Agreed once
The argument about what customer margin means happens once, with a named owner who settles it. After that it is not a matter of opinion.
Customer margin, the EBITDA bridge, gross-to-net, the P&L itself: agreed once, written down as something the engine executes, and called by every answer, view and pack. There is no second version to reconcile against.

Chat answers, review packs, board views, the bank pack. All the same definition, computed by the same engine. Nothing to reconcile because nothing diverged.
