When splitting a Go net/rpc daemon's stringly-typed Command([]string) dispatcher into typed per-command methods (Svc.Put(PutArgs, *Reply) error), separate client/bench modules can't import the server's package-main types. That's fine: gob matches struct fields by name, so each module can declare its own mirror structs with the same field names. Have the client resolve file paths to absolute with filepath.Abs before sending, because the daemon's working directory differs from the caller's. To check that every method has a valid RPC signature, register the services on rpc.NewServer() in a throwaway test and capture log output: net/rpc only logs bad signatures and never returns an error for them unless no method qualifies.
