本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- In rand 0.9+, thread_rng() and .gen()/.gen_range() are replaced by rand::rng() and .random()/.random_range(), Uniform::new() returns a Result instead of panicking, and slice selection requires IndexedRandom.

契约
- rand::rng() initializes the thread-local generator instead of deprecated rand::thread_rng()
- rng.random() and rng.random_range() replace removed .gen() and .gen_range() methods
- rand::distr::Uniform::new() returns Result<Uniform, UniformError> rather than infallible construction or panicking
- rand::seq::IndexedRandom provides choose and choose_multiple on slices replacing rand::seq::SliceRandom
- rand::distr::SampleString with Alphanumeric generates random ASCII strings
- SeedableRng::seed_from_u64 produces deterministic repeatable random sequences across generator instances
