RETRACTION + FIX: the myomer seek->speed coupling IS in the 4.10 binary --

restored byte-grounded; the morning's removal was export-gap blindness

Player testimony (Oracle, pod veteran: seek-4 humanoid = 182 kph -- the
manual's printed Super Charged figure; overheat = 'freezing up') forced a
re-audit of the morning's 'no dynamic myomer->speed feed' verdict.  The
verdict was WRONG: a raw-image capstone sweep for FPU reads of [reg+0x31C]
found the consumer inside the UN-EXPORTED master-perf region -- the same
decomp gap that hid the #93 crash block.  Decoded @0x4a9cf2-0x4a9da4 [T1]:

  per frame: MAX speedEffect@0x31C over the myomer chain (+0x7AC)
             -> mech+0x79C
             mapper->speedDemand@0x128 *= it        (the SPEED coupling)
             if |drive| <= 1e-4 (@0x4ab16c):
                 mapper->turnDemand@0x12C = 0       (the FREEZE)

Everything the manual + the veterans describe emerges: gear 4 rides
speedEffect ~1.43 into the RegisterMaxOutput gait cap (base x 1.4284 --
the two mechanisms interlock: 61.5 x 1.43 = 87.9 vs cap 87.8 measured) =
SUPERCHARGE; myomer heatFactor degradation slows you; overheat freezes
speed AND turn; damage slows (speedEffect carries 1-damage -- #75's
original premise was RIGHT and its 'falsified' close was wrong).

Restored in mechmppr.cpp, byte-grounded and better than the pre-removal
draft: MAX over the chain (was first-found), NO 1.0 clamp (the old clamp
ate the overdrive), turn-freeze included.  BTMyomersSpeedEffectOf
(unclamped) replaces the deleted BTMyomersDriveOf.

Verified live: healthy drive=1.0 (no speed change), collision-rattled
myomers drive 0.999 -> 0.892 -> 0.742 with demand scaling in lockstep
(61.5 -> 54.9 -> 45.7).

KB corrected in place (subsystems WAVE 6, pod-hardware manual audit
retraction, open-questions resolved) + NEW GOTCHA #21: export-gap
blindness -- 'no callers in the decomp' is not 'no callers in the
binary'; sweep the raw image for the operand pattern before declaring a
data path dead, and when a primary source disagrees with your decomp
sweep, suspect your evidence first.
