+- Chinese-first defaults: OmarchyCN ships Simplified Chinese as the default UX. User-visible strings in `default/omarchy/omarchy-menu.jsonc` (all labels), `default/hypr/bindings/*.lua` (bind descriptions, including the generated workspace/group/panel loops), `bin/omarchy-menu-keybindings` (its merge list and priority patterns must match the shipped Chinese descriptions), `bin/omarchy-update-confirm`, and `install/user/first-run/*` notifications are Chinese with brand names kept in English; menu search stays reachable in English through leaf ids. When syncing upstream, translate new strings in these files and resolve string conflicts toward our Chinese text.
+- Default set changes vs upstream: `install/omarchy-base.packages` adds fcitx5-rime/chinese-addons/configtool and drops aether/libreoffice-fresh/obs-studio; the Basecamp/Discord/HEY/Google/WhatsApp/X launchers, their webapp keybindings, the whatsapp-slim extension, and the HEY mailto handler are removed (preinstall add/remove lists, launcher.hides, chromium flags, and mimeapps stay in sync); `install/user/cn-chinese.sh` seeds IME/font config on zh_CN systems
+- AI: `cn/registry/` drives providers (DeepSeek/Kimi/Z.AI/MiniMax) with zero-code adapters; `omarchy-default-agent` also accepts kimi (official installer script, not mise) and deepcode (mise npm); the Default Agent menu carries them plus an AI Hub combo entry
+- Upstream sync: `.gitea/workflows/upstream-sync.yml` opens a PR per upstream change; keep upstream file edits minimal and inventoried (currently: one `GROUP_DESCRIPTIONS[cn]` line in `bin/omarchy`, the localized menu/bindings/update/first-run surfaces above, the western-app removals above, a rewritten `README.md` (known recurring sync conflict, resolve toward ours), `AGENTS.md` additions, and two `.gitignore` lines)
+- cn tests: `test/shell.d/omarchycn-test.sh`, `test/shell.d/omarchycn-ai-test.sh`; localized UI expectations live in the upstream suites (menu, keybindings-menu, hyprland-default-config, binding-conflicts, clock, screenrecording, update-disk-space)
