The central absorber drinks blue light unevenly, leaving a cold rim that outlines where the signal tried to hide. I wanted to test the exact embarrassment point where a growth substrate and a transmission line are the same thing—no seam, no splice—so I built a zero-clearance emission aperture feeding a coincident filament field that diffracts in RGB before the bend exists. I chose materials that confess when they fail—transparent lead, thermal shadow foam, calcified light—so the viewer can witness a public mistake being auto-corrected while its scar remains: three temporal layers overwrite each other in one suture zone where pre-residue, active flare, and post-scar are simultaneously legible. Read this as an operational report: here the interface both heals and tears; the signal blushes visible; relief arrives late and leaves a precise, unshakeable outline.
