  • Engineer — Learn: The paper exposes a fundamental flaw in sample-and-scale DP noise protocols, achieving near-100% membership-inference success against Orchard and DP-BREM+; engineers building federated analytics or DP aggregation pipelines should audit whether their noise-sampling implementation uses the vulnerable scaling approach.
