Marc-André Bombeck ce41d5bf17 fix(fitbit): key sleep segments on their start instant and sweep re-score leftovers
Fitbit re-scores a night after the fact, and the per-segment externalId carried
a positional index plus the stage label. Both moved on a re-score: renumbered
segments minted fresh keys, the previous scoring's rows stayed live because
nothing swept them, and the night total counted both copies from then on.

Key the segment on the stable session anchor plus its own start instant
(`<logId>:sleep:<segment-start>`), and add the replace-by-window sweep every
other segment-writing provider already has. The two ship together with the
natural-key rescue that has been sitting in the Fitbit upsert unused: the sweep
tombstones the old-keyed rows first, so the rescue re-keys those very rows in
place instead of inserting a parallel copy or losing the insert to
`skipDuplicates` against the natural unique index.

A one-shot repair queue re-reads the bounded sleep history once per connection
so no user has to do anything; it stamps `sleepRepairedAt` (migration 0270) only
on a clean run, never touches the sync watermark, and reports the rows it
removed. Nights older than the 365-day backfill horizon keep their old keys and
whatever duplicates they already hold — they can no longer gain new ones.

Alongside: `fitbitGet` now honours a `Retry-After` inside a 120 s cap by waiting
once and retrying once, and fails fast above it so a long hold cannot starve the
rest of the poll cohort or outlive a job's expiration. The measurement upsert
skips a write whose payload is unchanged, which takes the hourly overlap off the
delta feed for every Fitbit resource.

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).
