DENIED_PREFIX blocked love.* and ffi.* submodule requires but had no
entry for jit, so require("jit.util") walked straight through to the
real module. jit.util is LuaJIT's own equivalent of the debug library
this file already denies by name: funcbc, funck and the rest read the
bytecode and constants of any function a chunk can reach, which is
enough to recover upvalues -- the real _G, love, io -- that the sandbox
exists to keep out of a mod's hands.
Adding "jit" to DENIED_PREFIX blocks jit.* submodule requires the same
way love.* and ffi.* already are, while leaving the bare jit global
(env.jit, handed over directly for jit.on/off/flush) and a bare
require("jit") untouched -- jit.util is not a field of that table
without its own require, so neither route was ever a way to reach it.
We already ship the DLL, but mods can't ffi-load it under the sandbox, and
the compat love.system shim wasn't passing tls* through either. So wss://
still died on stock builds. Engine loads the dialer at boot; compat forwards
those keys; clipboard/openURL stay stubbed.
