Ruby port of Laya: typed decisions (choice, score, noul) over any state in a single forward pass, with calibrated probabilities and a router that picks the right checkpoint per request (English, multilingual, typed-decisions). Inference runs on ONNX Runtime against exports of the published checkpoints, so installing needs no Python, no LibTorch and no compiler. Language and script detection, email cleaning, workflow presets and the embedding shortlist are pure Ruby.
