+## Deployment flags in the browser
+Client code inside a workspace reads `hosted`, `billingEnabled`, `chatEnabled`, and the enterprise feature set through `useDeploymentShape()` (components) or `getDeploymentShape()` (block conditions, stores, helpers) from `@/lib/core/config/deployment-shape`, never the `isHosted`/`isBillingEnabled` constants from `env-flags`. Those constants freeze at module init from the root layout's `NEXT_PUBLIC_*` transport, which Next's bare 404 shell and `global-error` never emit, so a tab recovered from one would render Sim Cloud as self-hosted. The reader is seeded from the server-resolved workspace host context. Server code keeps reading `env-flags`.
+
 ## Package Manager
 Use `bun` and `bunx`, not `npm` and `npx`.

 - **Package Manager**: Use `bun` and `bunx`, not `npm` and `npx`
 - **Type-checking**: Run `bun run type-check` (per workspace) or `bunx turbo run type-check` (all of them). Do not remove the `@typescript/native` alias from the root `devDependencies` — nothing imports it, but it is what makes a bare `tsc` resolve to the native TypeScript 7 compiler instead of the ~10x slower JavaScript TypeScript 6 one that `@typescript/typescript6` pulls in transitively. `bun run check:native-typecheck` enforces this
