A Docker Compose sandbox for exercising the Cartograph Minecraft plugin against real server software, with simulated player traffic via Mineflayer bots.
The rig supports six platforms (Paper, Spigot, Folia, NeoForge, Velocity,
BungeeCord) across two Minecraft version lines (1.21.x on Java 21,
26.1.x on Java 25). Plugin telemetry can be inspected locally via a tiny
Node sink, or pointed at any HTTP endpoint via CARTOGRAPH_API_URL.
