MetaHz / MetaClaw — Dual License
Copyright (C) 2026 Baicheng Chen. All rights reserved.

Effective for new MetaHz-owned releases designated under these terms on or
after September 17, 2026.

Choose one of these licensing paths:

1. MetaHz Community License 1.0: free for personal, noncommercial use by an
   individual, subject to the terms below.
2. Education or commercial license: contact xyzhang@ucsd.edu and obtain a
   separate written agreement before educational, institutional or commercial
   use. An inquiry alone is not a license.

METAHZ COMMUNITY LICENSE 1.0

1. Scope

"Software" means the MetaHz-owned source code, software and accompanying
documentation expressly distributed under this license. "Licensor" means
the holder of the applicable copyright. This license grants rights only to
material the Licensor owns or is authorized to license under these terms.

Third-party components, dependencies, data, models, papers, assets and other
separately licensed material are excluded. Their own notices and licenses
continue to apply. No rights to those materials are expanded or restricted
by this license. Where material carries a different applicable license, that
license governs that material.

2. Free personal-use grant

Subject to these terms, the Licensor grants you, as an individual, a worldwide,
nonexclusive, royalty-free right to use, reproduce and modify the Software
solely for your own private, noncommercial personal or hobby projects.

You may share copies of the Software or your modifications without charge
with other individuals for use within this same grant. You must include this
license and preserve copyright, attribution and third-party notices. Mark
modified versions clearly. Recipients receive their rights directly from the
Licensor under this license; you may not grant broader rights to the Software.

3. Uses requiring a separate agreement

The Community License does not authorize:

- Education, teaching, coursework, training programs, academic research, or
  use by or on behalf of a school, university, laboratory or other institution.
- Any business, employment, professional, consulting or commercial activity,
  including internal business operations and research and development.
- Offering the Software as a product, hosted service or part of a paid or
  monetized offering, or using it to provide services to another person or
  organization for compensation.

Contact xyzhang@ucsd.edu for an education or commercial license covering your
intended use. Rights, fees, support and deployment scope are established only
by that separate written agreement. Free access does not by itself authorize
uses outside the Community License.

4. Notices and reserved rights

Do not remove or obscure copyright, license or attribution notices. You may
not represent a modified version as an official MetaHz release or use MetaHz
names or marks to imply endorsement. This license grants no trademark rights,
rights to third-party services, or licenses for external simulation software.
All rights not expressly granted are reserved. Your original work and results
remain yours; using the Software does not transfer their ownership to MetaHz.
Their creation and use must still comply with the applicable licensing path.

5. No warranty

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND
NONINFRINGEMENT. YOU ARE RESPONSIBLE FOR CHECKING RESULTS AND SUITABILITY FOR
YOUR USE. NO SIMULATION OUTPUT IS A WARRANTY OF PHYSICAL OR FABRICATION
PERFORMANCE.

6. Limitation of liability

TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR AND CONTRIBUTORS WILL
NOT BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY ARISING FROM OR IN
CONNECTION WITH THE SOFTWARE OR ITS USE, WHETHER IN CONTRACT, TORT OR OTHERWISE.
THIS DOES NOT EXCLUDE LIABILITY OR RIGHTS THAT APPLICABLE LAW DOES NOT ALLOW
TO BE EXCLUDED.

7. Termination

Your rights under this license terminate if you use the Software outside its
grant or otherwise breach these terms. You must stop the unauthorized use and
distribution. A separate license agreement may authorize continued use.
Termination does not alter the rights of recipients who remain in compliance.

8. Earlier releases and other agreements

These terms apply prospectively to releases expressly designated under this
license. They do not revoke rights already granted for copies obtained under
an earlier license, including the GPL. The prior repository notice is retained
in docs/legal/prior-gpl-notice.txt for historical reference; the license supplied
with the particular earlier release determines its terms.

If you have a separate signed education or commercial agreement with the
Licensor, that agreement controls your use within its stated scope. The website
license page is a summary; this text or your applicable written agreement
governs if a summary differs.
