OptionalaccessOptionalactorOptionalattributesOptionalcascadeThe definition's name — delete addresses the workflow, not a doc id.
OptionalgrantsOptionalgrantsURL path for grant resolution — see StartInstanceArgs.grantsFromPath.
OptionalreasonFree-text reason stamped on each cascade-abort history entry.
OptionalversionDelete only this deployed version. Default: every deployed version.
Abort every non-terminal instance pinned to the targeted versions before deleting. Instances are ONLY aborted — instance documents are never deleted; they stay in the lake as the audit record. Without this flag the delete refuses when such instances exist.
