Version 1.0 — Initial release. This paper presents a consistency test of the Causal Space framework by comparing its induced large-scale deformation effects with the Planck TT power spectrum. Rather than proposing a replacement for ΛCDM, the analysis examines whether the causal-space–induced deformation remains observationally admissible within the low-ℓ regime of the cosmic microwave background spectrum. The study focuses on structural compatibility rather than parameter fitting. It evaluates whether the deformation introduced by the causal mapping can remain bounded within observational uncertainties while preserving the established high-ℓ agreement of ΛCDM. No new cosmological parameters are introduced. The analysis is conceptual and consistency-based, serving as a bridge between the foundational theory developed in the first paper and potential empirical constraints. This work does not claim empirical confirmation. It establishes that the causal-space framework does not contradict current Planck TT observations at the level examined.
