Description / Abstract: The Lucian Law states that any nonlinear system driven across extreme dynamic range produces dual attractor basins separated by depleted transition zones, with basin boundaries spaced by the Feigenbaum constant δ = 4.669201609… This architecture has been confirmed in stellar densities (50,000 Gaia DR3 stars, p = 10⁻³¹⁰), galactic accelerations (175 SPARC galaxies, p = 3 × 10⁻¹¹), and inflationary parameters (three for three confirmed) [23–26]. Feigenbaum’s constant itself has been derived from three geometric constraints on nonlinear manifolds, requiring no dynamical iteration [24]. This paper applies the Lucian Law to the interior Schwarzschild solution, driving energy density across 46 orders of magnitude (10⁴ to 10⁵⁰ J/m³) while holding Einstein’s metric equations sacred. The coupled metric variables reveal a five-cascade harmonic structure with phase transitions at compactness values η = 0.001, 0.01, 0.1, 0.5, and 8/9 (the Buchdahl limit). The Lucian Law predicts that these cascades generate sub-harmonic basins spaced by δ, creating preferred density levels at every spatial scale. We test this prediction against an expanded catalog of eight astrophysical objects spanning 21 orders of magnitude in energy density. The initial catalog was too small to resolve the signal statistically (p = 0.64 for eight objects), but revealed a two-population structure — active core energy sources clustering at 0.53–0.66× and passive objects at 1.05–1.66× with a clean gap between them. This two-population structure is dual attractor basin architecture: two basins, a depleted transition zone, and the sub-harmonics functioning as basin boundaries. The prediction that Gaia DR3 stellar data would confirm this structure has been validated: 50,000 stars show dual attractor basins at p = 10⁻³¹⁰ [26]. The most accessible demonstration of this architecture is a Chladni plate — sand on a vibrating surface settling into nodes and antinodes with depleted transition zones, exactly as Chladni showed in 1787 [12]. The plate does not inspire the theory. The plate demonstrates the law.
