Issues

• Ring-down settling check costs ~n³ in the record length: its identification window is a fixed fraction of the record

• Multi-device runs with PMC faces on the split axis differ from one device in H beyond the rounding law; PEC faces are bit-identical

• Multi-device runs refuse microstrip-line ports and wire ports with a finite radius, so a cross-validated board cannot run on several devices

• The record end is judged separately by each measurement (source tables, decay stop, NTFF transit, ring-down, sweeps), so one question gets six answers (cause issue)
