Marc-André Bombeck 5619783648 Let a checkup be skipped or pushed back, and remember every outcome
Refs #223. A due Vorsorge item could only be done, deleted or ignored;
Telegram's postpone moved the date with no trace. Both decisions are
first-class now, and both are honest:

- POST /{id}/skip (no body): the interval restarts from the skip instant
  through the recurrence engine, lastSkippedAt is stamped, skipCount
  increments, any snooze clears. lastSatisfiedAt is NEVER touched — done
  and skipped stay distinguishable forever, enforced in the primitive and
  pinned by tests.
- POST /{id}/snooze ({until: YYYY-MM-DD}): the server resolves the day to
  the notifyHour in the profile timezone and moves snoozedUntil and
  nextDueAt to the same instant, so every due-state consumer follows
  without knowing snooze exists. At least tomorrow, at most five years.
- GET /{id}/history: the new append-only completion ledger
  (MeasurementReminderEvent), one row per satisfy from every engine path
  and per skip, onTime derived at write time against the due instant that
  was current when the event landed.

Two anchor fixes close the backdated-event gaps: the auto-resolve floor is
now the later of last satisfy and last skip (an old reading synced late no
longer resolves the cycle the user just skipped), and a backdated real
result re-anchors the next due at the later of its own instant and the
skip decision.

Screenings stay skippable and snoozable — the satisfy-side 409 guards
claimed fulfilment; a skip claims the opposite. Appointment reminders 404
on all three routes, in the lookup, like every by-id sibling. /checkups
gains the postpone sheet (quick chips, date field, the skip zone with its
own confirm) in both view branches, with muted meta lines and no card
colour change. The MCP preventive-care tool carries the resolved fields;
the OpenAPI contract publishes all three paths and the widened DTO.

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.
