Whether an IOU port can terminate on a persistent TAP (iol_bridge add_nio_tap) is a capability of its own: the tap module and that command land independently, so a build may have one without the other. Probed on a scratch IOL bridge with a scratch TAP — one add/delete cycle, no iol_bridge start needed (attaching a NIO works on a stopped bridge) — cached by binary identity, with the scratch bridge id above the per-node id space the fabric locks (513..1024) so a probe cannot collide with a running node. Any failure, including an old build's "Unknown command", means unknown: IOU stays on the relay datapath. Reported through /capabilities as ubridge_iol_tap, next to ubridge_tap.
