+/// EscapeTrackedCallback - A SymbolVisitor that marks allocated symbols as
+/// escaped.
+///
+/// This visitor is used to suppress false positive leak reports when smart
+/// pointers are nested in temporary objects passed by value to functions. When
+/// the analyzer can't see the destructor calls for temporary objects, it may
+/// incorrectly report leaks for memory that will be properly freed by the
smart
+/// pointer destructors.
+///
+/// The visitor traverses reachable symbols from a given set of memory regions
+/// (typically smart pointer field regions) and marks any allocated symbols as
+/// escaped. Escaped symbols are not reported as leaks by checkDeadSymbols.
+///
+/// Usage:
+/// auto Scan =
+/// State->scanReachableSymbols<EscapeTrackedCallback>(RootRegions);
+/// ProgramStateRef NewState = Scan.getState();
+/// if (NewState != State) C.addTransition(NewState);

Updated as suggested: constructor is now private, added
