## Browser-vendored libraries

| Component | Local files | Local version | Latest checked | License | Status |
| --- | --- | --- | --- | --- | --- |
| SmartyPants.js | `public/js/smartypants.js` | Header says 0.0.6 | npm `smartypants` 0.2.2 | BSD-3-Clause | Local file is not identical to npm `smartypants` 0.0.5, 0.0.9, or 0.2.2. It appears to be an older browser bundle with local or unreleased changes. |
| Hyphenopoly | `public/js/Hyphenopoly.js`, `public/js/Hyphenopoly_Loader.js`, `public/js/hyphenopoly.module.js`, `public/js/patterns/*.wasm` | Browser file header says 5.2.0-beta.1 | npm `hyphenopoly` 6.1.0 | MIT | `Hyphenopoly.js` matches the 5.2.0-beta.1 npm file after line-ending normalization. Loader differs by a small local/prototype change. Package dependency is 6.0.0, so the browser vendored copy is older than both the installed package and latest npm. |
| Knuth-Plass line breaking adapter | `public/js/knuth-and-plass.js` | No upstream version header | Unknown | Unknown/inherited prototype code | Local file differs from the prototype file and is application-adapted. Exact upstream could not be identified from file headers or npm metadata. |
| Line breaking support | `public/js/linebreak.js`, `public/js/linked-list.js` | No upstream version header | Unknown | Unknown/inherited prototype code | Files are identical to the prototype copies. Exact upstream could not be identified from file headers. |
| Kokoro JS browser bundle | `public/js/kokoro-js.js` | 1.2.0 | npm `kokoro-js` 1.2.1 | Apache-2.0 | Local file is byte-identical to `kokoro-js` 1.2.0 `dist/kokoro.web.js`; not latest. |
