V20: Wave Source Editor

Retained analysis
The open blend menu offers None, Waveform Blend, Spectral Blend and smooth forms of each. Interpolation is an explicit construction decision, not an assumed property of the input cycles. Choose it alongside phase relations and the desired transition; a still waveform does not establish how intermediate frames sound.
Documentation and visible configuration; not a new native audio test. Project observations are distinct from the source author's claims.
