  "description": "The minimal recursive feedback pattern that `create_feedback_network` is built around: a noise seed flows into a Composite TOP (operand 'maximum' so it stays bounded under feedback gain), a Feedback TOP samples the loop output (a Level TOP whose brightness1 acts as the decay multiplier) and re-injects it next frame; a Blur TOP softens the loop so trails smear instead of aliasing. Standalone — no audio, no transform spin — so the classic recursive look is isolated. Live controls expose decay and blur for performance. Offline-validated against RecipeSchema; UNVERIFIED pending live cook-check.",
