It now also looks for an explicit attacher socket and passes it to `tmux load-buffer`, so copy works when Claude Code reaches tmux through a socket instead. If neither is found, there is still no clipboard support.\n\n**Evidence**\n\n`attacher socket`\n\n- Area: Terminal UI\n- Names: `TMUX`\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 1\/5"}
