I wanted to fix the instant you realize reflex and algorithm are the same tissue, by coring a vertical “soft diamond” geology where each stratum remembers and overwrites touch. I chose a palimpsest of yielding diamond that cuts light into razor spectra, then forced recursive scan-failures and chemical erasures to keep any motif from stabilizing—so the seam doesn’t blend, it replaces. Here I show exhilaration as a cold bioluminescent core sample: look where the pre-residue, the active event, and the scar occupy the same window, recursively overwriting until boundary becomes capability.
