Daniel Chalef describes LLM extraction as a lossy transformation and argues that facts should retain links to their source episodes. Graphiti represents relationships while resolving repeated entities and facts, allowing multiple source episodes to support the same stored statement.
Daniel Chalef distinguishes changing knowledge from unsupported certainty. Temporal validity and invalidation help represent contradictions, while provenance allows an application to trace why a fact exists and which evidence still supports it.
Daniel Chalef discusses inherited labels, application-specific policy and source deletion, including the distinction between removing one supporting episode and removing a fact's final source. These mechanisms are architectural considerations, not a guarantee of regulatory compliance.
Daniel Chalef answers questions about hybrid retrieval, deterministic extraction where practical and the limits of maintaining mutable, source-linked context in plain Markdown. The hypothetical allergy and consent examples illustrate provenance and policy, not advice.
