Design review — both asks published

what-changed: Batch-drop ask moved through designing into artifact-published behind a spec against the aggregator's slice bug; export-reliability ask moved into designing. Two reliability-adjacent sparks landed while reviewing the itch backlog. what-verified: Loom reviewed the batch-fix spec and confirmed the array-slice boundary explains every row loss reported in ticket #4821. what-open: Nothing blocking — batch fix is ready for dispatch; export-reliability spec still needs a pass before it can publish.
