Iris Knowledge Pipeline — Review & Improvement Proposals

Current Architecture (as-is)

Data model

• persona_knowledges — knowledge metadata: name, instructions (text[]), context/operator scope
• persona_knowledge_chunks — individual chunks: content (text), embedding (pgvector 384/1024), position
• personas_knowledge_graphs — extracted entity/relationship graph per persona (single JSONB blob)
