How Grok is used

Training never sees Grok. At forecast time the official line is the hierarchical ensemble. The Week slider is a labelled scenario: it linearly mixes Grok’s own home/away corner line with NearPost, up to a 50/50 split. Grok is asked for sharp match facts (full-backs, set-piece takers, XI shape, referee, weather) that actually move a corner line. Unibet stays a comparator.
