Boresight parallax FIXED + the #4/#5 verdict instrumentation (Gitea #16, #4, #5)

Browse Source 
PARALLAX (#16): the pick/fire ray was anchored at mech.y+5.0 (a port
improvisation) while the sight line ran from the eyepoint (y=6.23) --
two parallel rays whose constant offset grew into the reported low-miss
as range closed (measured ry +0.072 @50u -> +1.54 @2.7u).  The decomp's
sight and pick share the eye origin (HudSimulation @4b7830 chain).  Fix:
the viewpoint mech's cockpit eye owns the aim-camera publish in BOTH
views, origin = its own eye translation; leveling + deliberate elevation
untouched; chase view now converges to cockpit ballistics (V cannot
change where shots land).  After: pick pinned to the crosshair (ry <=
5e-6) from 50u to point-blank; 26 laser + 8 missile center-mass hits at
3/4-screen.  Awaiting the reporters' approach-test.

VERDICT INSTRUMENTATION (#4 closed authentic, #5 verdict posted):
BT_RANGE_LOG per-frame pick tracing + BTGroundRayHitExact analytic
cross-check (0/8000 arena fall-throughs; cavern 6/8400 single-frame
grazes -- the 'crazy sliding' is the authentic world-pick + 500 m/s
slide over depth discontinuities); BT_AUD_TAIL StopNote/fade timing +
BT_FIRE_PULSE single-shot driver (the energy 'buzz' is the AUTHORED
charging loop: crescendo through recharge, 1.309s authored release,
measured within one frame).  CAVERN.EGG: solo cavern test egg.
