2026-09-25: MLA paged decode for DeepSeek-V4-Flash over an FP8 cache (kernel mla_paged_decode_fp8), with scalar dequant scales k_scale / v_scale and cache_stride in bytes. sinks (per-head attention sinks, FP32) may be null. The compressed-KV pool is attended only when comp_pool is non-null and comp_block_count > 0.
