## QA RE-VERIFICATION PASSED Second independent QA verification performed by code-verification-qa agent. **Verification Method:** Comprehensive code review + build verification **Results:** - ✅ All 5 requirements verified - ✅ Code quality: EXCELLENT (accessibility, consistency, performance) - ✅ Build passes without errors - ✅ No regressions identified - ✅ All edge cases handled properly - ✅ Security review passed **Key Findings:** 1. Plus button properly implemented with hover visibility 2. Excellent accessibility (keyboard support, ARIA roles) 3. Proper event handling prevents conflicts with project navigation 4. Consistent with existing codebase patterns 5. Previous browser testing by qa-agent confirmed functionality **Build Verification:** ``` ✓ Compiled successfully in 13.3s ✓ Generating static pages (3/3) in 782.1ms ``` **Recommendation:** VERIFIED - Ready for production Full QA report: /tmp/qa-APLANE-20-verification.md

## Implementation Complete ### Changes Made **Files modified:** - `frontend/components/project-monitor-sidebar.tsx` - Added `onLaunchAgent` prop to interface and component - Added `hoveredProjectId` state for hover detection - Added Plus button to both active and archived project rows - Changed project rows from `<button>` to `<div role="button">` to avoid nested button HTML issue - Added keyboard accessibility (Enter/Space key handling) - `frontend/app/page.tsx` - Added `onLaunchAgent` prop to `ProjectMonitorSidebar` component ### Verification - Build passes successfully - QA agent verified using chrome-devtools: - Plus button appears on hover - Clicking Plus opens Launch Agent dialog - Project is pre-selected in dialog - Project row navigation still works (clicking outside the Plus button) ### Technical Details - Used `div` with `role="button"` and `tabIndex={0}` instead of nested buttons for HTML validity - Added keyboard event handler for accessibility (Enter/Space triggers project selection) - Reused same hover-visibility pattern as the agent kill button

## QA PASSED See QA report document: beabfe47-0cfc-44a6-999f-a6bc975fff5e **All tests passed:** - Plus button appears on hover in sidebar project rows - Clicking Plus opens Launch Agent dialog with project pre-selected - Project row click still navigates to project detail view - No regressions in existing functionality **Minor issue noted (non-blocking):** - Nested button HTML causes hydration warning - should be fixed in a separate ticket Fix verified working. Marking as done.

## Feature Triage Complete **Status:** NOT IMPLEMENTED **Summary:** The quick launch button (+) does not currently exist in the sidebar. The feature can be implemented by adding a Plus button to project rows in `ProjectMonitorSidebar`, following the existing hover-visibility pattern used for the agent kill button. **Implementation Location:** - `frontend/components/project-monitor-sidebar.tsx` - Add Plus button to project rows - `frontend/app/page.tsx` - Pass `onLaunchAgent` prop to sidebar **Complexity:** LOW (~20-30 lines of code across 2 files) **Key Patterns to Reuse:** - `projects-grid.tsx` Plus button pattern - Existing hover-visibility pattern from agent kill button - Existing `LaunchAgentDialog` component See attached triage report for full details.
