Prevent accidental deletes with y/n confirmation dialog. Validate all numeric form inputs (interval, port, timeout, threshold, retries) with range checks instead of silently defaulting to zero. Escape user-supplied data in status page JavaScript to close XSS via monitor names. Persist check history to new check_history table so sparklines and uptime percentages survive restarts.
