 ### Key Patterns
 - **GS_CoreGameState as Replication Hub:** All shared session state (chapter, phase, objectives, encounter status) writes through GS_CoreGameState which auto-replicates to all clients via OnRep → dispatcher.
+- **Tag-Driven Everything:** No booleans, no strings. All state is GameplayTags compared via `HasTag()`/`MatchesTag()`. Tags are split across **11 per-category Data Tables** (`DT_Tags_Player`, `DT_Tags_Interaction`, etc.) registered in Project Settings → Gameplay Tags.
+- **DA_GameTagRegistry** uses an `Array<Data Table>` to iterate all tables for validation and enumeration. The engine's `UGameplayTagsManager` merges them automatically at runtime.
 - **GamePhase transitions are server-authoritative:** `SetGamePhase()` checks `HasAuthority()`. Clients receive phase changes via `OnRep_GamePhase` → `OnGamePhaseChanged` dispatcher.
 - **Interface calls route through server:** `I_Interactable.Execute_OnInteract` must be called server-side. Clients call `Server_Interact` RPC → server validates → calls interface.
 - **Data Assets are client-ready:** All `DA_*` assets load identically on all instances from disk. No replication needed.
