CydandClaude Fable 5 f25abf1da5 BT410 5.3.130: the cockpit was shaking the wrong way -- a sign bug in the gyro torque, and a decode that stays unlanded on purpose
Re-reading landed code against the decomp turned up a real defect.
Gyroscope::ApplyDamageTorque (binary @004b2de4) finished with
Vector3D::Negate, which flips all three components; the binary negates
ONLY x in place after zeroing y.  So the z component of the body force
has carried the wrong sign on every damage shake and every collision
crunch since that function landed.  Fixed.  Flagged for the same
treatment: ApplyVerticalImpulse ends with bodyForce.y = bodyForce.x,
which wants its binary address found and checked.

The other half of the sitting is a decision NOT to land something.  The
master perf's second census (@0049fe80) computes three damage means into
mech+0x354/8/c -- over the hull zones, over every subsystem's private
zone, and over the myomers' private zones (the same 0x51155c GUID the
mobility scan proved).  A reader hunt found none: the apparent hits are
on OTHER objects at the same offsets, the gyro's damage multipliers and a
myomers cell, which is a good reminder that a bare offset grep proves
nothing when offsets are per-class.  No attribute row binds them either.
Landing it would be three loops feeding dead memory, so it stays decoded
and recorded until a consumer turns up.

Regression soak: mobility scan, telemetry and drive all unchanged, zero
faults.
