A knowledge graph should explain where each fact came from
Graph extraction is only the beginning. Enterprise users need to know which document supports an assertion, when it was valid, when the system learned it, whether a reviewer approved it, and what happened when sources disagreed.
We treat extracted facts as candidates that pass through schema validation, grounding, confidence checks, and review before materialization. The graph becomes a navigable evidence layer rather than an untraceable collection of AI guesses.
