What changes

Upstream quattro moved past omacom#18378 (f428bb4fe), which is what #129 merged. Ninety-nine commits replayed onto current quattro, through e6554e02d (Acer Aspire 16 AI speakers, omacom#18544). No merge commits. One follow-up commit repairs the agents-panel replay. Fork delta vs e6554e02d is the same 256 paths as quattro vs f428bb4fe. On the 194 paths upstream did not touch, the added and removed lines are unchanged. Face, Grok Bot, Cursor, linux / linux-headers, and the dropped translation-sync workflow stay.

• Google Chrome is the default browser on new installs. Bundled extensions install from signed CRXs, read as files because libarchive 3.8.10 cannot stream them. Chrome opens straight to a window, gets the 1Password extension and the Snapdragon flags Chromium already had, and takes its flags from /etc/skel. A flags file that cannot be written does not hold the other browser back. The Chromium Account setup is gone, because Chrome signs in to Google. Web apps fall back to Chromium where Chrome is not installed. Existing 1Password native-host registrations admit the Chrome extension ids, and the extension keys stay in 1Password. Where Chromium already has 1Password, a migration seeds it for Chrome. The dock pin is Files and Chrome.
• The agents panel shows the tailnet's shared models. A model another machine shares can be paired, used, and disconnected. Sharing is offered only where Tailscale can serve it, and only while the model is running; a stopped model stays shared and is served again when it starts. Pair and Disconnect are per model. A host that is already paired connects the next model without another SSH prompt. Sharing sets up the SSH server first. Disconnect is offered only while the paired model is running on its host, and it forgets the model here without stopping it there. The keyboard lands on Launch, past Pair, Disconnect, and Share. A model shared or unshared elsewhere shows up within two seconds. The line says how many machines use it, and its speed is the output speed alone. Stopped tailnet models are not drawn. A stopped model on this machine links its error to its logs; a tailnet model's logs stay on its host. The action marks are play and the Tailscale mark (Use play and the Tailscale mark for network model actions omacom/omarchy#18511). Use is the word for an unpaired network model, and pause disconnects.
• Agent moves up in the menu. Setup > Agent holds Harness and Instructions (the file was AGENTS.md). Keyboard, Input, Language, and Network sit below Config. Agent is a root item, with Make something, whose prompts are the same ones the panel's starters run. Learn sits above About. Linked instructions are kept and shared with Grok accounts. Super+Ctrl+X opens the agents panel. The migration unbinds that default before a personal bind of the same keys, including an inline bind, and only when the old dictation toggle is what it is replacing.
• Text files follow the editor you picked. The menu selection is written the way GLib reads mimeapps.list, including CRLF, spaced headers, a repeated type's last line, and a type plus its aliases. Every app opens text files in that editor, on existing installs too, one file per launch. A choice that lives only in the older ~/.local/share/applications/mimeapps.list is kept. The desktop's own list does not hide it.
• Files keeps what Nautilus used to pull in. xdg-user-dirs is installed again (Install xdg-user-dirs, which left with Nautilus omacom/omarchy#18416). Replacing Nautilus removes only Nautilus's own packages and brings Papers and xdg-user-dirs back. A terminal opened over Files starts in the folder Files is showing. Folio's preview picks its own size (Let Folio's preview pick its own size omacom/omarchy#18532).
• Icons are Adwaita. Yaru leaves the base packages and existing installs. Every theme uses Adwaita's icons and no longer ships an icon theme of its own.
• Omarchy apps build with CMake. CMake replaces qmake, and it is installed on existing machines.
• Hardware. The Purwa device trees are listed for the UKI (List Purwa device trees for the UKI omacom/omarchy#18426). The Surface Laptop 8 gets its board setup, including on existing installs (Add Surface Laptop 8 board setup omacom/omarchy#16968, Set up the Surface Laptop 8 on existing installs omacom/omarchy#18435). The LCD Surface Pro 11 (Snapdragon X Plus) is set up on its own device tree (Set up the LCD Surface Pro 11 (Snapdragon X Plus) on its own device tree omacom/omarchy#18276). The HP OmniBook X 14 gets Wi-Fi board data and shows the disk unlock prompt (Give the HP OmniBook X 14's Wi-Fi card board data omacom/omarchy#18510, Show the disk unlock prompt on the HP OmniBook X 14 omacom/omarchy#18509). The Acer Aspire 16 AI gets working speakers and microphones (Give the Acer Aspire 16 AI working speakers and microphones omacom/omarchy#18544). ARM installs get pipewire-jack and gst-plugin-pipewire (Install pipewire-jack and gst-plugin-pipewire on ARM omacom/omarchy#15782).
• A few smaller ones. The screen-recording indicator shows the recorded microphone's level. Spotify ships as a default web app, with its icon namespaced (Ship Spotify as a default web app omacom/omarchy#18485, Namespace the Spotify web app icon omacom/omarchy#18539). Netflix is a default web app on new installs (Add Netflix as a default web app on new installs omacom/omarchy#18480). Qwen Code opens on local models, and those and paired ones count as local usage (Open Qwen Code on local models, and count them and paired ones as local omacom/omarchy#18515). The omarchy-local provider counts as local usage (Count the omarchy-local provider as local usage omacom/omarchy#18506). The update bootstraps its signing keys without public keyservers (Bootstrap signing keys without public keyservers omacom/omarchy#18508). Translations run through Update translations omacom/omarchy#18521.

Three conflicts. The dock pin keeps Files and takes Chrome. The theme setup drops Yaru and keeps the Chrome and Chromium first-run preferences. The agents panel keeps the fork's hidden-provider list (a paused collector with nothing to show stays off the page, and a unified pool is not drawn twice) and takes the tailnet controls. A replay of that panel had left a second share action, which would not parse, and had treated a tailnet model's error as a local log link. The follow-up commit removes the extra action and limits the log link to this machine.

Verification

• Cherry-pick of the 99 non-merge commits from 56a103fef through e6554e02d applied onto quattro c08496a20. git diff --name-only of HEAD vs upstream e6554e02d is the same 256 paths as quattro vs f428bb4fe. On the 194 paths upstream did not touch, the added and removed line counts match. The other 62 paths are the fork delta merged with upstream. A three-way merge of those 62 against f428bb4fe matches HEAD except the agents panel, whose four conflicts are the hidden-provider list versus the tailnet controls, resolved as above. linux and linux-headers are still in the other-packages list. Face, Grok Bot, and Cursor are still in the menu. The translation-sync workflow is still absent. All 203 i18n JSON catalogs parse.
• bash test/shell.d/agents-panel-test.sh passed (95), including sharing, SSH-before-share, hidden ids in the saved order, and local-model progress.
• bash test/shell.d/default-agent-test.sh passed (48), including --prefer-local opening the running local model and the usual agent otherwise.
• bash test/shell.d/default-apps-test.sh passed (20), including an editor choice reaching every app, GLib's reading of mimeapps.list, and new installs opening text files in the default editor.
• bash test/shell.d/menu-test.sh passed (110), including the Omarchy-font glyphs the menu draws.
• Could not boot a Surface Laptop 8, a Surface Pro 11, an HP OmniBook X 14, or an Acer Aspire 16 AI, and this checkout has no Omarchy session, so the panel, Chrome, Files, and the new hardware were not checked on a machine. No other sync was open.

Screenshots

No visible change: this checkout has no Omarchy session, so nothing was drawn here. Chrome as the default browser, the tailnet models in the agents panel, the Agent menu, and Adwaita icons are visible on a machine; the tests above cover the behavior that can run here.
