 ## Reproducibility
 
-There are two practical reproduction paths.
+The public release supports several procedural evaluation workflows, but it is
+important to distinguish between re-running the released evaluations and
+regenerating every paper artifact from scratch.
+
+### Procedural evaluation
+
+The following public artifacts are available:
+
+- the frozen **533-sample** candidate-edge dataset and split
+- the **54** structured Procedural scene states
+- the **136-case** Procedural expanded-transfer subset
+- the paper-frozen
+  [CF-SupportNet checkpoints](https://huggingface.co/MedPhyGraph/CF-SupportNet)
+- the corresponding public MedPhyGraph evaluation code
 
-### Procedural experiments
+With these artifacts, users can re-run evaluation using the released
+candidate-edge dataset and paper-frozen CF-SupportNet checkpoints, and
+re-evaluate the public 136-case Procedural expanded-transfer subset.
 
-The released Procedural data are fully available in this repository.
+Some core procedural paper tables additionally require an intermediate file:
 
-The corresponding paper-frozen model checkpoints are available from:
+```text
+outputs/dyphygraph_health/dataset_twinworld_phase2/dataset.json
+```
+
+That intermediate dataset is **not included directly** in this Hugging Face
+release.
 
-[**MedPhyGraph/CF-SupportNet**](https://huggingface.co/MedPhyGraph/CF-SupportNet)
+The corresponding structured Phase-2 procedural scenes are included under
+`procedural_scenes/`, and the public MedPhyGraph code contains the
+data-generation components needed for this workflow.
 
-Together with the public MedPhyGraph project artifacts, these files support
-end-to-end reproduction of the released Procedural experiments.
+For this reason, this repository should be understood as the frozen public data
+release supporting the Procedural evaluation workflows, rather than as a
+one-command reproduction package for every paper table.
