Serves jcbtc/Qwen3.8-27B-IU4-Kairic-Edge (four-artifact payload) with
the qualified pinned-runner profile: 262K ctx, 1 slot, b2048/ub512,
t16/tb32, f16 KV, 32 ctx checkpoints, 8 GiB prompt cache with idle-slot
persistence, native MTP4, deterministic sampler, reasoning off.
The serve script replicates the release pinned runner verbatim; the only
differences are safe bind vars (no bare HOST env var; HIP collision rule)
and this machine's split 7.15 SDK LD_LIBRARY_PATH layout.
Rollback: revert this commit and redeploy; v3 model files and the v3
binary are untouched.
