Remarkably, the worldsheet OPE localizes on the short-distance singularity between vertex operator insertions which in turn coincides with the OPE limit of operator insertions on the celestial sphere. The worldsheet CFT dynamically produces known celestial OPE coefficients -- as well as infinite towers of SL$(2,\\mathbb{R})$ descendant contributions to the celestial OPE -- without any truncations or approximations.
