Marc-André Bombeck 09446846b1 Refuse an export nobody scoped, and stop naming UCUM without a code
Two findings from the deferred-audit list, both live since July.

A FHIR lab quantity stamped the UCUM system unconditionally while the
code was only added when the analyte map resolved a symbol for exactly
that unit. A receiver was told the unit came from UCUM and then handed
no UCUM code, which is a coding claim the bundle cannot back. System
and code now travel together, on the value and on both reference-range
bounds.

The doctor-report export accepted a selection that admits nothing. The
panel disables its own submit in that state, so only a hand-built
request reached it, and it rendered an empty artefact while spending a
rate-limit slot. This route has no documents-only mode that would make
an empty leaf list a legitimate scope, so it refuses with 422. The
share-link route, which does have that mode, is untouched.

src/

Application source. HealthLog is a Next.js 16 App Router project (output: "standalone", React 19, TypeScript strict). The path alias @/* resolves to this directory. Everything a request touches lives under here; the layout below follows the request flow rather than alphabetical order.

Request flow

client → src/proxy.ts → src/app/<route>/route.ts → src/lib/api-handler.ts → handler body → src/lib/api-response.ts → client
  • proxy.ts — the HTTP edge (Next.js 16's renamed middleware). Public-path allowlist, demo-mode mutation block, server-side onboarding redirect, worker-only refusal, x-request-id + CSP nonce generation, every security header.
  • app/ — App Router pages (RSC by default) and API routes. Every API route wraps its handler in apiHandler. See app/README.md.
  • lib/ — the server/runtime toolkit: apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. See lib/README.md.
  • components/ — React components (shadcn/ui new-york, kebab-case files). See components/README.md.

Other directories

  • hooks/ — shared React hooks (use- prefix, kebab-case).
  • types/ — shared TypeScript declarations.
  • generated/prisma/ — the generated Prisma client (do not edit; regenerated by prisma generate). Imported as @/generated/prisma.
  • instrumentation.ts — Next.js startup hook; boots the pg-boss worker registry and boot-time backfill queues.
  • __tests__/ — cross-cutting unit tests; most tests live in __tests__/ folders next to the code they cover.

Conventions

See ../CLAUDE.md for the full set. The load-bearing ones: RSC by default ("use client" only when a hook/state/browser API needs it); every API route wraps apiHandler and parses its body with Zod safeParse; userId is always narrowed from session or Bearer, never accepted as a body field; TanStack Query keys come only from src/lib/query-keys/; outbound HTTP goes through src/lib/safe-fetch.ts.
