BR-L2-A27reproducedverification card freeze 2026-08-27

What was computed

RustBCA COMPLETE (36 cases): D/T/He on W + Ta32Re26W18Ti14V10. Peak yields: alloy 1.44e-01 vs W 8.92e-02 atoms/ion (alloy light-species Ti/V dominate; heavy W/Ta/Re below threshold <=300eV). Erosion sub-monolayer/pulse at DP flux; physical sputtering only

Reproduce this

# Reproduce BR-L2-A27 against the frozen record
pip install kronos-toolkit   # github.com/KronosFE/kronos-toolkit
python -c "from kronos_toolkit.verify import run_regression; run_regression()"
# BR-L2-A27 is anchored in the 2026-08-27 freeze spine (verdict: reproduced).
