The catalog README's per-plugin `vX.Y.Z` labels were an UNGUARDED surface:
check-versions validated each plugin's OWN README badge, never the catalog
README's labels, so they drifted (config-audit shown v5.5.0 while pinned to
v5.7.0; voyage v5.1.1 while pinned to v5.6.0) — the doc misstated what
`claude plugin install` actually resolves.
Close the class, same pattern as the ref surface:
- check-versions.mjs: new ERROR rule "catalog README label == catalog ref"
via pure extractCatalogLabel() (matches the /open/<name>) heading, takes the
first `vX.Y.Z`, ignores a trailing lang/flag badge). No legitimate transient
state lets label != ref, so ERROR (not WARN). +5 tests.
- release-plugin.mjs: on --write, bump the README label atomically with the ref
via pure reconcileReadmeLabel() and git add README.md on --commit, so future
releases keep label and ref in lock-step. +4 tests.
- README.md: reconcile the 2 stale labels (config-audit -> v5.7.0,
voyage -> v5.6.0). Gate now 9 OK / 1 WARN / 0 ERROR.
- CLAUDE.md: doctrine updated to document the new gate rule + atomic label bump.
ms-ai-architect stays WARN by decision (1.16.0 is unreleased WIP, never tagged).
