What's Wrong?

Bug description
Claude Code Desktop connects to a remote server via SSH but immediately disconnects after sending any prompt. The remote process (ccd-cli) exits with code 1 before processing input.
Environment

Desktop version: 1.1.7464
Claude Code CLI: 2.1.79
ccd-cli version on server: 2.1.78
Client OS: macOS
Server OS: Ubuntu 24.04.4 LTS (Hetzner VPS)
Auth: SSH key (no password)

Steps to reproduce

Add SSH remote connection in Desktop (host: root@<ip>, port 22, identity file configured)
Connect — connection shows as active
Type any prompt and send
Desktop immediately shows "Disconnected"

Remote server log (~/.claude/remote/remote-server.log)
[process.Manager] Process <uuid> started, PID=XXXX, command=/root/.claude/remote/ccd-cli
[process.Manager] Read 93 bytes from stderr for process <uuid>
[process.Manager] Process <uuid> exited with code 1
[process.Manager] WriteStdin: process <uuid> not found
[Server] RPC response sent: id=X, hasError=true
Root cause identified
The Desktop spawns ccd-cli without a TTY. Running ccd-cli directly via SSH without -t hangs or exits with code 1. With -t (TTY allocated) it works:
bash# Fails (exits code 1, same as Desktop)
ssh root@server "/root/.claude/remote/ccd-cli --print 'hello'"

Works (with TTY)

ssh -t root@server "/root/.claude/remote/ccd-cli --print 'hello'"

→ Hello! How can I help you today?

EXIT: 0

Workaround
bashssh -t geroca "claude"
Works correctly. The issue is specific to Desktop's SSH spawning — it does not allocate a TTY for the ccd-cli process.
Additional notes
This worked correctly until approximately 19 March 2026. Suspected regression introduced in a recent Desktop or ccd-cli update.
