What changed and why

Brings Japanese input (Fcitx5 + Mozc, JIS 英数/かな keys) to VMs created before v0.6.0, through the Update and Launch boot migration.

• Keyboard support is automatic. ANSI/ISO/JIS keyboard support (apple-keyboard-input.lua) is installed on every boot, even after Skip and Launch. It needs no packages or network.
• Japanese input is part of Update and Launch (catalog japanese-input revision 3):
  • It installs only the missing factory packages: fcitx5, fcitx5-mozc, fcitx5-gtk, fcitx5-qt, fcitx5-configtool and noto-fonts-cjk.
  • It uses pacman -Sy --needed and checks pacman's local database. It no longer runs a full -Syu system upgrade, because the consent dialog is all-or-nothing and every older VM would otherwise get a system upgrade at boot.
  • v0.5 VMs get Mozc and the configuration tool. v0.4 VMs also get the GTK/Qt input modules and CJK fonts.
• Stock Fcitx profiles are migrated:
  • Mozc goes first on JIS Macs, for a Japanese VM language, or when the Mac's primary language is Japanese.
  • Older VMs keep an English locale, so the app now passes tryomarchy.mac_language= as a separate hint. It never changes LANG.
  • When Mozc goes first, the Fcitx keyboard follows XKBLAYOUT from /etc/vconsole.conf, as on new VMs. Mozc picks its kana table from that layout, so this fixes ろ/¥ in kana input for older VMs with the jp layout.
  • Personal profiles, shortcuts and Korean group selection are preserved.
• Unrelated, also on this branch: 5c4ccb6 makes provenance check each backported file against the last backport that touches it.

Known trade-off: -Sy without -u is a partial upgrade. A refresh is needed because Arch Linux ARM mirrors drop superseded packages. Pacman blocks broken dependency cases, but a newly built package needing a newer library than the VM has remains a small risk that grows as older VMs age.

Testing

• make test: exit 0. That covers 423 guest Python tests, 452 Swift tests (89 suites) and run-qemu-ssh-contract.test.

• New tests cover:

  • detecting missing packages and the exact pacman command;
  • matching the kana layout, including the Korean seed and repeat runs;
  • the Mac language hint on ANSI/ISO;
  • parsing /etc/vconsole.conf;
  • adding, omitting and rejecting the launcher token;
  • Swift language plumbing.

• Checked against upstream sources:

  • Fcitx5 5.1.23: ConsumeRedundantActivateKeys, the default trigger keys, and Wayland keymap handling.
  • fcitx5-mozc: kana table selection by layout.
  • xkeyboard-config: Hangul/Hangul_Hanja and apple:jp_oadg109a.
  • Pinned Omarchy: Hyprland reads XKBLAYOUT.

• Not tested on a running VM. Before release: copy a v0.5.1 VM, set the app's language to Japanese, then run Update and Launch. Confirm that:

  • only the missing packages install;
  • Ctrl+Space turns on Mozc;
  • with XKBLAYOUT=jp the profile lists keyboard-jp, mozc, chewing;
  • kana input works.

  Physical JIS 英数/かな still needs a JIS Mac, or QMP lang1/lang2 events.
