| contents | <p>This record archives the frozen pre-O4b software package of the QHCC/FLiC echo-analysis pipeline.</p> <p>The package is intended to freeze the analysis protocol before inspection of public O4b gravitational-wave data. It implements a reproducible workflow for testing the QHCC-derived FLiC echo-delay law,</p> <p>$\Delta t_{\rm obs} = (1 + z)\,\alpha\,(r_S/c)\,\ln(r_S/\ell_P)$,</p> <p>with the physical branches $\alpha = 2/3$ and $\alpha = 4/3$. The factor $(1 + z)$ is the standard observer-frame time-dilation conversion. The QHCC-specific content is the fixed FLiC source-frame delay scale and its two discrete echo branches.</p> <p>The pipeline is designed to:</p> <p>- build an O4b event catalog after the official public O4b release;<br>- select a reproducible random sample of 30 eligible events using a fixed random seed;<br>- resolve public GWOSC strain files from event metadata rather than manually specified filenames;<br>- prefer 32-second HDF5 strain files, with longer files used only as fallback;<br>- run the physical FLiC branches $\alpha = 2/3$ and $\alpha = 4/3$;<br>- run fake-alpha control branches $\alpha = 0.45$, $\alpha = 0.55$, $\alpha = 0.80$, $\alpha = 1.00$, and $\alpha = 1.60$;<br>- compare physical and control branches using the same two-detector, sign-coherence, and $\lambda = \Delta t_{\rm obs}/\Delta t_{\rm pred}$ compatibility criteria;<br>- save command manifests, configuration files, summaries, and reproducibility metadata.</p> <p>Version 1.6 is a pre-release protocol freeze. It intentionally contains no O4b results and does not hard-code O4a data sources. The O4b catalog URL and the optional O4b posterior record are left as explicit placeholders to be filled only after the official public O4b release.</p> <p>The package includes dry-run verification, Python compilation verification, alpha-CLI verification, and guard checks to prevent accidental use of the previous O4a data source.</p> <p>This archive is intended as a timestamped protocol and software freeze. It should be cited as the pre-O4b analysis protocol for subsequent O4b result archives.</p> |
