Room climate from a home automation system gets three types of its own: INDOOR_CO2 (ppm), INDOOR_TEMPERATURE (celsius, shown in Fahrenheit for imperial readers) and INDOOR_HUMIDITY (percent). They arrive through the existing ingest token (measurements:write, source EXTERNAL), sit in the environment cluster beside daylight, and the daily rollup carries their mean, low and high like any spot reading. They never mix with the body temperatures or with the outdoor environment channels. The Home Assistant page documents the three types, a rest_command that sends a room as one request, a single-room automation, and an importable blueprint (docs/integrations/blueprints) that skips sensors reporting unknown or non-numeric states, converts Fahrenheit, and stamps readings to the minute so a retried push is refused rather than written twice.
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).
