Cap score chunks by the existing page bound without discarding useful parallelism. Bound partial top-k chunks by twice the padded selection width so short contexts avoid excessive partial results and merge work. Keep the existing occupancy targets and graph-safe shape inputs. Extend decode correctness coverage to 9- and 65-page bounds, including padded and speculative query layouts. This is a measured follow-up to the owner grid policy in PR vllm-project#49229; its author's branch is unchanged.

Purpose
Cherry-pick public vLLM commit
8b00f41to retune the MiniMax-M3 decode indexer launch grids:TARGET_GRID: 512 → 4096TOPK_TARGET_GRID: 64 → 512While testing MiniMax-M3 on B300-agg with TP4 at concurrency 24 using a large agentic benchmark client, I observed total throughput improve from 26.5K to 38.2K TPS/GPU (+44%) and mean ITL improve from 38.2 ms to 26.0 ms (-32%). The larger grids expose more parallel work for the decode indexer on high-SM-count GPUs.
