What criteria determine which proofs are eligible to be cited in AI outputs across languages, and how do you manage proof quality in the Public Business Brain?

Proofs cited by AI across languages should be authoritative, publicly accessible, and directly linked to a hub_fact_id. Each proof must be versioned, language-compatible, and auditable, with privacy boundaries respected by keeping private procedures in a separate Operational layer. Implement a Proof Registry that assigns proof_ids to hub facts, requires verification against the hub_fact_id, and enforces consistency of translations referencing the same hub_fact_id. A governance process should review proofs for accuracy and sufficiency before publication, and changes to proofs should appear in a Change Log so executives can trace how citations evolve over time.
