CMDBUS™
A command bus / control-plane architecture.
CMDBUS is an architectural model in which external inputs -- email, API calls, events, or messages -- are treated as structured commands entering a control plane.
Each command is evaluated against policy and context, transformed into explicit actions, and recorded as part of a durable, causally linked event history.
This approach prioritizes operational clarity over implicit behaviour, ensuring that system state can be understood, reconstructed, and reasoned about over time.
CMDBUS defines the model; implementations vary.
This page describes the conceptual model. A reference implementation is available on GitHub.
