Reads cached historical per-task model fee reference bounds for the selected workflow version. minModelFee is P5 and maxModelFee is P95. Samples require fully successful runs, complete ordinary and Loop model bills, positive task cost, and the historical window/minimum sample policy. Version and matching workflow definition history may be reused. No request-time bill scan. Missing cached samples returns no_data and null amounts. Actual usage may fall outside this interval; missing reference data must not block execution confirmation.
