Replace placeholder sandbox provider icons with official brand assets:
- Docker: white whale SVG on brand blue (#1D63ED) background
- E2B: official PNG logo via CSS module
- Local: Dify-branded SVG icon (SandboxLocal)
Add a component-level regression test for variable inspect artifacts tab:\n- verifies selected file path is used before reset\n- verifies stale selected path is dropped after files are cleared\n- verifies download url query call keeps retry disabled in this component
Problem:\n- In variable inspect artifacts view, clicking Reset All invalidates sandbox download query keys.\n- If a previously selected file has been removed, the download-url query may still refetch with stale path and return 400.\n- Default query retry amplifies this into repeated failed requests in this scenario.\n\nSolution:\n- Extend sandbox file invalidation with an option to skip download query refetch.\n- Use that option in Reset All flow so download-url queries are marked stale without immediate refetch.\n- Derive selected file path from latest sandbox flat data and disable download-url query when file no longer exists.\n- Disable retry only for artifacts-tab download-url query to avoid repeated 400 retries in this path.\n- Align tree selectedPath with derived selectedFilePath and add hook tests for invalidation behavior.\n\nValidation:\n- pnpm vitest --run service/use-sandbox-file.spec.tsx
Extract SearchResultRow component with useDelayedClick to match file
tree behavior (single-click preview, double-click pin). Subscribe to
derived boolean instead of raw activeTabId to avoid unnecessary
re-renders across all rows.
Replace the tree-filtered search with a flat list that shows icon + name
on the left and parent path on the right, matching the Figma design.
Clicking a file opens its tab; clicking a folder clears the search and
reveals the folder in the tree.
Remove isFocused ring style from TreeNode since focus-visible already
handles keyboard focus indication. Add rowClassName="outline-none" to
suppress the default browser outline on react-arborist row containers.
Add editorAutoFocusFileId state to automatically focus the editor when
a new text file is created. Improve tree-tab synchronization by adding
syncSignal/isTreeLoading guards, deduplicating rAF calls, and skipping
redundant select/openParents operations when the node is already active.
Enable PDF files to be previewed directly in the file content panel
instead of showing as unsupported files requiring download. Uses the
existing react-pdf-highlighter library with zoom controls and keyboard
shortcuts (up/down arrows).
Add "Import skills(.zip)" option to root-level context menu and sidebar
add menu with a question mark tooltip showing usage hint. Update menu
item labels and icons for consistency with design.
