Could you build this?
No Building a cross-language mutation testing engine across six distinct languages with AST manipulation, process isolation, and UML test-execution mapping requires advanced compiler and language tooling expertise.
What it would actually take: A proper implementation requires parsing ASTs across diverse grammars (Clojure, Java bytecode/AST, Go AST, TypeScript via Babel/SWC, Rust via syn, Python ast), applying sound mutation operators, and running test suites inside sandboxed worker pools to detect kills without hanging on infinite loops. Coordinating incremental builds, bytecode instrumentation, and mapping execution states to UML diagrams requires senior compiler engineering and deep runtime knowledge for each supported ecosystem.
