Andrei's builder treats transfer-of-registration and first-registration as cousins, not as two products. He clones the shared questions, steps, and fees, then overrides the labels and the required flags that actually differ, parents' IDs at kindergarten, motorcycle plates at 22 lei versus car plates at 56. That is cheaper than maintaining two trees that drift, and it is more honest than a single checklist that lies to half the room. The rule for any procedure product is to find the seven common requirements before you design the fourteenth unique one. Clone first. Override second. If a change to a question does not propagate, you do not have a system. You have a pile of copies.
