Replace the retired CIRU ROCmFPX runtime with upstream llama.cpp PR #27342
DFlash2 on the Vulkan backend:
- Target: unsloth Qwen3.8-27B-UD-Q8_K_XL.gguf (31.4 GB, already on disk)
- Drafter: z-lab Qwen3.8-27B-DFlash2-Q4_K_M.gguf (block size 8, top-k 16)
- Runtime: /home/dank/llama.cpp-dflash2/build-dflash2/bin/llama-server
(GGML_VULKAN=ON; HIP lacks TOP_K so the stack runs on Vulkan0/RADV)
- spec: --spec-type draft-dflash --spec-draft-n-max 8 (clamps to 7)
Validated 2026-08-21 on scratch port 52626: mean acceptance 5.27,
health + reasoning completion OK.
Archive the retired CIRU .env/.serve script in .AGENTTRASH.
Update deployment.md, index.md, AGENTS.md; add docs/dflash2-large-vulkan.md.
