Kernel eligibility becomes "both endpoints on one compute, each able to anchor": Docker always (adapters are born as veth pairs), QEMU when that compute's uBridge can create the persistent TAPs its adapters anchor on. The question is asked per compute, because the link needs both ends anchored -- so a mixed or half-upgraded deployment degrades to the relay instead of failing an attach. probe_tap_support() creates and deletes one throwaway persistent TAP through a scratch uBridge, cached by binary identity like the tc report; /capabilities exposes `ubridge_tap` (absent = unknown, which keeps links on the relay). The compute route for a QEMU adapter NIO took UDPNIO only, so a kernel link was rejected with 422: its body and response now accept Union[UDPNIO, BridgeNIO] exactly like Docker's. Stale "Docker-to-Docker" wording in the config, link and MCP descriptions now talks about anchors, and docs/features/qemu-kernel-datapath.md documents the datapath -- verified end-to-end on a real instance: 32/32 kernel-datapath checks and 29/29 on the relay variant.
