# Collision-pricing audit bench (2026-07-31) -- verifies the two fixes:
#   A. knockdown-paced crash economy (freshBlock hysteresis removed): a mech
#      held against a wall must STAGGER periodically and survive, not pay
#      full-speed crash price every frame and die in seconds.
#   B. raw ram dispatch (the *0.001 double-normalization removed): a fast
#      mech-vs-mech ram must land REAL internal rattle on the VICTIM
#      ([colldmg] on the victim's node), which was impossible before.
#
# usage: mp_rampricing.sh wall   (leg A: solo, arena, BT_GOTO beeline into a wall)
#        mp_rampricing.sh ram    (leg B: 2-node, BT_GOTO=enemy ram + observer)
