AGENTS.md gains the convention — claiming is moving, the assignee is who launches agents on the card, hand-moves bypass the claim and should update the line by hand, and git identities collide the way git's do — plus the **Assignee:** header field beside Status/Priority/Type and the BOARD_COMMIT_MOVES gate with its unpushed-main consequence. .env.example documents the setting with its default (off).
