      Issue

      A React host that loads remotes without sharing its imported React runtime can create separate React or renderer instances across the federation graph.

      How to fix it

      Declare imported react and react-dom packages as singleton shared dependencies, for example { singleton: true }, or suppress the rule when the separate runtime is intentional.

      Suppress or retarget with rules["shared/react-host-missing"] set to "off" or a severity — see Suppressions and allowlists.
