// Probe #421: reportPageErrors() owns a separate delivery round-trip from finish().
//
// The page error is scheduled at the tail of the browser turn and there is no
// page interaction afterwards. The verdict must therefore flush the page by
// itself. This probe deliberately never calls finish(): doing so would prove
// the older branch while leaving reportPageErrors() blind.
