What governance checks ensure local AI outputs remain consistent with central facts when updates happen asynchronously?

Implement a Change Control process with clearly assigned owners for each data stream, strict versioning, and cross-location review. Use a centralized Change Log to document what changed, why, and when, and require approvals before updates propagate to AI-facing outputs. Maintain a canonical central fact set in the Business Brain and attach locale-specific updates to spokes that reference this core content. Include automated drift checks and a rollback plan so asynchronous updates don’t break existing AI citations. This provides auditable consistency across brands while allowing local relevance.
