Marc-André Bombeck 773b943bde fix(documents): keep PDF reading alive on CPUs the canvas build skips
The arm64 musl build of the native canvas uses LSE atomics and RCpc
loads throughout, so loading it on an ARMv8.0 core such as the
Raspberry Pi 4 ends the process with SIGILL. The CPU gate only knew
the x64 AVX2 case, and pdf.js loads the canvas as soon as it starts,
so on such a host every PDF read died in the child: no text layer, no
index, and the manual read reported a busy reader.

The gate now also closes on linux/arm64 under musl when the CPU lacks
the atomics or lrcpc feature. A closed gate travels to the PDF child,
which refuses to resolve the canvas module, so pdf.js carries on
without it and the text layer reads; rendering and thumbnails keep
their existing fail-soft path. A child that ends without an answer
now logs its exit code and signal.

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.
