# DBbun DARPA Lift Challenge R&D License v1.1 **Effective Date:** June 22, 2026 **Copyright (c) 2025–2026 DBbun LLC. All rights reserved.** This license governs the use of synthetic datasets, time-series records, design metadata, documentation, reports, figures, dashboards, and generative simulation code made available by DBbun LLC for DARPA Lift Challenge-related research and development (collectively, the “Licensed Materials”). The Licensed Materials are provided under a custom, non-open-source, non-transferable research and development license. By accessing, downloading, copying, running, modifying, or using the Licensed Materials, the user accepts the terms of this license. “Licensee” means any individual, team, company, academic institution, government entity, contractor, evaluator, or other organization that accesses, downloads, copies, runs, modifies, or uses the Licensed Materials. --- ## Official Source The official DBbun-controlled access points for the Licensed Materials are: - Hugging Face repository: https://huggingface.co/datasets/DBbun/DARPA_Lift_2026 - GitHub repository: https://github.com/DBbun/dbbun-darpa-lift - GitHub dashboard repository: https://github.com/DBbun/dbbun-darpa-lift-dashboard - DBbun website: https://dbbun.com/ - Contact: contact@dbbun.com Hosting the Licensed Materials on Hugging Face, GitHub, or other repositories controlled by DBbun LLC does not grant any right to redistribute, mirror, sublicense, re-upload, or publish the Licensed Materials elsewhere. --- ## Licensed Use The Licensee may use, modify, and run the Licensed Materials solely for internal research and development related to participation in the DARPA Lift Challenge, including: - mission design and modeling; - evaluation and internal R&D; - training, testing, and optimization for autonomous systems; - preparation of submissions to the DARPA Lift Challenge; and - private internal derivative materials for competition-related use. All derivative works, modified datasets, model outputs, reports, simulations, dashboards, or executable variants based on the Licensed Materials must remain private unless DBbun LLC provides express written permission. --- ## Prohibited Actions Without express written permission from DBbun LLC, the Licensee may not: - redistribute, publish, disclose, mirror, re-upload, or make the Licensed Materials publicly available outside the Licensee’s organization; - use the Licensed Materials in any commercial product or service; - sell, sublicense, lease, transfer, assign, or provide the Licensed Materials or derivative works to any third party; - use the Licensed Materials for operational deployment, procurement, production systems, commercial services, or broader government-purpose use; - upload, transmit, or provide the Licensed Materials to public repositories, public model hubs, external AI systems, or third-party cloud services in a manner that permits third-party retention, training, redistribution, or use beyond private internal DARPA Lift Challenge R&D; - remove or alter copyright, attribution, provenance, license, or disclaimer notices; or - continue using the Licensed Materials after termination of this license, except as expressly permitted under the Academic Research Exception. This license is non-transferable. Rights granted under this license may not be assigned, shared, sublicensed, or transferred to any third party. --- ## Academic Research Exception Universities and accredited academic institutions may use the Licensed Materials for non-commercial research and education purposes, including coursework, master’s theses, doctoral dissertations, and scholarly publications, provided that: - DBbun LLC is cited in all resulting works; - the Licensed Materials are not redistributed, mirrored, re-uploaded, or made publicly downloadable by the academic institution or its researchers; - derived datasets, modified datasets, model outputs, reports, simulations, dashboards, or executable variants remain private unless separately authorized by DBbun LLC; and - all commercial rights remain exclusively owned by DBbun LLC. Academic use expressly permitted under this Academic Research Exception may continue after conclusion of the DARPA Lift Challenge, provided that all conditions of the Academic Research Exception continue to be satisfied. Academic users may publish scholarly analysis, results, conclusions, figures, and citations based on use of the Licensed Materials, but may not publish or redistribute the Licensed Materials themselves, substantial portions of the datasets, source code, executable variants, or derived datasets without express written permission from DBbun LLC.

Continued use, retention, evaluation, benchmarking, model training, internal R&D, commercial use, government-purpose use, operational use, procurement-related use, use in future competitions, or use in any product or service after the DARPA Lift Challenge concludes requires a separate written agreement with DBbun LLC. No continued use is permitted merely because the Licensed Materials were previously downloaded from a DBbun-controlled repository. For broader licensing, commercial applications, procurement, government-purpose use, or post-challenge use, contact DBbun LLC at contact@dbbun.com. --- ## Intellectual Property All rights, title, and interest in the Licensed Materials are and remain exclusively owned by DBbun LLC. No patent, trademark, copyright, trade secret, database right, or other intellectual property right is transferred by this license. The generative simulation design, methodology, organization, software structure, documentation, datasets, reports, figures, and associated materials are proprietary innovations of DBbun LLC. --- ## Government Rights Use by the U.S. Government is limited to evaluation and administration of the DARPA Lift Challenge unless otherwise agreed in writing by DBbun LLC. Any broader government purpose, including commercialization, procurement, operational deployment, production use, benchmarking outside the DARPA Lift Challenge evaluation context, or distribution outside the DARPA Lift Challenge evaluation context, requires a separate written agreement with DBbun LLC. No rights are granted under this license under the Federal Acquisition Regulation, Defense Federal Acquisition Regulation Supplement, or other government data-rights regimes except to the extent expressly agreed in writing by DBbun LLC. --- ## Attribution and Notices The Licensee must preserve all copyright, attribution, provenance, license, and disclaimer notices included with the Licensed Materials. Any permitted citation, discussion, academic publication, internal report, or challenge-related submission that references the Licensed Materials should identify DBbun LLC as the source of the Licensed Materials. --- ## Warranty Disclaimer THE LICENSED MATERIALS ARE PROVIDED “AS IS,” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS, RELIABILITY, OR FITNESS FOR ANY OPERATIONAL, SAFETY-CRITICAL, PROCUREMENT, OR GOVERNMENT-PURPOSE USE.

Upon termination, the Licensee must cease using the Licensed Materials and must irreversibly delete or destroy all Licensed Materials and unauthorized derivative works in its possession or control, including local, cached, cloud, and backup copies to the extent technically feasible in the ordinary course.
