The five builder images now live on home-ci-core's LAN registry
(192.168.1.58:5010) under content keys — a hash of the ci/ tree (+
rust-toolchain.toml for the cross image). docker.yml builds one only when its
key has no manifest yet, so a push that doesn't touch ci/ costs a curl per
image instead of seven WAN pushes and a set of per-SHA tags that no plain
prune could ever reclaim. Releases pin builders by copying the key manifest
to a vX.Y.Z tag via the registry API — no rebuild, no bytes moved.
Around that: deb/rpm/arch/android/apple/decky get path filters so docs-only
pushes stop lighting up the whole fleet (branch pushes only — tag runs match
tags:, as flatpak/windows-msix releases have proven for months); the
report-only bench job moves to bench.yml (nightly + dispatch) and stops
occupying a fleet slot per push; flatpak caches its Flathub runtimes and
builder state instead of re-downloading multi-GB every run; rpm's cargo
registry cache gets its own key namespace instead of sharing the Ubuntu
jobs'; audit caches cargo bin+registry rather than the whole toolchain dir;
docker-prune.sh loses the local act-cache cap/burst-clear (the cache is
central now — deleting it under disk pressure was how runner-2 ended up
cold-building everything) and gains a leaked-network prune.
