Marc-André Bombeck 9a29de4b02 feat(fhir): code illness conditions and lab observations
Close the three FHIR R4 coding gaps in the health-record export. Both are
export-layer only — no schema column, no migration, no contract change.

Illness Conditions now carry a broad SNOMED CT category concept per
IllnessType (infectious disease, allergy, injury, mental disorder, autoimmune
disease, chronic disease, with the generic Disease root as the fallback for an
unknown type) instead of the single generic placeholder. The user's own label
stays on code.text, the class on category.text, and the unconfirmed +
patient-reported guard rails are unchanged — the export still asserts no
specific diagnosis.

Lab Observations resolve a curated analyte to a real LOINC coding alongside the
user's code.text for the common biomarkers (HbA1c, lipid panel, ferritin, TSH,
vitamin D, creatinine, eGFR, ALT, AST, CRP, fasting glucose, hemoglobin), with
analyte-key and EN/DE alias normalisation. The canonical UCUM code is stamped
on the value only when the recorded unit matches the mapped canonical symbol;
an unmapped analyte or a non-matching unit keeps the honest text-only code and
display-only unit, never a fabricated code. The resolver takes an optional
canonical-name argument so a future Biomarker-catalog link can take precedence
over the free-text analyte without a further change here.

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.
