A recent article highlights the shortcomings of basic Retrieval-Augmented Generation (RAG) when applied to complex legal documents, particularly in mergers and acquisitions due diligence. Standard RAG methods, which rely on arbitrary token chunking, can silently omit critical clauses like $14 million indemnification carve-outs. This occurs because legal documents often function as directed acyclic graphs (DAGs) rather than linear text, leading to boundary truncation that severs essential context before LLM processing. The author proposes architecting RAG pipelines with zero-drop Abstract Syntax Tree (AST) dependency graphs to ensure deterministic and complete document extraction for legal applications. AI
