Each node's reflector ranked its own list on its own timer, and on 2026-10-31 one node's
lagging first mirror left it a Node.js version behind the rest. The list is now the
module's state mirrors, key list: the node that opens a week's round ranks it with the
module's reflector options, keeps only mirrors whose last sync is no older than the
newest found, and the round's key names the list's revision. Every keeper writes
/etc/pacman.d/mirrorlist whole from the key through the root helper's new verb
mirrorlist, when the key changes and when the file differs, and never writes an empty
or unreadable list. reflector.timer is declared stopped and disabled, and reflector.conf
saves nothing. pacman_mirrors answers the shared list, its ranker and age and whether
this node's file matches; with refresh it asks this node's keeper to rank again,
refused while a round runs, naming it. The round's integration test proves the opening
write and both nodes' files.

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).
