Add the TOTP enroll/confirm/disable surface and Argon2id-hashed recovery codes as the v1.23 second factor. - totp.ts wraps otpauth (zero-dep) pinned to the interop floor (SHA-1, 6 digits, 30 s) with a +/-1 drift window. Replay protection persists the last accepted time-step per account (User.totpLastStep, migration 0202_v123_totp_laststep) and rejects any step that is not strictly newer, so a captured code dies the instant it is accepted once. - recovery-codes.ts issues ten single-use, high-entropy codes, Argon2id- hashed at rest, shown once; regeneration replaces the entire prior set in a transaction and verification burns the matched code with a guarded update. - The TOTP secret is stored AES-256-GCM encrypted (already registered in the encrypted-columns registry + rotation script); decrypt is fail-closed. - Routes: setup (pending secret), confirm (activate + issue recovery codes), disable (step-up + current factor), recovery-codes/regenerate (step-up). Setup/confirm are cookie-only; disable/regenerate add requireFreshMfa. - scripts/disable-mfa.ts is the operator escape hatch for a locked-out self-hoster, audited, run via pnpm dlx tsx.
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).
