flat snapshot record per aggregate - separate files mean saving a run doesn't rewrite the Profile, deleting a slot is deleting a file, and a corrupt slot doesn't cost achievements or best times. snapshots hold primitives so Restore re-runs the value-object factories; a serialiser building LevelId directly would bypass every guard. LoadResult has three outcomes: Absent != Corrupt. Collapsing them is the bug where a version bump made ContinueGame overwrite the save. Profile.Restore writes collections directly - replaying UnlockAchievement would re-fire popups and Steam pushes on every load. 44 tests.
