Module author 

The strict authoring layer — Ap242Author, one validated constructor per AP242 entity.

Structs

Ap242Author

Strict AP242 authoring handle. Owns the model privately: entities enter only through the generated constructors, so everything inside is AP242 by construction. Ap242Author::finish emits the Part 21 text.

Enums

AuthorError

An authoring-time rejection: the input cannot be part of a strict AP242 model. These fire while an adapter is being developed; a correct adapter never triggers them.
