The roadmap snippet uses createAuthenticatedFetch(authClient) but doesn’t indicate where authClient comes from. Since createAuthenticatedFetch requires an AuthClient (typically from createAuthClient(...) or AuthProvider’s created client), consider clarifying the snippet/text so it’s copy/pasteable and doesn’t imply authClient is a global.

In the runtime initialization example, authClient is referenced but never created/imported, so the snippet can’t be followed as-is. Consider adding the minimal createAuthClient({ baseURL: ... }) step (or note that you can pass AuthProvider’s client) so readers can wire createAuthenticatedFetch correctly.

SchemaRenderer does not consume a dataSource prop; it reads dataSource from SchemaRendererProvider context. As written, passing dataSource={adapter} won’t actually inject the adapter into expression evaluation / components, so the example is misleading. Update the snippet to wrap the tree in SchemaRendererProvider dataSource={adapter} (matching how the console uses it).

| **Metadata Layer Assessment: 100% — Full schema-driven architecture is supported.** |

The metadata table marks “Hot Schema Reload” as ✅ complete, but the codebase currently only provides manual cache invalidation (ObjectStackAdapter.invalidateCache() / MetadataCache.invalidate()); there’s no automatic change detection/watch mechanism. Consider downgrading this to partial or clarifying that reload requires the app to explicitly invalidate cache and trigger a re-render.

The auth capability table shows ObjectStackAdapter({ token }) / ObjectStackAdapter({ fetch }), but baseUrl is a required constructor field. Consider adjusting the examples to include baseUrl so readers don’t copy a config shape that won’t type-check/work.
