形式化验证这东西，以前是按"人年"算的：seL4 微内核 20 人年，CompCert 编译器 6 年。Google DeepMind 刚把 Signal 协议的形式化验证做完了：五人团队，四周，工具是新的 AlphaProof Code。拆开看流程：人只负责写和审数学规约（约 2.6 万行），Gemini agent 生成 650 万行 Lean 证明，再自查一遍，只把 1% 标出来给人复核，其余由 Lean 内核自动校验。最妙的一步是他们顺手验证了自己的验证器：往代码里重新引入两个真实修过的旧漏洞，系统正确证明了那个版本不安全。PQXDH 后量子握手、Triple Ratchet 的前向保密和被攻破后恢复，全部证到机器码层面。规约和证明已开源。#AI #开源
