US GDP — High-Frequency Dissipative System Analysis (1841–2013)

This dataset is part of the Bicameral Solar Engine project, a multi-scalar deterministic framework that maps the relationship between solar harmonic cycles and terrestrial systems including climate, economics, and biological populations. All datasets share a common methodology: raw signals are detrended using an 11-year centered moving average, normalized into Z-scores. 

Applies the BSE solar harmonic framework to US Real GDP (1841–2013, constant 2017 USD), treating economic output as the most downstream signal in the validation hierarchy — the terminal expression of a causal chain running from solar magnetic phase through atmospheric chemistry, biological cycles, and collective economic behavior. Achieves 100% phase-direction alignment across eight 22-year Hale cycle windows. Growth phases produce directional efficiency η = 1.302 vs Decline η = 0.868. The 1927–1948 Decline window — containing the Great Depression and WWII — produces the highest path length (16.74) and most negative bias (−1.961) in the record. Removing this dataset does not alter the core validation.
