We had five repos and the same source value living in five places. Every pipeline was green because each repo was right by its own local standards. Change a value and the basis written next to it in one pull request, and every guard in that repo stays green.
Nothing in the code was broken. The denominator was.
A doc points at a file somebody moved. A token changes in one repo and the four that copied it keep the old value. Every guard stays green, because nothing was watching.
graduand reads the rules your repo declares and judges whether they still hold at this commit — doc links, shared values, UI paths. Three answers: pass, violation, unjudged. Never a score. A cell nobody read is never a pass.
For teams with more than one repo. Runs in your CI or the browser. Your code never reaches us.
