  "description": "Cross-language contract fixture for the host-written scheduled-task strings the tasks page and IM notices translate. The backend writes these values to scheduled_task_runs.error and scheduled_tasks.last_error during goal and stop finalization and host-side run bookkeeping; the frontend (core/scheduled-tasks/goal-outcome.ts) and the IM notice renderer map them to readable text, so neither shows the raw value. Version 3 adds the lifecycle vocabulary: lifecycle_events and their lifecycle_reasons (the rows the originating chat shows, GET /api/threads/{thread_id}/scheduled-task-events) and notification_events (the outbox event names).",
