The Coach page gets a conversations panel on the right of the thread. From 1280 px it docks beside the thread and slides open and shut; the reading column keeps its width either way and only its centring moves. It is open on a first visit and remembers the last choice per device. Below 1280 px it is a sheet from the right. The toggle sits at the trailing edge of the top bar, through a small page-owned slot the top bar now renders. The panel lists every conversation grouped by recency, with a row menu to rename in place (Enter saves, Escape cancels without closing the panel) and delete with the existing undo toast. The undo window now survives the sheet closing. New chat is the round button at the panel's bottom right, and picking or starting a conversation keeps ?c= in the URL. The gear in the panel header opens quick settings: a popover from md up, a bottom sheet on a phone. It switches the answering provider (chain reordered through the existing route), the model and reasoning level where the person owns them, and shows what the Coach can see. Keys, the Codex sign-in and the fallback chain stay in Settings > AI. The drawer's gear opens the same overlay. The composer's + menu is gone. Settings > Coach links to /coach?settings=data, which opens the overlay on what the Coach can see instead of a rail that no longer exists.
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).
