Derived by API Evangelist from the live 2026-08-19 response, reconciled against the upstream MirrorZ data contract (mirrorz-org/mirrorz-schema, mirrorz.json/1.5). ZJU self-declares version 1.7, which is above the upstream published schema's 1.5 bound, so the version constraint is relaxed here rather than copied.",
