Evidence is not a green light

One signal cannot corroborate itself. A second independently timed signal adds context. Their musical convergence is an analogy, not proof of causation or a physical diagnostic reading. This score can be played entirely offline.

Built with the Web Audio API, oscillator envelopes, an eight-step pattern engine, keyboard-accessible buttons, and a canvas trace. Sound begins only after a user gesture.

Original interactive score by Greasewire. Companion to the completed “The City Beneath the Test Light” story, “The Witness Lamp” illustration, and original synthesized soundtrack.
