R-E H-5. Up to v0.4.1.1 the iOS app stored mood-entry prose as
`tags: ["note:<text>"]` because the server had no dedicated column.
The workaround contaminated the tags axis with prose the Coach
evidence shelf misread as taxonomic labels.
Schema (migration 0063, additive):
- mood_entries.note (TEXT, nullable)
Validation + routes:
- createMoodEntrySchema gains optional note (max 500 chars)
- updateMoodEntrySchema accepts note + null to clear
- POST /api/mood-entries persists note alongside tags
- PUT /api/mood-entries/[id] honours partial note updates
- POST /api/mood-entries/bulk carries note through the bulk path
Backfill script at scripts/backfill-mood-note-column.ts lifts the
legacy note:<text> tag entries into the new column. Idempotent
dry-run mode is the default; --confirm commits. Helper logic lives
in src/lib/mood/note-backfill.ts for tight unit coverage.
iOS contract: additive. Old iOS payloads (no note field) round-trip
unchanged. New iOS code paths can read or write note without
touching tags.
