Editing a rule immediately updates its replay.
Interestingness metric
After burn-in, deterministic sample cells are recorded through time. The score rewards hard-to-compress Lempel–Ziv histories, changing cells, balanced density, and low short-lag autocorrelation. Exact repeated global states receive a severe penalty.
