Checks 1–7

The AI Knowledge Base Builder automatically converts company documents, FAQs, and manuals into searchable help centers. It uses document embedding models and semantic search engines. Its context protocol maintains indexed document memory and supports role-based access control. This improves internal knowledge sharing and customer self-service. Users upload files and manage articles through a web interface. Pricing ranges from $19–$79 per month.

outside the census

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
