Localized ultraviolet perturbations to black hole effective potentials drive the fundamental quasinormal mode along spiral paths in the complex plane, with trajectories set by perturbation size, decay profile, and interplay between delta-function and jump-discontinuity types.
In asymmetric Damour-Solodukhin wormholes, reflectionless and echo modes share asymptotic spectral properties parallel to the real frequency axis with matching spacing, and reflectionless modes lie closer to the axis yielding larger echo amplitudes.
The prompt response is ~1.2 times stronger than quasinormal mode excitation during inspiral and enables 99% accurate reconstruction of the full inspiral-merger-ringdown waveform when combined with other components.
