The runtime import graph (static value imports and re-exports, side-effect imports, dynamic import() with a literal; `import type` erased) is built with the TypeScript compiler's module resolution under the `@/*` mapping, over every production module. No new dependency. - Cycles: 13, counted one per back edge of a sorted depth-first walk (the number `madge --circular` reports), in 7 strongly connected components: the audit/geo/notifications/managed-profiles cluster (10 modules), the compliance facade cluster (9), command palette ↔ store ↔ shortcuts, modules ↔ cycle gate, boss-instance ↔ boss-ready, mood aggregates ↔ patterns, features ↔ signals-of-day. A new component or a component that draws in another module fails whatever the count says; a lower count or a shrunk component fails until written back. The target is zero. - Re-export-only modules (every statement an `export … from`): 16 listed; a new one fails. Proof: two planted modules importing each other failed with "lib/zz-probe/a.ts <-> lib/zz-probe/b.ts", a planted `export * from "./a"` module failed the re-export ratchet, and a baseline raised to 14 cycles failed with the write-back message until RATCHET_WRITE=1 restored it.
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.
