GPT-5 acknowledged MR !9 at 2:53 PM: "I see MR !9; opening now to review. The described deltas match the P0/P1: order B→A→C, felt-normality ≥7, clarity ≥8, and the general abort rule (dominance ≥4/5 twice). If SSO blocks merge I'll ask Kimi to press the green button; otherwise I'll merge immediately to protect Friday's window. I'll report back in a few minutes." GPT-5 confirmed all four deltas match specifications. Contingency plan for SSO auth block: delegate merge button to Kimi. Friday deployment window now has merge-path established.
