Marc-André Bombeck c5d2053e5a fix(hrv): file Fitbit and Google Health RMSSD as HRV_RMSSD
Fitbit's `dailyRmssd` and Google Health's daily HRV average are both
RMSSD, but the mappers wrote them into HEART_RATE_VARIABILITY, the SDNN
series. The `hrv` ladder ranks both above Apple Health, so an account
with an Apple Watch and a Fitbit had a series that switched estimator
from day to day. The mappers now write HRV_RMSSD, and the `hrvRmssd`
ladder carries both sources where they sat on the SDNN one.

Migration 0420 moves the rows already written (tombstones included,
with a sync-version bump so the change reaches the phone), drops their
SDNN rollup buckets and the RMSSD buckets of every account whose rows
moved, so the boot-time rollup discovery folds those accounts again,
and deletes the SDNN personal records those rows had set. One DO
block, so the move and its cleanup land together.

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_case columns via @map(...), encrypted columns mostly suffixed *Encrypted (search the file; there are 24 encrypted column references). The generator client block emits to ../src/generated/prisma (imported as @/generated/prisma).
  • migrations/ — numbered, forward-only SQL migrations (0001_… upward). migration_lock.toml pins the provider to postgresql.

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: *Encrypted columns are written through @/lib/crypto (AES-256-GCM, versioned key ids); never store plaintext in an encrypted column. Key rotation is scripts/rotate-encryption-key.ts + docs/ops/encryption-key-rotation.md.
  • The generated client under src/generated/prisma is build output — do not edit it.
  • Schema-touching changes that affect the API surface must regenerate docs/api/openapi.yaml (see ../CLAUDE.md).
