On gfx1151 with the same DeepSeek-V4-Flash-0731 UD-IQ3_XXS artifact and f16 KV, the carried Strix Halo Vulkan fork at baf6360be passed the house 4-item guard and completed every bounded llama-bench cell through d262144 without a device loss. Mean prefill/decode was 219.36/19.54 t/s at d0, 181.55/17.83 at d32768, 142.56/15.41 at d131072, 126.50/14.24 at d204800 and 115.04/13.32 at d262144. This directly supersedes the stock-build-only conclusion in clm-0059 that Vulkan could not survive beyond d0, but it does not prove Vulkan generally safe: the fork bundles multiple kernel, prefill, DeepSeek and newer-upstream changes, and only a binary guard—not the full capability suite—ran on this configuration.

METHOD -- Nathanw1014/strix-halo-llamacpp portable Vulkan payload baf6360be (build 10565), staged with its pinned Mesa 26.3.0-devel RADV driver and documented GGML_VK tuning environment. Same 97 GiB DeepSeek artifact as the earlier stock matrix; f16 K/V, flash attention, --load-mode none, pp1024, tg256, batch 2048, ubatch 512 and 16 threads. N=3 fresh processes at d0/d32768/d131072; N=1 at d204800/d262144. All artifact rows report rc=0 and build baf6360be. Throughput windows carry wall-meter Wh totals in eng-0179 through eng-0183, never Wh per correct answer.
