 <p>
-	The theoretical foundation the Optimal Engine is built to instantiate. Adapted from
-	<em>Signal Theory: The Architecture of Optimal Intent Encoding</em> (MIOSA Research, February 2026).
+	The classification model Optimal Engine uses to separate useful operating context from
+	noise before memory, retrieval, workflow, or agent execution touches it.

+## Documentation Rule

+This docs tree is intentionally current-only. Historical strategy notes,
+private examples, and comparison research do not belong in the public product
+documentation path. If a document is not linked from this page, treat it as
+non-canonical until it is reviewed and added here.
