System-wide architectural views. The conventions tree describes the rules (DDD layering, ports and adapters); this tree describes the shape of the running system.

• Context — system boundary and external actors.
• Containers — deployable units and their responsibilities.
• Components — internal structure of significant containers.
• Code — key class-level diagrams where helpful.
