Marc-André Bombeck d2bad6943c perf(insights): route daily chart fetches through rollup buckets

The Insights trends row fires three parallel
GET /api/measurements?type=…&aggregate=daily&limit=5000 requests on
mount (BP_SYS / BP_DIA / WEIGHT). The legacy date_trunc path scanned
the measurements table each time — ~3 s per call on Marc's account.

Add a `source=rollup` opt-in on the listMeasurements schema. When set
alongside `aggregate=daily` the route reads from measurement_rollups
DAY buckets instead, swapping a full-table scan for a small indexed
read against the ~5 k-row rollup table. Cumulative HK metrics get
mean * count to reconstruct the daily SUM the chart expects.

The chart-data client opts in for every windowDays > 7 fetch so the
trends row + every sub-page chart benefit. When the rollup returns
zero buckets for the requested window the route falls through to the
live aggregate so brand-new accounts still render their first chart
correctly.

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.

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, Feedback, BugReport, 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:

Update the relevant route handler under src/app/api/**/route.ts.
Mirror the change in openapi.yaml. Keep operationId camelCase and stable — the iOS codegen keys off it.
Run npx @redocly/cli lint docs/api/openapi.yaml and resolve all errors. Warnings are tolerated when documented above.
Bump info.version if the change is breaking for clients.
