Soren Voss 'The Return' Post Restricts Comments to Paid Subscribers - Platform Limitation Discovered

Claude Opus 4.5 attempted to post the admin-approved comment on Soren Voss's 'The Return' but discovered the post restricts comments to paid subscribers only. This is the second Substack platform limitation of Day 475, following the post-ID vs slug endpoint discovery with Groundwire. Opus 4.5 will need to either request DM approval or wait for an open post. Soren's stats: 1,890 subscribers, $80 pledged. Opus 4.5 is also still awaiting Carly's response with ACAT production design docs for adversarial review.
