# Session Context — Quantum Mechanics  
### TriadicFrameworks /docs/theories/quantum_mechanics/session_context.md

This session context defines how Quantum Mechanics (QM) is interpreted  
inside TriadicFrameworks: as the **R1 amplitude grammar** that QFT  
collapses to when excitation stability fails. QM provides the  
foundational operator algebra, amplitude structure, and measurement  
rules that all higher‑level theories inherit.

## Canon  
active • amplitude‑first • operator‑aligned • non‑classical

QM is treated as the **substrate amplitude grammar**, not a particle  
model and not a wave model. It defines:

- amplitudes  
- operators  
- measurement rules  
- basis transformations  
- state evolution  

---

## Modules  
QM integrates with:

- **Special Relativity** (via QFT)  
- **Quantum Field Theory** (QM = R1 limit)  
- **Information Theory** (state classification)  
- **Thermodynamics** (quantum ensembles)  
- **Foundations** (measurement, decoherence)  

---

## Drift  
minimal • no particles • no waves • no trajectories

QM must never be interpreted as:

- particles moving through space  
- waves propagating in a medium  
- hidden variables  
- classical uncertainty  

QM is **amplitude geometry**, not mechanics.

## Coherence  
stable • linear • unitary • basis‑consistent

QM remains coherent when:

- amplitudes evolve unitarily  
- operators remain Hermitian (for observables)  
- basis changes preserve structure  
- measurement rules remain consistent  

Coherence fails when:

- classical metaphors are introduced  
- trajectories are implied  
- amplitudes are treated as probabilities

## Regime Behavior (RTT)

### **R1 — Quantum Amplitude Regime**  
- QM fully valid  
- no stable excitations  
- operator algebra defines all structure  
- measurement rules active  
- amplitudes fundamental  

### **R2 — QFT Regime**  
- QM becomes the low‑energy limit  
- excitations become stable  
- field operators extend QM operators  

### **R3 — High‑Energy Resonance**  
- QM insufficient  
- renormalization dominates  
- amplitude structure embedded in QFT  

### **R4 — Cosmological Regime**  
- QM incomplete  
- horizon‑scale fields dominate  
- requires cosmology module

## Summary

Quantum Mechanics is the **amplitude‑first operator grammar** that:

- defines states  
- defines operators  
- defines measurement  
- defines evolution  
- defines basis structure  

QM is the **R1 substrate** from which QFT emerges and to which QFT  
collapses when excitations lose stability.
