Why Eval exists · why Workspace exists
Public evidence and cloud agents are the same harness.
Eval exists so scores are inspectable—tasks, trajectories, artifacts, and rubric verdicts anyone can open.Workspace exists so people can automate real file work with that harness, and so Raycaster never evaluates work it cannot perform.
