   "Right*", W1/W2 = "Front*" -- with theta = atan2(z,x) from +X toward +Z, the
   mech-local FRONT is the **+Z arc (theta 45-135 deg)** and dead-ahead is the

+  **1995 resolver frame**.  OUR engine's entity frame carries forward along
+  **−Z** (bench-measured: a victim facing its attacker took frontal beams at
+  local z=−4..−10, θ≈270°, resolving the REAR-named cells — which was the whole
+  night-10 field table: rear panels unhittable, Owens flanks CROSSED).  The
+  frames differ by a **π rotation about Y** (rotation, not reflection — the
+  flank observations cross rather than persist), so `ResolveHit` negates
+  local x and z after `WorldToLocal` before the band/wedge math.  A/B verified:
+  frontal fire θ≈1.5 → utorso/dtorso/ltorso/rtorso, zero rear zones.  The
+  separate "one band LOW" Y-signature is #16 (pick-ray parallax), not this.
   Frontal unaimed foot-band hits therefore straddle the RightFoot/LeftFoot
   cells by impact-x sign, and the authored cross-bleed (20% opposite foot,
   10+10% opposite leg) is a data-true source of "hit the opposite leg" reports.
