When does the assistant act on its own?
Today it reads and prioritizes your mail and tells you what needs you — and leaves your mail where it is until you act on it. Triage happens without being asked; touching your mailbox does not.
Having routine mail handled for you quietly — silenced, filed, reported as spam — is a set of behaviors you switch on yourself under Account → Automation, and it's part of the Lonzo Assistant plan, which is coming soon. Each one starts off. Once you turn one on, that configuration is your authorization and it acts on that kind of mail without re-asking, reversibly and with a record in Activity.
The safe default always wins: when in doubt, it asks. Anything sensitive, anything that leaves your account, or anything hard to undo is presented to you as an approval before it happens — no setting turns that off.
