Claude (auto-RE) 850b04c606 re(flight): roll DOES depend on speed -- the withdrawal is reversed
Measured about the FORWARD axis (roll_axis.py), which is the fix the withdrawal
specified: express the new up-vector in the old (up, right) basis and take
atan2(u.w_old, u.u_old), so the component along forward -- what pitch produces --
is dropped by construction. The old probe watched a non-forward matrix row, which
sees any rotation that moves it, and that is why two different stick axes produced
the same numbers.

Stage 02, file pad, single-axis holds (lx=32767 with every other channel exactly
0, trigger held in the same write since the pad state is written whole), 5 s
settles, 8 s dwells, each phase bracketed by HUD-clock screenshots:

  min speed (LT)  1 856.9 deg / 8.01 s wall, clock x1.247 -> 185.9 deg/game-s
                  vs AV_Roll_Min 200
  max speed (RT)  1 181.2 deg / 8.02 s wall, clock x1.218 -> 120.9 deg/game-s
                  vs AV_Roll_Max 125

So roll behaves exactly like pitch: the rate cap falls as speed rises and
_Min/_Max mean "at minimum / at maximum speed". The withdrawn claim that roll
shows NO speed dependence is reversed, and the axis rule is now confirmed on a
second axis instead of contradicted by it.

Both land just under their caps (93% and 97%), the right side for a rate limit.
The shortfall is NOT explained and no claim is made about it: candidates are the
craft not being exactly at min/max speed after 5 s, and the 20 Hz swept-angle sum
undercounting.

The tell that the old result was broken was two conditions agreeing too well. The
tell that this one is sound is that they disagree in the direction the definitions
predict, on two independently bracketed phases.
