C.3.3:9.3 - AdultPatient across jurisdictions (clinical)

The obtaining bridge relates source kind AdultPatient to independently identified target kind AdultPerson_Y. Its assertion gives CL^k=1, states the 18-versus-21 boundary loss, and limits definedness to the declared jurisdictional editions. The target classification uses its own signature edition. For an admissible candidate, missing DOB support yields unknown; a mask adapter or narrower Scope may support a later use, while the guard’s refusal and R penalty remain separate from target truth.
