# PufferPDF browser PDF runtime

This directory contains the reviewed browser runtime used by PufferPDF. Its
exact upstream origin, pinned commit, PufferPDF fidelity patch, and required
attribution are recorded in the root `THIRD_PARTY_NOTICES.txt` and the vendor
source record it references.

Runtime version: `0.1.3-pufferpdf.1`.

The reviewed patch retains validated HTTP, HTTPS, and mailto link annotations
as Markdown links while leaving unsafe or ambiguous annotations as plain text.

The release package includes the corresponding source patch, exact toolchain,
artifact checksums, and self-contained rebuild instructions described in the
[third-party notice](../../../THIRD_PARTY_NOTICES.txt). The runtime never
downloads parser code from the upstream repository or a CDN.

The upstream code and the PufferPDF patch are distributed under the licenses
recorded in the notice files. `LICENSE` also retains the Adobe CMap third-party
notice required by the embedded resources. `THIRD_PARTY_LICENSES.txt` records
the exact locked Cargo dependency inventory and its bundled license texts.
