> **Real-Time Implementation Layer for Limit Cycle-Based Aviation Safety Models**

OSEF translates validated limit cycle dynamics theory [[Baladi et al., 2025]](https://doi.org/10.17605/OSF.IO/RJBDK) into operational real-time supervision for aviation safety applications.

## 🎯 **What is OSEF?**

OSEF is a **computational framework** that:

- 📊 **Monitors** aircraft trajectory in 3D phase space (Pitch, Bank, Power)
- 🔍 **Detects** Creative Chaos Zones (CCZ) in real-time
- 🎯 **Guides** crews toward stable Limit Cycle operations
- ⚡ **Operates** at < 8 ms latency on standard hardware

### **Built on Validated Science**

Based on research analyzing **1,247 commercial flights** with **89.3% prediction accuracy**:

> Baladi, S. (2026). *Limit Cycle Flight Dynamics as a Framework for Adaptive Aviation Safety Protocols*. OSF. https://doi.org/10.17605/OSF.IO/RJBDK

## 🚀 Quick Start

### 📦 Installation

```bash
# Clone repository
git clone [https://github.com/emerladcompass/OSEF-Framework.git](https://github.com/emeraldcompass/OSEF-Framework.git)
cd OSEF-Framework

# Install dependencies
pip install -r requirements.txt

# OR use conda
conda env create -f environment.yml
conda activate osef
```

💻 Basic Usage
```
from osef import LimitCycleModel, OSEF

# Initialize Limit Cycle Model
lc_model = LimitCycleModel.from_baladi_params()
lc_model.compute_limit_cycle()

# Initialize OSEF
osef = OSEF(lc_model, sampling_rate=8)

# Process real-time flight data
result = osef.process_sample(t=10.5, P=2.3, B=-5.1, W=0.78)

# Check system state
print(f"State: {result['state']}")
print(f"λ: {result['lambda']:.3f}")
```
