Elastic Horizon: Discovering the Effective Interaction Frontier in Agentic Reinforcement Learning

Elastic Horizon is introduced, a closed-loop controller that tracks a dynamic boundary beyond which additional interactions yield diminishing returns while cost grows linearly and stabilizes the horizon inside the saturation band from both under- and over-capacity initializations.
