A. KNOCKDOWN PACING: the 0.4s gBlockCooldown contact-hysteresis is gone. It suppressed the crash knockdown for as long as contact was held, letting the kinematic drive re-slam the obstacle at full commanded speed EVERY FRAME -- continuous full-price crash self-damage, a healthy 65-tonner dead in ~2-3s of grinding (the night-7 SAURON ram death, 110 priced frames at |v|~34.7). The binary needs no guard (crash threshold @0x4ab178 read from the exe = 0.0, dispatch per blocked frame is authentic): the bmp clip zeroes the drive, and a pressed mech re-triggers the knockdown at v>6.3 long BEFORE its grind can price anything -- the type-0 divert's 0.5-pt free floor needs v>~18.5 at 65t. Wall grinding is free taps + paced staggers; only genuine fast arrivals pay. B. RAW RAM DISPATCH: the *0.001 "ram economy normalization" (2026-07-12) predated the #83 type-0 divert and became a double-normalization -- the victim's divert scale (~4e-5) compounded with it, so NO physically possible ram could clear the 0.5-pt free floor: rams were a no-op against the victim while the rammer's own un-scaled crash path rattled for real. The binary dispatches raw [T1 @part_012:15324]; the divert IS the normalizer. Also un-starves cultural-icon crunches (trucks now crush on contact per their authored armor, not after ~19 bumps). Bench (scratchpad/night7/mp_rampricing.sh): - wall leg: 150s full-throttle wall push = 125 paced knockdown binds (~1.2s cadence, iv2 40-43), 4767 crash frames ALL under the free floor, 0 rattle, 0 deaths (pre-fix: dead in seconds). - ram leg: BT_GOTO=enemy + BT_GOTO_STOP=2 rams the peer; raw amount arrives byte-identical on the victim (66239.1 tx == rx), victim prices 2.55 pts internal rattle (first ram damage to a victim in the port's history), pressed follow-ups free, 0 deaths both nodes, 108 knockdowns -> exactly 108 type-5 records on the observer (no skating regression). KB swept: combat-damage.md (the 1.3e6 moverMass mis-attribution corrected to the measured 60-90k tonnage scale), locomotion.md, rendering.md.

# 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)
