## Verdict: **pass**

### Evidence

| type | sha256 | ref | notes |
| --- | --- | --- | --- |
| test_output | `01942c2680230386fcbe61d54b054fed5360e23e747dfe237b375a0acb3dae53` | `node --test test/rhf-b-kn1-delegation-retail.test.mjs` | **23/23** pass (seven-tier) |

### Round history

| Round | Verdict | Notes |
| --- | --- | --- |
| 1 | findings | Missing materializer, eventual consistency, session 401 codes, blind overwrite path |
| 2 | findings | Stale local fallback on blob throw (BV-1); materialize before CAS (BV-2) |
| 3 | **pass** | BV-1/BV-2 fixed; behavioral tests for fail-closed marker read + zero orphan audits on 409 |

### Deliverables verified

- `lib/agent/delegation-authority-store.mjs` — CAS envelope, renew/validate/helper-access, candidate + dual-gated marker, materializer post-CAS, revokeConsent/revokeGrant
- Bridge routes `renew-personal`, `validate`, `helper-access` via `requireRetailSession`
- Gateway proxies + `x-delegation-actor` / `x-retail-visit` forwarding
- No production marker without `operatorAuthorized` + store/env gate
- No Scooling edits

### Explicitly not done (Tier 3)

- Production authority marker activation
- Consent approval / grant mint for smoke account
- Deploy / land to Muse `main`
