The controller assumed an app's HDD appdata dir is always appdata/<stackName>.
paperless-ngx writes appdata/paperless (stack paperless-ngx), so every consumer
keying by stack name silently missed it via a stat-and-skip. One canonical
resolver appbackup.AppDataDirNames derives the real dir name(s) from the app's
compose ${HDD_PATH} binds; all consumers use it.
- F-S2 (tier-2): RunTier2 mirrors the resolved appdata/<name> (paperless docs
got NO tier-2 copy before). Tier2Info size + RestoreTier2Files live dir use it.
WARN when a declared appdata dir is absent. New tier2Mirror seam.
- F-S3 (migrate, NEW): all six per-app appdata legs (collision/size/copy/verify/
cleanup/skip-set) now loop resolved names. scope="app" migration of paperless
previously copied nothing and left an empty media dir (scope="all" was saved by
the merge walk). WARN on missing declared dir in the copy leg.
- Multi-dir (N>1) refusal: tier-2 backup/info/restore refuse loudly (Hungarian);
migrate supports N. No catalog app hits it today; lifted by Task 3.
- Display: storage page sums resolved dirs.
- Truth repair: the v0.130.0 "tier-2 copies the namespace wholesale" claim is
false; corrected in CHANGELOG + main.go export-adapter comment.
+9 tests; red-proofs RP-1..RP-5 all confirmed. Controller-only, no agent/hub
coupling. Task 1 of the backup-classification-redesign arc.

agentapi.Decommission + handleStorageDecommission (migrate-all-or-none, Change 2):
migrate-then-decommission via the migration done-hook, or decommission-anyway (stop
apps, keep HDD_PATH). 'Hiányzó tárhely' badge on dashboard/stacks/app card when an
app's drive is decommissioned/disconnected/absent. Change 4: registerStoragePath
clears the decommissioned marker on re-enroll (ClearDecommissioned had no callers).
Non-hollow tests incl. mutation-proven Change-4 companion.

internal/stacks/migrate.go: crash-safe, resumable namespace migration over the
controller's /mnt RW mount. Two entry points (whole-namespace + per-app) share one
journaled pipeline: validate -> stop -> copy (rsync -a --checksum, additive; conflict-
merge walk for non-app content) -> verify -> flip+redeploy (RedeployFromEnv) -> cleanup.
CLEANUP (the only destructive step) is gated on all units verified AND all apps
redeployed. Single-flight; mutual exclusion with the backup orchestrator (Change 3).
Non-hollow tests incl. mutation-proven collision + cleanup-gate companions.
