The five hand-written registrars (about 5,500 lines, one 997-line function) are replaced by `jobs/registry/`: one `defineJob` entry per queue with its cron, schedule send options, policy, work options, lock, lane and a handler loader. `registerJobGroup` creates, schedules, retires and binds each group in the order the registrars used; the worker boot walks the groups and runs their boot discovery. Handlers load on their queue's first job. The facts a declaration needs at boot (names, crons, concurrency, send options) moved out of the heavy job modules into light `*-queue.ts` siblings, and their importers point there, so loading the registry evaluates 288 modules instead of the 1,164 the registrars pulled in. The formerly inline handlers moved verbatim into handler modules under `jobs/reminder/`. Fitbit's queues live in `fitbit/jobs/definitions.ts` and enter the registry through one spread, so removing the integration later is that folder and that line. `tests/integration/queue-registration-parity.test.ts` proves pg-boss holds exactly what the registrars left (queues, schedules, bindings, byte for byte) and loads every handler once. The queue tests and the runtime guard assert on the registry objects instead of reading registrar source.
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.
