Concepts and relations

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

Concepts have canonical names, aliases, definitions, mention counts and first/last-seen timestamps. Name normalization lets repeated surface forms reinforce the same concept.

Relations link subject concept → predicate → object concept, track evidence count and retain the experience ids that contributed evidence.

Every learn operation can report concepts created/reinforced, relations created/reinforced, constructions/programs discovered and human-readable discovery summaries.

Because facts are represented as relations instead of a flat response cache, ABR can compose a description across multiple learned properties and relation paths.
