detectFromBrowserSignals declared 'macos-x64' in its Arch union but could never return it: every non-Windows, non-Linux UA fell through to 'macos-arm64', silently handing Intel Mac users the Apple Silicon binary snippet. Since Big Sur the macOS UA reports 'Intel Mac OS X' on Apple Silicon too, so UA parsing fundamentally cannot distinguish the two — only User-Agent Client Hints can. The component already requests architecture/bitness hints; the detector now honors them on the macOS branch (x86 -> macos-x64). Without hints the default stays arm64 (every Mac sold since late 2020) and the page's existing arch chooser remains the honest fallback, so nobody is silently misdetected. Vitest pins: x86 hint -> macos-x64, arm hint -> macos-arm64, and the deliberate no-hint arm64 default on the frozen Intel UA. Agent-assisted change.
