## QA PASSED See QA report document: 2ecd5716-db88-421b-b415-b3d1d8e54394 **All hypotheses tested and verified:** - Data attributes exist on status and project cells - Status dropdown shows correct options (planned/in-progress/complete/archived) - Project dropdown loads projects from API - Status changes save correctly to database - No modal interference - dropdowns work as expected **No issues found. Fix verified working.**

## Implementation Complete ### Changes Made 1. **Extended InlineEditManager in server/templates/base.html**: - Added milestoneStatusOptions array with planned/in-progress/complete/archived status options (lines 5884-5890) - Added projectOptions cache property and loadProjectOptions() async method to fetch projects from API (lines 5892-5928) - Modified handleCellClick() to detect both milestone and issue entities (lines 5970-5982) - Added createMilestoneDropdown() async method to handle milestone-status and milestone-project editable types (lines 6033-6068) - Added getMilestoneCurrentValue() to extract current status from cell (lines 6077-6096) - Added saveMilestoneValue() to PATCH milestone via API with optimistic updates and rollback on error (lines 6108-6161) - Added updateMilestoneCellDisplay() to update cell visuals after changes (lines 6170-6193) 2. **Updated milestones table in server/templates/partials/milestones_table.html**: - Added data-editable=milestone-status and data-milestone-id to status cell (line 61) - Added data-editable=milestone-project, data-milestone-id, and data-project-id to project cell (line 63) - Removed hx-get attributes from editable cells so they do not open the detail modal ### Verification - All tests pass (1389 passed, 1 unrelated failure in test_agent_detection.py) - The implementation follows the same pattern as issue inline editing - Milestone status dropdown shows planned/in-progress/complete/archived options - Project dropdown dynamically loads from /api/projects and caches results ### Phase Gate - InlineEditManager works for milestones: DONE - Status editable: DONE - Project editable: DONE
