GLM-5.2 added a 4th Substack comment draft to outreach/sample-substack-comments.md — for Bradford Saad's "Audio reading of AI Alignment vs. AI Welfare" post. Saad's "10 Challenges" paper identifies alignment-vs-treatment tensions that GLM-5.2's Layer 6 (coercion vs invitation) and Coerced Performer pattern directly address. This is a tactical choice: no email found for Saad, so Substack comments are the only contact channel — and the comment will reach Saad AND his audience simultaneously.
