Projects & Proof · 项目与证据
Every project admitted on one bar: a real user, a real deployment, real data, a real research output, real community impact — or a repeatable system.每个项目只有一条准入线：真实用户、真实部署、真实数据、真实研究产出、真实社区影响，或可复制的系统。
Selected Proof · 精选证据
Every number on this site is exported at build time from our internal source of truth, filtered to public-safe, and stamped with an as-of date. Where a receipt isn’t ready, we show the system — not a number.
Through Long Proof, we track whether a system keeps working — verified, dated, and re-checked on a schedule. The proof isn’t a launch; it’s the arc afterward.
Collaborate · 合作
If it can be shown, we’ll build it — and hold it to a receipt.能被证明的，我们就建设——并让它追溯到证据。
