Marc-André Bombeck 984a75d036 fix(api): name the private-origin refusal on webhook and ntfy routes
The save routes evaluate the same policy the senders do. A target on a
private network the operator has not listed is a 422 with
meta.errorCode = private_origin_not_approved and a message that names
NOTIFICATION_PRIVATE_ORIGINS, instead of the generic "Invalid data"; a
listed private address saves although the plain public floor would
have refused it. The settings schemas take the target predicate as a
parameter so the validator module never reads the environment; the
exported constants keep the public floor for the OpenAPI contract.

The test routes forward the sender's refusal as the same 422 and code
instead of a bare 500, so the card can say why the test failed rather
than sending the operator to the wide-event log. A delivery fault is
still a 500. Both test routes and the dispatcher reach the same sender
function, and a structural test holds them there.

The OpenAPI descriptions name the code on all four routes; the test
button's error map gains the code in every locale.

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.
