The hook rang the terminal bell by walking the process ancestry for a process named `claude`, but nix wraps the binary so its `comm` is `.claude-wrapped`. The match never fired: the bell never rang, and the loop fell through to a non-zero exit that surfaced as a Stop hook error on every turn. Remove the hook, its script, and the Stop and Notification wiring. The tmux monitor-bell config is left in place as a general nicety.
