upsertArtistSimilar keeps the existing matched path (top-K rows into
artist_similarity) and adds a parallel unmatched-persist loop with the
same top-K cap. Empty-name rows are skipped — we can't render a
suggestion card without a name. Logs unmatched-side errors at WARN
without aborting the tick (mirrors the matched-path policy).
Integration tests previously TRUNCATEd the users table at setup,
which wiped the operator's admin login every time the suite ran
against a Postgres instance shared with their dev environment.
This commit:
- Adds internal/dbtest/reset.go exposing ResetDB(t, pool) and
TestUserPrefix. ResetDB truncates every data table EXCEPT users,
then deletes only users whose username starts with TestUserPrefix.
- Migrates 9 test files (subsonic/scrobble, subsonic/star,
recommendation/candidates, scrobble/queue, similarity/worker,
playevents/writer, playsessions/service, api/auth, api/me) to
call ResetDB instead of issuing TRUNCATE-with-users.
- Renames hardcoded test usernames to use TestUserPrefix so ResetDB
cleans them between runs. seedUser in api/auth_test now prefixes
internally; existing call sites pass bare names.
- Leaves auth/bootstrap_test.go alone — it legitimately tests
first-time admin bootstrap and must wipe users.
Verified locally: full integration suite with -p 1 runs cleanly
under the existing MINSTREL_TEST_DATABASE_URL setup, and the admin
row in the shared dev DB survives the run.

Replace stub with full tickOnce: drains played tracks/artists via
ListPlayedTracksNeedingSimilarity / ListPlayedArtistsNeedingSimilarity,
calls LB SimilarRecordings/SimilarArtists, filters to local library via
bulk MBID lookup, enforces top-K=20 by score, and upserts similarity
rows. 429 aborts the entire tick; other errors log-and-skip. Ten
integration tests covering no-op, library filtering, top-K cap, 7-day
freshness cap, stale refresh, 429 abort, transient skip, and artist
pass.
