TJU Library Unified Discovery (统一检索)
The library's unified discovery front end at find.lib.tju.edu.cn, reachable from outside the campus network and serving a real single-page application titled 统一检索. It publishes no machine-readable contract: /api/, /api/search and /search all return HTTP 200 with the same 1,129-byte SPA shell rather than JSON, so there is nothing here that can be promoted to a contract. Recorded as an institution-operated surface with no institution-published interface. The library's main site is a separate host, home.lib.tju.edu.cn.
