For interactive TUIs, split text and Enter into separate sends to avoid paste/multiline edge cases:
tmux send-keys -t shared -l -- "Please apply the patch in src/foo.ts"
sleep 0.1
tmux send-keys -t shared Enter
for s in $(tmux list-sessions -F '#{session_name}'); do
echo "=== $s ==="
tmux capture-pane -t $s -p 2>/dev/null | tail -5
done

Keep conditional logic in the caller; use TaskFlow for flow identity, child-task linkage, waiting state, revision-checked mutations, and user-facing emergence.
