-Out-of-distribution eval needs no files at all -- those scenes are generated from seeds
-9000000-9000019 at run time, and both control rates draw the same ones.
+Out-of-distribution scenes ship here too, under `eval_scenes/ood_scenes_s20_250`. They are normally sampled
+from seeds 9000000-9000019 at run time, but that only reproduces on the machine that produced the
+published numbers: the sampler's bowl-clearance test reads mesh radii out of `assets/`, and the
+result also depends on the robosuite/MuJoCo build and the floating-point path. Replaying the frozen
+scenes removes all of that. The dumped scene names match the ones in the original eval logs, and
+replaying reproduces the seed-sampled scene exactly (object, bowl and joints identical; end-effector
+differs by 3e-08 because `init_*` is stored float32, a property of the original pipeline).
