## Implementation Summary Added E2E test file tests/e2e/test_update_issue_priority_to_medium.py with 5 test cases: 1. test_update_issue_priority_from_low_to_medium - Upgrade from low priority 2. test_update_issue_priority_from_high_to_medium - Downgrade from high priority 3. test_update_issue_priority_from_urgent_to_medium - Downgrade from urgent priority 4. test_update_issue_priority_from_none_to_medium - Assign medium priority to an issue that has no priority set 5. test_update_issue_priority_to_medium_reflects_in_table - Verify table UI updates after changing priority Technical Notes: - The API requires a valid priority value when creating issues - To test from none to medium, we first clear priority to none via UI, then set to medium - Tests follow existing patterns from test_update_issue_priority_to_low.py All 5 tests pass against local server with debug mode enabled.
