…loyments This change introduces optimized cursor-based pagination for audit log endpoints to improve performance in enterprise environments with large audit datasets. Key improvements: - Added OptimizedCursorPaginator with advanced boundary handling - Enhanced cursor offset support for efficient bi-directional navigation - Performance optimizations for administrative audit log access patterns - Backward compatible with existing DateTimePaginator implementation The enhanced paginator enables more efficient traversal of large audit datasets while maintaining security boundaries and access controls. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

get_item_key assumes a numeric key and applies math.floor/ceil to getattr(item, self.key). When used with order_by="-datetime" (as in the audit logs), value is a datetime and this will raise a TypeError. Consider aligning the key handling with DateTimePaginator.get_item_key for datetime fields.

This branch intentionally slices the queryset with a potentially negative start index (queryset[start_offset:stop]), but Django QuerySets do not support negative indexing and will raise an AssertionError. Allowing negative offsets here is likely to cause runtime errors under the advanced path.

organization_context.member can be None (e.g., non-member contexts), so accessing .has_global_access without a null check can raise an AttributeError when request.user.is_superuser is False. Consider guarding for a missing member in this check.
