BSD 3-Clause with additional terms
SPDX-License-Identifier: LicenseRef-spaCR-BSD-3-Clause-Additional-Terms

This is a custom BSD-style license with additional noncommercial terms,
not the standard BSD 3-Clause License. The restrictions below remain
applicable to the covered material.

Copyright (c) 2025-2026, Einar Birnir Olafsson and the spaCR contributors.
All rights reserved except as expressly granted below.

1. Scope and existing rights

This license applies only to new original spaCR material first distributed
under these terms with spaCR Agreement version 4.4. It does not replace or
withdraw permissions already granted for previously BSD-licensed material,
including material incorporated in this distribution. The original BSD
3-Clause notice, conditions and disclaimer remain in LICENSE-BSD-3-Clause.
Previously released versions retain their applicable licenses and grants.
Separately licensed contributions, dependencies, datasets and model weights
remain under their own terms. No rights granted by those terms are limited
by this license. This license does not override obligations for GPL-covered
components or combined works, or authorize a distribution that violates
another applicable license. It does not certify every dependency combination
or binary distribution as compatible. Only rights the licensor has authority
to license are granted.

2. Noncommercial permission

Subject to this license, permission is granted, without a fee, to use, copy,
modify and distribute the covered material and modifications for noncommercial
purposes. Noncommercial research, education, teaching and personal experiments
are permitted. Redistributions of covered material or modifications must
include this license and its copyright notice and identify modifications.
They must not represent commercial permission as having been granted here.
Access for noncommercial research requires no account approval or material
transfer agreement. Any separately applicable third-party terms still apply.

The following BSD 3-Clause conditions also apply to redistribution of the
covered material, subject to the noncommercial scope and permissions above:

1. Redistributions of source code must retain the above copyright notice, this
   list of conditions and the following disclaimer.

2. Redistributions in binary form must reproduce the above copyright notice,
   this list of conditions and the following disclaimer in the documentation
   and/or other materials provided with the distribution.

3. Neither the name of the copyright holder nor the names of its
   contributors may be used to endorse or promote products derived from
   this software without specific prior written permission.

These conditions grant no commercial permission and do not change the
existing-rights and third-party scope in Section 1.

3. Commercial use requires separate written permission

Commercial use means use directed toward commercial advantage or monetary
compensation. It includes paid analysis or other services for third parties,
commercial hosted services, development or delivery of commercial products,
and internal research, development or operations for commercial advantage.
The purpose of the activity determines its status; academic, nonprofit,
public-sector or other organizational status alone creates no exception.
Commercial use of the covered material is not permitted without separate
written permission from an authorized licensor. Request permission at
olafsson@med.umich.com. This license grants no commercial permission and
sets no price or other terms for any separate commercial license.

4. Content, third-party rights and notices

This license does not claim ownership of users' images, measurements,
annotations, models, figures or other content. Their applicable ownership
and licenses remain unchanged. Keep all applicable third-party notices and
licenses, including rights to modify, replace, relink, obtain source,
redistribute or reverse-engineer for debugging where those terms grant them.
No trademark or endorsement rights are granted. Statutory rights that cannot
be restricted by agreement are not restricted by this license.

5. Warranty and liability

TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE COVERED MATERIAL IS PROVIDED
"AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR AND CONTRIBUTORS
ARE NOT LIABLE FOR CLAIMS, DAMAGES OR OTHER LIABILITY ARISING FROM THE
COVERED MATERIAL OR ITS USE, WHETHER IN CONTRACT, TORT OR OTHERWISE.

6. Applicable grants

Rights not expressly granted for the covered material are reserved.
A separate written commercial license governs only the rights and material
it identifies. This license is source available and is not OSI-approved.
