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
- CanonicalizedMap operator []= silently discards assignments for keys rejected by isValidKey without throwing an ArgumentError, leaving map length at 0 and containsKey returning false.
- CanonicalizedMap operator [] returns null and containsKey returns false for invalid keys without executing the canonicalize callback.
- CanonicalizedMap putIfAbsent bypasses isValidKey validation entirely, incrementing length to 1 and storing the value in values while operator [] and containsKey continue to report the key as absent.
- CanonicalizedMap remove on an invalid key returns null and fails to delete entries previously inserted through putIfAbsent from the underlying storage.
- CanonicalizedMap addAll silently filters out invalid keys while inserting valid keys, and update throws ArgumentError for a missing key rather than rejecting an invalid key.
