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.

pacman_rollback plans from the bus: each package now -> record from the node's cache, else the archive's
exact version, else the archive's repository on the record's date; added packages listed and removed only
when asked; foreign packages untouched. apply is an ask the node's keeper runs as a rollback run through the
root helper's new Rollback act (RootActs, upgrades.go), with rollback.started, rollback.finished and the
after-upgrade check (TakeAsk's rollback case, transaction.go).
