Run Windows 11 ARM64 guests on macOS over QEMU+HVF, with an ivshmem shared-memory transport carrying every guest channel (agent control, display/VDD, input, audio, clipboard, SSH, 9P) - no guest networking required. - tools/transport: one guest transport API, two backends (PC AF_HYPERV, Mac ivshmem); SPSC ring with an acquire-barrier fix for SSH integrity - tools/ivshmem: our own KMDF ivshmem BAR-mapping driver (no third party) - src/backend_mac: Mac-host ivshmem transport, QEMU VM lifecycle, IDD display consumer, agent/SSH proxies, ISO->disk patcher, Windows create - tools/agent + channel EXEs + tools/vdd: wired to asb_transport - tools/agent_win: staged guest payload (interim, pending JIT pull) - vendor/qemu-ivshmem: vendored QEMU 11.0.1 fork (ivshmem-plain) + LGPL source mirror for the self-contained app bundle - tools/sign/make-release.ps1: use the host-native ARM64 MSBuild so the WDK driver ApiValidator runs (the x86 validator fails on ARM64)
