The inbound-document store encrypts the raw upload (`inbound_documents.content_encrypted`) because it is sensitive clinical data, but the per-fact staging columns persisted the same class of data in the clear: `extracted_facts.data_json` held the transcribed clinical values (diagnosis text, lab values, medication names, stated codes) and `provenance_json` held the verbatim source span (up to 2000 chars copied straight out of the report). The at-rest guarantee was defeated for staged facts, which persist through PENDING and are retained after the decision. Convert both columns to the AES-256-GCM `*_encrypted` BYTEA convention shared with the note columns, going through the same Bytes codec. The upload and fact-edit paths encrypt on write; the confirm path decrypts at commit time to write into the normal structured stores, so the review-then-confirm flow is unchanged. Reads are fail-closed (a bad key id throws). Register both columns in the encrypted-columns registry and the key-rotation script so a dropped legacy key cannot strand them (the guard test enforces both). Migration 0220 swaps the plaintext JSONB columns for the encrypted BYTEA columns; pre-confirm staged rows are ephemeral and cannot be re-encrypted in SQL, so any left by a pre-release build are dropped rather than retained as plaintext (their parent document keeps its encrypted original).
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).
