Frozen result

What was computed

GPU fleet: DCLC gamma=0 warm-fill threshold 5.9% (~6.25%=1/16); marginal, not a margin

Reproduce this

# Reproduce BU-L2-A5 against the frozen record
pip install kronos-toolkit   # github.com/KronosFE/kronos-toolkit
python -c "from kronos_toolkit.verify import run_regression; run_regression()"
