Dashboards are not control towers
Many companies call what is, in practice, a KPI aggregator panel a control tower. A real control tower needs to observe, decide, act and learn. In NexLog OS, the control tower consumes the event ledger (`businessEvents`) from all modules, applies exception engine on deviations, scales versioned playbooks and exposes digital twin for what-if simulation. Consolidated KPIs (unified OTIF, cost-to-serve, service footprint) live in the same dashboard, without ETL.
