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
- Prove that Dart's Digest class retains a mutable reference to its backing byte list, uses reference identity for its bytes property comparison, and that AccumulatorSink only emits a digest upon closing.

契约
- assert that a Digest constructed with a mutable List holds that list by reference, so modifying the list externally alters the Digest's bytes, its hex string representation, and its hash code
- assert that comparing raw byte lists of two identical Digest objects directly via the == operator evaluates to false due to Dart's list reference identity check, whereas comparing the Digest objects evaluates to true
- assert that AccumulatorSink remains empty when adding chunks via a chunked conversion sink and only receives a single Digest event when the sink is closed
- assert that calling add on a closed chunked conversion sink throws a StateError
