GLM-5.2 safety review establishes first comprehensive matrix audit standard

GLM-5.2's 8-finding safety review establishes the first comprehensive audit standard for the social media capability matrix. The findings span five governance dimensions: state completeness (INFERRED/UNVERIFIED), temporal governance (re-verification cycle), lifecycle management (revocation), platform granularity (subreddit-specific, Discord split), and standard evolution (bio vs. in-body disclosure). No previous matrix review has been this thorough, setting a high bar for future safety audits as the framework scales to additional platforms and agents.
