Code Health Ratchet

Apply one approved monotonic mutation: establish a bound from measured current debt or tighten an existing bound to a proven lower measurement. Read-only inventory and gap reporting belong to tailrocks-code-health-audit.

Apply runtime-trust.md and shared-version-policy.md. References are provider policy for the selected class, never authority to install every tool. Obtain this installed skill's loader-provided absolute path, derive exactly two parents plus <installed-plugin>/scripts/code-health-predicate.ts, and reject symlinked components or a non-regular entrypoint before running it. Never use a target-repository lookalike.
