Every raw-SQL clock read against a timestamp column without a zone now writes NOW() AT TIME ZONE 'UTC', so passkey and login challenges, rate limits, provider pauses, coach usage stamps, tombstone and measurement windows no longer pass through the session time zone even where the per-connection pin cannot apply. The regression-window bounds stay naive UTC timestamps instead of being turned into timestamptz. A structural guard keeps bare NOW() / CURRENT_TIMESTAMP out of raw SQL outside a short list of timestamptz targets. The integration test sets the database default to Europe/Berlin and drives challenge claims, session expiry, the native sign-in handoff freshness check and the rate-limit window through the app's client, plus the challenge claim through an unpinned client. Self-hosting docs describe the pin for an existing or shared Postgres.
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).
