- BG_GATE_ENABLE: frame peak over its median background (sar3d_background); the GUI scales the frame with bg_gate_gain and its cloud threshold. - SAR_CLEAN_ENABLE: CLEAN of a one-frame aperture on a 4x10x4 cm search grid over the whole scene; objects in their own scale (sar3d_objects). - SAR_MARK_ENABLE: boxes by class around object groups (sar3d_marks), with the legend under the views. - SAR_VOXEL_M as three steps X/Y/Z with the notebook defaults 0.025/0.02/0.02. - GPU backend: image/download/load/project API, per-plane block reduction for the maximum, depth gate without FMA; sar3d host code built with -ffp-contract=off. - References regenerated from notebook cells 1 and 5, with new CLEAN scenes and a synthetic box-rule case; docs updated.
