# Third-party notices

## Anthropic Jacobian lens

The `jlens` package and reference slice renderer derive from Anthropic PBC's
`anthropics/jacobian-lens` reference implementation at commit
`581d398613e5602a5af361e1c34d3a92ea82ba8e`. Those files are licensed under
Apache License 2.0 and retain their original notices.

The distributed reference pages retain this notice:

Copyright 2026 Anthropic PBC

SPDX-License-Identifier: Apache-2.0

The Apache License 2.0 text is in `LICENSE` and is copied to
`licenses/APACHE-2.0.txt` in the Pages build.

## D3

The self-contained reference slice pages embed D3 7.9.0. Its ISC license is in
`LICENSES/D3-ISC.txt` and is copied into the Pages build.

## Fonts

The site bundles EB Garamond and JetBrains Mono. Their SIL Open Font License
texts are in `LICENSES/` and beside the webfont files in `site/assets/fonts/`.

## VibeThinker and Qwen

The lens is fitted for `WeiboAI/VibeThinker-3B`. That model identifies
`Qwen/Qwen2.5-Coder-3B` as its base. The companion model and trace repositories
use the Qwen Research License as the conservative distribution policy. The
full Qwen terms are in `LICENSES/QWEN-RESEARCH.txt`. The pinned VibeThinker
model card metadata declares `license: mit`, but the pinned repository tree
contains no `LICENSE` or `NOTICE` file. The source record is in
`LICENSES/VIBETHINKER-LICENSE-NOTE.txt`. The Pages build includes both the Qwen
terms and the VibeThinker license note. This source repository does not contain
either model's weights.
