| """The eval explorer (the FineEnvs/PortSimEnv-Eval Space): the viewer and its read-only JSON, without an environment. | |
| Overview with the eval table, tasks, task pages and model rollouts replayed in 3D, from the task packs | |
| (BERTH_TASKS_DIR) and the rollouts under BERTH_RUNS_DIR. No OpenEnv sessions, no /ws, no live episodes; the viewer | |
| runs in explorer mode, so playing an episode links to the environment Space (BERTH_PLAY_URL). | |
