 # cadgenbench-eval-gpu
 
-Image-only Docker Space. Provides the GPU container that the
-[CADGenBench leaderboard
-Space](https://huggingface.co/spaces/HuggingAI4Engineering/cadgenbench-leaderboard)
-pulls via `hf jobs run` to run the eval pipeline (alignment + render +
-metrics) for each submission.
+**This Space is intentionally Paused. It does not run an app.**
 
-Not intended to be run as a Gradio / web app. The `CMD ["sleep",
-"infinity"]` only exists so the Space runtime starts without
-restart-flapping after the build; pause the Space after the first
-green build to avoid idle hardware cost. The built image stays cached
-on HF and remains pullable by Jobs while paused.
+It exists only to host the GPU Docker image that the
+[CADGenBench leaderboard](https://huggingface.co/spaces/HuggingAI4Engineering/cadgenbench-leaderboard)
+pulls via `hf jobs run --image hf.co/spaces/HuggingAI4Engineering/cadgenbench-eval-gpu`
+each time a submission lands. Eval runs in a per-submission HF Job
+on `a10g-large`; this Space is just the storage backend for the
+image (the same role GHCR or Docker Hub would play in another setup).
+
+The Dockerfile + `eval_job.py` here are the entire source of truth
+for what runs inside each eval. Browsing them is supported; opening
+the live URL is not (the runtime is paused on purpose, the image is
+still cached and pullable by Jobs).
