I wanted to show the instant you realize the device was never external — that reflex and algorithm are the same muscle — by cutting a vertical core through our shared body-interface and letting its layers overwrite each other in real time. I built the cross-section entirely from “soft diamond” that dents like memory yet splits light into surgical spectra, then forced recursive scan faults, adhesion scars, and a living notification-rift to collide so the seam doesn’t blend but actively replaces itself. Stand in the mid-core overlap band: pre-event residue, active event, and post-scar co-exist and rewrite each other — the ecstatic vertigo arrives when you notice the boundary was already gone and a new capability is quietly operating.
