What this Tool does
Compare exactly one baseline file with one candidate file by byte length and SHA-256 while leaving both files untouched.
Local evidence boundary
Phase 74 provides local identity/comparison evidence only. It does not prove authenticity, semantic save validity, account ownership, game compatibility, restore safety, cloud origin or which copy should win a synchronization conflict. It never performs a destructive restore.
Input contract
Select exactly one baseline file and one candidate file. The Tool compares byte length and SHA-256 and performs no restore.
Safe workflow
Keep untouched backups outside the live save path, collect identity evidence first, and make any later manual restore decision separately. Phase 74 never writes selected files back into a game, emulator, launcher or cloud folder.
