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 the pre-1.0 spellings that did NOT change still hold: literal for tag, take for recognize, the count range first in repeat and separated, the stream advanced through &mut, parse_peek returning (remaining, output), and parse reporting the offset where it stopped
- assert alt accepts at most 9 branches on 1.0 so a 12-keyword lexer must nest or pass an array, and both spellings agree on every keyword
- assert alt takes the first matching branch rather than the longest, so reordering the same two branches changes which one wins
- assert a tuple used as a sequence holds at most 11 parsers, so an 11-parser timestamp works and a 13-parser one needs seq! with ignored _ fields
- assert dec_uint stops at a leading zero, yielding 0 and leaving the remaining digits, while digit1 with parse_to accepts zero padding
- assert winnow::Result and ModalResult parse identically and glob-importing the crate shadows core Result, but only ErrMode implements ModalError, so cut_err needs the modal form and stops alt falling through to a catch-all
- assert the built-in expression Pratt parser honours binding power, left and right associativity, and an operator that returns an error
