技術ドキュメント、README、API仕様書、技術書、記事の作成ガイド。 【最重要】実測データ・検証結果の扱い方 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 絶対に守るべきルール: 1. 実際に測定・検証していないデータを「実測」として書かない 2. 架空の数値を具体的に記載しない 3. 「〜したところ」「検証した結果」など、実証したかのような表現を使わない 4. Before/Afterに具体的な数値（メモリ使用量、処理時間等）を書かない 5. 公式ドキュメント・論文・信頼できる情報源のみを引用 読者は「著者が実際に検証した」と受け取ります。 検証していないのに検証したように見える表現は、読者の信頼を裏切る行為です。
