I watched this happen at an energy sector client: the playbook was configuring a 12-node cluster, got to node 7, lost the VPN connection, and left 5 nodes in a partially configured state that did not match the other 7. The team spent a day figuring out which tasks had run on which nodes. This template wraps Ansible in a CI pipeline with idempotency verification, diff mode for change preview, and per-environment inventory management.\u003c\/p\u003e\n\n\u003ch3\u003ePipeline Stages\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003elint\u003c\/strong\u003e — \u003ccode\u003eansible-lint\u003c\/code\u003e with custom rules.
