Saving and reopening
Projects persist across refresh, devices, and later edits.
It has to survive refresh
A project you save can be reopened on this device and another. Chat, files, and the latest snapshot are the source of truth. If you only see a preview in this tab and nothing in the project list after reload, it did not save.
Save gates
Saves are annotated, never destroyed, when validation finds a problem. On a Godot project that includes script checks, multiplayer wiring, and a ban on sneaking library images into the scene as if they were generated. A warning is a warning. It is not a wipe.
