How should a brand structure its AI-facing data to enable reliable, brand-wide cross-language summaries in AI Mode while ensuring sensitive internal processes stay private?

Publish a centralized Public Business Brain with deterministic facts and language-aware mappings that point to the same fact IDs across languages. Attach verifiable sources and proofs to each fact, and structure Q&A around topic-to-proof relationships. Keep private procedures in a separate Operational layer with strict access controls. Use a Control Centre to version updates and ensure localizations reference the hub’s identifiers so AI Mode can generate consistent cross-language overviews while protecting private data.
