 The local initial diagnostic ran Rust-Joern in strict mode against raw files. Such files often require headers and macro expansion, so rejections do not measure parser quality. A separate standalone Clang C++17 qualification was attempted on all 578 files: 564 were rejected or lacked build context; 8 compiler-accepted files were rejected by Rust-Joern after preprocessing, and 6 produced no functions. Details and limited owner-only diagnostics are in `diagnostic-summary.json`. Neither that setting nor a successful parse proves the original project's build mode or CFG correctness. Original Joern and trustworthy compiler-backed CFG comparisons are future work.
