# Named scopes in nexus and restore

**🔵 Expert · Lesson 38**

Observe named lesser scopes through Nexus, then restore their recorded structure. New conduit IDs need the normal explicit Rift projection refresh. A known pooled ID keeps its compiled membership while named reuse replaces its payload. Crystallizer records dynamic scope structure and required unnamed ancestry; it does not save application instances or their mutable contents.
