A test installs a type override from base_agent to coverage_agent before the environment is built, but the instantiated agent is still base_agent. What is the decisive defect?

class env extends uvm_env;
  base_agent agt;
  function void build_phase(uvm_phase phase);
    super.build_phase(phase);
    agt = new("agt", this);
  endfunction
endclass
