The MIT OR Apache-2.0 SOURCE license is clean (audit found no copied copyleft); the
gaps were all binary-distribution (Layer-2). This makes the shipped artifacts honest:
- Windows host + client: bundled FFmpeg BtbN gpl-shared -> lgpl-shared (AMF/QSV/decode
unaffected; the GPL-only x264/x265 were never used), and ship the FFmpeg LGPL notice
+ license text in the installer + MSIX (licenses/).
- THIRD-PARTY-NOTICES.txt generated + bundled into installer/MSIX/deb/rpm. Offline
generator (scripts/gen-third-party-notices.{py,sh}) + cargo-about config (about.toml/
.hbs) with a permissive-only accepted-license allow-list as a copyleft regression gate.
- Reword the win32u GPU-preference hook comments to reflect independent reimplementation
(no Apollo/Sunshine GPL-3.0 source copied).
- README dual-license + inbound=outbound contributor clause + non-affiliation trademark
disclaimer; new CONTRIBUTING.md.
- LICENSE files into the standalone driver + vk-layer workspaces; deb copyright holder
aligned to "unom and the punktfunk contributors".

Licensing of contributions (inbound = outbound)
punktfunk is dual-licensed under MIT OR Apache-2.0.
Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as MIT OR Apache-2.0, without any additional terms or conditions.
By opening a pull request you agree to license your contribution under these terms. This is the standard Rust-ecosystem "inbound = outbound" model; it keeps the project's licensing unambiguous (including the Apache-2.0 §5 contributor patent grant) and any future relicensing clean. You retain the copyright to your contributions.
Do not paste copyleft (or otherwise incompatibly-licensed) code
The single thing that could poison the permissive license is copied source from a copyleft project. Several adjacent projects (Sunshine, Apollo, Moonlight) are GPL-3.0. You may study them and reimplement a technique, protocol, or wire format — those are not copyrightable — but never paste their code, and do not translate a GPL implementation line-by-line. When a comment credits prior art, make clear it is an independent reimplementation, not a copy. The same applies to any third party's code under a license incompatible with MIT/Apache.
If you add a new third-party dependency, it must be permissive (MIT / Apache-2.0 / BSD / ISC / Zlib /
Unicode-3.0 / etc.). about.toml holds the accepted-license allow-list; regenerate the attribution
file with scripts/gen-third-party-notices.sh when the dependency tree changes.
Before you push
cargo fmt --all --check
cargo clippy --workspace --all-targets -- -D warnings
cargo test --workspace
Generated artifacts are checked in and CI fails on drift: include/punktfunk_core.h (cbindgen) and
api/openapi.json (cargo run -p punktfunk-host -- openapi). Match the surrounding code's comment
density and naming. Commit messages end with the Co-Authored-By trailer (see git log).
