- Mission CRUD: createMission, loadMission
- TASKS.md parser/writer: parseTasksFile, writeTasksFile, updateTaskStatus
- Task runner: runTask, resumeTask (spawns agent via child_process)
- Status aggregation: getMissionStatus, getTaskStatus
- CLI: coord init | run | resume | status
- Depends on @mosaic/types and @mosaic/queue workspace:*
