Task: TCP guessing game that leaks the 0-indexed position of the first mismatching character of a secret base64 string built from a random hex token, the client IP, and a live UTC timestamp. Solution: abuse the position oracle to recover the secret character-by-character with predicted candidates, then replay the exact recovered string instead of recomputing the time-dependent value (which drifts at the seconds field).
