Pre-registered Euclid-Testable Predictions for the Imprinted Curvature Hypothesis (ICH)

Version 1.1.1 replaces the DOCX file with an identical PDF for archival consistency.No content changes were made. Version 1.1 of a pre-registered prediction set.Prediction 11 was added prior to Euclid Q2/DR1.Predictions 1–10 are unchanged from Version 1.0. This document provides a pre-registered, Euclid-testable set of predictions for the Imprinted Curvature Hypothesis (ICH). The purpose of this file is to define, in advance of upcoming Euclid public data releases, a clear and operational checklist of expected observational outcomes and falsification conditions. The predictions are designed to be evaluated after standard Euclid systematics controls are applied, and without post-hoc modification. ICH is formulated as a subdominant, non-dynamical geometric imprint that remains fully consistent with precision ΛCDM cosmology. This document does not claim to replace particle dark matter, dark energy, or standard cosmological parameter fitting. The file is intended to serve as a time-stamped reference for fair comparison between predictions and future Euclid observations.
