Walkthrough

A new static validation status document (.validation-status) has been added to record project validation results, including validation metadata, categorized checks, code quality summary, and recommendations. The file is read-only and does not alter code behavior.

No code was harmed, just wisdom on file,
Our checks all catalogued, section by style! ✨
