Two new self-report instruments join the mental-wellbeing engine on the existing PHQ-9 / GAD-7 infrastructure: - WHO-5 Well-Being Index: 5 items on the 6-point 5..0 scale over the last two weeks; the reported total is raw-sum x 4 (0-100) per the official WHO scoring (WHO/UCN/MSD/MHE/2024.1, CC BY-NC-SA 3.0 IGO). A total of 50 or below follows the WHO comment (below 50 = indication for further assessment). - Sleep Condition Indicator: 8 DSM-5-aligned items, 0-4 each with item-specific anchors, total 0-32, higher = better sleep; a total of 16 or below maps to the probable-insomnia range of the source publication (Espie et al., BMJ Open 2014;4:e004183, CC BY-NC, (c) Sleepio Limited). The instrument registry generalises rather than forking: per-item answer ceilings, option order/label schemes, recall-stem captions, a reported- score multiplier, score direction (higher-is-better inverts the follow-up threshold), per-instrument attribution lines, and the validated-item locale set are now instrument properties. Scoring stays server- authoritative; the create route validates the per-instrument answer ceiling and projects the total onto a COMPUTED WHO5_SCORE / SCI_SCORE measurement row (never client-attributable), which also auto-satisfies a planned screening reminder. Migration 0226 adds the enum values (additive, idempotent). OpenAPI regenerated. Neither instrument carries a self-harm item; the PHQ-9 item-9 crisis routing is unchanged.
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.
