 ## Context
 
-- **Current state**: v0.3 started 2026-06-17 after v0.2 shipped. The next focus is reimagining cloud storage as virtual-local document storage: connected cloud files should feel local to navigate and manage, while DocuVault adds classification and smart search without unnecessarily storing full cloud file contents.
+- **Current state**: v0.3 in progress — Phase 12 (cloud-resource-foundation) complete 2026-06-19. Provider-neutral CloudResourceAdapter contract, durable CloudItem/CloudFolderState ORM, connection-ID browse API, stale-while-revalidate Celery refresh task, and capability-aware StorageBrowser frontend all shipped. v0.2.0 released. Phase 13 (cloud mutations: create/rename/move/delete) is next.
 - **Tech stack**: FastAPI 0.136+ (Python 3.12), SQLAlchemy 2.0 async, Alembic, MinIO SDK; Vue 3 (Options API), Pinia, Vue Router 4, Vite, Tailwind CSS.
 - **Code quality**: v0.1 was built feature-first under time pressure. Both backend and frontend contain duplication, inconsistent patterns, and components that grew beyond their original scope. v0.2 addresses this systematically.
 - **Admin panel**: Standalone /admin/* route subtree with AdminLayout as the route component, AdminSidebar with 5 nav links, and 5 dedicated view components. AdminView.vue and legacy tab components deleted. Admin users redirect to /admin on login; non-admin blocked by to.matched.some() guard.
