CydandClaude Fable 5 e40abc86ea BT410 5.3.100: the collision economy -- armor is never touched by a crash, and the wall stops one-shotting the mech
The 5.3.99 open question is closed the way the binary closes it, not with a
divisor.  Two pieces:

THE DIVERT (damage hub @0x4a0368): type-0 Collision damage NEVER reaches the
armor zones.  Our handler was routing wall crashes through the same
cylinder-lottery path as enemy fire, which is why 24k-point kinetic numbers
one-shot vital zones.  The binary short-circuits them into

THE DISTRIBUTOR (@0049ffcc): the manual's "collision damage" technician
setting.  Gated on the owning player's advanced-damage flag; priced against
a 100 km/h reference impact --

    scale  = (2000 / mass) / (100 km/h)^2 / (1 - elasticity^2)
    amount = raw * scale;   under 0.5 the tap is FREE
    n      = Round(amount * 2) sub-hits of amount/n each

-- and applied as rattle crits to random INTERNAL subsystems (HeatSink /
Gyroscope / Torso families only), drawn by cumulative
collisionCriticalHitWeight against a [0,1) roll.  An un-won roll lands
nowhere; the binary does not normalize the weights, so neither do we.

LIVE, same arena mission as 5.3.99's four-death run:

    [colldmg] rattle 0.677919 pts in 1 sub-hits (scale=3.6e-05)
    [crash] BLOCK dmg=18831.1 iv2=711.428 KNOCKDOWN
    [crash] BLOCK dmg=331.878 iv2=12.549        (x6, pressed against a wall)
    deaths: ZERO (was four)

An 18.8k-point crash becomes 0.68 points of internal rattle; the low-speed
wall grind prices as free taps under the 0.5 floor; the knockdown stagger
still fires above the velocity threshold.  Walls now block, stagger, and
rattle -- they no longer execute.

Plumbing: MechSubsystem::CollisionCritWeight() accessor (the weight was
already streamed at +0x10C, protected), Mech::DistributeCollisionDamage
declared, random.hpp include.
