The H3 run trains with a loop of our own (LoRA on the attention and feed-forward projections of the 50 blocks, per-block checkpoint, uniform noise levels, musubi-tuner's approach) while ComfyUI carries the batches. Every Log record is flushed to disk as it is said and reloaded on start; the run writes each stage and step to it. ComfyUI's own offloading toggle is ignored by the new loop. UNTESTED on the real weights. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MpnF7GwNGMbngU11wjym7P
