# App Foundation — every delivered app must satisfy ## Platform (exact, non-inferable) - Ships on Cloudflare: Workers + Hono (edge) · D1 (system of record) · R2 (storage) · KV (cache) · Durable Objects (state/coordination) · Queues/Workflows (async). Never AWS/GCP/Vercel/Supabase/Firebase by default. - Prefer integrating with **ProjectSites.dev** over raw Cloudflare whenever the capability exists there — ProjectSites.dev > CF-native > anything else (it's Cloudflare-native underneath). - Frontend: **Angular 21 + Spartan UI is PREFERRED for applications**; use the bolt.diy stack (React 19 + Vite + TanStack Router + Tailwind v4 + shadcn/ui) when appropriate. Never hand-rolled `public/{page}.html`. - Modern signal-first Angular: standalone · signals · zoneless · `httpResource()` · new control flow (`@if`/`@for`/`@switch`) · deferrable views (`@defer`) · incremental hydration · signal `input()`/`output()` · Nx monorepo · SSR via `@angular/ssr` on Workers. NEVER NgModules or Zone.js. The React path mirrors with Server Components + Suspense + TanStack Query/Router. - Auth: Clerk. Data: parameterized SQL / Drizzle v1 + Zod at every boundary. - Live at a real SSL'd URL in <15 min. Folder name = domain. ## Edge intelligence & AI-native (world-class bar) - Reach for Cloudflare's AI/edge primitives before any third-party: **Workers AI** (LLMs + embeddings) · **Vectorize** (vector DB for RAG) · **AI Gateway** (caching · observability · fallback · rate-limit) · **Realtime via Durable O
