# Third-party notices

Keyboard Warrior is built on open-source libraries and includes bundled creative works.
Copyright remains with the respective authors and contributors.

The Cargo table is the deterministic union of non-development dependency graphs for
the locked Linux, both macOS architectures, Windows, and WebAssembly targets. It
includes build dependencies because they participate in producing shipped artifacts.

## Components needing additional notice

### Mozilla Public License 2.0

The `symphonia` family and `option-ext` are distributed under MPL-2.0. The
copies used by Keyboard Warrior are unmodified. Their corresponding source is
available from the upstream projects:

| Component | Source |
| --- | --- |
| `symphonia` and its `symphonia-*` crates | https://github.com/pdeljanov/Symphonia |
| `option-ext` | https://github.com/soc/option-ext |

The MPL-2.0 text is available at https://www.mozilla.org/MPL/2.0/.

### libopus

Native builds link libopus through the Rust `opus` and `audiopus_sys` crates.
libopus is copyright the Xiph.Org Foundation and contributors and is
distributed under the 3-clause BSD license. Upstream source is available at
https://github.com/xiph/opus.

### macroquad browser support

The macroquad Rust crate is used without source changes and is distributed
under MIT OR Apache-2.0. Upstream source is available at
https://github.com/not-fl3/macroquad.

`web/mq_js_bundle.js` is derived from `js/mq_js_bundle.js` in macroquad 0.4.16
with local corrections for quad-net's strict-mode declaration and browser
keyboard input. Apostrophe/slash physical codes match miniquad's protocol;
characters forwarded while preventing browser shortcuts retain the OS layout.
`scripts/check_vendored_assets.py` verifies the locked crate checksum, upstream
file hash, exact patches, and committed output.

### ProggyClean

The committed `assets/ProggyClean.ttf` is byte-for-byte identical to
`src/ProggyClean.ttf` in the locked macroquad 0.4.16 crate. Its SHA-256 is
`527d2a443ce051f93f7e77b855609722b8cb220a9f104b4aa037be5c90b71324`.
macroquad distributes that crate under MIT OR Apache-2.0 and identifies the
font as ProggyClean by Tristan Grimmer (https://proggyfonts.net).
`assets/font.png` is a raster atlas derived from that file by
`examples/make_font.rs`.

### Kenney Interface Sounds

The PERFECT, GREAT, and GOOD judgement samples and chart-guide tick are adapted
from `pluck_001`, `select_001`, `click_001`, and `tick_001` in Kenney's
Interface Sounds 1.0 pack. Kenney released the pack under Creative Commons Zero
1.0 (CC0). The source pack is available at
https://kenney.nl/assets/interface-sounds and its CC0 dedication is at
https://creativecommons.org/publicdomain/zero/1.0/.

### Recorded keyboard sounds

Menu typing uses five keystroke recordings from **vintage keyboard** by
**jim-ph**, released under Creative Commons Zero 1.0 (CC0):
https://freesound.org/people/jim-ph/packs/12363/.
Freesound sound IDs 194795–194799 were obtained as public high-quality MP3
previews, trimmed, level-matched, and converted to PCM. Source URLs and hashes
are retained in `assets/sfx/typing/sources.json`. The CC0 dedication is at
https://creativecommons.org/publicdomain/zero/1.0/.

Confirmations use **enter key** by **uEffects**, Freesound sound ID 180997,
also released under CC0: https://freesound.org/people/uEffects/sounds/180997/.
Its public high-quality MP3 preview was trimmed, level-matched, and converted
to PCM; the source and checksum are retained with the other keyboard recordings.

## Bundled music and charts

Keyboard Warrior ships with the songs below. Each is listed with the licence its
rightsholder publishes it under and the charter credited with its chart.

| Song | Artist | Music licence | Chart credit |
| --- | --- | --- | --- |
| Code Monkey | Jonathan Coulton | CC BY-NC 3.0 | NoisyPuppet |
| Creepy Doll | Jonathan Coulton | CC BY-NC 3.0 | RockGamer |
| Re: Your Brains | Jonathan Coulton | CC BY-NC 3.0 | Harmonix |
| Dirtbag | Brad Sucks | CC BY-SA 3.0 | JRabes |
| Certain Death | Brad Sucks | CC BY-SA 3.0 | MB1Nightmare & Greninjo |
| There's Something Wrong | Brad Sucks | CC BY-SA 3.0 | MB1Nightmare & Greninjo |

### Packaging transformations

- Native: At package time, non-lead Opus stems are summed and re-encoded as one Opus backing track; lead stems and chart bytes are retained separately.
- Web: For the browser, Opus audio is decoded, non-lead stems are summed, the combined mix is scaled when needed, and backing/lead audio is re-encoded as Vorbis with restoration gain recorded in metadata; chart bytes are copied into full and chart-only containers.
