169 of 364 mutating handlers met no rate limit, every PATCH and DELETE on an [id] among them. The shared per-account write bucket (300 a minute, keyed on the acting account) was called by hand in a dozen creates; it is now charged by the identity resolvers for any POST, PUT, PATCH or DELETE, once per request, so a route is metered by resolving its caller. The bulk ingest routes the native client syncs through in bursts (measurements, workouts, intake, mood and cycle bulk, nutrients, the ECG sweep) declare writeBucket: "own" and keep their dedicated ceilings, so a large HealthKit backfill cannot lock the person out of logging a dose. A read-over-POST stays free. write-rate-limit-guard fails on any mutating route that neither resolves its caller through a metering resolver nor calls a limiter, unless it is on a short reasoned exception list; an opt-out must be on its own reviewed list and call its own limiter.
src/app/
The Next.js App Router tree: the page surfaces a logged-in user sees and the REST API under api/. Server components are the default; "use client" is added only where a hook, state, or browser API needs it. Routing is file-based — a page.tsx is a page, a route.ts is an API endpoint.
API routes (api/)
Every endpoint wraps its handler in apiHandler (@/lib/api-handler), parses any body with Zod safeParse, narrows userId from the session or Bearer token (never from the body), and returns the { data, error, meta? } envelope. requireAdmin() is cookie-only, so api/admin/ is unreachable by Bearer token. Notable groups:
auth/— login, register, password, passkey (WebAuthn), refresh, Codex device-OAuth.measurements/,mood-entries/,medications/,sleep/— the core health-data CRUD + batch/bulk ingest.ingest/— external Bearer-token ingest surfaces.insights/,analytics/,dashboard/— AI insights, the Coach SSE stream, trend summaries, the first-paint dashboard snapshot.withings/,whoop/,fitbit/,integrations/,sync/— OAuth connect/sync/webhook surfaces and the offline delta feed.fhir/,share-links/,doctor-report/,export/,import/— clinician-facing FHIR R4 read API, shareable records, report + data export.notifications/,devices/,send/,telegram/— channel registration, device tokens, dispatch, webhook intake.admin/— operator panel APIs (cookie-only).health/,version/,meta/,internal/— health check, build-version probe, runtime metadata, worker-internal routes.
Page surfaces
measurements/, medications/, mood/, insights/, achievements/, notifications/, settings/, onboarding/, admin/, plus the public about/, privacy/, bugreport/, the share-record route c/, and the root dashboard (page.tsx). Shared shell + chrome lives in layout.tsx; error.tsx / global-error.tsx / not-found.tsx / loading.tsx cover the framework boundaries. layout.tsx holds the one nonce-bound dangerouslySetInnerHTML (theme bootstrap).
