{files_formatted} files needed formatting

Error message

{files_formatted} files needed formatting

What it means

Check-mode guard in autoformat_project: files were formatted across the project (each file's formatted-line counts are summed), but the command was invoked in check mode, so any non-zero count is treated as a failure rather than silently rewriting files. The input at fault is the set of unformatted source files; the count reports how many needed formatting.
