Marc-André Bombeck 8db7c71b0e fix(api): one helper for list pages, exact cut signal, total order
listPage (src/lib/http/list-query.ts) reads one row past the limit and
cuts it back, on top of the existing list-cap signal rather than beside
it. Every capped list now gets its page there, and every read passed to
it orders by something ending in the row id, so rows that share a sort
value cannot repeat or vanish at a page boundary.

- practitioners, vaccinations and encounters were cut at their take
  with no signal; they now answer meta.truncated and accept offset, and
  their web readers walk the pages instead of stopping at the first
- symptoms/events reported hasMore on a page that was exactly full; it
  is now true only when a row past the page exists
- the document list's hand-rolled limit + 1 goes through the helper
- security-activity answers an out-of-range limit with the 422 its
  published schema already promised instead of clamping it

list-page-guard binds every apiListSuccess route to listPage, forbids
hand-cut lists and length-derived hasMore, and requires the id
tiebreaker in every listPage read.

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.
