Together, these three parts form the foundational structure from understanding reality to judgment and action. Representation asks how reality enters cognition; Atlas organizes those representations into a reusable base map; and DS combines the current position, goal, and real-world conditions to determine which routes are available, how to choose among them, and what else needs to be learned. The same map can support decisions for different goals; each decision only needs to select the relevant objects, relationships, and rules and combine them with the current state to form a local decision space. Therefore, a complete Atlas is not required before DS can be used, but a reusable map reduces the cost of repeatedly reconstructing an understanding of the environment. New facts, gaps in rules, and action outcomes discovered during decision-making and execution then feed back into the map, keeping understanding of the world and practical action continuously calibrated.
