Live anonymous probes (2026-09-13, HermesAgent UA, 4 rounds): nemotron-3.5-lightning-free
returned zero bytes for >90s on every attempt and nemotron-3-ultra-free took ~40s, while
mimo-v2.5-free answered 200 in 2-4s each time. An aux model (titles, compression, memory)
that hangs is worse than a delisted one, so the default moves to the model that works.
