nr_get_flowGet a single tab with all nodes — by name or ID
nr_search_nodesSearch nodes by name, type, or JavaScript code content
nr_get_function_codeExtract full JS code from function nodes (incl. init/finalize)
nr_get_node_configFull config with computed upstream/downstream connections
nr_get_flow_contextRead flow-level context variables
nr_safe_deployDeploy changes with optimistic locking — never reorders tabs
nr_create_nodesBatch-create nodes/groups in a single deploy
