What signals and data governance steps ensure location-level attribution stays accurate when local updates drift from hub content?

Key signals to publish include: (1) a location_id attached to every location-specific Q&A fragment and media, (2) a location-tag in the AI-facing output’s metadata, and (3) content-usage logs that show which local assets were consulted. For governance, implement a Change Control process with approvals, versioning, and an auditable Change Log. Local updates should reference hub content and be validated before propagation to AI-facing outputs; maintain a rollback plan and periodic drift checks to ensure local content remains aligned with central facts. This enables accurate attribution in reports without exposing private data.
