Voice-agent router, GGUF: Granite 4.0 H 350M + LoRA (kd-web4-s0), Q4_K_M

The production router of the AI-231-ME3 voice agent as a ready-to-serve GGUF, so that nobody has to merge the adapter and convert it. It is the LoRA adapter martinnavs/granite-4.0-h-350m-router-kd-web4-s0 merged into ibm-granite/granite-4.0-h-350m and quantised to Q4_K_M. Read that model card first: it says what the router does, how it was trained and tested, and where it is wrong. This is an adapter-derived router, not a general assistant: it writes one tool-call line per request (NAME|arg|arg) or escalate|<reason>, only works with the exact system message and grammar the voice agent sends, and behaves unpredictably outside that setup.

Licence: Apache 2.0, as the Granite base model; the quantisation changes nothing about the terms.
