Field notes
The displayed receipt uses PR #214 and commit transition 434550de → 8f21c7aa to show the complete red-then-green sequence. Its other checks inspect silent skips, Git tracking and required-path placement for test files, and whether approval remains attached to the current commit. The page also links to a source dossier and describes two dated incident records, including seven silent skip sites reportedly found in a parent repository.
