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
- In DBAL 4 nested transactions always create SQL savepoints, so an inner rollBack() reverts only to the savepoint and does not mark the outer transaction rollback-only.
- Attempting to disable savepoints via setNestTransactionsWithSavepoints(false) throws InvalidArgumentException because nesting without savepoints was removed in DBAL 4.
- With autoCommit=false, executing queries starts a Level 1 transaction, a manual beginTransaction() increments to Level 2 (savepoint), and commit() immediately restarts Level 1 so the nesting level never drops to 0.
- Calling commit() with autoCommit=true and no active transaction throws Doctrine\DBAL\Exception\NoActiveTransaction.
- CompositeExpression is immutable: calling with() returns a new clone without mutating the caller in place, meaning unassigned calls silently drop filter conditions.
- Result::fetchAllAssociativeIndexed() keys the result by the first column and shifts that column out of the row dictionary values.
- Result::fetchAllKeyValue() requires at least two columns and silently ignores any columns beyond the first two.
