```

Comece com a reprodução em Lua `local ffi = require("ffi")` e o caminho de carregamento da biblioteca registrado em `script/library.lua`, verificando o comportamento no runtime LuaJIT configurado. Compare a resolução do require de `ffi` com o comportamento esperado de conclusão e verificação de tipos mostrado na issue; considera-se concluído quando ele não for mais reportado como desconhecido.
