EpiphanyAgent Repository License Notice
=======================================
This repository is a multi-license distribution. Different parts of the
repository are available under different terms.
Nothing in this file narrows, revokes, or relabels rights already granted by
upstream licenses. In particular, nothing in this file should be read as
withdrawing any permission granted by Apache License 2.0 for Apache-covered
material.
1. Scope
--------
For this file:
- `Project-Authored Material` means original software, documentation, and other
repository content authored for EpiphanyAgent, except where a file or
directory states different terms.
- `Upstream Material` means material copied or adapted from third parties and
distributed under their own licenses.
2. Upstream And Third-Party Material
------------------------------------
- Other third-party material distributed with the repository keeps its own
license terms where provided.
- You must continue to comply with those upstream terms when using,
redistributing, or modifying upstream material.
3. Public License For Project-Authored Material
-----------------------------------------------
Except where a file or directory says otherwise, Project-Authored Material is
licensed to the public under:
- PolyForm Noncommercial License 1.0.0
The full text of that license appears in Appendix A of this file.
Required Notice: Copyright 2026 EpiphanyAgent authors and contributors.
4. Commercial License Option
----------------------------
If you want to use Project-Authored Material for any purpose not permitted by
PolyForm Noncommercial License 1.0.0, you must obtain a separate written
commercial license from the applicable copyright holder or another party
expressly authorized in writing to grant that license.
Commercial rights are not granted by:
- source availability
- public access to this repository
- silence
- estoppel by implication
- the fact that the licensors are not yet organized as a corporation or LLC
A natural person can own and license copyright. Until a separate business
entity is formed and designated in writing, any commercial license for
Project-Authored Material may be offered directly by the individual copyright
holder or holders.
5. Open Source Status
---------------------
Because the public license path for Project-Authored Material is PolyForm
Noncommercial License 1.0.0 rather than an OSI-approved license, the
repository as a whole is source-available and dual-licensed. It is not an OSI
Open Source distribution as a whole.
6. Reference Structures
-----------------------
This licensing structure intentionally borrows the general dual-license shape
used by established projects such as Qt and MySQL:
- one public-facing license path
- one separate commercial license path
This repository does not claim that Qt or MySQL use the same exact public
license terms used here. Those projects are referenced only as structural
examples of dual licensing, not as the operative terms of this repository.
7. Contributions
----------------
External contributions are accepted only under the EpiphanyAgent Contributor
License Agreement in `CONTRIBUTOR_LICENSE_AGREEMENT.md`, or under a separate
written agreement accepted by the Project Steward.
The contributor agreement is intentionally broad. Contributors keep ownership
of their contributions, but grant the Project Steward the right to sublicense
and relicense those contributions under any license or terms the Project
Steward chooses, including commercial or proprietary terms.
The project should not accept non-trivial outside contributions unless the
contributor has agreed to that contributor agreement or an equivalent written
agreement.
Appendix A: PolyForm Noncommercial License 1.0.0
------------------------------------------------
The following text is included as the operative public license for
Project-Authored Material described in Section 3.
# PolyForm Noncommercial License 1.0.0
<https://polyformproject.org/licenses/noncommercial/1.0.0>
## Acceptance
In order to get any license under these terms, you must agree
to them as both strict obligations and conditions to all
your licenses.
## Copyright License
The licensor grants you a copyright license for the
software to do everything you might do with the software
that would otherwise infringe the licensor's copyright
in it for any permitted purpose. However, you may
only distribute the software according to Distribution
License and make changes or new works based on the software
according to Changes and New Works License.
## Distribution License
The licensor grants you an additional copyright license
to distribute copies of the software. Your license
to distribute covers distributing the software with
changes and new works permitted by Changes and New Works
License.
## Notices
You must ensure that anyone who gets a copy of any part of
the software from you also gets a copy of these terms or the
URL for them above, as well as copies of any plain-text lines
beginning with `Required Notice:` that the licensor provided
with the software. For example:
> Required Notice: Copyright Yoyodyne, Inc. (http://example.com)
## Changes and New Works License
The licensor grants you an additional copyright license to
make changes and new works based on the software for any
permitted purpose.
## Patent License
The licensor grants you a patent license for the software that
covers patent claims the licensor can license, or becomes able
to license, that you would infringe by using the software.
## Noncommercial Purposes
Any noncommercial purpose is a permitted purpose.
## Personal Uses
Personal use for research, experiment, and testing for
the benefit of public knowledge, personal study, private
entertainment, hobby projects, amateur pursuits, or religious
observance, without any anticipated commercial application,
is use for a permitted purpose.
## Noncommercial Organizations
Use by any charitable organization, educational institution,
public research organization, public safety or health
organization, environmental protection organization,
or government institution is use for a permitted purpose
regardless of the source of funding or obligations resulting
from the funding.
## Fair Use
You may have "fair use" rights for the software under the
law. These terms do not limit them.
## No Other Rights
These terms do not allow you to sublicense or transfer any of
your licenses to anyone else, or prevent the licensor from
granting licenses to anyone else. These terms do not imply
any other licenses.
## Patent Defense
If you make any written claim that the software infringes or
contributes to infringement of any patent, your patent license
for the software granted under these terms ends immediately. If
your company makes such a claim, your patent license ends
immediately for work on behalf of your company.
## Violations
The first time you are notified in writing that you have
violated any of these terms, or done anything with the software
not covered by your licenses, your licenses can nonetheless
continue if you come into full compliance with these terms,
and take practical steps to correct past violations, within
32 days of receiving notice. Otherwise, all your licenses
end immediately.
## No Liability
As far as the law allows, the software comes as is, without
any warranty or condition, and the licensor will not be liable
to you for any damages arising out of these terms or the use
or nature of the software, under any kind of legal claim.
## Definitions
The licensor is the individual or entity offering these
terms, and the software is the software the licensor makes
available under these terms.
You refers to the individual or entity agreeing to these
terms.
Your company is any legal entity, sole proprietorship,
or other kind of organization that you work for, plus all
organizations that have control over, are under the control of,
or are under common control with that organization. Control
means ownership of substantially all the assets of an entity,
or the power to direct its management and policies by vote,
contract, or otherwise. Control can be direct or indirect.
Your licenses are all the licenses granted to you for the
software under these terms.
Use means anything you do with the software requiring one
of your licenses.
