What
When the new classifier billing notice dialog is showing and the user presses Escape to decline, the tool call that triggered the notice is denied outright, with the reason recorded as "Cancelled at the classifier billing notice."
Why
This gives users a real way to stop a tool call rather than just dismissing a warning: declining the notice means the action doesn't go through.
