jschoubben 68b5febee7 Keep the freshest mirrors first and a tail of four more in pacman's shared list, so a node has a fallback (ADR 0586, issue 1876)

jschoubben 3d1a450406 pacman starts a round's run only once the node's file holds the round's mirror list, and a refresh never writes after a round opened (ADR 0585 §2, §4; review round 1)

The opener ranked the list and took its turn in the same step, so its upgrade started
before the keeper's change hook wrote /etc/pacman.d/mirrorlist, and a failed write on
any node was only logged. A round's run now writes the list first and checks the file
holds the revision the round opened with; otherwise the run is refused with why and
tried again an hour later, as every refused run is. A refresh asks again for a running
round right before its write, since ranking takes minutes.

jschoubben 2b495c4818 pacman keeps one mirror list for the mesh, ranked in the write that opens each round and written by every node (ADR 0585, issue 1876)
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.

jochen d9336d11d0 pacman: the package manager's configuration, mirrors and cache as a module
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).
