 - **DAG-based execution**: Tasks are ordered by dependencies using Kahn's algorithm
 - **Parallel batching**: Independent tasks in each batch can run concurrently
-- **Persistent progress**: Execution state saved to `.ralph/progress.json`
+- **Persistent progress**: Execution state saved to `.ralpi/progress.json`
 - **Reflection system**: Each task produces a reflection for downstream tasks
 - **Retry with backoff**: Failed tasks retry with exponential backoff
