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.

# Serve unsloth/Qwen3.8-27B-UD-Q8_K_XL as frank-default-large with a
|
|
# z-lab DFlash2 drafter (Qwen3.8-27B-DFlash2-Q4_K_M) on the Vulkan backend.

|
|
# Runtime: upstream llama.cpp PR #27342 (DFlash2 support) built with
|
|
# GGML_VULKAN=ON for the Strix Halo gfx1151 (RADV). DFlash2 selects its
|
|
# candidates through TOP_K + ARGMAX ops that the HIP backend does not
|
|
# implement, so the whole stack runs on Vulkan0.
|
|
#
|
|
# The target and the drafter share the Qwen3.8 arch. DFlash is lossless
|
|
# under strict rejection sampling. --spec-draft-n-max clamps to the drafter's
|
|
# trained block size (8).
|
|
#
|
|
# Tunables come from frank-default-large.env in this directory unless
|
|
# FRANK_LARGE_ENV_FILE overrides that path.
