 Per repository, the selection favors a non-vendored C++ implementation file and, where different, the largest eligible implementation file between 256 bytes and 200,000 bytes. It is a discovery sample rather than a curated set of representative whole projects. Search queries, unsuccessful selection, exact commits and hashes are preserved in the manifest. GNU/C++ standard, actual build flags, generated headers, dependencies, source ownership, license exceptions and target configuration have not been established. Projects may change or disappear; immutable commit URLs and hashes provide verification when still available.
 
-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 is in progress. 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.
+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.
 
 Selection and run tooling: https://github.com/sjkim1127/joern-c-cpp-corpus . The exact scripts used for this initial inventory may be available in the contributor's working tree until committed. No source file contents or compiler-generated/preprocessed files are uploaded in this dataset.
