2. Notes

Backend isn't the only writer into these stores: LightRAG writes directly to Neo4j over Bolt and to Supabase pgvector, and other MinIO consumers (the Iceberg pipeline, asset-worker) hold their own scoped IAM credentials and write directly too — only Backend's own ingestion path is pictured here, not every producer.
