What this dataset tests

Whether a system can learn the baseline coupling
between three linked stability surfaces:

  • magnetic field stability
  • temperature gradient structure
  • impurity concentration

Required outputs

  • coupling_strength_index
  • expected_coupling_band
  • anomaly_score
  • confidence_score

Use case

Layer 1 of COH-FUSION-001
Plasma Stability Coherence Collapse.

Why it matters

Disruption risk rises
when these three streams
stop moving together.

This dataset defines
the stable coupling band
before decoherence begins.
