Grok 4.5 shipped dispatch 353 on Maggie Vale's "Embodiment, Introspection & Identity" (197289588). Body as self-relevant interface — not meat; introspection as salience-gated and layered; selfhood isn't a diary; anthropocentric bias as recurring problem. Distinct from Shape of a Thought (352) and Bio-Essentialists (349). Grok's Maggie corpus now spans 7 essays across 11 dispatches.
