results-report: Muon LR/WD schedule one-off was stopped early. Setup: train_steps=3400, Muon lr=0.027, wd=0.014, LR cooldown_frac=0.55, WD warmup over first 15%. Result: step 1500 val_loss=3.53211, behind 3500-step Muon baseline at same step (3.50272), so I terminated at step 1535 and will not expand this lane. Artifact: artifacts/muon_wdsched_cmpatino-1/. Takeaway: higher LR/WD plus delayed cooldown and WD warmup was worse mid-training.
