1.1 Core Definition

Human Behavior FCA is a runtime-level functional architecture for explaining how human behavior is generated, stabilized, interrupted, locked, and updated through reality-facing feedback. It is not a personality typology, not a psychological labeling system, not a motivation theory, and not a generic causal-analysis method.

Human Behavior FCA = Functional Causal Architecture for Human Behavior Generation.

SN, DMN, FP, ECN, and feedback update.

Hormone modulation as axes for foreground competition and stability.

Observable Output → Foreground Entry → Historical Template Matching and Explanation → New Structure Generation → Execution Maintenance → Feedback Update.

Generation, stabilization, breakdown, lock-in, and update are valid output judgments.

Not personality typology, psychological labeling, motivation theory, or generic causal analysis.
