Astral Anti-ESP replaces everything below a configurable Y level with solid deepslate on its way to the client. The world itself is never modified no setType, no world edits, nothing changed for anyone. Break the fake deepslate and you get whatever was really there.
Freecam and xray don't need line of sight; they read the chunk data the client already holds. The only real defence is to not send it.
A faked section is a single entry palette, so it encodes smaller than real terrain deep-rendered chunks cost less bandwidth, not more. Optional cave protection restores chunks a player could actually see into, per player.
Requires PacketEvents. Paper 1.21+.
