ryanrhughes opened the NVIDIA N1x runtime proposal and aarch64 ISO proposal on October 10. Both subsequently merged into quattro on October 15, outside this issue's coverage interval: omacom/omarchy#14820 and omacom/omarchy-iso#251. Their current descriptions cover broader N1x, Snapdragon and GB10 support; those later descriptions should not be read as the original opening-day scope.
October 10 also brought 
omarchybot's Mac convergence commit to quattro, introducing platform-aware setup and boot lifecycle integration. omacom/omarchy@e1b0e5e9bb72 records that integration. Separate ISO commits attributed to Emir Beganovic, with 
emirb among their recorded participants, added unattended generic aarch64 installation and boot checks and changed live-root compression to lz4 because the generic kernel could not read zstd-compressed squashfs.
ryanrhughes also committed target installation of the Arch Linux ARM keyring and signature validation against it. This addresses installed systems rejecting signed packages during their first online package operation. omacom/omarchy-iso@2487d3b1cb7e records the repair; these commits and development merges do not establish a stable ARM release.
