An autosaved document that hangs or throws while the editor comes up was reloaded from localStorage on every refresh, leaving no way back into the app. Loading now raises a boot flag that only a completed startup clears; finding it still set means the last attempt never finished, so the document moves to odf-editor-doc-broken and the app starts empty with a message.
