+## KC-4 — Unified task context menu + Live Activity + calendar event actions
+
+**Status:** In Progress (implemented & build-verified; Live Activity pending on-device test)
+**Reported by:** User
+**Area:** Tasks / Calendar / Widgets
+
+### Description
+Long-pressing a task (in any task list) should show a consistent menu:
+Pin · Date · Move · Priority · Tags · Add to Live Activity · Delete — and the
+actions must actually work. Long-pressing a non-subscription calendar event
+should offer Edit / Delete only.
+
+### Fix
+- New shared `TaskMenuItems` (KisaniCal/Views/TaskContextMenu.swift) used by the
+  Today timeline, Matrix (grid + Overdue/Later/Completed lists), and Calendar
+  day timeline. Added `TaskViewModel.setPriority`.
+- Live Activity (ActivityKit): `TaskActivityAttributes` (shared app+widget),
+  `LiveActivityManager` (start/update/end/toggle, iOS 16.1+), `TaskLiveActivity`
+  widget (lock screen + Dynamic Island), `NSSupportsLiveActivities` via project.yml.
+- Calendar events (non-subscription, writable only): Edit opens the system
+  `EKEventEditViewController` (`EventEditView`); Delete via `CalendarStore.deleteEvent`.

+
+### How to test
+1. **Menu parity** — long-press a task in Today, in a Matrix quadrant, in a
+   Matrix list (Overdue/Later), and in the Calendar day view. All show the same
+   7 items.
+2. **Each action** — Pin (row pins), Date → Today/Tomorrow/Next Week/Remove
+   (due date changes), Move (task changes quadrant), Priority (flag changes),
+   Tags (category changes), Delete (removed).
+3. **Live Activity** — tap "Add to Live Activity" → a banner appears on the Lock
+   Screen / Dynamic Island with the task title + countdown; tap again to end.
+   **Requires a real iOS 16.1+ device** (not visible in the Simulator).
+4. **Calendar events** — long-press a personal (writable) event → Edit opens the
+   system editor; Delete removes it. A subscribed/RSS event (F1, TV) shows **no**
+   menu.
+
+### Known limitations
+- Live Activity visuals only render on a physical device; the design is a first
+  pass (orange accent + timer) and can be refined.
+- Uses the iOS 16.1 `Activity.request(...contentState:...)` API (deprecation
+  warning on 16.2+, still functional).
