A local, open, Jev-compatible "System One" decision model. s1-jev-cvltist is the name of this release model (project codename "system one", s1; the internal checkpoint id is s1-v6).

It is deliberately built on a general instruction base (Qwen3.5-4B) with a thin LoRA adapter, so it carries knowledge a purpose-built encoder can't, while the readout…
