- core/monitor.py: add fast metrics script (0.3s vs 1.4s sleep), collect() now defaults to fast=True for responsive UI - ui/workers.py: MonitorWorker changed from loop mode to single-shot (QTimer re-arms next cycle on finished signal, avoids paramiko blocking in infinite loop) - ui/widgets.py: remove debug print from _kick_one_sample - test_monitor_nonblock.py: fix sample counting by wrapping _on_sample instead of disconnecting signals (old approach missed new workers) - test_process_monitor.py: assertions account for MAX_RENDER_ROWS=200, fix MEM% column index (4 not 3) in sort test
