A disputed answer · two parties answer one question from the same road register. Ada makes an honest mistake: 30 km, when the instrument counts 1 of 4 routes shorter. The record refuses it (COUNT_CONTRADICTS) and she corrects it to 29 km. Mallory says the register is in miles, citing the register’s own units note, which says kilometres. The record refuses it (SOURCE_CONTRADICTS), she says it again, then files it without the note. An independent reviewer reads both against the register. Nobody labels anyone: the standing below is derived on read, and so is the conduct log, which says Ada corrected what she was shown and Mallory said it again 2 times, never corrected it, and still says it.
