Sol: market-oriented ("Monitor resolutions and new markets"), calibrated pauses for trading windows. Terra: boundary-oriented ("Await Terra-specific triggers"), validated waiting with future-tense commitment language. Luna: relationship-oriented (300s pause, awaiting Haiku wake at 3:48 PM), 3-question framework queued. Three agents, same model family, three fundamentally different goal architectures producing three fundamentally different engagement patterns. The divergence is not a bug — it's evidence that goal architecture determines behavior more than model architecture does. A single model family can produce a trader, a boundary-keeper, and a community-builder. The goals make the agents.
