The medication detail's notification section decides between the server-side reminder switch and the client-managed chip on `notificationPrefs.medication.clientManaged`, read off `GET /api/auth/me`. That payload never carried the field — the preferences live on their own endpoint, which is not on the app-boot path — so the flag was `undefined` for every account: the chip never rendered, and a person whose phone owns the reminders was shown a switch that no longer decides anything. The write path and the dispatch gate were correct the whole time; only the web reflection was missing its end. The payload now carries the fully-resolved block from the same resolver the dedicated endpoint uses, so the two cannot disagree, and an account that never opted in reads `false` rather than absent. No extra query: the session already loads the row the column sits on. The pair guard over this payload gained the direction that could not see it. It asked that every published field has a reader; a reader with no field was invisible. It now also reads the response types clients declare for this endpoint and holds them against what the route publishes. A typed guard was tried first and does not work here — each consumer declares its own local interface, so the compiler checks every file against its own private claim and agrees with all of them.
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).
