A delivery and the five-minute reconcile were two paths that applied, ordered only by a lock, and each order it allowed was met live (issues 257, 261, 267). Now both only enqueue: one worker takes the newest declaration held when it starts, applies it once and makes one report, and reports leave in the order they are made. A declaration may carry the controller's lease epoch beside its sequence; one older than what this node applied is refused before anything is touched, counted, logged and reported. A report carries the declaration's epoch and sequence and the host's own report sequence, kept on disk so it goes on increasing across restarts and self-updates. Without an epoch, today's behaviour stands.
