Marc-André Bombeck a1dbd9c831 fix(medications): apply the post-opening clock only where a container has one
A supply container went EXPIRED 30 days after its first use no matter what
kind of container it was. That window exists because puncturing an injection
pen exposes its contents and the product information caps how long the rest
stays usable; a blister of tablets has no such limit, every tablet sits in
its own sealed cavity, and pressing the first one out says nothing about the
rest. The state machine never read `containerType`, so a tablet pack opened
five weeks ago had its remaining stock written off.

The clock now keys off the container kind. PEN and AMPOULE carry it: both are
a single sealed reservoir that the first dose breaches. BLISTER, INHALER,
BOTTLE and OTHER do not: their units stay individually sealed, or the
arrangement is simply unknown, and a fixed 30 days would be a number nobody
entered. The printed expiry still applies to every kind, so an unknown
container is not an unbounded one.

`computeExpiresAt` takes the kind too, so a clock-less container with no
printed date now persists no `expiresAt` at all and the daily expire scan
never sees it.

The per-item PATCH gains a way back out: `markAsFirstUseAt` accepts null and
clears the opening date, which is the correction a container needs after the
intake hook auto-opened it from a back-dated dose.

Also drops `daysRemainingInUse`. It had no caller anywhere in the tree and
its docblock described a chip that does not exist.

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:

Open an interactive Redoc preview in your browser:

Generate static HTML for sharing:

npx @redocly/cli build-docs docs/api/openapi.yaml --output docs/api/index.html

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.
