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.
Mirrors were generated once and never again and caches never cleaned. The
module holds node-package-manager (hq ADR 0207), declares pacman itself, owns
/etc/pacman.conf whole — [options] cannot take an appended block — with the
union of the enabled repositories and improved options, proven by pacman-conf
in its test, and enables reflector.timer (its config owned) and
paccache.timer. Fifteen tools from a Go bundle; transactions run as transient
units so a call's timeout never kills pacman mid-transaction (to-be 42).
