Marc-André Bombeck b59a78155b docs(api): publish the share link's PDF and FHIR downloads
Both routes were exempt from the contract as `shareLink` — "authenticated
by the URL credential, for a recipient with no account". That reason
holds for the page a person opens. It does not hold for two routes whose
whole purpose is to hand a practice a file it files into another system,
which is exactly the audience a contract has. `/c/{token}/d/{id}` was
published all along, one route away in the same tree.

Each entry states the gate it shares with the page, the frozen selection
it can never exceed, the flat 404 that covers every miss class including
a documents-only link, and the 20/h per-link bucket. The FHIR entry says
plainly that it is a download and not a REST face, and names the two
resource families the bundle deliberately omits.

The create-request description claimed "there is no FHIR or other
machine-readable face behind a share token", which stopped being true
when these routes landed. It now describes what a link actually serves
and records that the insurance leaf is refused outright.

The coverage guard gains the other half of its staleness check. It caught
an exemption for a route that had disappeared, and never the reverse — an
exemption left behind after the route was published, which is how these
two would have stayed on the list while the contract already carried
them. Break-proof: re-add either entry and it goes red naming 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.
