# Kaggle kernel body for the Phase 4 stop/resume probe (2x T4). `save_notebook` cannot pass arguments, so
# this wrapper pins the probe's revision and sha256, sets the one thing that varies between submissions
# (MODE), and hands over. Edit REV/SHA/MODE before submitting; the probe asserts its own file hashes and
# refuses an unknown MODE, so a stale paste here fails fast rather than running the wrong experiment.
