ToolsEnabled Agent Architecture: Contract-Driven Execution and Byte-Interval Mediation with Fleet V5

ToolsEnabled Agent Architecture (TEAA) places configuration admission, bounded workforces, completion checks, and supported workspace mediation behind a persistent contract interface. We describe the implemented architecture and apply a frozen selection function to Commit0 library-generation tasks using gpt-6-luna at high effort. A finite library of 22 bound policies is evaluated on 6 fitting repositories; calibration supplies an average token allowance and a working replacement margin. The selected function is constant, n1-T1-K0-b1-c0, rather than a successfully fitted task-dependent policy. Its evaluation compares Fleet with independent best-of-N and solo execution on 7 final repositories. The primary record contains 17 completed and 4 unknown cells. Missing outcomes prevent a complete primary paired sign-flip test and prevent a robust positive mean comparison. We retain measured zero scores, failed executions, accounting gaps, and outcome-dependent protocol deviations. The contribution is an integrated software architecture and an auditable application of a selection procedure; these data do not establish a universal optimum, a causal benefit for every subsystem, or superiority beyond the sampled tasks.
