Strix Halo running qwen3.6-35B-A3B was hitting 94°C with 2 concurrent
slots, causing 300s request timeouts. Mumuni + Koby accumulated 15
timeouts in the last hour. Reduced to 1 slot for thermal headroom.
Medium and Default tiers already route VLM before MoE as fallback,
minimizing overflow traffic to the hot GPU.
