Structural Cosmology v3.9 presents a precision cosmological framework built upon the statistical inference foundation established in v3.8. This work extends the multi-survey integration architecture (v3.7) and Bayesian inference pipeline (v3.8) toward percent-level constraints on core Structural Cosmology parameters. The framework investigates the feasibility of precision cosmological analyses through cross-survey consistency testing, covariance modeling, systematics control, emulator validation, robustness diagnostics, and extended falsifiability assessments across seven major cosmological probe families: Euclid DR1 DESI DR2 LSST Y1 CMB-S4 SKA Phase 1 GW Standard Sirens SN Ia Pantheon+ A central objective is the evaluation of the Geometry–Growth Projection Test (GGPT), whose primary illustrative prediction is a geometry-growth discrepancy of approximately Δ(fσ₈) ≈ −5% to −7% at redshifts z ≈ 1.0–1.5. The complete figure collection (Fig.1–Fig.89) documents the progression from nonlinear structure formation and higher-order statistics (v3.5), through Euclid DR1 integration (v3.6), multi-survey integration (v3.7), Bayesian statistical inference (v3.8), and precision cosmology (v3.9), providing a unified roadmap toward future investigations of the structural origin of gravity (v4.0).
