Field notes
The workflow requires users to identify the passing and failing runs themselves rather than guessing from exit status. Its normalization is deliberately narrow: leading ISO timestamps and workspace prefixes can be removed, while ports, durations, versions, and other numbers remain visible. The page also describes bounded alignment, inert log rendering, and exports that omit text unless selected, making its operating boundaries part of the product.
