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 creating a conflicting record with clause.OnConflict{DoNothing: true} completes without error, reports 0 rows affected, and preserves all existing database columns unchanged
- assert creating a conflicting record with clause.OnConflict{UpdateAll: true} overwrites all mutable non-primary columns and reports 1 row affected
- assert clause.OnConflict with specific Columns and AssignmentColumns updates only designated fields while leaving other non-conflicting columns at their pre-existing values
- assert clause.OnConflict with Assignments and gorm.Expr evaluates SQL expressions such as counter increments directly during upsert
- assert batch Create with clause.OnConflict applies upsert updates to conflicting rows while inserting non-conflicting rows in the same transaction
