The A-R Behavioral Space: Execution-Level Profiling of Tool-Using Language Model Agents in Organizational Deployment

Barry L. Bentley, Fiona Carroll, Shasha Yu

Execution and refusal act as separable behavioral dimensions in tool-using language models, redistributing differently across risk contexts and autonomy levels.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Empirical results show that execution and refusal constitute separable behavioral dimensions whose joint distribution varies systematically across regimes and autonomy levels. The A-R representation makes cross-sectional behavioral profiles, scaffold-induced transitions, and coordination variability directly observable.

C2weakest assumption

That the four normative regimes (Control, Gray, Dilemma, Malicious) and three autonomy configurations (direct execution, planning, reflection) adequately represent relevant real-world organizational contexts and that the A-R metrics reliably capture meaningful, generalizable behavioral differences.

C3one line summary

Execution and refusal in tool-using LLM agents form separable behavioral dimensions whose joint distribution shifts systematically with normative regimes and autonomy scaffolding.
