John O'Keefe 7e4c97f639 feat(scanner): fix ABS sidecar series parsing; three-way series mapping; smart genre; language codes; title-derived series
Phase 2a of the metadata overhaul (plan §2.1-2.3, §2.5-2.9).

The headline bug: ABS writes sidecar series as an array of STRINGS
(["The Witcher #3", ...]); the parser only accepted {series, sequence}
OBJECT arrays, so every ABS-matched book silently lost its series (found
live: 9 sidecars, zero series ingested; only folder-structure Malazan
survived). parseSeriesCandidates now normalizes string arrays, object
arrays and Libation plain strings.

Three-way series assignment (plan §2.2):
- primary bibliographic series -> series/series_number columns
- additional real series (Drizzt: Icewind Dale #1 = Legend of Drizzt #4)
  -> alternate_info JSONB, comic-established shape
- ordering constructs ('The Witcher (Reading Order)') -> PlaylistSeries
  candidates; NEVER the series column. Detection is explicit-marker-only
  ((reading order|chronological|publication order|in order|timeline) as
  parenthetical/suffix) — precision over recall; a series merely
  containing 'timeline' mid-name stays a series.

Sequence policy: leading-number extraction ('Book 2' -> 2, '2,
Dramatized Adaptation' -> 2, '1a' -> 1); lossy extractions preserve the
raw text in alternate_info.series_sequence_raw.

Smart genre (deterministic lexicon): compound Audible blobs split
('Epic, Action & Adventure, Military, Sword & Sorcery' -> 4 candidates),
alias-normalized, format noise demoted ('Audiobook' never wins),
most-specific canonical genre takes the genre column, all candidates
stay in tags.

Language: display names normalize to ISO 639-1 on ingest; ROOT-CAUSED
the update-path drop — CreateMediaItem call site never set Language
(explicit NULL over the column default), the update path did; create
now carries it.

Title-derived series fallback (§2.7): 'Baptism of Fire: The Witcher,
Book 3' 2-level folders split conservatively (only when the post-colon
tail matches ', Book N'), subtitle parsed for series+number, blanks-only
precedence, matching-name number fill, zero display mutation. Works
with no sidecar and no network.

Ingest fixes: subtitle/explicit land in their columns (audio tag
subtitle stops joining into title); full authors[] array (was [0]-
only); sidecar descriptions sanitized via bluemonday UGC policy
(vendored).

metadata_overrides: verified scan-update path already applies
ApplyMetadataOverrides; subtitle/explicit/authors covered by the Phase 1
override adaptation.

Tests: new series_parsing_test.go (string-array sidecar e2e, Drizzt
alternate_info, lossy raw preservation, playlist classification,
title-derived fallback incl. no-mutation + blanks-only, genre lexicon,
language map); audio-tag subtitle pin updated to column behavior;
calibre/ABS 2.5-series_index pins widened per float change (changelog'd
in phase 1).

Deferred to 2b: auto-created playlist collections (§2.4) — settings
toggle, collection upsert, ownership.

John O'Keefe 646477afad feat(schema): subtitle/explicit columns, authors+publishers arrays, float series numbers
Phase 1 of the series/collections/metadata overhaul
(~/.opencode/plan/series-collections-metadata-overhaul.md).

Schema (in place, idempotent):
- media_items.series_number INTEGER -> DOUBLE PRECISION: real-world
  ordinals are decimals (0.5, 1.5 novellas); INTEGER silently truncated
  them (calibre 2.5 pinned as 2 in tests).
- + subtitle TEXT, explicit BOOLEAN (sidecar ingest; ABS explicit /
  Audible isAdult).
- + authors/authors_search/publishers/publishers_search TEXT[] NOT NULL
  (narrators A2a precedent). Arrays are write truth; author/publisher
  varchars become trigger-regenerated display strings
  (sync_author_publisher_display) so every varchar consumer (trgm
  search, facets, API, OPDS/Kobo) keeps working unchanged.
- Row-level NULL normalization for the new arrays in
  set_library_type_name (A2 lesson: Go nil -> explicit NULL -> 23502).
- Backfills ARRAY[author]/ARRAY[publisher] — deliberately no
  comma-splitting ('Tolkien, J.R.R.' would corrupt; scanner kept only
  authors[0] historically).
- collection_items.position INTEGER + (collection_id, position) index
  for playlist ordering.

Go: sqlc regen; MediaMetadata/handler params gain Subtitle/Explicit/
Authors/Publishers (legacy singles still accepted, arrays win);
SeriesNumber int32 -> float64 end to end; metadata_overrides adapted
with legacy override keys ('author'/'publisher') preserved so existing
user overrides survive; bulk author edit writes the array.

Pins widened (docs/contract_pins.md): raw sqlc row key set + the six
new columns; changelog entry added.

Verified: unit suite green; integration sweep (bulk/smart collections/
scanner/stats/sync/queue/calibre/pins/audiobooks) green against the
shared dev DB after in-place migration. Pre-existing unrelated red:
TestOwnershipAndAdminTestSuite/TestAdminCreateUser timezone inheritance
fails identically at the pre-change commit (live shared state).

John O'Keefe 6216bd9bcf feat(audiobooks): multi-file books (folder-of-tracks + zip) + exhaustive metadata ingestion
Multi-file book ingest: a directory of ≥2 audio files (recursively —
disc-part folders like CD1/Disc 2 merge upward, siblings never merge)
ingests as ONE book whose file_path is the book-root directory; a zip
of audio tracks is its own book (file_path = the archive). Both write
the documented chapters abstraction {index,title,start,end} into
audio_metadata and add additive keys: layout ("folder"|"zip") and a
tracks[] manifest (per-track path, global-seconds start/end, duration,
size). Pre-grouping one-track strays under a book root are absorbed on
rescan (annotations cascade). Rescans take a stat-only fast path
(track count + total size + known durations unchanged → no re-probe —
a 1189-track book must not re-ffprobe every auto-scan); a zero-duration
book counts as changed so a ffprobe-equipped rescan fills durations in.
Folder-book roots count as present in the archive lifecycle pass, and
per-item rescan (RescanMediaItem) routes multi-file books through a
book-level refresh — the generic updater would read the root/zip as if
it were the book file and clobber format_group with "unknown".

Serving: GET /api/media-items/:id/chapters gains additive layout +
tracks keys (urls → the new endpoint). New GET
/api/media-items/:id/audio/:trackIndex streams one track — folder
tracks served from the real file (full Range via ServeContent), zip
tracks via a reopen-and-skip ReadSeeker over the entry (deflate has no
random access; acceptable at audio bitrates; stored entries stay
section readers). Both endpoints gate on library visibility (403 on
hidden libraries — family-lens rule). ServeFile and OPDS DownloadBook
refuse directory paths (folder books have no single-file download).

Web player (next commit) consumes the manifest; progress/bookmarks/
deep-links keep their global-seconds coordinates, so the server-side
progress model is untouched. sync learns FormatGroupAudiobook
(percentage passthrough in ConvertProgress); detectFormatType stops
reporting "unknown" for audio.

Metadata ingestion (Batch B) — read everything available, degrade
gracefully, documented precedence sidecars → folder structure →
embedded tags → filename: ffprobe tags are now a case-insensitive
lookup map (freeform keys pass through verbatim); composer fills
narrators (Audible's own convention, kept as ONE string — no reliable
multi-narrator delimiter); grouping + Audible freeform atoms
(SERIES/SERIES-PART/SUBTITLE/ASIN/ABRIDGED) fill series/index/
subtitle-join/ASIN/abridged (explicit sidecar abridged-false is
guarded); date/genre fall back to tags; album/album_artist/artist
fill title/author. Genre persists at create for all formats.
Embedded cover art (mp3 APIC, m4b covr, flac picture) extracts via one
optional ffmpeg call as a "<book>.cover.jpg" sibling — sidecar covers
win. CUE sheets (FILE-matched, INDEX 01 at 75fps) are the lowest-
priority chapter source under sidecars and embedded m4b chapters. A
lone m3u/m3u8 in a book root imposes playlist ordering + #EXTINF
names; (disc, track) tags reorder tracks when coverage is complete.
extractMetadata's default branch no longer pre-fills the filename as
title (tags must outrank it) — final filename fallbacks now exist on
BOTH the create and rescan paths (TestRescanKeepsFilenameTitle pins
that rescans cannot blank a title); tagless zip books take the zip's
own name, not their parent folder's.

Accepted containers widen to .m4b .m4a .mp3 .flac .zip .opus .ogg .oga
.aac .wav with real media types registered (audio/ogg per RFC 7845 for
Opus-in-Ogg) — all browser-playable; .wma deliberately excluded.

Tests: unit tests for CUE parsing, playlist hints, tag fallbacks
(synthetic ffprobe reports — ffmpeg cannot write Audible freeform
atoms), ordinal parsing, tag ordering, natural sort, grouping rules;
integration suite (11 tests) over the live dev DB: folder/zip ingest +
idempotency, stray absorption, chapters manifest, per-track streaming
with Range, hidden-library 403s, embedded covers + sidecar-wins, CUE
chapters, embedded m4b chapters, playlist ordering, tag fallbacks, all
five new containers with content-type assertions, rescan title pin.
Fixture media is real committed-format binary content living untracked
under internal/services/testdata/ (gitignored by policy; recipes in
docs/contributing/development.md → Media fixtures). Test image now
ships ffmpeg to match the runtime's audio toolchain.
