Rule chain

A rule chain routes device messages and performs tenant-defined actions. The platform itself carries no business logic of its own — business logic lives in rule chains.

Messages (telemetry, lifecycle, alarms, …) flow through linked rule nodes (filters, transforms, enrichments, actions) and are fanned out or stopped by each node's routing. A device profile or an individual device may bind a rule chain, so all its traffic is processed by it.

The platform only supplies generic nodes and transport; tenants define every rule.
