Safety

LaunchGuard remains read-only.

It does not execute configured commands, modify server state, send network calls, install plugins, download plugins, enable or disable plugins, reload other plugins, teleport players, modify worlds, modify blocks, modify economy data, modify permission data, change whitelist state, force-load chunks, stop the server, restart the server, or block startup.

Notes

LaunchGuard is a pre-launch diagnostic and reporting plugin. It does not fully test plugin behavior and does not verify plugin runtime correctness.
