Canvas LTI 1.3 Advantage (Instructure) — tenant
CMU's learning management system serves an LTI 1.3 / LTI Advantage JWKS at canvas.cmu.edu/api/lti/security/jwks, so the LTI standard is genuinely in play in CMU's teaching environment. It is recorded as a tenancy rather than a CMU surface because canvas.cmu.edu is a CNAME to CMU-VANITY.INSTRUCTURE.COM — the LTI implementation, key rotation and contract are Instructure's, running under a CMU vanity hostname. The courses and tool deployments behind it are CMU's; the engineering is not. Included because the tenancy is a real institutional fact and because it is the only `lti` conformance point on a CMU name.
