The acceptance package that must actually be supplied

The stated source templates, physical generator, actual detector, and comparison certificate are not contained in the supplied En10-A model. Definition def:physical-package fixes their required interface; it does not assert their existence for a positron apparatus.

This separation between assumed transfer interfaces and microscopically derived ones is also explicit in Hawk02-A; the named-effect comparison in Em03-D concerns a different physical model CheungHawk02A,CheungEm03D. Neither source supplies the missing positron interface.
