This paper introduces a new taxonomy and resolution strategy for handling client-level disagreements in Federated Learning (FL). The proposed method creates isolated model update paths to prevent cross-contamination and unfairness, addressing scenarios where clients might exclude each other for strategic or regulatory reasons. Empirical evaluations on MNIST and N-CMAPSS datasets demonstrate the approach's effectiveness across various disagreement patterns, with negligible server-side overhead and manageable client-side costs through submodel reuse.
