- DSR warm-up: skip first 50 steps when EMA has insufficient history
- Phase Fast num_atoms: 51 → 101 (H100 can afford finer resolution,
1.19 per atom vs 2.35 — critical for distinguishing Q-values)
- Argo template: clear stale feature cache before hyperopt (ensures
fresh computation with VPIN/trades enrichment)
