Measured, not argued: command a 45-degree-off-the-nose error and watch whether it
shrinks, both axes, both sides, two pulse widths, with the opposite sign as a
control. Yaw's sign is correct (45 -> 11.3/32.7 at 0.6 s, 41.6/33.8 at 1.2 s).
Pitch's is inverted - the pilot's own sign GREW the error every time
(48.3/55.6/70.7/91.7) and the opposite shrank it every time (30.7/41.5/15.7/9.6).
A method artefact is recorded because it gave the opposite answer first: a 3 s
full-deflection pulse overshoots a 45-degree error so far that BOTH signs look
wrong (45 -> 164 and 45 -> 178). A long pulse cannot answer a sign question.
Verified against the game rather than by inspection. Before: fire=1 in 0 of 13521
samples, |aim yaw| pinned at 90.0, target 36-43 km away. After: 43 of 1732, aim
down to 2.3 degrees, range median 6.3 km, and the HUD's own ammunition counters
moving - NOSE BM 06000 -> 05723, MAIN MPM 00300 -> 00298.
Also fixed a leftover of the same FIFO era: pilot.py called pad.f.write("tap A
90") for the target-select double tap, which raised AttributeError once Pad
stopped having an `f`. Pad gained tap()/dpad(); ctrl_probe.py and target_probe.py
still use pad.f and now say so in place.
Still open: YOU KILLED is 0000 after 250 s of firing and REMAINING OB is still
012. The craft shoots, closes and selects; whether it destroys anything is next.
