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 hashSync permits omitting salt to default to 10 rounds while async hash rejects with 'Illegal arguments: string, undefined' unless salt or rounds is explicitly passed
- assert genSaltSync(0) evaluates 0 || 10 and silently produces a 10-round salt ($2b$10$) rather than 0 or minimum rounds
- assert genSaltSync clamps rounds 1..3 to 4 ($2b$04$) and rounds 32+ to 31 ($2b$31$), and that passing numeric string '10' throws rather than converting
- assert compareSync and compare return false on non-matching strings whose length is not 60, but throw/reject with 'Invalid salt version' on 60-character non-bcrypt strings
- assert compareSync throws on non-string inputs and throws 'Invalid salt revision' on 60-character strings starting with unsupported revision $2x$
- assert getRounds returns NaN without throwing on empty or malformed strings while getSalt strictly enforces length 60 and extracts 29 characters without syntax validation
- assert encodeBase64 and decodeBase64 use bcrypt's custom alphabet where 0x00 is '.' rather than 'A', causing standard RFC 4648 Base64 'AAAA' to decode to [8, 32, 130]
- assert $2a$, $2b$, and $2y$ produce 60-character hashes that verify with compareSync, while legacy $2$ produces a 59-character hash that always fails compareSync and throws in getSalt
- assert truncates measures UTF-8 byte length with boundary at 72 bytes (36 vs 37 multi-byte characters) and throws on non-string inputs
