+# `unmaintained` warnings (audiopus_sys via opus, paste via utoipa-axum). Both are transitive, at
+# their latest published version with no successor, so there's nothing to bump — left visible on
+# purpose so we keep getting the maintenance signal; they do not fail CI. (rustls-pemfile was dropped
+# 2026-06-29 by removing axum-server's unused tls-rustls feature + moving our own PEM parsing to
+# rustls-pki-types; memmap2's unsoundness was fixed by the 0.9.11 bump.)

+# Contributing to punktfunk
+
+Thanks for your interest in contributing!
+
+## 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
+
+```sh
+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`).
+
+See [`CLAUDE.md`](CLAUDE.md) for the full build/test/run guide and design invariants.

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or Derivative
+          Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses

+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or Derivative

+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,

+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+FFmpeg — third-party component notice
+=====================================
+
+This product bundles unmodified shared libraries from the FFmpeg project
+(avcodec / avutil / avformat / swscale / swresample and their dependencies) as
+separate dynamic-link libraries (DLLs). punktfunk uses them only for hardware
+video encode (AMD AMF / Intel QSV) on the host and hardware/software video
+decode on the client.
+
+License
+-------
+The bundled FFmpeg libraries are distributed under the GNU Lesser General Public
+License (LGPL), version 2.1 or later. The bundled builds are the "lgpl-shared"
+configuration — they do NOT include any GPL-licensed components (notably they do
+not include libx264 or libx265; punktfunk does not use them). The full text of
+the LGPL accompanies this notice (see the COPYING.LGPLv2.1 / LICENSE files in
+this directory; if absent, see https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html).
+
+How punktfunk complies (dynamic linking)
+----------------------------------------
+punktfunk links FFmpeg only dynamically: the FFmpeg DLLs are shipped as separate
+files alongside the application and are not statically combined into the
+punktfunk executable. You may replace these DLLs with your own ABI-compatible
+build of FFmpeg, which satisfies LGPL section 6 (the right to relink the work
+against a modified version of the library).
+
+Source code
+-----------
+The bundled binaries are unmodified builds produced by the BtbN/FFmpeg-Builds
+project. The exact source for the FFmpeg release used is available from:
+
+  * FFmpeg project source:   https://ffmpeg.org/download.html  (release n7.1)
+  * Exact build recipe:      https://github.com/BtbN/FFmpeg-Builds
+
+A copy of the corresponding FFmpeg source for the version shipped here is
+available on request from the punktfunk maintainers (https://git.unom.io/unom/punktfunk).
+
+Trademark
+---------
+FFmpeg is a trademark of Fabrice Bellard, originator of the FFmpeg project.
+punktfunk is not affiliated with or endorsed by the FFmpeg project.

+"""Generate THIRD-PARTY-NOTICES.txt for the Rust workspace.
+
+Offline, dependency-free attribution generator. It reads `cargo metadata`, then for every
+third-party crate (everything that is NOT a first-party workspace member) it pulls the crate's
+*actual* LICENSE/COPYING/NOTICE text out of the local cargo registry cache (or the in-tree
+vendored source for path deps), deduplicates identical license texts, and emits a single
+notices file: a per-crate manifest followed by the verbatim license texts.
+
+This satisfies the binary-distribution attribution duty for the permissive (MIT/BSD/ISC/Zlib/
+Apache/Unicode/etc.) crates linked into shipped punktfunk artifacts. `cargo about` (see
+about.toml) produces an equivalent, network-augmented result in CI; this is the dependency-free
+fallback that also runs locally and is committed as a baseline.

enricobuehler	7591425f6f	feat(clients): in-app OSS / third-party-license screens Surface THIRD-PARTY-NOTICES.txt in every GUI client (the desktop packages already ship it as a file; this adds the on-glass screen): - Linux: Preferences -> About -> Third-party licenses (adw::AboutDialog with the app license + Legal sections; include_str! the root notices). - Apple: macOS About tab / iOS+tvOS Acknowledgements link; notices bundled as PunktfunkKit SPM resources, read via Bundle.module (the Xcode app links the SPM product, so they ride along - no .pbxproj edit). - Android: Settings -> About -> Open-source licenses (reads the bundled asset). - (Windows landed earlier in `d1d2ca2`: Settings -> About -> Third-party licenses.) gen-third-party-notices.sh now copies the generated file into the Apple Resources/ and Android assets/ trees so the in-tree copies never drift.

enricobuehler	d1d2ca293d	feat(pairing): seamless no-PIN delegated approval (host parks the knock, clients add "Request access") Web-console "Approve" (delegated pairing, roadmap §8b-1) was unreachable: every client routed a fresh pair=required host straight to the SPAKE2 PIN ceremony, so no "knock" was ever recorded; and an unpaired connect was rejected+closed with no way to resume after approval. The backend + console were complete but had no client-side trigger and no post-approval admit path. Host (native_pairing.rs, punktfunk1.rs): an unpaired identified knock is now PARKED instead of rejected — it releases its NVENC session permit, awaits an operator decision (NativePairing::wait_for_decision, woken by a Notify on approve/deny), and on approval re-acquires a slot and admits the SAME connection with no reconnect. QUIC keep-alive (4s/8s) holds the parked connection warm. The pairing gate moves out of the HANDSHAKE_TIMEOUT-bounded handshake future; approve_pending is reordered read-then-add and wait_for_decision double-checks is_paired to close a "neither pending nor paired" race. New PENDING_APPROVAL_WAIT (180s). Tests: delegated_approval_admits_after_knock now approves mid-park (no reconnect) + new wait_for_decision_approve_deny_timeout unit test (108 host tests green). Clients (Linux/Apple/Windows/Android): a fresh pair=required host now offers "Request access" alongside the PIN ceremony — a plain identified connect with a ~185s handshake budget and a cancelable "waiting for approval" UI; on success the host is saved as paired, and cancel returns the UI immediately while a late- resolving connect is torn down silently via a per-attempt flag. Apple reuses the existing C-ABI timeout_ms (no ABI change); Windows adds SessionParams.connect_timeout + a RequestAccess screen; Android adds a timeoutMs arg to the nativeConnect JNI seam (both sides + both callers). Linux built + clippy + fmt clean; Apple/Windows/ Android pending their CI/on-device compiles. SPAKE2 ceremony reviewed end-to-end against the spake2 0.4 contract — correct, no changes needed.

enricobuehler	705a8fa94e	chore(deps): drop unmaintained rustls-pemfile; axum-server 0.7 -> 0.8 axum-server was used only for the plain-HTTP nvhttp listener, but we enabled its tls-rustls feature (HTTPS is hand-rolled over tokio-rustls) — and that feature was what pulled the unmaintained rustls-pemfile (RUSTSEC-2025-0134). Drop the feature, bump axum-server to 0.8 (0.8 also no longer pulls it), and move our own PEM parsing in gamestream/tls.rs to rustls-pki-types' PemObject (the same path punktfunk-core/quic.rs already uses), removing our direct rustls-pemfile dep too. Net: rustls-pemfile fully gone; dependency graph trimmed 547 -> 529 crates (the tls-rustls feature also dragged in prettyplease + a wasm-tooling chain). cargo audit now reports only audiopus_sys + paste (transitive, latest, no successor). 108 host tests + clippy + fmt green.

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".

Re-apply and lock it in. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-29 06:05:10 +00:00
