On a completed sign-in (password, second-factor, or passkey) from a device or location not seen before, send one notification through the dispatcher cascade, honouring the user's per-channel preferences via a new SECURITY_ALERT event type. Dedupe on a one-way, per-user fingerprint: a SHA-256 over the userId, the coarse User-Agent family, and a country/ASN-level geo signal, stored in the new user_known_devices ledger (migration 0203). The first sighting of a fingerprint alerts and records; later sightings only bump last-seen and stay silent. The raw User-Agent and IP are never persisted — only the salted hash and a coarse label. Registration records its device silently so a fresh account does not alert on its own first session. The whole path is fire-and-forget and never blocks or fails a sign-in.
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_casecolumns via@map(...), encrypted columns mostly suffixed*Encrypted(search the file; there are 24 encrypted column references). Thegenerator clientblock emits to../src/generated/prisma(imported as@/generated/prisma).migrations/— numbered, forward-only SQL migrations (0001_…upward).migration_lock.tomlpins the provider topostgresql.
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:
*Encryptedcolumns are written through@/lib/crypto(AES-256-GCM, versioned key ids); never store plaintext in an encrypted column. Key rotation isscripts/rotate-encryption-key.ts+docs/ops/encryption-key-rotation.md. - The generated client under
src/generated/prismais build output — do not edit it. - Schema-touching changes that affect the API surface must regenerate
docs/api/openapi.yaml(see../CLAUDE.md).
