Dedicated endpoint management API rejects unknown fields and parameters with HTTP 400
The dedicated model inference management API now rejects unknown JSON request-body fields and unknown query parameters with HTTP 400. The response names the field (for example unknown field "inactive_timeout") instead of silently ignoring it. Remove retired or misspelled keys from clients that still send them.
