Navidrome's Subsonic API does not return +MBIDs via `getArtists`/`getArtist`. Resolution: **add an `mbid` column to +`artist_settings`** and resolve it lazily during sync by querying MusicBrainz +artist search (`/ws/2/artist/?query=artist:&fmt=json`). Cache the MBID on +the artist row. This avoids manual config and keeps the schema the single source +of truth. (Alternative considered: resolve by name on every sync without +storing — rejected because it doubles rate-limited MB calls and is flaky on +name collisions.) + +## Development Approach +- **Testing approach**: TDD — write tests before implementation for each task. +- Complete each task fully (code + tests passing) before the next. +- Every task MUST include new/updated tests (success + error/edge cases). +- All tests must pass before starting the next task. +- Run `go test ./...` and `go vet ./...` after each task. +- Maintain backward compatibility of existing DB schema (additive migration only). + +## Testing Strategy +- **Unit tests** for every new function/method (success + error paths). +- **Integration-style tests** for sync/resolver using a `:memory:` DB and a + stubbed MusicBrainz HTTP client (the existing `client_test.go` already shows + the httptest pattern — reuse it). +- **Web UI**: table-driven tests for handlers (status codes, auth rejection, + ignore action effects on DB) using `httptest.NewServer` + in-memory DB.
