Why: Success-shaped receipts and caller-writable history must not authorize apply/admit without controller-originated provenance.
Evidence: Fabricated, unsigned, tampered-history, and moved-ref tests were RED before HMAC binding; 52 controller/history/admission tests now pass.
Impact: Stores a local 0600 attestation key, signs successful history including transport commit SHA, and verifies it before apply/admit.

Why: Safe routing must not retry unproven cleanup, ignore worker fail-stop terminals, or lose out-of-scope rename sources.
Evidence: New tests were RED for each Review finding; 44 controller and admission tests now pass with diff-check clean.
Impact: Tightens safety classification and path inventory only; routing order and provenance contract remain unchanged.

Why: Implementation changes must be mechanically tied to a successful CLI transport instead of relying on agents to follow prose.
Evidence: Admission tests went RED without apply/admit; 10 admission, 41 agent-exec, and 62 task tests now pass with exact staged-content matching.
Impact: Adds validated transport fast-forwarding and rejects unproven implementation commits while exempting task cards and approved plan/spec paths.
