- object
  - `graph` WorkflowGraph, required

## Other responses

- `400`: Validation failed — `error` names each offending field (`field: message`).
- `401`: Missing, malformed or unknown credentials (`WWW-Authenticate: Bearer …` is set).
- `403`: The credential lacks the `workflows:manage` scope (body `{ error: "insufficient_scope", required, missing }`), or the team is suspended.
- `404`: No such resource on this team.
- `409`: The workflow is active — pause it before editing.
- `422`: Duplicate node id, self-edge, an edge to a missing node, or more than one edge per branch out of a node.
- `429`: Rate limited (60/min). `Retry-After` gives the seconds to wait; `X-RateLimit-*` headers are sent on every response.
