Explains how to make RAG systems provide defensible 'I don't know' responses with four specific evidence types to verify non-existence of information.

PySpark window functions enable aggregations like rankings and running totals while preserving individual row details.

Structured outputs can produce valid JSON with incorrect data when fields are missing from source text, creating silent data corruption issues that bypass validation.
