EFC Validation Ledger – Full Revision History

Complete changelog for the Energy-Flow Cosmology Validation Ledger, documenting all structural, methodological, and empirical updates since inception.

2026

2026-02-12 (v2.1) – ISW Consistency Audit v1.1 applied (31329082). Removed tomographic cancellation metric 𝒞 from canonical prediction set. Recomputed A_ISW under fully self-consistent growth-channel implementation (ODE-based D(a), no potential μ′ term). Revised prediction: uniform suppression A_ISW ≈ 0.89 ± 0.03 across tracers. Updated ISW row status from "Completed (no observational conflict; falsifiable prediction locked)" to "Completed (Self-consistent recomputation; quantitative revision)". Deprecated 𝒞-metric in Section 1.1 Phenomenological Constraints. Updated ISW sector in Regime × Observable Matrix to "BG → GRW (growth response only; no direct potential coupling)". Updated ISW planned pipeline entry from 𝒞-metric tomographic test to uniform A_ISW amplitude validation.
2026-02-11 (v2.0.1) – KB synchronization update: Added Section 2.3 S₈ Stage-III Convergence table with DEPRECATED/CURRENT framing (KiDS Legacy 0.815, HSC Y3 0.805, Combined 0.813). Standardized three "Completed" rows to follow the 9-level status system: Galaxy rotation curves → Data Likelihood Test; Δ_F regime transition → Consistency Check; H₀ tension → Consistency Check.
2026-02-11 (v2.0) – Full methodological upgrade: Added Executive Summary with 6-channel validation overview; Status Classification Key (Section 0.1) defining 9 validation maturity levels; Global Parameter Registry (Section 0.2) with 4 parameter tables (Background-Coupling, Growth-Sector, Density-Saturation, Lensing Phenomenology) enforcing frozen-parameter governance; Regime × Observable × Sector Matrix (Section 0.3) mapping 20 channels to parameter dependencies. These additions establish canonical governance preventing hidden tuning and ensuring parameter-lock consistency across all EFC validation tests.
2026-02-11 (v1.9) – Methodological refinements: adjusted status wording on 5 rows to improve epistemological precision (High-z null → "null-prediction consistency check"; JWST ΛCDM → ⚠️ with interpretation caveat; Cluster merger → "structural exclusion test"; SCE → "meta-model evaluation"; CMB TT → "Boltzmann validation pending"). Added 8 planned validation rows covering critical cosmological tests: P(k,z) full-shape, CMB TE/EE/φφ, multi-epoch RSD, E_G slip, BAO anisotropic split, BBN expansion-rate, galaxy bias, and global parameter-lock test.
2026-02-11 (v1.8) – Added covariance-aware BAO consistency test using official BOSS DR12 consensus likelihood with full 6×6 covariance matrix (31314922). Fixed-parameter transfer test shows Δχ² = −2.4 for BAO and Δχ² = −0.6 for cosmic chronometers. No validated geometric channel penalises EFC relative to ΛCDM.
2026-02-10 (v1.7) – Major hierarchical restructuring. Added master row "Late-time background coupling architecture (β·T(a))" establishing multi-channel consistency across BAO, RSD, SN Ia, and CMB lensing (31304980). Added "High-z null regime consistency" demonstrating T(z) predicts near-zero modification at z ≈ 3 (31304995). Added "Structural coherence across regimes (SCE evaluation)" for framework-level disciplined assessment (31305550). Updated BAO+RSD and BAO transfer rows with superseding references. Added β-split test and standard sirens to Planned Pipeline (31305421).
2026-02-09 (v1.6) – Upgraded ISW cross-correlation from "Planned" to "Completed (no observational conflict)". Added bias-calibrated A_ISW analysis with DESI DR1 tracer windows, cancellation index 𝒞, and kernel decomposition K_μ/K_μ′. All published ISW measurements consistent within 1.6σ. H(a) background sensitivity confirmed (Δχ² < 1). Falsifiable prediction locked: DESI tomographic bins overlapping z_t should show 𝒞 > 0.7 and A_ISW < 0.5. Paper-ready methodology published as 31301953.
2026-02-07 (v1.5) – Added pre-registered cluster shock-front lensing asymmetry test (Directional Lensing Residuals at Cluster Merger Shock Fronts). Defines directional residual estimator A_sig and rotation-null methodology for L2 geometric symmetry discrimination. Status: analysis pending JWST κ integration.
