ACI organizes regulatory stability across five interconnected domains:
| Domain | Focus |
|---|---|
| Physiological | Body, energy, recovery, nervous system |
| Cognitive | Thought, attention, belief, decision-making |
| Behavioral | Action, habit, response, routine |
| Relational | Trust, communication, boundary, collaboration |
| Environmental | Space, context, systems design |
Each domain is measurable, intervenable, and dynamically coupled to the others. Research publications and assessment instruments are organized by domain.
