"""
Malicious Addons Detection.

This runs once a week to emit a trained model to GCS.

Source code is in the private [mad-server repository](https://github.com/mozilla/mad-server/).

*Triage notes*

The way the app was designed it is decoupled from Airflow and will pull all data since the last
successful data pull. What this means if we have a failed DAG run followed by
a successful DAG run it will cover the data from the previous run.

So as long as the most recent DAG run is successful the job can be considered healthy
and not action is required for failed DAG runs.
