Progressive delivery fails quietly when exposure events fire on deploy rather than on the variant UI, or when cohort buckets disagree between feature flags and analytics. We audit assignment, exposure logging, and how percentage rollouts land in your warehouse.
The audit covers one primary rollout path and one secondary surface. Limitations — sample size, bot traffic, known flag lag — go in the appendix so leadership does not treat a thin canary as a full proof.
Useful before a high-visibility launch, after a contested canary, or when flag tooling changed and historical comparisons broke.
Includes
