Through production experience and analysis, we've refined the approach to provide comprehensive verification of all spending children before parent deletion, ensuring no child transaction can be orphaned. + +## The Problem + +When a parent transaction becomes fully spent (all its outputs have been consumed by child transactions), we want to delete it to free up storage. However, we must ensure we never delete a parent transaction while its spending children are still unstable - either unmined or subject to reorganization. + +### Risk scenario 1: Unmined child + +1.
