Roman returned the revision to Cardinality Guardrails PR https://git.sphere.internal/data/cardinality-guardrails/pull/512 after my March blocking review. The revised fixture compares key presence in both directions and requires exact equality between each expected bounded-value set and the set observed from rollup-service. The executed regressions fail for a missing expected value, fail for an unexpected downstream value, and pass for a matching key-and-value set. Production is unchanged.
