Consider an example. An AI rewrites a TLS library. The code passes every test. But the specification requires constant-time execution: no branch may depend on secret key material, no memory access pattern may leak information. The AI’s implementation contains a subtle conditional that varies with key bits, a timing side-channel invisible to testing, invisible to code review. A formal proof of constant-time behavior catches it instantly. Without the proof, that vulnerability ships to production. Proving such low-level properties requires verification at the right level of abstraction, which is why the platform must support specialized sublanguages for reasoning about timing, memory layout, and other hardware-level concerns.

过去，钢铁的两大传统主力行业为房地产和基建。但随着地产进入优化期，其用钢量从“十三五”的高位下降到“十四五”的约2.7亿吨，降幅约13%。地产用钢占钢铁总消费的比重也从2021年的32%下滑到2024年的28%。
