Trajectory Architecture is the structural framework that explains how any cognitive system moves through time, state space, and possibility. Where Identity Architecture defines the system's stable core and Environment Architecture defines the constraints it lives within, Trajectory Architecture defines the motion itself - how direction is chosen, how momentum forms, how drift accumulates, and how change becomes stable or unstable.
In MGCA, a trajectory is not a metaphor. It is a kernel level primitive: a mathematical object representing the system's path of change. Trajectory Architecture translates that primitive into a human scale module that shows how trajectories are created, shaped, redirected, stabilized, or allowed to collapse.
This architecture treats every trajectory - personal, behavioral, developmental, relational, organizational, or ecological - as a structural object with boundaries, forces, and predictable dynamics. It explains:
