+> **2026-09-24 night — v0.269.0 + v0.269.1. Fleet floor 0.269.1 (MinAgent 0.131.0; needs hub v0.123.0).**
+> `backup.RestoreTier2Whole` (`tier2_whole.go`, decision 26): `mergeRestoreFiles` by the four file rules
+> (never delete; never an older file over a newer one; bring back missing; an older differing live file kept
+> beside as `.felhom-<UTC>`), then `RestoreFromRecoveryUnitAtWith(AcceptMissingFiles)` from the MIRROR; refuses
+> before anything moves (not a file app / no proven openable mirror / < 2 GB). `sameDevice` fails CLOSED (R-668).
+> Decision 27: `RemoveKeepsDataOnly` → 409 `err.stacks.remove_keep_data_while_support`; `keep_data_only` on
+> hdd-data. Decision 28/29: `stacks.ObserveUnhealthy` (RestartCount delta ≥ 6 in 10 min, OOM ≥ 20 in 30 min)
+> → `stopUnhealthyApps` → `HoldUnhealthy` (`unhealthy_stop`, trip 2 within 24 h) → `app_stopped_unhealthy`;
+> Start lifts it. R-664/R-665: `entry.NewMeta` = the step's own `.felhom.yml`. §6.4 part 6 box half:
+> `stacks/digest.go` — `RenderWithLadderDigests` for update + fresh install; **`CarryDigests` for an installed
+> app's sync (v0.269.1, decision 30)**. Open next: R-669 (applied-meta after hold + restore), R-679/R-680 +
+> part 7 (the update leg, `09` §6.4.2), R-681/R-682 (interrupted install/remove). Record:
+> `felhom.eu/documentation/audits/DRILL-night-2026-09-24.md`.
