Pagination drops shipments when several rows have the same update timestamp.
Estimated field mix
A shipment changes status between pages, and partners expect a snapshot the endpoint never promised.

A fast first page still waits for an expensive exact count.
Estimated field mix
A permitted filter scans every shipment despite bounded page size.
