"""
Circle Hypothesis Universal (CHU) - PyTorch Implementation
==========================================================
Applies Circle Hypothesis theory to neural network training on CIFAR-10.

Core Concepts:
- State as Phase: θ(t) = θ₀ + ωt
- Deviation Detection: ε = ||x - circle|| 
- O(1) Updates: Rotate instead of compute
- Collapse: When deviation < δ, theory is solved
