Heroku Trails audit logs

There is a need to automate the flow of customers' Heroku platform audit logs to their log repository or security monitoring tools. Today, these audit logs are served through our [Audit Trails](https://devcenter.heroku.com/articles/audit-trail) feature available for export in JSON format.

We are exploring the potential benefits for our customers to automate the flow of audit logs served through Audit Trails.

### Sensitive areas

* `heroku run` and `ps exec` (because that's accessing production data, potentially)

_[Audit Trails for Enterprise Accounts](https://devcenter.heroku.com/articles/audit-trail)_

Start with the linked Audit Trails for Enterprise Accounts reference and clarify the target log repositories, security monitoring integrations, and scope for sensitive commands. Done requires an agreed automation path with defined export and delivery requirements.
