Open-source frequency analysis tool implementing the φ-SETI validation protocol from FCLT Paper 56 (Fermi Paradox resolution). Computes δ-proximity of any radio frequency to φⁿ × H1 where H1 = 1420.405752 MHz (hydrogen line) and φ = 1.6180339887. Sweeps 300–30,000 MHz for all φ-proximal frequencies (δ < 0.015). Pre-loaded with known SETI candidate signals (Wow! signal, BLC1, TRAPPIST-1 region, Proxima Centauri direction) and cosmological constants (Planck CMB, Lyman-alpha, OH masers). Includes AI-assisted analysis tab powered by Claude API. Links to 10 open-source astronomy and SETI archives including NRAO, SIMBAD, Planck Legacy Archive, Gaia, SDSS, and MAST. Built as a React/JSX component. To run: paste file contents into claude.ai as an artifact, or deploy in any React environment. Anthropic API access required for AI analysis tab only — all frequency math runs client-side. Companion to FCLT Paper 56 DOI: zenodo.org/records/19821856. Framework DOI: 10.5281/zenodo.19297099.
