Arch shipped qt6-base 6.11.2-2 on 2026-08-20, and the published 0.3.0.r20.g28771c7-1, built against 6.11.1, stopped starting: undefined symbol _ZN23QUntypedPropertyBindingC1EP23QPropertyBindingPrivate, version Qt_6_PRIVATE_API. quickshell-check.hook caught it post-transaction, but detecting is all it does, so pacman logged the failure and omarchy-update-restart went on to restart a shell whose binary could no longer launch.
The git rev has not moved, so the rebuild only reaches anyone through a pkgrel bump. rebuild_on names the three Qt packages quickshell actually links against: qt6-base for Core, Gui, Widgets, Network, DBus and OpenGL, qt6-declarative for Quick and the Qml libraries, qt6-wayland for WaylandClient. rebuilt_against is seeded with the versions this rebuild will link against, so bin/sync-rebuilds starts from a correct baseline and fires on the next Qt release rather than repeating this one.

Quickshell 0.3.0's qs kill returns before the instance exits, which is
what forces omarchy-restart-shell to track pids and wait for death
itself. Master fixed kill to block until the instance is gone (025c709),
so ship our own build pinned at e649d24 until a release catches up.
The #commit= pin plus sync:false keeps upgrades entirely manual: nothing
rebuilds or resyncs until the sha is bumped by hand. Note quickshell
links Qt private APIs, so every Arch qt6 bump needs a pkgrel bump and
rebuild here (the packaged quickshell-check hook warns users if we lag).
