  "note": "Eager exchanges up to 128 tokens are host-launch bound (55-62 us) and one process per arm was a 50-100 us outlier; per-repeat medians favored Masked by 4-5 us at 1-8 tokens in two of three repeats. A separate profiled eager trace (T=1, H2048) showed the role path with fewer host CUDA API calls per exchange (19 vs 20), less API time (16.5-20.0 vs 18.8-23.2 us) and a shorter Attention period (78-79 vs 84-89 us), so the small-token eager difference is host/process jitter, not role-path host work. From 512 tokens the role path is faster in every repeat."
