SunshineCommandGuard

What's Changed Bugfix Tab-completion no longer leaks argument suggestions for commands that are blocked for the player. The asynchronous completion path now requires the command root to be runnable (visible command, hidden-but-runnable alias, or temporary grant) before serving argument completions. Hidden aliases keep their configured argument completion; blocked commands return none. Commands hidden by the anti-enumeration namespace policy are also excluded from argument completion. Testing New regression test covering blocked commands and hidden aliases. Full test suite green. Java 21 clean build verified.
