Marc-André Bombeck f4dec8c28f feat(medications): fractional dosing via decimal units per dose (#316)
A dose can now consume a fraction of a unit — a half, third or quarter
tablet for a split pill. The wizard offers a curated fraction set beside
the whole numbers (the most error-resistant input); units-per-dose and the
per-container counts widen from Int to Decimal, so a 30-tablet pack dosed
at a half reads 29.5 after one dose and the days-left projection follows.
The consumption ledger stamps and refunds the exact fraction, and existing
whole-number doses are untouched. OpenAPI regenerated — the three unit
fields move from integer to number — and the units-per-dose hint is
updated across the six locales.

Also anchors a first-use date relative to now in an inventory route test
that had aged past its 30-day in-use window.

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).
