| # 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. | |
