## Recommendations {#recommendations}



### Immediate Actions (P0) {#immediate-actions-p0}
- Add permission checks to Audit, Notification, Media, Feature Flags
- Add `audit_logs:view_only` enforcement
- Fix anonymous access to audit logs and media


### High Priority (P1) {#high-priority-p1}
- Add missing permissions to backend enum for Survey, Analytics, Workspace, Webhook
- Assign orphaned permissions to appropriate roles


### Medium Priority (P2) {#medium-priority-p2}
- Standardize permission naming (snake_case everywhere)
- Replace string literals with enum references
