## Implementation Complete ### What was implemented The milestone bulk actions functionality was already fully implemented: - Backend: POST /web/milestones/bulk endpoint at server/routes/web.py:1419-1475 - Frontend: JavaScript bulk action handler in server/templates/base.html:3957-3993 - UI: Bulk toolbar in server/templates/milestones.html:7-22 with checkboxes in server/templates/partials/milestones_table.html:57-58 ### What I added Comprehensive test coverage as required by the phase gates: **E2E Tests** (tests/e2e/test_milestones_bulk.py): - TestMilestoneBulkStatusChange: Tests for changing status of single and multiple milestones - TestMilestoneBulkAssignProject: Tests for assigning milestones to projects - TestMilestoneBulkDelete: Tests for deleting milestones (with cancel dialog handling) - TestMilestoneBulkToolbar: Tests for toolbar show/hide behavior, select all, and clear selection **API Tests** (tests/test_live_server.py::TestMilestoneBulkOperations): - test_bulk_status_change: Verify multiple milestones status update - test_bulk_assign_project: Verify project assignment - test_bulk_delete: Verify deletion of multiple milestones - test_bulk_no_milestones_selected: Verify 422 error handling ### Test Results - All 4 API tests pass - All 1077 core tests pass (excluding one pre-existing failing agent detection test unrelated to this change) ### Phase Gate Verification - [x] E2E test for each action (status, assign-project, delete) - [x] Bulk change status works - [x] Bulk delete works
