🔮 Smart Engine
🧠 Physics Prediction — Simulates vanilla gravity tick by tick. Compares predicted position to actual. Catches fly and hover that threshold checks miss.
🌐 Lag Compensation — Thresholds scale with each player's latency. No configuration needed.
🔄 Violation Decay — VL decreases over time without new flags. Clean players recover on their own.
↩️ Setback — Silent teleport to last safe position instead of disconnect.
⚙️ Actions
Every check carries its own configurable response:
| Action | Behavior | |
|---|---|---|
| ⚠️ | Warn | Alert the player, log the violation |
| 🚪 | Kick | Immediate disconnect |
| 🔨 | Ban | Permanent, automatic |
| ↩️ | Setback | Silent teleport to last safe position |
