Run CDF Video Data Augmentation

Run the existing Video Data Augmentation workflow end to end. Read the getting-started guide and payload guide before authoring a payload. Treat the checked-in DAG, payload model, and platform manifest as the source of truth if the docs and implementation differ.

Use the bundled references progressively:

• Read setup-and-preflight.md when preparing input or checking a controller/compute environment.
• Read payload-contract.md before rendering or changing a payload.
• Read airflow-direct-api.md before triggering or monitoring a run through the API.
• Read outputs.md before downloading or interpreting artifacts.
• Read troubleshooting.md when a check or run fails, or when the user asks to stop a run.
