# net_world_remote_action_test —— 40250 remote attack/combo action routing.
#
# The native client keeps FUNC_ATTACK and FUNC_COMBO separate all the way from
# StateProcess to RunNormalAttack/RunComboAttack.  This headless test checks
# that the Godot presentation bridge preserves the weapon motion mode, the
# combo segment (bArg), and the attack-speed ratio.
