New Assistant

Jev-only assistant test page for site admins

Added an admin page that runs the Dashboard assistant with TypeSafe Jev making every decision and no OpenAI requests.

Site admins can open Jev assistant from the Assistant row in Admin. It shows the same assistant panel as Dashboard with its own conversation. Jev chooses each operation, fills its arguments by choosing from phrases in the request, earlier results, and dates around today, and decides when the request is finished. Replies are written from the saved results. Runs use the same tools, permissions, saved results, and write checks as the Dashboard assistant, and writes change real records.

Jev cannot write new text, so requests that need drafted content, such as a document body the user did not supply, are not completed. The page requires TYPESAFE_API_KEY. The provider comparison command can now include this Jev-only candidate alongside the OpenAI assistant. The Dashboard assistant is unchanged.
