Jev Sandbox

An open-source, vendor-neutral web UI sandbox for /v1/systemone structured decision models such as TypeSafe Jev and Ollama clef: visualize Choice, Score and Noul probabilities, compare endpoints A/B, and export SDK calls, with a built-in mock that needs no network.

Fly.io's TypeSafeAI connector gives Sprites access to Jev without the API key entering the machine: the Sprites gateway attaches the organization's encrypted key, and each Sprite sets only TYPESAFE_BASE_URL plus a placeholder key.

Runtime supervision middleware for autonomous agents, published as andreuvm/jev-reasoning-navigator: no model-proposed action executes directly, and a deterministic runtime verifies preconditions, evaluates risk and submits actions to calibrated semantic judgment.
