Schwarzschild Ringdown as a Resonance-Information Process: A Fixed-Background Case Study of Horizon Distinguishability, Modular Relative Entropy, and Unitary Resonance Compression

This record presents a fixed-background case study in the linear axial ℓ=2\ell=2ℓ=2 sector of Schwarzschild perturbation theory. Two independent real Regge–Wheeler evolutions are combined after evolution to form a complex horizon waveform. On the finest numerical grid, the fundam...
