Treasury goes past budget-versus-spend to the question finance actually asks: what did each dollar buy, and for whom. Unit economics allocates your AI spend & shipped outcomes across project, model, agent kind, and any tags you stamp on events (for example customer or feature), with cost per merged PR on each dimension. Spend only lands where the data carries the dimension, never smeared, so the split is honest. Stamp events with tags and cost per customer or per feature becomes a dimension here.
