Reviewed `40da09b2`.

| Round 15 finding | Disposition | Assessment |
|---|---|---|
| 1: Missing receipt after P opens does not cause `stuck` | Resolved | `VerifyReceipt` compares the durable receipt exactly; the participant marks a missing or changed receipt `stuck` before another admission. Tests cover receipt loss, restart and preservation of post-admission changes. Stage B assigns the production provider and tests. |
| 2: Restart repairs cleanup faults in the lifecycle property | Resolved | The crash event preserves faults and durable records, prevents dead-generation cleanup from completing, and separates recovery. Invariant (h) checks record retention and executable-update denial. |

**No new findings.** I accept rulings 1–24. Stage B contracts retain the prior obligations, owners and named tests.

All 12 embedded patches pass `git apply --check`; all 43 complete Go blocks parse with `gofmt`. Compilation, runtime tests and mutation results were not independently reproduced in this read-only session.
