Paper 1A · v1A.0.96 · Physical Review D
Channel-Level Closure of Four Minimal Einstein–Cartan–Holst Dark-Energy Routes and Perturbation Transparency for Scalar Matter
78%

Closes all four minimal Einstein–Cartan–Holst routes from a quantum bounce to dark energy and proves the Holst sector is invisible to scalar/tensor perturbations — leaving two clean observational kill-tests (LiteBIRD birefringence, SPHEREx fNL).

Technical Verification Companion to the ECH Spin-Torsion Program: ΛCDM+ΔN_eff MCMC Proxy, NaMaster Pipeline Recovery, and a Birefringence Consistency Check with a Spectator-ALP Model
76%

Technical companion to Paper 1A: a 309K-sample ΛCDM+ΔN_eff MCMC null test (ΔN_eff consistent with zero), a NaMaster pipeline validation on synthetic ΛCDM skies, a DESI DR2 w0wa chain (w_pivot +2.5σ from −1), and a spectator-ALP consistency check against the Planck+ACT β = 0.342° measurement.

Paper 2 · v1.7.85 · Physical Review Letters
Testing the Matter Bounce with Primordial Non-Gaussianity: A SPHEREx Sensitivity Recast with a MegaMapper Outlook
78%

Shows fNL = −35/8 is a parameter-free, mechanism-independent prediction of all matter-bounce models, and forecasts SPHEREx will detect or kill it at 4.7–12σ by ~2028 — the decisive bounce-vs-inflation discriminator.

Spectrally Unusual Sources at Scale: A Multi-Survey Catalog of 378,280 Path-C Unique Anomalies and a Native-Trained Novelty Fraction from 37.3 Million Sources and Map Patches
80%

A 378,280-object anomaly catalog mined from 37.3M sources across 7 surveys with one autoencoder architecture — 17.8% of top-ranked objects are new to existing catalogs, plus a NANOGrav free-spectrum fit consistent with matter-bounce γ = 3.0.

Paper 4 · v1.0.209 · MNRAS
Survey-Scale Galaxy Chirality with Equivariant TTA: A Null Real-Space Chirality Dipole, a Quantifiable Monopole-Mask Leakage Channel, and Diagnostic Evidence for a Depth/Morphology-Correlated Canonical-Mask Residual on 8.47 Million DESI Legacy Galaxies (3.2 Million Spirals)
80%

Classifies 8.47M galaxies for spiral handedness with a rotation-equivariant ViT ensemble and finds a null real-space chirality dipole (+0.41σ, rank-p=0.31; A_dip < 6.8×10⁻³ at 95% UL) — the earlier −0.122σ subsample-mask null was withdrawn in v1.0.166 after a provenance audit.

Environmental Dependence of Spiral Chirality: A DESIVAST Three-Algorithm Void Null Test on 56,981 DESI DR1 Spirals, with a Secondary Tidal-Tensor Cross-Check
80%

Cross-matches P4's spiral handedness with DESI large-scale structure (791,635 matched spirals + 56,981 void spirals) and finds galaxy chirality is statistically independent of cosmic-web environment — constraining environment-coupled parity models.
