"""
TNFR Emergent Integration Engine

This engine discovers and implements natural integration opportunities that
emerge from the mathematical structure of the nodal equation. It analyzes
the deep mathematical relationships between all TNFR engines to identify
unified optimization strategies.

Mathematical Foundation:
The nodal equation ∂EPI/∂t = νf · ΔNFR(t) creates natural mathematical
structures that can be unified across computational domains:

1. **Spectral Unification**: Eigendecompositions appear in FFT arithmetic,
   structural fields (Φ_s, |∇φ|, K_φ, ξ_C), and centralization analysis.
   These can share computational artifacts.

2. **Cache Coherence**: Mathematical dependencies create natural cache
   invalidation patterns. Structural fields depend on eigendecompositions,
   coordination depends on centrality metrics.

3. **Adaptive Coordination**: Phase coordination using Kuramoto order 
   parameter can inform cache placement and prefetch strategies.

4. **Vectorization Opportunities**: Nodal optimizer's vectorized operations
   can be extended to structural field batch computations.

5. **Temporal Prediction**: Multi-scale temporal caching can predict
   structural field evolution based on nodal equation integration.

6. **Mathematical Consistency**: All optimizations must preserve TNFR
   invariants and maintain grammar compliance.
