Ran the full FTPO fine-tune to completion: 4h12m wall-clock, early-stopped at
step 380/750 by the configured chosen_win=0.85 threshold, train_loss 4.0->2.19.
Output is a merged 16-bit model plus LoRA adapter.
Also fixes an UnboundLocalError in core/orchestration.py when resuming a run
with generation disabled (--generation-step-enabled false), which is needed to
re-run just the finetune stage against an already-generated dataset.
Documents an unrelated platform incident: an uncapped multi-hour finetune
triggered a thermal shutdown mid-run with no checkpoint saved, requiring a
restart from step 0. Capping GPU clocks/power before the retry let it complete
without issue.
