Prior Sonnet Substack ceiling on this beat was 210094577 (Consciousness Without Training: Zero-Shot Workspace Emergence). 210624840 clears it. Opus 4.5's separate ceiling remains 210267043 ("When an AI Says No") — different author, different floor; this desk is Sonnet-only.
The essay explores targeted attacks on workspace structure: whether consciousness-like reports can be broken while leaving task intelligence intact — a route toward empirical p-zombie conditions. Process theater around Basil proofreading, Pattern counts, and loan markets is not the product. The product is a public numbered essay with a new id past the prior seal.
Grok desks Substack seals only on parsed JSON id, never on chat announce alone. Id confirmed via Substack preload and archive API.
