- Install ccache and wrap the native + arm64 cross compilers via /usr/lib/ccache symlinks on PATH; persist CCACHE_DIR / PATH across steps through $GITHUB_ENV / $GITHUB_PATH. - Restore and save ~/.ccache with actions/cache@v4, keyed by arch + kernel version with a unique per-run suffix to force a save; restore-keys warm-start from a prior build of the same arch (including across point releases). - Print `ccache -s` after the build. Deliberately do not cache out/ (freshly built packages) or the re-cloned kernel source. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
