The recommendation scoring knobs move out of YAML (radio profile) and
out of the systemMixWeights hard-code (daily_mix profile) into
DB-backed settings with live effect (#1250) — the defaults-discovery
lab per decision #1247: the operator turns knobs to find good values,
which then get baked back into shipped defaults; end users and other
operators should never need the card.
- Migration 0040: recommendation_weight_profiles (radio / daily_mix,
8 weight columns), taste_tuning singleton (engagement half-life +
completion-curve points), recommendation_tuning_audit (one row per
change with a {field, old, new} diff — the trend view's markers,
#1251).
- internal/recsettings: boot reconcile seeds shipped defaults without
clobbering tuned rows (coverart SettingsService pattern), validates
patches (bounds, curve ordering), writes audit rows, and pushes
daily_mix weights + taste config into package playlists. No-op
patches write no audit row.
- playlists gains SetSystemMixWeights / SetTasteConfig swap points
under a RWMutex — no signature threading through the producers; the
scheduler's taste rebuild reads the pushed config.
- Radio reads its weight profile from the service per request; the 8
weight fields leave config.RecommendationConfig (YAML keeps only
RecentlyPlayedHours / RadioSize / RadioSizeMax).
- Admin API: GET/PATCH/reset under /api/admin/recommendation-tuning,
echoing current + shipped values.
- Web: new admin Tuning tab — two weight profiles side by side, taste
card, per-scope save (changed fields only) + reset, deviation dots
against shipped defaults.

A redo: the prior commit truncated cover_art_sources_meta, but
SettingsService.reconcile() only READS that singleton (seeded once by
migration 0018) and never recreates it → ~45 coverart/api tests hard-
failed "get current sources version: no rows". Correct reset: keep
cover_art_provider_settings in the truncate set (boot idempotently
re-UpsertProviderSettings), drop cover_art_sources_meta from it, and
instead `UPDATE cover_art_sources_meta SET current_version = 1` so the
row survives while cross-test version accumulation is cleared.
B residual (exposed once the play_events FK fix let these run):
- seedQuarantine used reason 'test-hide', invalid for the
lidarr_quarantine_reason enum (bad_rip/wrong_file/wrong_tags/
duplicate/other) → use 'other'.
- TestBuildSystemPlaylists_SufficientActivity predated #411/#352: the
variant switch errored on the 5 new seedless mixes and capped
track_count at 25. Accept deep_cuts/rediscover/new_for_you/
on_this_day/first_listens as seedless; raise the cap to 100.
Test/test-harness only.

Latent failures exposed now that integration tests run in CI (#339).
All test/test-harness only — no production code changes.
A (dbtest.ResetDB): also truncate cover_art_provider_settings +
cover_art_sources_meta. The monotonic source-version counter (seeded 1
by 0018) accumulated across internal/coverart tests → CurrentVersion=4
want 1, key-only-bump assertions, enricher source skips. SettingsService
re-seeds both at boot, so a truncated start is the correct fresh state.
B (playlists system_test.seedPlayEvent): inserted play_events with a
random session_id → play_events_session_id_fkey violation (7 tests).
Create the parent play_sessions row in the same statement (CTE).
C (similarity worker_integration_test.newTestWorker): built the client
with only BaseURL. Post-4fca0e6 similarity hits the Labs API via
LabsBaseURL, so an unset LabsBaseURL fell through to the real labs.api
and the stub never ran → 0 similarity rows. Set LabsBaseURL to the stub.
F (library scanner_test): NOT a flake — deterministic. Synthetic
ID3-only MP3s have no decodable duration; the scanner intentionally
won't skip duration_ms=0 rows (retries duration backfill), so every
re-scan reported Updated not Skipped. Seed duration_ms>0 before the
second scan so the mtime-based incremental-skip path under test is
actually exercised. Production scanner behavior unchanged.

New package internal/sync. LogChange writes a library_changes row inside
the supplied tx. Encode helpers produce stable composite ids for like_*
and playlist_track entries. Subsequent commits wire LogChange into the
scanner / likes / playlists services.
Also: dbtest.dataTables now includes library_changes so test isolation
holds across runs.

Create / Get / List / Update / Delete with the visibility model from
the spec: private by default, owner-only mutations, public read for
non-owners. Update uses sqlc's CASE-WHEN-flag pattern for PATCH-style
partial updates without writing N variants.
Delete cleans up the cached cover file from disk best-effort. Track
operations (Append/Remove/Reorder) and the collage generator land
in subsequent tasks.
Also adds playlists + playlist_tracks to dbtest.ResetDB's truncate
list so integration tests in this package start from a clean state.

- dbtest.ResetDB.dataTables now truncates lidarr_quarantine + lidarr_quarantine_actions
alongside the other M2-M4 data tables. Without this, M5b service tests would
inherit residual state across runs.
- DeleteTrackFile godoc spells out the post-file/pre-DB failure window
reconciles via the next library scan; the function is retry-safe by design,
not atomic.
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.
