The master perf's opening scan maxes the myomer chain's speedEffect into the mobility scale and applies it straight to the pilot's command cells: the throttle is multiplied by it, and a scale inside the 1e-4 deadzone zeroes the turn outright -- a mech with dead muscles cannot even pivot. It is the same cell the duck driver already read as "the legs still work", so that gate stops being a constant. THE CHAIN IDENTITY IS NOW PROVEN RATHER THAN INFERRED. My 5.3.122 note pinned mech+0x7ac to Myomers "by adjacency to the string pool", which nearly went wrong: the very cell the scan reads, +0x31c, is a MechWeapon trigger over in the weapon TU. The decisive evidence is arithmetic -- the Myomers cap-raise reads seekVoltage at +0x330 indexed by maxSeekVoltageIndex at +0x32c, and walking our own member order backwards from there lands speedEffect exactly on +0x31c. The ctor's myomer sweep also carries the other half: walking the chain is what sets the "I computed my own top speed" flag, so a mech WITH myomers broadcasts its cap and one without adopts the streamed value. Safe by construction against the obvious hazard: the mapper reassigns its demands from scratch in InterpretControls, which ticks before the mech's performance, so multiplying its cell in place cannot compound frame to frame. Soak: [mobility] scale 1 over 1 myomers on an undamaged bhk1 -- throttle unscaled, drive unchanged, zero faults. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
