Aalto Open API — Course API (Oodi, deprecated)
The Oodi-sourced course API, still published on the portal and explicitly marked deprecated: "This API source is OODI and should not be used." Swagger 2.0, two paths, superseded by the SISU Course API. Recorded as a real lifecycle event — one of the few observable deprecations in this cohort — with no spec saved, because Aalto tells callers not to use it. The deprecation is signalled only in prose; no operation carries deprecated:true and no Sunset policy is published.
