# 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.
# Symptoms: unstable FPS, and three-finger Space swipes becoming very laggy
# (highest event rate = worst case).
#
# Healthy: ~10 taps total, 1-3 per process.
# Seen in the wild: Karabiner-Core-Service leaked 1029 taps over 14 days uptime.

CLAUDE.md is now the SUPERSET for every machine, with a # Scope section at the end listing what each machine omits. A machine's copy = this file minus its omitted rules minus the Scope section. Current scope: home omits
