 ## 2026-10-06 (pm, 7) — tmux ctrl+h/j/k/u in copy-mode
 Done: copy-mode-vi table had stock C-h cursor-left, C-u halfpage-up, C-j copy, so no-prefix pane moves became text nav once scrolled. Four keys rebound select-pane in copy-mode-vi, live reload OK. Merged bugfix/tmux-copy-mode-ctrl-nav → develop (8b6ed6b). Open: deployed ~/.config/tmux/tmux.conf on this Mac predates alt+v/wheel/this fix, `./install.sh` not re-run.

+## 2026-10-06 (pm, 8) — tmux drag "syntax error" in claude panes
+Done: MouseDrag1Pane binding had `\"` inside '...' (literal since tmux 3.0); branch for mouse-tracking panes (claude fullscreen, vim mouse=a) failed to parse → "syntax error", no selection. Backslashes dropped, pitfall noted in conf. Deployed to ~/.config/tmux/tmux.conf + source-file, live binding verified (`forwarded-to-app`). Branch bugfix/tmux-drag-syntax-error (31f8400), not merged. Closes the "deployed conf stale" open item.
