# Seam: the frank-medium service on dankserver.
# frank-medium became a rootless Quadlet deployment on 2026-09-15 when the
# vllm-radiance MXFP4 stack replaced the charlie12345/ROCmFPX llama.cpp
# runtime on the 2x Radeon AI PRO R9700. The intended shape is one
# tensor-parallel process across both cards (frank-medium.container, kept as
# the target); it cannot run on this host because RCCL's kernels require PCIe
# atomics and the second card's chipset path advertises AtomicOpsCap: Routing-.
# The deployed shape is therefore two single-GPU replicas behind a round-robin
# proxy, which keeps the fleet contract of one :7770 endpoint. This seam pins
# the properties that make that work: GPU access on the fixed device indices,
# the upstream launcher's podman posture, host networking with the fleet's
# client port and alias, per-replica resource shape, boot persistence, and a
# deploy handler that moves the unusable TP=2 unit into the trash.
