Release summaries
example-shared-ui-nested-shell
Document the example shared UI shell contract for nested-safe embedded previews.
maintainer
Maintainers now have release guidance that TemplateShell, NestedCommandShell, and SpecDrivenTemplateShell are content-scoped preview shells and must not recreate app-level AppShell, SidebarProvider, fixed sidebars, or global navigation inside embedded previews.
integrator
Example preview integrators can import TemplateShell or NestedCommandShell from the root package or documented subpaths and use bounded preview actions, sidebars, command search, and navigation while preserving host-app navigation ownership.
runtime-backed-core-template-previews
Ensure runtime-backed core template previews mount TemplateRuntimeProvider before rendering.
customer
Opening runtime-backed core templates such as `messaging-app` in the web sandbox now mounts the required local template runtime provider before the preview components call `useTemplateRuntime`.
