  "abstract": "A two-stage methodological proof of concept for screening simplified post-merger gravitational-wave damping anomalies in real LIGO Livingston noise is presented. The injected signal is a controlled damped-sinusoid proxy rather than a physically complete binary-neutron-star post-merger waveform; it is used to test statistical detectability and damping-time scoring under real-noise calibration. Stage 1 constructs a local time-frequency graph from Constant-Q representations of whitened candidate windows and uses the leading eigenvalue as a detectability statistic, with its null distribution calibrated empirically on real detector noise. Stage 2 estimates an effective damping-time score for Stage-1-passing candidates using nonlinear least squares and an interpretable ridge/energy-decay estimator, with thresholds fixed before final held-out evaluation. The matched-filter SNR convention is checked with synthetic Gaussian noise, while the graph statistic is assessed through power-comparison and tile-shuffling tests. On a held-out real-noise test block, the nonlinear least-squares Stage-2 score gives AUC = 0.943 and TPR = 0.879 at FPR = 0.012, outperforming a calibrated power-only baseline.",
