inotifywait watches writable paths in the SSH decky and mirrors any file close_write/moved_to into a per-decky host-mounted quarantine dir. Each artifact carries a .meta.json with attacker attribution resolved by walking the writer PID's PPid chain to the sshd session leader, then cross-referencing ss and utmp for source IP/user/login time. Also emits an RFC 5424 syslog line per capture for SIEM correlation.
