# Self-retiring shim: ships Arch's linux-firmware-cirrus 20260910-2 payload to
# the stable channel while stable's pinned Arch snapshot is still on
# linux-firmware 20260810-2 (which lacks the Dell XPS 13 DX13260 / 1028:0e54
# CS35L56 amplifier firmware aliases, leaving that machine's speakers silent).
#
# Nothing is rebuilt. The signed Arch package is verified against the Arch
# packager key and its payload reinstalled as-is, minus the files that Arch
# moved out of linux-firmware-other in 20260910 (the cs42l45 SDCA tree): on
# the stable snapshot those are still owned by linux-firmware-other 20260810-2
# and would conflict, so they are left to that package.
#
# Versioning is deliberate: 20260810-3 orders above the snapshot's 20260810-2
# and BELOW Arch's real 20260910-2, so as soon as the stable snapshot advances
# pacman replaces this shim with the genuine package in the same transaction
# that upgrades linux-firmware-other, and nothing is lost. Delete this recipe
# once stable's snapshot is at linux-firmware >= 20260910.
