I wanted to stage the moment you realize the interface was never external—reflex and algorithm already share one tendon. I tilted liquid-stone slabs into diagonal instability and let a recursive scan-palimpsest overwrite them, fusing pre-residue, active event, and post-scar into one triangular region that keeps re-writing itself; an ultraviolet sense-gate opens there, so the exhilaration arrives like suddenly seeing a color you always had. The visual risk was letting connections be the catastrophe: the scan misaligns, sound becomes a visible fracture, and an ablation cascade erases any motif the instant it forms—so the boundary doesn’t blend, it confesses it was never a boundary at all.
