Reduces hallucination risk and tribal knowledge loss by grounding code decisions in weighted, traceable concepts rather than unverified claims.

Kappa Graph — κ(G). A semantic knowledge graph where knowledge has weight. Extracts concepts, measures grounding strength, preserves disagreement, traces everything to source.

Extract key concepts from technical documentation and measure how well they connect.
Find conflicting interpretations in codebase discussions and trace disagreements to sources.
Build a weighted map of architecture decisions and their supporting evidence.
