Inheritance

Child models can inherit from a parent and share the same id across tables. Reads auto-join parent fields; writes split by owning table.

class Contact { static name='Contact'; static fields={ id:'primary', class:{type:'reference'}, first_name:'string', last_name:'string' } }
class User { static name='User'; static inherits='Contact'; static fields={ email:'string', password_hash:'string' } }
repo.register(Contact); repo.register(User);

See the CRM demo and the integration tests for end-to-end examples.
