Marc-André Bombeck 4cb8118802 Let a person name their own medication categories
A medication can be filed under a category the person named, next to the
built-in ones (#1041). The labels live in medication_category_labels,
encrypted at rest, capped at 20 per account; a medication filed under one
carries its custom:<uuid> key in the category column.

- GET/POST /api/medications/categories (POST idempotent, 30/min per actor,
  admitted at MANAGE like the cycle symptom vocabulary) and owner-only
  PATCH/DELETE /api/medications/categories/{key}. DELETE moves every
  medication filed under the category to OTHER in the same transaction
  and answers movedCount.
- category is widened to a built-in value or custom:<uuid> on the wire,
  the create and update bodies refuse a key that is not the caller's
  (422 medications.category.unknown), and list, detail, the insights
  medication tiles and the MCP medications resource carry categoryLabel.
  A key with no owned label reads as OTHER and is counted on the event.
- The wizard's class step lists the person's categories under the
  built-in rows with an inline add row; the list page gains a category
  filter (session only) and a manage sheet for rename, hide and delete.
- Backup carries customMedicationCategories (decrypted labels) and the
  restore writes them before the medications; wipe plan, encrypted
  column registry, rotation script, sharing guards and OpenAPI follow.

prisma/

The database layer. HealthLog runs PostgreSQL 16 via Prisma 7. This directory holds the single schema file and the forward-only migration history; the generated client is emitted elsewhere.

Contents

  • schema.prisma — 61 models, one file. cuid() primary keys, snake_case columns via @map(...), encrypted columns mostly suffixed *Encrypted (search the file; there are 24 encrypted column references). The generator client block emits to ../src/generated/prisma (imported as @/generated/prisma).
  • migrations/ — numbered, forward-only SQL migrations (0001_… upward). migration_lock.toml pins the provider to postgresql.

Migration workflow

# author a migration from a schema edit
pnpm dlx prisma migrate dev --name <short_snake_case_name>

# regenerate the client after any schema change
pnpm dlx prisma generate

Number a new migration with the next free prefix. The production entrypoint runs prisma migrate deploy on boot, so every migration must apply cleanly forward — there is no down-migration path. Always include the migration file in the same change as the schema edit.

Conventions

  • Encryption is fail-closed: *Encrypted columns are written through @/lib/crypto (AES-256-GCM, versioned key ids); never store plaintext in an encrypted column. Key rotation is scripts/rotate-encryption-key.ts + docs/ops/encryption-key-rotation.md.
  • The generated client under src/generated/prisma is build output — do not edit it.
  • Schema-touching changes that affect the API surface must regenerate docs/api/openapi.yaml (see ../CLAUDE.md).
