# kageos Contributor License Agreement Version 1.0 · Effective 2026-08-18 Thank you for contributing to kageos. This Contributor License Agreement (`Agreement`) clarifies the intellectual-property rights granted with contributions while allowing contributors to keep ownership of their work. This Agreement is between you (`You`) and 北京恰研智能科技有限公司 (`Company`). It covers Contributions that You intentionally submit to the [`kageos/kageos`](https://github.com/kageos/kageos) repository (`Project`), whether submitted before or after You accept this Agreement. If You accept this Agreement on behalf of a legal entity, You represent that You have authority to bind that entity. In that case, `You` means that entity and its controlled affiliates. If Your employer or another party owns rights in a Contribution, You must obtain its permission before submitting it. ## 1. Definitions `Contribution` means any original work of authorship, modification, addition, documentation, design, test, or other material intentionally submitted by You for inclusion in the Project. Submission includes a pull request, commit, patch, or other communication clearly intended for inclusion. Material that You conspicuously mark as `Not a Contribution` is excluded. `control` means the power to direct an entity's management or policies, or ownership of more than fifty percent of its voting interests. ## 2. Ownership You retain all right, title, and interest in Your Contributions, subject only to the licenses granted in this Agreement. You remain free to use and license Your Contributions for any other purpose. ## 3. Copyright license You grant the Company and its affiliates a perpetual, worldwide, non-exclusive, royalty-free, fully paid, irrevocable, transferable, and sublicensable copyright license to reproduce, modify, prepare derivative works of, publicly display, publicly perform, make available, use, offer for sale, sell, import, distribute, and otherwise exploit Your Contributions, in source or object form. This grant includes the right to license and relicense Your Contributions as part of the Project under any terms the Company chooses, including current or future open-source, source-available, proprietary, and commercial license terms. It also includes the right to exercise these permissions through the Company's affiliates, distributors, service providers, partners, and customers. Other than rights of attribution that cannot be waived, and to the extent permitted by law, You waive and agree not to assert moral rights or similar rights in Your Contributions that would interfere with these permissions. This does not transfer ownership of Your Contributions to the Company. ## 4. Patent license You grant the Company, recipients of the Project, and their respective affiliates a perpetual, worldwide, non-exclusive, royalty-free, fully paid, irrevocable patent license to make, have made, use, offer for sale, sell, import, and otherwise transfer the Project. This license applies only to patent claims that You can license and that are necessarily infringed by Your Contribution alone or by its combination with the Project at the time of submission. If You or an entity You control initiates patent litigation alleging that the Project or a Contribution infringes a patent, the patent licenses granted by You under this section terminate as of the filing date of that litigation. ## 5. Your representations You represent that: 1. You are legally entitled to grant the rights in this Agreement. 2. Each Contribution is Your original work, or You have clearly identified all third-party material and its license in the submission. 3. If Your employer or another party may own or control relevant rights, You have received permission sufficient to make the Contribution and grant these licenses. 4. To Your knowledge, the Contribution does not contain confidential information, credentials, personal data, malicious code, or material that You are not authorized to disclose. 5. You will promptly notify the Company if any of these statements becomes inaccurate for a submitted Contribution. ## 6. No obligation, support, or warranty The Company is not required to accept, use, or continue distributing any Contribution. You are not required to provide support for a Contribution. Unless separately agreed in writing and to the extent permitted by law, each Contribution is provided `AS IS`, without warranties or conditions of any kind, and You are not liable for damages arising solely from the Company's or a recipient's use of the Contribution. ## 7. Electronic acceptance and duration You may accept this Agreement electronically by opening or updating a pull request and checking the CLA acknowledgement included in the Project's pull request template. The Project records the accepting GitHub account, pull request, commit history, Agreement version, and acceptance time as evidence of acceptance. The Company may require a separately signed document when the authority of an individual or corporate contributor needs additional verification. You may stop making future Contributions at any time. The licenses already granted for submitted Contributions are irrevocable. A later version of this Agreement applies only after You accept that later version. ## 8. General terms This Agreement is the complete agreement concerning Contributions to the Project and supersedes prior contribution terms on the same subject. A waiver or amendment must be in writing. If any provision is unenforceable, it will be adjusted only as necessary, and the remaining provisions will continue in effect. This Agreement is governed by the laws of the People's Republic of China, without regard to conflict-of-law rules. Disputes are subject to the jurisdiction of the competent people's court at the Company's domicile. The Chinese version in [`CONTRIBUTOR_LICENSE_AGREEMENT.zh-CN.md`](CONTRIBUTOR_LICENSE_AGREEMENT.zh-CN.md) and this English version are intended to describe the same agreement. If they conflict, the Chinese version controls.
