Update report.md to reflect completed work: add ✅ DONE markers to Issue C1, C2, and C3 headings; mark corresponding items 1,2,4,5,10 in the Priority Action List as completed; expand details for ConditionalGlassButton (unreachable #available branch removed) and Calendar API replacement (note remaining NSCalendar casts in some computed properties). These edits clarify current status and remaining cleanup tasks.
