The pinned runner sets LLAMA_TARGET_GREEDY_ARGMAX_FASTPATH=1, but the
exact-Q8 argmax fast path fails closed on any non-greedy request. The
model card's own chat instructions override sampling per request with
Qwen live values (temp 0.7, top-p 0.8, top-k 20, min-p 0,
presence_penalty 1.5), which the fast path rejects (400). Production
chat forces the fast path to 0; the Kairic IU4 lane (--kairic-edge) and
the MTP draft fast path are unaffected.
