Camunda 7: assemble and fix executable BPMN

What this skill is for

A Camunda 7 .bpmn is a program the engine runs. The main job here is to assemble a business process by wiring together activities that already exist — reusable service tasks implemented as Java delegates or external-task topics — and add the control flow (gateways, user tasks, DMN, timers, error handling, async) that makes it deploy and run on Camunda Platform 7 (and the API-compatible CIB seven fork).

This skill composes processes; it does not write activity implementations. Writing a new activity (a delegate bean, a worker) is a separate task. When the process needs a step that has no existing activity, you draw a deployable stub (its name and input/output contract) and record it in a follow-up spec for that separate task — you do not invent the Java/worker code here.
