# Pin QEMU binfmt by DIGEST. setup-qemu-action's previously-bundled
# QEMU segfaulted emulating arm64 dpkg/libc-bin post-install
# ("qemu: uncaught target signal 11 (Segmentation fault)" -> dpkg
# exit 139 at the apt-get layer, Dockerfile:116). The Dockerfile was
# unchanged from prior green builds; the runner's bundled QEMU
# regressed. This digest is the tonistiigi/binfmt image that :latest
# resolved to in the validated green build (~qemu-v10.2.3, 2026-06-08),
# pinned by digest so it cannot drift.
