Discovery seeded only from followed artists. Now it also seeds from artists
you own albums by (LibraryItem.artistMbid, captured since the MBID own-state
work) but don't follow — so your library shapes suggestions, not just your
follows.
- New DiscoverySeed throttle table (migration add_discovery_seed) mirroring
WatchedArtist.lastDiscoveredAt, so each library-derived seed is swept once
per interval (WatchedArtist seeds keep their own throttle).
- _seed_artists merges both seed sources least-recently-swept first, capped at
chunk_size; run_discovery stamps the right throttle per seed and evicts
contributions from seeds that are neither followed nor owned.
- Artists you already have (followed OR owned) are excluded from the suggestion
candidates — discovery surfaces only genuinely new artists.
- discover.seedFromLibrary config (default true) + a Discovery settings toggle.
NOTE: existing LibraryItem rows have null artistMbid (populated on new
import/scan), so a re-scan is needed before old albums seed discovery.

Each suggestion now carries the followed artists (seeds) that surfaced it,
from DiscoverySeedContribution joined to the current watched roster (an
unfollowed seed drops out), highest-scoring seed first. /discover renders
"Similar to Arctic Monkeys, Coldplay +2" under each artist and album row —
both kinds key off the candidate's artistMbid, so an album inherits its
artist's seeds. web 187 tests.

The library scan silently skipped album folders with no MusicBrainz match
(or an unreadable file). Persist them so they're visible and fixable.
- New UnmatchedAlbum model (migration add_unmatched_album), keyed by path.
- scan_chunk records a skipped album as unmatched (reason "no MusicBrainz
match" or "unreadable: <err>"), clears the row when an album later
resolves, and prunes stale rows (a prior scan's, or a removed folder)
when a scan completes.
- GET /api/library/unmatched lists them; DELETE ?id= dismisses one.
- /library shows a "Couldn't match" section (path + reason + Dismiss).
Worker + web tests added.

Reopening an artist (discography), an album (tracklist), or repeating a lookup
re-hit MusicBrainz every time with no cache and no throttle. Adds a generic
Postgres-backed read-through cache keyed on the LOGICAL operation (not the
request URL) so the worker and web app share entries.
- New ApiCache(key, json, fetchedAt) model + migration (generic name so the
Last.fm browse cache can ride the same table).
- lib/apicache.ts cached(): read-through, TTL from fetchedAt (tunable, no
migration), serve-stale-on-outage, never caches null.
- Wrap the high-level MB fns with logical keys + TTLs: discography &
tracklists & artist-name 30d, searchReleaseGroup 7d, searchArtists 1d.
Search keys normalized (trim+lowercase) to match the worker byte-for-byte.
- album-modal: a session-scoped Map<rgMbid,Track[]> so reopening is instant
with zero network (complements the DB cache).
- Test setup clears ApiCache between tests. web 147 tests, tsc + build clean.

Test suites were running DELETE FROM.../deleteMany() against whatever
DATABASE_URL pointed to, which was the live app database, wiping user
credentials and library. Add a guard in both the worker conftest and
web test setup that raises before any cleanup unless the target DB
name ends in '_test'. Default DATABASE_URL to lyra_test when unset in
the worker, and make `npm test` target lyra_test explicitly.
