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。

契约
- assert IndexedRandom::choose returns Option while choose_weighted returns Result<&T, WeightError>
- assert an empty slice returns None from choose and Err(InvalidInput) from choose_weighted
- assert all-zero weights return Err(InsufficientNonZero) while negative and NaN weights return Err(InvalidWeight)
- assert IndexedRandom::sample returns distinct references, caps an oversized request at the slice length, and sample_array returns None when the array is too large
- assert IndexedMutRandom::choose_weighted_mut returns a mutable selected item and SliceRandom::shuffle preserves the input elements
- assert Alphanumeric::sample has item type u8, char conversion builds a String, and SampleString builds the requested-length String directly
