Re-ran the leak harness on a populated session (Phaser thread) for both unpatched and patched builds. The original 'listener leak' was transient warm-up cost, not a steady-state leak — both versions show 0 listener growth/round in steady state. The load-bearing number is forced layouts per character: unpatched (HEAD~2): 7.02 layouts/char patched (HEAD): 2.35 layouts/char (3× fewer) The patches reduce per-char forced-layout work to Blink's natural floor. Document node count and heap are flat in both builds.
