Put GPU1's idle ~11 GB buffer to work on the two KV-bound models that gained live consumers from the worldtree migration (granite + the pooling models under-use their util, so growing them is wasted): - selene 0.13→0.17: KV 2.53→6.33 GiB, concurrency 1.27x→3.16x @32K (Domari judge) - qwen36 0.32→0.34: KV 7.73→9.63 GiB, concurrency 2.92x→3.64x @131K (arbo judge + worldtree actor/echo + gateway) GPU1 free now ~5.6 GB (safe floor for single-service recreates).
