A record's cycle calendar subscription is a URL credential: one row per feed, only the HMAC of the raw hlf_ token stored, and at most one live feed per record through a partial unique index on user_id where revoked_at is null. Both foreign keys cascade, so deleting the record or the carrier who minted the feed ends it. The row is a credential everywhere else too. It stays out of the backup (a restore would bring back a revoked link), Delete All Data takes it on both sides, a credential remediation revokes the feeds on the record and the ones the account minted elsewhere, and a managed-profile handover claim revokes any feed a guardian minted. backupVerdict moves beside the plan into its own module so the plan stays the lists and their reasons.
prisma/
The database layer. HealthLog runs on PostgreSQL 18 (the compose default) or 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).
