Three lines, before anything else competes for attention. What it did, as a running account you can act on row by row, which doubles as the undo surface. What it is doing now, in one sentence. And what can still be taken back, with the undo window written next to the gap between sessions, because an action whose window closed at 3 a.m. is not reversible to the person reading at 8. Jakob Nielsen's October 21, 2026 flow piece says today's AI latency is the worst you will ever suffer because chat waits are heading under a second; the agent wait is heading the other way, off the screen, and the design handbook's sixth latency band treats it as a legibility problem rather than a loading state. On falkster.com's fleet of 44 appointed agents the Monday scan and the publishing session that follows run with nobody watching, and the digest at the next session is where the three lines go.
Three lines at the next session: what it did, what it is doing, and what you can still take back, with the undo window next to the gap between sessions.
The rewrite of Nielsen's prediction, the six latency bands, and why the sixth has no second are in Nielsen's 1-Second Contract Has a Sixth Band. The Agent Ran Overnight.. The bands themselves come from Latency Is Interface, and the reversal, the notification, and the window from Undo Is a Design Primitive.
