Coverage is not a permanent state
A removal can clear a visible page today while new records arrive tomorrow from customs feeds, partner datasets, or platform refreshes. That does not always mean the original request failed. It means the team needs to know which sources are covered, which dates were reviewed, and when the next refresh is likely to matter.
The useful unit is the relationship
Companies often track pages, but competitors care about relationships: which supplier serves which customer, which product moves through which route, and which shipment pattern repeats. Coverage reviews should ask whether the relationship is still discoverable, not only whether one URL disappeared.
A realistic cadence
High-risk supplier or customer relationships deserve a tighter review loop after new shipment periods. Older, low-risk records can be checked less often. The point is not to search constantly; it is to set a repeatable cadence that matches the commercial sensitivity of the relationship.
