Remove border-right on Start tab and border-bottom on tab bar when no
file tabs are open, making the tab area blend seamlessly with the
content area below.
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.
