  Derived from the published source. Persona stores memory as a Graph-Vector
  hybrid in Neo4j: a per-user personal knowledge graph of typed memory nodes and
  relationships. The HTTP API exposes User, ingest, and query; the entities below
  are the underlying model referenced in the codebase.
entities:
- name: User
  description: A memory namespace, addressed by user_id (^[a-zA-Z0-9_-]+$).
  api_addressable: true
- name: Memory
  description: >-
    Unified memory record. Every ingested item becomes one of three memory
    types — Episode, Psyche, or Goal (AGENTS.md "Unified Memory Model").
  subtypes: [Episode, Psyche, Goal]
- name: Node
  description: A concept/entity node in the knowledge graph (name, properties, embedding).
- name: Relationship
  description: A typed edge between graph nodes (source, target, relation).
