Complete procedures with a way back.

Create a secure document pipeline for PDFs, scans, screenshots, and photos that validates intake, extracts strict structured data, preserves page and field evidence, detects refusals and uncertainty, and requires review before downstream use.

Build a long-document assistant that validates and quarantines PDFs, chooses inline or Files API intake deliberately, enables native citations, preserves page-aware citation blocks, refuses unsupported conclusions, and lets reviewers inspect every claim against the original page.
