Declared model
- Dense complex quadratic eigenvalue solve using SciPy, in serial.
- Straight circular isotropic BEAM2 shaft, centered rigid axisymmetric disks and fixed global spin axis.
- Small perturbations, undamped and unprestressed conditions.

Gyroscopic modal & Campbell
A bounded serial route for a straight BEAM2 shaft and centered rigid axisymmetric disks under constant signed speed. Campbell tracking is an orchestration layer over this solve.
Visible limits
- Internal refinement and analytical checks establish bounded numerical evidence.
- The high frequency pair remains ambiguous at 100 rad/s.
- No forced response, unbalance amplitude, general damping, nonlinear rotor or validated critical speed prediction.
