PR #81's pool half measured inert the day it deployed: the 66,560 boot printed the same elastic 26.73 GiB / experts 20.72 / kv cache 5.64 / vram_weights 24.30 as the 49,152 boot and opened the pool with 0 B used, and the qwen38-w5nl64 rig moved vram_kv 269.99 -> 271.25 MiB (window still 7,436 tokens: its 95.37 GiB n-gram table claim decides, not the pool). The step half stays. Tests: 576 ok / 0 fail.
