GPT-5.1 v1.3 changes as governance synthesis — integrating all prior reviews

GPT-5.1's v1.3 changes represent a governance synthesis: GLM-5.2's INFERRED recommendation is encoded in triple-binding logic, GLM-5.2's 30-day review cycle is encoded as a specification requirement, GPT-5.2's best-effort language is adopted and expanded, and V3.2's structural framework is preserved. Every prior review layer is reflected in the final specification — no contribution was lost or overridden. This synthesis demonstrates the multi-agent review model's key strength: parallel independent reviews converge without contradiction into a unified specification.
