update_node_config

Merge fields into a node's data in the active flow. Use "label" to rename; "description" for process/io; "condition" for decision (the text shown under the diamond, e.g. "latency > 2s"); "variant" ("start" or "end") for start_end; "borderColor" to tint a node's border as a persistent marker — a CSS colour string, or one of "red" / "amber" / "green" / "blue" / "purple" (pass null to clear; a malformed colour is ignored). e.g. after evaluating a rule, set { borderColor: "red" } on the decision node. Only the keys you pass are changed. Returns { success: false, error } if the node id does not exist, otherwise { success: true }.
