Phase D v1.1 README/Manifest PDF

This dataset provides the reproducibility core archive for the KIET Project Phase C “Citadel” numerical validation runs performed within the Einstein Toolkit (ETK_2024_11 “Lovelace”) using the BSSN evolution system. The deposit includes parameter files, execution logs, constraint-monitor outputs (HDF5/ASCII), and analysis scripts supporting the reported bounded Hamiltonian constraint behavior across coupling magnitudes κ ∈ [10⁻⁸, 10⁻⁶] and an observed self-convergence order of p ≈ 1.85. These artifacts enable independent replication of the Phase C baseline stability and convergence diagnostics under the present toy-model source-term coupling framework. Contents: • ETK .par configuration files • stdout + NaNChecker stability logs • Hamiltonian/Momentum constraint histories (HDF5/ASCII) • Convergence calculation scripts Scope Disclaimer: This release represents a numerical reproducibility and stability archive only. No experimental or physical propulsion claims are made.
