Gravitational Wave Chirp Signals are Chirplet-Family: Structural Measurement via Aby Refutation Engine (18 August 2026)

Structural measurements showing gravitational wave chirp signals share 7/8 structural channels with the Chirplet transform and 7/8 with the Wavelet transform, but are REFUTED against the Fourier transform. Measured using the Aby refutation engine (8-channel NPMI methodology, VyroNyx Private Limited, Bengaluru). Implication: LIGO matched filtering is structurally correct in using chirp templates, but Fourier-based noise characterisation may be mismatched to the signal family.
