 # Third-Party Notices
 
-This project redistributes the following third-party components.
+Nucleus itself is distributed under the MIT license (see [`LICENSE`](LICENSE)). This file lists

+or as binaries inside a published artifact — together with their licenses and where the full
+license text lives.

+
+The Nucleus Gradle plugin (`plugin-build/plugin`) is a **derivative work** of the JetBrains Compose
+Multiplatform Gradle plugin (`org.jetbrains.compose.desktop.application`). 127 Kotlin files under
+`plugin-build/plugin/src/` retain their original copyright header, for example:

+## 2. tao — vendored source, compiled into a shipped binary (Apache-2.0)
+
+`decorated-window-tao` vendors a patched fork of the Rust `tao` crate at
+`decorated-window-tao/src/main/native/vendor/tao/`, redirected via `[patch.crates-io]`. It is
+compiled into `libnucleus_tao.{dylib,so,dll}`, which ships inside the
+`nucleus.decorated-window-tao` JAR.
+
+- Project: tao — https://github.com/tauri-apps/tao

+  `decorated-window-tao/src/main/native/vendor/tao-patches/README.md`

+
+## 3. AccessKit — vendored source, compiled into a shipped binary (MIT OR Apache-2.0)
+
+Three AccessKit crates are vendored and patched to project the accessibility tree to AT-SPI
+(Linux) and UI Automation (Windows). Each divergence from upstream is documented in the crate's
+`VENDORED.md`.
+
+| Crate | Version | Path |

+## 4. ANGLE (libEGL.dll, libGLESv2.dll) — shipped binary (BSD 3-Clause)
+
+The Tao Windows backend (`decorated-window-tao`) ships the ANGLE runtime libraries `libEGL.dll` and
+`libGLESv2.dll` to provide a Direct3D 11 render path (OpenGL ES translated to D3D11, with a WARP
+software fallback for RDP / VM / driverless environments).

+- **electron-builder** 26.15.5 (MIT) — packaging backend for 17 of the 18 target formats. The
+  plugin embeds only a pinned `package.json` / `package-lock.json` pair
+  (`plugin-build/plugin/src/main/resources/nucleus/electron-builder/`) and installs the tree with
+  `npm ci --ignore-scripts` into a build-local directory. See
+  `scripts/update-electron-builder-lock.sh`.
+- **GraalVM** (GraalVM CE: GPLv2 with Classpath Exception; Oracle GraalVM: GFTC) — downloaded on
+  demand when `graalvm { isEnabled = true }`. Selecting `GraalvmDistribution.ORACLE` makes the
+  plugin emit a licensing warning, because the GFTC restricts charging a fee in connection with
+  redistributing the program.
+
+## Transitive Rust crates
+
+`libnucleus_tao` statically links the full Rust dependency tree of the `nucleus_tao` crate (`jni`,
+`once_cell`, the `gtk-rs` stack, `zbus`, `windows`, `x11-dl`, …), which is permissively licensed
+(predominantly MIT and Apache-2.0). The authoritative, version-exact list is
+`decorated-window-tao/src/main/native/Cargo.lock`; regenerate a per-crate license inventory with
+`cargo license` or `cargo about` from `decorated-window-tao/src/main/native/`. Sections 2 and 3
+above cover the crates Nucleus has forked and therefore redistributes as source.

+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses

+       distribution, then any Derivative Works that You distribute must
+       include a readable copy of the attribution notices contained
+       within such NOTICE file, excluding those notices that do not
+       pertain to any part of the Derivative Works, in at least one
+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside

+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with

+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.

+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.
