+This ServiceNow business rule script is designed to detect configuration drift in a Configuration Item (CI) by comparing its current state to the most recent baseline record stored in the cmdb_baseline table.
+
+What it Does – In Simple Terms:
+Gets the latest baseline for the current CI.
+Compares key fields (ram, cpu_count, os) between the current CI and the baseline.
+If differences (a "drift") are found:
+It logs the drift in a custom table (u_drift_log).
+It triggers an event (ci.drift_detected) to possibly notify or take further action.
