knowledge-graph-system vs crg

knowledge-graph-system: Kappa Graph is a semantic knowledge graph system designed to extract concepts and relationships from various documents, providing an epistemic layer that measures the reliability and support of claims. It distinguishes itself by offering grounding scores, detecting contradictions, and preserving the full provenance chain to source evidence.; crg: `crg` (formerly `better-code-review-graph`) is a local-first knowledge graph tool for codebases, enabling token-efficient code reviews through semantic search, call-graph resolution, and structural analysis. It integrates with AI agents via MCP for precise context provision, leveraging local ONNX embeddings or cloud models for enhanced code understanding and security scanning.
