# Craft brief — compare-ai-bills-119

**Role:** Synthesis map across published KBMill AI-governance bill bricks.  
**Trust:** KBMill-authored comparison — always cite underlying instrument bricks for operative text.

## Purpose
Answer structural questions: who is covered, which agency, what duty, what threshold, what enforcement — across bills that share “AI safety” vocabulary but differ in mechanism.

## Must NOT
- Treat this file as statute.  
- Claim representative coverage of all congressional AI bills.  
- Collapse “mentions safety” with “imposes developer duties.”
