The keeper reads pacman's database into installed.<node> and writes it only when it differs from the key, says each change as package.changed, and keeps the last value when the list is over the bus's cap, marking the node not current until it fits again; the health names the size. The loop runs over injected states, events, clock, watch and machine, and leaves hooks (start, after a transaction, state watches, wakes) for the upgrade parts of ADR 0508.
