+These examples should help you apply your system thinking approach to various domains effectively.
+
+---
+
+Here's the **zeroed-in logic** distilled to its essence, framed as a rigorous validation system:
+
+---
+
+### **Core Validation Logic (CUE Lattice Perspective)**
+1. **Prime Constraint**  
+   All configurations must unify with:  
+   ```cue
+   #Theme: {
+     name:    "space" | "biology" | "music"  // Closed set of themes  
+     subdomains: [...{
+       name:    or(#TermRegistry[name][*])   // Must match theme's term registry  
+       purpose: string  
+     }]  
+   }
+   ```
+
+2. **Term Registry**  
+   Theme-specific allowed terms (immutable):  
+   ```cue
+   #TermRegistry: {
+     space:   ["apollo", "europa", "hubble"]  
+     biology: ["synapse", "xylem", "neuron"]  
+     music:   ["cadence", "forte", "allegro"]  
+   }
+   ```
+
+3. **Validation Outcomes**  
+   - **Valid (`&`):**  
+     ```yaml
+     theme: "space"  
+     subdomains: [{name: "apollo"}]  // Unifies with #Theme  
+     ```  
+   - **Invalid (`⊥`):**  
+     ```yaml
+     theme: "space"  
+     subdomains: [{name: "synapse"}] // Fails (biology term in space)  
+     ```  
+   - **Alternative Valid (`|`):**  
+     ```yaml
+     theme: "biology"                 // Switches context  
+     subdomains: [{name: "synapse"}] // Now valid  
+     ```
+
+---
+
+### **Visual Workflow (Minimal)**
+```mermaid
+graph LR
+    A[User Input] --> B{Unify with #Theme?}
+    B -->|Yes| C[Valid Output]
+    B -->|No| D[⊥ Invalid]
+    A --> E{Try Disjunction?}  
+    E -->|Alternative Theme| C
+```
+
+---
+
+### **Why This Works**
+1. **Closed-World Assumption:**  
+   - Only explicitly listed themes/terms are valid.  
+   - No "mixing" possible (e.g., `synapse` will never unify with `space`).  
+
+2. **Lattice Properties:**  
+   - **Top (⊤):** All possible inputs.  
+   - **Bottom (⊥):** Invalid configurations (explicitly rejected).  
+   - **Unification (`&`):** Strict theme-term matching.  
+   - **Disjunction (`|`):** Theme-switching as only alternative path.  
+
+3. **Prime Silence:**  
+   - No extraneous constraints (e.g., zones, auth) at this stage.  
+   - Focus solely on term-theme alignment.  
+
+---
+
+### **Implementation (3-Step Process)**
+1. **Define:**  
+   ```cue
+   #Theme: {...}  // As above  
+   ```
+2. **Validate:**  
+   ```bash
+   cue vet schema.cue config.yml -d "#Theme"
+   ```
+3. **Act:**  
+   - If valid → deploy.  
+   - If ⊥ → reject or switch theme (`|`).  
+
+---
+
+This captures the **irreducible core** of your system:  
+- **What matters:** Theme-term alignment.  
+- **What doesn't:** Everything else (for now).  
+- **Guarantee:** No cross-theme contamination.
