Replace the rebuild_guard context manager with a self-contained 3-layer architecture in treectrl/frame: 1. Paint suppression: suppress ALL tree paints during refresh with empty PaintDC (breaks the self-sustaining AUI cascade where each 280ms tree paint triggers GDK damage → child repaint → repeat). One clean Refresh() fires when __refreshing clears. 2. Per-widget idle lifecycle: each RefreshAllItems binds its own EVT_IDLE handler that monitors _dirty + one extra cycle, then clears __refreshing and releases the input filter. 3. Refcounted EventFilter: each widget acquire()s on rebuild start and release()s on idle completion. Last widget triggers a 1s deferred deactivation to cover the post-rebuild settling period. Also: - Remove rebuild_guard from viewer.refresh() and CalendarViewer.reconfig() - Remove dead code: rebuild_guard, _rebuild_guard_state, idle handler, contextmanager import from frame.py - Log all silent 'except RuntimeError: pass' via DEAD-OBJ prefix - Harden log_step() for Windows consoles (UnicodeEncodeError) - Replace em-dash with ASCII dash in log messages for portability - Use nonlocal instead of dict hack in sash throttle closure - Update LIST_MANAGEMENT.md with current architecture and 12 failed approaches
