Three defects in the bounded document reader. Image uploads were decoded into their thumbnails in the server process. A header check is all that stood between a decoder and an allocation the file chooses, and the GIF check showed how that fails. The image is now decoded in the same child process PDFs run in, under its memory ceiling and time limit; the header check stays in front of it. The reader's one slot went to whoever asked first, and a waiting item waited without end, so a few heavy PDFs from one account held everyone's lab scans behind them. The slot now goes to a read a person is waiting on before background work, to accounts in turn, to a few waiting items per account, and an item that waits past its lane's deadline is answered busy, which callers treat as retryable. Any child that ended without an answer counted as a document past its limits, so a kernel kill caused by the container's overall memory marked a good PDF as permanently failed. Only a bound the reader measured (the sampled memory, the time limit, the child's heap cap) is final now; any other end is run once more and then answered interrupted, which the thumbnail job retries within its ordinary attempts.
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.
