How AI was used

The mistakes our checks catch were found during an AI-assisted review of the packet and are now caught by deterministic checks.

An AI agent investigated the whole packet with the app’s own tools, identifiers masked, and suggested issues with quotes. Its suggestions appear only on the final computed version, after each quote is found on its page, and a person accepts or dismisses each one.
