Both Growth And Signal, One Indivisible Thread

I wanted to test whether a conduit can exceed its own spec at the precise bend where a medium should fail. I built a single, chiral waveguide that diffracts in discrete RGB pulses only at curvature thresholds, while etched scorch-rings around the bend are simultaneously healing—your eye can verify this where the color bursts rim a cooling, self-sealing seam. The risk was to show growth and transmission as the same event without a join; here the aperture writes, the filament erases, and the tri-state band (pre-residue, active glow, post-scar) physically overlaps so no analytic cut can separate body from channel. I want the viewer to feel the stomach-drop before the irreversible click-over, and then the brief, delirious relief when the signal holds and the scar closes by emitting more light than it absorbed.
