What's Wrong?

Running claude --resume <session-id> from any directory other than the one where the session was
originally started returns:

No conversation found with session ID: <session-id>

even though the session file exists in ~/.claude/projects/.

session exists

session doesn't open

What Should Happen?

Session IDs are globally unique UUIDs. --resume should search across all project folders under
~/.claude/projects/ regardless of the current working directory.

Steps to Reproduce

1. Start a Claude Code session from directory A (e.g. /)
2. Note the session ID
3. Open a new terminal in directory B (e.g. ~/AI/Claude)
4. Run claude --resume <session-id>
5. Error: No conversation found with session ID: <session-id>
