## QA PASSED See QA report document: 6da88981-b1d0-498d-9058-34e001f0e110 **All tests passed:** - Empty assignee support - PASS - Concurrent edit prevention - PASS - Keyboard shortcut conflicts prevention - PASS - HTMX refresh handling - PASS - No critical console errors All phase gate requirements verified. Fix works as intended.

## Fix Summary Enhanced InlineEditManager with the following error handling and edge case improvements: ### Changes Made 1. **Concurrent Edit Prevention** (server/templates/base.html:6051-6054) - Added isSaving flag to block new edits while a save is in progress - Prevents race conditions when users click multiple cells quickly 2. **HTMX Refresh Handling** (server/templates/base.html:6029-6041) - Added htmx:beforeSwap event listener to close dropdowns before DOM updates - Added htmx:beforeRequest handler for table refresh scenarios - Prevents orphaned dropdown elements when table content changes 3. **Empty Value Support (No Assignee)** (server/templates/base.html:6103-6156, 6196-6199, 6227-6229, 6307-6309) - Added assignee case to createDropdown with dynamic option generation - Added getAssigneeOptions() method that builds options from existing assignees - No assignee option sets value to empty string which converts to null for API - updateCellDisplay() shows dash for empty assignee values 4. **Keyboard Shortcut Conflicts Prevention** (server/templates/base.html:3462-3469, 3514-3516, 5995-6001) - Added isDropdownOpen() method to check if inline edit is active - Updated global keyboard shortcut handler to check isInlineEditOpen - Shortcuts are now blocked when inline edit dropdown is open ### Testing Results - All server tests pass (114 tests) - All CLI tests pass (126 tests) - No regressions detected ### Phase Gate Verification - Network errors show toast + revert (already implemented in original code) - Concurrent edits blocked (via isSaving flag) - HTMX refresh closes dropdown (via htmx:beforeSwap handler) - Empty assignee works (via getAssigneeOptions with No assignee first)
