- 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.
The processor appended sweeps the GUI fed back to its own history, so its next replay
published them twice and out of order, and the B-scan came out with rotated columns.
Fed-back sweeps now stay out of that history, results are kept in timestamp order,
picking the displayed combo only redraws and only new sweeps are recorded to disk.
The sar3d processor is rewritten as a checked port of Multi_antenna_3D_clean_v1.ipynb:
NVRTC kernels, timing from the trace stamps, notebook parameter names and one cubic
SAR_VOXEL_M. It adds front, side, top and 3D views, drops gpr_cpp and the parity tools,
and the GUI speed now applies only while the socket speed is ignored.
The grid bounds are now explicit config (sar3d_x/y/z_min/max_m) instead of
being derived from the antenna span and the depth gate. The depth mask
still zeroes voxels outside [min_depth, max_depth], so the wider Z window
just shows the masked wedge. The bound fields are double: the parity tool
recomputes the notebook-derived bounds (notebook_grid_bounds) and passes
them through the live config, and a float roundtrip shifted the axes by
~1e-7 m, flipping depth-mask knife-edge voxels against the reference npz.
Parity on frames 0034-0036 unchanged (1.3e-6, axes bit-match).

- replay_raw_producer carries the RECORDED per-trace capture windows
from each snapshot's meta.json (re-anchored by the same shift as the
frame time) instead of one synthetic window for all traces — without
this the segmented timing model degenerates in replay;
- GUI/profile/orchestration swap the removed window knobs
(center_depth, half_width_*, grid_n*) for the notebook parameters
(ground depth, pitch override, voxel pitch, Y range, X margin, norm
edge margin, smooth sigma, comp power, tx per segment).
Headless replay smoke on the 20260922_mine_fast_true dataset passes:
51 sar3d result collections, transparent preprocessor.

The display threshold from 'add treshhold' (e113ef6) was meant for the
sar3d projections; the GPR heatmap goes back to full-range levels and
the constant moves into sar3d_plot_mixin.

MultiDeviceLibreVnaService only exposes the 2x4 virtual combo matrix on
its own USB transport. When a physical GPIO switch sits on the master
stimulus and/or slave receiver path, the effective matrix is wider than
that. SwitchedMatrixRadarService wraps the inner service and drives the
extra switch(es) between acquire_collection calls, widening the combo
matrix by the physical position counts (matrix_output_switch_positions /
matrix_input_switch_positions in RunConfigModel).
Combo-matrix construction was centralized into
RunConfigModel.build_runtime_combos() so the GUI, workflows, and codec
all derive the same widened matrix instead of each computing its own
version of the virtual 2x4 layout.
