AWS outlines an architecture that uses Claude Sonnet 4.6 to extract fields from contract PDFs, Claude Haiku 4.5 to verify them independently, and a database to support queries across contracts. When the models disagree on signature status, the system calls Amazon Textract. The authors say their accuracy test covered only 20 contracts and results will vary by contract format and field complexity.
