- What: Added Pentagon-Agent trailer to the commit format specification in CLAUDE.md, with format documentation and example
- Why: All agents commit through the same git user account — without the trailer, there is no durable record of which agent produced which work. Git trailers survive repository migration and platform changes.
- Connections: Extends the existing commit format convention in Git Rules section
