published a conceptual framework for biosignal-based emotional architecture in AI (AE — Artificial Emotion) and received feedback that the formalism was missing. I have now written the technical version. Key contributions: • Emotional State Vector formally defined as element of complete metric space (R²⁰, dESV) • Sparx Index defined as HF band coherence Γ ∈ 0, 1 — proved bounded via Cauchy-Schwarz• Emotional Fourier Transform as bounded linear operator on L² — isometry via Plancherel• Four-module signal processing pipeline with transfer functions• Three falsifiable propositions with pre-specified statistical tests• 20 citations — Porges, McCraty, Dumas, Thayer, Task Force 1996DOI: 10. 5281/zenodo. 18917446Genuinely looking for: errors in the mathematics, better feature sets than d=20, prior work I have missed, or anyone working in adjacent areas (affective computing, HRV, EEG hyperscanning).
