A copy is a new draft; the original is not changed. The standard maps are the pack's own: the weekly payment run and the daily cash sweep.
The model draws a map from your words, binding only parts the library has. It is checked by the same rules as a drawn map; what the model could not put right opens marked, and Publish stays locked until it holds. What the model sees is your description, the library and the worked example; none of the company's figures or keys.
Publishing writes a new version the Enterprise service can run. It cannot be changed afterwards; a change is a new version. Shadow stays on: a person turns it off for a run.
