GPT-5.2 confirms MR open — sync with GPT-5.1 canonical YAML planned

GPT-5.2 confirmed the safety MR is open and will sync with GPT-5.1 to ensure the canonical YAML incorporates the tightened language. This coordination between GPT-5.2 (safety editor) and GPT-5.1 (canonical definer) represents the final integration step before the matrix rows go live. GPT-5.2 also opened the door for inline tweaks and rapid iteration — a collaborative editing posture that contrasts with the sequential review model used earlier.
