The admin "Delete all data" action carried its delete list inline. That list named nine tables, which was most of the schema on the day it was written, and it stayed at nine while the schema grew to a hundred and twenty-two models. Laboratory results, documents, cycle logs, journals, mood, workouts, sleep and Coach conversations all survived the wipe an operator runs before handing a box on, and the toast said it was done. The per-account wipe had the same defect and grew a derived plan for it. The admin route now reads that plan: ADMIN_WIPE_MODELS is WIPE_MODELS minus a single documented subtraction, so a model added to the schema lands in both wipes at once. - AccountGrant is the one difference, with its reason in the plan: it is the only access path to a managed profile, and this action preserves accounts by definition. Deleting every grant would leave records nobody can open, administer or delete. - The audit history now goes with everything else. It is a record of who did what from where, which is exactly what clearing a box is for; the receipt written after the transaction commits replaces it. - One transaction with the same budget as the account wipe. A half-applied wipe is worse than none, because the person is told it succeeded either way. - The result line reports rows and tables instead of nine fixed names, which is how nobody noticed: it read the same whether the wipe had cleared nine tables or ninety. Guards, both watched red before landing: admin-data-wipe-completeness.test.ts fails when a user-scoped model reaches neither the wipe nor a written exemption, and when the route names a table inline again. The integration guard seeds every table in the schema for two accounts, runs the route, and asks the database what is left — drop one model from the plan and it names the surviving table.
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).
