R-384. aggregateState returned StateUnhealthy the moment unhealthy > 0, and the R-51 mixed-case block that asks "is a supervised member dead?" sat below it. A two-container app whose database exits goes unhealthy BECAUSE it cannot reach that database - so the symptom the dead database causes was what suppressed the alarm for it. unhealthy is not a down state, so classifyRunStates never marked the app down and app_start_failed never fired. Measured live on demo-hp 2026-08-22: bookstack-db stopped at 21:27:01 and the F-OBS heartbeat printed "0 currently down" throughout. R-51's 18-hour immich failure, back through a different door. Two things moved, and either alone leaves the defect standing: the supervised test is hoisted above the unhealthy/starting/restarting returns, and "some members are up" now counts ANY member not in the down bucket. The old guard was running > 0, which made the R-51 block unreachable in exactly the case it was written for. IsDownState is byte-identical - unhealthy stays excluded, because an unhealthy container is running and folding it in reintroduces the flapping that exclusion exists to stop. No new state was minted. Only the ORDER changed. The priority comment was rewritten because it asserted an ordering the code no longer has. Three subtests in TestAggregateState_UnchangedBranches were AMENDED: they asserted an unhealthy/starting/restarting member beat an exited peer on unless-stopped, which pinned the defect as settled behaviour. They keep their intent with the down member given a benign policy. R-383. The double-failure message said the previous state's backup EXISTS, built from the returned path without asking the filesystem - and a missing file is one of the two ways that rollback fails. undoCopyPhrase now describes the copy from disk: present, partial, missing (still naming where it should be), or never written. Zero-length counts as missing. Test count 1494 -> 1504. Four red-proofs planted, four seen failing; the two halves of R-384 convict independently.
