<objective>
Align the cloud frontend with the normalized API. Use `kind` for classification, `provider_item_id` for provider navigation, stable `id` for DocuVault row identity, and backend freshness as the only source of synchronization truth.

  <action>
    Replace legacy-shaped fixtures with realistic CloudItemOut objects containing distinct `id` and `provider_item_id`, `kind`, nullable metadata, and no `is_dir`. Add tests named `renders_kind_folder_and_file_in_shared_browser`, `folder_click_uses_provider_item_id_not_id`, `tree_expansion_filters_kind_folder`, `nested_tree_uses_provider_item_id`, and `stable_docuvault_id_remains_row_key`. Include duplicate display names with distinct IDs/references so tests cannot pass accidentally by name.

    Add opaque-reference fixtures containing `/`, `?`, `#`, `%`, spaces, and Unicode. Assert CloudFolderView only passes props/emits events through StorageBrowser and does not add another grid/tree implementation. Verify root sentinel remains `parent_ref=null` at the API boundary and nested folders pass their opaque provider reference unchanged through named Vue Router navigation and the API client's query serializer—never manual route-string interpolation.

    Add breadcrumb tests proving labels and navigation refs come from an explicit session-only lineage of visited `{name, provider_item_id}` folder nodes (or equivalent API-provided ancestors), not `split('/')` or any other parsing of provider references. Breadcrumb clicks must restore the exact stored opaque reference.
  </action>
  <acceptance_criteria>
    - tests fail against current is_dir and item.id behavior
    - fixtures omit is_dir and distinguish id from provider_item_id
    - root and nested provider navigation are both covered
    - StorageBrowser remains the rendered browser component
    - no test relies on provider-specific path reconstruction in Vue
    - reserved-character provider references survive route/query transport and breadcrumb navigation unchanged

Map `response.freshness.refresh_state`, `last_refreshed_at`, `error_code`, and controlled `error_message` into Pinia. Keep a request-in-flight UI state only if it cannot overwrite the last authoritative server state; after the response, render the server object verbatim. A successful cached browse response is not proof of provider synchronization.

    Remove `new Date().toISOString()` and any unconditional `fresh` assignment from CloudFolderView. On request failure without a server freshness payload, preserve cached items and prior last successful timestamp while showing a controlled client transport warning; never invent a provider refresh time.

    Replace all cloud `is_dir` checks with `item.kind === "folder"` and file checks with `item.kind === "file"`. Route and browse nested folders with `provider_item_id`; retain `id` for Vue keys, selection, and DocuVault metadata identity. Do not add an alias field, provider-specific mapper, alternate browser, or duplicate expand/collapse state. Keep CloudProviderTreeItem and CloudFolderTreeItem wrapped by TreeItem.vue.

    Use named-route objects for connection routing and keep `parent_ref` in serialized query/API state; do not interpolate it into a route path. Ensure folder references are encoded only by Vue Router/API query serializers, not manually concatenated or decoded. Maintain explicit session-only breadcrumb lineage from root to visited folders; never reconstruct hierarchy by splitting `provider_item_id`, because Drive/OneDrive IDs and DAV references are opaque. Preserve connection UUID routing from Phase 12. Remove dead compatibility logic in the same change.

  <acceptance_criteria>
    - no active cloud component references item.is_dir
    - every provider browse/navigation call uses provider_item_id for nested parent_ref

| T-12.1-12 | UI falsely reports provider synchronization | Server freshness mapping; no browser-clock evidence |

1. Demonstrate actual API-shaped fixtures fail current is_dir/item.id code.
2. Verify kind-based root and nested classification.
3. Verify provider_item_id navigation while id remains row identity.
4. Verify warning/refreshing/fresh server payloads and exact timestamps.
5. Search for legacy is_dir usage in active cloud components and run the focused frontend suite.

<success_criteria>
- Users can see folders/files returned by every normalized provider adapter.
- Folder clicks and tree expansion use valid provider references.
- Synchronization wording reflects backend state rather than HTTP status or client time.
- Shared StorageBrowser/TreeItem architecture remains unchanged.
