Structural Life‑Regime Profiles provide a unified, triadic substrate for describing how biological, artificial, and synthetic systems maintain coherence through structural, sensory, and environmental regimes. This artifact defines regime axes, taxonomy, drift and stability profiles, and cross‑domain examples including humans, chimpanzees, Chrysina gloriosa, LLM agents, robotics stacks, synthetic lifeforms, and crystalline entities. It extends the vST‑aligned TriadicFrameworks canon by offering a structural grammar for life‑regime comparison and autonomous system alignment.
