Reverses the Phase 4 scope cut: for EXISTING folder/zip audiobooks a
sidecar edit was invisible to everything, including force rescan —
updateAudioBookItem writes only scan-derived fields, and these formats
often have no useful embedded tags, so the sidecar is the only source.
- Change fingerprint gains the manifest compare in both processors:
changed := size differs || track payload differs || manifest drifted.
The ladder runs against the bulk-loaded map entry (stat pairs only,
zero extra queries); NULL stored manifest backfills without
re-extraction (deploy-day rule, same as single-file).
- Manifest-changed applies the once-extracted book metadata to the
editorial columns (updateMediaItemWithMetadata, overrides protected)
and re-runs the playlist hook. The apply runs BEFORE the focused
payload write: the generic update's format-group pass derives mime
from the sentinel (none) and chapters from metadata.ChapterCount
(unset) — the payload write must win (rescanMultiFileAudioBook's
ordering). Track-only changes keep the existing editorial-keep
update; force rescan keeps it too.
- Manifests seeded at multifile create (folder names derive from the
sentinel — the exact representative the extractor reads — via
detectSidecarChangeWithRepresentative, so manifest and extractor can
never disagree; a directory-basename cover is ignored by the
extractor and therefore not tracked).
- Zip parity fixes: the fast path now lifts archive state like the
folder path always did (a returned zip book stayed archived
forever), and the change branch handles the unchanged-archived case.
- Single-file sidecar change path: extract-failure guard — the old
non-nil empty &MediaMetadata{} fallback bypassed the update path's
filename-title guard (preExtracted == nil only) and would blank the
title on a failed extraction; the row is now left untouched and the
manifest refreshed. Empty-success extraction (sidecar removed from a
tag-less book) now passes nil so the create-equivalent chain (tags →
filename) re-derives instead of blanking.
- Multifile changes now count in the scan summary (changedItems);
they were previously uncounted.
Tests: sentinel-name derivation unit pin; folder sidecar edit
(title + collection sync + fresh manifest + steady-state skip),
track-only change keeps editorial, zip sidecar edit + archive
restore, sidecar removal falls back to filename (the wipe-guard's
testable sibling). Full container suite: green except the documented
pre-existing TestAdminCreateUser red.
