## Description

<!-- SECTION:DESCRIPTION:BEGIN -->

_GitHub: created 2026-04-05 · updated 2026-04-09 · closed 2026-04-08 · not planned_

|
|
## Summary
|
|
|
|
Artist data exists in three different forms with no clear canonical source:
|
|
1. `Record` embeds `:artists` (embedded schema in record)
|
|
2. `ArtistRecord` — separate lookup table/view
|
|
3. `ArtistInfo` — external metadata store
|
|
|
|
## Why This Matters
|
|
|
|
- Unclear which representation is authoritative for a given use case
|
|
- Updates to one representation don't automatically propagate to others
|
|
- New developers must understand all three to work with artist data
|
|
|
|
## Affected Files
|
|
|
|
- `lib/music_library/records/record.ex` (embedded `:artists`)
|
|
- `lib/music_library/records/artist_records.ex`
|
|
- `lib/music_library/artists/artist_info.ex`
|
|
|
|
## Suggested Fix
|
|
|
|
Document the purpose and canonical use case for each representation. Consider whether `ArtistRecord` (DB view) can be simplified or whether the embedded artists on Record should be the single source for record-artist relationships.

|
## Acceptance Criteria

|
|
- Clear documentation of each representation's purpose
|
|
- Reduced confusion about which to use in new features
