# listWorkflowGraphRevisions

A workflow's save history, newest first: when, who (`source` HUMAN, AGENT or SYSTEM; `actorName`; `agentRunId` for an agent's save), the version it wrote, and `diff`: what changed against the save before (`summary`, edited steps and keys, settings, rename). A save through this API, the assistant's included, reads HUMAN under the person's name. When `diff.hasPredecessor` is false there is no earlier save to compare (its first save, or older history trimmed): go by `summary`, never the lists, as that save's change. `absorbedUnjournaledEdits` means it includes edits made outside the editor; say so.
