USTC Campus GitLab
A GitLab instance USTC runs on its own domain at git.ustc.edu.cn, with a second LUG-operated instance at git.lug.ustc.edu.cn. GitLab exposes a well-documented REST and GraphQL API, but that contract is GitLab's product, not USTC's engineering, so no specification is saved under this institution. The deployment is recorded because it is a real institutional fact and because it is exactly the kind of surface that gets misattributed: a vendor product API answering on a university hostname.
