## Verdict
**OKAY**

## Summary
Pass-3 delta-only counter-review confirms that Revision 3 resolves the sole remaining risk-policy governance comment without regressing Revision 2's approved behavior or scope. The authority, path, schema, verifier, and digest correction is internally coherent, matches the repository's customer/runtime authority boundaries, and preserves fail-closed evaluation, activation, and delivery behavior.

## Claims
- The new artifact uses the registered customer-private `CustomerRuntime.nutrition_plans_root`, which the runtime derives from the customer root (`customer_coaching.py:422-445`), and uses a distinct `dual-coach-risk-policy.json` rather than the existing general adaptive `policy.json` (`adaptive_nutrition.py:1463-1465`).
- The approving identity remains the canonical `CustomerRegistry.owner` full Telegram address (`customer_coaching.py:463-465`), consistent with the runbook distinction between review ingress and lifecycle/audit owner (`PILOT_RUNBOOK.md:12-15`, `HANDOFF.md:49-51`).
- The selected live pins are existing authority concepts: current registration authority derives owner, registry, activation-receipt, and authority digests from the committed runtime registry/activation journal (`customer_admin.py:1685-1722`).
- Revision 3 defines an exact document key set, canonical policy digest, non-circular complete-document digest excluding `document_digest`, sole no-caller-path verifier, live-pin equality, and re-verification before dependent append/reservation.
- All verification failures remain explicit and fail closed to the one held, deduped `risk_evidence_unavailable` representation, with no normal evaluation, activation, delivery, provider call, or fallback/default.

## Analysis
### Pass-3 delta
The delta is limited to the pass-2 Architect governance comment. It names one durable customer-scoped path, separates the risk document from the established general policy artifact, seals the schema and both digest preimages, restricts approval to a typed owner-only locked boundary, and names the sole loader/verifier. Revision 2's six-band normalization, inclusive threshold, overrides, candidate preimage, lifecycle authority, reminder, host, and delivery contracts remain unchanged.

### Regression check
The correction does not create a path-authority conflict: `nutrition_plans_root` is already the registered per-customer adaptive storage boundary, while the new filename avoids collision with the existing `policy.json`. It does not conflate Topic-59 authentication with owner authority. The document digest is implementable because its preimage excludes only itself, while `policy_digest` independently pins the behavioral table. Re-verification immediately before dependent transitions closes stale-policy races rather than adding a fallback path.

The unavailable-policy branch is intentionally narrow and evidence-preserving. It retains the previously approved held-candidate behavior and explicitly forbids silent defaults, normal score evaluation, activation, delivery, and provider calls. No root-cause-hiding workaround is introduced.

### Ratchet and consensus
Under pass-3 delta-only review, the prior Critic verdict is already `OKAY`; there is no unresolved carryover blocker and no novelty-justified new blocker. Verdict monotonicity therefore preserves `OKAY`. The current-pass Architect is `CLEAR` / `APPROVE`, so this `OKAY` completes the stated review join gate for stage 3.

## Root Cause
Revision 2 fixed executable risk behavior but left custody and approval governance as implementation-handoff detail. Revision 3 closes that gap by binding creation, storage, approval, verification, and consumption to one customer-scoped authority chain with canonical digest and live-pin checks.

## Findings
None.

## Recommendations
Proceed with the Revision 3 plan as written. Do not broaden the planning scope or alter the preserved Revision 2 contracts.

## Architectural Status
`CLEAR`

## Code Review Recommendation
`APPROVE`

## Decision
`OKAY`

## Consensus status
Review join gate complete for stage 3: Architect `CLEAR` / `APPROVE`; Critic `OKAY`.

## Tradeoffs
The owner-approved per-customer artifact adds a locked write and repeated verification cost, but prevents evaluator self-approval, cross-customer substitution, stale-policy release, and silent fallback. A shared/default artifact is operationally simpler but violates the established authority boundary and remains correctly rejected.

Verification: planning-only delta counter-review. Per assignment, no implementation or tests were run.
