## AI Review
## Summary
The video confirms Issue #10409. The QA engineer navigates to the Workflows sidebar menu as described in the reproduction steps. Upon opening the menu, a workflow file is visible, but it lacks a file extension, confirming the reported UI regression.
## Confirmed Issues
### Workflow Sidebar Menu missing file extensions
`LOW` `00:08` `Confidence: High`
The Workflow sidebar displays filenames without their associated file extensions (e.g., `.json` or `.png`). The issue reporter noted this obfuscates workflows from other file types. In the video, a file is listed simply as "test_workflow" instead of "test_workflow.json".
**Evidence:** At 00:08, the user clicks the "Workflows" icon in the left sidebar. The panel opens, and under the "Browse" section, an entry labeled "test_workflow" is visible. No file extension is displayed.
**Suggested Fix:** Update the sidebar tree component to include the file extension in the display label for files.

## Possible Issues (Needs Human Verification)
None observed. The video is very brief and focuses specifically on the reported sidebar issue.
## Overall Risk
`low`
This is a purely visual UI regression that does not break core functionality (loading/saving), but it negatively impacts user experience when managing multiple file types within the workflow directory.
## Verdict
{"verdict": "REPRODUCED", "risk": "low", "confidence": "high"}
