The artifact now has one durable customer-private location and exact schema, one canonical approving authority, and one verifier with canonical digest and live-pin gates before evaluation and dependent activation/delivery transitions; no blocker remains. ## Claims - The sole authoritative artifact is pinned to `/dual-coach-risk-policy.json`, resolving concretely to the registered per-customer private nutrition-plans root; copies, defaults, gateway configuration, event payloads, cards, and sessions are explicitly non-authoritative (revision lines 17 and 27). - The document has an exact `dual_coach_risk_policy_v1` key contract, exact `dual-coach-risk-v1` identity, canonical `policy_digest`, canonical complete-document `document_digest`, customer and authority pins, and the unchanged fixed behavioral policy (revision line 32). - The sole approver is the refreshed `CustomerRegistry.owner` full `(user_id, chat_id, topic_id)` triple through a typed, authority-lock-guarded write boundary; Topic-59 ingress, evaluator, gateway, scheduler, and candidate producer cannot approve, substitute, or relocate it (revision lines 28 and 33). - `load_verified_dual_coach_risk_policy(runtime)` is the sole loader/verifier. It supplies the path itself, verifies private regular-file/no-symlink custody, exact schema/table/digests/approval/customer binding and freshly loaded live pins, and is required before normalization and immediately before dependent activation or delivery-adjacent transitions (revision lines 27, 29, and 34). - Every missing, stale, unauthorized, relocated, or digest-mismatched case fails closed to one held, deduped `risk_evidence_unavailable` review candidate and forbids normal evaluation, activation, delivery, provider calls, and fallback/default selection (revision lines 35 and 41–47). ## Analysis ### Spec compliance The pass-3 delta is confined to the prior risk-policy custody finding. It preserves Revision 2's policy table, threshold, overrides, missing-evidence semantics, candidate identity, compatibility, ledger ownership, schedule confirmation, reminder, activation, and delivery contracts while making governance executable. ### Prior finding resolution The prior MEDIUM finding requested four concrete pins: authoritative owner, durable artifact path/schema, approving authority, and a verifier/digest boundary. Revision 3 names the canonical registry owner, fixes a registered customer-private path and sealed schema, restricts approval to a typed locked owner boundary, and makes the sole verifier's dual canonical digest plus live-pin checks mandatory both before evaluation and immediately before dependent state transitions. The finding is fully resolved. ### Ratchet application This pass reviews only Revision 3's governance delta and the resolution of the pass-2 finding. No carryover blocker remains, no novel blocker is introduced, and monotonicity permits the prior `WATCH` / `COMMENT` result to improve to `CLEAR` / `APPROVE`. ## Root Cause Revision 2 specified deterministic risk behavior but not authoritative custody. Revision 3 closes that governance gap by binding policy creation, storage, approval, verification, and consumption to one customer-scoped authority chain and failing closed on every contradiction. ## Findings None. ## Recommendations 1. Proceed with implementation against the exact Revision 3 custody and verifier contract. 2. Preserve all Revision 2 contracts unchanged, as Revision 3 requires; no further planning expansion is warranted. ## Architectural Status `CLEAR` ## Code Review Recommendation `APPROVE` ## Tradeoffs - The selected per-customer owner-approved artifact adds an explicit locked write and repeated verification cost, but prevents evaluator self-approval, cross-customer substitution, stale-policy activation, and silent fallback. - A package default or shared policy file would be simpler operationally but violates the established customer authority boundary and is correctly rejected. Verification: planning-only delta review. The revision receipt in the active RALPLAN index matches the assignment path and SHA. No implementation, tests, formatters, fixtures, migration, activation, or provider actions were run.
