McGill Course Catalogue on CourseLeaf (tenant)
McGill's official course catalogue, published on CourseLeaf. It carries an undocumented but live machine-readable course-detail endpoint — GET /ribbit/index.cgi?page=getcourse.rjs with a space-separated course code returns XML with a CDATA course block (verified 200, text/xml, for COMP 202 and BIOL 112 on 2026-08-30; an unknown code returns an empty courseinfo element, also 200). No contract is saved: the endpoint is CourseLeaf's product surface, identical across every CourseLeaf customer, and saving it under McGill would credit the institution with a vendor's design. Recorded because the catalogue data is McGill's and a course catalogue is one of the surface classes a university genuinely operates.
