Reviewed f3a53201.

| Round 18 finding | Disposition | Assessment | |---|---|---| | P2: lifecycle property cannot exercise removal during relocation | Resolved | Replacement and release events now exercise blocked cleanup followed by a crash. Recovery distinguishes participating boxes from excluded boxes and checks that excluded boxes never reopen. | | P2: hash-choice test does not assert the hash winner | Resolved | The test independently calculates SHA-256 winners for two hostnames choosing opposite boxes and checks both results. |

No new findings. Rulings 1–27 are accepted. Stage B contracts are complete. L21 remains open, with recovery refusing a nonempty database whose pinned manifest lacks its key.

All 12 embedded patches pass git apply --check; all 47 Go blocks parse with gofmt. Compilation, runtime tests and mutations were not independently reproduced in this read-only workspace.
