We request the SAT API expose immutable identifiers (email/name at event time) for events tied to deleted learners so we can attribute historical phishing/training activity outside the UI.

Today, the UI shows those rows with a “Deleted” badge, but API responses return relationships.learner.data = null, which prevents programmatic attribution and automated reporting.

This blocks our ability to provide 12 months of history for insurance audits; we need either tombstone fields on events or an include_deleted option/endpoint to surface those identifiers via API.
