Let a user pick the Sensiplan double-check's second indicator — cervical mucus (default) or cervix observation — mirroring the published NFP standard where the temperature primary sign pairs with one chosen secondary sign. - `CycleProfile.secondarySymptom` (MUCUS default | CERVIX) drives which second sign the engine confirms against. Casual users keep temperature + mucus untouched; the choice lives behind the advanced cycle settings. - `CycleDayLog` gains the three standard cervix signs — position (LOW/HIGH), firmness (FIRM/SOFT), opening/os (CLOSED/OPEN) — as nullable columns (migration 0157), wired through Zod, the day-log upsert, the DTO, the sync feed, backup/restore and OpenAPI. Additive and back-compatible: existing profiles backfill MUCUS, existing day-logs keep NULL cervix signs, iOS inherits the fields. - The engine's `confirmSymptothermal` takes the secondary-symptom choice; on CERVIX it confirms against `detectCervixPeak` (last fertile-cervix day followed by three closed days — the cervix-closure rule) instead of the mucus peak. The double-check still requires BOTH the temperature shift AND the secondary peak: a single cervix sign never confirms, and the still-learning gate and conservative posture are unchanged. Engine derived clean-room from the Arbeitsgruppe-NFP / Raith-Paula & Frank-Herrmann standard.
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).
