The graph is not the trust layer

The graph is not the trust layer Blake McCarn's Paperless Knowledge Graph is not interesting merely because it lets someone chat with scanned documents. The stronger idea is that retrieval leaves evidence behind…
The paper by Blake McCarn, titled "Paperless Knowledge Graph," introduces a graph-based approach for organizing scanned documents and extracting information from them. The author presents a pipeline that converts source documents into a knowledge graph containing nodes, relationships, and searchable chunks. The author highlights five key decisions that set this approach apart from others in the field:
1. The system preserves the source of truth by treating the original documents as the authority, rather than relying solely on the AI pipeline.
2. Document freshness is verified by comparing exact document IDs and hashes across different data stores, ensuring that any changes to the documents are noticed.
3. The system uses a combination of entity lookups, vector, keyword, and graph retrieval to answer different types of questions, allowing for more sophisticated queries.
4. The repository includes various artifacts that provide traceability and evidence of the system's behavior, such as evidence packs, claim ledgers, trust dimensions, and traceability paths.
5. The model routing is decoupled from the application, allowing for easier maintenance and testing of the underlying model without affecting the user experience.
The author reviewed McCarn's case study and inspected the public repository, but did not reproduce the reported performance metrics or connect the system to his private archive. The paper notes that the repository contains the advertised evidence helpers and audit tools, but lacks a public fixture to demonstrate the claimed accuracy across various document types.
The author suggests running a field test using a synthetic, non-sensitive Paperless archive to validate the system's performance on key metrics such as accuracy, freshness checks, and response time.
