# Save the draft (lenient, structural-only)

> Partial save of the draft definition/schemas. Runs STRUCTURAL (Zod) validation only — WIP graphs are allowed. Send the `rev` you last read; a stale rev returns 409. `rev` is trigger-owned and must not be sent in the payload. `output_schema` is optional and NOT enforced at run time — leave it unset unless you need a declared boundary contract; the actual output shape is whatever the last flow position returns (see the step-level schemas: tool `outputSchema`, agent step `output_schema`).
