Fresh flight, row pinning CONFIDENT (margin 0.413), one sweep and nothing before
it. axis_probe now REFUSES to measure on a WEAK pin (ALLOW_WEAK_PIN=1 overrides)
since it is a precondition, not a warning: roll is immune to the up/right
labelling but pitch and yaw are not.
Clock x1.26. Binned by speed, both in game units, against the linear
interpolation of AV_PitchPlus_Min 150 (at MinimumVelocity 100) to _Max 70 (at
MaximumVelocity 1200):
speed ~435 measured 100.8 predicted 125.6
speed ~572 113.8 115.7
speed ~709 126.3 105.7
speed ~846 83.1 95.7
speed ~983 72.7 85.8
Supported: the magnitudes (73-126 measured vs 86-126 predicted) and a falling
high-speed end. NOT supported: the interpolation law. Scatter is +-25%, the two
fastest bins hold 1 and 2 windows (the first moments before the speed bled), and
the slowest bin misses in the wrong direction.
The flaw is structural, not statistical: a sweep DRIVEN by the speed bleeding
cannot dwell at either extreme, which is exactly where the law is most testable.
What would settle it: hold a settled throttle and pitch for ~1 SECOND, so speed
barely moves inside the burst and each burst gives one honest (speed, rate) point;
repeat at LT / neutral / RT for three clean points at known speeds. Recorded as
the next design rather than attempted as a fifth variation of the same sweep.
Both fixes the previous run's caveats asked for, plus one the run itself forced.
axis_probe.py now:
- PINS which non-forward row is up and which is right, by comparing world-Y
across the rows in level flight, and says CONFIDENT or WEAK. entities2
measures row 2 = forward against velocity, but the other two were labelled by
the D3D convention, and yaw/pitch SWAP if that is wrong -- so the previous
run's last two columns were named on an assumption.
- checks the craft is ALIVE between inputs, and ABORTS with a message instead of
reporting the clean zeros a destroyed craft produces. The first run ended on
GAME OVER and only said so afterwards.
- measures the UNKNOWN inputs (rx, ry, LB, RB) first while the craft is healthy,
keeping the established lx/ly as controls at the end.
fly_stage.sh now WAITS for the stage load instead of sleeping a fixed guess. The
fixed sleeps worked until they didn't: one load ran long, the script pressed START
into a black screen, and every later step went to nothing while the screenshots
recorded a plausible-looking sequence. It now polls for a non-black frame and
aborts with a pointer to the log if the load hangs (PhysicalHeap::Release
failures) rather than continuing blind.
The probe itself did not run this iteration -- the stage load hung -- so there is
no new axis data, and none is claimed.
New probe (axis_probe.py) decomposes every held input into all THREE rotation
components at once, instead of measuring one axis at a time through a non-forward
matrix row -- the flaw that once made roll and pitch produce identical numbers.
For previous rows (f,u,w): roll = atan2(u.w_old, u.u_old), and forward's rotation
toward each of the other two rows gives the remaining pair.
Stage 02, file pad, full deflection on exactly one channel at a time:
lx+ roll 209.8 b 0.9 c 10.1 deg/wall-s
ly+ roll 0.0 b 154.1 c 0.0
rx+ roll 0.0 b 0.0 c 0.0
ry+ roll 161.1 b 87.0 c 37.1
LB/RB all zero
What this supports: lx = ROLL, cleanly (~0 on both other channels), agreeing with
the independent roll measurement. ly drives ONE axis, cleanly.
What it does NOT support, and I am not claiming:
- WHICH axis ly drives. entities2 measures row 2 = forward against velocity, but
rows 0 and 1 are labelled up/right by the D3D convention rather than by
evidence, and yaw/pitch SWAP if that is wrong. Roll is immune (rotation of
either non-forward row in their shared plane is roll either way).
- anything about rx/ry/LB/RB. The run ended on GAME OVER: full-deflection spin in
a live combat mission gets the craft destroyed, and the only symptom is "0
player candidates" AFTERWARDS, so late rows may be post-death. rx+ reading all
zeros and ry+ reading mixed are exactly what a dying craft would produce.
So "yaw: no input found" is NOT resolved. Both gaps are now written into the
probe's header with what would fix them: a liveness check between inputs, and
pinning up-vs-right against world Y.
