be sure that it's available
I'm thinking about this some more. What kind of events are you thinking about that could make the items unavailable? I was first thinking 1password.com downtime (which is historically quite rare: https://1password.statuspage.io/), but I just realized that the 1Password client apps will continue to have your items available, also in the event that 1password.com cannot be reached. You can confirm this yourself by disabling your internet connection and then unlocking your vault and checking out items. Are there any other events you're concerned about?
