Inspect source, license, environment and execution evidence before preparing. Preparation and execution are separate actions.

Success condition

StackCube-v1 env info.success is true after the upstream solver finishes, truncated is false, and 0 < elapsed_steps < max_episode_steps=1000; only then status is task_complete and exit is 0. The 1000-step motion-planning horizon is a Hub recipe condition, not the upstream default benchmark horizon.

Recorded evidence

not_run: Inspected the pinned solver signature, task registration, source license and wrapper contract. No simulator invocation evidence is attached. Version 1.1.0 explicitly sets a Hub 1000-step horizon and rejects truncated results; this updated wrapper has not been run in a simulator.
