Validates Pivot pipeline fingerprinting by identifying code changes that bypass cache invalidation logic.
This skill provides a structured framework for stress-testing the Pivot build system's fingerprinting accuracy. It helps developers hunt for 'stale cache' bugs by identifying edge cases—such as primitive collections in closures or deep transitive dependencies—where code modifications change runtime output but fail to trigger a stage re-run. By following a rigorous workflow for logging attempts and deduplicating root causes, it ensures that production pipelines remain reliable and that the Change Detection Matrix accurately reflects real-world behavior.
