14 circling rotations, fusion held fixed → swaps only bearings · model removes the Σ/Δ squint bias & halves bearing scatter (σ 3.7°→2.3°) → 95% HDR cross-range 327→280 m, area 1.09→0.91 km² · range geometry-degenerate (297 m baseline, bearings 11–27°) → 5–6 km down-range ribbon for BOTH; shipped mesh vs grid peaks disagree 764 m
