echo
echo "🎯 DIAGNOSIS: .zshrc Configuration Not Applied"
echo "=============================================="
echo
echo "The _smart_tab_handler function exists but the shell session hasn't"
echo "loaded the complete .zshrc configuration that sets up the bindings"
echo "and ghost text system."
echo
echo "EVIDENCE:"
echo "✅ _smart_tab_handler function: EXISTS (from shell snapshot)"
echo "❌ Tab key binding: Still default 'expand-or-complete'"
echo "❌ Ghost text variables: UNSET (GHOST_SHELL_PID, _ghost_completion_active)"
echo "❌ fzf-tab plugin: NOT LOADED"
echo "❌ Custom zstyles: NOT CONFIGURED"
echo
echo "Current Tab binding: $(bindkey '^I')"
echo "Expected: \"^I\" _smart_tab_handler"
echo
echo "SOLUTION:"
echo "The user needs to either:"
echo "1. Start a fresh zsh session: exec zsh"
echo "2. Source the .zshrc manually: source ~/.zshrc"
echo "3. Or restart their terminal"
echo
echo "WHY THIS HAPPENED:"
echo "- The .zshrc file contains all the correct code"
echo "- But the current shell session was started before the .zshrc changes"
echo "- Or there was an error during .zshrc loading that prevented full setup"
echo
echo "VERIFICATION TEST:"
echo "After sourcing .zshrc, these should be true:"

cat << 'EOF'

# Test these after sourcing .zshrc:
bindkey '^I'                    # Should show: "^I" _smart_tab_handler  
echo $GHOST_SHELL_PID          # Should show: [process_id]
echo $_ghost_completion_active # Should show: false
zstyle -L ':fzf-tab:*' fzf-bindings | head -1  # Should show fzf-tab config

echo
echo "=== ROOT CAUSE CONFIRMED ==="
echo "The issue is NOT with the _smart_tab_handler implementation."
echo "The issue is that the shell session hasn't loaded the .zshrc configuration"
echo "that binds Tab to _smart_tab_handler and sets up the ghost text system."
echo
echo "NEXT ACTION FOR USER:"
echo "Run: source ~/.zshrc"
echo "Then test Tab completion with ghost text."
