The limit=200 fix only helped FRESH fetches. The metadata cache is persistent
(SQLite, 30-day TTL), so any album whose tracklist was cached at 50 BEFORE the
fix keeps returning 50 from cache in every window that loads it (line returned
the cached entry without revalidating) — which is why the Standard-view add-album
modal still showed 50 while a freshly-fetched album in the download window showed
the full list. Same album, different cache state.
Fix: get_album_tracks now marks freshly-fetched entries '_complete'. On a cache
hit, a legacy entry without that flag is revalidated against the album's known
trackCount (from collection metadata, unaffected by the bug) and re-fetched if
short. The '_complete' flag makes the heal one-time and avoids a re-fetch loop on
region-restricted albums where available tracks < trackCount.
Tests: stale-truncated -> refetch+heal; _complete -> trusted; legacy-complete and
unknown-trackCount -> trusted (no regression). Fresh fetch carries _complete.
iTunes get_album_tracks called _lookup(id, entity='song') with no limit. The iTunes Lookup API
returns only 50 related entities unless limit is passed (max 200), so albums over 50 tracks showed
only the first 50 in the download window. Pass limit=200 on the main lookup AND the fallback-
storefront request.
Proven against the live iTunes API on the reporter's exact album (Frieren OST, id 1739445636,
70 tracks): no limit -> 50 songs, limit=200 -> 70 songs. Spotify already paginates; Deezer uses
limit=500 — iTunes was the only truncating source. Regression test asserts limit=200 is requested.
