[BUG] Desktop (SSH): "Worktree location" accepts only a local path, so remote sessions always fall back to the remote $HOME

Summary

Desktop has a single "Worktree location" setting and it resolves against the local
filesystem — on Windows, a local Windows path. There is no way to enter a path on an SSH
remote. So for SSH sessions the setting can never hold a usable value, and every remote
worktree lands in the remote user's home directory at
$HOME/<repo-basename>-<16 hex>/<session-name>/, regardless of what the setting says.

A Windows path and a Linux remote path cannot both live in one field. The setting is
structurally unusable for SSH sessions.

Steps to reproduce

1. Desktop on Windows. Settings → Claude Code → Worktree location: the field offers a local

Windows path only; there is no way to specify a path on an SSH host.

1. Add an SSH connection to a Linux host and open a repository on it as the session folder.
2. Start a new session with the worktree option selected.

Expected

Some way to say where worktrees go on that remote host — and, with the setting at its default,
worktrees at <project-root>/.claude/worktrees/ on the remote.

Actual

The worktree is created under the remote $HOME, nowhere near the project:

$HOME/myrepo-a8ae6b289e243a34/
├── .claude-managed-worktrees
├── session-one-bea3e2
├── session-two-0d2256
└── session-three-3bde66

Nothing is written to <project-root>/.claude/worktrees/ on the remote.

The app writes a marker file into that home directory, .claude-managed-worktrees, which
points at the setting as the reason it chose the location — a setting that cannot be given a
remote value:

This directory holds Claude Code session worktrees placed here by the claude-ssh daemon (the "Worktree location" setting). Its subdirectories are managed checkouts; open the repository itself, not one of them, as a session folder. Safe to delete once the directory is otherwise empty.

Not caused by the remote OS

The remote is Fedora Atomic, where /home is a symlink to /var/home, so the symlink
refusals documented for worktree creation are the obvious suspect. They are not the cause:

• The fallback root the app chose, $HOME/myrepo-<hash>/, is itself under that symlink and

works fine — three worktrees in it, all healthy and registered.

• The repository root is already symlink-free (/var/home/...), so the default location

resolves to a path with no symlink in it to refuse.

• Both spellings normalize: session records are stored under the /var/home form, and the

CLI's own containment check realpaths both sides before comparing, so the two spellings are
never compared as strings.

No workaround

• A remote value in the setting: not expressible. The field is local-filesystem only.
• Per-connection setting: none. sshConfigs entries accept id, name, sshHost,

sshPort, sshIdentityFile only.

• Settings file on the remote: no key at any scope. worktree.* accepts baseRef and

bgIsolation only, so the remote host's own ~/.claude/settings.json can't override it.

• WorktreeCreate hook, the documented way to relocate worktrees: not called by Desktop —

#29716, open since 2026-03-01.

• Creating worktrees manually with git and opening each as a session folder: doesn't scale

(this repository runs 107 registered worktrees), and for the documented default location the
SSH folder picker can't open hidden directories anyway — #93909.

Asks

Any one of these unblocks it:

1. Let the worktree location be set per SSH connection, entered as a remote path.
2. Accept a value relative to the project root, so one setting resolves correctly on every host

regardless of platform.

1. Failing a setting, have SSH sessions use the documented default

<project-root>/.claude/worktrees/ on the remote rather than the remote $HOME.

Environment

• Desktop app: Claude Code Desktop on Windows
• Remote host: Fedora Linux 44 (Atomic), kernel 7.2.4
• ccd-cli on remote: 2.1.271
• Claude Code CLI on remote: 2.1.274
