The licence manager follows the nodes' holdings by an event and asks for them with holdings.asked, instead of reading the agent module's state (ADR 0596 §2). The state holdings stays the module's own. Builds: design 39 bus-and-switch §23 Claude-Session: https://claude.ai/code/session_01NcbgfHb9d4T9nq5Q6WqdiJ
