1. Run loopback validation test

• 1.1 Start Unity Editor with server + client in loopback mode
• 1.2 Hold steady turn-and-move input (e.g., turn=0.5, throttle=1) for 10+ seconds
• 1.3 Observe MainUI correction text (校正：pos差=X rot差=Y°) — record observed values

2. Evaluate results

• 2.1 If pos差 < 0.01 and rot差 < 1° consistently: jitter is resolved, proceed to Step 5
• 2.2 If corrections remain large or jitter is still visible: document residual error for Step 5

观察结果： 抖动仍然明显（corrections 仍然较大），需要 Step 5 进一步诊断和回归覆盖。

3. Complete

• 3.1 Mark TODO.md Step 4 as complete
