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。

HOW- 目标
- Construct transactional pipelines with Ecto.Multi: handle Ecto 3's two-arity run callback requirement, contrast with one-arity dynamic operation builders, and inspect pipeline stages

- Ecto.Multi.new
- Ecto.Multi.run
- Ecto.Multi.insert
- Ecto.Multi.merge
- Ecto.Multi.to_list
- Ecto.Multi.prepend
- Ecto.Multi.append

契约
- assert Ecto.Multi.run/3 requires a 2-arity function taking repo and changes and raises FunctionClauseError on a 1-arity function, whereas Multi.insert/3 and Multi.merge/2 accept 1-arity functions receiving only changes
- assert Multi.run/5 with MFA stores the module, function, and arguments tuple, and dispatches with repo and changes prepended as the first two arguments
- assert Multi operations enforce strictly unique step names across the pipeline, raising RuntimeError on single step collisions
- assert Multi.to_list/1 returns operations in chronological pipeline order, whereas internal struct operations store them reversed
- assert Multi.prepend/2 and Multi.append/2 combine distinct transaction pipelines, preserving execution order and rejecting shared names with ArgumentError
