appbackup's path helpers take a NAMESPACE ROOT. Five call sites passed a bare DRIVE path.
On an enrolled drive the two coincide, so nothing showed; on the system-data fallback they
differ by exactly the felhom-data segment, and the app then bound a directory the off-site
capture set never looked at -- while the run reported ok. Measured live on demo-hp: the app
wrote to /mnt/sys_drive/userdata/media/books, the capture set looked for
/mnt/sys_drive/felhom-data/userdata/media/books.
THE RULE NOW HAS ONE EXPRESSION. appbackup.NamespaceRootFor / IsEnrolledDrive encode the
drive-kind comparison; backup.Manager.namespaceRoot and stacks.Manager.inGuest delegate to
it. There were already TWO copies and they differed -- the backup package's compared without
filepath.Clean, the stacks package's with it, so a trailing slash from config would have
flipped the mode in one and not the other.
Sites routed through it:
- stacks/deploy.go withPathVars -> ${USERDATA_PATH} (the live defect)
- appexport/fabplan.go + export.go (via a new provider method)
- web/handlers.go FileBrowser mounts (latent: the system drive is
deliberately never a registered StoragePath, so this is the identity today)
ComputeFabBuckets now receives the namespace root, which is what ComputeCaptureSet has always
received -- so the export's classified paths and the backup's capture set describe the same
directories by construction instead of by coincidence.
Tests are table-driven over BOTH drive kinds, because this survived by being invisible on the
kind that already worked. Red-proofs observed: restoring the bare-path call fails the
system-drive row with the two paths differing by /felhom-data; inverting the drive-kind
comparison fails every enrolled row.
${IMPORT_PATH} = <system namespace root>/userdata/import — ONE drop-zone per box,
on the system drive, injected at BOTH compose-env builders with NO per-drive
fallback (unresolvable leaves it unset so compose fails loudly rather than
quietly building a second, dead drop-zone).
Third BindRoot (RootImport) + Import list in BackupSpec, extended through
ValidateBackupSpec/ClassifyBinds. Load-bearing: a stale `userdata: import/<app>`
entry against the moved bind would be a WHOLE-BLOCK reject, taking the app's
mandatory hdd classification with it.
Exhaustive-root audit: resolveAbs/structuralGuard/ComputeCaptureSet/
ComputeFabBuckets now take importRoot explicitly (an import bind resolved
against hddPath would name a directory on the wrong drive); unresolvable is
refused loudly into Skipped. GetImportRoot added to both provider interfaces.
Catalog-derived skeleton: UserdataSkeleton() -> UserdataSkeletonCarry() +
BuildUserdataSkeleton(), SORTED. The carry-list makes zero-removals true by
construction (`documents` is in no catalog app but on both boxes) and is the
fresh-box floor. The sort is not tidiness: the naive map-order derivation
measured 20 distinct outputs from 20 identical runs, which with fbNeedsRecreate
is a fleet-wide FileBrowser restart loop.
One authoritative compose parser: ParseComposeUserdataMounts now delegates to
ParseComposeClassifiableBinds. Import root excluded from per-app migration.
Surfaces: FileBrowser /srv/beolvasas source; app-page "Hova tegyem a fajlokat?"
with PathEscape deep links (never QueryEscape) and class-driven copy;
data_paths: annotation with the Fork-3 asymmetry; system-owned beolvasas SMB
share refused server-side at handler AND store, button omitted in template.
Caught on the way: the sharing template's row struct was function-local, so
adding {{if .System}} would have 500'd every share row. ShareRow is now
package-level and the render test uses the handler's own type.
Tests 915 -> 949, all green. MinAgent unchanged.
DeployStack's initial compose-up builds env from deploy values (not stackEnv), so
v0.66.0 missed USERDATA_PATH on first deploy → ${USERDATA_PATH} resolved to '' and
Docker bound a root-owned dir at the container root (found live: radarr /media/movies
was 0:0 755). Shared withUserdataPath injector now used by stackEnv AND
composeExecWithEnv. Regression test included.
