    note: Devialet publishes this API as a PDF reference document, not as a machine-readable specification. This OpenAPI is an API Evangelist derivation that transcribes only what the Revision 1 reference document specifies. It is not published or endorsed by Devialet. Endpoints that the reference mentions in passing but does not specify (`/devices/{deviceId}/identify`, `/groups/{groupId}/sources/current/soundControl/volume`, `/groups/{groupId}/sources/current/playback/position`) are deliberately omitted here and recorded in conventions/devialet-conventions.yml instead.
