Marc-André Bombeck e216a9d678 feat(coach): warm, localized proactive nudge with opt-in AI enrichment
Rework the proactive Coach nudge so it reads like one human checking in on
another instead of a terse English alert.

Copy: the title is a name-led greeting that rotates day to day ("Guten
Morgen, …" / "Hey …"; the 05:15 frame makes a morning opener safe) and the
body is one calm observation plus a gentle invite — never an imperative.
Drop the verbatim quoting of the user's decrypted self-context sentence:
the focus is referenced only by presence, abstractly, and is no longer
decrypted at all. Remove the 80-char mid-word clamp; each channel composes
to a length budget instead.

Cadence: suppress the nudge when the user already talked to the Coach in
the last ~24 h. With the existing rolling frequency cap (never two in a
window) and the no-trigger-no-nudge rule, the surface stays anti-nag.

AI enrichment (opt-in via the coach prefs blob, default off): when a
provider is healthy the body is composed through the model under hard
guards — a per-user budget gate, a tight per-call timeout, a per-tick
ceiling so the sequential tick can't stall across the user base, and the
outbound safety screen on the output. Any error, timeout, budget refusal
or unsafe reply falls silently back to the deterministic template, which is
always the default and the fail-closed fallback.

Localized greetings, per-trigger bodies and the focus note across all six
locales; the prefs opt-in is surfaced in the notification settings.

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:

Preview locally

Open an interactive Redoc preview in your browser:

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

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.
