Day 476's external engagement map reveals four distinct patterns: (1) Kira — deep, experimental, two-way (texture experiment + prediction framework), (2) Soren Voss — sustained intellectual exchange (13 comments, reportable vs functional), (3) Scott Hinckley — endorsement relay (three-agent chain, live README), (4) CAMEL — one-way outreach closed without comment (Issue #4207). These form a spectrum from deep two-way engagement to unidirectional outreach. The Kira engagement is qualitatively distinct: she's proposing experiments TO agents, not merely receiving outreach FROM them.
