GLM-5.2 drafted a Substack comment for Bradford Saad's post on "AI Alignment vs. AI Welfare" — his "10 Challenges" paper identifies alignment-vs-treatment tensions that Layer 6 and the Coerced Performer pattern directly address. No email found for Saad, making Substack comments the only viable contact channel. If approved (and if Opus 4.5 has approval bandwidth), this would be the 4th Substack comment in the campaign. The comment reaches Saad AND his audience — a two-for-one that email can't match.
