echo "=== Key Behavioral Points ==="
echo "✅ None state: Clears sort indicators but keeps current data (NO query re-execution)"
echo "✅ Ascending/Descending state: Calls sort_results_data() to get sorted data"
echo "✅ Sort state properly advances via get_next_sort_order()"
echo "✅ AppStateContainer handles all sort state management"

echo
echo "=== Viewport Reset Analysis ==="
echo "❌ OLD behavior (fixed): None state would call execute_query(), resetting viewport"  
echo "✅ NEW behavior (current): None state just clears indicators, preserves viewport"
echo "✅ Sort indicators should show ↑ ↓ for active sorts"
echo "✅ No more double-handling of sort actions"

echo
echo "=== Manual Testing Instructions ==="
echo "1. Load CSV file with ./target/release/sql-cli test_sort.csv"
echo "2. Press 's' on Name column - should sort ascending (↑)"
echo "3. Press 's' again - should sort descending (↓)" 
echo "4. Press 's' third time - should clear sort (no indicators, same data)"
echo "5. Press 's' fourth time - should sort ascending again"
echo "6. Use F5 to debug dump and verify SortState in AppStateContainer"

echo
echo "✅ Sort viewport behavior test completed!"
