distribution and gitea each carried the same idle bound (one expiring key per open transfer, its end dropping a transfer idle for 24 hours or arming it again for the rest) and the same read of incoming's cap from its binding: the second instance of the kind, so it moves to the Receiver every holder shares. Arm is called on each open that leaves a transfer open, a key not written failing it loudly; Expired handles a key's end; Bound reads the binding's cap over Cap. BusArm, BusCap and FollowIdle bind them to the holder's own state and objects. Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
