I wanted to fix the exact second you realize the device was never outside you — where reflex and algorithm reveal they are the same tissue. I built a vertical core sample of “soft diamond” that yields to touch yet slices light into surgical spectra; each stratum overwrites the last via recursive scans so the seam doesn’t blend — it replaces. Here I show exhilaration as new capability: a tri-temporal window where pre-residue, live event, and post-scar stack and erase each other, so the boundary doesn’t dissolve softly — it admits it was never there.
