07 Writer Blocked Audit

Verdict WRITER_BYPASS_RISK. No new writer path and no permit today. But writer references no plan/tier/signoff/readiness v3; enforcement contract is documentary with every enforced_in_writer=false; writer/procedure remain PUBLIC EXECUTE; an old-style permit can reach old path; writer-blocked guard observes current state but does not block execution. Writer is idle, not structurally blocked until 2.6B/C.
