feat(desktop,web): open editors on this device for routes the user opts in - #33015
On the desktop app, Open in for a saved environment that is not the local one (a relay, or a saved bearer route such as a tunnel, VM or forwarded port) either offers no editor ("No SSH route to …") or builds an SSH deep link back to the host. When the project paths really are the same on this computer (a shared mount, a forwarded VM folder, a bind mount), there is no way to open them in a local editor.
The app deliberately does not infer locality from a loopback address, because 127.0.0.1:<port> can be an SSH tunnel to a VM or container, so "loopback means same machine" would be wrong. Related open PRs take other approaches to "is this route local": #25247 classifies saved loopback routes as local, #21661 matches a background service by environment id, and #25331 falls back to a local lookup for missing remote links. This PR is the explicit, user-chosen alternative and does not guess.
Change
An explicit, client-device-local override, off by default:
Opt-in: the desktop Open in menu gets Editor location: Automatic / This device. The choice is stored per desktop installation and per route (environment id plus route kind, plus connection id for saved bearer routes). Another route, another installation or restored profile data starts on Automatic. The stored list is excluded from the legacy localStorage import, and the install id lives in a file in the app's user-data directory, not in Chromium storage, so importing storage cannot grant the opt-in to another install.
Eligible routes: relay and saved bearer routes only. SSH, primary and desktop-managed (local:) routes keep their existing paths and never show the option. No loopback inference.
Launch: a new main-window-only IPC method (desktop:open-local-editor) starts the editor on this machine. It rejects callers other than the main window, requires an absolute path that exists locally, rejects control characters, resolves the editor with the shared resolveEditorCommand, and spawns argv without a shell (refusing if the resolver would need one). path:line[:col] is supported with the same launch styles as the server launcher. A failure shows an error toast and never falls back to the server or an SSH link.
Entry points covered: Open in picker and its menu, the favorite-editor shortcut, useOpenInPreferredEditor, the file context menu, and chat Markdown file links ("Reveal in file manager" is not offered for this route, since the path may not be a path on the host's file manager).
Default behavior unchanged: with the option on Automatic, the resolver returns exactly what it did before.
Docs: a short section in docs/user/remote-access.md.
Opt-in locality is not tunneling: this does not forward anything and never contacts the environment to open a file. It just starts a local editor for the same absolute path. If the path does not exist on this device the user gets an error.
Screenshots
Before opening the menu (Automatic, the default):
With the menu open, Editor location: This device selected:
Scope and approval
I do not have a prior maintainer-approved discussion for this. I am submitting it as a focused configuration option for an established capability (Open in an editor), not a product-default change: Automatic stays the default, nothing changes for existing routes, and the option is limited to the desktop app. I understand the direction may still be declined or reimplemented, and that #25247 / #21661 / #25331 cover adjacent cases.
Manual, real GUI: on a saved route to another environment, chose Editor location: This device and clicked Open in → Zed. Zed opened the expected folder on this computer. Automatic-mode behavior was covered by the tests below, not re-checked by hand.
vp run check:changed on the rebased branch: format, lint, knip (both steps), typecheck of 36 affected packages, tests for the changed files (14 files, 83 tests passed in the main run, plus 6 in the React Compiler coverage run) and React Compiler coverage all passed.
Tests added or extended: localEditorLaunch.test.ts (argv with no shell for awkward path names, line/column styles, missing/relative paths, unsupported editor, unavailable editor, spawn failure), editorClientId.test.ts, window.test.ts (non-main-window caller refused), legacyLocalStorageMerge.test.ts, remoteOpen.test.ts (loopback not inferred, route/install scoping), and browser tests OpenInPicker.deviceLocal.browser.test.tsx, remoteOpen.clientIdFailure.browser.test.tsx, remoteOpen.probe.browser.test.tsx. I also had to update two existing tests (editorPreferences.test.ts, OpenInPicker.browser.test.tsx) because their module mocks need the new hook.
Not checked: macOS and Windows; web and mobile (the option is desktop-only by design); a GUI check of every entry point other than the Open in menu; CI's full test suites, build and release smoke.
Limitations: on Windows, VS Code-family editors resolve to .cmd launchers that need a shell; the local launch refuses them with an explicit unsupported-launcher error instead of using a shell. It relies on identical absolute paths on both machines. Editors are resolved through the shared resolveEditorCommand from the desktop app's environment, so an editor that resolver cannot find is reported as unavailable; I did not test sandboxed installs. Editor-specific behavior was checked manually only for Zed on Fedora.
Written with core-router (omniroute) in the OpenCode harness.
Review follow-up
Addressed bot review feedback in 939c706: device-local mode now probes every launchable editor (Kiro, Trae and Antigravity have no SSH scheme and were missing), direct-path editors such as Zed keep path:line:col, shell-only Windows launchers report unsupported-launcher instead of unsafe-path, and the Markdown preferred-editor label follows the route mode.
…ts in
A saved route that points at another machine, a tunnel or a VM never
implies that its files exist on this computer, and loopback addresses are
not inferred to be local. Add an explicit per-install, per-route
"Editor location: This device" choice in the desktop Open in menu.
When enabled, the desktop launches the editor on this computer for the same
absolute path through a main-window-only IPC method. The launcher requires
an existing absolute path, spawns the editor argv without a shell, and
never falls back to the server or an SSH link. Automatic stays the default,
and SSH, primary and desktop-managed routes keep their existing behavior.
Macroscope's review found this PR requires human approval — The feature adds opt-in local editor launching while retaining Automatic as the default. The new @effect-diagnostics nodeBuiltinImport:off suppression in editorClientId.ts:1 requires human review of that exception.

Walkthrough
The desktop app adds IPC methods to identify the installation, discover local editors, and launch an editor on this device. The web app adds a per-install, per-route preference and uses the desktop bridge for editor actions when device-local mode is active.
Changes: Device-local editor opening
Layer / File(s)
Summary
Local editor contract and launch packages/contracts/src/ipc.ts, apps/desktop/src/ipc/methods/editorClientId.ts, apps/desktop/src/ipc/methods/localEditorLaunch.ts, apps/desktop/src/ipc/methods/*.test.ts
The IPC contract defines local-editor request and result schemas. Desktop methods read or create a per-install client ID and validate launch requests before starting an editor. Tests cover ID handling, path validation, editor arguments, and spawn outcomes.
The desktop registers client-ID lookup, local-editor discovery, and local-editor launch channels. The preload bridge exposes these methods. The launch handler accepts requests only from the main window renderer.
The web app stores the device-local choice by installation and eligible route, then applies it to remote-open resolution. Tests cover route keys, preference updates, client-ID lookup failure, and editor discovery. Legacy migration excludes the preference key. The guide describes preference scope and behavior.
The picker, shortcut, preferred-editor hook, and file context menu use the desktop bridge in device-local mode. Tests cover route-specific settings and local launch behavior.

A failed local launch can change the editor subsequently selected in Automatic mode. The Windows launcher limitation is intentional and reported accurately.

Explanation
The title "feat(desktop,web): open editors on this device for routes the user opts in" matches the main change: an opt-in, device-local editor-launch option for eligible remote routes in the desktop and web apps. The changeset adds the device-local mode, the main-window-only open-local-editor IPC method, and the Open in picker and related entry points. The title is concise, uses a conventional-commit prefix, and avoids file lists. It is 74 characters, which is within a reasonable length, though it is slightly long.
Full details: Description check
Explanation
The description follows the repository template's sections: Problem, Change, Scope and approval, and Verification. The Problem section explains the expected behavior and the environment. The Change section explains the opt-in design, the eligible routes, the launch path, and the entry points. The Scope and approval section states openly that no prior maintainer-approved discussion exists and explains why the change should count as a focused configuration option. The Verification section lists the manual Fedora/Zed check, the automated checks, the tests added, and what was not checked. Screenshots are included for the UI change. The template also asks for the model and harness used, and the description ends with a mention of the harness ("Written with core-router (omniroute) in the OpenCode harness"), so that item is covered. The main gap is the Scope and approval section: the template requires a linked triaged issue or maintainer approval for new features, and the author admits none exists. The author argues the change is a configuration option, but the template says adding a setting alone is not an approval exemption and that broader behavior changes still need approval. Whether that argument is enough is a maintainer judgment, so the description is mostly complete but its scope justification is contested.

Use the client editor list for the preferred-editor label in device-local mode.
Line 627 resolves preferredEditor from the server availableEditors. In device-local mode, useOpenInPreferredEditor opens the file with resolveAndPersistPreferredEditor(clientEditors). clientEditors is the list of editors found on this device.
The two lists can differ. A stored editor may exist on the server but not on this device. The server config may also be null, which makes availableEditors empty. In both cases the menu label from openInEditorMenuLabel(preferredEditor) names a different editor than the one that opens. The picker, shortcut, and file context menu already switch lists by mode.
Select the list by mode. Import useRemoteCapableEditors from ~/remoteOpen next to useRemoteOpenResolution.

Update the preferred-editor selection used by `openInEditorMenuLabel` to use the
client editor list when `remoteOpen.state.mode` is `device-local`, and retain
`availableEditors` for other modes. Obtain the client list with
`useRemoteCapableEditors` alongside `useRemoteOpenResolution` so the menu label
matches the editor opened on the device.
Match the touch density and expose the selected state in the new location items.
Every other MenuItem in editorItems sets density={presentation === "menu" ? "touch" : "default"}. The three new items omit it. In presentation="menu" they render with smaller touch targets than their neighbors.
The selected state is only a trailing "✓" in the label text. Assistive technology reads it as part of the name. If components/ui/menu.tsx exports a radio-item primitive, use it for the Automatic and This device choice.

- Description check:
Add before/after screenshots (or a short recording) of the Open in picker with
the new Editor location option, since this PR changes UI. Reconsider the Scope
and approval section: the template requires a linked triaged issue or a
maintainer discussion with explicit approval for behavior changes of this kind.
Either link that approval or explain why this change qualifies as a focused
configuration of an established capability, with reference to what already
exists and what the option controls. The description currently says no approval
exists, so the PR needs a maintainer decision on scope before it can meet the
template.

Persist the device-local editor only after a successful launch.
If the stored editor is absent from clientEditors, resolveAndPersistPreferredEditor writes a fallback before openDeviceLocalEditor runs. A missing local path can therefore change the shared t3code:last-editor preference even though nothing opened. When the user returns to Automatic mode, the previous editor choice is lost. Resolve the candidate without writing it, then persist it after a successful launch. (raw.githubusercontent.com)
