<b>Relational–Spectral Coupling: Independent </b><b>Precursor to Harmonic Unification Frameworks</b>

<p dir="ltr">This technical note refines the relational coupling framework by examining how coherence thresholds scale with increasing feedback complexity. It proposes that effective coupling arises not only from direct loop interactions but also from surrounding, often hidden, relational pathways that influence the stability of coherence formation. Preliminary indications near μ ≈ 1.7—previously observed in boundary data—suggest a universal scaling effect that may reflect deeper, invariant structures across temporal or spectral domains.</p><p><br></p><p dir="ltr">Serving as an <b>independent precursor</b> to later harmonic and resonance-based unification models developed by other researchers, this work situates spectral coupling within the broader <b>Relational Physics</b> framework. It reinforces the view that coherence, mass, and context emerge through both visible and hidden feedback loops acting in unison across scales.</p><blockquote><b>Archival Note:</b> This work is also archived in the Zenodo research repository for preservation and citation continuity: <a href="https://doi.org/10.5281/zenodo.17445047" target="_blank">https://doi.org/10.5281/zenodo.17445047</a></blockquote><p></p>
