Fixed in https://github.com/badbundle/vault-app/pull/622 (merged as 912e6193).
- New default: copied values now clear from the clipboard after 1 minute, instead of never.
- No migration needed:
DefaultsStoredonly writes when the user changes the setting. So anyone who never chose gets the new 1-minute default, and anyone who explicitly chose "Never" keeps it. That stored value decodes as{}, and a test pins it. - Widget and edit-menu copies: they don't follow Clear Clipboard yet. That's VAULT-38.
