+# M10 — Gameplay Domain
+
+<!-- OPENWC_TARGET:OPEN -->
+
+## Outcome
+
+Создать независимое от Godot и packets клиентское состояние WoW 3.3.5a.
+
+## Steps
+
+- [ ] `WorldState`, typed entity registry и local player lifecycle.
+- [ ] Domain events/reducers для create/update/destroy.
+- [ ] Movement state, prediction и server reconciliation policy.
+- [ ] Targeting, unit health/power/faction и interaction state.
+- [ ] Spell/cooldown/aura presentation state minimum.
+- [ ] Inventory и quest log snapshots minimum.
+- [ ] Immutable read models для UI/render/audio.
+- [ ] Deterministic replay, state snapshots и reducer tests.
+
+## Fidelity evidence
+
+State transitions, server authority, movement flags, errors и timing сверяются с 3.3.5a. Client prediction не подтверждает combat/items/quests самостоятельно.
+
+## Exit criteria
+
+Один packet/domain replay всегда создаёт одинаковый gameplay snapshot без Node, UI или live socket.
