Package fixture produces fixture pairs (left/right) with known planted differences, in every supported format, plus a manifest.json of the ground truth.

Package output renders diff results for humans and machines.

Package schema computes schema diffs between two sources and decides which columns are comparable for the row diff.

Package source defines the format-agnostic Source interface consumed by the diff engine, plus readers for each supported file format.
