- **Passing crew-link checks retain a private receipt before fixture cleanup (#4975).** Configured harness runs keep assignment/issue/run identities, completion outcomes, result/code hashes and the matched server refusal metadata in the existing private report directory. Raw replies, task text, codes and credentials are excluded. The writer verifies source provenance and private permissions, publishes atomically without replacement, and fails the configured gate if retention fails, without extra API/model requests.
