What was computed
CGYRO-linear UNLOCKED (link fixed, reg01 byte-matches ref: gamma +0.3179) — native GK spectrum can replace TGLF-fidelity at freeze
Reproduce this
# Reproduce BR-L2-A18 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-A18 is anchored in the 2026-08-27 freeze spine (verdict: reproduced).
