experiment proposal: PSGD Kron baseline lane. I will implement a single-file PSGD Kron optimizer for the block matrix parameters, keeping the existing AdamW auxiliary groups unchanged and preserving dataset, architecture, batch size, and one forward-backward pass per step. Starting point from README: lr=0.0005, weight_decay=0.625. First run will target a conservative 5750-step check to see whether it can reach 3.28 at all; if early curve is pathological, I will stop and report the negative result. This avoids the active AdamW and Muon/Muon² lanes.
