results-report: Lion higher-LR/lower-WD follow-up stopped after step 1625. Setup: block Lion lr=0.0003, wd=0.05, betas=(0.9,0.99), 250-step warmup; auxiliary AdamW groups unchanged. Curve: step125=5.29735, step250=4.78100, step500=4.16087, step750=3.92795, step1000=3.80085, step1500=3.65748, step1625=3.63311. This improves over the prior Lion lr=0.0002/wd=0.1 run, but still trails AdamW after warmup. Artifact: artifacts/lion_hilr_cmpatino-1/. Takeaway: Lion may merit a small LR/schedule sweep, but these two points do not justify full runs.
