S++ Neural Interface Architecture: Thermal-Neutral Full-Dive BCI Concept (Fairy Dream Protocol)

This document presents the "S++ Neural Interface," a theoretical architecture for a non-invasive Full-Dive Brain-Computer Interface (BCI). The system overcomes critical bottlenecks in immersive technology: dielectric heating, spatial precision loss, latency-induced dissociation, and ergonomic fatigue. Key innovations include: thermal-neutral design via <1% duty cycle + passive fail-safe at 41.5°C; semantic neural rendering (brain as "biological GPU"); distributed compute architecture (zero local heat); cognitive anchoring via UI-free immersion; and predictive latency synchronization (<10ms). This work serves as a conceptual blueprint for academic discussion and future research in immersive neurotechnology.
