Research direction

Start with server/comlogic/upStorageLogic.go at lines 145-155 and inspect how the range variable is passed to UpdateSmartStoragePassWeight. Trace the related service calls and compare their behavior with the analyzer's range-loop finding. Done means determining whether this is a bug, mitigated case, or desirable behavior and recording the appropriate classification.
