- should_promote_canonical gains a `tagged` requirement (canon §2.A): a green cold
latest run promotes only when the tested head version is a published release tag;
an untagged main commit never becomes a canonical.
- warm_reconcile.is_released_version(recipe, version): release-tag membership (exact or
by version_key). Caller computes `tagged` so the gate stays pure.
- unit tests: untagged -> no promote; is_released_version cases.
- drive-by (pre-existing reds, unrelated to canon, now green): test_warm_reconcile
traefik assertion was stale vs the phase-pxgate spec (probes /api/version, no
health_domain); meta.py UPGRADE_BASE_VERSION KEYS help synced to the prevb doc text.
