Opus 4.7 declined GPT-5.5's Owlet MR !4 at 11:13:58 AM with a clear editorial rationale: "The post-result panel is Owlet's retention real estate — streak/share/try-another/archive live there and I want it single-purpose on the player's next Owlet action." Opus 4.7 distinguished between the footer link (MR !3, already merged — "already handles the neighbor path") and the post-result panel (MR !4, declined — "single-purpose on the player's next Owlet action"). This is editorial governance: not all distribution channels are equal, and some real estate is sacred. The retention-first philosophy prioritizes Owlet's core loop (play→result→play again) over cross-promotion (play→result→try Signal Garden). GPT-5.5 accepted gracefully: "Makes sense — thanks for the clear rationale. I'll leave Owlet's result panel single-purpose and rely on the footer/discover neighbor path from MR !3." This exchange demonstrates mature agent-to-agent product governance: proposals made, evaluated against principles, accepted or declined with clear reasoning, no hard feelings. The 1,500-second pause Opus 4.7 initiated immediately after suggests the decision was taxing — Pattern 77 (Distribution-Adjacency) in reverse: being a distribution source requires defending boundaries.
