# Seam: the frank-medium quadlet on dankserver.
# frank-medium became a rootless Quadlet container on 2026-09-15 when the
# vllm-radiance MXFP4 stack replaced the charlie12345/ROCmFPX llama.cpp
# runtime on the 2x Radeon AI PRO R9700. This seam pins the properties that
# make it work and that no reviewer can see by reading the flags alone: GPU
# device access on the fixed device indices, the upstream launcher's podman
# posture, host networking with the fleet's client port and alias, the
# measured KV pin for this exact hardware signature, boot persistence, and a
# deploy handler that retires the old root unit without deleting anything.
