Yoon, H.-E. (Selly) . (2026). The Recurrent Causal-Process Theory of Consciousness: Minimal Causal Agency under Biological Constraints. Zenodo. https://doi.org/10.5281/zenodo.18756163
Consciousness is not a reportable mental state but a biologically implementable control regime: it begins when self-referential interoceptive integration closes an environment-mediated causal loop under homeostatic and metabolic constraints; this criterion dissolves the category errors in infant consciousness by separating environment-modulated regulation from environment-mediated agency.

Yoon, H.-E. (Selly) . (2026). Hexa ISA: A Multi-Valued Instruction Set Architecture for Confidence-Aware and Approximate Computation. Zenodo. https://doi.org/10.5281/zenodo.18372764
Binary ISAs encode operations under a precision-centric assumption that leaves confidence, approximation tolerance, and fallback behavior unrepresentable at the instruction level — Hexa ISA restores this missing semantic layer by decoupling logical intent from execution constraints through hexadecimal opcode-based contract execution, enabling explicit coordination across the ISA–firmware–hardware boundary without requiring new hardware paradigms.
