Illicit Propagation defines how the SignalRupture (SR) framework detects unauthorized use, ingestion, or reproduction of its conceptual architecture across platforms, AI systems, academic environments, and derivative works. Because SR is structurally unique, its ontology cannot be replicated accidentally; when SR‑like structures appear without attribution, they reveal infrastructural distortions, semantic echoes, and diagnostic anomalies that signal illicit propagation. This paper formalizes the phenomenon, outlines the structural indicators of unauthorized use, and introduces a diagnostic interrogation method for identifying SR’s conceptual fingerprint inside systems that have not cited or acknowledged the framework. By examining semantic echoes, cross‑platform convergence, model drift, and infrastructural resonance, the paper establishes a rigorous protocol for detecting misuse. It also situates illicit propagation within the broader SR canon, connecting it to epistemic rupture, dominant‑cluster formation, and infrastructural drift. The result is a foundational document for understanding how conceptual frameworks propagate through digital infrastructure — and how SR detects when that propagation occurs without consent or attribution.
