Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Remote editor opening can appear available even when the required deep-link handler is unavailable, causing remote project opens to fail.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a new Zed remote-opening capability across web, desktop, and shared editor contracts, including OS protocol handling and deep-link validation. It also changes the fallback product default to offer Zed alongside VS Code, so the broader runtime and default-selection changes merit human review. You can add or adjust custom eligibility rules. Learn more. |

Related implementation: #7900 covers the same Zed SSH links and notes that Zed Preview may need to register the shared zed:// protocol before remote links open correctly. Please retain that setup guidance in this implementation. |

330-337: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winDo not use CLI availability as a remote-open fallback.
openExternalopens a remote URI scheme. If no protocol handler exists but a CLI command is onPATH, this fallback still reports the editor as available. The UI can then offer an action that cannot open the remote project.Remove this fallback, or open the project through the detected CLI instead.

- Line 1137: Update the JSDoc for probeRemoteEditors to document that it checks
registered protocol handlers in addition to installed editor CLIs, and that a
registered handler can make an editor available even when its CLI is not on
PATH. Preserve the existing fallback description for callers.

Implements the Zed remote-open use case tracked in Discussion #6801 (previously #7899). This uses the generalized remote-editor architecture rather than the dedicated Zed launcher approach from #4362.
What Changed

It is nice to have T3 Code open in your editor of choice, given that the editor supports remote editing.

Checklist
Note
Medium Risk
Changes external URL allowlisting and deep-link validation in Electron; mistakes could block legitimate opens or allow unsafe schemes, though Zed-specific guards and credential checks are added.
Overview
Adds Zed as a remote-capable editor so SSH environments can open projects via
zed://ssh/<host>/<path>on the local machine, alongside existing VS Code–stylevscode-remotelinks.Editor contracts now use a structured
RemoteEditorOpenDefinition(scheme, URL host, SSH path prefix) instead of a single optionalremoteScheme.buildRemoteOpenUrland Electron’sparseSafeExternalUrl/isRemoteEditorUrlvalidate and allow links per editor definition, including stricter rules for malformed or credential-bearing Zed URLs.ElectronShellexposeshasProtocolHandler; desktopprobeRemoteEditorsprefers registered OS protocol handlers (for GUI-only installs) before CLIPATHchecks. The web client’s browser fallback editor list expands from VS Code-only to VS Code and Zed. User docs describe Open in Zed and sharedzed://handler behavior.remoteSchemeForEditoris removed in favor ofremoteOpenDefinitionForEditor(breaking for external consumers of the old helper).Reviewed by Cursor Bugbot for commit 64c9220.
