+docs(skills): the objectui project-setup guide names where uploads live now that `@object-ui/providers` is gone
+
+Clause-②: no
+Metadata-protocol: none
+
+- **Before.** `objectui/guides/project-setup.md` sent a third-party app to `@object-ui/providers` for `UploadProvider` / `useUpload`, in the provider-stack list and in the decision matrix. That package is retired and gets no further release.
+- **Now.** `UploadProvider` / `useUpload` come from `@object-ui/fields`; the ObjectStack storage adapter `createObjectStackUploadAdapter` comes from `@object-ui/data-objectstack`; the `UploadAdapter` / `UploadOptions` / `UploadResult` contract is `@object-ui/types`'s, re-exported by `@object-ui/fields`.
+- The troubleshooting section drops two monorepo-only tips (the Turbo cache block and the "downstream packages need built `dist/`" line), which a third-party app consuming published packages never needs.
+- No schema, key or behaviour changes.

 ### Module not found errors
 - Run `pnpm install` to ensure workspace links are resolved
-- Run `pnpm build` — downstream packages need built `dist/` directories
 - Check `tsconfig.json` path aliases match project structure
 
-### Turbo cache issues
-- `pnpm turbo run build --force` to bypass cache
-- Delete `.turbo/` directory for clean state
-
 ### Vite HMR not working
 - Check `vite.config.ts` has `react()` plugin
 - Ensure file extensions are `.tsx` not `.jsx` when using TypeScript
