Merger sites - bad files list

I have been debugging a problem with (temporary) lost merger site permission (see closed issue Question: Not a merger site! #944). I can see that the error occurs (lost merger permission) for fileGet request to a file on bad files list. Adding a list of bad files in my code solved the problem.

Any way to get a list of bad files in ZeroFrame API for merger sites so I can avoid downloading files on bad list? Or alternative a better fileGet error handling in ZeroFrame API. Empty fileGet response for bad files would be OK for me.

该 issue 提到了 ZeroFrame API 及其 fileGet 入口点，但没有指出任何文件或测试。首先定位 fileGet 的处理逻辑和 merger-site 的权限路径，然后确定预期行为是返回错误文件列表还是空响应。选定的行为完成实现并由相关测试覆盖后，即视为完成。
