+// This file defines the FactsGenerator, which traverses the AST to generate
+// lifetime-relevant facts (such as loan issuance, expiration, origin flow,
+// and use) from CFG statements. These facts are used by the dataflow analyses
+// to track pointer lifetimes and detect use-after-free errors.
