+    - title: "Implement CppInterOp API Exposing Memory Ownership and Thread Safety"
+      status: Ongoing
+      description: |
+        This project extends CppInterOp with a new API layer that statically analyzes C++ functions and
+        exposes their memory and thread safety behavior using AST. Language binding tools like cppyy can use
+        this information to automatically determine whether a returned object must be deleted by the caller,
+        or whether a function is safe to call concurrently. This is particularly valuable for large scientific
+        libraries like ROOT, where users today must manually handle memory management and thread safety concerns when
+        calling C++ functions from Python. By exposing this information directly from the AST,
+        the project enables binding tools to handle it automatically.
+      mentors: Vassil Vassilev, Aaron Jomy, Vipul Cariappa
