Case 2 exploration on goal set A (Sim2Sim)
Generated by report_explore.py from results/rom_A_explore/*.npz and results/chrono_A_explore/episodes.jsonl.
Goal set A: 50 ID (10-20 m) + 50 OOD (20-40 m) goals. Pools: all 16 (released 1-4 + 12 new) and the 12 new policies.
Kendall tau-b of the ROM mean-rank order with the Chrono mean-rank order; 95 % goal-bootstrap ranges (2000 replicates,
stratified by goal range, paired). Delta = tau(condition) - tau(nominal ROM). These numbers were used to choose
the TR design that was then fixed for the held-out evaluation on goal set B. They are optimistic for the chosen
condition (selection among all rows); the held-out evaluation tests the choice on new policies and goals.
Condition 'paper_tr' is the noise-only TR (action and powertrain noise).
Parameter units: sig_* = sd of additive noise on normalized throttle/steering per 0.1 s step; steer_rate = max change of normalized steering per 0.1 s step; delay and hold in 0.1 s steps; wheelbase in m; vmax in m/s; tau0 in N m; omega0 in rad/s; yaw0, g_rot in rad; obs_pos_sig in m; gx_scale = goal-radius factor. K = trials per goal.

Per policy, goal set A (exploration)
Mean rank among 16 policies (1 = best). Success = share of goals (ROM TR: share of goal-trials).
