| ReadFile Go method on FrontendUtil for cover art bytes | Native file dialog returns path; frontend needs bytes for blob preview + save payload |
| asInt/asBytes helpers for Wails JSON deserialization | Wails sends JS numbers as float64 and []byte as base64; direct type assertions silently fail |
| Cover art DB sync with content-hash dedup + thumbnail generation | Saves to covers cache dir, upserts cover_art row, updates release_groups.cover_art_id |
| suppressEvents flag for batch event coalescing | Prevents N TrackMetadataChanged events during batch; single emission after completion |
| Per-track pipeline lock (not batch-wide) | Avoids blocking scan for entire batch duration; each track acquires/releases independently |
| BatchResult struct return (not error) | Partial success always communicated; Wails serializes as JSON for frontend |
