+Sentinal4D ATLAS-1 – Commercial End User License Agreement (CEULA)
+Version 1.0 — © Sentinal4D Ltd. All rights reserved.
+
+Applies to: the “ATLAS-1” dataset and accompanying metadata, documentation, thumbnails, and example files (collectively, the “Dataset”).
+By downloading, accessing, or using the Dataset, you agree to this CEULA. If you do not agree, do not use the Dataset.
+
+1. Definitions
+- Dataset: All files provided by Sentinal4D under the name “ATLAS-1,” including 3D point clouds, annotations, per-point scores, metadata, previews, and documentation.
+- You / Licensee: The individual or legal entity accessing the Dataset.
+- Outputs: Predictions, visualizations, or measurements produced by models or software that were trained, tuned, evaluated, or otherwise used with the Dataset.
+- Derivative Models: Any machine learning models, embeddings, weights, checkpoints, or parameters that were trained or fine-tuned using the Dataset in whole or in part.
+- Non-Commercial Use: Academic research, teaching, personal experimentation, and publication of scientific results that do not primarily aim at commercial advantage or monetary compensation.
+- Commercial Use: Any use that is not Non-Commercial Use.
+
+2. License Grant
+Subject to this CEULA, Sentinal4D grants You a revocable, non-exclusive, non-transferable, worldwide license to:
+1) Download and use the Dataset for the Permitted Purpose (Section 3);
+2) Create Outputs;
+3) Create Derivative Models only to the extent allowed by Section 5.
+No other rights are granted. All rights not expressly granted are reserved by Sentinal4D.
+
+3. Permitted Purpose
+- Research & Education: Non-Commercial Use for academic research, method development, benchmarking, and classroom teaching.
+- Publication: Include limited excerpts (e.g., small figures, visualizations, and short video clips) in academic publications, posters, and talks with proper attribution (Section 7).
+- Evaluation: Evaluate third-party methods on the Dataset for peer-reviewed research, with results disclosed under this CEULA.
+For Commercial Use, including internal product R&D, paid services, or hosted model evaluation, You must obtain a separate commercial license from Sentinal4D (contact: legal@sentinal4d.com).
+
+4. Restrictions
+You shall not:
+- Redistribute the Dataset or substantial portions thereof, whether modified or unmodified, including re-hosting on public mirrors, torrents, or general-purpose data portals.
+- Use the Dataset or Outputs for clinical decision-making, diagnostics, medical device development, or any safety-critical application.
+- Use the Dataset to train or operate general-purpose foundation models intended for broad downstream use or commercialization (including hosted APIs) without a commercial license.
+- Use the Dataset for any program or service primarily targeting neuroscience or unrelated medical indications (field-of-use restriction; contact us for exceptions).
+- Attempt to re-identify subjects, infer confidential information, or remove provenance/attribution.
+- Use the Dataset in violation of applicable law, sanctions, export controls, or ethical guidelines.
+
+5. Derivative Models & Outputs
+- Derivative Models (Non-Commercial): You may create and use Derivative Models internally for the Permitted Purpose. You may publish papers and results and share trained weights only if the weights are released under terms no more permissive than this CEULA (i.e., they cannot enable users to reconstruct or substitute the Dataset, and they must preserve attribution and field-of-use limits).
+- Derivative Models (Commercial): Any commercial training, fine-tuning, hosting, or distribution of Derivative Models requires a separate commercial license.
+- Outputs: You may share Outputs in papers, blogs, and demos, provided they do not include substantial portions of the Dataset and include attribution.
+
+6. Security & Compliance
+You must implement reasonable technical and organizational measures to prevent unauthorized copying or redistribution of the Dataset, including access controls for internal mirrors and backups.
+
+7. Attribution
+All public use (papers, websites, demos, code releases) must include:
+“ATLAS-1 dataset © Sentinal4D (2025), used under the Sentinal4D CEULA”
+and a link to the Dataset homepage or DOI and a citation of the associated paper:
+@inproceedings{DeVries2025Interpretable,
