+> **2026-06-13 — v0.57.0 UI fixes (Part A of the UI-fixes/storage-spike spec):**
+> - A1: fixed the RIGHT storage list — `#host-storage-bars` (the JS-filled, agent-PVE-storage list:
+>   `local`/`local-lvm`/`felhom-pbs`/`felhom-usb`), which reordered on every poll. Now
+>   `enrichHostStorageTargets` sorts `/api/host-metrics` server-side + adds friendly Hungarian
+>   labels/purpose. Display-only — PVE storage ids never renamed. (v0.56.0's 4C had sorted the OTHER,
+>   server-rendered user-data list.)
+> - A2: per-app Tier-2 config panel at `GET/POST /stacks/{name}/backup`; the dead-end "Beállítás" button
+>   (was → deploy page) is repointed there. Pin a target drive / toggle Tier 2 off; prefs
+>   (`UserDisabled`/`PreferredTarget`) persist on `CrossDriveBackup` and survive the runner's status
+>   writes (`withTier2Prefs`). Always visible incl. single-SSD + non-HDD (PBS-context) apps.
+> - Part B (storage OS/data split spike) = build-nothing; findings → `felhom-agent/REPORT-storage-split-spike.md`.
+> - Live-validated on guest 9201; build/deploy = golden bootstrap (`/etc/felhom-controller-image` + restart `felhom-controller-bootstrap.service`).

 > **2026-06-13 — v0.56.0 Phase 4: FileBrowser scoping + UI polish (SLICE COMPLETE):**
 > - 4A: FileBrowser bind scoped to `<drive>/appdata` (recovery units + Tier 2 copies under `backups/`
 >   NOT mounted → customer can't browse/delete the restore source). 4B: deploy storage step states
