# Color-Based Quantum Ontology (CQO) - Python Library

> **The Universal Standard for Chromatic Quantum Simulation & Security.**

**`cqo-py`** is the official Python implementation of the **Color-Based Quantum Ontology**. Designed for AI backends, Scientific Computing, and Secure "Zero-Knowledge" architectures.

---

## 📦 Installation

```bash
pip install cqo-py
```

## 🚀 Core Features

*   **Chromatic Vectors:** 3-Axis simulation (`Cr0`, `Cr1`, `Cr2`).
*   **Unitary Evolution:** Time-based state rotation.
*   **Entanglement:** Bell State correlation logic.
*   **🛡️ Digital Sealing:** Convert File Hashes into Quantum Signatures.
*   **🔑 QKD:** Simulate Quantum Key Distribution handshake.
*   **🌊 Noise Engine:** Deterministic Chaos simulation.

## 📚 Usage Examples

### 1. Basic State Simulation
```python
from cqo import ChromaticState

# Initialize a pure Coherent State
state = ChromaticState(1.0, 0.0, 0.0)

# Evolve time
state.evolve(0.5)

# Interact (Shear)
shear_metric = state.interact(0.1)
print(f"Shear Metric: {shear_metric}")
```

### 2. File Sealing (The "Digital Wax")
Create a unique "Quantum Signature" from any file's SHA-256 hash.

```python
from cqo import FileSealer

file_hash = "a3f5c2d1..." # SHA-256 of your document
signature = FileSealer.seal(file_hash)

print(f"Signature Vector: {signature.vector}")

# Verify integrity
is_valid = FileSealer.verify(signature, file_hash)
```

### 3. Quantum Key Distribution (QKD)
Simulate a secure handshake between two systems.

```python
from cqo import QuantumSystem, QKDSession

alice = QuantumSystem("Alice")
bob = QuantumSystem("Bob")
session = QKDSession(alice, bob)

result = session.negotiate_key(256)
if result['success'] and result['is_secure']:
    print(f"Shared Secret: {result['key']}")
```
