8e953e8bc4 library: opt-in gap-fill — write confirmed missing metadata into the pack (R4a) (#724)
* library: opt-in gap-fill — write confirmed missing metadata into the pack (R4a)

The write-back contract agreed with the spec chair (alignment doc §7),
made executable, now that feedpak-spec 1.14.0 (mbid/isrc) is merged:
opt-in + user-initiated, adds ABSENT keys only, spec'd-keys allowlist,
values only from a CONFIRMED identity, atomic write + .bak. Single-song
only — batch write-back stays an open question with the chair.

- songmeta.gap_fill_sloppak: append-only manifest writer. Every added
  key is absent by definition, so the new lines are APPENDED — the
  author's existing bytes (key order, comments, formatting) survive
  verbatim, unlike the metadata editor's full re-serialize. Directory
  form gets a one-time manifest.yaml.bak + temp + atomic replace; zip
  form reuses the editor's backup/temp/replace rewriter. Raises on any
  already-present key: the never-clobber rule lives in the writer, not
  just the callers.
- GET /api/song/{fn}/gap-fill: read-only preview — which of
  album/year/genres/mbid/isrc are missing from the file (absent or
  empty; year 0 = empty), with the values the enrichment match
  supplies. Only a CONFIRMED identity is eligible (matched or a user
  pin); review-tier rows are refused until a human confirms —
  wrong-match > fast, same as everywhere else in the enrichment layer.
- POST /api/song/{fn}/gap-fill {keys}: writes the user-confirmed
  subset. Proposals are RECOMPUTED under _song_io_lock, so a key that
  gained an author value between preview and confirm is skipped, never
  replaced. mbid/isrc written in canonical form only (validated).
  DB stays scanner-consistent (album/year/genre columns + mtime/size
  re-stat, cache invalidation + scan kick — the metadata editor's
  contract). Demo mode blocks the write.
- Details drawer (Identity section): "Write missing info to file…" →
  per-key checkbox confirm ("Only adds what's missing — nothing already
  in the file is changed. A backup (.bak) is kept.") → written
  confirmation; not-eligible states explain themselves. v3 only; no
  new tailwind classes.
- Rides along: _manifest_exact_ids now strips ISRC display separators
  (spec 1.14.0's strip rule) — a hand-authored "AU-AP0-90-00045" hits
  the exact-match tier instead of silently falling back to text.

Tests: tests/test_gap_fill.py (10) — preview eligibility incl.
review-refusal + empty-as-gap, author-bytes-preserved-verbatim on dir
AND zip (with .bak content pinned), skip-not-replace on the mixed
request, the writer's ValueError guard, key validation, demo block,
DB sync; +1 hyphenated-ISRC test in test_mb_enrichment.py. 46 targeted
green; full-suite failure set A/B-identical to the main base (39
env/pre-existing).

* gap-fill: align preview with append-only writer (no cleared-value 500)

The R4a preview offered present-but-empty manifest values (album: '',
genres: [], year: 0) as gaps, but the append-only writer's never-clobber
guard raises on ANY key already present — so a user-confirmed POST for
those keys turned into a 500 "write failed" instead of filling the gap.
Appending can't fill an empty-but-present key anyway (it would duplicate
the YAML key).

Fix: _gap_fill_manifest_absent now treats only genuinely-MISSING keys as
gaps; a present-but-empty value is left to the metadata editor (which
re-serializes and can replace in place). This closes the preview→POST
mismatch — the preview never offers what the writer would refuse.

Tests: test_preview_treats_empty_values_as_gaps replaced by
test_preview_excludes_present_but_empty_keys (present-but-empty not
offered; genuinely-absent still offered) + test_write_present_but_empty_
key_is_refused_not_500 (POST → clean 409, file untouched, no .bak; a
genuinely-absent key alongside still writes). Closes the write-path blind
spot in the original empty-value test.
