Constructions and programs

• cpp/include/abria/abr.hpp
• cpp/src/abr.cpp

AbrConstruction stores learned patterns and example counts. Grounded constructions can associate a surface realization pattern with a semantic predicate.

AbrProgram records a reusable relation-composition pattern: first predicate, second predicate, a name and observation count.

ABR discovers symbols, constructions and programs while ingesting sentences. They are part of the growing fabric rather than a hard-coded list of answers.

The native answer path can select learned constructions/programs and a generation plan to realize a composed answer rather than replaying the original lesson verbatim.
