[BUG] Claude Desktop Code tab silently fails on macOS 14.4 arm64 - bundled binary exits code 1

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Environment:

• macOS: 14.4 (Sonoma) arm64 (Apple Silicon)
• Claude Desktop: 1.569.0
• Bundled claude-code binary: 2.1.87
• CLI (separately installed): 2.1.91 - works fine in Terminal

Bug:
Code tab accepts input but never responds. Binary exits with code 1 immediately.

Log evidence:
Using Claude Code binary at: .../claude-code/2.1.87/claude.app/Contents/MacOS/claude
Session query error: Claude Code process exited with code 1
CCD CycleHealth: unhealthy cycle (0s, hadFirstResponse=false, reason=no_response)

What I tried:

• Full uninstall/reinstall of Claude Desktop
• Installed native CLI separately
• Cleared all config and caches
• Granted Full Disk Access, Developer Tools, Accessibility permissions
• Initialized git repo in working directory
• Cannot modify bundled binary - Operation not permitted (SIP protected)

The CLI works perfectly in Terminal. Only the Desktop Code tab is broken.
The Desktop app needs to either update its bundled binary to 2.1.91+ or allow
fallback to the system-installed claude binary.

What Should Happen?

Claude Desktop Code Tab should work
