Marc-André Bombeck 7ddcee0445 Publish the health-score configuration route
/api/auth/me/health-score-config shipped in v1.35.0 with a settings page
in front of it and no entry in the contract at all — no path, no schemas,
nothing. A client had the surface and no way to generate against it. This
is publication only; the route does what it already did.

Both verbs are registered off what the route actually returns rather than
off a neighbour's shape. The asymmetry matters and is now written down: the
request speaks the positive selection, the pillars that should count, while
the response carries both sides resolved plus the recipe version. The column
stores the complement, which is storage and no client's business.

The response's updatedAt is documented as optional because it genuinely is
absent until a selection exists — an account that never chose has nothing to
guard a write against, and a decoder that required the field would break on
that read.

The PATCH 422 is written out rather than reusing the shared base-token
response, because this route has four of them and a client branching on
meta.errorCode needs all four: the breadth refusal with the sentence to show
the person, the validation failure, the unparseable base token, and the
non-JSON body. Naming only the token would have been a contract that omits
the refusal people actually hit.

The route test now drives the real route to produce each of those responses
and asserts the published contract names every code that comes back, so a
response the route can emit but the spec does not describe fails the suite.
That closes the base-token ledger: nine routes emit invalid_base_updated_at
and all nine now document it.

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.
