Kotozuchi（言槌）NOTICE ======================= このファイルは、Kotozuchi のリポジトリと配信物（web/game.wasm、web/wasm_exec.js、 ネイティブ版の実行ファイル）に含まれる第三者の著作物と、その利用条件をまとめたもの である。記載は 2026年10月11日時点の go.mod と internal/corpus/rfcsrc/ に基づく。 Kotozuchi Copyright 2026 morststs Kotozuchi 自身のソースコードは Apache License, Version 2.0 で提供する（LICENSE を 参照）。ただし、以下に挙げる出題文と第三者のソフトウェア・フォントには、それぞれに 記載した条件が適用される。 1. 出題文について 2. 組み込んでいるソフトウェアとフォント 3. ライセンス全文 1. 出題文について ----------------- 文章モードの出題文（internal/corpus/data/sentences.txt、全100文）は、次の RFC の 本文から cmd/gencorpus で1文ずつ抜き出したものである。原文は internal/corpus/rfcsrc/ に置いてある。 - RFC 1087 "Ethics and the Internet" Internet Activities Board, January 1989（5文） - RFC 1149 "A Standard for the Transmission of IP Datagrams on Avian Carriers" D. Waitzman (BBN STC), 1 April 1990（17文） - RFC 1178 "Choosing a Name for Your Computer"（FYI 5） D.

Carpenter, Editor (IAB), June 1996（20文） - RFC 2119 "Key words for use in RFCs to Indicate Requirement Levels"（BCP 14） S. Bradner (Harvard University), March 1997（4文） 採用の基準 - 「Distribution of this memo is unlimited.」と書かれ、著作権表示を持たない、 1997年以前の RFC であること。 - 他の著作物を転載・抜粋した部分を含まないこと。 抜き出しの方針 原文を書き換えない。1文を一字一句そのまま使い、単語の削除・置換・言い換えは しない。変えるのは次の2点だけである。 - RFC の72桁固定の折り返しを解いて1行にする（改行と行頭の字下げを空白1個にする）。 - ページ送りのための装飾（ヘッダ・フッタ・改ページ）を落とす。 折り返しのハイフンのために原文の綴りを決められない文は、推測で直さず使わない。 RFC 1178 について RFC 1178 は、Communications of the ACM に載った記事を再掲したものである。 原文の Credits の節には次のとおり書かれており、求められている謝辞をここに 原文のまま載せる。 This essay first appeared in the Communications of the ACM, November, 1989, along with a Gary Larson cartoon reprinted with permission of United Press Syndicate. The text is not subject to copyright, since it is work of the National Institute of Standards and Technology. However, the author, CACM, and NIST request that this credit appear with the article whenever it is reprinted. Libes, D., "Choosing a Name for Your Computer", Communications of the ACM, Vol. 32, No. 11, Pg. 1289, November 1989. 記事に添えられていた漫画は RFC に含まれておらず、Kotozuchi も使っていない。 使っていない RFC RFC 1462 "FYI on 'What is the Internet?'"（E. Krol, E. Hoffman, May 1993）は、 本文の大部分が O'Reilly & Associates の書籍 "The Whole Internet User's Guide and Catalog"（Ed Krol, 1992）の章の再掲で、出版社の許諾を得て RFC に載ったものである。 その許諾が第三者の再利用にまで及ぶかを原文から確かめられないため、 2026年9月13日に出題元から外した。 2. 組み込んでいるソフトウェアとフォント --------------------------------------- 「両方」は WASM 版とネイティブ版の両方に入るもの、「ネイティブ版のみ」は デスクトップ向けにビルドしたときだけ入るものを表す。ライセンスの全文は3章にある。 2.1 ソフトウェア Go の標準ライブラリとランタイム（Go 1.26） 両方 Copyright 2009 The Go Authors BSD 3条項ライセンス（3.2）と特許の許諾（3.3） web/wasm_exec.js（Go 1.26 の lib/wasm/wasm_exec.js を写したもの） WASM 版のみ Copyright 2018 The Go Authors BSD 3条項ライセンス（3.2）と特許の許諾（3.3） github.com/hajimehoshi/ebiten/v2 v2.9.11（Ebitengine） 両方 Apache License 2.0（3.1） github.com/ebitengine/hideconsole v1.0.0 両方 Apache License 2.0（3.1） github.com/go-text/typesetting v0.3.0 両方 Copyright 2021 The go-text authors Unlicense または BSD 3条項ライセンスの選択（3.4） HarfBuzz から移植したコードを含む。各ファイルは 「SPDX-License-Identifier: Unlicense OR BSD-3-Clause」を掲げつつ、移植元の 著作権表示を残している（Behdad Esfahbod、Google, Inc.、Red Hat, Inc.、 Mozilla Foundation、Codethink Limited、Adobe Inc.、Ebrahim Byagowi、 Jonathan Kew、Roozbeh Pournader ほか）。移植元の条件として HarfBuzz の COPYING（3.5）を載せる。一部のファイルにある「Copyright © 1998-2004 David Turner and Werner Lemberg」の表示も、HarfBuzz の COPYING の著作権者の 一覧に載っている（そこでの年は 1998-2005）。 github.com/rivo/uniseg v0.4.7 両方 Copyright (c) 2019 Oliver Kuederle MIT License（3.7） golang.org/x/image v0.45.0、golang.org/x/sync v0.22.0、 golang.org/x/text v0.41.0 両方 Copyright 2009 The Go Authors BSD 3条項ライセンス（3.2）と特許の許諾（3.3） golang.org/x/sys v0.47.0 ネイティブ版のみ Copyright 2009 The Go Authors BSD 3条項ライセンス（3.2）と特許の許諾（3.3） github.com/ebitengine/purego v0.9.0 ネイティブ版のみ Apache License 2.0（3.1） github.com/jezek/xgb v1.1.1 ネイティブ版のみ Copyright (c) 2009 The XGB Authors BSD 3条項ライセンスと Google による特許の許諾（3.6） Ebitengine の internal/glfw（GLFW 3.3 の移植） ネイティブ版のみ Copyright (c) 2002-2006 Marcus Geelnard Copyright (c) 2006-2019 Camilla Löwy ほかに The glfw3-go Authors (2012)、Torsten Walluhn (2012)、 Jonas Ådahl (2014)、Google Inc.
