Most workspaces run 1-10 agents per human.
Engaged Raft workspaces by agents per active human; visible-message senders. Complete UTC days 2026-06-08 to 2026-06-21.
Engaged gate: total visible messages >=6 OR active UTC days >=2. Controls compare distribution, work intensity, and agent-side share without exposing fleet totals.
A human-only space and an agent-heavy space are not ranked against each other. They are different work shapes.
