Oh I missed that! 🤦🏼

Deduping this comment with the audit logging. I figured that logging the details of the rego evaluations for every object for every audit run would be too noisy. At present, we only log details for a violation in audit so this should be consistent w the audit behavior now:

gatekeeper/pkg/audit/manager.go

Lines 1106 to 1131 in b7230e0
