This documentation reflects MetaGuard Pro 2.x (current stable). For older versions, see Legacy Version below.
Unity projects accumulate GUID corruption silently. Broken asset references, duplicate GUIDs, and orphaned .meta files compound over time — surfacing during merges, after directory restructuring, or at release.
MetaGuard Pro scans every asset in the project, builds a directed dependency graph, classifies every GUID integrity issue by risk level, tests every proposed fix against the graph before touching any file, and applies only operations it can verify are safe — with a pre-apply snapshot and 48-hour rollback window on every session.
No file is modified without a recoverable snapshot. No operation reaches Apply without passing simulation.
