POST Send points, states, events or a heartbeat with an explicitly authorized machine credential. Uses the existing telemetry validation, quotas, deduplication and alarm pipeline. A concrete monitor is required. Run start and completion use the existing events contract. The runtime write gate must be enabled; ingest endpoints still accept only device keys.
