# Third-party notices

Code under `vendor/` is copied from the projects below at the pinned commit. Each directory keeps its
upstream LICENSE/NOTICE files; those terms apply to that code. Our changes are listed as patches in `vendor/patches/`.

## Showcase on the site (Gyropup)

The home page shows [Gyropup](https://gyropup.com), a robot designed with cad-agent. Its model and pictures are
copies of Gyropup's CAD exports and results, under its MIT licence ("Copyright (c) 2026 mvalancy and Gyropup
contributors"), whose full text travels with them in `docs/img/gyropup/LICENSE.txt`.
`tools/gyropup_showcase.py` regenerates them and records the revision in each file's source record.

| Files | From | Revision |
|---|---|---|
| `web/models/gyropup.json`, `.bin`, `.webp` (the 3D model and its poster) | every part's STEP in [Valpatel/gyropup](https://github.com/Valpatel/gyropup), exported with `cad-agent view` | `77f6d00` |
| `docs/img/gyropup/wheel-link-fea.webp`, `leg-render.webp` | Gyropup's `exports/leg/fea/wheel_link-E1.png` and `exports/leg/leg-stand-iso.png`, cropped | `77f6d00` |
| `docs/img/gyropup.jpg` | a Gyropup render | earlier, not recorded |

## Runtime dependencies and external programs (not vendored)

The simulation modules and the site build use these at run time. None of their code is copied into this repository.

| Project | Licence | How cad-agent uses it |
|---|---|---|
| OpenFOAM v2512 (OpenCFD) | GPL-3.0 | External program (`cadagent.simulation.cfd` writes a case and runs it natively or in the `opencfd/openfoam-default` Docker image) |
| Bambu Studio | AGPL-3.0 | External program (`cadagent.manufacturing.slicer` runs its command line; profiles are read, flattened and passed back as files) |
| gmsh | GPL-2.0-or-later | Imported by the optional `fea` extra. Our source stays MIT; distributing a bundle that includes gmsh falls under the GPL |
| scikit-fem | BSD-3-Clause | Imported (`fea`) |
| pyMOTO | MIT | Imported (`sim`, topology optimisation) |
| PyVista, VTK | MIT, BSD-3-Clause | Imported (`sim`, pictures and animations) |
| trimesh, manifold3d, Rtree | MIT, Apache-2.0, MIT | Imported (`sim`, mesh booleans and point-in-solid tests) |
| Playwright, Chromium | Apache-2.0, BSD-3-Clause | The site build draws its Mermaid diagrams in headless Chromium through Playwright, a dev dependency (`tools/site-diagrams.mjs`); the browser tests run in it too |
| imageio, imageio-ffmpeg (FFmpeg) | BSD-2-Clause (FFmpeg LGPL/GPL binary, run as a process) | Imported (`sim`, MP4 writing) |

## Web kit (copied into project sites and published on cad-agent.valpatel.com)

`src/cadagent/webkit/vendor/` holds these files unchanged unless noted; each keeps its licence text beside it, and
`cad-agent site` copies the licence files with the code.

| Project | Licence | Version | Licence file in the kit |
|---|---|---|---|
| three.js (core and the controls, geometry, loader and utility add-ons) | MIT | r160 (npm 0.160.0); OrbitControls carries one local patch to its wheel step, recorded in `three/SOURCE.json` | header of `three/three.module.min.js`; `file-parsers/THREE-LICENSE.txt` |
| three.js STL and 3MF loaders | MIT | r160, import paths changed to the local copies | `file-parsers/THREE-LICENSE.txt` |
| fflate (the ZIP reader the 3MF loader imports) | MIT | 0.8.3, from npm | `file-parsers/FFLATE-LICENSE.txt` |
| Mermaid | MIT | 11.17.2 | `mermaid/LICENSE` |
| linkedom | ISC | 0.18.12 | `linkedom/LICENSE` |
| occt-import-js (Open CASCADE Technology compiled to WebAssembly) | LGPL-2.1 with the OCCT exception | 0.0.23 | `occt-import-js/` (four licence files; sources in `occt-import-js/source`) |
| Inter | SIL Open Font License 1.1 | 4.001, variable, Latin subset from Google Fonts (sources in `fonts/SOURCE.json`) | `fonts/OFL-Inter.txt` |
| JetBrains Mono | SIL Open Font License 1.1 | 2.211, variable, Latin subset from Google Fonts (sources in `fonts/SOURCE.json`) | `fonts/OFL-JetBrainsMono.txt` |
