Marc-André Bombeck 032ea5b1a0 Register the schema names the contract was discarding
Zod 4's `.meta()` clones the schema and registers the clone, so a bare
`someSchema.meta({ id })` statement registers nothing at all. Thirty-nine of
those across eleven route modules published neither the name nor the
description written for it: the schema inlined anonymously at every use site,
and a client generated from the contract got a duplicated nameless type where
one named model belongs. That last part is the cost that matters, because the
native client is the reason the contract is published.

Bind each annotated clone to a const and point the route table at that const.
Twenty-nine ids now emit under `components.schemas`, referenced from their
thirty use sites. Seven stay absent by design: they annotate
`requestParams.query` objects, which the emitter expands into inline
`parameters` rather than a component. `MoodTagLayout` stays absent too, for
the reason `Medication` and `CoachPrefs` already carry a forced registration
in the components block: its only consumer is an `.extend()`, and extending
builds a new object rather than referencing the base.

Two annotations in the illness module named ids that no route ever referenced,
`GetIllnessDayLogQuery` and `ListIllnessDayLogsQuery` — the day-log path
publishes the merged `GetIllnessDayLogsQuery` instead. They were dead twice
over, so they go rather than get wired to nothing.

`docs/api/openapi.yaml` grows the twenty-nine components and their refs. The
only other movement in it is thirty descriptions appearing where the text had
never reached the document. No request or response shape changes.

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.
