Antiheld86 5ec361abec feat(measurements): mirror EXTERNAL in Zod, keep those rows correctable
Adds the `EXTERNAL_SOURCE` leaf beside `scopes.ts` and mirrors the value in
`measurementSourceEnum` so the read shapes and the sync decoder see it. It
stays out of `WRITABLE_MEASUREMENT_SOURCES`: a source a client could assert
would prove nothing about where a reading came from, and that constant is
published to clients as `ingest.writeAllowlist`.

The value-edit gate in `PUT /api/measurements/[id]` needs the other question
answered, though — whether the number is the user's own to fix — so it now
reads a separate `USER_CORRECTABLE_MEASUREMENT_SOURCES`. The 409 that
protects a Withings row exists because the value is the provider's reading;
the hardware behind an ingest token is the user's own scale, and locking
those rows would contradict what the settings card and the Home Assistant
guide promise. That is the only site reading the wider set.

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.
