Windshift Test Suite License 1.0

Copyright (c) 2026 the Windshift test suite copyright holders

This license applies to the tests, fixtures, assertions, expected outputs,
test-support code, and documentation in this repository (the "Test
Materials"). Windshift Core itself is licensed separately under the GNU
Affero General Public License, version 3.

1. Definitions

"Core Implementation" means software that implements all or a substantial
part of the externally observable APIs, data model, user workflows, or
behavior of Windshift Core, including a fork, rewrite, substitute, or
competing implementation.

"AGPL Implementation" means a Core Implementation for which the complete
Corresponding Source, as that term is used in the GNU Affero General Public
License version 3, is licensed under AGPL-3.0-only or AGPL-3.0-or-later and is
made available as required by that license.

"AI System" means a machine-learning model, generative model, automated coding
system, or agentic system, whether operated locally or by a third party.

2. Permission grant

Subject to this license, each copyright holder grants you a worldwide,
royalty-free, non-exclusive license to use, reproduce, inspect, modify, and
distribute the Test Materials for these purposes:

  a. testing, securing, evaluating, or contributing to Windshift Core;

  b. testing, securing, evaluating, or developing an AGPL Implementation;

  c. developing integrations, extensions, or interoperability with Windshift
     Core that do not constitute a Core Implementation; and

  d. research, education, and commentary that do not produce or improve a
     non-AGPL Core Implementation.

These permissions include using AI Systems to maintain the Test Materials,
contribute to Windshift Core, or perform the permitted activities above.

3. AI-assisted reimplementation restriction

You may not provide, expose, upload, embed, index, retrieve, prompt with, train
on, fine-tune on, benchmark against, evaluate with, or otherwise make the Test
Materials available to an AI System for the purpose of creating, completing,
improving, translating, validating, or evaluating a Core Implementation unless
that implementation is an AGPL Implementation.

You may not use the Test Materials, directly or through an AI System, to evade
the license obligations of Windshift Core or to create a Core Implementation
that is proprietary, source-available under different terms, or licensed under
terms other than AGPL-3.0-only or AGPL-3.0-or-later.

4. Redistribution and modifications

You may distribute the Test Materials or modified Test Materials only if you:

  a. provide the complete preferred form for modification;

  b. license the Test Materials under this exact license, without additional
     restrictions;

  c. preserve copyright, attribution, and license notices; and

  d. state significant modifications and their dates.

You may not relicense the Test Materials. This section does not change the
license of Windshift Core or require an independent integration to use this
license.

5. No trademark license

This license does not grant permission to use the Windshift names, logos, or
trademarks except as needed for accurate attribution or description.

6. Termination

Your rights under this license terminate automatically when you violate it.
They are reinstated provisionally when you stop the violation, and permanently
if the copyright holder does not notify you of the violation within 60 days
after you stopped it. A copyright holder may permanently reinstate rights by
written notice. Termination does not limit other remedies.

7. Disclaimer of warranty and limitation of liability

THE TEST MATERIALS ARE PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. TO THE MAXIMUM EXTENT
PERMITTED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR IS LIABLE FOR ANY CLAIM,
DAMAGES, OR OTHER LIABILITY ARISING FROM THE TEST MATERIALS OR THEIR USE.

8. Interpretation

This license does not restrict rights that do not require permission under
applicable law. If a provision is unenforceable, it shall be reformed only as
much as necessary, and the remaining provisions continue in effect. Section 3
is an express condition of the permission grant.

This is a custom source-available license. It is not the GNU Affero General
Public License and is not represented as an Open Source Initiative-approved
license.
