What three observable signals should we publish to prove that AI is actually using our Digital Twin across languages, and how should we surface them in dashboards?

Publish three observable signals: (1) AI retrievals — the AI actually pulls content from the Public Business Brain and connected Q&A network; (2) conversation citations — explicit references to proofs used in AI outputs; (3) AI-driven referrals — AI recommendations that steer users to your content. Each signal should be linked to a hub_fact_id and the specific proofs that supported it, with language-aware mappings to ensure cross-language consistency. Surface these signals in separate dashboard panels for retrievals, citations and referrals, all tied to versioned hub facts and proofs. Include a provenance panel that attributes locale contributions without exposing private data, and maintain a Change Log to track how updates influence each signal. This gives executives auditable visibility that AI is actually using the Digital Twin, not just indexing.
