# Seam: the frank-large ik_llama.cpp root unit on dankclaw.
# ik_llama.cpp replaced the halogen rootless Quadlet on 2026-09-15. This seam
# pins the deployment-policy properties that no reviewer can see by reading
# the flags alone: a root unit whose files all live in this repo, the hybrid
# placement contract (experts + PLE mmap'd on the CPU path — NEVER the
# CUDA_Host pinned buffer), no pinned CUDA host memory, the single client
# port every consumer already targets, the fleet alias, greedy-by-default
# sampling, vision via the mtmd mmproj, and a deploy handler that retires
# the halogen quadlet without deleting it.
