Longer, structured ASCII-based separators with explicit boundary markers are most effective at isolating user input. PPA operates with 0.06ms overhead per request, orders of magnitude faster than model-based defenses (30-500ms), while ranking 2nd on Pint-Benchmark (97.68%) and 1st on GenTel-Bench (99.40%).",
