Measured on the live 16k agent setup (A/B with runtime flags, greedy answers vs reference):
decode 3.49 -> 5.24 tok/s, first token 4.3 -> 3.3 s, 2.3k-token prompt 27.5 -> 20.6 s,
same answers. Dropped after measuring: route stats on the CPU, a Triton router GEMV,
pregate prefetch from disk (all within noise or slower).
The GEMV keeps one config instead of autotuning: Triton benchmarks with a 256 MiB buffer
that torch keeps cached, which left 8 MiB of VRAM and made lazy kernel loads fail
(hipErrorNoBinaryForGpu). prain also returns torch cached blocks after materializing and
whenever the driver has < 128 MiB free. quality.py score --greedy-only skips prompt logprobs,
which OOM the 16k config.
