- §1 Introduction rewritten with AHBM-first opening, in-paper KernBench platform overview, GQA motivation and three architectural requirements, three matching HW-SW co-design mechanisms (GQA-aware placement, PE_IPCQ, composite-command GEMM under PE_SCHEDULER), broader- applicability outlook (PE_IPCQ as collective substrate, composite command for fused operator pipelines), and outline. Consistent with the Executive Summary structure. - Executive Summary: extended broader-applicability closing with a forward-looking line previewing FFN/MoE integration. - §5 section heading renamed from "All-Reduce Acceleration via PE_IPCQ" to "PE_IPCQ and Collective Communication". - Title page date line refined to "2026 H1 Report".
