⚡ プロトコルアーキテクチャ

ツールチップはクライアント側で描画されますが、ゲームルールはサーバー上に存在します。Durability MultiplierはFabric Networking APIを使用して、全73個の静的ルールおよび動的ルールのスナップショットをクライアントへ配信します。

    Server->>Net: GameRules.set() [GameRulesMixin TAIL]
    Net->>Client: Broadcast DurabilityPayload to all players
    Client->>State: DurabilityClientState.apply(payload)
    Client->>UI: Tooltips update immediately without relog

📦 ペイロード構造 (76のフィールドと動的マップ)

DurabilityPayloadは、VarIntやBoolean、マップコーデックを用いて全ルールと動的マップを効率的にシリアライズします：
