Use the parent ledger to attest membership before the first child snapshot so placement cannot race creation. Bind retained conversations, catalog pushes and actions to their selected origin with separate replica, layout and pending-state owners.
Keep queuing, permission codes and reconnection independent of transport selection. Track submitted request outcomes generically while retaining connection error codes and structured causes.
Multiplex logical sessions over the monitored daemon connection and wrap original binary bytes in routing headers. Admit channels under their authenticated parent and current grants; preserve scoped delivery and physical send completion.
