# This session context does four critical things:

### **1. Locks the Standard Model into its correct identity**
- Sector grammar  
- Excitation‑based  
- Gauge‑geometry aligned  
- No particle‑object ontology  

### **2. Establishes drift boundaries**
- Prevents metaphysical “particle” drift  
- Prevents overextension into R4  
- Prevents collapse into R1  

### **3. Sets the coherence posture**
- Gauge symmetry  
- Renormalization stability  
- Higgs‑anchored mass structure  

### **4. Makes the module AI‑parsable**
- Every page stands alone  
- Operator grammar is explicit  
- Regime placement is declared
