Marc-André Bombeck aadc3a8e89 feat(api): carry the score's basis on every surface that carries the score
`scoreBasis` rides the composite, the dashboard snapshot's flattened hero
block and the daily digest's score. It says how many distinct areas of
health the number counted, how many the method recommends, which tier that
lands in, and whether any counted pillar was a physiological measurement.

Optional everywhere, because two of the three surfaces are served out of a
cache and a payload written before this release cannot grow a field. The
snapshot and digest blocks have taken six additive fields this way already;
this is the seventh.

Resolved on the server for the same reason `configured` is. Counting
`composition` client-side would get it wrong more often than right — three
of the seven pillars share the cardiometabolic area, so a three-pillar
score can rest on one.

One shared component, `HealthScoreBasis`, declared once in the insights
schema module and referenced from the other two registry modules, rather
than three inline copies that drift the first time the block gains a field.
Declared through the assigning `.meta()` form: a bare `.meta()` statement
registers an instance nothing references, and the id then never becomes a
component.

The composite's `insufficient` reason narrows to the single value
`no_usable_data` and says so in the published description. That field is an
open string in the document, so the change is additive on the wire even
though the value space shrank.

The score-config 422 description drops the two retired reasons and states
plainly that the empty selection is now the only refusal, so a client does
not keep a three-area rule of its own in front of a write that no longer
has one.

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:

Validate

npx @redocly/cli lint docs/api/openapi.yaml

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 — 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 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.
