The CSV is written in the device's language, and the keys are translated along with the values: a German watch writes `Aufzeichnungsdatum` and `Klassifizierung`, not `Recorded Date` and `Classification`. Indexing on the English keys found none of them, so the parser never located the waveform and rejected the recording outright — a lost import, not a missing field. Two alias maps close it, both taken from real exports rather than from a dictionary: nine metadata keys and two verdicts, consistent across every German file observed. Adding a language is a data addition to those maps and nothing else. The verdict map is an indirection onto the English wording rather than a second verdict-to-enum table, so there stays exactly one place that decides what a verdict means. The other four shipped languages are absent on purpose. A wrong key silently mis-files a value and a wrong clinical verdict is worse than none, so an export this parser cannot place is refused — which an operator can see — rather than read into the wrong column, which they cannot. Two gaps are written down at the map: no observed file carries an average-heart-rate row in any language, and the paired layout's column header has only ever been seen in English.
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 renamedmiddleware). 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 inapiHandler. Seeapp/README.md.lib/— the server/runtime toolkit:apiHandler, auth, crypto, rollups, AI, notifications, pg-boss jobs, integrations, rate limiting. Seelib/README.md.components/— React components (shadcn/ui new-york, kebab-case files). Seecomponents/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 byprisma 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.
