Human Operators in Distributed Financial Systems: When People Become Part of the Architecture

In practice, these systems depend heavily on human intervention. Operators investigate inconsistencies, trigger reconciliation processes, approve exceptional transactions, manage incidents, and recover systems under failure conditions. These actions are not external to the system. They are part of the system itself. This ar
