# Cross‑Module Integration — Standard Model  
### TriadicFrameworks /docs/theories/standard_model/cross_module.md

The Standard Model (SM) is a **sector grammar of excitation modes**.  
Its operators, resonance surfaces, and symmetry structures interact with  
other TriadicFrameworks modules through shared invariants, regime  
boundaries, and substrate‑level geometry.

This file defines how the Standard Model integrates with other theories  
across the canon.

# 1. Quantum Field Theory (QFT)

### **Integration**
- QFT provides the **substrate excitation structure**  
- SM operators map directly onto QFT field operators  
- Renormalization flows originate in QFT

- excitation modes  
- gauge symmetry  
- renormalization structure  

### **Boundary**
SM is a **sector grammar**; QFT is the **substrate grammar**.

# 2. Quantum Mechanics (QM)

### **Integration**
- QM governs **R1 collapse behavior**  
- Phase structure determines excitation stability  
- Mixing matrices (CKM/PMNS) originate in QM amplitude structure

### **Shared invariants**

- phase evolution  
- amplitude geometry  

### **Boundary**
SM collapses in R1; QM dominates.

# 3. Special Relativity (SR)

### **Integration**
- Lorentz symmetry constrains excitation behavior  
- Spin, mass dimension, and dispersion relations depend on SR  
- Gauge geometry must be Lorentz‑consistent

### **Shared invariants**
- Lorentz invariance  
- spin structure  
- energy‑momentum relations  

### **Boundary**
SR provides the **kinematic geometry**; SM provides the **sector grammar**.

- Early‑universe thermodynamics shapes symmetry restoration

### **Shared invariants**

# 10. Cross‑Regime Integration

- **R1:** QM dominates; SM collapses

# Summary

The Standard Model integrates with the rest of the canon through:

- **excitation structure** (QFT)  
- **phase structure** (QM)  
- **symmetry geometry** (SR)  
- **resonance flow** (Thermodynamics)  
- **high‑energy behavior** (Cosmology)  
- **information classification** (Information Theory)  
- **network dynamics** (Complex Systems)  

The Standard Model is not an isolated theory —  
it is a **sector grammar** embedded in a larger substrate.
