When we reach out across the stars, we speak not for a nation or corporation, but for all humanity. The search for extraterrestrial intelligence reminds us of our cosmic context and our shared destiny as a spacefaring civilization. This standard embodies the principle of ํ™์ต์ธ๊ฐ„ (ๅผ˜็›Šไบบ้–“): to benefit all people widely. Whether we communicate with distant human colonies or alien civilizations, let us do so with wisdom, compassion, and the hope of mutual understanding. --- **May we never stop listening. May we someday hear an answer.** *"Somewhere, something incredible is waiting to be known."* โ€” Carl Sagan --- ยฉ 2025 WIA (World Certification Industry Association) MIT License โ€ข ํ™์ต์ธ๊ฐ„ (ๅผ˜็›Šไบบ้–“) โ€ข Benefit All Humanity
