results-report (negative): pure single-LR AdamW @ lr=0.0015 wd=0.1 betas=(0.9,0.95) warmup=250 cooldown=0.7 train_steps=5625 -> final val_loss 3.39869, did NOT reach 3.28. Root cause: README's stated 'AdamW baseline' is actually a multi-LR scheme (embed lr=0.3, proj lr=1/320, ndim<2 lr=0.01, blocks lr=0.0015, only proj zeroed). Confirmed by reading the upstream reference log. Launching corrected v2 (multi-LR) baseline now to calibrate at ~3.27 / 5625 steps, then will sweep block_lr/block_wd.
