Summary
Why
Mixed decode/prefill batches with tokens from different sequences regressed versus Triton because the C4A CuteDSL packed-layout kernel used too many lanes for too little per-lane work, and C128A used more warps than needed for the 128-row compression window. The new mapping increases per-lane vector work for C4A and reduces C128A reduction overhead.

No issue number was provided. I searched open PRs in
