This note explains the current repository licensing terms in plain English.
- The public repository is licensed under the Apache License 2.0.
- Apache 2.0 is a permissive open-source license: it allows use, commercial use, modification, and redistribution.
- Apache 2.0 does not require private or internal modifications to be published.
- If you redistribute the Work or Derivative Works, you must preserve the applicable license, copyright, patent, trademark, attribution, and NOTICE notices, and modified files must carry prominent notices stating that they were changed.
- Apache 2.0 includes an express patent license from contributors, subject to the license's patent-termination provisions.
- Non-trivial external contributions use a short Individual Contributor Agreement.
- If a contribution is made in the course of employment or under institutional intellectual-property rules, maintainers may also request the optional Employer / Institutional Authorization.
- The project does not require copyright assignment for normal external contributions.
- The contribution paperwork is intended to confirm submission authority and Apache 2.0 compatibility, not to create a second public licensing track.
This wording is intended for repository governance documentation and remains subject to legal validation where applicable.
