The status tier funnels every generation through runStatusCompletion, which reserves against the day's ledger before egress and reconciles after. The comprehensive briefing did not: the shared generator and the on-demand POST /api/insights/generate route both called the provider chain directly, so none of that spend reached coach_usage and no daily ceiling applied to it. Route every briefing provider call — first pass, JSON-shape retry, grounding-correction retry, and the daily paragraph re-roll — through one chokepoint that reuses reserveBudget / reconcileSpend and resolveDailyCap. The reservation lands after the consent gate, so a consent-blocked user is never charged, and a failed or timed-out call is refunded in full. Over-cap is a typed skipped outcome for the off-request generator (no upstream fault to retry against, so no failure marker and no retry enqueue) and a 429 for the on-demand route.
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.
