-description: "The RETIRED frank-large runbook (2026-09-28 → 2026-10-01, rollback target via tag frank-large-gufo-q4kxl-20261001) — gufo (gufo-org/gufo) v0.1.1, the Strix Halo inference engine, built from source on Dankclaw and serving the abliterated ajgazin/Swift-1.5-Qwen3.8-27B-Uncensored UD-Q8_K_XL with the z-lab DFlash2 Q4_K_M drafter on the gfx1151 iGPU: the from-source build and its two host workarounds, the GGUF header evidence that made the payload swap safe, the one-session / full-window shape, why the fleet's Qwen-Sharp chat template CANNOT be used on this runtime and what that costs, the client-contract delta, the measured prefill/decode trade, and the failure modes worth knowing."

-> **RETIRED 2026-10-01** — replaced by [[frank-large-vllm-mimo-v26-bf16]]
-> (vLLM TheRock + MiMo-V2.6 BF16). Rollback: git tag
-> `frank-large-gufo-q4kxl-20261001`; the gufo build (`build-gufo.sh`), the
-> Q4_K_XL payload and the DFlash2 drafter all remain on the host.

+> 6.19-9.01 t/s; every ≥6-bit vLLM quant path dead on gfx1151). The shape

+> UD-Q4_K_XL** (16.35 GiB, vanilla — the abliterated Swift Q8 was
