Marc-André Bombeck 6a173a89dd Enforce one active consent receipt per kind atomically
Two concurrent web-grant heals could each pass the read-then-create gap
and insert a duplicate active ai_full receipt; the revoke path then had
to chase one row at a time. Wrap the web-grant mint in a Serializable
transaction with an in-transaction re-check, and add migration 0159 — a
partial unique index over (user_id, kind) WHERE revoked_at IS NULL — as
the structural backstop. createReceipt now supersedes any active row of
the same kind before appending, and revokeLatest flips revoked_at via a
single atomic updateMany, so the append-only audit chain is preserved
while at most one active row ever exists.

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).
