Prevents memorization of fixed simulation parameters that exist only in training. Each epoch randomizes: - tx_cost_multiplier: U[0.5, 2.5] (was fixed 1.0) - spread: U[0.5x, 3.0x] base spread - fill_ioc_prob: U[0.65, 0.95] (was fixed 0.85) - fill_limit_min/max: randomized ranges - spread_cost: U[0.3, 0.8] fraction - Episode starts: ±25% stride jitter (was deterministic) - Episode length: ±25% base (was fixed) Controlled by enable_domain_randomization flag (default: true).
