Testing exposed real bugs: patched files were getting new inodes, so hardlinked copies kept stale, unpatched content. The fix now groups files by inode,…
Second theme: shrinking CI surface. PR 23677, merged by Patrick Linnane, drops Intel from the Homebrew/core build matrix entirely, following persistent macOS 14 Intel issues. PR 23679 follows up by dropping Intel to Tier 3 support in diagnostics and documentation. Separately, PR 23675 and PR 23684 both target test…
