DAG Layers ​
| # | Layer | Steps | Compensation |
|---|---|---|---|
| 1 | validate | agents._ft-dataset.validate | — |
| 2 | build-examples | agents._ft-dataset.build-examples | agents._ft-dataset.mark-failed |
| 3 | upload | agents._ft-dataset.upload | agents._ft-dataset.mark-failed |

Execution Flow ​
Compensation ​
When any layer fails, its compensation steps run in reverse order to roll back the work completed so far.
Sub-workflows ​
| Sub-workflow | Step name |
|---|---|
agents._ft-dataset.validate | validate |
agents._ft-dataset.build-examples | build-examples |
