- [Check Geographic Coverage of Latest Views](https://videotomd.com/b/text-local-guard-geographic-view-completeness-4b39c211bf17/index.md): Expose a latest-record view that silently drops part of its intended service area.
- [Gate batches with content contracts](https://videotomd.com/b/text-local-gate-data-batches-with-contracts-0056c611361d/index.md): Quarantine invalid rows before merge; abort only when contamination exceeds an explicit threshold.
- [Assign Table Values by Header Geometry](https://videotomd.com/b/text-local-extract-table-values-by-header-geometry-77cd0b234631/index.md): Map numeric cells to header positions so extra columns cannot silently shift field assignments.
