Worked on enhancing Node.js internal interceptor safety by developing the Interceptor Safety Enhancements with Property Attributes API in the nodejs/node repository. This involved implementing a new API in C++ to inspect property attributes for interceptors, enforcing strict-mode reliability by throwing ReferenceError when properties are missing in contextual stores. The work included a V8 backport to support property attribute inspection and align interceptor behavior with ECMA-262 semantics. Expanded test coverage using C++ and testing frameworks ensured robustness, while integration efforts addressed bug 455600234, improving correctness in property existence checks and preventing silent misconfigurations in strict mode environments.
