What was computed
NV-diamond quench precursor: delta-B 0.189 pT/rtHz, bandwidth 125 kHz; quench step ~100 mT at 2mm standoff -> per-shot SNR ~1.5e9, single 4us-shot detection (lead time set by NZPV ~ms >> us latency)
Reproduce this
# Reproduce KX-L1-A22 against the frozen record pip install kronos-toolkit # github.com/KronosFE/kronos-toolkit python -c "from kronos_toolkit.verify import run_regression; run_regression()" # KX-L1-A22 is anchored in the 2026-08-27 freeze spine (verdict: reproduced).
