NutrientIntakeDay's composite primary key gains `source` (migration 0249_nutrient_intake_day_source): a manual water entry and the Apple-synced day total now live as two rows instead of the manual write being silently clobbered by the next Apple last-writer-wins sync. Every existing row already defaults to source=APPLE_HEALTH, so the migration is a pure PK-constraint change with no data rewrite. - POST /api/nutrients/batch keeps writing the APPLE_HEALTH row, byte-identical upsert semantics against the wider key. - GET /api/nutrients sums amounts within (nutrient, day) across sources before folding into the window summary. - POST /api/nutrients/water (new): manual water quick-add, add/set modes against the MANUAL row only, module-gated, rate-limited, idempotency-key aware, hard-evicts the dashboard snapshot cache. - GET /api/nutrients/daily (new): dense per-day series for one nutrient (summed across sources) plus the EFSA reference resolved against the caller's profile sex — omitted when sex is unknown. - catalog.ts gains resolveNutrientReference(), the sex-resolution helper both new routes and the insights cards share. docs/api/openapi.yaml regenerated for the two new routes.
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.
