getAutoWeight

Auto (reliability) weighting. When true (default), the text/image split is derived PER DOCUMENT from each branch's decisiveness (the top1−top2 margin of its per-label scores) — the more confident branch on that document is trusted more — and / are ignored. When false, the fixed / ratio is used. In BOTH modes a weight of 0 still fully disables that branch (skipping its extraction/rendering). The effective per-document image weight is reported on the result for transparency.
