+- Extended US-011 with bidirectional combat isolation between opted-out players and the Tyrant, Assassin, Fixer, or Tamer while the event is running.
+- Direct player attacks and player-fired projectiles are cancelled at highest event priority, and the attacker is told that the target has chosen not to participate in the Tyrant event.
+- Paused, unstarted, and unrelated combat remains ordinary Minecraft gameplay.
+- Verified both attack directions, every Tyrant-side class, projectile attribution, lifecycle gating, and unrelated combat with automated tests.

+
+- US-011 is reopened for test-first running-event combat isolation between opted-out players and the Tyrant or Tyrant-side class holders.
+- Paused and unstarted gameplay remains ordinary Minecraft combat; blocked direct and projectile attackers receive a concise Tyrant event participation message.
