SIE.Preface:2 - Source authority and receiving authority remain separate

A source owner can define a scheme or publish a value without authorizing the receiver’s decision. A master-data steward can decide an enterprise identity without deciding product release or recall. Systems Engineering can decide configuration and effectivity without owning a cross-source mapping. Data Engineering can operate a pipeline without deciding semantic equivalence. The receiving application or professional practice owns its operational or decision outcome.

SIE makes the semantic premises and losses inspectable, tests them for the named use, and returns unresolved decisions to their direct owners. It does not borrow their authority.
