Verification suite for: Fermionic and Bosonic Sectors from Order-2 Parabose Statistics

Complete verification archive for the paper "Fermionic and Bosonic Sectors from Order-2 Parabose Statistics" (R. Bojahr, 2026). Contains (1) the self-contained C++17 BDD test suite (11 specification files, 72 scenarios / 341 assertions, Catch2 + Eigen, Meson build) reproducing every numerical claim of the paper, with per-section tag filters; (2) an independent pure-Python cross-validation of the key results (singleton j = n/2 theorem via Schwinger reduction, verified through n = 6; ensemble-consistency extension to parabose at every particle number; the truncation-edge artifact signature of anticommutator-form number operators); (3) the evidence CSVs (exchange-phase table, nMax sweep, 56-state J² verification). The truncation protocol (nMax ≥ N + 2, two-truncation cross-check, locked regression scenario) is documented in RUNNING.md and in the paper's Appendix A. Reproduction: unpack paper1_verification_suite.tar.gz, then "meson setup buildDir && meson compile -C buildDir && ./buildDir/paper1_tests".
