Ethan Archive 是一座个人数字基础设施知识博物馆。展品不是文章，而是一层层可以核验的事实：这个号码今天还能收码吗？这个免费额度今天还是这个数字吗？这家银行的门槛今天还成立吗？Ethan Archive is a personal museum of digital infrastructure knowledge. The exhibits are not articles but layers of verifiable fact: does this number still receive codes today? Is this free quota still the same number? Does this bank's threshold still hold?
所以每篇指南分开记录发布日期、更新日期、最后核实日期、证据等级和变更历史。AI 可以帮忙发现变更候选，但不能仅凭一条社区消息改官方状态。人核验之后，才能写入可用、已变化或不可用。Every guide records publication, update, last verification, evidence grade, and change history separately. AI may surface change candidates, but a single community post never flips an official status. Only human verification writes Available, Changed, or Unavailable.
这不是银行、VPS、eSIM 或加密货币博客。那些只是模块。内容用 Markdown 写在 Git 里，构建成静态站点，部署在 Cloudflare。This is not a banking, VPS, eSIM, or crypto blog — those are just modules. Content lives as Markdown in Git, builds to a static site, and deploys on Cloudflare.
