ADR 0590 §3 ends the choice of a condition source by the keeper's take-over key: the controller is unassigned and the keeper is the one source. The part still read the take-over key, fell back to the controller's condition events when it was absent, and read and watched the controller's lease, which nothing writes any more. It now hears the keeper's events alone and reads neither. Claude-Session: https://claude.ai/code/session_01NcbgfJ9Gum47zkFKWRaovL
