# Kaggle kernel body for P4 probe 2, the soak (2x T4, ~1.2 h). Same pinned body as the smoke, one
# environment difference: MODE=soak, which runs 180 steps at the real step shape without gradient
# checkpointing, through three push/verify/prune cycles, a forced cold resume and the horizon's
# validation pass -- and gates on the memory of the leg that never evaluates. That gate is D-018.
