# REPORT — v0.124.0: backups IA restructure (four sub-pages, Felhom-offsite status card, .fab browser download)

**Date:** 2026-07-13 · **Version:** controller v0.124.0 (from v0.123.0) · **MinAgent:** 0.81.0 (UNCHANGED) · **Floor:** untouched (rides the next train) · Controller-only.

## What shipped (commits `0ece2ba`, `aa967fb`, `753cd83`)

1. **IA split** — `/backups` (Áttekintés), `/backups/remote` (Távoli mentés), `/backups/apps`
   (Alkalmazások), `/backups/restore` (Visszaállítás), sidebar children (Tárhely pattern).
   Sections MOVED verbatim from the v0.123.0 page — the committed one-shot
   `scripts/backups_split_move_check.py` verifies all 15 blocks against baseline `df7ad37`
   (whitespace-normalized; the two allowed divergences — tier-3 anchor retarget + the
   restore-to-verify relocation — are encoded explicitly). Shared handler builders extracted
   (`backupsCommonData`/`backupsOffboxData`); flash redirects, tier-3 anchors and the
   tier2-config back-link retargeted per page.
2. **Felhom-offsite status card** — three honest states from local data, display-only by
   construction (no form/button inside the card; unit-enforced). Decision 2 honored: the card
   never changes anything.
3. **.fab browser download** — existing export pipeline + staging dest + guarded streaming exit
   with estimate-first UX, post-stream cleanup and a 1h TTL sweep; per-app sequential batch;
   portability framing everywhere (decision 3). Import stays drive-scan.

## Tests + red-proofs (run → FAIL → restored)

- **Move check red-proof:** one moved block reworded → exit 1 ("1 block(s) rewritten"); restored → 0.
- **Traversal guard red-proof:** guard loosened to raw prefix-matching → `../decoy.fab` came back
  **200 serving the decoy** — the test caught it (got 200, want 400). Restored → green.
- **Round-trip + corruption (data-mutation red-proof):** real `executeExport` → bundle →
  real `executeImport` → byte-identical restored content; a mid-file-corrupted copy is REFUSED
  (job fails, app not started, nothing restored). Integrity = gzip CRC + manifest segment
  validation — there is NO per-file checksum (documented; the spec's "manifest checksum" wording
  adapted to reality).
- Nav/state tests (marker per section, present on exactly one page; `.Page` ids), status-card
  state tests, TTL sweep test (fake mtimes/now). Full green gate + all five template gates green
  per commit.

## §13 live validation

- **Deployed:** 0.124.0 on the drill guest (qm300) AND demo 9201, both healthy.
- **Four-page walk (drill, screenshots in session record):** every moved control clicked once —
  tier-2 Beállítás (+ retargeted back-link), tier-3 toggle (off→on), restore-to-verify from its
  NEW home (`/backups/restore` flash), manual-target form open/close. Old `/backups` bookmark →
  Áttekintés on both boxes; sidebar active states correct.
- **Status card:** state 3 (no card) and state 2 ("Aktív — nincs kijelölt alkalmazás") both
  live-rendered on the drill box; state 1 by unit render test (demo has a managed target — spec
  says do NOT unconfigure).
- **.fab download:** drill ActualBudget — estimate 3.6 KB shown first, bundle 2102 B streamed,
  staging bundle removed (server log). Demo ActualBudget — downloaded to the operator machine,
  sha256-identical after placement on `felhom-usb/exports` (`e2a1233f…` both ends).
- **Supervised import (Viktor GO):** ON DEMO (see finding 2 for why not drill): scan found the
  bundle, manifest read (exported-by 0.124.0), "Importálás kész! Az alkalmazás sikeresen
  visszaállítva.", ActualBudget Up (healthy). **The round-trip surfaced finding 1.**

## FINDINGS (both pre-existing, surfaced by this task's first real containerized round-trip)

1. **(HIGH — data-loss trap) Containerized .fab export ships EMPTY volume data.**
   `exportVolumeData` runs `docker run -v <volDir>:/out alpine tar …` where `<volDir>` is the
   controller-CONTAINER's `os.MkdirTemp` path — the guest's docker daemon resolves it against the
   HOST filesystem, so the tar lands stranded on the guest host (`/tmp/felhom-export-*/…`, found
   with ActualBudget's 66 KB tar in it) and the bundle's `data/volumes` is empty while the
   manifest claims volume data and the export reports SUCCESS. Import then wipes the app's
   volumes and brings it up EMPTY. Affects every golden/bootstrap (containerized) box for
   volume-backed apps; HDD-data apps are unaffected (direct FS copy). Demo's ActualBudget was
   repaired from the stranded tar; both temp dir and staged bundle cleaned. **Fix direction:**
   stage the docker-run output under a host-visible bind (e.g. the controller data volume) or use
   `docker cp`/stdout streaming; plus a post-export assertion that manifest-claimed volume tars
   exist in the bundle (fail LOUD).
2. **(MEDIUM — agent-side, out of this controller-only task) Drive wizard offers zero candidates
   on a legacy-boot PVE.** With LVM root and no ESP mount, every system mount resolves to
   device-mapper, `storage.SystemDisks` finds no raw disk → `sysKnown=false` → `isSystemBacked`
   fail-safes EVERYTHING to system → `ListCandidateDisks` is always empty (drill box; a hot-added
   blank 5G disk stayed invisible). The fail-safe is right to exist but overreaches here — needs
   an agent ruling (e.g. resolve device-mapper parents to their PVs' disks).

## Observations

- **.fab browser-UPLOAD** remains the noted follow-up (import is drive-scan only — downloaded
  bundles return via a drive/share, exactly as exercised here).
- **Combined mega-zip** stays parked (decision; per-app sequential batch shipped instead).
- **appexport packages LIVE state** (fresh config copy + DB dump + live data), NOT the tier-1
  recovery unit — §8's "stale unit" concern is moot; no "futtass előbb mentést" needed.
- The import page's drive-label mojibake ("TÃ˘rhely (felhom-usb)") is the KNOWN open fix-5 item.
- `NoUserDataBackupWarning` is referenced by the per-app section but never set by any handler
  (dead conditional, pre-existing); `DBDumpTotalBytes` was computed but never rendered — dropped
  in the split.
- Drill box left as found: hot-added disk detached + LV removed; ActualBudget re-toggled; demo
  exports dir + stray export temp cleaned.
