Local OpenAI, Anthropic, and Responses-compatible proxy that serves one Jev call per turn to answer both the model route and the thinking level for its virtual model jevonian/auto, with code filtering candidates by protocol, context window, effort floor, and spent quota windows first, and pinned models or explicit routes skipping Jev entirely.
