Load this before you start manually testing Umbraco backoffice extensions in the browser. It's a reference collection of validation checks organized by category: configuration, navigation, API debugging, form controls, and workspaces. Each check has an ID (like VC-1, VN-2) and maps common symptoms to root causes. The real value is the quick reference table that tells you exactly which files to load based on what's broken. Can't see your extension? Check configuration and navigation. Save button missing? Hit the workspace checks. It also includes a discovered issues log so you can capture new problems as you find them, which is smart for building institutional knowledge over time.
