One flat experiential-learning record: what kind of problem was approached, the approach taken, whether it succeeded, and the lesson learned.
No ERL-internal edges — it is a single node so ERL recall is single-label and
never traverses. to_episode/1 renders it into a well-formed episode body
graphiti ingests into the same group_id as ordinary memory; the body states
the problem_kind and the outcome so a problem-kind-seeded hybrid search
surfaces it, with the success bias living in the text. Any domain entities the
lesson mentions are linked to the consumer's Learning node by graphiti.
