  title: Amazon EventBridge Archive Event Bus
  summary: Create a bus, resolve its ARN, then archive matching events from it.
  description: >-
    Sets up durable event capture: the workflow creates a custom event bus,
    describes it to resolve the ARN that an archive must reference as its event
    source, and then creates an archive that retains matching events from that
    bus. Every step spells out its AWS JSON request inline — including the
    documented X-Amz-Target header — so the flow can be read and executed without
    opening the underlying OpenAPI description.

  summary: Create an event bus and an archive that captures its events.
  description: >-
    Creates a custom event bus, describes it to obtain its ARN, and creates an
    archive that uses that ARN as its event source so matching events are
    retained.
