This record preserves photographed handwritten research notebook pages from October 30, 2013, under the working title "Multi-Dimensional Memory Revisited." The notebook pages document an early exploratory construction of what later became the multi-phase number / shared-amplitude framework used in Coherence Geometry (CG). The pages show the development of a multi-dimensional memory structure in which multiple phase-like or directional components are organized through a shared amplitude-like constraint. This document is historically important because it records an early handwritten test run of the shared-amplitude / multi-phase structure that later became central to Coherence-Driven Intelligence (CDI), Emergent Intelligence (EI), and the formal Coherence Geometry framework. At the time of writing, the later terminology of "mu-numbers," "multi-phase numbers," "Coherence Geometry," and "shared-amplitude coherence" had not yet been formalized. In retrospect, the notebook pages show a precursor to the representational idea later developed in the Coherence Geometry Foundations texts: many phase-like degrees of freedom organized through a common amplitude or coherence resource. This record is released as a historical primary-source artifact. It is not a modern technical paper and should not be read as a complete formal derivation. Its purpose is to preserve the developmental origin of a key CG idea and to make the early notebook evidence publicly inspectable and citable. Internal reference: CGI-HST-000001.
