Fractal Correction Engine (FCE)
===============================

A numerical correction framework that uses Frenet-Serret curvature
feedback to detect and mitigate decoherence in open quantum systems.

The FCE uses the Quantum Frenet-Serret apparatus (Alsing & Cafaro, 2024)
to detect decoherence via curvature anomalies in the quantum state trajectory,
and applies continuous error correction to steer the state back toward
the ideal evolution.

Core modules:
    engine          Main FCE orchestrator (FractalCorrectionEngine)
    fidelity        Uhlmann-Jozsa fidelity and related measures
    lindblad        Lindblad master equation evolution
    frenet_serret   Quantum Frenet-Serret curvature/torsion
    trajectory_predictor  Forward/backward state prediction
    hausdorff       Fractal dimension health monitoring
    qec_continuous  Continuous QEC via curvature feedback
    stabilizer_codes  Discrete QEC (Steane [[7,1,3]])

Scientific rigor modules:
    ablation        Ablation studies isolating FCE contribution
    convergence     Numerical convergence testing
    uncertainty     Monte Carlo uncertainty quantification
    conservation    Conservation law monitoring
    sensitivity     Parameter sensitivity maps (alpha sweep)
    quantitative_validation  Quantitative benchmarks vs analytical references

Application layers:
    navigation      11D navigation with M-theory compactification
    m_theory        M-theory dimensional scaling
    holographic     Black hole entropy, MSS bound
    nonequilibrium  Jarzynski equality, Crooks theorem
    qft_effects     Hawking, Unruh, Casimir effects
    chaos           Lyapunov exponents, multifractal analysis

Output:
    visualization   Publication-quality plots
    data_export     CSV and JSON export
