  "scope": "Historical BF16 control, fixed 4096x4096 text-to-image, no references, six steps. Four GB300 GPUs; DiT TP1, Ulysses SP4, ring1, encoder TP4. Separate from the MXFP8 API and 160-request serving datasets.",
  "execution": "Both paths distribute tiles across four GPUs. Native eager executes per-rank tiles sequentially; optimized decoder uses CUDA Graph replay and six streams per GPU. The difference measures the combined execution path.",
  "aggregation": "HTTP values are medians of the selected lifecycle medians (five measured requests each after warmup). VAE timings are median rank-0 stage measurements over the available control cycles; they are not summed with separately computed HTTP medians.",
