{"ai_json_enabled":true,"answer":"The Change Centre is the governance surface that coordinates every update to hub facts, locale mappings and proofs. It should enforce that updates are linked to a hub_fact_id, run automated drift checks against language-aware mappings, and require explicit approvals before publishing. Each change is recorded in a Change Log with who, when and why, and a provenance panel shows locale contributions without exposing private workflows. A simple, auditable pipeline keeps the hub as the single source of truth while spoke surfaces reflect local decisions. Three artifacts to version and audit are: 1) hub facts\u2014the canonical, centrally managed facts in the Public Business Brain; 2) locale mappings and proofs\u2014the language-aware representations and their attached proofs; 3) the Change Log\u2014the history of all changes, including locale updates, proof additions, and rollbacks. Versioning these artifacts enables safe rollbacks, clear provenance, and auditable AI-facing outputs that stay stable across locales.","answer_source":"approved_business_brain","category":"Control Centre and Management","category_slug":"control-centre-and-management","created_at":"2026-10-17T19:30:49+00:00","daily_publish_cap":5,"date_published":"2026-10-17","display_date":"2026-10-17","drip_batch":"daily_otc_mixed_intelligence_layer","drip_status":"published_topup","editor_images":[],"editor_media_build":"","editor_videos":[],"id":"otc-daily-20261017-13ed6c8c","image_ids":[],"image_url":"","last_updated":"2026-10-17T19:32:25+00:00","local_cache_status":"pending_airtable_sync","publish_status":"published","published":true,"published_at":"2026-10-17T19:30:49+00:00","question":"What is a practical, governance-first Change Centre workflow for a hub-and-spoke Digital Twin, and which three artifacts should always be versioned and auditable?","question_intent":"natural_otc_conversation","rss_enabled":true,"rss_pub_date":"Sat, 17 Oct 2026 19:30:49 GMT","scheduled_for":"2026-10-17T19:30:49+00:00","schema_enabled":true,"site_key":"owntheconversationonline","slug":"what-is-a-practical-governance-first-change-centre-workflow-for-a-hub-and-spoke-digital-twin-and-which-three-artifacts-should-always-be-versioned-and-auditable","source":"daily_qa_otc_business_brain","source_queue_id":"","source_record_ids":[],"source_type":"daily_qa_otc_business_brain","source_urls":[],"status":"active","tags":["governance","change-centre","digital-twin","daily OTC conversation","core otc","daily drip"],"updated_at":"2026-10-17T19:32:25+00:00"}
