Marc-André Bombeck 3d55289ba3 feat(workouts): attach a heart-rate series to a workout already stored
A batch entry matching a stored workout stays first-write-wins for the
workout row. What it can do now is hand over a heart-rate series the
stored workout does not have yet: the series is attached, the row itself
is not written at all, and the entry reports back as `enriched`. A
workout that already carries a series is a no-op, so a client can walk
its whole history as often as it likes.

- The pre-flight probe now answers both questions at once, whether the
  row exists and whether it already has a series, and carries the id so
  the attach addresses the stored workout without a second round trip.
- The attach rides the same child write as a fresh workout's series.
  RETURNING names the rows that landed, so a workout that gained a
  series between probe and write reports as the duplicate it is instead
  of claiming an attach that never happened.
- A `samples` array that fails validation is refused per entry with
  `reason: "invalid_samples"` rather than failing the batch. One
  unusable session out of a hundred must not stall a history sweep the
  client cannot repair by retrying; every other validation failure keeps
  failing the batch.
- The wide event and the audit row tally enrichments. Counts only, the
  series never reaches either.
- `enriched` is the one contract movement: additive on the per-entry
  status, request shape unchanged. OpenAPI regenerated.

Integration coverage against a real Postgres pins the attach, the
repeat as a no-op, the refusal of a bad series alongside entries that
land, a mixed batch reporting each status, and the stored workout row
compared whole before and after, `updated_at` included.

HealthLog API Spec

openapi.yaml is the canonical OpenAPI 3.1 description for the HealthLog Next.js API. It is the source of truth for the native iOS client's DTO codegen.

The MCP server is documented separately — it is a distinct contract over JSON-RPC, not part of the REST OpenAPI spec:

Validate

npx @redocly/cli lint docs/api/openapi.yaml

The spec is expected to be lint-clean (errors = 0). Some warnings are intentional:

  • no-server-example.com — http://localhost:3000 is the dev server.
  • operation-2xx-response / operation-4xx-response — webhook + redirect endpoints intentionally omit one or the other.
  • no-unused-components — ReminderPhase is exposed for client codegen even though no path response references it directly.

Layout

  • info — title, version (mirrored from package.json), description.
  • servers — production https://healthlog.bombeck.io plus http://localhost:3000 for local development.
  • tags — domain groupings (Auth, Measurements, Medications, Mood, Dashboard, Insights, Achievements, DoctorReport, Integrations, User, Tokens, Notifications, Onboarding, Health, Settings, Analytics, Export, AuditLog, Monitoring, Webhooks, Ingest, Admin).
  • securitySchemes:
    • bearerAuth — long-lived hlk_* API tokens issued via POST /api/tokens. Required on /api/ingest/medication.
    • sessionCookie — HttpOnly healthlog_session cookie set by the password and passkey login flows. Used by the web app and any iOS client running inside a web view.
  • components.schemas — DTOs for all routes plus the underlying Prisma models (e.g. Measurement, Medication, MedicationIntakeEvent, MoodEntry, User, DashboardLayout, ApiEnvelope, ApiError).
  • paths — all routes from src/app/api/**/route.ts, including the /api/admin/* family which is tagged Admin and marked internal.

Conventions

  • Successful responses use the envelope { data, error: null }.
  • Error responses use the envelope { data: null, error: '<message>' }.
  • Pagination uses limit + offset query parameters and a meta: { total, limit, offset } block on the response.
  • All timestamps are ISO 8601 / RFC 3339 (format: date-time) in UTC.
  • IDs are CUIDs (opaque strings).

Updating the spec

When adding or changing routes:

  1. Update the relevant route handler under src/app/api/**/route.ts.
  2. Mirror the change in openapi.yaml. Keep operationId camelCase and stable — the iOS codegen keys off it.
  3. Run npx @redocly/cli lint docs/api/openapi.yaml and resolve all errors. Warnings are tolerated when documented above.
  4. Bump info.version if the change is breaking for clients.
