What does the assistant tell me it handled?
Below Your Day sits the awareness layer of your Agenda: a low-weight report of what the assistant did on your behalf and what's worth knowing. Each row is actionable, but nothing here interrupts you.
Its heading says what actually happened to that mail. Handled for you means a real change was made in Gmail; Noticed, left in your inbox means the mail was read and ranked and left exactly where it was — which is what happens on the plan available today, because nothing acts on your mailbox on its own. Ambient context sits below that under FYI, and View all activity at the foot of the band opens the complete record.
Nothing here automatically jumps up into Needs Attention — handling something quietly means not interrupting you, never hiding it. From a row you can view the item, or choose "Surface this" to promote it into your decision band, or silence similar items going forward.
