…ection + enforcement) Introduces a config-gated, server-side anti-cheat / movement-validation framework. OFF by default (AntiCheat.Enable = 0) — fully inert until enabled. Core pieces: - AntiCheatMgr: central scoring manager. Detectors only observe and score via a single RecordViolation() ingress; the manager owns ALL enforcement. Score decays over time and escalates through capped actions (log -> GM alert -> rubberband to last validated position -> kick), with an optional account-level autoban accumulator (escalating ban durations, slow hourly decay). - MovementAnticheat: per-player validator running cheap, event-driven detectors on each movement packet — fly/flag-spoof (water-walk/hover/slow-fall/transport/ swim, aura- or grant-aware), teleport/blink, speed, acceleration gate, vertical climb, root/stun-break, opcode-legality, no-clip (VMap LoS), jump (infinite/ mid-air), fall-damage suppression, packet burst, client-timestamp regression, bot-movement heuristic, and spell-cast timing (GCD bypass + cast spam). - PhysicsValidator: side-effect-free terrain-plausibility stage (float-above / below-surface), invoked only on suspicion to stay off the hot path. Integration: movement validation in the movement opcode handler; spell-injection, item-in-trade, GO-use and NPC interaction-distance hooks; cast-timing hook; server-granted movement flags recorded in the Player Set* setters so the flag-spoof detectors don't fire on legit grants; a rolling latency EWMA fed from CMSG_PING for latency-aware tolerances. GM commands: .anticheat status / report / reload / warn / jail / unjail / delete. Violations persist to character_anticheat_violation; account autoban state to account_anticheat. Time-sync, the spoof/test GM tooling, and the violation-marker visualizer are follow-ups that build additively on this core. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
