The base qwen3.6-35-a3b is already ttl: 0 via the `pinned` group. The three other Qwen 3.6 variants (abliterated, heretic, 27b) had ttl: 600 → llama-swap auto-unloaded them after 10 min idle, costing the next request a full reload (~5-15s). Removed so they stay loaded once warm. Still get evicted by the normal swap when another non-pinned model is requested — these aren't joining the pinned group, just losing their idle-unload timer.
