# Reports the CGEventTap chain and flags leaks.

# WindowServer walks every registered tap on every input event -- including
# disabled ones -- so a process that leaks taps degrades the entire input path.

# Healthy: ~10 taps total, 1-3 per process.
# Seen in the wild: Karabiner-Core-Service leaked 1029 taps over 14 days uptime.
