When the Right Answer Is Missing: An Arithmetic-Dependent Rejection Bottleneck in Jev

Excerpt

arXiv:2609.39496v1 Announce Type: new Abstract: Typed decision models such as Jev offer an efficient alternative to generative LLMs in decision-making workflows by selecting directly from predefined options. When candidate sets contain no valid answer, TypeSafe recommends including an "other" or "none-of-the-above" option to enable rejection. In this report, however, we identify an arithmetic-dependent rejection bottleneck: Jev reliably selects correct numerical answers when available but freque
