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The old sar3d core was a port of the superseded Horns_3D notebook and
produced wrong volumes. The compute core now follows the reference
notebook exactly:
- segmented_interleaved frame timing rebuilt from per-trace capture
stamps (uniform tx_per_segment split as the no-stamps fallback), with
the coarse inter-segment dtau and the intra-sweep dtau applied as one
phase ramp before the IFFT;
- ground scene coordinates with the ground_depth_m lift (scene Y=0 is
the ground), full-region grid instead of a window around a center
depth, geo_ref compensation anchored on the ground plane, power 0.3;
- notebook finalization in C++: |acc/cnt|, depth mask, normalization
without the Y-edge planes, separable Gaussian over (Z, X), level;
- CUDA kernel computes geometry in double: float32 loses ~3e-4 of an
A-scan sample in tau and drifts ~1e-4 from the float64 reference.
Live-config keys follow: the center_depth/half_width/grid_n window knobs
are replaced by ground/voxel/y-range/margin/sigma/power/tx_per_segment.
Parity against the notebook npz exports (frames 0034-0036 of the
20260922_mine_fast_true dataset): max|diff| <= 1.6e-6 off the depth-mask
knife edge, identical argmax, level rel diff <= 7e-7. Verified via
make sar3d_parity --dump-dir + scripts/sar3d_volume_compare.py; the
executable spec lives in scripts/sar3d_reference_check.py (bit-tight
against the npz, including the animation shifted-grid arithmetic).

Verified on the bench that the modified master bitstream excites in every stage
and the RF switch routes: 16 traces per sweep, 62 dB between the two switch
positions of one master port, 9.9k measurements/s. Adds the built master image,
two run profiles, a verification script and librevna_protocol.md, and drops the
stale prototype driver copy that the firmware tree still carried.
Independent monitor + checker for CHANGE_CURRENT_LD1 variation, where the
board sweeps LD1 current autonomously while both laser temperatures must stay
on their static setpoints. Nothing previously verified that the setpoints were
actually reached, so a stale temperature silently corrupted measurements.
New package python_app/hardware_full/laser_control/monitoring/:
- session.py: LaserVariationSession snapshot (targets + tolerance frozen at start)
- readings_channel.py: JSONL append/tail channel for per-sweep readings
- monitor.py: LaserTemperatureMonitor polls the board once per sweep, publishes
- checker.py: LaserTemperatureChecker validates temp1/temp2 vs targets (0.03 C),
warns to console per laser with anti-spam state
CLI entry points scripts/laser_temp_monitor.py and scripts/laser_temp_checker.py
run as independent processes communicating via IPC files.
Also: add temp_tolerance_c to LaserVariationModeModel (schema + codec round-trip)
and write the session snapshot from apply_kamil_adc_laser_control's variation path
so the checker works with pipeline-started runs too.
Tests in tests/test_laser_temp_monitoring.py (17 cases); existing laser-control
protocol and config-codec suites remain green.
