SentinelCore

SentinelCore is an adaptive, confidence-based anti-cheat foundation built specifically for Paper servers. It prioritizes reliable detection and low false-positive risks over a high volume of flags by using historical evidence and adaptive behavioral baselines.

Designed with performance and stability in mind, SentinelCore operates entirely through the Paper API, meaning it does not require ProtocolLib or NMS injections to function.

🛡️ Core Features

• Advanced Movement Validation: Uses a state-aware movement model for adaptive movement-envelope validation.
• Combat & Interaction Analysis: Evaluates click-patterns using CPS and rolling timing deviation, alongside reach validation that actively compensates for latency and physical obstructions[cite: 2].
• Intelligent Exemptions: Automatically exempts players from checks during uncertain conditions like low server TPS, teleports, respawns, desynchronization gaps, and vehicle usage to protect legitimate players[cite: 2].
• Live Profile Dashboard: Staff can access a read-only GUI dashboard (/ac [player]) to view live statistics, movement profiles, reaction scores, and reach deviations[cite: 2].
• Dynamic Performance Scaling: Automatically adjusts its execution budget and check frequency based on live server TPS and player count to maintain strict server thread health[cite: 2].

⚠️ Important Notice

SentinelCore currently operates as an event-driven detection foundation[cite: 2]. When evidence thresholds are reached, it emits detailed staff alerts[cite: 2]. It does not automatically kick, ban, or punish players[cite: 2].

🌐 Localization

The plugin supports multiple languages out of the box, including English, French, Arabic, German, Turkish, Portuguese, Italian, Japanese, and Simplified Chinese[cite: 2].
