EMA-consolidated research checkpoint archive.

NEO in-context scale-calibration Phase-1 finetunes (base + cam00/01/02/05/10). Verdict: crop-zoom aug alone fixes zoom ([email protected]); oracle calibration token HURTS (-7.4, monotone in z).

Each *.shards.stepNNNNNN/state.pt holds only the EMA payload (state['extra']['ema'], fp32, clean names) extracted from the original training checkpoint, fingerprint-verified against engine_meta.pt. Loadable directly by methods/lafm/vla_flow_ft.py:load_pretrain_trainables with init_use_ema=true. Optimizer states were not retained.
