      Issue

      User cacheGroups that target mf-* / remoteEntry / shared-runtime chunks can steal Module Federation runtime and shared ownership, breaking init order or duplicate-share isolation. This is an advisory for observed public splitChunks only; mfdoctor does not nag every project to set chunks: "async".

      How to fix it

      Exclude federation runtime chunks from cacheGroups (name, test, and filename). Leave MF-owned remoteEntry and shared-runtime chunks to the federation plugin, or allowlist a proven layout with allowSplitChunks: true.

      Suppress or retarget with rules["config/split-chunks-mf-runtime"] set to "off" or a severity, see Suppressions and allowlists.
