BU-L1-A2reproduced● reduced-order (live-capable) freeze 2026-08-27

What was computed

p_mag 115/279/358 MPa @17/26.49/30T; Lame t_req 0.16/0.48/0.71 m vs 667 MPa allow; FEA 0.66x = stress ratio PASS, consistent

Reproduce this

# Reproduce BU-L1-A2 against the frozen record
pip install kronos-toolkit   # github.com/KronosFE/kronos-toolkit
python -c "from kronos_toolkit.verify import run_regression; run_regression()"
# BU-L1-A2 is anchored in the 2026-08-27 freeze spine (verdict: reproduced).
