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
- CollectOneRow consumes the first row without error on multi-row results whereas CollectExactlyOneRow rejects multiple rows with ErrTooManyRows
- assert empty PostgreSQL ranges parse as Valid=true with Empty bound types whereas SQL NULL ranges parse as Valid=false
- assert scanning PostgreSQL infinity or -infinity timestamps into time.Time fails whereas pgtype.Timestamptz and pgtype.Timestamp record InfinityModifier
- assert pgtype.Interval preserves calendar Months, Days, and Microseconds as distinct components
- assert pgtype.Bits stores bit length and MSB-aligned byte representations
- assert nested tx.Begin subtransactions execute savepoint, rollback to savepoint, and release savepoint commands leaving outer transaction intact
