micro-kiki Router v4 — 34-Domain Multi-Label Classifier

MiniLM-L6 embedding + MLP head. Classifies a user prompt into up to 34 domains (sigmoid, not softmax — domains are not mutually exclusive). Used at inference time by the micro-kiki serving layer to pick the top-K LoRA adapters to load alongside the Qwen3.6-35B-A3B base.
