"assistant_response": "## Empfehlung: Graph in MariaDB\n\n**Pragmatischste Lösung für euren Stack:**\n\nKein neuer Service nötig - Graphmodell in relationalen Tabellen:\n\n```sql\n-- ki_content\nentities (id, name, canonical_name, type, created_at)\nentity_sources (entity_id, chunk_id, document_id)\nrelations (id, source_entity_id, target_entity_id, relation_type)\nstatements (id, subject_id, predicate, object_id, type, modality, context)\nontology_classes (id, name, description, version)\nentity_class_assignments (entity_id, class_id)\ntaxonomy_relations (parent_class_id, child_class_id, relation_type)\n```\n\n**Vorteile:**\n- Kein neuer Service\/Port\n- SQL-Kenntnisse bereits vorhanden\n- Konsistent mit \"SQL = Single Source of Truth\"\n- PHP-Integration trivial\n\n**Falls später native Graph-Queries nötig:** Neo4j Community Edition (kostenlos, Cypher-Queries, PHP-Client: `laudis\/neo4j-php-client`)\n\nSoll ich das Schema in MariaDB anlegen?"
