Audit Log Entry Entity ID

Where entityType tells you the kind of record, entityId tells you precisely which one. Together they form a pointer to a single object — for example a particular artifact or a specific excavation unit. This is what makes the audit trail useful for investigation: given any record in Relic, you can pull every entry whose entityType and entityId match it and see its complete change history in order. The value is captured automatically when the action is logged, so it always refers to the real record that was affected.
