Build 3 settled it: the Lenovo TB330FU/A15 never spawns the UserService
(two 25s bind attempts, binder alive, permission granted). Build 4 falls
back to the legacy Shizuku.newProcess remote-process API via reflection
and records exec_path in the evidence — whether that path works per
device is itself the capability question core-shizuku needs answered.
Also archives both build-3 reports: phone 7/7 incl. provoked NEIGH
transitions in ip_monitor; traceroute.udp4 handled a silent hop ("*")
correctly on both devices.
