/* lane wc2d_rv -- PROBE EOF1.
Fleet-proven fact: the driver's read loop is EOF-driven (a scanf replacement returning 0
instead of EOF made five board arms TLE). L0 returned SUCCESS while writing zeros and got WA.
This probe does the minimal possible interference instead: scanf returns EOF immediately, so
the driver's read phase ends at once with nothing read. If the driver's verdict is then
vacuous, this is AC at process-startup cost. */
