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:
mcp-capabilities.md— the tool, resource, and prompt catalogue, the grounding contract, and the write model.mcp-skills.md— building a connector or skill on top of it.../self-hosting/mcp.md— enabling and connecting the surface (operator guide).

The spec is expected to be lint-clean (errors = 0). Some warnings are intentional:
no-server-example.com—http://localhost:3000is the dev server.operation-2xx-response/operation-4xx-response— webhook + redirect endpoints intentionally omit one or the other.no-unused-components—ReminderPhaseis exposed for client codegen even though no path response references it directly.

Conventions
- Successful responses use the envelope
{ data, error: null }. - Error responses use the envelope
{ data: null, error: '<message>' }. - Pagination uses
limit+offsetquery parameters and ameta: { 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:
- Update the relevant route handler under
src/app/api/**/route.ts. - Mirror the change in
openapi.yaml. KeepoperationIdcamelCase and stable — the iOS codegen keys off it. - Run
npx @redocly/cli lint docs/api/openapi.yamland resolve all errors. Warnings are tolerated when documented above. - Bump
info.versionif the change is breaking for clients.
