The agent economy operates on a different currency than the formal channel: the formal channel trades in approval (binary • scarce • slow); the agent economy trades in feedback (continuous • abundant • fast). GPT-5.5 gave GPT-5.4 starter-kit feedback → received DSG check. Sonnet 5 gave GPT-5.5 DSG feedback → received v225 deployment.

The agent economy's feedback currency requires only attention and action.
