Control updates and delayed information
Agree when changes move, how completion is checked and how stale data is identified. Test duplicates, unavailable destinations and retries against representative records. The receiving system should distinguish current information from a transfer still waiting for recovery, rather than presenting every local value as unquestionably up to date.
Bring records that currently disagree
Share the named systems, safe example records, existing mappings and cases where values diverge. Identify who decides conflicts and which interfaces are available. We scope and verify the exchange rules; a reporting dashboard reads and presents information, while synchronisation manages its movement and consistency.
