How is causality encoded in string theory?

There is a superficially similar thread, Causality in String Theory, which however asks a quite different question.

  • $\begingroup$ Just like it's encoded in the standard model: the theory respects Poincaré symmetry (the symmetry group of special relativity). $\endgroup$ – Kibble Jan 12 '17 at 20:23

    $\begingroup$ But Poincare symmetry is not enough for causality in quantum field theory. One needs local commutation rules for the fields. What is the equivalent of that in string theory? $\endgroup$ – Arnold Neumaier Jan 12 '17 at 20:32

    $\begingroup$ You are aware of this thesis ? etheses.dur.ac.uk/3028 ? ( way over my head :) ) $\endgroup$ – anna v Jan 13 '17 at 7:41
