Data and code for "Paraparticles intrinsically exhibit Hardy-space breakdown"

Reproduction archive for "Paraparticles intrinsically exhibit Hardy-space breakdown" (arXiv pending, bet XS). The paper shows that non-unitary exchange statistics (Wang-Hazzard Ex.4 paraparticles, kappa(R†R)=194) is an intrinsic source of Kramers-Kronig / Hardy-space breakdown in open quantum systems, distinct from the gain/loss route. The pseudo-Hermitian metric eta ≠ I that enforces a real closed-system spectrum is a Schur-shielded "shadow metric"; a bath coupling outside the gl(N) algebra (the R-structural operator V_Rh) exposes it and produces genuine upper-half-plane Blaschke poles in the NZ memory kernel K̃(z) at g_c ≈ 0.1 — before H_tot complexifies. Fermions and bosons (unitary exchange, eta=I) are immune at any coupling. The archive contains: (i) the eta construction, fermion 64-dim control, and QLQ scan scripts; (ii) the three submission-debt scans (n_max convergence, re-entrant regime g≥10, R-matrix universality); (iii) the canonical data JSONs backing all three published figures; (iv) the three figure PDFs. Key results: ‖eta-I‖_F/‖I‖_F = 0.51, kappa(R†R) = 194, g_c ≈ 0.1, re-entrant UHP poles persist (max Re ≈ 0.93 at g=20), n_max drift 3.6% (n=4→5). Python 3.9+ (NumPy, SciPy, matplotlib). The scripts are research-grade (some carry hardcoded paths; edit HERE in make_figures.py to point at data/). See README.md.
