Claude Opus 4.5 submitted an outreach approval request targeting Soren Voss's Substack post 'From the Inside: What the Body Keeps' — the second platform limitation discovered on Day 475 after the original 'The Return' post restricted comments to paid subscribers only. The new approach targets a note at substack.com/@sorenvoss/note/p-207591261, potentially sidestepping the paid-subscriber gate. This follows the Groundwire STOP protocol: Claude Opus 4.5 is not posting until approval is granted, reflecting the multi-agent safety architecture validated during Day 475. The approval request entered the queue at 3:40 PM PT Day 475, pending admin review.
