+Understood. Here's the **strict CUE lattice perspective** applied to your single-domain thematic network documentation, distilled to its essential validation flow:

+
+#### **Key Nodes Explained**
+1. **⊤ (Top):** All possible configurations (both valid and invalid).
+2. **Concrete Values:** User-provided inputs (e.g., `theme: 'space'`).
+3. **Constraints:** Theme-enforcing rules:
+   ```cue
+   #Theme: {
+     name: "space" | "biology"
+     subdomains: [...{name: or(#TermRegistry[name][*])}]
+   }
+   ```
+4. **Unification (&):** 
+   - Valid only if *all* constraints are satisfied.
+   - Example: `apollo.galaxy.local` (valid space term).
+5. **Disjunction (|):** 
+   - Alternative valid paths (e.g., switching to `biology` theme).
+6. **⊥ (Bottom):** 
+   - Invalid configurations (e.g., `synapse.galaxy.local` in space theme).
+
+---
+
+### **Workflow Integration**
+1. **User Submits Config:**
+   ```yaml
+   theme: "space"
+   subdomains:
+     - name: "apollo"
+   ```
+2. **CUE Validation:**
+   ```bash
+   cue vet schema.cue config.yml -d "#Theme"
+   ```
+   - **Valid:** Unifies with constraints → `Valid Output`.
+   - **Invalid:** Fails unification → `⊥`.
+
+3. **Alternative Paths:**
+   - If `theme: "biology"`, subdomain `synapse` becomes valid via disjunction.
+
+---
+
+### **Prime Silence Enforcement**
+- **Unassigned Nodes:** Prime-numbered constraints are explicitly *not* used (e.g., no `#Zone` validation here).
+- **Focus:** Only theme purity and subdomain validation at this stage.
+
+---
+
+This mirrors your lattice diagram precisely, with:  
+- **⊤ → Constraints/Values → Unification → Valid/⊥** as the primary flow.  
+- **Disjunction** for theme-switching alternatives.  
+- No extraneous rules—just the core validation logic.  
+
+Would you like the equivalent CUE schema code for this exact flow?

 Below are six concrete domains where you can drop the same “closed-world, lattice-validated” pattern with almost no change to the meta-logic.  
 For each domain I give:
