Open Symbols - Third-Party Notices

Scope
-----

Open Symbols derives icon artwork from @hugeicons/core-free-icons version
4.1.1. The build-time conversion changes SVG primitives into path data and
adds Open Symbols layer, grouping, hierarchy and animation metadata.
The derived artwork is redistributed in @open-symbols/core's generated
catalog and individual icon exports, including their source and built forms.

The @open-symbols/react adapter uses @open-symbols/core. Its current lean
bundle contains project engine/adapter code, not the icon catalog or copied
Hugeicons artwork. React and core each carry a package-local LICENSE.
Downstream distributions that include the derived artwork should retain
this upstream notice together with the applicable license text.

Source Evidence
---------------

Installed package: @hugeicons/core-free-icons@4.1.1
Package author field: Hugeicons
Package license field: MIT
Project URL: https://hugeicons.com/
Package URL: https://www.npmjs.com/package/@hugeicons/core-free-icons/v/4.1.1
Published archive:
https://registry.npmjs.org/@hugeicons/core-free-icons/-/core-free-icons-4.1.1.tgz
Archive integrity:
sha512-teqIBvPHl90ygIwKyJwTxOH8aNp1X1PjDTcMvLkEwdPxPD+8mssrZ5kXKIAJJFYPsz69a8LYQY0UPid4PAdavg==

The installed package's README license section states:
"Created by Hugeicons. All rights reserved."

Although the package's files list names LICENSE, neither the installed
4.1.1 package nor its integrity-checked published archive contains a
LICENSE, NOTICE or COPYING file. The full upstream text reproduced below
therefore comes from Hugeicons' official repository, not from that archive.

Upstream license source, pinned rather than a moving branch:
https://github.com/hugeicons/hugeicons/blob/582ffde8c8e52a44be7b6e6779e506b58c1a3231/LICENSE.md
Upstream Git blob: df8bd19ce770b4fcf36aa581fa2a665ecad240ad
Retrieved for this packaging review: 2026-09-12

The pinned upstream file explicitly covers free icons and package source
code in that repository. Its copyright, permission, warranty and scope
text is reproduced without modification below.

Before Publication - Unresolved Review Items
-------------------------------------------

1. Version-specific upstream provenance: version 4.1.1 declares MIT, but
omits the full license file and carries the README wording quoted above.
No version-specific source commit or copyright notice was supplied in
that archive. Confirm that the reproduced upstream notice is the
appropriate notice for all copied 4.1.1 artwork before publication.
This notice does not assert that the pinned repository commit built
version 4.1.1 or resolve that provenance gap by assumption.

2. Project copyright attribution: the root, core and React manifests
already declare MIT. Their LICENSE files supply that license's standard
permission and warranty text without changing those declarations.
No project copyright holder/year was declared in the inspected source;
none has been invented or inferred from Git authorship. The project
owner must confirm the intended copyright notice before publication.
The Hugeicons copyright below applies to upstream material, not a
claim that Hugeicons authored the Open Symbols engine or adapter.

3. This review does not assess separate trademark/brand permissions,
independently establish rights ownership, or authorize publication.
Pro icon packs are not the source identified here and are not covered
by the free-package attribution. This file is a notice/provenance record,
not legal approval.
