Add first-class qualitative lab findings (positive / negative / borderline serology) alongside the existing numeric path. A LabResult is now EITHER a numeric reading (value + unit, optional reference bounds) OR a qualitative one (valueText, e.g. "negativ"), never both, never neither. - schema: make `value` nullable, add `value_text`; migration 0181 is additive (DROP NOT NULL + ADD COLUMN), every existing numeric row is untouched. - validation: numeric-XOR-qualitative refine on create + update; unit/bounds apply to the numeric path only; valueText capped at 120 chars. The single resource PUT rejects a cross-type edit. - serialise: carry valueText through both DTOs; a qualitative row reports the neutral `unknown` range verdict (no number to classify). - FHIR: a qualitative result emits valueCodeableConcept — SNOMED qualifier value for confidently-known terms (Negative 260385009, Positive 10828004, Not detected 260415000, Detected 260373001), text-only for borderline / grenzwertig and any unrecognised term. The raw text always rides .text. - UI: a numeric/qualitative toggle in the lab form; list, history, detail, chart, sparkline, and the doctor-report PDF all render qualitative readings as their text and never plot or divide on a null value. - i18n: new labs.form keys across all six locales. - openapi: response carries a nullable value + valueText; regenerated.
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).
