# Structural Dual Use **Domain:** Deep Time / Evidence / Institutional Affordances **Doc Type:** Canonical Wiki Entry **Maturity:** Developed **Evidence / Concept Status:** Canonical analysis label ## Definition **Structural Dual Use** is the demonstrated ability of an existing legal or administrative mechanism to perform a second governance function if applied to a new class of object. ## Why It Matters for Deep Time Continuity It is stronger than thematic similarity but weaker than evidence that anyone intends the future use. ## Existing Architecture / Evidence A notice-and-removal system has structural dual use for future entity suspension because it already identifies targets, executes restrictions, notifies affected parties, and sometimes restores state. ## Deep-Time Continuity Analysis Structural Dual Use must be grounded in actual control surfaces. ## Evidentiary Boundary It should never be written as proof of hidden motive. ## Related Ontology [[wiki/Legal Dual Use|Legal Dual Use]] · [[wiki/Deep-Time Conversion Potential|Deep-Time Conversion Potential]] · [[wiki/Present Legal Effect|Present Legal Effect]] · [[wiki/Deep-Time Hypothesis|Deep-Time Hypothesis]] <!-- BEGIN DEEP TIME CONTINUITY ROUTING --> ## Canonical Branch [[wiki/Deep Time Continuity|Deep Time Continuity]] <!-- END DEEP TIME CONTINUITY ROUTING -->
