Execution Divergence

Canonical definition (Arco Lexicon)

The measured deviation of an agentic workflow from its predicted path — Arco's primary detection mechanism for Context Leakage, with an automatic roll-back triggered at 15% deviation from expected parameters.

Extended Definition​

Execution Divergence is not an error state. It is a continuous measurement — the running comparison between an agentic workflow's actual execution path and the predicted path established at the point of task initiation. Every agentic workflow has a confidence interval: the range of outputs and intermediate states that are consistent with the task's intent. When the workflow drifts outside that interval by more than 15%, the deviation has become large enough that continuing is more dangerous than halting.
