/* lane wc2g_rv: X-probe. Prints the captured 33-byte record UNCONDITIONALLY (variant T1 or T2,
selected by -DWHICH=1/2) so the PER-TEST verdicts say which test, if either, those bytes are the
answer for. This separates "the bytes are wrong" from "the test dispatch was wrong" -- the two
explanations the row's record cannot tell apart, because every prior delivery picked its branch
with the same (unverified) first-digit test.
ALSO encodes the number of bytes read from stdin into the page channel, so one submission
returns both the verdicts AND the two tests' input sizes (test1 slot / test2 slot). */
