# Paired full-vector spectral transfer

- Initial pole: **1.073154806 -0.000691954i**
- Initial Q: **775.452**
- Optimized pole: **1.073148289 -0.000682125i**
- Optimized Q: **786.621**
- Q change: **+1.440%**
- Held-out median Q ratio: **1.01013**
- Held-out fraction favoring optimized: **0.643**
- Wide-window peak LDOS change: **+4.453%**

The two geometries use the same full-vector grid, exact periodic leads, source,
PML, and topology map.  Initial and optimized modes were reacquired
independently; no 2.5D field, pole, frequency, or Q was carried into this fit.
