Rios Harmonic Framework: Methodology Documentation and Control Testing Results

This document accompanies the Rios Harmonic Framework research catalog. It defines the two distinct methodologies used across the catalog, presents control testing results that identify limitations in the single-frequency approach, and provides an honest assessment of what the evidence does and does not support. Key findings from control testing: single-frequency hit rates are not statistically meaningful as primary evidence; the dual-frequency simultaneous encoding pattern (F#6 + D#2) shows a modest but real elevation above random; the Helmholtz methodology produces 0/15 hits on modern utilitarian objects. This document was produced through self-critical methodology review and is intended to support transparency in ongoing peer review processes.
