[BUG] Claude Code tab unresponsive — process exits with code 1 (auth not passed in bare mode)

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet

What's Wrong?

Environment:

• Claude desktop app: v1.1.9669 (macOS)
• Claude Code: v2.1.87
• macOS: Darwin 24.5.0
• Auth method: claude.ai OAuth (Pro subscription)

Description:
The Claude Code tab stopped working a few days ago. The UI loads correctly, I can type a message and press Enter, but
nothing happens — no response, no cursor activity.

Root cause identified:
The app launches the Claude Code binary with --bare mode, which skips keychain/OAuth reads. However, the auth token is
not being correctly passed to the binary. Running the binary manually in bare mode confirms it exits immediately with:
Not logged in · Please run /login
Exit: 1

The app logs confirm this:
[info] [oauth] using cached token for orgId=...
[info] Starting local session ...
[error] Session query error: Claude Code process exited with code 1
[info] unhealthy cycle (hadFirstResponse=false, reason=no_response)

The binary works fine when run directly from Terminal (claude or with --plugin-dir). Only fails when launched by the
Claude app.

Workaround: Using claude directly in Terminal.app works fine.

What Should Happen?

Expected: Claude Code responds normally
Actual: Silent failure — process exits with code 1 before any response
