Materialise a definition of workflow as a working flow workspace — workflow.md with its graph, one step contract per step with real stubs, item cards, measures, integration bindings, platform context-pack and check stubs, and the first generated board — so a human or agent can take over from a running skeleton rather than a blank page. Use after defining or ingesting a workflow, when standing up a second stream, or when an existing workspace needs missing pieces filled in. Part of the flow-driven family.
