Marc-André Bombeck df5dd1c160 docs: publish the Bearer arm on the two erasure routes
The published contract still told a client that a Bearer token can never
clear the step-up on account deletion or the record wipe, which is what
an app generates its client from. Describe the elevation arm on both:
which factors qualify, that a password proof does not, that the proof
rides the X-Step-Up header, and that it is spent only when the erasure
runs. The 403 a narrow-scope token gets was never published either;
it is named now, ahead of the second-factor question it precedes.

The mint endpoint lists the surfaces an elevation unlocks, so both
routes join that list.

Also note on the record wipe that API tokens are on its own delete list:
a client that wipes over Bearer signs itself out, which is worth knowing
before the retry rather than after it.

HealthLog API Spec

openapi.yaml is the OpenAPI 3.1 description for the HealthLog Next.js API and the source of truth for the native iOS client's DTO codegen. The file is generated: pnpm openapi:generate emits it from the Zod registry under src/lib/openapi/ (registry.ts plus the route modules in src/lib/openapi/routes/). Do not edit the YAML by hand; the next generation overwrites it, and CI (openapi:check) fails the build when the committed YAML drifts from the registry.

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

The spec is expected to be lint-clean (errors = 0). Warnings such as no-server-example.com for the localhost dev server are tolerated; re-run the lint to see what it produces against the current file before treating a warning as a regression.

Layout

  • info — title, description, and version mirrored automatically from package.json at generation time. Never bump it by hand.
  • servers — https://healthlog.example.com as the self-hosted placeholder plus http://localhost:3000 for local development.
  • tags — domain groupings; the current set lives at the top of the generated file (Auth, Measurements, Medications, Mood, Analytics, Insights, Consent, Dashboard, Notifications, Devices, Export, Sync, Cycle, MeasurementReminders, Labs, Illness, Documents, Records, Admin, Meta, Retired).
  • securitySchemes:
    • bearerAuth — hlk_* API tokens. A scope grants what it names and nothing adjacent, so where a token comes from decides what it reaches:

      • a completed password / passkey / refresh exchange mints the cookie-equivalent ["*"] token the native client carries;
      • a medication's own API-endpoint toggle mints medication:ingest plus medication:<id>:ingest, the pair /api/ingest/medication gates on;
      • POST /api/mcp/tokens mints health:read (optionally plus health:write), audience-bound to /mcp and refused on REST writes;
      • POST /api/tokens/measurements mints measurements:write, accepted by POST /api/measurements and POST /api/measurements/batch only, on the holder's own record only.

      POST /api/tokens is not among them — that generic mint was removed in v1.30.17. The path still lists (GET) and revokes (DELETE /api/tokens/{id}) every token above, whichever surface issued it.

    • 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 the documented routes plus the underlying Prisma models (e.g. Measurement, Medication, MedicationIntakeEvent, MoodEntry, User, DashboardLayout, ApiEnvelope, ApiError).
  • paths — the client-facing REST surface. Not every src/app/api/**/route.ts is in the contract: most /api/admin/* routes, the OAuth connect/callback legs, and the webhook surfaces are not documented here. The Retired tag lists removed paths that answer 410 Gone.

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. Change the Zod schemas and their .meta() registrations under src/lib/openapi/ (registry entry plus the matching module in src/lib/openapi/routes/). Keep operationId camelCase and stable; the iOS codegen keys off it.
  3. Run pnpm openapi:generate and commit the regenerated openapi.yaml alongside the schema change. CI's openapi:check fails on drift.
  4. Never edit the YAML directly and never bump info.version by hand; the version follows package.json at generation time.
