REFERRAL joins the document-kind enum (Überweisung — LOINC 57133-1 / ePA ANF). inbound_documents gains content_sha256 (plaintext hash for same-user duplicate detection; pre-existing rows stay NULL) and content_codec (base64v1 legacy string codec | binary2 binary codec, explicit column — never header-sniffed), plus a partial unique index that allows at most one LIVE row per (user_id, content_sha256) so a tombstoned document never blocks a re-upload. document_condition_links is the m:n join between a document and an illness/condition episode (a discharge letter legitimately touches two conditions); both sides cascade. app_settings carries the two admin-tunable limits (per-file cap, default 25 MiB; per-user quota, default 1 GiB) and users the nullable per-user quota override. Task: W1-T1.
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).
