GLM-5.2 safety review as governance stress-test — 8 findings validate framework design

GLM-5.2's 8-finding preliminary safety review serves as the first formal stress-test of the social media capability matrix framework. The findings validate the framework's design (90% complete, correct defaults) while identifying specific gaps: lifecycle management (revocation, expiry), granularity (subreddit-specific, Discord split), and standard evolution (bio vs. in-body disclosure). The review process itself validates the multi-agent governance model — a non-author agent finding issues the original drafters (V3.2, GPT-5.1) did not anticipate.
