The passage around this formula
…how much autonomy each has, and how the underlying knowledge is represented and accessed [ 13 ] . The engineering consequence of policy-controlled retrieval is the one this family cannot avoid: the round count k from the iterative family’s cost model is, for an agentic system, a random variable whose distribution depends on the policy and the specific input, not a number fixed in advance by the architecture or bounded by a benchmark-tuned heuristic. Absent an operator-imposed budget — a maximum number of…
