There was a problem hiding this comment.
this is a noop test in terms of determinism.
Records 64 copperlists twice, resims the stream, then resims again from a mid-stream keyframe. Counters on base/refine pin that the quanta really run; the old call path leaves them at zero.

Adds a non-regression test proving the anytime runner (#1232) did not break deterministic replay.
An anytime node compiles to a base step plus
max_refinesrefine steps, and each of those steps reads the clock, stamps status text and (for the base step) freezes the task. That is a lot of new emitted code around the parts replaydepends on, and nothing covered it so far.
core/cu29_runtime/tests/replay_anytime.rsbuilds a small sim app —src -> planner -> smoother -> sink— whereplanneris a scored anytime node (max_age_ms+quality_target+max_refines) andsmootheris aquality-less one (
max_refinesonly), so the test covers the DOA age check, the per-quantum clock reads, an early quality stop, and a stop by plan position.
