What's New

Multi-Session Authentication Coordination

This release adds lock-based synchronization to prevent race conditions when multiple Claude Code sessions attempt to authenticate simultaneously.

Features

• Auth Lock: Global .auth-in-progress lock prevents concurrent auth races
• Wait for Auth: Isolated profiles now wait for any in-progress authentication before cloning the base profile
• Automatic Reuse: If another session completes auth while waiting, the shared state is automatically reused

Environment Variables for Multi-Session Support

# Add to ~/.bashrc or ~/.zshrc
export NOTEBOOK_PROFILE_STRATEGY=isolated
export NOTEBOOK_CLONE_PROFILE=true

• NOTEBOOK_PROFILE_STRATEGY=isolated - Each session gets its own Chrome profile
• NOTEBOOK_CLONE_PROFILE=true - Clone authenticated base profile into isolated instances

How It Works

1. Session A starts authentication → acquires lock → clears old auth → opens browser
2. Session B starts → needs isolated profile → waitForAuthComplete() detects lock → waits
3. Session A completes login → saves state → releases lock
4. Session B continues → clones now-authenticated profile → works immediately
