` (a

+    (incl. `test_no_promote_when_untagged`, `test_is_released_version`).
+  - HOW (live PROMOTE): the new code path ran on cc-ci via `nightly_sweep.run_on_tag('custom-html',
+    '1.13.0+1.31.1')` (proof-A). EXPECTED+OBSERVED: `/var/lib/ci-warm/custom-html/canonical.json`

+    = the EXACT commit tag `1.13.0+1.31.1` points to (`git -C ~/.abra/recipes/custom-html rev-list -n1
+    1.13.0+1.31.1`). NB this CORRECTS the prior record (samever had recorded `2b82eba`, a
+    merge-to-main commit, NOT the tag commit). Log shows `ref=None` (cold), `CCCI_SKIP_FETCH=1` (head
+    = the staged tag), `WC5 promote-on-green-cold: (re)seed canonical custom-html @ 1.13.0+1.31.1`.
+  - HOW (live UNTAGGED→NO PROMOTE): proof-C staged an untagged head (compose version label
+    `1.13.1+1.31.1`, confirmed NOT a release tag, image unchanged) and ran a COLD run. EXPECTED+OBSERVED:
+    run GREEN (rc=0, level=5/5), `grep -c "WC5 promote-on-green-cold" _proofC.log` = **0**, and
+    canonical.json version+commit+ts **identical** before/after (`1.13.0+1.31.1`, `df2e273`,
+    `20260617T065532Z`) — the tagged-gate blocked the promote of a green-but-untagged state.
+
+**M1.2 — release-tag trigger + faithful mirror-sync (§2.C/§2.D).**
+  - `warm_reconcile.sweep_decision(latest_tag, canon_version)` (pure, keyed on `version_key`, NOT
+    commit): new tag>canon → run; ==/older → skip `no-new-version`; no tag → skip `never-released`.
+    HOW (unit): `pytest tests/unit/test_warm_reconcile.py -k sweep_decision`. HOW (live SKIP): on
+    cc-ci, custom-html `latest_tag == canonical (1.13.0+1.31.1)` → `sweep_decision` =
+    `('skip','no-new-version (latest release 1.13.0+1.31.1 <= canonical 1.13.0+1.31.1)')`. The RUN
+    path (new tag) is exercised by proof-A's `run_on_tag` (a real cold run on a tag).
+  - `scripts/recipe-mirror-sync.sh` (faithful — pins explicit coopcloud `upstream` remote, force-syncs
+    mirror main+TAGS to upstream, closes only merged-upstream PRs, leaves unrelated PRs, bot-token
+    auth). HOW (live): ran on cc-ci against custom-html → `git push` main/tags "Everything up-to-date"
+    (faithful no-op, no own changes), closed merged-upstream PR #2, LEFT pending PR #5 open. Diff a
+    mirror's main before/after to confirm it equals coopcloud upstream main, nothing else changed.
+  - `nightly_sweep.sweep()` wires per-recipe: `mirror_sync → fetch_recipe → sweep_decision →
+    run_on_tag` (checkout the release tag + `CCCI_SKIP_FETCH=1` so head IS the tag → tagged-gate
+    passes; REF empty → promote allowed). NO AI at runtime (pure script).
+
+**M1.3 — all recipes enrolled (§2.B).** `WARM_CANONICAL=True` in every `tests/<r>/recipe_meta.py` of
+the 21 `cc-ci-plan/used-recipes.md` rows. HOW: `grep -rl 'WARM_CANONICAL = True' tests/*/recipe_meta.py
+| wc -l` → 21; `python3 -c "import sys;sys.path.insert(0,'runner');from harness import canonical;
+print(len(canonical.enrolled_recipes()))"` → 21. Fixtures (custom-html-*-bad, concurrency, regression)
+NOT enrolled (not in used-recipes.md).
+
+**M1.4 — hollow-sweep root-cause fix.** `nix/modules/nightly-sweep.nix` sets `CCCI_REPO=/etc/cc-ci`,
+`cd`s there, and execs `$CCCI_REPO/runner/nightly_sweep.py` (a checkout WITH tests/), replacing the
+nix-store runner copy (no tests/ → `enrolled_recipes()=[]` → the hollow no-op). Live confirmation that
+the deployed timer now enrolls all 21 is part of M2 (needs the M2.1 deploy: `git -C /etc/cc-ci pull` +
