Render a small JPEG preview for each stored document and show it at the card's leading edge, falling back to the kind icon when none exists. - Generate previews in the background on upload (new document-thumbnail pg-boss queue) plus a boot-time corpus backfill for existing documents; upload never blocks on or fails because of it. Images are downscaled via @napi-rs/canvas, a PDF's first page is rasterised then downscaled, every other type is skipped. Generation never throws. - Store the preview encrypted at rest in a 1:1 DocumentThumbnail side table (migration 0236) so the list/detail queries that omit the original blob never drag the preview either. Same AES-256-GCM string codec + fail-closed decrypt as the content index; wired into the key-rotation walk. - Serve it through an owner-scoped GET /api/documents/inbound/[id]/thumbnail (auth + module gate + userId-scoped query + fail-closed decrypt), always image/jpeg + nosniff + private, no-store; 404 on miss. The card renders an authed lazy <img>, onError falls back to the icon. - Add hasThumbnail to the document DTO so the card only fetches a preview that exists. Also drop the "search looks inside your documents" caption from the overview (the index-all prompt stays) and the per-card searchable marker; both were noise. Remove the now-unused i18n keys across all six locales.
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).
