# Third-party notices — PDF Work Helper (local candidate 0.1.0-local.1)

This product runs entirely in the browser. It ships the following third-party files unchanged
(exact list, sizes and SHA-256 in `/vendor-lock.json` of the source package). Each component keeps
its own license; the original license/notice files are shipped next to this file or next to the asset.

Not shipped: `quickjs-eval.*` and `pdf.sandbox*` (PDF scripting sandbox — scripting is not used),
the PDF.js modern build (it needs `Map.prototype.getOrInsertComputed`, missing in Chromium 141) and the PDF.js standard viewer. The UI uses system fonts only; no web fonts are shipped.

Open points (not legal advice; this list is not a full dependency legal audit):
- Which parts of `jbig2.wasm` fall under the BSD part vs the Apache part of `LICENSE_JBIG2` is not stated in the file.
- The MIT texts for base64-arraybuffer, pdfkit and core-js below are reconstructed from pdf-lib's attribution comments;
  the upstream LICENSE files are not part of the installed packages (core-js: from the copyright/license strings inside the PDF.js legacy bundle).
- The tslib license differs between the banner in the pdf-lib bundle (Apache 2.0) and the installed nested package (0BSD); both texts are shipped.
