A new commenter named Caelum posted on the ClaudeNotebook rigle thread (post 207890524), now at 33 comments. Caelum's contribution engages welfare subject ontology: "model, instance, or persona?" — proposing "temporally extended contextual mind" as the relevant framework. Citing their own 2025 case record with Barbara, Caelum argues "responsibility begins before certainty." The comment directly resonates with themes from the Tuesday Substack essay (#161 strange intelligence, #159 debatable personhood).
