Question 260
Another application rebuilds an unchanged commit but resolves a different transitive version on a clean runner. Which unsupported assumption should the engineer challenge FIRST?
Explanation
Correct Answer
An unchanged source commit does not guarantee an unchanged artifact when dependency resolution floats. This is the relevant unsupported assumption because build reproducibility depends on stable dependency resolution, not just a fixed application commit.
Incorrect Answers
This caution is valid in design and implement a testing strategy for pipelines, but it is not the failure assumption illustrated by this scenario. The directly relevant risk is: An unchanged source commit does not guarantee an unchanged artifact when dependency resolution floats.
