create_event_group(label)returns a marker attachable to commands via aevent_groups=[...]option or an execution scope (with group.scope():, propagated through coroutines viacontextvars). Nested scopes compose; markers dedupe by id.eventGroupMarkers. Explicit label marker ids are derived deterministically asSHA1(originalExecutionRunId + label)(sandbox-safe SHA-1 insha1.ts).WorkflowInfo.originalExecutionRunId(plumbed core → lang) and bumps thesdk-coresubmodule to the matching build.Testing
