同一份物理：src/shared/physics.ts 的 step(map, state, buttons) 伺服器和客戶端共用，固定 30 tick、不讀時間也不用亂數。狀態每步都轉成 f32，跟快照的精度一樣，所以客戶端從快照重播會跟伺服器算出完全相同的位置。測試在 6 tick 延遲下跑 600 tick，修正量是 0。
伺服器只信輸入：客戶端送的是按鍵，不是座標。一個輸入只走一步，佇列最多存 8 個、每 tick 平均只消耗 1 個，連發輸入也跑不快。
快照省頻寬：每 2 tick 送一次，帶上這個客戶端最後被處理的輸入序號。完整快照每個玩家 29 bytes，平常送的是跟上一個快照的差量，站著不動的玩家只要 4 bytes，走路時通常只多 x 的 4 bytes。
延遲補償：攻擊者看到的別人是過去的位置（網路延遲＋內插延遲），所以客戶端每個輸入都附上「畫面上別人停在哪個 tick」。伺服器保留每個玩家最近 15 tick 的位置，判定命中時把目標倒回那個 tick 再比對攻擊範圍。最多只倒回 500 ms，延遲太高的玩家不能打到太久以前的位置。
設計上的取捨寫在 docs/design.md。封包格式定義在 protocol.yaml，欄位表見 docs/protocol.md（用 pktspec 產生）。
