Fathomrow is the night audit of a river counting-house. Twenty clerks stay after the lamps are turned down. Some keep the books. Some forge a line. You are not told which. You only get the sentence they left.
The rule is small on purpose. An innocent clerk's sentence is true. A guilty clerk's sentence is false. From that rule, and from twenty sentences, one verdict fits.
A new bench is posted each UTC day. Older benches stay in the archive. Practice benches are separate. Nothing here is sold, and the pages do not load third-party scripts, fonts, or trackers.
