Yale Course Search and University Publications (CourseLeaf tenancy)
Yale Course Search (courses.yale.edu) and the Yale University Publications bulletin (catalog.yale.edu) are the institution's public course-catalog surfaces. Both are Leepfrog CourseLeaf tenancies — courses.yale.edu is a CNAME to yale-fs.courseleaf.com and catalog.yale.edu to yale-public.courseleaf.com. The catalog data is Yale's and the surface carries Yale's identity, but the platform, the software and any API belong to Leepfrog. No machine-readable contract is saved under Yale's slug for it.
