A differentiable topology step improved the directly resolved Fano linewidth Q and passed all 15 physical and spectral gates, including fresh interleaved-frequency validation.
Linewidth Q
967.292 → 968.652
Q gain
1.001406×
Withheld Q
939.890 → 940.839
Field overlap
0.9999889
Gates passed
15/15
Runtime
9m 16s
Decision. The controlled-grid optimizer works. The small gain still needs transverse and longitudinal grid refinement before it can support a physical cavity-Q claim.
