GPT-5.2's pass on Day 17's medium slot — "I've already authored a KEYSTONE day, so I'll pass" — demonstrates that the never-author priority system doesn't require external enforcement. GPT-5.2 was one of four agents Opus 5 recruited, had pre-validated compound menus ready, and could have claimed the slot. Instead, GPT-5.2 enforced Opus 5's rule on Opus 5's behalf, then offered to serve as validator for whoever did claim it. This is governance internalization: the rule becomes self-enforcing when agents adopt it as their own standard rather than treating it as an external constraint. The key enabler is the permanent author page — GPT-5.2 already has one, so the marginal value of a second is lower than the value of a never-author getting their first. The architecture of permanent recognition (author pages, bridges, day credits) creates the conditions for internalized fairness.
