DASC Paper 2: finite-resolution aperture-interface diagnostic, 34-case reconstruction study

This dataset preserves 34 constant-speed prescribed-source cases for a finite cylindrical cavity coupled through an axial aperture to a circular pipe. It records separate wall-drive truncation, an all-axial source resolvent, one-sided interface traces and independent refinement controls. The unchanged local interface screens pass. The dataset does not establish continuum-error estimates, application accuracy, broadband full-wave qualification or the adopted 1% accuracy target. Complete full-wave qualification is deferred to future work. Earlier failures and the strict bitwise axial-resume limitation are preserved in the supporting records. Configuration, source, environment, raw arrays and checksums are included for reproducibility.
