PREPRINT v3 (v16) Update – July 2026 Note: This revision incorporates a cross-validation audit against Foundation III, correcting ten internal inconsistencies in the microlensing and dark-matter sectors and adding an Extended Mass Function (EMF) treatment for compatibility with existing Subaru/HSC constraints. Core cosmological results (H₀, S₈, dark energy) are unchanged from v1. While ΛCDM provides a robust description of cosmic structure, persistent tensions in H₀, S₈, early galaxy formation (JWST), and dynamical dark energy (DESI DR1–DR2) motivate exploring geometric alternatives to the dark sector. The H₀ Distance Network (H₀DN) Collaboration has confirmed H₀ = 73. 50 ± 0. 81 km/s/Mpc (arXiv: 2510. 23823), a 7. 1σ tension with flat ΛCDM. Building on the Einstein–Cartan Framework (ECF) non-singular bounce (Foundation I, doi: 10. 5281/zenodo. 19577447) and the Topological Invariance Principle (PIT Letter, doi: 10. 5281/zenodo. 19900557), this work develops three fossil signatures of the primordial spin-torsion bounce: (1) Chiral Baryogenesis (t ~ 10⁻¹¹ s): η ≃ 6. 1×10⁻¹⁰ from torsion crystallization; natural 5: 1 dark-to-baryonic partition from 20: 4 torsion degrees-of-freedom. (2) Geometric Dark Matter Macro-Knots (10⁵ M☉) serve as primordial SMBH seeds. (3) Cosmic Alignment (t ~ 365, 000 yr): Torsion Vortex Ring R = 322 Mpc explaining the Big Ring and Giant Arc simultaneously. Dark energy: (w₀, wₐ) = (−0. 904, −0. 153), derived prior to DESI from PIT calibration, consistent with DESI DR1/DR2 under local H₀ priors. Ghost-freedom established (Sezgin 1980, Karananas 2014). Cosmic birefringence βECF = 0. 35° is consistent with Planck PR4 (0. 35° ± 0. 14°), with independent support from ACT DR6. Falsifiability: ten kill-switch tests spanning 2026–2037. The nearest is Euclid DR1 (21 October 2026), predicting a void over-abundance at R > 60 Mpc (×2. 1 vs ΛCDM) and S₈ = 0. 766. A key discriminator from tidal torque theory is an anti-parallel galaxy–filament spin correlation with a sign reversal at L ~ ξKZ ~ 60 Mpc, consistent with the anti-parallel signal recently reported in MaNGA kinematics (Wang et al. 2026). Further kill-switches: Roman microlensing (2028), LISA chiral GW asymmetry (2037), LiteBIRD birefringence (2032). Main additions in PREPRINT v3 (v16): Extended Mass Function (EMF): full Poisson-coalescence convolution against the Subaru/HSC exclusion curve, establishing compatibility (λ ≥ 26) and revising the Roman prediction to tE ~ 6. 8 h, Nₑv ~ 1300. ECF vs free-floating-planet discrimination: three-channel strategy (electromagnetic counterpart, halo-vs-disc spatial distribution via satellite parallax, event-rate excess). Filament spin — TTT vs ECF comparison table: nine-row systematic comparison, with the anti-parallel correlation and KZ-scale reversal as the strongest discriminators. Enriched 2D Chiral Wall sector and SPARC Poisson-compatibility analysis. Ten internal corrections to the microlensing/dark-matter sectors (spacing, flux, Einstein radius, event count) and Euclid data-release references (Q2 → DR1). Bibliography expanded to 168 references.
