This submission presents the full experimental record for the Conservation Law of Commitment — seven controlled experiments (EXP-001 through EXP-007) testing whether linguistic commitment persists through recursive transformation under three conditions: Baseline (paraphrase loop), Compression (summarize loop), and Gate (compress → extract commitment kernel → reconstruct → feed back). The dataset comprises 57 signals, 181 condition-signal runs, and 10 iterations per run using GPT-4o-mini at temperature 0.

Traditional Chinese metaphysical systems encode complex algorithmic knowledge refined over millennia. Rather than evaluating predictive validity, this work applies computational cultural analytics to study the mathematical structure of three such systems as objects of scientific inquiry.

Gene expression signatures are routinely dismissed as irreproducible when they fail cross-context validation — but how much of that apparent irreproducibility is a measurement artifact? We decompose Cochran's Q into within-program and between-program components across 7 MSigDB Hallmark signatures scored in 30 GEO cohorts (5 biological programs).

We investigate the long-range dependence structure of the Church and White global mean sea level (GMSL) reconstruction (1880–2013) using detrended fluctuation analysis (DFA) applied to the seasonally adjusted level series and rescaled range (R/S) analysis applied to monthly increments. DFA of the raw GMSL record yields a scaling exponent α = 1.

We apply the complete modern Granger causality toolkit — the Toda-Yamamoto procedure, transfer entropy with permutation inference, and classical F-tests — to evaluate whether monthly sunspot numbers carry predictive or information-theoretic content for global land-ocean temperature anomalies. Using the overlapping period of the SILSO v2.

Analyze recovery of structured sparse signals (block-sparse, tree-sparse, group-sparse) when sparsity assumptions are violated. Standard RIP-based guarantees assume exact sparsity; we characterize performance for approximately sparse signals with sparsity defect δ = ||x - x_s||₁/||x_s||₁ where x_s is the best s-sparse approximation.

Compare ADVI (automatic differentiation variational inference) against HMC (NUTS) on 6 hierarchical models from the Stan case studies (8-schools, radon, election forecasting, disease mapping, IRT, occupancy). ADVI posterior means match HMC within 3% (mean absolute deviation).
