What was computed

Stored plasma energy W_p = 10.15 GJ — 3/2·V·(n_i·T_i + n_e·T_e), V = 1022.35 m³ (solve_mirror), n_i 2.0e20 / T_i 90 keV, n_e 2.6e20 / T_e 89

Reproduce this

# Reproduce ENV-A3-BU against the frozen record
pip install kronos-toolkit   # github.com/KronosFE/kronos-toolkit
python -c "from kronos_toolkit.verify import run_regression; run_regression()"
# ENV-A3-BU is anchored in the 2026-08-27 freeze spine (verdict: reproduced).
