  "summary": "Implemented parent task model inheritance for subtasks. Modified `/subtasks/create-tasks` endpoint in routes.ts and `taskCreate` tool in triage.ts to pass parent task's model fields (`modelProvider`, `modelId`, `validatorModelProvider`, `validatorModelId`) to subtasks. Added 4 new tests (2 for dashboard, 2 for engine) verifying inheritance and graceful fallback when parent is missing. Build passes, all new tests pass, changeset created.",

      "outcome": "The specification clearly defines the mission: ensuring subtasks inherit parent task AI model settings (`modelProvider`, `modelId`, `validatorModelProvider`, `validatorModelId`) in both the dashboard subtask breakdown and triage agent flows. The approach is sound—fetch the parent task and pass its model fields during subtask creation. However, there is a significant line number inaccuracy in the triage.ts reference that should be corrected to prevent implementation confusion."
