COCM: Consolidated Technical Monograph v2.0 — Bounded Effective Cosmological Framework: Observational Basis, Formal Bridge, and Corpus Traceability

Version 2.0 (15 May 2026). Extended monograph incorporating new theoretical results derived in the second session of the COCM programme. Principal additions: (1) brane tension asymmetry condition τ_C₀ ≫ τ_Rn as the physical origin of J < 0.25 and e > 0; (2) two-way algebraic traceability between the tension ratio, J, and e, yielding the new falsifiable prediction e² ~ J; (3) cosmic string loop hypothesis for R_n, with connection to NANOGrav 2023; (4) connections with fluid dynamics including the Richardson number analogy for J < 0.25 stability; (5) new implications for GR and Hawking thermodynamics — T_H ∝ J^(−3/4), S_BH ∝ J^(3/2), information preservation condition; (6) qualitative discrimination ΛCDM (J=0) vs COCM (J>0) at two levels; (7) ΛCDM vs COCM superimposed H(z) figures; (8) future projection from 1,000 years to 15 Gyr; (9) compatibility and complementarity with Hubble’s theory at three levels; (10) external evaluation note with author response. Version 1.0 (DOI: 10.5281/zenodo.20186699) was 63 pages; Version 2.0 is 83 pages.
