10 No Bypass Proof Audit

Verdict NO_BYPASS_PARTIAL. Current production cannot apply: no signoff/tier/permit and readiness blocked. Proof is not valid end-to-end: writer assertion proves v5/old signoff, treats v6 gates as containment though writer ignores v6, misses public builder/refresh mutation, and does not bind exact plan/collection/tier/signoff/permit/run/writer tuple.
