This Zenodo record documents v1. 0 of the CoreLumen PDE Program prototype. The document reports a numerical observation of amplitude-induced suppression of horizon derivative growth within a reduced axisymmetric effective-field model. Three dynamical regimes are identified: Phase A (geometry-dominated), Phase B (balanced), Phase C (amplitude-dominated suppression). This release is an archival prototype record. It does not claim a full nonlinear Kerr–de Sitter stability proof, a global theorem, or UV completion. All constructions satisfy the CoreLumen Structural Charter v1. 0: Zρ > 0, Zθ > 0, cₛ² > 0, cT = 1. This deposit preserves a reproducible structural state of the project and serves as a versioned research record.
