Use when operating or investigating the cfnsync CLI (a tool that syncs a directory of raw CloudFormation templates to stacks). Helpful for choosing between status/plan/deploy/graph/import/force-unlock, interpreting exit codes (0/1/2), performing safety checks around deploy, troubleshooting fail-closed / locking / change-set-ownership situations, and assisting with cfnsync.yaml configuration.
