drawned/sentry — reverse-engineered prompt

Build me a Minecraft server security plugin called Sentry for a Spigot or Paper style server. I want it to act like an all in one protection layer that helps stop common abuse before it becomes a problem. It should detect and block unauthorized client mods and popular hacked clients, deal with bot attacks, reject VPN or proxy connections when needed, prevent crash item style exploits, and add OP protection and other basic server safety checks.

Please make it feel production ready, with sensible messages, permissions, config options, and clear ways for server owners to turn checks on or off. I also want a small developer API so other plugins can look up a player’s security state, see active detections, manage sessions, and listen for security related events.

Keep the code organized like a real plugin project with the API separated cleanly from the core logic. If you need details, look up the current server plugin docs and typical Minecraft plugin conventions online.
