 # Deferred Scope
 
 This document owns intentionally excluded features, not a committed delivery plan.
+The [future feature list](future.md) preserves candidate enhancements and open
+questions without changing these exclusions.
 The [architecture policy](../policy/architecture.md) governs changes to these
 boundaries. Implemented behavior belongs in the [configuration contract](../config.md)
 and consumer adoption in the [consumer guide](../consumers/README.md).
