  "mechanism": "The active command structure that organizes {{solver_node}} instances into a coordinated {{topology}} for solving a {{task}}. Unlike a passive data tree, this structure represents the flow of Authority (downwards via delegation) and Results (upwards via reporting). Resources ({{budget}}) cascade from the {{root_solver}} to children; outcomes propagate back up. Each node is a unit of attribution — failures can be traced to specific {{solver_node}}s for {{localized_learning}}. At decomposition time the structure is tree-like, but at execution time fan-in and deduplication are permitted, making the runtime a DAG.",
