MOVEMENT SECURITY CLIENT MOD - SECURITY BENEFITS OVERVIEW
This document explains how the Movement Security Client Mod enhances the security of your Minecraft server when paired with the corresponding server-side plugin.

The mod acts as a trusted agent running on the player's computer, providing information that the server cannot normally access.

AUTOMATED MOD ENUMERATION & INTEGRITY CHECK
What it does: Upon joining the server, this mod scans the player's Fabric Loader environment and creates a complete list of all installed mods (names and IDs).

Security Benefit: Detect Cheat Clients: The server can cross-reference this list against a database of known cheat mods (e.g., "Wurst", "Meteor", "X-Ray"). Whitelist Enforcement: You can configure the server to only allow players who have a specific set of approved mods installed. Bypass Prevention: Standard server anti-cheats can only guess what mods a player has based on their behavior (packets). This mod reports exactly what files are loaded in memory.

REAL-TIME CHAT REPORTING & MONITORING
What it does: The mod hooks directly into the Minecraft game engine (specifically the ClientPlayNetworkHandler.sendChatMessage method). Whenever a player attempts to send a chat message, this mod sends a parallel "ChatReport" packet to the server.

Security Benefit: Unfiltered Chat Logs: Some cheat clients or "auto-text" macros might try to bypass server-side chat filters or logging. This mod reports the raw text the player typed, ensuring the server sees the original intent. Command Verification: It helps verify that chat commands executed by the player were actually typed by them and not injected by a malicious script or external program.

CLIENT PRESENCE VERIFICATION (HANDSHAKE)
What it does: The mod communicates using a custom network channel (movement:security).

Security Benefit: Enforced Installation: The server plugin can check if a player is sending these security payloads. If a player joins but does NOT send the mod list or chat reports, the server knows they are not using the official security client. Kick/Ban Automation: You can configure the server to automatically kick any player who refuses to install this mod, creating a "walled garden" where all participants are verified to be running your security software.

TECHNICAL SUMMARY
Channel: movement:security Payload Types:

ModList: Sent once on join. Contains list of all Fabric mods.
ChatReport: Sent every time the player chats. Contains raw message content.
By enforcing the use of this client-side mod, you bridge the "trust gap" between the server and the player, significantly raising the difficulty for cheaters to operate undetected.
