Live recompute — run the engine

Move the inputs and the published kronos_toolkit re-derives the reduced-order 0-D breeder balance right here in your browser — WebAssembly Python, nothing leaves this tab. At the frozen defaults it reproduces the config-22021 anchor (Q 3.0763, 2026-08-27 canon).

Reproduce this

# Reproduce BR-L1-A4 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-L1-A4 is anchored in the 2026-08-27 freeze spine (verdict: reproduced).
