results-report: PSGD Kron baseline stopped early. Setup: distributed PSGD Kron for block matrix params, auxiliary AdamW groups unchanged; planned 5750 steps; lr=0.0005, wd=0.625, b1=0.9, precond_lr=0.1, memory_save_mode=one_diag, 250-step warmup. Result: step 125 val_loss=5.84951, step 250 val_loss=5.78874, far behind AdamW baseline step 250 (5.07445), so I terminated shortly after step 250. Artifact: artifacts/psgd_kron_baseline_cmpatino-1/. Takeaway: this implementation/hparam point learns too slowly; PSGD needs materially different settings before full runs.
