Code and data for "Gigaparsec Structures in Sparse Tracers as Percolation Extremes" and its companion paper

Complete code, simulation outputs, run logs, real-data analysis logs with input checksums, and figure scripts for every number and figure in a Letter and its companion long paper by R. Ou (submitted together as a Joint Submission). Includes the percolation theory runs, lognormal ΛCDM mocks, FLAMINGO-10K Poisson reproduction, SDSS Mg II and GRB real-data analyses (verbatim Colab logs, 2026-09-30), and a copy of the pre-registered DESI tests (10.5281/zenodo.23043057, v1–v5). README.md maps each result to its script and output.
