The snapshot gains the day's two readings with the age of the second one, through the same reader the page uses, so the page and the assistant cannot disagree about what today's comparison is. The freshness rule is the shared one: a comparison about the day before yesterday carries the date it is about and an instruction not to state it as today. Absence is a present field rather than a missing key — a model told "there is none yet" says so, and a model told nothing estimates one. The wording rule travels with the values, because a model handed a number and no instruction writes the sentence its training suggests, and about a forecast that sentence is a causal one. The contract publishes the resolved value: the expected figure, the band, the count, the deviation against the band, the age, and the contributions that carried weight. Nothing is left for a client to re-derive — two clients deriving the same figure about somebody's health record is how they start disagreeing about it. The description carries the observational wording and the display rule: the count goes wherever the value goes. The end-to-end proof runs against real Postgres and reads the table rather than a return value: nothing written a day short of the threshold, a banded and counted row on the day it crosses, the provisional label dropped at sixty days, the rows cleared when the module goes off, the rows cleared when entries are deleted back below the threshold, and an older pass's row replaced rather than left beside a fresh one. A delegate holding only the mind section is refused, and the assertion is on the response bytes.
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).
